The field of geometrical optics features a broad knowledge base concerning conceptual learning difficulties and student conceptions. However, in contrast to other areas of physics, no widely used standard test instrument exists to assess middle school students' conceptual knowledge of geometrical optics. This is even more true for other areas of…

What follows is a practical guide for establishing the validity of a survey for research purposes. The motivation for providing this guide is our observation that researchers, not necessarily being survey researchers per se, but wanting to use a survey method, lack a concise resource on validity. There is far more to know about surveys and survey…

Problem solving is a complex process valuable in everyday life and crucial for learning in the STEM fields. To support the development of problem-solving skills it is important for researchers and curriculum developers to have practical tools that can measure the difference between novice and expert problem-solving performance in authentic…

The primary measure used to determine relative effectiveness of in-class activities has been student performance on pre/posttests. However, in today's active-learning classrooms, learning is a social activity, requiring students to interact and learn from their peers. To develop effective active-learning exercises that engage students, it is…

The original SOCO Scale was reduced to 10 items by Thomas, Soutar, and Ryan (2001). The author conducted a pretest and a posttest in his Personal Selling class during the Fall 2009 semester. Significant differences by gender, student sales experience and family member in the sales field were identified. The author once again pretested the…

The aims of the study were (a) to develop a scale to measure university students' task value and (b) to use confirmatory factor analytic techniques to investigate the construct validity of the scale. The questionnaire items were developed based on theoretical considerations and the final version contained 38 items divided into 4 subscales.…

Few studies have explored the subjective mental health of adolescents with intellectual disabilities, while proxy ratings indicate an overrepresentation of mental health problems. The present study reports on the design and an initial empirical evaluation of the Well-being in Special Education Questionnaire (WellSEQ). Questions, response scales,…

A description of a method used with criterion referenced tests which is designed to reduce guessing. (HB)

This paper describes the development, utility, and validity of the Situational Self-statement and Affective State Inventory (SSASI), a research inventory designed to assess cognitions and affects across a variety of five hypothetical situations. Each situation describes a realistic incident involving interpersonal conflict, principally criticism…

The desirable characteristics of criterion referenced test items and sets of items are described. A two-stage item tryout and item selection procedure are also described. The paper presents the results of using the procedure as compared with traditional item selection procedures used in selecting items for norm referenced tests. It was found that…

In a review of instruments measuring gender-related constructs, a number of shortcomings were found in existing scales. A new scale to measure sex-role attitudes was developed and tested by first proposing the construct of sex-role egalitarianism and then initiating the process of construct validation by developing a reliable measure of the…

Although actual or projected satisfaction with parenting is important in determining whether a couple will become parents and how large their family will be, only minimal research has assessed parental satisfaction. The Cleminshaw-Guidubaldi Parent Satisfaction Scale, a 50-item Likert-type instrument designed to measure components of satisfaction…
