The aim of this study was to investigate the effectiveness of instruction supplemented by conceptual change texts (CCTs) over traditional instruction on students' understanding of electrochemical (galvanic and electrolytic) cell concepts. The participants of the study consisted of 64 students from the two classes of a high school located in…

Cooperative learning has been proven to be helpful in enhancing the learning performance of students. The goal of a cooperative learning group is to maximize all members' learning, which is accomplished via promoting each other's success, through assisting, sharing, mentoring, explaining, and encouragement. To achieve the goal of cooperative…

The purposes of this study were to: (1) examine whether or not the construction of concept maps by students improves their achievement and ability to solve higher order questions in chemistry, (2) investigate the differential effect of the treatment by gender and achievement level, and (3) explore the relationships between performance on concept…

Education programs have fostered advanced levels of graphic representation ability in young children but have not detailed the specific mechanisms responsible for the accelerated growth. Research suggests that between 6 and 8 years of age children begin to observe more carefully before drawing and that observation prompts aid children's…

This article contains a description of the organization and method of use of an active learning environment named MODeLeR, (Multimedia Object Design Learning Resource), a tool designed to facilitate the learning of concepts pertaining to object modeling with the Unified Modeling Language (UML). MODeLeR was created to provide an authentic,…

The purpose of this study was to determine the effect of computer aided instruction and traditional method of instruction on the junior secondary school students achievement in mathematics. Four research questions and hypotheses were stated and tested in the study. The design of the study was the pre-test post-test control group experimental…

The aim of this study was to determine whether explicit instruction in phonemic awareness and phonemically based decoding skills would be an effective intervention strategy for children with early reading difficulties in a whole language instructional environment. Twenty-four 6- and 7-year-old struggling readers were randomly assigned to an…

This paper reported on investigation in which a simulation, experimental class of student learning was compared with a control class where the simulation is not used. (Editor/RK)

Author severely criticized a book on encounter groups by Lieberman, Yalom, and Miles (1973) and stated that it was a methodological morass, theroetically obsolescent, and almost totally unjustified in its conclusions. (Author/RK)

An approach to the analysis of an aptitude-treatment-interaction (ATI) design in which the treatment groups are based on an underlying factorial structure is described and illustrated. The approach emphasizes description with point and interval estimation. The example design considered consisted of two nominal treatment variables and one interval…

Research was conducted on pilot stress during simulated emergency flight conditions. Catecholamine (adrenaline and non-adrenaline) secretion for twenty United States Air Force student pilots and thirteen instructor pilots was determined during daily activities, during simulated flights performed in high realism simulators, and during actual…

The experiment studied the "relative effectiveness of tangible and social rewards upon the performance of a simple discrimination learning task by culturally disadvantaged children." Also assessed were the effects of the sex of the subjects (Ss) and the examiner. Ss were 144 five- and six-year old youngsters in a Georgia Head Start…

The purpose of this study was to determine the efficacy of induced affect as a pregroup training experience for coping with stress related to participation in an encounter group. Twenty-six subjects who volunteered to participate in an encounter group randomly were assigned to three treatment groups: Induced Affect Training plus the Encounter…

Experimental hypotheses are proposed which assert (1) that "thought" and "language" are distinct but both are part of linguistic performance; (2) that "thought" is central, and "language" is a symbolic system that one uses to refer in various ways to what he thinks; and (3) that immediate memory works with utterances and linguistic texts over a…

Research concerned with the compensatory education of disadvantaged children points to language deprivation as a primary causative factor in the "cumulative deficit" in education and school failure of these children. From a psycholinguistic framework, a method was devised to teach some of the essential linguistic skills in a short intensive…
