The paper argues that contemporary test validity theory places the consequences of testing on the lives of all college applicants at the back of the test validation argument. It introduces the notion of test efficacy as a process to gather evidence on claims on consequences of testing on all college applicants that can be traced back to validity.…

Constructing mathematical proofs is a fundamental yet challenging skill in secondary school geometry. While technology has been used to scaffold different aspects of the proving process, existing approaches often separate inquiry and conjecturing from formal proof or focus on structural and technical assistance without addressing students' initial…

In this article, we interrogate the concept of methodological 'failures' as they arise during fieldwork, in the process of collecting empirical data. We highlight how the techniques of validity horizon matrices and power analysis can be used as methodological tools to illustrate moments in the fieldwork process where these 'failures' occur and to…

Looking for closed forms for an integral depending on one parameter, we obtain integral identities and new integral presentations of Catalan numbers. Wallis formula appears as an important tool.

The study dealt with a research environment in which the treatment effect is heterogeneous, and in which individuals use their assessments of the treatment effect to decide whether or not to enroll in an intervention program. In this article, a new methodology is proposed for examining the validity of the specified research environment in a given…

Professor Elana Shohamy was born in New York and moved to Israel at a young age. It was an interesting time for the country and the Hebrew language. In this article, Professor Shohamy shares her keen insights into her experiences growing up in Israel. She obtained her teacher's certificate from David Yelin Teacher's College in Jerusalem,…

Course of study, target student population, structure of matriculation examination, student outcomes and attitudes of student toward various components of this examination are described. It was found that this examination not only offers a fair, educationally valid assessment but also provides support and direction which result in more effective…

A mathematician's work consists of proving theorems, calculating, and making mathematics understandable. An assistant for all three components is a Computer Algebra System. We describe and discuss various CAS-assisted processes for proving theorems, and discuss the constraints which can appear regarding efficiency, confidence in the result and…

The process of constructing and validating a questionnaire for use in course evaluation in a teacher education program in Israel is described. (MSE)

A broad description is given of admissions procedures to Israeli universities. In Israel, a single unified test, the Psychometric Entrance Test, is used for admission to the various universities. Issues of validity and reliability and problems of ensuring fairness for non-Hebrew speakers are considered. (SLD)
