The literature of educational psychology and the literature used by writers in educational psychology

Using Psychological Abstracts as the source of the original sample (“first-level”), various characteristics of the literature of educational psychology are compared with the characteristics of a “second-level” literature (defined as the literature that the first level cites). In particular, the scatter (dispersion) of periodical articles over periodical titles is looked at for both levels. The journals most cited within the literature of educational psychology are identified.     

University class size: Is smaller better?

This study investigates the relationship between class size and achievement at the college level. Recent meta-analyses have found a strong relationship between class size and student achievement, but few of the studies examined class size larger than 40 or university-age populations. This analysis examines a university's testing-center data-archives representing 305 sections from 24 different courses. Section sizes ranged from 13 to 1,006. A total of 16,230 test scores were analyzed. The results of this investigation reveal that at the college level, class size may be less important an influence on student achievement than some educators have thought.     

Flavor- vs. tone-cued shock avoidance

In a direct comparison, flavor-cued rats learned to avoid shock in a two-way shuttlebox as well as, or better than, tone-cued rats. These results stand in contrast to the prevalent view that rats encounter difficulty in forming flavor-shock, but not tone-shock, associations. In attempting to account for this contrast, we note that experiments revealing cue-modality specificity employ an aversion paradigm and record ingestive behavior. It is argued that both the paradigm and the dependent variable are inappropriate for assessing shock-avoidance learning, and that cue-modality specificity in such a setting reflects paradigm and response choice rather than a general characteristic of rats.     

Evaluating the quality of peer and self evaluations as measures of student contributions to group projects

ABSTRACT

Educators in higher education commonly use peer and self evaluations to help assess student performance on group projects. Although these evaluations provide multiple benefits, many educators are wary of using them due to concerns about their quality. This study addresses three questions debated in the literature regarding the quality of these assessments. How much do students differentiate among peer contributions through their ratings? How reliable are peer ratings? How much agreement exists between peer and self ratings? Although these questions have been addressed to varying degrees in past work, their answers have been far from settled. While many studies focus on just one of the questions, this study’s data make it possible to address all three questions for the same group of students as well as examine each question by student performance level. The evaluations assessed in this study were completed by a large number of students under conditions associated with obtaining more valid and reliable ratings. Overall, the results provide support for using peer and self evaluations to help assess student contributions to group projects. Peer ratings were largely reliable as group members generally agreed on the scores given to their peers. In addition, most students differentiated among group member contributions through their ratings. Students also tended to rate themselves higher than their peers rated them. This study has implications for how peer and self evaluations can be most effectively used by educators to measure student performance in group work.     

The attainment of doctoral degrees at Flemish Universities: a survival analysis

This paper examines the propensity to attain a Ph.D. degree at the five largest universities in Flanders, the Dutch speaking part of Belgium. It provides insight into the rate at which junior scholars appointed at the universities involved attained their Ph.D.-degree, and the duration of the doctoral training period. Cox’s regression model was applied to statistically analyse the influence of a number of ‘demographic’ and ‘merit’ variables, and variables related to funding source and type of appointment of the junior scholarly staff. Large differences in Ph.D. durations and attainment rates were found across funding sources, research disciplines and types of appointments. The policy background and implications are discussed briefly.     

The Effect of Group Orientated Classroom Management Procedures on Individual Pupils

Summary This study was designed to test the hypothesis that group orientated classroom management procedures may achieve their apparent success merely by raising still further the on‐task behaviour of non‐troublesome pupils. To this end, 1812‐13 year old pupils in a secondary school remedial class were observed and their individual levels of on‐task behaviour recorded. The class teacher's use of approval and disapproval was also noted.

Following the collection of baseline data, a modified, simple ‘rules, praise and ignoring’ intervention strategy was implemented, followed by a partial reversal to baseline conditions. Mean class on‐task behaviour was clearly shown to increase from 77% at baseline to 91% during intervention and this was maintained during the partial reversal. Moreover, it was shown that every pupil's on‐task behaviour increased, these increases varying between 3 and 33%, the pupils with the lowest baseline levels making the biggest gains.     

Overcoming resistance to formal instructional development processes

The instructional development (id) process sometimes is perceived as being too time-intensive and as delaying instructional materials development. Course writers holding these perceptions may resist following a formalid process or give only cursory attention to early stages in the process. Such a situation can create conflict between course writers and instructional designers responsible for implementing a particularid model. This article describes a way instructional designers can overcome some of the resistance to following theid process.     

Latent Class Modeling with A Time-To-Event Distal Outcome: A Comparison of One,Two and Three-Step Approaches

Latent class methods can be used to identify unobserved subgroups which differ in their observed data. Researchers are often interested in outcomes for the identified subgroups and in some disciplines time-to-event outcome measures are common, e.g., overall survival in oncology. In this study Monte Carlo simulation is used to evaluate the empirical properties of latent class effect estimates on a time-to-event distal outcome using one, two and three-step approaches. Both standard and inclusive bias-corrected three-step approaches are considered. One-step latent class effect estimates are shown to be superior to the evaluated alternatives. Both the two-step approach and a standard three-step approach, where subjects are partially assigned to latent classes, produced unbiased estimates with nominal confidence interval coverage when latent classes were well separated, but not otherwise.
