This journal highlights five papers by international authors on various topics in education. In the first article, it was hypothesized deductively that extroverts will show more fluctuations in attending than introverts and that individuals with high neuroticism show more fluctuations in attention span than less neurotic persons. The second article presents a quality control system for developing reliable and valid, teacher made, objective-referenced tests. The third article attempts to illustrate the usefulness of the Weighted Net Percentage Difference (WNPD) technique as a methodological tool for the analysis of theoretical social mobility models. The fourth article, written in French with a summary in English, describes the analysis of the regulatory effect of three kinds of feedback (stereotype, specific, and feedback with self-control) on preoperational subjects. The final article in the compilation describes a pilot educational experiment concerning the teaching of English as a second language in Belgium. A chronicle of summaries of research in progress and a section with abstracts of reports presented to the seventh World Congress of the International Association for the Advancement of Educational Research are also included.
