This study aimed to examine the representations of nature of science (NOS) in the eight histories of science selected from three series of integrated science textbooks used in junior high school in China. Ten aspects of NOS were adopted in the analytical framework. It was found that NOS had not been well treated in the selected histories of…

This study examines graphing calculator technology availability, characteristics of teachers who use it, teacher attitudes, and how use reflects changes to algebra curriculum and instructional practices. Algebra I and Algebra II teachers in 75 high school and junior high/middle schools in a diverse region of a northwestern state were surveyed.…

Examines the line graphing ability of middle/high school students (N=625) to provide baseline data on the mastery of line graphing subskills. Results show that seventh- and eighth-grade students were less successful in graphing than high school students, suggesting that graphing skills should be introduced and emphasized in earlier grades. (JN)

Examined elementary and junior high school students in grades 2, 5, and 7 to determine baseline data about student performance on mental computation. Reports performance levels, difficulties of different types of mental computation, and preferences for doing computations mentally, with calculators, or by hand for each grade level. (MDH)

Uses the Theory of Planned Behavior to examine factors that predict junior high and secondary students' (n=303) attitudes toward participating in district science fair competitions, beliefs about who would approve or disapprove of participation, and perceptions of control. Results indicate that science fair entry appears to be involuntary and that…

Describes LOGO programming activities accomplished by seventh grade students in France, including those involving graphics, geometry, and movement commands. Includes descriptions of various LOGO commands (statements) used by students as well as program listings. (JN)

Examines an eighth grade science class that integrated mathematics and science through the use of technology. Reports that integrating mathematics and science classes positively affected students' achievement in math. (Contains 20 references.) (Author/ASK)

Investigates relationships between question level, response level, and lapse time for a total of 238 questions asked by student teachers on the junior high and senior high levels. Classroom interactions were taped and questions dichotomized into memory (knowledge) and above memory (comprehension, application, analysis, synthesis, evaluation)…

An individualized mathematics program for eighth graders is described. The program includes the use of diagnostic testing, individual learning prescriptions, commercially-prepared materials, weekly progress checks, and three instructors. (MN)

An inservice course was developed to a large extent in a Logo-oriented environment. Evaluation results show that teachers were successful in creating Logo programs and that the course fostered positive views about computers and growth in certain mathematical concepts. However, ongoing support from curriculum coordinators and/or administrators is…

Evaluated are 28 classroom variables from 33 eighth-grade science classes to identify variables useful in predicting achievement. (SL)

Compares student performance on fraction/number line tasks which varied length and equivalence. Associating proper fractions was easier on number lines of length one rather than length two; and where number of equivalent line segments in each unit segment was the same as the denominator, rather than twice that number. (CS)

Presents a position intended to stimulate prompt and vigorous action to promote interest in junior high school science teacher preparation programs based on several cited factors which have seemingly contributed to lack of concern for such. Data from a survey of junior high school science teachers is summarized and comparisons made. (EB)

An activity is presented which involves making a stadia tube from a cardboard mailing tube and using it to measure horizontal and vertical distances using the properties of similar triangles. (MN)

Presents an extension of Pick's theorem for simple closed polygonal regions to unions of simple closed polygonal regions. Students are guided to discover Pick's theorem from sets of data including numbers of boundary points and numbers of interior points. (Author/MKR)
