Discusses the importance of fostering critical thinking in chemistry. Presents strategies to improve critical thinking that were used in general chemistry for science and engineering majors, a similar course for less-prepared science and engineering majors, and a course for nonscience students. (JRH)

Describes how discrepant events in science can be used to stimulate and motivate the use of thinking skills in learning scientific concepts. (ZWH)

Three activities in which students identify and demonstrate similarities and differences in plants and in plant growth are presented. The activities include background information, objectives for the tree ring activities, a list of needed materials, procedures, evaluation procedures, and a glossary. (KR)

Reports on specific problem-solving difficulties of 240 chemistry teachers from 5 Nigerian states who volunteered to take part in 3 written tests and an interview. Describes the contrasts between successful and unsuccessful problem solvers, and discusses the pedagogical and psychological implications of the findings. (16 references) (JJK)

Discusses the use of drawings to nurture problem-solving attitudes and independent learning. Drawings help develop thinking skills, clarify misconceptions, develop representational preferences, supply a context for relationships in K-8 mathematics, and illustrate mathematical connections. (MDH)

Previous research has cast doubt on children's ability to use specified evidence when making causal inferences, or, indeed, to differentiate between the specified evidence and their own preconceptions, or "prior theories." The present study continues previous work by distinguishing between children's reasoning in conditions where…

Examined is the situation in which pupils invent mathematics on their own and teachers' reactions to this situation. The assimilation of students' original ideas into correct mathematical concepts is discussed. (CW)

Discussed is the idea that models should be taught by emphasizing limitations rather than focusing on their generality. Two examples of gas behavior models are included--the kinetic and static models. (KR)

Discussed is the use of writing as a tool to monitor student growth and development. The value of writing to help overcome obstacles such as misconceptions and preconceptions is stressed. A concept map of a hierarchy of writing strategies is provided. Stressed is the value of writing in the development of process skills. (CW)

Presents contributions by six mathematics teachers responding to the question: "How has the history of mathematics mattered to me in my mathematics teaching?" Answers touch the topics of how and why, how benefits are accrued, use of original texts, integration into core curriculum courses, and pitfalls of history. (MDH)

Emphasizes, and illustrates with examples, the importance of taking classroom time to rectify incorrect student thinking by immediately undoing, or unraveling, students' misconceptions, errors, or misapplications. When this process is cultivated without a judgmental attitude on the part of the teacher, students' confidence is inspired and…

Presents results of intensive clinical interviews with 11 high school chemistry students representing a broad range of achievement levels as selected from 180 students who completed a written test upon completion of an instructional unit on chemical change. Results indicate that students commonly experience difficulties in chemical knowledge,…

Focuses on the conceptual change processes of 17 fourth-grade students as they grapple with the abstract concept of human rights. Discusses limitations and successes in students' learning within the framework of conceptual change and motivation research. (CFR)

Presents 13 examples in which the intuitive approach to solve the problem is often misleading. Presents analysis of these problems for five different sources of misleading intuitive generators: lack of analysis, unbalanced perception, improper analogy, improper generalization, and misuse of symmetry. (MDH)

This monograph describes the origins of the learning cycle, related research, and how future research might be conducted to further the understanding of theories of instruction. A wide range of information is synthesized, producing a coherent framework for better understanding the theory of the learning cycle. The monograph identifies various…
