AbstractLinguistic awareness is crucial in learning literacy. This project has a two-fold aim: to develop the students’ ability to think about language in order to write with accuracy and to lead teachers to promote students’ discussions about their writing difficulties. The study is part of a two-year action-research project developed in primary schools from the Lisbon area, with experimental and control groups. The starting point of the project was the analysis of the problems students of third and fourth grades showed in their writing. The scope of the project includes dictation tasks within an interactionist approach, favouring grammatical discussions leading to the observation and manipulation of linguistic data. 相似文献

AbstractThis study aims to show how the integration of passive and active learning approaches contributes towards the significant understanding of problems associated with sustainable development. To do this, a case study from the municipality of San Miguel de Achiutla in Oaxaca, Mexico, is used as a general method, with the specific procedure including an instrument based on secondary sources representing the passive learning phase, as well as an instrument created on the basis of primary sources, designed in relation to the active learning component. The passive learning phase enabled us to identify variables pertaining to the highly vulnerable dimensions of sustainable development, and to also detect areas in which there is a deficit of information, since not all data are available, while the active learning phase revealed the causes of vulnerability from the perspective of different agents, including those who experienced the issues directly. In view of the above, we conclude that rather than being exclusive, these two different approaches should in fact be complementary. 相似文献

AbstractThe vast number of online educational videos available at the moment has generated an emerging area of research concerning their level of suitability. This study considers the epistemic quality of educational videos on mathematics, focusing on the specific content of directly proportional distributions. A qualitative study is used, based on the application of theoretical and methodological tools from the onto-semiotic approach to knowledge and mathematics instruction, principally the notion of epistemic suitability and the identification of algebraic levels. The sample consists of the 31 most popular videos in Spanish on YouTube? on directly proportional distributions. Analysis reveals interesting results on these kinds of resources. In general, it is observed that they are weak in epistemic suitability, which does not seem to affect their level of popularity. Moreover, the existence of videos with inaccurate arguments or incorrect procedures, together with the diversity of algebraic levels used, indicates that teachers should be careful when selecting them and only recommend those that better suit their students’ needs. 相似文献

This paper describes research on the use of knowledge models (ontologies) for building computer-aided educational software in the field of control engineering. Ontologies are able to represent in the computer a very rich conceptual model of a given domain. This model can be used later for a number of purposes in different software applications. In this study, domain ontology about the field of lead–lag compensator design has been built and used for automatic exercise generation, graphical user interface population and interaction with the user at any level of detail, including explanations about why things occur. An application called Onto-CELE (ontology-based control engineering learning environment) uses the ontology for implementing a learning environment that can be used for self and lifelong learning purposes. The experience has shown that the use of knowledge models as the basis for educational software applications is capable of showing students the whole complexity of the analysis and design processes at any level of detail. A practical experience with postgraduate students has shown the mentioned benefits and possibilities of the approach. 相似文献

The article incorporates a critical theoretical and methodological framework to study a large urban district's implementation of a court-ordered voluntary integration program through magnet school choice. Drawing on the interview data from parents and district staff, the author analyzes the data as they relate to the district's magnet school application brochure, Opportunities for Success, and how the application is designed to support the voluntary integration program. The article first presents a short historical grounding for the district's voluntary integration program and how it influences the choice options for parents. Next, it discusses how the district implemented and organized the voluntary integration program and produced the magnet school application text. It then introduces data on parents' interactions with the magnet school brochure and application. The article concludes with a discussion of what can be learned from studying the texts of a voluntary integration program, what it tells us about racial and class privilege and diverse families' access to magnet school programs, and how text analysis can help us see where, in the institutional processes of school choice, further resegregation is likely to take place. 相似文献

Research in the field of attribution theory and academic achievement suggests a relationship between a student's attributional style and achievement. Theorists and researchers contend that attributions influence individual reactions to success and failure. They also report that individuals use attributions to explain and justify their performance. Studies in mathematics education identify attribution theory as the theoretical orientation most suited to explain academic performance in mathematics. This study focused on the relationship among a high risk course, low success rates, and attribution by examining the difference in the attributions passing and failing students gave for their performance in College Algebra. Students from a large urban community college in South Florida (n = 410) self-reported their performance on an in-class test by providing open-ended attribution statements to explain the cause of their performance. They then attributed their performance along the dimensions of locus of causality, stability, personal controllability, and external controllability using the Causal Dimensions Scale (CDSII). The open-ended attribution statements were coded in relation to ability, effort, task difficulty, and luck and compared using a Pearson chi- square procedure. The quantitative data compared the passing and failing groups and their attributions for performance on the test using One-way ANOVA and Pearson chi-square procedures. The results of the quantitative data comparing passing and failing groups and their attributions along the dimensions measured by the CDSII indicated statistical significance in locus of causality, stability, and personal controllability. The results comparing the open-ended attribution statements indicated statistical significance in the categories of effort and task difficulty. 相似文献

ABSTRACTThis qualitative study examines the experiences of six Mexican community college transfer students attending a research-intensive institution in the Pacific Northwest. Using semi-structured interviews, the objectives of this study were to 1) understand how Mexican students made meaning of their transfer experiences and 2) how those experiences could inform conceptual and practical thinking toward building a transfer receptive culture at the receiving institution. We use intersectionality as a site of material and discursive possibility to encourage predominantly White receiving institutions to recognize how they position Mexican community college transfer students on campus. Concluding are conceptual and practical recommendations that emphasize institutional and organizational responsibility in creating equitable environments for Mexican community college transfer students. 相似文献

For over 30 years, researchers and practitioners have identified challenges unique to small, rural community colleges. The purpose of this study was to examine the distinctive problems facing rural community colleges today and the challenges those institutions must address to fulfill their mission in rural America. There are 5 current challenges commonly identified by 10 rural community college administrators in Kansas: technology use, grant writing, an evolving student population and corresponding changes to the mission, funding inequalities between institutions, and hiring qualified people. Identified challenges were compared with problems described in the literature from the last 30 years. 相似文献

The factor mixture model (FMM) uses a hybrid of both categorical and continuous latent variables. The FMM is a good model for the underlying structure of psychopathology because the use of both categorical and continuous latent variables allows the structure to be simultaneously categorical and dimensional. This is useful because both diagnostic class membership and the range of severity within and across diagnostic classes can be modeled concurrently. Although the conceptualization of the FMM has been explained in the literature, the use of the FMM is still not prevalent. One reason is that there is little research about how such models should be applied in practice and, once a well-fitting model is obtained, how it should be interpreted. In this article, the FMM is explored by studying a real data example on conduct disorder. By exploring this example, this article aims to explain the different formulations of the FMM, the various steps in building a FMM, and how to decide between an FMM and alternative models. 相似文献

ABSTRACTThis study aims to compare word spelling outcomes for French-speaking deaf children with a cochlear implant (CI) with hearing children who matched for age, level of education and gender. A picture written naming task controlling for word frequency, word length, and phoneme-to-grapheme predictability was designed to analyze spelling productions. A generalized linear mixed model on the percentage of correct spelling revealed an effect of participant’s reading abilities, but no effect of hearing status. Word frequency and word length, but not phoneme-to-grapheme predictability, contributed to explaining the spelling variance. Deaf children with a CI made significantly less phonologically plausible errors and more phonologically unacceptable errors when compared to their hearing peers. Age at implantation and speech perception scores were related to deaf children’s errors. A good word spelling level can be achieved by deaf children with a CI, who nonetheless use less efficiently the phoneme-to-grapheme strategy than do hearing children. 相似文献
