Describes activities that can be added to any chemistry curriculum and can offer students an opportunity to gain and practice skills in research, written and verbal communication, and database creation and use while working as a part of a problem-solving team. (JRH)

Contends that, to become a better critical thinker, one must not only develop expert thinking skills, but also become an expert at choosing the best skills for the particular situation. Reports on a study of critical thinking and metacognition among 65 college students. (CFR)

Investigates issues of conceptual understanding in teaching and learning mathematics provided conceptually based instruction on place value and two-digit addition and subtraction without regrouping in four first grade classrooms. Conventional textbook-based instruction was provided in two first grade classrooms. Experimental-group students scored…

This study examined the effects of 3 instructional methods--computer education, creative problem solving, and traditional gifted curriculum--on development of problem-solving skills of gifted students aged 8 to 12. Posttest scores of the computer education unit were significantly higher than scores for the computer literacy and problem-solving…

Describes pedagogical content knowledge model. Uses interviews and observation to examine development of pedagogical content knowledge of two student teachers in a one-year elementary teacher education program. Concludes student-teacher success requires supervisors' understanding and support. (TES)

Utilizes LOGO to teach the concept of inequalities by programing the turtle to take random walks in the coordinate plane restricted to predetermined regions defined by inequalities. The students task is to discover the inequalities that define the illegal areas into which the turtle must not move. Provides examples and corresponding computer…

Describes two investigations suitable for grades seven and eight that explore the properties of the figure created when the midpoints of an equilateral triangle or square are joined. (MDH)

Presents 5 school and home activities for the K-2, 3-4, 5-6, and 7-8 levels appropriate for beginning the school year that incorporate problem solving, collecting and analyzing data, and exploring patterns. Topics include a shopping spree, seat assignment, map-interpretation skills, and probability. Includes reproducible worksheets. (MDH)

Describes a problem to challenge students as they come back from summer vacation. Working in small groups, students discover Pick's Theorem, the formula to calculate the area of a polygon constructed on a geoboard. A writing assignment evaluates the students' efforts. (MDH)

Describes "talk-through" model of peer teaching in which student pairs are asked to verbalize their thinking processes as they work through a mathematical problem. Lists five benefits of using this method. (MDH)

A case study is presented of a science class for 10 underachieving gifted intermediate grade students. The paper describes how a focus on overcoming underachievement might conflict with the need for active, hands-on science activities. Suggestions are offered for integrating the goals of raising self-concept while developing skills of inquiry and…

Discussed is the place and teaching of trigonometry in a NCTM Standards-based mathematics curriculum. Presented is how these standards can be implemented in a technology-rich environment that encourages reasoning, communication, problem solving, and confidence building. Examples focus on functions, graphical sense, modeling, and identities. (KR)

The results of an experiment in teaching engineering graphics using the traditional lecture-homework-laboratory technique are compared to a newer lecture homework proposal. Although the newer method reduces professor-student contact, it may prove to be as effective as the older method requiring laboratory instruction. (KR)

Described is a study that used LOGO to improve the proportional reasoning ability of students enrolled in mathematics classes for students poorly prepared for college-level mathematics. Included are the methodology, procedures for using logo, and a discussion of the results. (KR)

Suggests that a discussion-based approach focused on experiences of actual environmental issues, encountered problematically, should characterize environmental education activities. An ecology exercise dealing with organic pollution of a river provides a context for the educational principles and ecological concepts included the study. (24…
