Strategy and Strategic Leadership in Education: A Scoping Review

Strategy and strategic leadership are critical issues for school leaders. However, strategy as a field of research has largely been overlooked within the educational leadership literature. Most of the theoretical and empirical work on strategy and strategic leadership over the past decades has been related to non-educational settings, and scholarship devoted to these issues in education is still minimal. The purpose of this scoping review was to provide a comprehensive overview of relevant research regarding strategy and strategic leadership, identifying any gaps in the literature that could inform future research agendas and evidence for practice. The scoping review is underpinned by the five-stage framework of Arksey and O’Malley. The results indicate that there is scarce literature about strategy and that timid steps have been made toward a more integrated and comprehensive model of strategic leadership. It is necessary to expand research into more complex, longitudinal, and explanatory ways due to a better understanding of these constructs.


INTRODUCTION
Strategy and strategic leadership are critical issues for school leaders Davies and Davies, 2010;Eacott, 2010a;Eacott, 2011). However, strategy as a field of research has largely been overlooked in educational leadership literature Eacott, 2008a;Eacott, 2008b;Davies and Davies, 2010;Eacott, 2011). Most of the theoretical and empirical work on strategy and strategic leadership over the past decades has been related to non-educational settings, and scholarship devoted to these issues in education is still very limited (Cheng, 2010;Eacott, 2011;Chan, 2018).
The concept of strategy appeared in educational management literature in the 1980s; however, little research was produced until the 1990s (cf. Eacott, 2008b). Specific educational reforms led to large amounts of international literature mostly devoted to strategic planning (Eacott, 2008a;Eacott, 2008b;Eacott, 2011). For a long period, the concept of strategy was incomplete and confusing. The word "strategy" was often used to characterize different kinds of actions, namely, to weight management activities, to describe a high range of leadership activities, to define planning, or to report to individual actions within an organization (Eacott, 2008a).
Strategy and strategic planning became synonymous (Eacott, 2008b). However, strategy and planning are different concepts, with the strategy being more than the pursuit of a plan (Davies, 2003, Davies, 2006Eacott, 2008a;Eacott, 2008b;Quong and Walker, 2010). Both phases of plans' design and plans' implementation are related, and the quality of this second phase highly depends on planning' quality (Davies, 2006;Davies, 2007;Eacott, 2008a;Eacott, 2008b;Eacott, 2011;Meyers and VanGronigen, 2019). Planning and acting are related and must emerge from the strategy. As stated by Bell (2004).
Planning based on a coherent strategy demands that the aims of the school are challenged, that both present and future environmental influences inform the development of the strategy, that there should be a clear and well-articulated vision of what the school should be like in the future and that planning should be long-term and holistic (p. 453).
Therefore, it is necessary to adopt a comprehensive and holistic framework of strategy, considering it as a way of intentionally thinking and acting by giving sense to a specific school vision or mission (Davies, 2003(Davies, , 2006Eacott, 2008a;Eacott, 2008b;Quong and Walker, 2010).
The works of Davies and colleagues (Davies, 2003;Davies, 2004;Davies and Davies, 2004;Davies and Davies, 2006;Davies and Davies, 2010) and Eacott (2008aEacott ( , 2008b, Eacott (2010aEacott ( , 2011 were essential and contributed to a shift in the rationale regarding strategy by highlighting a more integrative and alternate view. Davies and colleagues (Davies, 2003;Davies, 2004;Davies and Davies, 2004;Davies and Davies, 2006;Davies and Davies, 2010) developed a comprehensive framework for strategically focused schools, comprising strategic processes, approaches, and leadership. In this model, the strategy is conceptualized as a framework for present and future actions, sustained by strategic thinking about medium to long term goals, and aligned to school vision or direction.
Strategic leadership assumes necessarily a relevant role in strategically focused schools. Eacott (2006) defines strategic leadership as "leadership strategies and behaviors relating to the initiation, development, implementation, monitoring, and evaluation of strategic actions within an educational institution, taking into consideration the unique context (past, present, and future) and availability of resources, physical, financial and human" (p. 1). Thereby, key elements of strategic leadership can be identified as one that: 1) acts in a proactive way to contextual changes; 2) leads school analysis and response to changing environment; 3) leads planning and action for school effectiveness and improvement in face of contextual challenges and; 4) leads monitoring and evaluation processes to inform decision making strategically (Cheng, 2010). This brings to the arena a complex and dynamic view of strategic leadership as it is a complex social activity that considers important historical, economic, technological, cultural, social, and political influences and challenges (Eacott, 2011).
Along with these authors, this paper advocates a more comprehensive and contextualized view of strategy and strategic leadership, where strategy is the core element of any leadership action in schools (Davies and Davies, 2010;Eacott, 2011). Here, strategic leadership is not seen as a new theory, but an element of all educational leadership and management theories (Davies and Davies, 2010). Even so, these concepts can inform and be informed by diverse leadership theories, a strategy-specific framework is needed in the educational field.
Considering all the above, strategy can be identified as a topic that is being researched in education, in the recent decades. Nonetheless, there is still scarce educational literature about this issue Davies and Davies, 2010;Cheng, 2010;Eacott, 2011;Chan, 2018). After 10 years of Eacott's analysis of literature on strategy in education, it seems that this educational construct is being overlooked as there is still no consensual definition of strategy, different studies are supported in diverse conceptual frameworks and empirical studies about this topic are scarce (Cheng, 2010;Eacott, 2011;Chan, 2018). Moreover, despite the interest of a multidisciplinary vision of strategy and strategic leadership, we agree with Eacott (2008b) about the need for a meaningful definition of strategy and strategic leadership in education, as it is a field with its specifications. Hence, research is needed for a clear definition of strategy, an integrated and complete framework for strategic action, a better identification of multiple dimensions of strategy and a comprehensive model of strategic leadership that has strategic thinking and action as core elements for schools improvement (e.g., Eacott, 2010a;Hopkins et al., 2014;Reynolds et al., 2014;Harris et al., 2015;Bellei et al., 2016). This paper aims to contribute to the field offering a scoping review on strategy and strategic leadership in the educational field.
A clear idea of what strategy and strategic leadership mean and what theory or theories support it are of great importance for research and practice. This scoping review is an attempt to contribute to a strategy-specific theory by continuing to focus on ways to appropriately develop specific theories about strategy and strategic leadership in the educational field, particularly focusing on school contexts.

METHODS
This study is a scoping review of the literature related to strategy and strategic leadership, which aims to map its specific aspects as considered in educational literature. Scoping reviews are used to present a broad overview of the evidence about a topic, irrespective of study quality, and are useful when examining emergent areas, to clarify key concepts or to identify gaps in research (e.g., Arksey and O'Malley, 2005;Peters et al., 2015;Tricco et al., 2016). Since in the current study we wanted to explore and categorize, but not evaluate, information available concerning specific aspects of strategy in educational literature, we recognize that scoping review methodology serves well this purpose.
In this study, Arksey and O'Malley (2005) five-stage framework for scoping reviews, complemented by the guidelines of other authors (Levac et al., 2010;Colquhoun et al., 2014;Peters et al., 2015;Khalil et al., 2016), was employed. The five stages of Arksey and O'Malley's framework are 1) identifying the initial research questions, 2) identifying relevant studies, 3) study selection, 4) charting the data, and 5) collating, summarizing and reporting the results. In the sections below, the process of this scoping review is presented.

Identifying the Initial Research Questions
The focus of this review was to explore key aspects of strategy and strategic leadership in educational literature. The primary question that guided this research was: What is known about Frontiers in Education | www.frontiersin.org October 2021 | Volume 6 | Article 706608 strategy and strategic leadership in schools? This question was subdivided into the following questions: How should strategy and strategic leadership in schools be defined? What are the main characteristics of strategic leadership in schools? What key variables are related to strategy and strategic leadership in schools?

Identifying Relevant Studies
As suggested by Arksey and O'Malley (2005), keywords for the search were defined, and databases were selected. Key concepts and search terms were developed to capture literature related to strategy and strategic leadership in schools, considering international perspectives. The linked descriptive key search algorithm that was developed to guide the search is outlined in Table 1.
Considering scoping review characteristics, time and resources available, inclusion and exclusion criteria were developed. Papers related to strategy and strategic leadership, published between 1990 and 2019, were included. Educational literature has reported the concepts of strategy and strategic leadership since the 1980s (Eacott, 2008a;2008b). However, it gained expansion between 1990 and 2000 with studies flourishing mostly about strategic planning (Eacott, 2008b). Previous research argues that strategy is more than planning, taking note of the need to distinguish the concepts. Considering our focus on strategy and strategic leadership, studies about strategic planning were excluded as well as papers specifically related to other theories of leadership than strategic leadership. A full list of inclusion and exclusion criteria is outlined in Table 2.
The following six electronic databases were searched to identify peer-reviewed literature: ERIC, Education Source, Academic Search Complete, Science Direct, Emerland, and Web of Science. Additionally, a manual search of the reference lists of identified articles was undertaken, and Google Scholar was utilized to identify any other primary sources. The review of the literature was completed over 2 months, ending in August 2019.

Study Selection
The process of studies' selection followed the Preferred Reporting of Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement (Moher et al., 2009). Figure 1 illustrates the process of article selection.
With the key search descriptors, 1,193 articles were identified. A further number of articles were identified using Google Scholar. However, a large number of articles were removed from the search, as they were duplicated in databases, and 231 studies were identified as being relevant.
The next phases of studies' selection were guided by the inclusion and exclusion criteria presented above. A screening of the titles, keywords, and abstracts revealed a large number of irrelevant articles, particularly those related to strategic planning (e.g., Agi, 2017) and with general ideas about leadership (e.g., Corral and Gámez, 2010). Only 67 studies were selected for full-text access and analyses.
Full-text versions of the 67 articles were obtained, with each article being reviewed and confirmed as appropriate. This process provided an opportunity to identify any further additional relevant literature from a review of the reference lists of each article (backward reference search; n 2). Ultimately, both with database search and backward reference search, a total of 29 articles were included to be analyzed in the scoping review,

During this process of study selection, several studies were excluded. As in the previous phase, examples of excluded papers include studies related to strategic planning where the focus is on the planning processes (e.g., Bennett et al., 2000;Al-Zboon and Hasan, 2012;Schlebusch and Mokhatle, 2016) or with general ideas about leadership (e.g., FitzGerald and Quiñones, 2018). Additionally, articles that were primarily associated with other topics or related to specific leadership theories (e.g., instructional leadership, transformational leadership) and that only referred briefly to strategic leadership were excluded (e.g., Bandur, 2012;Malin and Hackmann, 2017). Despite the interest of all these topics for strategic action, we were interested specifically in the concepts of strategy, strategic leadership, and its specifications in educational literature.

Data Charting and Collation
The fourth stage of Arksey and O'Malley (2005) scoping review framework consists of charting the selected articles. Summaries were developed for each article related to the author, year, location of the study, participants, study methods, and a brief synthesis of study results related to our research questions. Details of included studies are provided in the table available in Supplementary Appendix S1.

Summarising and Reporting Findings
The fifth and final stage of Arksey and O'Malley (2005) scoping review framework summarises and reports findings as presented in the next section. All the 29 articles were studied carefully and a content analysis was taken to answer research questions. Research questions guided summaries and synthesis of literature content.

RESULTS
In this section, results are presented first with a brief description of the origin and nature of the studies, and then as answering research questions previously defined. This scoping review yielded 29 articles, specifically devoted to strategy and strategic leadership in education, from eleven different countries (cf. Figure 2). The United Kingdom and Australia have the highest numbers of papers. There is a notable dispersion of literature in terms of geographical distribution.
A large number of these articles were published by Brent Davies and colleagues (N 9) and Scott Eacott (N 6). Without question, these authors have influenced and shaped the theoretical grounding about strategy and strategic leadership in educational literature. While Davies and colleagues have contributed to design a framework of strategy and strategic leadership, influencing the emergence of other studies related to these topics, Eacott provided an essential contribution by exploring, systematizing, and problematizing the existing literature about these same issues. The other authors have published between one and two papers about these topics.
Seventeen papers are of conceptual or theoretical nature, and twelve are empirical research papers (quantitative methods-7; qualitative methods-4; mixed methods-1). The conceptual/ theoretical papers analyze the concepts of strategy and strategic leadership, present a framework for strategic leadership, and discuss implications for leaders' actions. The majority of empirical studies are related to the skills, characteristics, and actions of strategic leaders. Other empirical studies explore relations between strategic leadership and other variables, such as collaboration, culture of teaching, organizational learning, and school effectiveness.

How should Strategy and Strategic Leadership in Schools be Defined?
The concept of strategy is relatively new in educational literature and, in great part, related to school planning. In this scoping review, a more integrated and comprehensive view is adopted (Davies, 2003;Davies, 2006;Eacott, 2008a;Eacott, 2008b;Quong and Walker, 2010). Davies (2003) defined strategy as a specific pattern of decisions and actions taken to achieve an organization's goals (p. 295). This concept of strategy entails some specific aspects, mainly that strategy implies a broader view incorporating data about a specific situation or context (Davies, 2003;Dimmock and Walker, 2004;Davies, 2006;Davies, 2007). It is a broad organizational-wide perspective, supported by a vision and direction setting, that conceals longer-term views with short ones (Davies, 2003;Dimmock and Walker, 2004;Davies, 2006;Davies, 2007). It can be seen as a template for short-term action. However, it deals mostly with medium-and longer-term views of three-to 5-year perspectives (Davies, 2003;Davies, 2006;Davies, 2007). In this sense, a strategy is much more a perspective or a way of thinking that frames strategically successful schools (Davies, 2003;Davies and Davies, 2005;Davies, 2006;Davies and Davies, 2010). Eacott (2008a) has argued that strategy in the educational leadership context is a field of practice and application that is of a multidisciplinary or interdisciplinary nature. More than a single definition of strategy, what is needed is a conceptual understanding and articulation of its fundamental features, which removes the need to answer, "what is a strategy?" Understanding strategy as choosing a direction within a given context, through leadership, and articulating that direction through management practices (Eacott, 2008a, p. 356) brings to the arena diverse elements of strategy from both leadership and management. From this alternative point of view, a strategy may be seen as leadership (Eacott, 2010a). More than an answer to "what is a strategy?", it is crucial to understand "when and how does the strategy exist?" (Eacott, 2010a), removing the focus on leaders' behaviors and actions per se to cultural, social, and political relationships (Eacott, 2011). Hence, research strategy and strategic leadership oblige by acknowledging the broader educational, societal, and political contexts (Dimmock and Walker, 2004;Eacott, 2010a;Eacott, 2010b;Eacott, 2011). Strategic leadership is a critical component of school development . However, to define leadership is challenging considering the amount of extensive, diverse literature about this issue. Instead of presenting a new categorization about leadership, the authors most devoted to strategic leadership consider it as a key dimension of any activity of leadership Davies and Davies, 2006;Eacott, 2010a;Eacott, 2010b;Eacott, 2011). Barron et al. (1995) stressed the idea of change. As mentioned by the authors, implementation of strategic leadership means change: change in thinking, change in the way schools are organized, change in management styles, change in the distribution of power, change in teacher education programs, and change in roles of all participants (Barron et al., 1995, p. 180). Strategic leadership is about creating a vision, setting the direction of the school over the medium-to longer-term and translating it into action (Davies and Davies, 2010;Eacott, 2011). In that sense, strategic leadership is a new way of thinking (Barron et al., 1995) that determines a dynamic and iterative process of functioning in schools (Eacott, 2008b).
In their model of strategic leadership, Davies and Davies (2006) consider that leadership must be based on strategic intelligence, summarised as three types of wisdom: 1) people wisdom, which includes participation and sharing information with others, developing creative thinking and motivation, and developing capabilities and competencies within the school; 2) contextual wisdom, which comprises understanding and developing school culture, sharing values and beliefs, developing networks, and understanding external environment; and 3) procedural wisdom, which consists of the continuous cycle of learning, aligning, timing and acting. This model also includes strategic processes and strategic approaches that authors define as the centre of this cycle (Davies and Davies, 2006, p. 136).
To deeply understand strategic leadership, it is necessary to explore strategic processes and approaches that leaders take (Davies and Davies, 2010). In this sense, strategic leadership, strategic processes, and strategic approaches are key elements for sustainable and successful schools, which are found to be strategically focused. Davies (2006) designed a model for a strategically focused school that may be defined as one that is educationally effective in the short-term but also has a clear framework and processes to translate core moral purpose and vision into an excellent educational provision that is challenging and sustainable in the medium-to long-term (p.11). This model incorporates 1) strategic processes (conceptualization, engagement, articulation, and implementation), 2) strategic approaches (strategic planning, emergent strategy, decentralized strategy, and strategic intent), and 3) strategic leadership (organizational abilities and personal characteristics). Based on these different dimensions, strategically focused schools have built-in sustainability, develop set strategic measures to assess their success, are restless, are networked, use multi-approach planning processes, build the strategic architecture of the school, are strategically opportunistic, deploy strategy in timing and abandonment and sustain strategic leadership (Davies, 2004, pp.22-26).
What Are the Main Characteristics of Strategic Leadership in Schools? Davies (2003), Davies and Davies (2005), Davies and Davies (2006), Davies and Davies (2010) discuss what strategic leaders do (organizational abilities) and what characteristics strategic leaders display (personal characteristics). The key activities of strategic leaders, or organizational abilities, are 1) create a vision and setting a direction, 2) translate strategy into action, 3) influence and develop staff to deliver the strategy, 4) balance the strategic and the operational, 5) determine effective intervention points (what, how, when, what not to do and what to give up), 6) develop strategic capabilities, and 7) define measures of success Davies and Davies, 2010). The main characteristics that strategic leaders display, or their characteristics, are 1) dissatisfaction or restlessness with the present, 2) absorptive capacity, 3) adaptive capacity, and 4) wisdom.
Two specific studies explored the strategic leadership characteristics of Malaysian leaders (Ali, 2012;Ali, 2018), considering the above-mentioned model as a framework. For Malaysian Quality National Primary School Leaders, the results supported three organizational capabilities (strategic orientation, translation, and alignment) and three individual characteristics of strategic leadership (dissatisfaction or restlessness with the present, absorptive capacity, and adaptive capacity). For Malaysian vocational college educational leaders, the results were consistent with seven distinct practices of strategic leadership, such as strategic orientation, strategic alignment, strategic intervention, restlessness, absorptive capacity, adaptive capacity, and leadership wisdom.
Other studies were also focused on the characteristics of strategic leadership with different populations and countries. Chatchawaphun et al. (2016) identified the principles, attributes, and skills of the strategic leadership of secondary school administrators from Thailand. The principles identified within the sample of principals included appropriate values, modern visionary, future focusing strategy, empirical evidence focus, intention toward accomplishment, decency, and making relationships. The attributes found were strategic learning, strategic thinking, and value push up. The skills were learning, interpretation, forecasting, planning, challenge, and decision making. Chan (2018)  education and identified effective planning and management, reflective and flexible thinking, and networking and professional development as variables. Eacott (2010c) investigated the strategic role of Australian public primary school principals concerning the leader characteristics of tenure (referring to the time in years in their current substantive position) and functional track (referring to the time in years spent at different levels of the organizational hierarchy). These demographic variables have moderating effects on the strategic leadership and management of participants. These five studies seem to be outstanding contributions to solidify a framework of strategic leadership and to test it with different populations in different countries. Additionally, Quong and Walker (2010) present seven principles for effective and successful strategic leaders. Strategic leaders are future-oriented and have a future strategy, their practices are evidence-based and research-led, they get things done, open new horizons, are fit to lead, make good partners and do the "next" right thing-these seven principles of action seem related to the proposal of Davies and colleagues. Both authors highlighted visions for the future, future long-term plans, and plans' translation into action as important characteristics of strategic leaders.
One other dimension that is being explored in research relates to ethics. Several authors assert that insufficient attention and research have been given to aspects related to moral or ethical leadership among school leaders (Glanz, 2010;Quong and Walker, 2010;Kangaslahti, 2012). The seventh principle of the Quong and Walker (2010) model of strategic leadership is that leaders do the "next" right thing. This relates to the ethical dimension of leadership, meaning that strategic leaders recognize the importance of ethical behaviors and act accordingly. For some authors, ethics in strategic leadership is a critical issue for researchers and practitioners that needs to be taken into consideration (Glanz, 2010;Quong and Walker, 2010). Glanz (2010) underlined social justice and caring perspectives as required to frame strategic initiatives. Kangaslahti (2012) analyzed the strategic dilemmas that leaders face in educational settings (e.g., top-down strategy vs. bottom-up strategy process; leadership by authority vs. staff empowerment; focus on administration vs. focus on pedagogy; secret planning and decision making vs. open, transparent organization; the well-being of pupils vs. well-being of staff) and how they can be tackled by dilemma reconciliation. Chen (2008), in case study research, explored the conflicts that school administrators have confronted in facilitating school reform in Taiwan. The author identified four themes related to strategic leadership in coping with the conflicts accompanying this school reform: 1) educational values, 2) timeframe for change, 3) capacity building, and 4) community involvement. These studies reinforce the idea that school improvement and success seem to be influenced by the way leaders think strategically and deal with conflicts or dilemmas. Researchers need to design ethical frameworks or models from which practitioners can think ethically about their strategic initiatives and their dilemmas or conflicts (Chen, 2008;Glanz, 2010;Kangaslahti, 2012).
Despite the critical contribution of Davies' models (Davies, 2003;Davies, 2004;Davies and Davies, 2006;Davies and Davies, 2010) and subsequent works, Eacott (2010a) questions the production of lists of behaviors and traits. This is likely one of the main differences between Davies' and Eacott's contributions in this field. While Davies and colleagues include organizational abilities and personal characteristics in their model of strategic leadership, Eacott (2010aEacott ( , 2010b emphasizes the broader context where strategy occurs. These ideas, however, are not contradictory but complementary in the comprehension of strategy as leadership in education since both authors present a comprehensive and integrated model of strategic leadership. Even though Davies and colleagues present some specific characteristics of leaders, these characteristics are incorporated into a large model for strategy in schools.

What Are Other Key Variables Related to Strategy and Strategic Leadership in Schools?
Other studies investigated the relationship between strategic leadership and other key variables, such as collaboration (Ismail et al., 2018), the culture of teaching (Khumalo, 2018), organizational learning (Aydin et al., 2015) and school effectiveness (Prasertcharoensuk and Tang, 2017).
One descriptive survey study presented teacher collaboration as a mediator of strategic leadership and teaching quality (Ismail et al., 2018). The authors argue that school leaders who demonstrate strategic leadership practices can lead to the creation of collaborative practices among teachers and thus help to improve the professional standards among them, namely, teaching quality (Ismail et al., 2018). One crosssectional study identified positive and significant relations among the variables of strategic leadership actions and organizational learning. Transforming, political, and ethical leadership actions were identified as significant predictors of organizational learning. However, managing actions were not found to be a significant predictor (Aydin et al., 2015). One other study establishes that strategic leadership practices promote a teaching culture defined as the commitment through quality teaching for learning outcomes (Khumalo, 2018). These three studies provide essential highlights of the relevance of strategic leadership for school improvement and quality. Nonetheless, it is interesting to note that in a research survey that examined the effect of leadership factors of administrators on school effectiveness, the authors concluded that the direct, indirect, and overall effects of the administrators' strategic leadership had no significant impact on school effectiveness (Prasertcharoensuk and Tang, 2017). These studies introduce important questions that need to be explored both related to strategy and strategic leadership features and its relations and impacts on relevant school variables. Such studies stimulate researchers to explore these and other factors that relate to strategic leadership.

DISCUSSION
The knowledge about strategy and strategic leadership is still incomplete and confusing (Eacott, 2008a;Eacott, 2008b). From the 29 studies selected, divergent data and multiple concepts of strategy can be identified which reinforces the confusion about these issues. Some integrative clarification is still needed about the Frontiers in Education | www.frontiersin.org October 2021 | Volume 6 | Article 706608 concepts of strategy and strategic leadership as about its core features. In this section, it is intended to contribute to the clarification and integration of the concepts considering the studies selected. The emergence of politics and reforms related to school autonomy and responsibility in terms of efficacy and accountability brings the concept of strategy to the educational literature (Eacott, 2008b;Cheng, 2010). It first appeared in the 1980s but gained momentum between 1990 and 2000. However, the main focus of the literature was on strategic planning based upon mechanistic or technical-rational models of strategy. Authors have criticized the conceptualization of strategy as a way for elaborating a specific plan of action for schools (Davies, 2003;Davies, 2006;Eacott, 2008a;Eacott, 2008b;Quong and Walker, 2010). These same authors adopted a more comprehensive and holistic model of strategy. The concepts have been developed from a more rational and mechanistic view related to planning processes to a more comprehensive and complex view of strategy and leadership that take into consideration a situated and contextual framework. Considering the contribution of these studies, strategy incorporates three core dimensions, articulated with a schoolwide perspective 1) Vision, mission and direction (e.g., Davies, 2003;Dimmock and Walker, 2004;Davies, 2006;Davies and Davies, 2006;Davies, 2007;Eacott, 2008a) 2) Intentional thinking (e.g., Barron et al., 1995;Davies, 2003;Davies and Davies, 2005;Davies, 2006;Davies and Davies, 2010): and; 3) Articulated decision-making and action (e.g., Davies, 2003;Dimmock and Walker, 2004;Davies and Davies, 2006;Davies, 2006;Davies, 2007;Eacott, 2008a;Eacott, 2010a;Eacott, 2010b;Eacott, 2011).
Strategic leaders have an important role in strategy but, even considering this comprehensive and holistic concept of strategy, research poses the question of what are the main characteristics of strategic leaders in schools? From the literature reviewed, specific abilities, behaviors, and other characteristics may be identified. Looking for an integrated picture of strategic leadership, Table 3 represents the main contributions of the studies selected.
Despite the contribution of these studies to deep knowledge about strategic leadership, the discussion here considers whether it is worthwhile to produce lists of behaviors and traits for strategic leaders in the absence of an integrated model that acknowledges the broader educational, societal and political context (Dimmock and Walker, 2004;Eacott, 2010a;Eacott, 2010b;Eacott, 2011). Eacott (2011) argues that strategy, as constructed through analysis, is decontextualized and dehumanized and essentially a vacuous concept with limited utility to the practice that it seeks to explain (p. 426). Without a comprehensive and contextual model of strategy and strategic leadership, supported by research, the topics may still be overlooked and misunderstood. With this in mind, Figure 3 attempts to represent the core dimensions of strategy from a comprehensive perspective.
As this is a scoping review, we tried to display a general view of the literature that can serve as a basis for a specific strategy theory in education and to more in-depth studies related to strategy and strategic leadership in schools. Nevertheless, we need to identify FIGURE 3 | Strategy and core dimensions from a comprehensive perspective.

As a scoping review, methods and reporting need improvement (Tricco et al., 2018) and we are aware of this circumstance. Also, our search strategy may have overlooked some existing studies, since grey documents (e.g., reports) and studies from diverse languages than English were not included, that can misrepresent important data. Besides, inclusion criteria focused only on studies specifically devoted to strategy (not strategic planning) and strategic leadership (no other theories of leadership), but we acknowledge important contributions from this specific literature that were excluded. Finally, in our study there is no comparative analysis between the western and eastern/oriental contexts. However, we are aware that these contexts really differ and a context-specific reflection on strategy and strategic leadership in education would be useful. More research is needed to overcome the limitations mentioned. Besides, the pandemic COVID19 brought new challenges in education, and particularly, to leaders. This study occurred before the pandemic and this condition was not acknowledged. However, much has changed in education as a consequence of the pandemic control measures, these changes vary from country to country, and schools' strategies have changed for sure. Future research needs to explore strategy and strategic leadership in education considering a new era post pandemic.

CONCLUSION
With this scoping review, the authors aimed to contribute to enduring theories about strategy and strategic leadership in education. From our findings, it appears that this issue is being little explored. Despite the important contributions of authors cited in this scoping review (Aydin et al., 2015;Chatchawaphun et al., 2016;Prasertcharoensuk and Tang, 2017;Ali, 2018;Chan, 2018;Ismail et al., 2018;Khumalo, 2018), minor advances seem to have been made after 2010. This is intriguing taking into account the leaders' role in the third wave of educational reform, where strategic leadership pursues a new vision and new aims for education due to maximizing learning opportunities for students through "triplisation in education' (i.e., as an integrative process of globalization, localization and individualization in education)" (Cheng, 2010, p. 48). It was expected that research moved from rational planning models towards a more complex view of strategy in education (Eacott, 2011). This review brings the idea that some timid and situated steps have been made.
Since the important review by Eacott, published in 2008, a step forward was made in the distinction between strategy and planning. Despite the significant number of papers about planning that were found during this review, the majority were published before 2008 (e.g., Nebgen, 1990;Broadhead et al., 1998;Bennett et al., 2000;Beach and Lindahl, 2004;Bell, 2004). Also, most of the papers selected adopt a more integrative, comprehensive, and complex view of strategy and strategic leadership (e.g., Eacott, 2010a;Eacott, 2010b;Davies and Davies, 2010;Eacott, 2011;Ali, 2012;Ali, 2018;Chan, 2018). More than identifying the "best of" strategy and strategic leadership, alternative models understand strategy as a way of thinking (Davies and Davies, 2010) and a work in progress (Eacott, 2011).
This also resonates with the educational literature about loosely coupled systems. There is evidence that loosely coupled educational organizations continue to exist and that resistance to change is a characteristic of school organizations (Hautala et al., 2018). Strategic leadership gains relevance since leaders need to consider how to manage their loose and tight configurations and, hence, reinforce simultaneous personal and organizational dimensions related to school improvement. It is time to expand the research into more complex, longitudinal, and explanatory ways due to a better understanding of the constructs. This scoping review was an attempt to contribute to this endeavor by integrating and systematizing educational literature about strategy and strategic leadership.
