This article reports the results of research to determine if a significant interactive effect exists between students' lingual background (English as a primary language [EPL] versus English as a secondary language [ESL]) and question format on students' examination scores. Students were administered examinations made up of four subtests covering the same subject matter. The subtests were composed of four question formats: multiple choice quantitative, multiple choice theoretical, open-ended quantitative, and open-ended essay questions. Based on analysis of variance and analysis of covariance, significant differences were observed between EPL and ESL students depending on the type of question on the examination. 相似文献

Undergraduate students who major in science make diverse career choices. Two such career choices are medical technologists and science teachers. One possible reason for science majors selecting different career choices might be attributed to varied personality dimensions. The purpose of this study was to identify a set of personality attributes that distinguish practicing medical technologists from practicing science teachers. The subjects of this study consisted of 83 medical technologists and 57 science teachers. Eysenck Personality (EPI) was utilized to investigate the personality attributes of subjects in terms of Eysenck's personality variable of Extroversion-Introversion and Neuroticism-Stability. Vocational Preference Inventory was utilized to investigate the vocational personality profile of subjects in terms of Holland's classification of occupations and work environment. Data with EPI revealed that there was no significant difference between medical technologists and science teachers with respect to Eysenck's personality variable of extroversion. However, there was found a significant difference between the two groups with respect to Eysenck's personality variable of neuroticism. Data with VPI revealed that there was no significant difference between medical technologists and science teachers with respect to Eysenck's personality variable of extroversion. Both the groups were characterized by the personality profile of IAS (Intellectual-Artistic-Social). This profile was different from that required earlier in literature. 相似文献

In the current climate of accountability, action research is one way for teachers to evaluate instructional changes designed to improve assessment results. It may become increasingly common for administrators to mandate teacher involvement in action research, yet few studies have been conducted in such settings. This article focuses on one middle school where the principal mandated action research for all teachers. Projects were carried out within academic departments, and department chairs were given latitude in how to organize and implement projects. This study explores project implementation and teacher perceptions of the action research. Interviews were used as an appropriate tool to explore teacher perceptions, with document analysis providing triangulation. Results from interviews of administrators, department chairs, and department members suggest an overall positive attitude toward action research, as well as variation in how action research projects were carried out. Differences occurred across several dimensions of action research, including context, motivation/ purpose, definition of action research, and organization of projects. Variations appeared to be influenced by each department chair’s experience with action research and approach to departmental work, and each department’s history of working together on instructional improvement efforts. This study suggests that administrators who mandate teacher participation in action research projects need to think about both the positive (providing teacher ownership and interest within the mandated context) and problematic (possibly leading to variation in the instructional impact of projects) aspects of project variation. 相似文献

This study examined college students’ visits to natural areas on campus and how these visits relate to place identity and environmentally responsible behaviors. The majority (76.5%) of the 115 participants visited the natural areas, and 55.7% of these students visited for a course requirement. Students who lived on campus, were younger, and majored in environmental studies, humanities, or arts made more frequent visits. Among those who had visited the natural areas (n = 88), place identity and environmental responsibility were related to visitation frequency, and were stronger for those who had visited for a course requirement. Place identity mediated the relationship between visiting for a course requirement and environmental behaviors, but did not mediate the impact of visitation frequency. 相似文献

The status of research on women and communication 总被引:2,自引:1,他引:2
The purpose of this essay is to survey and summarize the research on women, gender, and sex differences that has been published in speech communication journals. Five categories of research emerged from this survey: historical treatments of women, sex differences, images of women in the media, education and pedagogy, and surveys and integrative works. While future research is needed to fill in the gaps made evident by this survey of literature, perhaps more important is to begin to question and investigate the assumptions underlying current research about women. 相似文献

Multiple-choice (MC) reading comprehension test items comprise three components: text passage, questions about the text, and MC answers. The construct validity of this format has been repeatedly criticized. In three between-subjects experiments, fourth graders (N 1 = 230, N 2 = 340, N 3 = 194) worked on three versions of MC items from the Progress in International Reading Literacy Study 2001 reading comprehension test with relevant components successively deleted: “original version” (text, questions, MC-answers), “version without text” (questions, MC-answers), “version without text and without questions” (only MC-answers). Answering correctly the MC items became more difficult as the relevant information was eliminated. In the two narrative fictional texts presented, the students' performance of the version without text was not better than chance. Conversely in the informational (fictional) text, the students' performance of the version without text was better than chance. In the third condition, students' performance was never better than chance. 相似文献
