This paper describes a method for scaling and reporting test results when comparing different types of mathematics instruction with small groups (often the case in studies with special populations). Results are compared for an instructional experiment with remedial and nonremedial students using a number-correct scoring and a standardized score…

Discusses the theory of microeconomic efficiency measurement, including frontier efficiency-measurement techniques; reviews the research measuring inefficiency in education; discusses the determinants of educational efficiency; includes table listing author, methodology, inputs and output, analytical techniques, and main findings for 28 studies of…

Describes a yearlong project to develop and implement new approaches to instruction in the study of biology. An engaged learning methodology was employed to collaboratively integrate technology into classrooms across educational institutions, second grade through higher education. Presents qualitative and quantitative research findings. (LRW)

Experimental study of the effect of computer-assisted career guidance program on career development of South Korean 9th- and 11th-grade students measured by pre-post test scores on instrument to determine career-conscious development of adolescents. Finds significantly higher mean posttest career-conscious scores in experimental group. One of…

Presents the results of a study comparing Spanish and mathematics scores of Chilean eighth grades in six types of public and private schools. Controlling for student and peer attributes, the initial results suggest that the average student scored higher on Spanish and mathematics tests in private nonvoucher schools than in the other types of…

As people with HIV live longer and healthier lives, ongoing prevention with positive individuals has become a new focus of care. Effective prevention with positives interventions are emerging and new interventions continue to be developed. This article discusses the development and evaluation of the prevention for positives intervention developed…

Reflected self-appraisal suggests that individual functioning is related to the fit between individual characteristics and the norms of their primary contexts. To apply this social psychological concept to the study of obesity, we hypothesized that adolescents at risk of obesity would have lower academic achievement overall than other students,…

One of the most crucial roles of the school leader is to develop and maintain the professional level of the staff which he/she supervises. It is generally agreed upon that the desired school culture is one in which the focus is on the development of a community of learners. Consequently, intellectual growth can never happen for children unless it…

The authors show how the work of Nobel Laureates in economics can enhance student understanding and bring them up to date on topics such as probability, uncertainty and decision theory, hypothesis testing, regression to the mean, instrumental variable techniques, discrete choice modeling, and time-series analysis. (Contains 2 notes.)

Higher education (HE) in Germany and the United Kingdom is being continually subjected to the discipline of market forces. An empirical study was conducted using questionnaires with academic staff in 12 institutions in each country to discover the extent to which their values and attitudes were converging and were in keeping with what might be…

Empirical studies demonstrated Type-I error (TIE) inflation (especially for highly discriminating easy items) of the Mantel-Haenszel chi-square test for differential item functioning (DIF), when data conformed to item response theory (IRT) models more complex than Rasch, and when IRT proficiency distributions differed only in means. However, no…

This study investigated their views concerning evidence and expert opinion of 10th-grade students, accessed by an open-ended questionnaire in the context of a socio-scientific issue: the cause of flood disasters, and personal epistemology identified by the "Learning Environment Preference Questionnaire" (LEP). Students' responses to the open-ended…

It is well-known that for normally distributed errors parametric tests are optimal statistically, but perhaps less well-known is that when normality does not hold, nonparametric tests frequently possess greater statistical power than parametric tests, while controlling Type I error rate. However, the use of nonparametric procedures has been…

This paper reports an investigation of the impact of students cognitive style on their effective use of educational text-based computer-mediated conferences. The research centres on an empirical study involving students from three courses run by the British Open University. Statistical analysis of the data does not suggest that cognitive style has…

Although there is an increased risk of schizophrenia-spectrum psychoses (SSP) in people with intellectual disability (ID), there is a paucity of research evidence into clinical presentation of the disorder in comparison with research into SSP in people without ID. Aims The aims of the study were to compare clinical, functional, and social factors…
