This design-based research study investigates the development of pedagogical content knowledge among nine teacher-participants (N = 9) in three design phases. PCK is a particular type of teacher knowledge that addresses not only the teacher’s understanding of the content to be instructed, but also ways of how to teach that content effectively. This knowledge has been well documented over several decades, and is seen as central to teacher expertise. However, its actual development has been difficult for researchers to investigate. This study offers a detailed perspective on how teachers developed PCK with their engagement in lesson planning and enactment of a project-based technology-enhanced lesson. The study includes two specific interventions designed to enhance teachers’ development of PCK: (1) scaffolded reflection that occurs throughout the practices; and (2) peer-exchange of lesson plans, enactment ideas, and completed reflections. The findings demonstrate that teachers improve their planning and enactment of project-based technology-enhanced lessons with scaffolded reflection and peer exchange. Positive correlations were seen between teachers’ engagement in the reflections and the quality of their lesson planning. Teachers who participated more deeply in the scaffolded reflections were able to understand how their lesson plans and enactment patterns fostered student understanding of relevant science concepts. Positive correlations were also seen between community influence and teacher lesson plans and enactment. Additionally, positive correlations were confirmed between teachers’ level of participation in the peer exchange activities and the quality of their lesson planning and enactments. Teachers who contributed more deeply within the online and face-to-face peer community meetings benefited from the different perspectives of their peers about student learning and the best ways to succeed with project-based instruction. This study allowed some insight into how PCK develops as a result of teachers’ engagement in the complex set of activities that constitute the practices of lesson planning and enactment. The primary implication of this study is that engaging teachers in scaffolded reflections and peer exchange can be a valuable in-service professional development activity. A methodological strength is derived from an approach to coding teachers’ lesson planning and enactment according to an activity systems perspective, drawing on a spectrum of data sources (e.g., wiki-based reflections, planning artefacts, videotaped classroom enactments). Teacher learning—particularly the development of PCK—is recognized as critical in promoting student understanding of science concepts. This dissertation lays out a possible foundation for professional development models that promote effective teacher learning.

This design-based study was the first empirical investigation of a new model of learning and instruction called Knowledge Community and Inquiry (KCI). In KCI, students are engaged as a learning community as they work on scaffolded inquiry activities that target specific science learning objectives. Although community-oriented approaches have been successful at the elementary level, there has been relatively little uptake of such methods at the secondary school level – particularly in science. The pedagogical framework of KCI addresses the challenges of community models by blending established inquiry based approaches with community-oriented pedagogy. This dissertation tested the validity of KCI by designing, implementing, and empirically evaluating a curriculum based on the KCI model. This was achieved through curriculum trials involving two separate cohorts of grade-ten biology students (n = 102; n = 112). The first implementation consisted of a two-week physiology lesson that engaged students in co-authoring wiki artifacts about human system diseases, which students then used as a resource for solving medical case studies. The second implementation, an eight-week lesson on Canada's biodiversity, was a deeper application of the model, and focused on students' collaborative processes during the construction of their wiki-based knowledge repository. In both cases, the curriculum was evaluated according to its design, enactment, and learning outputs, as evidenced by students' knowledge artifacts and performance on the final exam. Technology scaffolds ensured that students focused on the physiology and biodiversity science curriculum expectations. Analyses of the data revealed that KCI engaged students in collaborative learning processes that were characteristic of a knowledge community. Additionally, final exam scores demonstrated increased learning performance when compared to those from previous years where students did not participate in KCI. The findings from this research provide the first empirical support for KCI, and demonstrate its potential for engaging secondary science students in the kinds of collaborative inquiry processes of authentic knowledge communities. This dissertation provides insight into the conditions necessary for such engagement, and contributes design recommendations for blending knowledge community and inquiry in secondary school science curriculum.

An engaging education attends to the subjective quality of students’ perceptions and experiences within learning and school life: It converges on whether, how, and why students meaning-make and belong within the school; and focuses on the conditions for their attachment, participation, and commitment within school programmes, practices, policies, and people. Three main questions guided this two-phase, mixed-methods study: 1) What makes international schools engaging places for students? 2) What meanings do students attach to key areas of their day-to-day experiences within the international school in Hong Kong? 3) How might re-imagining student engagement through a cosmopolitan lens lead to clearer understandings of students’ experiences within the international school? In Phase 1, an achieved sample of 729 senior secondary students at 9 purposively selected schools were surveyed using a mainly Likert scale questionnaire: to describe their socio-demographics; to examine the relationships between their socio-demographics, attitudinal features, and schooling experiences, as measured by the researcher-designed Experience of International School – Revised (EIS-R) scale; and to cluster using their socio-demographics and attitudinal profiles. Building on the tripartite cluster solution, Phase 2 used observations and interviews with 30 purposively sampled teacher-leaders and 34 students, from across the three clusters, to investigate how the “institutional habitus” (Thomas, 2002) the students encountered at two international schools shaped their experiences of and engagement within the contexts of school culture, community, curriculum, and co-curriculum. A two-stage process of thematic content analysis revealed two super ordinate themes: 1) race/ethnic, linguistic, and nationality identities intersected to shape and challenge patterns of relationships amongst students (and between students/families) and the school to both include and exclude; and 2) the institutional contexts supported and constrained students’ sense of belonging therein. Overall, seen through a cosmopolitan lens the study implications are discussed as three lessons to achieve a better fit between students and the international school: 1) Attend to the school’s living and learning environment; 2) Take a cosmopolitan turn to school for cosmopolitan subjectivity; and 3) Adopt a student engagement-driven approach to improve and reform school policy, administration, and practice.

The purpose of this study was to explore how students with learning disabilities understood and experienced their transition from high school to postsecondary education. In-depth interviews with 7 graduates of Achievement School (pseudonym), a private high school for students with learning disabilities in the southwestern region of the United States, were conducted to elicit personal narratives of students’ transition experiences from high school to college. By doing so, findings contribute to a deeper understanding of students’ experiences and what allows students with learning disabilities to succeed in their transition to university or college. In addition, 4 parents and 4 high school staff members were interviewed for this study to provide a triangulated perspective on the experience studied. Few studies have collected and analyzed the perceptions and voices of students with learning disabilities as they transition to postsecondary education. This study provides insight towards bridging the gap in providing further insight into the students with learning disabilities’ experiences on their transition to college and the factors students’ feel have impeded or supported their success in this new environment. This study utilized a descriptive and phenomenological qualitative research methodology consisting of individual in-depth interviews with the students and member checks with informants, their parents, and staff members of the participants’ former high school. Suggestions will be made for future research as well as for practical application for future students as well as high school and postsecondary service providers.

New programming, such as the Specialist High Skills Major has been implemented in Ontario as part of the Student Success Learning to 18 Strategy to increase secondary graduation rates. Yet it has been unclear if this type of programming is actually improving student outcomes. As a result, this study asks: How does the implementation of the Specialist High Skills Majors (SHSM) contribute to student outcomes? Sub-research questions inquire about the consistency of the SHSM across Ontario, which students the SHSM has the greatest impact on academic success and if participation in the SHSM increases students’ academic success as defined by credit accumulation, marks, and graduation. The conceptual framework in this study is an amended version of Fullan’s (2007) critical factors that affect policy implementation. The study’s methods first included reviewing Ontario School Information System data on student achievement in the SHSM program. Interviews with thirty-four people also took place in eight schools from a mix of four geographically diverse Catholic and public school districts in Ontario that had high student enrollment in the SHSM program. While there were many findings within this study, four were key. The first finding was that there was great consistency to some aspects of implementing the SHSM program province-wide when there was top-down direction, while there was also great variability in other areas where there was increased flexibility. The second key finding centers around the role of leadership, including effective styles of leadership, consistency in leadership, and the importance of delegating leadership responsibility. The third finding highlights the importance of resources in implementing change. The last finding discusses the type of SHSM student that is most successful in the SHSM program and how program implementation directly affects student success.

This thesis examines the role of epistemic cognition within the context of a Knowledge Community and Inquiry (KCI) curriculum for secondary science. The study employs a new form of design-based research, called Model-Based Design Research (MBDR), which first maps a formal pedagogical model onto the curriculum design, and then assesses how the enacted curriculum adheres to the design. The curriculum design was a ten-week Grade 11 Biology unit that met the Ontario Ministry requirements for evolution and biodiversity, and included activities situated within a unique immersive environment called EvoRoom. The thesis includes an assessment of students' epistemological views about science and science learning, and evaluates the epistemic commitments of KCI using a relevant theoretical framework of epistemic cognition. The analysis reveals the complex interconnections amongst the epistemological, pedagogical and technological elements of the design, resulting in recommendations for future design iterations as well as theoretical insights concerning the KCI model.

This study investigated secondary school students’ errors and misconceptions in algebra with a view to expose the nature and origin of those errors and to make suggestions for classroom teaching. The study used a mixed method research design. An algebra test which was pilot-tested for its validity and reliability was given to a sample of grade 11 students in an urban secondary school in Ontario. The test contained questions from four main areas of algebra: variables, algebraic expressions, equations, and word problems. A rubric containing the observed errors was prepared for each conceptual area. Two weeks after the test, six students were interviewed to identify their misconceptions and their reasoning. In the interview process, students were asked to explain their thinking while they were doing the same problems again. Some prompting questions were asked to facilitate this process and to clarify more about students’ claims. The results indicated a number of error categories under each area. Some errors emanated from misconceptions. Under variables, the main reason for misconceptions was the lack of understanding of the basic concept of the variable in different contexts. The abstract structure of algebraic expressions posed many problems to students such as understanding or manipulating them according to accepted rules, procedures, or algorithms. Inadequate understanding of the uses of the equal sign and its properties when it is used in an equation was a major problem that hindered solving equations correctly. The main difficulty in word problems was translating them from natural language to algebraic language. Students used guessing or trial and error methods extensively in solving word problems. Some other difficulties for students which are non-algebraic in nature were also found in this study. Some of these features were: unstable conceptual models, haphazard reasoning, lack of arithmetic skills, lack or non-use of metacognitive skills, and test anxiety. Having the correct conceptual (why), procedural (how), declarative (what), and conditional knowledge (when) based on the stage of the problem solving process will allow students to avoid many errors and misconceptions. Conducting individual interviews in classroom situations is important not only to identify errors and misconceptions but also to recognize individual differences.
