The current study focused on scaffolding programmes, including cognitive and meta-cognitive components, for science problem solving in a computerised learning environment to identify their unique effects on aspects of student motivation. Using expectancy-value theory as a conceptual framework, the current study focused on two motivational aspects:…

The present research is part of a longitude research study regarding the questioning behavior of students in the inquiry chemistry laboratory in Israel. We found that students who were involved in learning chemistry by the inquiry method ask more and higher-level questions. However, throughout the years, we have observed that differences between…

This study involved 458 ninth-grade students from two different Arab middle schools in Israel. Half of the students learned science using project-based learning strategies and the other half learned using traditional methods (non-project-based). The classes were heterogeneous regarding their achievements in the sciences. The adapted questionnaire…

In this study we explored whether the use of teachers' demonstrations significantly improves students' understanding of redox reactions compared with control group counterparts who were not exposed to the demonstrations. The sample consisted of 131 Israeli 8th graders in middle schools (junior high school). Students' attitudes and achievements as…

Twenty-eight freshmen majoring in biology and/or chemistry in an Arab college in Israel, were given a pre-test and a post-test in which they had to identify the control group and design a controlled experiment. During the course an intervention was used. Science was taught by inquiry while using strategies that promote higher-order thinking skills…

While interest is central to learning, considerable disparities have been reported between students' science interests and the science curriculum. This study explores how 5th grade students' (n = 72) competence, relatedness and interest levels changed as a consequence of using two online learning environments, which bridged the students' anonymous…

Describes the use of concept mapping (CM) in design, instruction, and assessment related to microbiology lessons prepared for high school students in Israel. Indicates that students utilizing CM displayed an overall, higher achievement gain than students in traditional classes. Recognizes that some teachers did not thoroughly exploit the potential…
