Teachers constantly face the challenges of the most effective methods of instruction that could enhance academic achievement and match the diversity among students. This study therefore aimed at examining the effects of metacognitive strategies on classroom participation and student achievement in Senior Secondary School Science classrooms. One…

SOMA (States-Of-Matter Approach) is an introductory chemistry program for all students in the tenth or eleventh grade (age 16-17), which introduces chemistry through the separate study of the three states of matter. SOMA is basically a formalistic approach. In this paper, we discuss the use of PARSEL modules in providing a teaching approach to…

Investigates the effect of computer-assisted instruction (CAI) when used as a supplement to classroom instruction to improve secondary school students' understanding of orbital shapes. Results indicate that the CAI approach enhanced student learning and helped them figure out cues portrayed in diagrams of atomic orbitals. (Contains 22 references.)…

Describes science in the Venezuelan school system which reflects on the process of development followed to design and validate the Biology Study Programs (BSP) with the emphasis on the relevance of curricular changes proposed in biological science for secondary education. (Contains 19 references.) (ASK)

Discusses an approach to teaching the structure of atoms using a teaching technique referred to as a jigsaw classroom. Reports that the jigsaw classroom involves arranging students in various types of groups for cooperative learning. (Author/MM)

Describes the effectiveness of an intervention training and draws attention to the most important factors to be considered in developing inservice programs for the promotion of Science and Technological Literacy (STL) teaching skills. Concludes that teachers who acknowledged the need for teaching social skills in conjunction with science concepts…

Presents two components of a piece of experimental equipment, the optical training ground and the electrical panel, which can be used to construct and test different electrical circuits and study laws of electricity, experimental problem solving, and basic light phenomena. (YDS)

Introduces an event in which two school teams from Argentina and Vietnam joined those from each Australian state in a race of model cars powered by the sun that provides a challenging and exciting approach for students to apply their scientific and technological knowledge to design and build the most efficient vehicles possible to gain hands-on…

Provides brief information about a water course in a secondary high school in Finland that specializes in natural sciences. Students cooperated with classes from the United States. (ASK)

Many examples of social topics such as global warming can be integrated into any introductory science class easily. Presents suggestions for integrating science and social topics, particularly the issues of transportation and energy use. (ASK)

Outlines and analyzes developments and issues in public examinations in the Caribbean region at the secondary school level. Focuses on the contribution of the Caribbean Examinations Council (CXC). Discusses the CXC syllabi and examinations for biology, chemistry, and physics. (Contains 18 references.) (ASK)

Describes the author's experiences incorporating cooperative learning strategies into a chemistry course. Includes information on organizing student working groups, preparing for and implementing cooperative activities, and helping students evaluate the effectiveness of their groups. (WRM)

Finds that the time required to attempt all the test items of each question paper in a four-paper sample was inversely proportional to the percentage of students who attempted all the test items of that paper. Extrapolates results to give guidelines for determining the feasibility of newly-developed exam papers. (WRM)

Explores the views of Japanese students (N=2478) concerning the nature of science, technology, and society via a questionnaire. Discusses the results within the context of Japanese culture. (DDR)

Explains a taxonomy of basic skills of science practicals that is used in the assessment of secondary science students. Details the assessment scheme which involves the evaluation of students through laboratory practical examinations, observational assessment, and written records of academic sessions. (DDR)
