Innovation is difficult to define because a practice which is innovative on one campus may not be innovative elsewhere. Nevertheless, a possible definition might be "a practice which is worthy of emulation and has not yet been put into use by a significant number of colleges." Administrators should seek instructional innovation for several…

The study was designed to determine how standard science skill builder activities can be modified or adapted for use by orthopedically handicapped students. Nine secondary level science experiments were selected for initial review and from these, three were selected for adaptation--use of the microscope, use of graduated cylinders, and use of the…

This learning module is intended to illustrate the functioning and uses of bridge circuits. The discussion and laboratory procedures suggested in the module presume familiarity with basic concepts of electronics such as voltage, current, resistance, capacitance, inductance, phase, and knowledge of such skills as breadboarding circuits from…

THE PURPOSE OF THIS STUDY WAS TO INITIATE A PROGRAM FOR TEACHING MUSIC READING SKILLS, USING THE PIANO KEYBOARD IN COMBINATION WITH PROGRAMED LEARNING, AND TO COMPARE IT WITH CONVENTIONAL METHODS OF MUSIC INSTRUCTION. FOURTH, FIFTH, AND SIXTH GRADERS AT ONE CLEVELAND PUBLIC SCHOOL COMPRISED THE CONTROL GROUP RECEIVING CONVENTIONAL MUSIC READING…

THIS EXPERIMENT COMPARED MERITS OF FOUR COMBINATIONS OF AUDIO-ACTIVE, AND RECORD-PLAYBACK ARRANGEMENTS IN HIGH SCHOOL FRENCH LANGUAGE LABORATORIES FOR 120 SOPHOMORES MATCHED ON FIVE PREDICTIVE MEASURES. ACHIEVEMENT TEST SCORES, GRADES, AND RATINGS BY THREE INDEPENDENT JUDGES WERE STATISTICALLY ANALYZED. BEST PERFORMANCE WAS ACHIEVED BY THE…
