To efficiently create books and other instructional content from videos and further improve accessibility of our course content we needed to solve the scene detection (SD) problem for engineering educational content. We present the pedagogical applications of extracting video images for the purposes of digital book generation and other shareable…

The aim of this article was to find the connections between teachers' actions (N = 7) and their 3rd graders' performances (N = 86) when solving an open problem. A lot of information about the teaching sessions was gathered by video recordings and collecting pupils' solutions. Teachers' actions were analysed carefully through the phases of a…

Contemporary curriculum demands the development of both problem solving skills and negotiative skills required for collaborative group work. Tasks are required that create the best possible conditions for students to develop both of these skill sets. Open-ended tasks have been shown to provide these conditions, but they also require the teacher to…

In this paper, we explore the relationship between scaffolding, dialogue, and conceptual breakthroughs, using data from a design-based research study that focuses on the development of understanding of probability in 10-12 year old students. The aim of the study is to gain insight into how the combination of scaffolding for content using…

This paper describes the outcomes of a qualitative investigation into the range of different approaches that students use to solve open-ended, context rich problems. The study involved a small cohort of students individually solving open-ended, context-rich problems using a think aloud protocol. The problems required the students to develop a…

In the past three decades, researchers have noted the limitations of a problem-solving approach that overemphasizes algorithms and quantitation and neglects student misconceptions and an otherwise qualitative, conceptual understanding of chemical phenomena. Since then, studies and lessons designed to improve student understanding of chemistry has…

Subtraction has two meanings and each meaning leads to the different strategies. The meaning of "taking away something" suggests a direct subtraction, while the meaning of "determining the difference between two numbers" is more likely to be modeled as indirect addition. Many prior researches found that the second meaning and…

While a body of research exists on individual metacognition, research on reflective communities is just beginning. This study generated a framework for conceptualizing metacognition in groups by describing likely components of group metacognition. I focused on a group of five preservice science teachers engaged in problem-based learning (PBL). The…

Previous research shows that speed is one of the most difficult in the upper grades of primary school. It is because students must take into consideration two variables; distance and time. Nevertheless, Indonesian students usually learn this concept as a transmission subject and teacher more emphasizes on formal mathematics in which the concept of…
