The current study describes the development and construct validation of a situational judgment test for assessing the strategic knowledge of classroom management in elementary schools. Classroom scenarios and accompanying courses of action were constructed, of which 17 experts confirmed the content validity. A pilot study and a cross-validation…

The purpose of this study was to determine students' perceptions about their biology teachers' attitudes and communication behaviors in classroom environment in Turkey. A Likert type questionnaire was constructed consisting of 33 statements divided to three sub-sections. The Cronbach's alpha reliability for the instrument was 0.9076. Results…

Despite the assurances of store employees, whenever a deal is on offer it always pays to apply a little logic (and mathematics) to see just how to use it most effectively. In this article, the author displays how to employ this technique by using the example of a shoe store that advertised "second pair half price" (with the fine print…

Two heuristic and three rigorous arguments are given for the fact that functions of the form Ce[kx], with C an arbitrary constant, are the only solutions of the equation dy/dx=ky where k is constant. Various of the proofs in this self-contained note could find classroom use in a first-year calculus course, an introductory course on differential…

This study presents a continuing investigation of influences on outcomes achieved by students working in groups of three on tasks related to chance and data. Earlier research described final mathematical outcomes and identified 17 factors influencing three types of short-term outcomes for groups working in an "isolated setting." The current report…

Given a set of urns, each filled with a mix of black chips and white chips, what is the probability of drawing a black chip from the last urn after some sequential random shifts of chips among the urns? The Total Probability Formula (TPF) is the common tool to solve such a problem. However, when the number of urns is more than two and the number…

This study examined the generalizability of systematic direct observation across setting and time. Participants included 14 students from an intact inclusionary fifth grade classroom. On-task/off-task behavior was directly observed using momentary time-sampling recording, twice a day, for 10 school days. Using Generalizability (G) theory, results…

This article presents two classroom episodes in which students were exposed to the value of asking questions and to the different roles played by proof in mathematics. The conversation in the two episodes is outlined in the article. The setting was a classroom of fifteen good high-school students, who were studying calculus. These episodes…

The primary purpose was to investigate the efficacy of a full year of single-sex (SS) teaching of science. The secondary aims were to locate any differentiation by set and gender, and to relate these to more proximal variables. Participants were 13 year olds. Higher set girls gave evidence of clear benefits overall, and higher set boys also,…

Teaching online is relatively new at Chicago State University (CSU). In this paper, twenty-four instructors who taught web-based, or web-enhanced courses during the spring and fall 2003 semesters CSU were surveyed about issues that they and their students had experienced in online communication. It was found that online learning was quickly…

This study involved the identification of perceptions of three groups--working students, their supervisors, and the faculty at the University of the District of Columbia--about the gap that exists between education and the world of work in the area of business communications. (Author/SSH)

Estimates a model allowing researchers to determine how much achievement on a 10th-grade standardized test can be explained by observable schooling resources and unobservable school, teacher, and class effects. Although few observable variables are significant test-score determinants, unobservable effects seem important in explaining student…

Race desegregation in Massachusetts is a major enterprise. Desegregation realigns school assignments to bring together students from residential areas that are racially different to establish a truly "common school." Programs in specific towns and cities are detailed. (BJV)

The purpose of this article is to report on a collaborative project among members of colleges of education, colleges of arts and sciences, and high school foreign language departments. The project involved conducting an online survey of 341 current foreign language teachers in Georgia in order to determine how these K?12 teachers perceived and…

A study investigated the amount of academic learning time students at several Quebec elementary and secondary schools made use of during regular physical education classes. It further explored three major time-related variables: (1) specific content area; (2) learner time engaged with relevant material; and (3) student success rate. (Authors/PP)
