This study is concerned with different forms of assessment of pupils' skills in experimentation. The findings of three studies are reported. Study 1 investigates whether it is possible to develop reliable multiple-choice tests for the skills of forming hypotheses, designing experiments and analysing experimental data. Study 2 compares scores from…

Research Findings: Few rating scales measure social competence in very young Spanish or Catalan children. We aimed to analyze the psychometric characteristics of the California Preschool Social Competence Scale (CPSCS) when applied to a Spanish- and Catalan-speaking population. Children were rated by their respective teachers within 6 months…

A two-phase FORTRAN IV program called ITANA-III for an IBM 1130 computer is described that permits computation of psychometric characteristics of multiple-choice examinations including test statistics (phase I) and item statistics (phase II). Consisting of 280 statements, the program can handle up to 200 items with not more than 9 alternatives…

Identifies those error items on the Bender-Gestalt Test which tend to discriminate over age and identifies those items which do not discriminate beyond certain ages. (RB)

Criterion referenced test methodology is used in this study for determining the extent of overtraining and undertraining through the use of the minimally acceptable performance level (MAPL), as proposed by Nedelsky (1954). A MAPL was computed for each area on a 320-item, 12-area test. The raw area scores of the technicians were transformed to…

One of a series of reports on the International Project for the Evaluation of Educational Achievement (in Mathematics).

THIS STUDY WAS DESIGNED TO DETERMINE THE RELIABILITY, VALIDITY, AND SOCIAL FAVORABILITY RATINGS OF 941 ITEMS THAT WERE THOUGHT TO BE DESCRIPTIVE OF CHANGE IN CHILDREN'S BEHAVIOR. THIS POOL OF ITEMS COULD THEN BE USED FOR SCALES MEASURING THE OUTCOME OF COUNSELING AND PSYCHOTHERAPY WITH CHILDREN. THE VALIDATION AND CROSS-VALIDATION SAMPLES INCLUDED…

THE POSSIBILITY OF ADMINISTERING TESTS BY PROJECTED METHODS WAS EXPLORED, FOCUSING ON THE ASSIGNMENT OF VALUES TO SPECIFIC TEST VARIABLES IN ORDER TO MAKE THE RESULTS OF PROJECTED TESTS COMPARABLE TO THOSE OF A NORMAL (CLASSROOM TEACHER ADMINISTERED) TEST ENVIRONMENT. THE VARIABLES OF (1) INTRA-ITEM EXPOSURE INTERVAL, (2) INTER-ITEM EXPOSURE…

A method of estimating the parameters of the Rasch Model removing the effect of ramdom guessing is presented. The procedure is an application of the ARRG (Abilities Removing Random Guessing) model recently developed for two parameter latent trait models. Under the Rasch model ARRG provides for estimation of abilities, removing the effects of…

PAVLOV (Paired Associate Verbal Learning Organizational Vehicle) is a Fortran coded program designed to facilitate the analysis of learning data. The program analyzes four classes of information parameters, list order, data format, and data. Utilizing this input, the program performs an in-depth measurement of several dependent variables for each…

A random group of 49 items was drawn from nine commerically available reading comprehension tests. Each test was classified independently by two judges as either a measure of the ability to find answers to questions answered explicitly or in paraphrase in the passages, a measure of the ability to draw inferences or deductions, or a measure of some…
