The purpose of this study was to examine the predictive effects of inquiry-based and teacher-directed instructional practices on students' attitudes toward science and science achievement in a nationally representative sample of 7,708 15-year-old-students from Taiwan who took part in the sixth cycle of the Program for International Student…

Students' science knowledge and skills are considered critical to growing the intellectual capital on which societies rely to innovate and prosper. However, recent research has documented notable declines in students' intrinsic valuing of science and science achievement in Australia and other western countries. As a result, there have been calls…

Inquiry-Based Teaching Practice (IBTP) is an essential component of science education, and promoting its implementation is at the heart of various reform efforts. Even though science teachers regard IBTP as an essential pedagogical method, they rarely use it for various reasons. This study utilizes Bronfenbrenner's ecological framework to examine…

Previous research has demonstrated the potential of examining log-file data from computer-based assessments to understand student interactions with complex inquiry tasks. Rather than solely providing information about what has been achieved or the accuracy of student responses ("product data"), students' log files offer additional…

A science achievement model was separately investigated for students in low and high achieving schools (LAS and HAS) in Turkey. Then, gender differences based on variables that significantly contributed to each achievement model were investigated. The student-level variables that were under investigation for multiple regression analyses include…

The purpose of this study was to investigate the effects of the Common Knowledge Construction Model (CKCM) lesson sequence, an intervention based both in conceptual change theory and in Phenomenography, a subset of conceptual change theory. A mixed approach was used to investigate whether this model had a significant effect on 7th grade students'…

The PISA assessment instruments for students' scientific literacy in 2000, 2003, and 2006 have each consisted of units made up of a real world context involving Science and Technology, about which students are asked a number of cognitive and affective questions. This article discusses a number of issues from this use of S&T contexts in PISA…

Much research has focused on student views about physics concepts, with an emphasis on the identification of alternative conceptions, and how curricula and professional development may ameliorate the situation. However, there has been little work on determining the extent of, and in separating, the student and teacher/classroom level variables…

Science education standards established by American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) urge less emphasis on memorizing scientific facts and more emphasis on students investigating the everyday world and developing deep understanding from their inquiries. These approaches to instruction…

In this investigation we employed a case study approach with qualitative and quantitative data sources to examine and discover the characteristics of the processes used by a midwestern U.S. school system to adopt and implement a new K-6 science curriculum. Analysis of data yielded several results. Elementary teachers received what they requested,…

This article reports on the results of a planning grant studying the effects of a highly rated curriculum unit on a diverse student population. The treatment was introduced to 1500 eighth grade students in five middle schools selected for their ethnic, linguistic, and socioeconomic diversity. Students were given pre-, post-, and delayed posttests…
