There has been much attention given to the use of technology in education; mostly concentrating on physical artifacts of technology to facilitate teaching delivery but little mentioning technology as a cultural resource to organize the learning environment promoting social interaction among students and between teacher and students. This paper…

Instructional strategies that support meaningful student learning of complex chemical topics are an important aspect of improving chemistry education. Adequately assessing the success of these approaches can be supported with the use of aligned instruments with established psychometrics. Here, we report the implementation and assessment of one…

This study reports an analysis of how pre-service teachers (n=34) made sense of fraction division with remainders using pictorial modeling strategies, and how small-group and whole-class discussion helped them develop conceptual understanding. One and a half class sessions were video recorded, and 12 interviews were conducted. Results indicate…

Although spatial reasoning and penetrative thinking skills are essential for many disciplines, these concepts are difficult for students to comprehend. In microscopy, traditional educational materials (i.e., photographs) are static. Conversely, video-based training methods convey dimensionality. We implemented a real-time digital video imaging…

This article examines prospective elementary teachers' conceptions of unitizing with whole numbers and fraction concepts and operations throughout a semester-long mathematics content course. Student work samples and classroom conversations are used to illustrate the types of unitizing understandings that prospective teachers bring to teacher…

In this paper, we report a teaching experiment regarding the theory of polynomial approximations at the university mathematics teaching in Sweden. The experiment was designed by applying Variation theory and by using the free dynamic mathematics software GeoGebra. The aim of this study was to investigate if the technology-assisted teaching of…

Students should learn mathematics with understanding. This is one of the ideas in the literature on mathematics education that everyone supports, from educational politicians to curriculum developers, from researchers to teachers, and from parents to students. In order to decide whether or not students understand mathematics we should first…

Comparing multiple solutions to a single problem is an important mode for developing flexible mathematical thinking, yet instructionally leading this activity is challenging (Stein, Engle, Smith, & Hughes, 2008). We test 1 decision teachers must make after having students solve a problem: whether to only verbally discuss students' solutions or…

The study aimed to examine the effect of explicit reading instruction as an approach to Concept-Oriented Reading Instruction (CORI) framework on EFL students' informational text comprehension and engagement. The explicit reading instruction was implemented with 39 first-year Thai undergraduate students over a 10-week period. It was found that the…

Beyond common associated factors, such as teacher characteristics and socioeconomic background of students, little is known about how student achievement relates to differences in the pedagogical approaches used in Latin American classrooms. This paper highlights the main findings from a qualitative study on cross-country differences in teaching…

Demonstrations can be very effective at enhancing student learning and represent a mechanism for embedding laboratory experiences within a classroom setting. A key component to an effective demonstration is active student engagement throughout the entire process, leading to a guided laboratory experience in a lecture setting. Students are involved…
