Summarizes concerns addressed in this special issue on Black students and mathematics, science, and technology education, including the following: (1) the imperative to improve the educational delivery system; (2) the consequences of failure to do so; (3) the necessity of empowerment; (4) the call for a multicultural approach; and (5) the role of…

Textbook-worksheet, traditional laboratory, and problem-solving treatments produced no significant differences in achievement by gender or treatment and no difference in perception by gender, but did produce a significant difference in perception by treatment in (n=268) students, grades 7-8.

Examines teachers' differing uses of student-gathered data during science investigations. The results show that student language use and concept understanding differed between two different instructional approaches. Suggestions are provided for using student-gathered data in teaching elementary school science. (LZ)

An overview is given of the consensus process for development of the frameworks underlying the National Assessment of Educational Progress (NAEP) assessments, with emphasis on those for the 1990 and 1992 mathematics assessments, the 1992 reading assessment, and the 1994 science assessments. Innovative techniques for 1992 are described. (SLD)

Focuses on the enhancement of chemistry students' skill in problem solving utilizing problem categorization techniques. Indicates that explicit training in categorization skills can lead to higher achievement in complex problem-solving situations but that such achievement may be limited by the lack of linkages between students' conceptual…

The cognitive factors that contribute to competence in the biological sciences were examined. The role played by cognitive style and analytical ability is discussed. The ability to abstract relevant information, evaluate it, and use it is affected by the skills of analysis and cognitive style. (KR)

Studies of the relationship between students' propositional knowledge (as measured by concept mapping tasks) and their study strategies (as measured by self-report questionnaires) for electricity in first-year university courses are described. The effect of propositional knowledge and prior knowledge on both conceptual knowledge and study…

This study investigated sex differences in chemical problem solving among Nigerian secondary school chemistry students (100 males and 100 females). Male students excelled over the female students in the following problem-solving processes: (1) problem understanding; (2) construction and execution of solution plans; (3) exhibition of structural…

Responds to the most commonly asked questions and criticisms regarding the Third International Mathematics and Science Study's assessment of students at the end of secondary school. Answers cover differences in age and grade levels, differences in enrollment rates, definitions of the U.S. advanced mathematics population, unbelievable numbers,…

Literature reviews and a study conducted in Malawi suggest that poor performance in science among students in developing African countries is caused by the absence of vocational incentives rather than by evidence of a conflict between traditional beliefs and science. Explains that science-performance improvement for students in developing…

Used hierarchical linear models to estimate the extent to which five inquiry-based teacher practices promoted student achievement and reduced achievement gaps among diverse students. Data from the National Education Longitudinal Study suggest that teacher practices that improve overall academic excellence simultaneously are as likely to contribute…

The goals of this chapter are threefold. The first goal is to examine the scientific attainment of African Americans in the post-"Brown" era. The term scientific attainment is used here to describe more broadly mathematics and scientific achievement as measured in trend studies, academic coursework, and degrees. A second, related goal is…

Primary science has rightly been recognised as one of the great successes in UK education over the last 20 years--a jewel in the National Curriculum crown. Its successes are evidenced by the high numbers of pupils achieving the target levels in national tests and by the rising number of science lessons rated as good or better in school inspections…

The purpose of this article is to describe an independent evaluation of the impact, in eighteen countries, of the Third International Mathematics and Science Study of 1999-Repeat, usually referred to as TIMSS-R. The countries of interest were all low- and middle-income countries that had received financial assistance from the World Bank, after a…

The shift from a centrally-controlled to a market-oriented economy in the early 1990s put pressure on the Romanian education system to reform both the curriculum and methods of instruction employed in primary and secondary education. At least part of the pressure to implement educational reforms came from the relatively poor performance of…
