This paper describes part of a project called Modeling Across the Curriculum which is a large-scale research study in 15 schools across the United States. The specific data presented and discussed here in this paper is based on BioLogica, a hypermodel, interactive environment for learning genetics, which was implemented in multiple classes in eight high schools. BioLogica activities, data logging, and assessments were refined across this series of implementations. All students took a genetics content knowledge pre- and posttests. Traces of students' actions and responses to computer-based tasks were electronically collected (via a log file function) and systematically analyzed. An intensive 3-day field test involving 24 middle school students served to refine methods and create narrative profiles of students' learning experiences, outcomes, and interactions with BioLogica. We report on one high school implementation and the field test as self-contained studies to document the changes and the outcomes at different phases of development. A discussion of design changes concludes this paper.  相似文献

The federal child‐care subsidy program represents one of the government’s largest investments in early care and education, but little is known about whether it increases low‐income children’s access to higher quality child care. This study used newly available nationally representative data on 4‐year‐old children (N = 750) to investigate whether subsidy receipt elevates child‐care quality. Results indicate that subsidy recipients use higher quality care compared to nonrecipients who use no other publicly funded care, but lower quality care compared to nonrecipients who instead use Head Start or public pre‐k. Findings suggest that subsidies may have the potential to enhance care quality but that parents who use subsidies are not accessing the highest quality care available to low‐income families.  相似文献

This article describes the challenges encountered by a teacher educator and self-study practitioner as he attempted to facilitate a group of colleagues in learning about and engaging in self-study over a two year period. While competent in conducting self-study for himself, the author had never before tried to teach it to others. This led to teaching experiences in which the author grappled with his decision-making across three critical facets of his pedagogy. The findings of this self-study indicate that it is possible to broadly categorize these dilemmas in decision-making as instructional challenges, relational challenges, and methodological challenges. Uncovering and discussing these challenges gives those involved in the self-study of teacher education practices community an opportunity to consider how such dilemmas might be navigated beneficially to advance understanding and use of self-study methodology by others.  相似文献

The present study examined whether gender, ethnicity, instructional medium and school category differences manifest in science performance and motivation to learn science among secondary school students in Sri Lanka. The mean of five successive term test scores was used as the measure of science performance. Level of motivation in terms of six dimensions was measured by using the Science Motivation Questionnaire. A sample of 1316 grade 11 students representing Sinhala, Tamil, and Muslim ethnic groups from the three categories of public schools, which provide instructions in the vernacular languages of Sinhala or Tamil, participated in the study. Girls showed significantly higher performance in science compared to boys, and there was a significant gender difference in the levels of motivational dimensions in favor of girls. Although Tamil medium students possessed a higher level of motivation to learn science, Sinhala medium students outperformed their Tamil medium counterparts in science performance. Significant differences in science performance between Sinhala, Tamil, and Muslim students were also observed. However, motivation towards learning science between Tamils and Muslims was not significantly different. Highly significant differences in both motivation to learn science and performance in science were found between three categories of schools. The present study provides information to education officials who have to achieve equity across gender, ethnicity, medium of instruction, and school category, teachers who deliver the subject and school principals who design academic support programs.  相似文献

Some children learn to read accurately despite language impairments (LI). Nine- to 10-year-olds were categorized as having LI only ( n  =   35), dyslexia (DX) only ( n  =   73), LI + DX ( n  =   54), or as typically developing (TD; n  =   176). The LI-only group had mild to moderate deficits in reading comprehension. They were similar to the LI + DX group on most language measures, but rapid serial naming was superior to the LI + DX group and comparable to the TD. For a subset of children seen at 4 and 6 years, early phonological skills were equally poor in those later classified as LI or LI + DX. Poor language need not hinder acquisition of decoding, so long as rapid serial naming is intact; reading comprehension, however, is constrained by LI.  相似文献

This article reports on the English data from an international research project. Students' reports of being bullied are detailed but the main emphasis is on the role of the bystander, that is, what students did when they witnessed bullying in school and the reasons they gave for their actions. The study found that there were differences between students, in particular between primary and secondary phase students, and schools, in these areas. The responses are explored and the characteristics of those who intervened or did not. The implications for research and practice are debated.  相似文献

The relationship between students and their academic institution is based on exchange. However, we have limited knowledge regarding how many exchanges students perceive, who (or what) the perceived exchange partners are, and what the perceived terms of those exchanges contain. To address this gap, we utilized a mixed-method approach to explore and describe the psychological contracts of two sets of undergraduate university students: newly entering freshman, and experienced university students. Results clearly demonstrated that students perceive numerous psychological contracts relevant to their education with a variety of partners both inside and at the boundaries of the institution. Results also demonstrated that these contracts are qualitatively and quantitatively distinct. The overarching implication of these findings is that students navigate a web of diverse exchange partners, and it would be a mistake for educators and researchers to focus exclusively on one or few relationships presupposed to be most important.  相似文献

Have you ever seen a movie in which a building was burned down or a bridge was destroyed? Have you seen films in which a train crashed or a ship sank into the ocean? If so, you may have wondered how these things could happen without harming the people in the film.The man who knows the answer is the special-effects man. He has one of the most important jobs in the film industry. He may be ordered to create a flood or to make a battlefield explode. And he may also be asked to create a special effect which is much less exciting, though just as important to the sue-  相似文献

The study was carried out with 175 Turkish students by using drawings at different ages understanding of gene, DNA and chromosome concepts. Students from 8th, 9th, 11th grades and, science and biology student teachers were simply asked to draw the structure of gene, DNA and chromosome in a cell and also to give explanations about these three concepts. Differences in understanding between the age groups were found to be significant for the concepts of gene and DNA. None of the groups exhibit sound understanding and regardless of the age levels, students in all groups had alternative ideas about the three concepts investigated.  相似文献

This study examined how colored educational tools improve children’s numerosity (“number sense”) and/or mathematics. We tested children 6–10 years (n = 3,236) who had been exposed to colored numbers from the educational tools Numicon (Oxford University Press, 2018) or Numberjacks (Ellis, 2006), which map colors to magnitudes or Arabic numerals, respectively. In a free association task pairing numbers with colors, a subset of children spontaneously provided colors matching one of these schemas. These children, who had internalized Numicon (colored magnitude), showed significantly better numerosity but not mathematics compared to peers. There was no similar benefit from internalizing Numberjacks (colored numerals). These data support a model in which colored number tools provide benefits at different levels of numerical cognition, according to their different levels of cross-modal mappings.  相似文献

This article examines the effects of local study environments on the achievements in higher education of Dutch undergraduate students. The authors find that the grade averages, the numbers of courses successfully completed, and the drop-out rates of students vary only slightly in terms of the higher education institution attended. Most of the differences observed are the results of individual factors, i.e., differences in the ways in which students select their institutions and differences in the degree of success of their academic integration into the institutions they chose. The results indicate that when students enroll in higher education there is little benefit for them in selecting the right institution. Academic achievement is shaped mainly by individual factors.  相似文献

In interviews with over 250 urban young adolescents, many students make it clear that they are acutely aware of the educational inequities that exist in their schools and that these inequities are having a negative impact on their education. Student voice is used to highlight urban middle school students’ perspectives on the quality of their education particularly in terms of curricular issues, teacher quality, and lack of resources.
