The preliminary draft for a course in Strength of Materials and Materials Testing Laboratory contains a day by day teachers guide and an outline for laboratory activities. The guide includes sequence of topics, suggested reading assignments, demonstrations, and worksheets. The outline provides material for the development of a laboratory manual…

This manual is the teacher's guide for the two mini-units "Observing" and "The Nature of Models," part of a series of units designed for non-academic high school students by the 1970 Senior High School Science Workshop Committee. Each unit consists of five lessons presented in the format: objectives, materials, references, teaching suggestions,…

Problems in assessing the validity and reliability of the Mid-Continent Regional Educational Laboratory (McREL) tests of the inquiry skills of biology students are discussed by reference to the first trial version of the first Explorations in Biology (EIB) booklets. Since students learn during the two parts of the test, coefficients of stability…

In this seventh paper of the Research Review Series, commissioned by the Science and Mathematics Education Information Analysis Center in cooperation with the National Association for Research in Science Teaching, 189 studies in the ERIC SE collection which are concerned with secondary school science, published in 1968 or 1969, are cited and…

A simple model proposing that grading practices in a high school science course are related to the percentage of eligible students enrolled in that course and in the next course in the science sequence was tested using data from 27 California suburban schools. Ease of grading was considered as the discrepancy between students' mean concurrent…

The project consisted of making a multi-level teaching film titled "Rocks and Minerals of the Ouachita Mountains," which runs for 25 minutes and is in color. The film was designed to be interesting to earth science students from junior high to college, and consists of dialogue combined with motion pictures of charts, sequential diagrams, outcrops,…

The booklet is part of a series which tests some skills biologists use in their investigations. A series of diagrams of a biological community over a period of 10 years indicates an increasing bird mortality, and students are asked to choose a puzzling event that they would want to investigate if they were biologists. A scrambled programed text…

This booklet is part of a series that tests some skills biologists use in their investigations. Students are presented with several possible experiments to investigate one of the explanations for the changes in bird populations illustrated in Booklet A (SE 011 334). A separate series of data interpretation questions is presented for each…

This booklet is part of a series which tests some skills which biologists use in their investigations. It contains a series of questions related to possible experiments testing one of the possibilities offered in Booklet A (SE 011 336) to account for the "unusual event" shown in a series of pictures of a bird interacting with members of its own…

The booklet is part of a series which tests some skills biologists use in their investigations. A series of drawings of the inhabitants of two fictional villages, and a number of extracts of literature concerning congenital malformations, introduce the first question in this test, which asks students to identify an unusual event shown in the…

This booklet is part of a series which tests some skills used by biologists in their investigations. Students are asked a series of questions about one possible explanation of the "puzzling event" concerning human deformities presented in Booklet A (SE 011 338) and directed to a set of questions on data interpretation. The particular questions…

This booklet is part of a series which tests some skills biologists use in their investigations. A series of photographs of 3 rats in a Skinner box in which they had learned to obtain water by a bar-press response, but from which they receive rat pups, is used to present a puzzling event which students are asked to identify. Students indicate the…

This booklet is part of a series which tests some skills biologists use in their investigations. Questions are asked about investigations of the maternal behavior of rats, which is related to the "puzzling events" presented in a series of photographs of rats in Skinner boxes in Booklet A (SE 011 340). In a series of questions, depending upon the…

This list of currently available films and filmstrips pertinent to instrumentation has been compiled from information solicited from many government and private sources. The 1969 compilation has been organized into the following eight categories: (1) principles of measurement and basic measurements; (2) analysis instrumentation; (3) automation and…

This study examines the relationship between two measures of inquiry-verbal communication: The Science Classroom Activities Checklist (SCAC) and a modified form of the Parakh System of Interaction Analysis. The sample for this study consisted of ten randomly selected classrooms: three ninth-grade general science classrooms, six ninth-grade earth…
