This paper reports a study designed to examine the types of behaviors students exhibit while conducting laboratory activities and assess the effectiveness of strategies students employ. The sample was 42 students enrolled in a physics lab section at a single university. Three types of data were collected: (1) observational data during the lab…

This study explores how an Inquiry-Based Demonstration Classroom (IBDC) professional development program affects the extended inquiry instruction of secondary science teachers and how teachers view their extended inquiry practice while involved in the IBDC professional development program. To assess the impact of the program on participants'…

Different effects of instructional strategies on recall and comprehension of terms frequently used in formal analysis of art were examined. The study looked at a synthesis of three theoretical positions: dual-coding theory, schema theory, and elaboration theory. Two-hundred and fifty sixth-grade students were randomly assigned to three groups:…

This paper reports the preliminary results of an experiment on the impact of computer assisted instruction (CAI) on disadvantaged students participating in the U.S. Department of Labor's Job Corps Program. In 1980-81, data were collected from participants in the Job Corps Comprehensive Computer Program at a large center in the Southwest. The…

Facts and activities related to weather and meteorology are presented in this unit. Separate sections cover the following topics: (1) the water cycle; (2) clouds; (3) the Beaufort Scale for rating the speed and force of wind; (4) the barometer; (5) weather prediction; (6) fall weather in Iowa (sleet, frost, and fog); (7) winter weather in Iowa…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This teaching guide, designed to be read in…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the third year of secondary school without the aid of qualified teachers and conventional laboratories. This ZIM-SCI study guide is a five-part unit…

The purpose of this teacher's resource guide is to help science teachers incorporate the topic of acidic precipitation into their curricula. A survey of recent junior high school science textbooks found a maximum of one paragraph devoted to the subject; in addition, none of these books had any related laboratory activities. It was on the basis of…

This paper is a discussion of how videocassette tape recording is used and the results of its use, in general chemistry pre-laboratory instruction at the University of Southern Mississippi. (Author)

Internet-based learning systems, or e-learning, are widely available in institutes, universities, and industrial companies, hosting regular or continuous education programs. The dream of teaching and learning from anywhere and at anytime becomes a reality due to the construction of e-learning infrastructure. Traditional teaching materials and…

This paper presents an application of integration to the field of hydraulics. An integral relation for the time required to drop the fluid contained in a cylindrical tank from one level to another using a hole in the tank wall is derived. Procedures for constructing the experimental equipment and procedures for determining the coefficient of…

This document contains two case studies of adult education programs in Cameroon. Both case studies begin with a "face sheet" on which is recorded basic information about the program and the case study itself. One case study is intended to evaluate the impact of the agricultural university center in the Dschang area from 1977-1987 and to…

This exploratory study examined how middle-level students preferred to work on science and science-related problems. Assessing students' instructional preferences may be as important as determining their abilities before decisions about optimal forms of education can be made. Students' preferences may indicate the types of instruction most likely…

Provided in this teaching package are materials that clearly and simply unveil the mysteries of water pollution. Materials, written on an approximate seventh-grade level, include: (1) a student reading unit; (2) water quality factors pamphlet; (3) experiments; and (4) teacher's guide to field testing a local waterway. The student reading unit is…
