BACKGROUND The Claim Evaluation Tools database contains multiple-choice items for measuring people's ability to apply the key concepts they need to know to be able to assess treatment claims. We assessed items from the database using Rasch analysis to develop an outcome measure to be used in two randomised trials in Uganda. Rasch analysis is a form of psychometric testing relying on Item Respon...

Identify the effect of an educational design according to repulsive (allosteric) learning model on achievement chemistry and lateral thinking. The sample consisted (59) students from third-grade intermediate students. They were randomly distributed into two groups (experimental control), equivalence was done in (chronological age, previous chemistry, intelligence, thinking). (30) experimental g...

When combining item types within assessments, it is important to consider the reliability of scores for each item type and the reliability of composite scores. This study investigated the effect of scoring procedures, section weights, and numbers of items per section on reliability, error variance, and conditional standard errors of measurement, using multivariate generalizability theory techni...

Interviews, Written tests  , and multiple choice tests are common methods used in employing people. Among these methods  , multiple choice tests is the easiest one because of th...

In this paper we report the results of an experiment designed to test the hypothesis that when faced with a question involving the inverse direction of a reversible mathematical process, students solve a multiple-choice version by verifying the answers presented to them by the direct method, not by undertaking the actual inverse calculation. Participants responded to an online test containing e...

Cognitive Diagnostic Assessment (CDA) is an alternative assessment which can give a clear picture of pupils’ learning process and cognitive structures to education stakeholders so that appropriate instructional strategies be designed tailored needs. Coincide with this function, the Ordered Multiple-Choice (OMC) items were incorporated into CDA developed in study. This paper describes developing...
