This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

The author proposes a design for science instruction in the middle school years, ages 9-13. (SJL)

Notes how laboratory experiences can help elementary school social studies pupils understand concepts such as cultural awareness, career education, advertising techniques, map and globe skills, music, transportation, and landforms. For each concept, information is presented on objectives, activities within a laboratory setting, and evaluation…

The philosophy, structure, and organization of a chemical engineering (ChE) process laboratory are discussed. The laboratory emphasizes the oral and communication skills of students who are part of groups that resemble an industrial process research and development group. An annotated list of students' experimental projects is included. (JN)

The advantages of using invertebrates in teaching physiological principles are discussed. The ability to illustrate with greater clarity physiological principles, the range and variety of physiological processes available for examination, and the unlimited possibilities for student research are topics of discussion. (KR)

An exercise that uses a common bacterium, E. coli, in great numbers, to detect a demonstrable change in the ability of some cells to become resistant to the common antibiotic streptomycin is presented. The procedure for preparing and pouring the gradient antibiotic plates is provided. The advantages of using the Basic Fuchsin in the agar are…

Describes a computer game used in an introductory experimental psychology class which simulates in a few months the activities of years of effort in a research laboratory. Ideas on developing new computer based simulation games are included. (Author/JJD)

Describes the laboratory procedure suitable for an introductory organic chemistry procedure. (CP)

A five-week introductory unit on electricity, structured in a historical perspective provided by the letters of Ben Franklin, is described. (CP)

A list of demonstrations of discrepant events which have been found to stimulate the curiosity of students in science at the secondary school level are presented. A brief description of the materials and procedures for 15 of these demonstrations is outlined, with short explanations of concepts and principles involved. (MP)

Describes a laboratory exercise to demonstrate enzyme activity using gelatin and meat tenderizer. The exercise is adaptable to any grade level. (MA)

This was an experiment to test the extended discretion laboratory approach versus a guided-inquiry approach for teaching biology in a university setting. Among three criterion variables (examination, reports, and quizzes), only the laboratory report scores showed differences between groups and group-by-instructor interaction. (Author/YP)

Explores a way of analyzing laboratory activities that can help middle and high school science teachers to match their instructional goals with one of three appropriate types of activities: confirmation, generalization, or resolution. Examples and guiding principles for each kind of activity are given. (Contains 23 references.) (MDH)

A procedure for purifying DNA using either bacteria or rat liver is presented. Directions for doing a qualitative DNA assay using diphenylamine and a quantitative DNA assay using spectroscopy are included. (KR)

Discusses a microcomputer program that was created to simulate the behavior of a computerized "animal" so that students could practice the shaping of behavior. Describes mathematical algorithms that allowed the "animal" to show gradual improvements in directional movements after appropriate shaping. Reports that students were…
