Internet learning opportunities via the National Science Foundation-supported New Jersey Networking Infrastructure in Education project are described. Their data-centered approach to science and math skills instruction is illustrated by two examples from each of the three styles of activities: (1) collaboration; (2) using public domain databases;…

Describes the statistical test of chi-square analysis. Explains how this test can be used in biology instruction. Examples from blood typing are used. (PR)

Vocabulary fixed-item (FIT), computerized-adaptive (CAT), and self-adapted (SAT) tests were compared with 121 college students. CAT was more precise and efficient than SAT, which was more precise and efficient than FIT. SAT also yielded higher ability estimates for individuals with lower verbal self-concepts. (SLD)

Factor-Q is a problem-solving computer assisted instruction system for teaching polynomials in grades 9-12 that addresses the limitations of most problem-solving programs, among others, the user interface. The system is designed to help students master the skills of factorizing polynomials. It demonstrates the ease with which inadequately trained…

The benefits of pre-first programs and grade retentions are not consistently supported in the research literature. Study investigates the short- and long-term effects of pre-first programs on students' (n=66) academic achievement in reading and mathematics. No significant differences were found in six of the eight analyses conducted, indicating…

Maximum likelihood and Bayesian procedures are presented for item selection and scoring of multidimensional adaptive tests. A demonstration with simulated response data illustrates that multidimensional adaptive testing can provide equal or higher reliabilities with fewer items than are required in one-dimensional adaptive testing. (SLD)

A six-year case study was conducted on the impact of, and teachers' role in, the use of computers and the Mathcad program in mathematics instruction at a technical college. Results for 2 teachers and 51 of their students showed definite stages in the teachers' use of the computer technology. (SLD)

The relationship between instruction that challenged students academically in a supportive social environment and achievement gains in mathematics and reading was studied for students in 53 third-grade classrooms served by Title I funds. Findings indicate that higher-order learning and material connected to out-of-school experience were seldom…

Measures of mathematics achievement were administered to 1,043 Belize students at the beginning and end of third grade. Student learning of advanced mathematics concepts during the year was related to teacher knowledge of mathematics and mathematical ability but not to teacher pedagogical training. Student learning of basic concepts was not…

Reviews the use of interactive multimedia in teacher education. Explores design, development, and evaluation issues for four examples of multimedia learning environments in mathematics and science: the Student Learning Environment, Investigations in Teaching Geometry, Reflecting on Elementary Science, and the Project Support Environment.…

The Wisconsin Emerging Scholars Program (WESP) is a nonremedial, multicultural workshop approach to learning calculus that emphasizes community and collaboration. This approach is designed to foster substantial participation of underrepresented ethnic minority students and alleviate the problems of isolation and lack of support in a large,…

Research on the fairness, effectiveness, and efficiency of selecting students is reported in the context of selecting educationally disadvantaged black students in South Africa for a one-year mathematics- and science-based student-centered compensatory university preparatory program. A formula comprised of weighted mathematics, science, and…

Explores how students take what they understand through reading and talking about literature and express their ideas in art, drama, music, or math. Argues that one way learners push their understandings and create more complex meanings is through such transmediation. Offers examples of responding to literature through multiple sign systems. (SR)

A study of national longitudinal data examined effects of rural Catholic high schools on mathematics achievement, high school graduation rates, and the likelihood that high school graduates attend college. Findings indicate that rural Catholic high schools had a positive effect on mathematics test scores and no effect on graduation rates or rates…

Developed profiles of computer-using elementary and middle school mathematics teachers and had experts rank them as though the teachers were receiving a hypothetical award. Experts reported weights of the dimensions they used in making judgments. Actual award judgments were highly predictable from profile dimensions. What experts considered most…
