Presents a problem-solving activity in which students determine the effects on the water level in a pool when rocks are removed from a boat floating in the pool and placed into the water. Students discuss the problem, design an experiment to test solutions, conduct the experiment, and draw conclusions. (MDH)

Describes a contest where sixth-grade students observe the results of a week of planning, folding, testing, and comparing their best paper frog designs and hopping techniques. This integrated unit helps children unleash their imaginations and develop problem-solving skills. (PR)

Explores the potential for and limitations to learning science when middle-school students interact with computer simulations designed by scientists and built by professional programmers. Findings suggest that computer simulations can be used effectively when teachers use learning needs to guide choice of pedagogical style and alternate…

Examines technology education through technological problem solving in real-life contexts. Discusses theoretical framework and presents case studies from Ontario (Canada) elementary and secondary schools: writing and producing a play with grade 1 students, and community projects with grade 10 and 11 manufacturing technology students. Outlines…

Points out that college freshmen expect major changes in the academic environment as they move from secondary school. Recommends that faculty use this opportunity to show students how to think for themselves. (DDR)

Argues for liberating factors in education (student-centered practice, open-ended discussion, and art as a subject). Describes the "Visual Thinking Strategies" teaching method, which focuses on structured but open, group discussions about diverse art objects in order to help viewers develop a rapport with art, increase aesthetic…

Evaluates the effects of the scaffold explanation-based approach to collaborative discussion on students' understanding of photosynthesis. Forty-eight fourth- and fifth-grade students were divided into groups of high, average control (AC), and average intervention (AI). Students worked collaboratively and individually on two reasoning tasks.…

Describes a staff-development project that trains K-12 science teachers to use Interactive Multimedia Exercises (IMMEX) software, which expands teachers' content knowledge, teaching them about IMMEX and about how to create problem-solving exercises for diverse students. The paper examines project development and implementation, describes IMMEX…

Suggests that the instructional methods used with the subjects in the study by E. Fennema and others may have allowed teachers' gender stereotypes to be activated more than traditional instructional methods do, resulting in differences in primary-grade students' problem-solving strategies. (SLD)

Outlines major research findings in cognitive-discourse-processing research on learning from text. Describes general characteristics of classrooms based on constructivist principles of learning and that support critical thinking, problem solving, and collaborative learning. Argues that such classrooms raise a number of new issues for…

Indicates the importance of preparing prospective teachers who will be elementary science teachers with different methods. Presents the theoretical and practical rationale for developing a constructivist-based elementary science methods course. Discusses the impact student knowledge and understanding of science and student attitudes has on…

Basic theorizing regarding the notion of "cultural schemata" is presented as well as an analysis of how this theory impacts cross-cultural understanding in modern China. It is concluded that task-based problem-solving approaches, which have a sociocultural basis, can provide a very useful structure for developing oral language skills in…

Argues that the life sciences offer potential for practical work to be undertaken outside the classroom. Explores a rationale for such work and draws on reported studies from a number of countries. Contains 44 references. (DDR)

Used home observations and laboratory procedures with 85 Chilean mothers and infants to examine the association between infants' chronic undernutrition and maternal sensitivity, sociodemographic variables, and infants' play and problem solving. Found that maternal sensitivity was correlated with maternal education, maternal weight, marital…

Presents a conceptual framework for teaching science to students with disabilities. The framework suggests integration of explicit instruction in critical concepts, with cognitively-based approaches that emphasize problem-solving skills on real-world tasks. Implications for policy, professional development, and creation of learning environments…
