The last two decades have seen the growing adoption of mobile devices to enhance the quality of teachers' continuous professional development (TCPD) in low-income countries. Using mobile devices, typically not designed for educational use, presents new usability challenges, preventing teachers from effectively accessing learning materials in…

Many recent studies document the difficulties that students experience when learning organic chemistry, often due to the complex visualization and reasoning skills required to successfully understand the ways molecules interact in specific environments. Many of these studies call on instructors to improve their teaching strategies to support…

Measures of teacher mathematical knowledge are notoriously difficult to develop (e.g., Orrill et al., 2015). This is in part because of the multidimensional nature of teacher knowledge. As part of two separate projects being undertaken by this research team, we have attempted to write assessments of teacher pedagogical content knowledge (PCK) in…

In this paper, we extend our previous work on challenges teachers face when engaging with proportional reasoning contexts to investigate two contexts that included four problems for middle grades teachers to solve as well as eight student solutions. Analysis included coding for correct solving of the problem as well as making sense of and…

Recent research on learning analytics dashboards has focused on designing user interfaces that offer various forms of "visualization guidance" (often referring to notions such as "data storytelling" or "narrative visualization") to teachers (e.g., emphasizing data points or trends with colour and adding annotations),…

The purpose of this case study was to describe how one band director used pedagogical content knowledge while working with beginning-band students to help them develop the skill of playing brass lip slurs. Data were generated from (1) video recordings of each class over two different weeks during the school year, (2) "think aloud"…

Self-service design tools are flooding K-12 environments and altering the way instruction can be designed and delivered. As a result, schools are utilizing existing academics to both design and teach their own curriculum. These academics, called "designers-by-assignment", tend to have limited training in instructional systems design and…

This thesis explores the role of multiple representations in introductory physics students' problem solving performance through several investigations. Representations can help students focus on the conceptual aspects of physics and play a major role in effective problem solving. Diagrammatic representations can play a particularly important role…

The World Bank 2007 TIMSS Video Study provided a distinctive insight into the practices of the Indonesian classroom and identified key strengths and weaknesses of current teaching. This investigation considered this evidence in the development of a structured lesson design that specifically addressed the instructional practices of the teaching and…

The purpose of this research was to investigate instructional conditions aimed at improving future teachers' reflective thinking, to systematically trace how features of a guided instructional procedure influenced these teachers' pedagogical reasoning. The reflective thinking protocol that formed the basis of the instructional approach was built…

This investigation examined the influence of EFL student teacher self-regulation of learning (SRL) on their curricular content-knowledge and course-design skills. Positivism guided this study at the levels of: ontology (one form of reality); epistemology (detachment from the subjects); and methodology, using nomothetic research strategy (causal…

In this study, we explore the instructional decision making of Charlotte, a graduate of an intensive social studies teacher education program. Charlotte articulated a sophisticated conception of historical thinking and appeared to possess exemplary pedagogical content knowledge. Her classroom practice did not incorporate the approaches to…
