This study investigated Ontario science and biology teachers' practices and attitudes toward animal dissection and dissection alternatives. The data was collected through a mixed methods approach involving online surveys (n = 153) and subsequent telephone interviews (n = 9) with secondary school science and biology teachers. The findings indicate…

This paper proposes a technique for using the digital computer in science instruction (grades 1-12) which may well obviate the constraints of unreasonable cost and demand for complex and extensive software. Computer Simulated Experiments require a short amount of time at the terminal during which the student collects realistic simulated data.…

Briefly describes hardware and software requirements for a computer based learning system. The methods used in various systems are reviewed briefly. (TS)

Presented are the following articles: A Role for Computers in Teaching Biology; The Laboratory in General Microbiology; Rectifying the Misnomer; The "Message" of Pioneer 10: Interpretation and Role Playing for Beginning Science Students; The Project Oriented Laboratory as an Effective Teaching Method for Nonscience Majors; Environmental…

Reports experiences during a two-year period in introducing the computer to the laboratory and students to the computer as a laboratory instrument. Describes a working philosophy, data acquisition system, and experiments. Summarizes the laboratory procedures of nine experiments, covering mechanics, heat, electromagnetism, and optics. (YP)

Introduces two hands-on experiences, related to rotational motion and moment of inertia. Discusses the experimental procedures and provides figure of apparatus. (YP)

The assumptions common to all capture-recapture models for estimating population size are reviewed. A simulation using either a playing board, counters, and dice or computers is described. Classroom implications of using the board game are discussed. (KR)

Gives a review of four software packages including "Science Toolkit: Module 3--Body Lab" for measuring heart rate, lung capacity, and response time; "Project Zoo: Adventures with Charts and Graphs" for developing process skills; "The Body Electric" for explaining electrical activity in the body; and "M-ss-ng…

Describes course on applications of computers to chemistry, computer-assisted instruction laboratory on measurement/error for high school chemistry, sample dispenser-computer grading system for quantitative analysis courses, and computer programs on nomenclature/preparations/reactions and least-squares refinement of pseudorotation parameters in a…

Examined are applications of computer spreadsheets from simple record/observation tables to custom built analysis systems. The advantages and disadvantages depending on the use of these software packages are discussed. Several examples are used to illustrate possible applications. (CW)

Explains uses of computer hardware when it's no longer needed to teach computer literacy. Describes a mini-lab pilot project which consists of several computers mounted on carts used similarly as audiovisual equipment. Lists advantages, disadvantages, and percentages of time used for instruction, interfacing, word processing, graphing, and…

Describes a "tracing the sun" worksheet combining models with computer programs and classroom discussion. Provides the worksheet including the nine steps of the activity and several discussion questions. (YP)

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…

Describes a problem-solving activity integrating a laboratory investigation with a database activity using Appleworks. Presents typical displays of the databases. The objective of the laboratory was to determine the identity of a pure substance by measuring physical properties and searching the database. (Author/YP)
