Experiments were devised to determine teacher effectiveness on the basis of ability to communicate, on the assumption that no relevant learning will occur if communication is faulty. A series of communication games involved an encoder (teacher) and decoder (student) to provide tentative answers to the questions: 1) Are there individual differences…

The effectiveness of four methods of speech instruction with third and fourth grade culturally deprived boys and girls was compared. The methods of instruction varied in regard to the manner in which they were developed and in sophistication from simple instructions on the operation of audiovisual equipment and materials to a commercially…

The basic problem of this study was to develop a method for increasing the efficiency of the instructional process at the introductory level. The experiment compared two methods for doing the outside of class assignments in support of a course in library science instruction. The plan called for the control groups to do the outside assignments in…

This speech discusses the planning for and the implementation of the O.E.O. performance contracting experiments. The author argues that it was not performance contracting, but the O.E.O. experiment which failed. The author blames this failure not so much on the poor evaluation design, but rather on the number of interface problems which arose…

CERTAIN SPECIFIC ASPECTS OF HYPOTHESIS TESTS USED FOR ANALYSIS OF RESULTS IN RANDOMIZED EXPERIMENTS WERE STUDIED--(1) THE DEVELOPMENT OF THE THEORETICAL FACTOR, THAT OF PROVIDING INFORMATION ON STATISTICAL TESTS FOR CERTAIN EXPERIMENTAL DESIGNS AND (2) THE DEVELOPMENT OF THE APPLIED ELEMENT, THAT OF SUPPLYING THE EXPERIMENTER WITH MACHINERY FOR…

This study involving ninth-grade algebra students investigated whether learning in environments identified in previous research as effective (i.e., exhibiting high levels of learner involvement) elicit significantly higher levels of relevant achievement than do ineffective learning environments.
