Determining the potential of educational information and communications technology for enhancing teaching and learning is the subject of a great deal of research activity. This paper argues that the technologies employed to enhance learning can also be exploited for the enhancement of research. Recorded learner-system interactions, dynamically…

Background: Experiential learning has been posited as an approach to influencing preservice teachers' understanding of diversity and social justice. The research reported here examined the impact of a field-based experience in Poland focused on the Holocaust as it pertained to the beliefs and actions of 12 future education professionals. This…

Background/Context: In order to develop effective strategies for retaining able and committed teachers, it is important to understand how new teachers experience their work with their colleagues. A previous qualitative study conducted by the authors and others presented a conceptual framework for understanding new teachers' experiences of the…

Fluctuations in cognitive task performance in older individuals have been reported. To examine intraindividual variability as a function of practice, 34 younger and 34 older female participants, aged 20-30 years and 70-82 years, respectively, performed a reading span task 16 times over four sessions. Each individual's recall accuracy was analyzed…

The widespread problem of substance abuse negatively affects users and their families.

This testimony summarizes in four propositions results from a review of recent estimates of the net federal, state, or local costs of immigration and is designed to explore why these cost estimates vary so widely and how to develop more credible cost estimates. First, the testimony proposes that various studies of the cost of immigration agree…

Because public schools do not randomly assign students and teachers across schools (a methodological utopia), multilevel evaluation methods which account for student and school contextual and practice variables in their natural settings provide the most rigorous means for showing empirically what is actually happening in school classrooms.…

The development of curriculum frameworks for mathematics and science was an essential first step in the Third International Mathematics and Science Study (TIMSS). The frameworks have served as guides for the design of the achievement testing component of TIMSS, and as the foundation upon which the curriculum analysis component of the study is…

Only a limited number of single-subject studies exist in the literacy field, despite the upsurge of such studies in a wide variety of disciplines. The phrase "single-subject" refers not so much to the number of subjects, but to the way the data are analyzed: each subject's responses are examined individually; they are not averaged with…
