This study attempts to determine whether there exists a negative interconnection between the creative and testable nature-of-science (NOS) conceptions in college students' conceptual ecology by investigating, through a pair of IHV-assisted teaching experiments, the effect of raising the status of each NOS conception in students' conceptual ecology…

The accuracy with which regression models estimate treatment effects is dependent upon a number of conditions. The stability of the regression line (a function of sample size and correlation between pretest and posttest) is said to be the most important of these conditions. The utility of regression models is proportional to the size of the…

Two types of sensitivity indices were developed in this paper, one internal to the total test and the second external. To evaluate the success of these statistics the three criteria suggested for a satisfactory index of item quality were considered. The Internal Sensitivity Index appears to meet these demands. Certainly it is easily computed. In…

Describes an investigation of time as a learner variable in an individualized mode of health instruction where time was permitted to vary, hypothesizing that aptitude as measured by a standardized test could correlate more closely with time in instruction than with achievement where students were expected to reach criterion levels. (MBR)

Objectives of this study were to create a prototype of an interactive hypermedia textbook and to explore the relationships between learners' performance and use of available learning tools (i.e., textbook glossary and navigation map). The effects of prior knowledge on textbook use and performance were also investigated. (11 references) (EA)

Discussion of hypertext structures focuses on three studies of preservice teachers that assessed the effects of different methods of explicitly mapping expert knowledge structures onto hypertext on the acquisition of structural knowledge. Topics addressed include time on task, semantic networking, cognitive limitations of browsing behavior, and…

Describes a study of undergraduates that examined the effects of behavioral versus cognitive review strategies on learning outcomes and depth of processing during computer-based instruction. Near and far transfer learning are discussed, the use of locus of control is explained, and posttest differences are examined. (eight references) (LRW)

A study investigated the effect of research-based instructional strategies on the reading achievement of students in grades two through five. Instructional process variables were assembled into a manual used to train 24 experimental teachers. The five categories of variables were (1) classroom environment, (2) lesson introduction, (3) lesson…

The development of a modified semantic differential measure of school-related attitudes of grades 3-6 children is described and its validation involving 99 children is reported. Each of the four scales of this measure, Attitude Toward-School, -Language Arts, -Teachers, and -Arithmetic, was found to be unidimensional. Internal consistency estimates…

Responding to the Texas Education Agency's (TEA) "Essential Computing Competencies for Educators" (1983), the teacher's education program at Texas A&M University developed several computer literacy courses for its students. An evaluation was conducted of the first of these courses, "Microcomputer Literacy for Educators," to…

A study was made of the effects of programed instruction versus the use of course objectives and reference materials on learning, transfer, and attitudes in two adult experimental groups. The subject was mathematical concepts basic to introductory statistics. Mathematical tests and attitude scales were administered before and after the experiment.…

The relationship between physically and psychologically stressful experiences and the anxiety and self concept of 33 male and 11 female participants (aged 16-38 years) in a 23-day Colorado Outward Bound (OB) course was analyzed. It was hypothesized that the effects of the OB experience would: be the same for male and female participants; alter…

The ability of a dynamic measure of phonemic awareness to predict progress in beginning reading was studied with 38 kindergartners. Results support the utility of the developed measures and demonstrate the applicability of the principles of dynamic assessment to the measurement of phonemic awareness. (SLD)

Describes a study of state employees that was conducted to examine the strengths and weaknesses of the use of teleconferencing to increase creativity among workers. A model of creativity is explained, the pretest/posttest used to assess teleconferencing effectiveness is presented, and implications for teleconferencing are discussed. (eight…

The primary focus of this experiment was to determine the effects of verbal skill training for the Preliminary Scholastic Aptitude Test (PSAT) on secondary school students. The other concern was whether there was a correlation between class grades and PSAT scores. Finally, there was a determination as to whether there were any attitude changes…
