Assessments play a pivotal role in Mathematics education, serving as vital gauges of students' mathematical proficiency and informing teaching strategies. Despite calls for contextualization, some educators still rely on abstract teaching methods and decontextualized tasks. This study aims to address these concerns by designing and implementing a…

Research on self-regulated learning (SRL) in engineering design is growing. While SRL is an effective way of learning, however, not all learners can regulate themselves successfully. There is a lack of research regarding how student characteristics, such as science knowledge and design knowledge, interact with SRL. Adapting the SRL theory in the…

Background: Video lectures which include the teachers' presence have become increasingly common. As teacher enthusiasm is a nonverbal cue in video lectures, more and more studies are focusing on this topic. However, little research has been carried out on the interactions between teacher enthusiasm and prior knowledge when learning from video…

While the use of experiments is important for developing students' scientific knowledge and skills, challenges may arise when teachers and students are conducting experiments in class, such as non-reusable experimental resources, safety issues and difficulties simulating some specific effects. Augmented reality (AR) technology affords an…

Purpose: Guided by the cognitive load theory, the purpose of this study was to determine the impacts of cognitive load and school socioeconomic status-related environmental factors on ninth-graders' energy-balanced living knowledge gain. Methods: A stratified random sample of high-school students (N = 150) participated in this study. Data were…

Schematic chunks denote patterns, schemes, or sophisticated rules and knowledge stored in the long-term memory in the form of chunks. We investigated whether schematic chunking is effective in improving the performance of students with math difficulties (MD) and students at risk of math failure, and how the complexity level of geometry problems…

The purpose of this research is to better understand the uses and potential of triadic dialogue (initiation-response-feedback) as a dominant discourse pattern in test-driven environments. We used a Bakhtinian dialogic perspective to analyze interactions among high-stakes tests and triadic dialogue. Specifically, the study investigated (a) the…

A clearly stated lesson objective is considered an essential component of a well-planned lesson. Many teachers of Technology, a relatively new subject in South African schools, teach Technology with rather limited training both in content and methodological approaches. This study sought to investigate and classify lesson objectives framed or…

Despite the general effectiveness of multimedia instruction, students do not always benefit from it. This study examined whether students' learning from multimedia can be improved by teaching them relevant learning strategies. On the basis of current theories and research on multimedia learning, the authors developed a strategy training for…

Research has demonstrated that instruction that relies heavily on studying worked examples is more effective for less experienced learners compared to instruction emphasizing problem solving. However, the guidance associated with studying some worked examples may reduce the performance of more experienced learners. This study investigated…

The authors outline results of 3 studies conducted to examine the structure of disciplinary knowledge from reading measured through proximity data. In Study 1, 168 third-grade students were asked to read a science text and rate the relationships of keywords from the passage. From these ratings, comprehension scores were calculated that related…

This paper examines the images middle school students have of science and technology, the workplaces, and the relevant professions. It also describes the effect on these images caused by an instructional initiative, "Investigation into Science and Technology" (IST), designed to introduce students to science and technology in the "real life."…
