Presents samples of educational material adapted for laboratory use on the subject of the pH scale, dilution skills, and their relevance to biology. The experiments were developed for use in both ninth-grade heterogeneous and tracked classes in biology. Students were assessed for academic achievement in relation to their operational reasoning…

The purposes of this paper are (1) to demonstrate that medical microbiology laboratory exercises should be presented with a focus on medical applications, not just traditional microbiology and (2) that exercises devoted to differential diagnostic decision making can be used to enhance the problem solving of students.

The goals of this curriculum, developed as a summer course for the Young Scholars Program at The Ohio State University-Columbus, are as follows: (1) enable students to develop an understanding of the concept of a system; (2) help students gain an appreciation of the value of systems; (3) develop skills in working with systems; (4) expand skills in…

This manual was developed to guide drafting instructors and vocational supervisors in sequencing laboratory instruction and controlling the flow of work for a 2-year machine trades training program. The first part of the guide provides information on program management (program description, safety concerns, academic issues, implementation…

A survey of 102 New Jersey secondary school science teachers, department chairpersons, and supervisors concerning their laboratory accident-rate was conducted during the 1981-82 school year. Results indicate that accidents occur on a weekly basis even among a sample of experienced teachers who were interested in safety. The number of accidents…

This manual, part of a one-semester course for North American agriculture specialists preparing to work in Latin America, is built around specimens of agricultural writing in Spanish.

The Prime Minister's Committee on Natural Science in Education in Great Britain reported in 1918 that "...in many schools more time is spent in laboratory work than the results obtained can justify." Seventy years later this conclusion can often still be drawn. This is particularly a problem in open distance education where laboratory practicals,…

This paper describes the characterization of a student's framework of heat and temperature, and the development of a microcomputer-based laboratories (MBL) intervention program for grade 9 and grade ll students. The report presents the results of classroom study, including interview questions and answers and pretest/posttest, from experimental and…

Estuarine Oceanography is one in a series of single-topic problem modules intended for use in undergraduate and earth science courses. Designed for those interested in coastal oceanography or limnology, the module is structured as a laboratory supplement for undergraduate college classes but should be useful at all levels. The module has two…

Research was undertaken to investigate various methods of presentation of a computer based science simulation as it related to student content knowledge of the simulation concepts. Three treatment groups of sixth grade students were used in the study: (1) two students per computer interacting with the simulation; (2) a total class presentation of…

This is the student's text of one of the eight units of the Intermediate Science Curriculum Study (ISCS) for level III students (grade 9). The chapters include basic information about heredity, activities, and optional "excursions." A section on introductory notes to the student explains how to use the book. Data tables and empty spaces…
