With even the simplest bivariate regression, least-squares solutions are inappropriate unless one assumes a priori that reciprocal effects are absent, or at least implausible. While this discussion is limited to bivariate regression, the issues apply equally to multivariate regression, including stepwise regression. (Author/CTM)

Reviews research studies on note-taking and identifies possible questions for future research in that area. A case is made for the inclusion of such studies within the domain of educational technology research. A 49 item bibliography is attached. (MER)

The authors' thesis is that educational research responds to external social and policy events rather than creates them. They attempt to forecast external developments in Scotland which will affect research and highlight the trend toward collaborative research. (SJL)

Thirty-three research articles based on t-tests, F-tests, or Pearson product-moment correlations selected from the "Journal of Medical Education" were examined for adequate research reporting. Nearly one-half did not report sufficient data or were found to have low power values. Guidelines for research reporting are discussed.…

Using grade point average and graduation-nongraduation as two separate criteria and eight predictor variables selected from doctoral applicants' folders at an Arizona university, a canonical correlation of .624 for a sample of 65 graduate students shrank to -.095 for a cross validation sample of 21 students. (CTM)

Design, analysis, and reporting considerations for the application of analysis of covariance (ANCOVA) techniques in educational settings are described. Numerous examples are drawn from the national follow through evaluation, and suggestions for improving reports using ANCOVA-type techniques are presented. (Author/BW)

Factors involved in pre-planned and post-planned evaluation of program effectiveness are compared: (1) reliability and cost of data; (2) internal and external validity; (3) obtrusiveness and threat; (4) goal displacement and program direction. A model to help program administrators decide which approach is more appropriate is presented. (Author/MH)

Strasser and Deniston's own analysis (TM 504 254) shows that post-planned evaluations are unsuitable substitutes for pre-planned evaluations. When viewed as post-experimental interviews, however, post-planned evaluations can produce valuable information which complements traditional experimental and quasi-experimental evaluations. (MH)

This study attempts to evaluate Mexico's television-based secondary education system, Telesecundaria, by comparing the mathematics and language achievement of Telesecundaria students with that of students receiving traditional instruction. Student background and ability, community, teacher, and classroom variables are considered.…

A simplex process model of the cross-lagged correlation paradigm was applied to 16 tests administered to samples of Black and White males and females in grades 5, 7, 9, and 11. Relationships among the measures as well as the use of the model are discussed. (Author/JKS)

It is shown that using formulae for the estimation of sampling errors based on simple random sampling, when a design actually involves cluster sampling, can lead to serious underestimation of error. Jackknife and balanced repeated replication are recommended as techniques for dealing with this problem. (Author/CTM)

Examines the feasibility of using a time-series design intensively in a school situation. Investigates student attitudes toward a biology class using the operant single-subject design. Despite the developmental nature of this study, it demonstrates that the five-item semantic differential is a valid and easily used instrument. (Author/MA)

A survey of existing research designs and accompanying techniques if presented along with brief assessments of their usefulness for programs of different types. The authors stress particularly the use of field experiments for the assessment of prospective social policies and programs. (Author/MV)

In view of changes in teacher education programs and the "oversupply" of teachers in the nation, it seems important to work with high school students to determine their interests and to select "promising" students who would enter Northern Illinois University in the Teacher Education Program. Considers the Future Teachers of…

Examines teachers' perceptions of pupil ability and determines whether their perceptions are distorted in any systematic way by the order or sequence of information they receive about the pupil. (Author/RK)
