A method is suggested to incorporate instruction in the concept and the application of power considerations into an applied statistics course. This is based on designing one table usable for a wide range of the type of statistical tests usually introduced in such a course. (Author)

Describes a study that was designed to explore the effects of two teaching presentations (parsed and whole cartoons) and cognitive style (field dependent and field independent) on undergraduate students' ability to understand editorial cartoons. Use of the Group Embedded Figures Test (GEFT) is discussed, and hypotheses tested are explained. (32…

A teaching aid appropriate for a beginning course on experimental design is presented. The aid is a numerical example which illustrates some of the theoretical interrelations among three competing design analysis strategies for estimating treatment effects in random assignment designs. The analysis strategies considered are analysis of variance…

The two objectives of this study were to compare the results of the teaching of written composition to high school students, using a problem-solving approach, with the results obtained using a traditional approach, and to determine if a problem-solving approach produces a significant difference in reflective thinking skills. Three null hypotheses…

This study investigated relationships among locus of control, instructional mode, and achievement for externally and internally oriented students taught by the same instructor using two different teaching methods. A definite relationship was found among the variables, and internally oriented students attained higher achievement levels where…

Describes research with Dutch secondary school students that studied the effects of the presentation of more general (superordinate) concepts on the attainment of basic concepts, and the effects of two different forms of example presentation on concept learning. Computer based instruction and interactive video used in the study are described. (18…

This project was conducted in order to determine the practicality of using specialized videodisc instruction to help preservice elementary school teachers learn the Language Experience Approach (LEA) to teaching reading more effectively. Texas Tech University students enrolled in an interactive video course planned and produced the interactive…

Comparative research was conducted using gifted and average upper elementary and junior high school students to determine the effectiveness of utilizing microcomputers for the development of computer literacy and the implementation of curriculum courseware. Eighty students were selected as the treatment group and received instruction in the…

Describes a study of four methods used to instruct college students on searching PsycLIT on CD-ROM: (1) lecture/demonstration; (2) lecture/demonstration using a liquid crystal display (LCD) panel; (3) video; and (4) a computer-based tutorial. Performance data are analyzed, and factors to consider when developing a CD-ROM bibliographic instruction…
