We present a study of active learning pedagogies in an upper-division physics course. This work was guided by the principle of deliberate practice for the development of expertise, and this principle was used in the design of the materials and the orchestration of the classroom activities of the students. We present our process for efficiently…

This research explored how different models of Web-based dynamic assessment in remedial teaching improved junior high school student learning achievement and their misconceptions about the topic of "Weather and Climate." This research adopted a quasi-experimental design. A total of 58 7th graders participated in this research.…

In spite of the commendations for the use of portfolio assessment, there is still little evidence indicating that such assessment actually supports and encourages student learning. Hence, this research study aimed to empirically identify the effects of implementation of portfolio assessment on student learning and attitudes. True-experimental…

This quasi-experimental study investigated how explicit instruction about multiple modes of representation (MMR) impacted grades 7 (n = 61) and 8 (n = 141) students' learning and multimodal use on end-of-unit assessments. Half of each teacher's (n = 3) students received an intervention consisting of explicit instruction on MMR in science…

Science teaching deals with abstract concepts and processes that very often cannot be seen or touched. The development of Java, Flash, and other web-based applications allow teachers and educators to present complex animations that attractively illustrate scientific phenomena. Our study evaluated the integration of web-based animated movies into…

This study (1) explores the effectiveness of the contextualized history of science on student learning of nature of science (NOS) and genetics content knowledge (GCK), especially interrelationships among various genetics concepts, in high school biology classrooms; (2) provides an exemplar for teachers on how to utilize history of science in…

The Randomized Control Trials (RCT) design and its quasi-experimental kissing cousin, the Comparison Group Trials (CGT), are golden to some and not even silver to others. At the center of the affection, at the vortex of the discomfort, are beliefs about what it takes to establish causality. These designs are considered primarily when the purpose…
