Graphing calculators are hand-held technological tools currently used in mathematics classrooms. Teachers' perspectives on using graphing calculators are important in terms of exploring what teachers think about using such technology in advanced mathematics courses, particularly precalculus courses. A descriptive intrinsic case study was conducted…

This ethnographic case study problematizes the current high stakes accountability efforts that have led many school leaders to inadvertently maintain a school environment in which deficit perspectives and low academic expectations in the classroom persist. Drawing from an urban sanctuary school framework, this study works to center the voices of…

The aim of this study is to analyze the effect of meaning making based instruction regarding angular momentum conservation on the change of two 11th grade students' alternative ideas they have before instruction. Case study model is used in the research. Conceptual test (implemented before the instruction, right after the instruction and fifteen…

This study focuses on teacher's Knowledge for Teaching Mathematics with Technology (KTMT), paying a special attention to teacher's representational fluency. It intends to characterize how the teacher uses and integrates the different representations provided by the graphing calculator on the process of teaching and learning functions at the high…

In this paper I describe and analyse how critical pedagogy, an approach to teaching and learning that encourages students to reflect on their socio-political contexts, may stimulate critical consciousness and dialogue at a youth radio show. The participants, who attended four diverse Cape Town high schools and predominantly lived in poor…

We examined the interactions among pedagogical content knowledge (PCK) components of novice and experienced chemistry teachers in teaching reaction rate and chemical equilibrium topics in this qualitative multiple-case design study. For this aim, three chemistry teachers who had different levels of teaching experience in chemistry teaching were…

In this article, we report the findings of a qualitative, collective case study exploring the academic experiences of six grade 11 gifted students in two schools in diverse socio-economic communities in rural Western South Africa. Gifted students represent an important component of a nation's intellectual capital. They possess the qualities needed…

Creating effective pathways for students to transition from high school to college or career is immensely important and, although challenging, some have developed promising approaches. This case study examined how formal and informal leaders in an urban high school and district collaborated to implement a college and career academy model,…

This study examined a linkage program between a secondary school and a community college in Ontario, Canada. The study sought to identify (a) appropriate success criteria to evaluate a high school-community college program and (b) the attributes that promote or ensure a program's sustainability. Though initially successful, the investigated…

The learning sciences community has made significant progress in understanding how people think and learn about complex systems. But less is known about how people make sense of the quantitative patterns and mathematical formalisms often used to study these systems. In this article, we make a case for attending to and supporting connections…

This article examines the discursive positions South African high school students take up in response to a teaching intervention that invites them to historicize their identities. It thus seeks to contribute to the growing body of education research on how to meaningfully engage young people in post-conflict societies with their recent past.…

The purpose of this study was to understand how students utilized multiple representations to learn and explain science concepts, in this case the human breathing mechanism. The study was conducted with Grade 11 students in a human biology class. Semistructured interviews and a two-tier diagnostic test were administered to evaluate students'…

The paper explores conceptions of the nature of scientific inquiry (NOSI) held by five teachers who were purposively and conveniently sampled. Teachers' conceptions of the NOSI were determined using a Probes questionnaire. To confirm teachers' responses, a semi-structured interview was conducted with each teacher. The Probes questionnaire was…

This study explored the pedagogical content knowledge (PCK) and its development of four experienced biology teachers in the context of teaching school genetics. PCK was defined in terms of teacher content knowledge, pedagogical knowledge and knowledge of students' preconceptions and learning difficulties. Data sources of teacher knowledge base…

This paper concerns an exploratory and interpretive case study of the literacy curricula in a Canadian transnational education programme (Pseudonym: SCS) delivered in China where Ontario secondary school curricula were used at the same time as the Chinese national high school curricula. Using ethnographic tools and actor-network theory, the study…
