This curriculum guide, developed to establish statewide curriculum standards for the Louisiana Competency-based Education Program, contains the minimum competencies and process skills that should be included in a chemistry course. It consists of: (1) a rationale for an effective science program; (2) a list and description of four major goals of…

This curriculum guide, developed to establish statewide curriculum standards for the Louisiana Competency-based Education Program, contains the minimum competencies and process skills that should be included in a biology course. It consists of: (1) a rationale for an effective science program; (2) a list and description of four major goals of…

Designed to address the major conceptual problems associated with light and vision, appearances of surfaces, and color, this module can be used with high school students or college nonscience majors including those in elementary education. It is one in a series developed by the project "Overcoming Critical Barriers to Learning in Nonmajors'…

According to the ACT theory of skill acquisition, cognitive skills are encoded by a set of productions, which are organized according to a hierarchical goal structure. People solve problems in new domains by applying weak problem-solving procedures to declarative knowledge they have about this domain. From these initial problem solutions,…

This life science activity module was designed to facilitate student conceptualization of plant growth. It is intended for use primarily in elementary grades but may be useful at higher grades. It provides students with hands-on experience and observational skill development. The package provides: (1) a teacher background sheet; (2) an activity…

This publication provides information and activities for teaching about water, whether certain objects will sink or float, and process skills including observing, classifying, inferring, measuring, predicting, and collecting and interpreting data. There are 14 lessons in the unit. The first four lessons deal with the classification of objects and…

Describes a two-quarter chemistry course designed to enable civil engineers to perform water analysis studies. (PB)

THIS PROJECT COMPARED THE EFFECTIVENESS OF UNMODIFIED UNIVERSITY COURSES TAUGHT VIA CLOSED-CIRCUIT TELEVISION WITH THE EFFECTIVENESS OF THE SAME COURSES CONVENTIONALLY TAUGHT FOR ONE SEMESTER. THE ACCEPTIBILITY OF TELEVISED INSTRUCTION TO STUDENTS, FACULTY, AND ADMINISTRATORS WAS MEASURED, AS WAS THE FEASIBILITY OF USING MODERATE COST TELEVISION…

THREE EXPERIMENTS WERE CONDUCTED ON THE USE OF PROGRAMED INSTRUCTION TO TEACH GENERAL SCIENCE TO EIGHTH GRADE STUDENTS. THREE VISUAL STIMULUS MODES AND THREE AUDIO STIMULUS MODES WERE USED WITH EITHER LINEAR OR BRANCHING PROGRAMS AND SUBJECT CONTENT WHICH WAS EITHER NON-CONCRETE, CONCRETE, OR ACTION-PROCESS. LEARNER CHARACTERISTICS VARIED WERE IQ,…

CLOSED CIRCUIT TELEVISION WAS WELL RECEIVED BY DENTISTRY STUDENTS AT NEW YORK UNIVERSITY BUT FAILED TO YIELD SIGNIFICANT GAINS IN ACHIEVEMENT OVER CONVENTIONAL INSTRUCTION. TWENTY-ONE NULL HYPOTHESES WERE TESTED ON 154 MALE SOPHOMORE STUDENTS, WHO WERE DIVIDED INTO GWO GROUPS, HALF BEING INSTRUCTED TO A LARGE EXTENT VIA CCTV, TV CLASS, AND HALF…

To test the hypothesis that if given a curriculum designed to develop cognitive functioning and taught by strategies designed to develop cognitive skills, students would then master more sophisticated symbolic thought earlier and more systematically than could be expected if this development had been left to the accidents of experience or if…

This study investigated (1) the extent to which thinking and problem-solving of fifth-grade students could be improved by the use of self-instructional programed lessons (the productive thinking program), (2) the relationship between productive thinking abilities and IQ-sex characteristics of the learner, and (3) the relationship between level of…

This bibliography, made up of approximately 350 entries concerned with many aspects of problem solving and concept formation in young children, has been designed for use by people primarily involved in experimental research in these areas of child development. Entries include experimental journal articles, conference papers, unpublished research…

This study on self-confrontation in teacher training presents the students' repeated assessments of subject-object relations both during the experiment and six weeks and two years after the experiment. For the experiment the student teachers were confronted with their own video-recorded micro-lessons; identification experiences and self-evaluation…

This report is one of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. Manuscripts and extended reports cover the following topics: iconic storage, voice-timing perception, oral anesthesia, laryngeal function, electromyography of speech production,…
