Classroom discussion of scientific articles can be an effective means of teaching scientific principles and methodology to both undergraduate and graduate science students. The availability of classic papers from the American Physiological Society Legacy Project has made it possible to access articles dating back to the early portions of the 20th…

Primary teacher preparation courses to need support students in developing not only science content knowledge, but also pedagogical knowledge appropriate to the effective translation and representation of subject matter for learners in classrooms. In the case of the generalist primary trainee, this constitutes a considerable challenge. This study…

A learning cycle consists of three phases: exploration; conceptual invention; and expansion of an idea. These phases parallel Piaget's functioning model of assimilation, disequilibrium and accomodation, and organization respectively. The learning cycle perceives students as actors rather than reactors to the environment. Inherent in that…

This work designs and implements a virtual digital signal processing laboratory, VDSPL. VDSPL consists of four parts: mobile agent execution environments, mobile agents, DSP development software, and DSP experimental platforms. The network capability of VDSPL is created by using mobile agent and wrapper techniques without modifying the source code…

This physical science activity module was designed to facilitate developing concepts related to sound. 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…

Many educators feel that elementary school science programs should concentrate on phenomena and concepts that are literally tangible. This document serves as the teaching manual which accompanies the Capsela modular system of manipulative and motorized models. The experiments in the manual are intended to provide a structured approach to using the…

This collection of articles, originally published in national and international journals, is fifth in a series devoted to trends in teaching chemistry. The volume is divided into nine sections, each with an introduction explaining why papers have been selected and outlining their particular interest. Section I provides a list of atomic masses,…

TO COMPARE MODES OF TRAINING TEACHERS IN THE LECTURING SKILL OF REDUNDANCY WITHOUT USING DIRECT SUPERVISORY-TEACHER CONFERENCES, 94 TEACHER INTERNS WERE RANDOMLY GROUPED FOR SIX EXPERIMENTAL TREATMENTS. A RECORDING OF THE INTERN'S CLASSROOM PERFORMANCE WAS FOLLOWED TWICE BY A TRAINING SESSION AND ANOTHER RECORDING. TREATMENTS WERE--VIEWING A MODEL…

THIS EXPERIMENT IN THE ETV PROJECT SHOWED THE SUPERIORITY OF PUPIL PRACTICE AS A TEACHING METHOD AND STUDIED THE EFFECTIVENESS OF THE UTILIZATION VOLUNTEER (A PEACE CORPS VOLUNTEER CONCERNED WITH IMPLEMENTING ETV IN THE SCHOOLS) IN DIFFERENT SITUATIONS. THREE TREATMENTS WERE ARRANGED--(1) ACTIVE PUPIL PRACTICE WHERE BROADCASTS WERE COMBINED WITH…

This report of an educational experiment compares the methods and evaluates the results of two instructional approaches to language learning. The "community learning" method, in which emotional factors are believed crucial in the development of the instructional method, and a traditional approach are compared as to their effectiveness in the areas…

Four school districts were identified and selected to participate in the incentive project. One school each in Duval County, Florida; San Antonio, Texas; Cincinnati, Ohio; and Oakland, California was selected as an implementation site for either the teacher model of the teacher/parent model. Contracts were drafted for each site for payment of…

This report, a supplement to a previous report, presents final evaluation material on the success of the USOE incentives project. Either a teacher model or a teacher/parent model was implemented at a school in each of four sites -- Duval County, Florida; San Antonio, Texas; Cincinnati, Ohio; and Oakland, California. The report describes final site…

This final report is an assessment of an experimental class designed to determine whether students, grades nine through twelve with diverse backgrounds, could do field research on community problems. The course description and outline of the course define goals and methods of meeting these goals. Samples of materials used are included in the text…

This report is distilled from Rand's findings in previously reported research and from new research. It is addressed to school board members, administrators, and other educational decisionmakers who may be contemplating a performance contracting program. The guide follows the life cycle of a project and identifies the three major phases as…

This study is designed to compare "traditional" and "immersion" methods of language instruction to determine whether the latter is a viable alternative in four-year, secondary-school language programs. Both methods are evaluated on the basis of student achievement in comprehension, speaking, reading, and writing skills in Spanish. The hypothesis…
