A problem solving strategy, Thinking Aloud Pair Problem Solving (TAPPS), developed by Arthur Whimbey to help students monitor and understand their own thought process is presented. The TAPPS strategy encouraged the students interact verbally with each other to solve chemistry problems and improve the achievements in chemistry.

Based on an account of how two classes of primary five students in Singapore engage in the learning of English, Mathematics and Science by playing the role of global citizens, the paper suggests an alternative but realistic approach to teaching global citizenship education. Set against the back story of Atlantis facing ecological, social and…

The Martin Luther King School in Boston and nine other Massachusetts public schools used a grant from the Massachusetts Department of Education to expand their school days by at least two hours. Each school lengthened the time students spent in reading and math instruction. Farbman focuses on the Martin Luther King School's foray into an extended…

This paper reviews recent literature in order to identify factors affecting student performance in introductory high school and college physics courses. An important factor identified was formation of cognitive structures such as formation of problem solving schemata. It was concluded that Piagetian concepts such as concrete and abstract reasoning…

This book contains hands-on science laboratory activities for grades 4 through 9 that use discrepant events to challenge students. All of the "puzzlers" are based upon science principles and include directions for building gadgets that explain the "puzzlers." Topics covered include: volume conservation, magnetic phenomena,…

Subcellular processes like meiosis are frequently problematic for learners because they are complex and, except for the extent that they can be observed under a light microscope, occur outside of our direct experience. More detailed characterization of what underlies various degrees of student understanding of a process is required to more fully…

The purpose of this investigation was to identify and describe the differences in the methods used by experts (university chemistry professors) and nonscience major introductory chemistry students, enrolled in a course at the university level, to solve paired algorithmic and conceptual problems. Of the 180 students involved, the problem-solving…

Physics learning studies demonstrate that students' pre-instructional world knowledge is often logically antagonistic to the principles of Newtonian mechanics taught in introductory physics courses. Under these conditions psychological theory predicts that learning will be inhibited, a prediction consistent with both the experiences of physics…

This document reorts on an educational research study involving 75 eighth-grade students to determine the effects of problem solving instruction on the ability of students to apply proportional reasoning in problem situations. Results suggest that changes in basic reasoning skills such as proportional reasoning are long term, highly dependent on…

A prescriptive model of problem-solving performance is described. The aim of the model is to specify explicitly how problems should be described initially in such a form as to facilitate their subsequent solution. According to the model, the process of initial problem description can be decomposed into two successive stages. The first uses general…

A brief overview of CHEMEX--a problem-solving, tutorial style computer-assisted instructional course--is provided and sample problems are offered. In CHEMEX, students receive problems in advance and attempt to solve them before moving through the computer program, which assists them in overcoming difficulties and serves as a review mechanism.…

Describes a study which sought to identify development patterns related to the acquisition of proportional reasoning in two areas, namely electricity and chemical solutions. Results from children ages 9-11 indicated that development of understanding of chemical solutions was asymmetric whereas it was symmetrical with electricity. Includes sample…

Contends that school science programs should return to the visionary programs of the 1960's, which developed logical thinking and problem solving. These have since given way to a barren emphasis on fact acquisition and "cookbook" lab activities. (TE)

Argues that science programs developed during the 1960's should be replaced by "science/technology/society" (S/T/S) programs, which build on students' curiosity and concern about local problems. (TE)

Describes three types of chemical content, learning strategies for each type, and methods of teaching students to use the appropriate strategies. Provides suggestions for improving students' ability to learn. (CW)
