Researchers have been challenged to go beyond socioeconomic status in the search for school-level characteristics that make a difference in student achievement. The purpose of the present study was to identify a new construct, academic optimism, and then use it to explain student achievement while controlling for socioeconomic status, previous…

The actor-observer hypothesis (E. E. Jones & R. E. Nisbett, 1971) states that people tend to explain their own behavior with situation causes and other people's behavior with person causes. Widely known in psychology, this asymmetry has been described as robust, firmly established, and pervasive. However, a meta-analysis on 173 published studies…

In the statistical and transcriptional analyses reported in this exploratory study, original rhythms of 6-11-year-old children (N=36) were examined. The hypotheses were based on a new model of musical development, and tested empirically using non-pitch rhythmic improvisation in a MIDI-environment. Several representational types were found in…

Although hopelessness and depression are known risk factors for suicide, most individuals who are hopeless or depressed never make a suicide attempt. In this study, we tested the hypothesis that college students' (n = 230) attitudes toward suicide (the degree to which they see it as an acceptable option under some circumstances) would moderate the…

The experimental results of a collaborative problem solving and program development model that takes into consideration the cognitive and social activities that occur during software development is presented in this paper. This collaborative model is based on the Dual Common Model that focuses on individual cognitive aspects of problem solving and…

In 1998, California state legislation called for significant reform in the preparation of teachers. As a result, institutions of higher learning must now conduct a formal performance-based assessment. All teacher candidates must participate in the assessment at the end of the program for receipt of the preliminary teaching credential. The…

As item response theory (IRT) becomes popular in educational and psychological testing, there is a need of reporting IRT-based effect size measures. In this study, we show how the standardized mean difference can be generalized into such a measure. A disattenuation procedure based on the IRT test reliability is proposed to correct the attenuation…

This study examines the effect and validity of accommodations for limited English proficiency (LEP) students in the National Assessment of Educational Progress (NAEP) and the impact of language factors on the assessment and accommodation of these students. Results indicate that accommodations used in NAEP did not reduce the performance gap between…

The use of accommodations has been widely proposed as a means of including English language learners (ELLs) or limited English proficient (LEP) students in state and districtwide assessments. However, very little experimental research has been done on specific accommodations to determine whether these pose a threat to score comparability. This…

The main purpose of this study was to determine if online computer-based math problem-solving and paper-and-pencil math problem-solving tests are suitable tools for measuring math problem-solving, by comparing student performance on traditional style paper-based tests to performance on the same tests online. Data collection for this study was…

Recent research using theory-of-mind tasks has rekindled interest in the possibility that social interaction makes a significant contribution to cognitive development. It is proposed here that this contribution may be most pronounced with phenomena that, like belief or affective states, are internal and abstract. A more modest contribution is…

This article describes the possibilities offered by the online assessment system Etude to achieve the benefits of formative assessment. In order to find out the way this works in practice, we carried out an experiment with the use of Etude for formative assessment in the course on collaborative report writing. Results show that online formative…

This is the first of two articles that provide a critique of categorisation and of the biomedical interpretation of personal adjustment issues experienced by children and youth. In this paper the appraisal is made by the devising of an imaginary mental illness, through the presentation of some important theoretical frameworks, by considering…

Almost 20 years ago, the author wrote--and then privately published--the two "Lake Woebegone" reports, named after Garrison Keillor's mythical Minnesota town where "all the women are strong, all the men are good-looking, and all the children are above average." The first "Lake Woebegone" report documented that all 50 states were testing above the…

This paper presents a teaching methodology involving an independent research project component for use in undergraduate Comparative Vertebrate Anatomy laboratory courses. The proposed project introduces cooperative, active learning in a research context to comparative vertebrate anatomy. This project involves pairs or groups of three students…
