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 examined the reflection interview as a tool for assessing and facilitating the use of "systems language" amongst 11th grade students who have recently completed their first year of high school biology. Eighty-three students composed two concept maps in the 10th grade--one at the beginning of the school year and one at its end.…

There is growing interest in the impact of Jewish and Arab historical narratives on intergroup relations and conflict. A randomized placement comparative study set out to examine it empirically. Conventional-Authoritative official narrative, Empathetic Dual narrative, and Critical-Disciplinary multiple-source teaching interventions were designed…

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…

Traditionally, children's books are in a printed format and shared book reading is done with an adult. In recent years, interactive E-books have become a common medium for children's books and shared book reading is diminishing. This study compared the contribution of book format to the development of literacy in kindergarten children. We…

Instruction in higher education has developed significantly over the past two decades, influenced by two trends: promotion of active learning methods and integration of web technology in e-Learning. Many studies found that active teaching improves students' success, involvement and thinking skills. Nevertheless, internationally, most instructors…

Children with mental retardation have pronounced difficulties in using cognitive strategies and comprehending abstract concepts--among them, the concept of sequential time (Van-Handel, Swaab, De-Vries, & Jongmans, 2007). The perception of sequential time is generally tested by using scenarios presenting a continuum of actions. The goal of this…

The purpose of this study was to determine how children at different ages understand the concept of temperature, examining particularly the logicomathematical aspects of the concept. In doing so, three developmental approaches were compared: (1) Piaget's structuralist approach; (2) Siegler's rule assessment approach; and (3) Anderson and…

The difficulties that younger students experience in understanding concepts related to the use of variables in computer programming are examined through descriptions of two studies: (1) detailed case studies of six highly intelligent children--three fourth graders and three sixth graders--who learned to program in BASIC during 60 hours of…

School students' conceptual frameworks in astronomy and students' levels of knowledge and conceptualization were examined for 130 students in grades 2 through 12. Knowledge and conceptualization increased with school age. A test administered to 892 students in 7 schools demonstrated that schools contributed little to education in astronomy. (SLD)

The relationship between language, thought, and concept formation has been a central issue in many studies and theoretical discussions in various domains--philosophy, psychology, anthropology, and linguistics. The relation between language and concept development can be framed as two opposing questions: (1) Does the child learn concepts first and…

The use and analysis of student generated propositions linking two scientific concepts (photosynthesis and respiration) were examined before and after the study of photosynthesis. A proposition-generating task (PGT) was used as a diagnostic tool to indicate student misconceptions and partial understandings. Focus was on determining: how the nature…
