This study examines the existing knowledge that pre-service elementary teachers (PSETs) have regarding heat energy, heat transfer and insulation. The PSETs' knowledge of heat energy was initially assessed by using an activity: determining which container would be best to keep hot water warm for the longest period of time. Results showed that PSETs…

The present study was carried out with 46 teacher candidates taking the course of "Thermodynamics" in the Department of Physics Teaching. The purpose of the study was to determine the difficulties that teacher candidates experienced in explaining the heat, work and internal energy relationships in the processes of adiabatic compression…

The aim of this study is to reveal the students' and pre-service teachers' understanding of light, sight and related concepts at different educational levels, from primary to higher education. A cross-sectional approach was used since the participants were of different age and educational level. The sample of this study consisted of 30 eighth…

A common challenge for many primary pre-service teacher educators is to rekindle interest in science content with future teachers who often express a lifetime of negative associations with school science. This pilot study investigated if the notion of wonder could be utilized with preservice teachers as a vehicle to develop more positive…

The purpose of this study was to compare the effectiveness of the conceptual change oriented instruction through cooperative learning (CCICL) and traditional science instruction (TI) on 4th grade students' understanding of earth and sky concepts and their attitudes toward earth and sky concepts. In this study, 56 fourth grade students from the…

The current study, undertaken in the Sultanate of Oman, explored twelfth grade students' common misconceptions in seven chemistry conceptual areas. The sample included 786 twelfth grade students in Oman while the instrument was a two-tier test called Chemistry Misconceptions Diagnostic Test (CMDT), consisting of 25 items with 12 items…

Students' understanding of energy has been primarily within the domain of physics. This study sought to examine students' understanding of concepts relating to energy and the human body using pencil and paper questionnaires administered to 610 students in Years 8-12. From students' responses to the questionnaires, conceptual patterns were…

The study investigated the mental models of primary school children related to the day/night cycle. Semi-structure interviews were conducted with 40 fourth-grade and 40 sixth-grade children. Qualitative and quantitative analysis of the data indicated that the majority of the children were classified as having geocentric models. The results also…

The study investigated tenth-, eleventh-, and twelfth-grade students' alternative ideas relating to the motion of a body travelling in the field of gravity with an initial horizontal velocity. The sample of the study consisted of 40 tenth-grade students, and 33 and 40 eleventh-grade students that attended different sections of upper secondary…

Students' conceptual understanding of Newton's third law has been the subject of numerous studies. These studies have often pointed out the importance of addressing the concept of interaction in teaching Newtonian mechanics. In this study, teachers were interviewed in order to examine how they understand interaction and use it in their…

Presents the findings of a qualitative study carried out in a poor and problematic area of Brazil to investigate whether constructivist teaching practices are evident in the daily lessons in state elementary schools. Some teachers were found to employ genuinely constructivist methods. Analyzes the theoretical background, methodology, and…

Explores the current images that students have of scientists, student perceptions of science study in school, and student awareness of their use of science outside of school. Fifth grade students (N=117) were the subjects of this study that asked students to sketch scientists and school science. (DDR)

Identifies certain conceptions regarding the science content studied by students aged 9-11 years and develops a strategy for altering these conceptions. Reviews research on misconceptions and defines action research. (DDR)

Informs teachers about using concept maps as a learning tool and alternative assessment tools in education. Presents research results of how students might use concept maps to communicate their cognitive structure. (Author/KHR)

Examines situations in which science impinges on everyday life and in which school science education is of little use. Argues that relevancy goes beyond acquiring knowledge of conceptual understanding. Contains 33 references. (DDR)
