This study compared students' learning in troubleshooting and problem solving activities. The troubleshooting activities provided students with solutions to conceptual problems in the form of refutation texts; namely, solutions that portray common misconceptions, refute them, and then present the accepted scientific ideas. They required students…

I examined the impact of a self-diagnosis activity on students' conceptual understanding and achievements in physics. This activity requires students to self-diagnose their solutions to problems that they have solved on their own--namely, to identify and explain their errors--and self-score them--that is, assign scores to their solutions--aided by…

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…

The purpose of this study is to compare alternative teacher education programs in English as a foreign language (EFL), biology, and mathematics to traditional programs in the same subjects. To do this, we analyzed data on all of the students who studied in the aforementioned programs during 2009 and 2010 in the largest college of education in…

During 2009, three alternative teacher retraining programs in English as a Foreign Language, mathematics and biology were launched for the first time in one of Israel's largest teacher education colleges. The programs, which offered varied economic incentives to participants, were initiated by the state owing to shortages of teachers in these…

Chemistry students in Israel have two options for studying chemistry: basic or honors (advanced placement). For instruction in high school honors chemistry courses, we developed a module focusing on abstract topics in quantum mechanics: Chemistry--From the Nanoscale to Microelectronics. The module adopts a visual-conceptual approach, which…

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…

This is a comparative study of the image of the scientist held by Israeli Jewish and Arabic student teachers from various backgrounds. The image of female scientists among these groups was also investigated. Five groups of female students (N = 500) from four colleges were studied. Traditional tools (DAST) were combined with more informative…

The image of "the scientist" and its effect on the willingness to be a scientist and to follow a career in science were investigated in two different cultural populations of elementary and junior high school pupils in Israel: Hebrew-speaking (secular) pupils (N = 390) and Arabic-speaking Bedouin pupils (N = 185). Five different tools…

Dynamic inquiry learning emphasizes aspects of change, intellectual flexibility, and critical thinking. Dynamic inquiry learning is characterized by the following criteria: learning as a process, changes during the inquiry, procedural understanding, and affective points of view. This study compared the influence of open versus guided inquiry…

A new learning unit in chemistry, "Case-based Computerized Laboratories" (CCL) and Computerized Molecular Modeling" (CMM) was developed at the Technion. The CCL and CMM curriculum integrates computerized desktop experiments and molecular modeling with an emphasis on scientific inquiry and case studies. Our research aimed at…

This paper focuses on a learning strategy designed to overcome students' difficulty in understanding evolutionary change within the framework of geological time. Incorporated into the learning program "From Dinosaurs to Darwin: Evolution from the Perspective of Time," this strategy consists of four scaffolded investigations in which…

The case-based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual…

Attainment of laboratory course objectives was compared for tenth and twelfth grade Israeli students using two chemistry curricula: An Experimental Chemistry Program for Secondary Schools (ECPSS) and the CHEM Study program. ECPSS students more often than non-ECPSS students, and ECPSS girls more often than boys felt they had achieved the…
