This study examined how students' position on social-scientific issues (SSIs) influenced their performance on attitude toward science, science conceptual and argumentation learning. It defined two positions adopted by students regarding SSIs: affirmative and oppositional. The interactions between student position and two learning environments --…

The purpose of this study is to examine the effects of different ways to use visualizations on high school students' electrochemistry conceptual understanding and motivation towards chemistry learning. Expanding upon a model-based learning approach (Khan, 2007), we adopted a VGEM sequence (View, Generate, Evaluate, and Modify) to create three…

In this study, we have synthesized the research on visualization and representation to propose a model consisting of 4 major components of visualization competence in learning science: constructing, interpreting, transforming, and critiquing visualizations. We have developed and validated an assessment that measures students' visualization…

So far relatively little research in education has explored the pedagogical and learning potentials of applications (Apps) on tablet PCs (TPCs). Drawing upon research on learning technologies and taking an embodied perspective, this study first identified educational functionalities of TPCs and generated guidelines to design educational Apps for…

This study explores the relationship between students' clicking behaviors, discussion processes, learning outcomes, and a prominent feature of clicker systems--the whole class' response results aggregated by clickers in real time. The results indicate that, while teaching Newton's laws of motion, displaying the real-time responses of the whole…

The purpose of this study was to report the results of a nationwide survey of Taiwanese high schools students' understandings about electric circuits. The study involved two stratified random samples consisting of 7,145 students in Grades 8 and 9, and 2,857 students in Grade 11, accounting for about 2.3% of the total enrolment in the corresponding…

The National Science Concept Learning Study represented one of the largest and the most extensive surveys of its kind undertaken in Taiwan in recent years. A total of 36,093 students from the sixth, eighth, ninth, and eleventh grades participated in the main study. This paper provides the background information about the sampling and booklet…
