Across many of the middle- and low-income countries that have participated in the Programme for International Student Assessment (PISA) or are potential new participants, significant proportions of 15-year-olds are not enrolled in school or are in school but in grades below PISA's target sample (Grade 7 and above) and thus not eligible to sit for…

Although I am an economic geographer trained in the United States, most of my research has been conducted in Germany or Canada. Thus, I developed my disciplinary schema in a context different from the one where I now use it. This US-focused training taught me that before one examines the local dynamics of a particular industry, labor market, or…

Self-interview methods such as audio computer-assisted self-interviewing (ACASI) are used to improve the accuracy of interview data on sensitive topics in large trials. Small field studies on sensitive topics would benefit from methodological alternatives. In a study on male involvement in antenatal HIV testing in a largely illiterate population…

Much debate surrounds the issue of whether allowing candidates to listen to recordings twice is more desirable in language tests than offering just one opportunity. Using regression models, this study investigates, analyses and interconnects both item difficulty and stimulus length in relation to the frequency of stimulus presentation and its…

Teachers may use apprenticeships and collaboration as instructional strategies that help students to make authentic scientific discoveries as they work as amateur researchers in academic field studies. This concept was examined with 643 students, ages 14-72, who became proficient at field research through cognitive apprenticeships with the…

Recent National Research Council reports make compelling arguments for the need to incorporate spatial abilities and use spatial technologies throughout our educational system. We conducted a pilot study to determine the pedagogical effectiveness of teaching with geographic information systems (GIS) by using a web-based GIS tool of Indiana soils.…

This research contributes to efforts in assessment studies related to science and technology interventions. The work presented in this thesis focuses on understanding the effects of policies that influence science and technology interventions, and determining the impact of science and technology interventions themselves. Chapter 1 explores how…
