This student fieldbook provides exercises for a three-week course in limnology. Exercises emphasize applications of knowledge in chemistry, physics, and biology to understand the natural operation of freshwater systems. Fourteen field exercises include: (1) testing for water quality; (2) determination of water temperature, turbidity, dissolved…

This document contains student progress checks designed for use with individualized modules 23 through 25 in the military-developed course on basic electricity and electronics. The course is one of a number of military-developed curriculum packages selected for adaptation to vocational instructional and curriculum development in a civilian…

This bulletin briefly describes research activities in the field of curriculum development for comprehensive and upper secondary schools in Finland. The comprehensive schools, established by law in 1963, offer a uniform curriculum to all Finnish students for the first nine years of school. After attending the comprehensive school, students may…

Described is an introductory materials science laboratory program which emphasizes crystal structure both on the atomistic and microscopic scale and the dependence of materials properties on structure. The content of this program is classified into four major areas: (1) materials science, (2) mechanical behavior of materials, (3) materials testing…

This guide contains lesson plans and outlines of science activities which present concepts of solar energy in the context of chemistry and physics experiments. Each unit presents an introduction to the unit; objectives; required skills and knowledge; materials; method; questions; recommendations for further work; and a teacher information sheet.…

EDUCATIONAL TECHNOLOGY IS OF GREAT IMPORTANCE NOW BECAUSE THE ENORMOUS INCREASE IN THE RATE OF TECHNOLOGICAL CHANGE WHICH TOOK PLACE DURING THE 1940'S HAS ALTERED OUR SOCIETY FROM A PERFORMANCE TO A LEARNING SOCIETY. IN A PERFORMANCE SOCIETY, LEARNING IS A PRELUDE TO THE PRACTICE OF A FIXED SET OF SKILLS. HOWEVER, IN A LEARNING SOCIETY THE…

THE INCREASED USE OF PROGRAMED MATERIALS CREATE A NEED TO ESTABLISH PROCEDURES FOR DETERMINING THE READING DIFFICULTY OF THE MATERIALS BEFORE EXTENSIVE FIELD TESTING BEGINS. AN EXPERIMENT WAS CARRIED OUT WITH 189 FOURTH GRADE, 271 FIFTH GRADE, AND 140 SIXTH GRADE STUDENTS. THE POPULATION OF MATERIALS FOR THIS STUDY CONSISTED OF NINE FOURTH GRADE…

A 15-minute interview was conducted separately with 2 5th grade boys (1 Caucasian, 1 Negro) who were matched on IQ and 4 pupil characteristics; home background, personality, social behavior, and academic ability. A semantic differential scale was constructed for the 4 characteristics, and 5 disability labels were assigned to each child:…

A study was conducted to determine whether a significant relationship exists between the teacher's judgment of her pupils' social status and the pupils'"actual social rank" in the class. Six teachers (one for each grade from one through six) in a selected northern Indiana elementary school were given forms listing their pupils' names accompanied…

This project consisted of the design, trial use, and evaluation of instructional procedures designed to reduce the amount of routine information given directly to the students by the instructor in chemistry laboratory courses for college freshmen. Printed materials gave the student a decision-making role in planning his laboratory work. Tape-slide…

Compared were written, oral, and construction responses to science demonstrations of economically advantaged and disadvantaged sixth grade students. The study was designed to gain a greater understanding of academic performance of disadvantaged pupils in elementary school science. Five demonstrations were presented to each pupil, who then wrote…

A study investigated the relationship of traits measured by the California F Scale (a measure of anti-democratic attitudes) with changes in attitudes as measured by the Minnesota Teacher Attitude Inventory (MTAI) during a one-semester course of educational psychology. A 2 x 2 factorial design was used, classifying 132 sophomore education students…

Described is an experimental, quantitative model developed by the New York State Education Department to evaluate state-level financing strategies for higher education. It can be used to address a variety of questions and takes into account a host of direct and indirect relationships. It uses computer software and optimization algorithms developed…

A simple deterministic macroeconomic computer model was tested in a junior-senior level economic statistics course to demonstrate how and why some common errors arise when statistical estimation techniques are applied to economic relationships in empirical problematic situations. The computer model was treated as the true universe or real-world…

A series of five video-cassettes showing children from ages three to eight years was developed for use in an undergraduate developmental psychology course. Each cassette was viewed on an optional basis, with extra credit toward student's final grade awarded for viewing. Study guides accompanied each cassette. An evaluation of the effectiveness of…
