The primary aim of this manuscript is to describe the process of developing a reliable and valid instrument for measuring all users, including students with disabilities, sense of presence in a virtual environment. Presence can be described as feeling a part of another place other than where you are. A seven-step process is discussed and was…

Nationwide pre- and posttesting of introductory courses with the Geoscience Concept Inventory (GCI) shows little gain for many of its questions. Analysis of more than 3,500 tests shows that 22 of the 73 GCI questions had gains of <0.03, and nearly half of these focused on basic physics and chemistry. We also discovered through an assessment of…

A test was constructed to measure a person's ability to produce Spanish sounds which are considered difficult but which must be mastered for fluency in Spanish.

Emphasis was placed on the validity of test instruments in common use in the field. Since part of the practical validity of any instrument used to identify an LD child rests on the validity of the LD construct…

A self-report scale was constructed and validated that measures individual differences in objectivism--the tendency to base one's judgments and beliefs upon empirical information and rational considerations. Validity data showed that, compared to people who score low on the Objectivism Scale, highly objective individuals enjoy thinking more, rely…
