Students’ conceptions and beliefs about learning are constructs that have been proposed in two independent lines of research, phenomenographic and metacognitive, and analysed using qualitative and quantitative methodologies, respectively. The present research examines and integrates in a single study both constructs and methodologies. Data were collected through an open-ended task (Tynjäla, 1997) and an epistemological questionnaire (Schommer, 1990), administered to a sample of 1,200 secondary students. Three major statistically significant findings emerged. First, students’ conceptions of learning and epistemological beliefs changed from simplistic to more complex as they progressed through school. Second, the two constructs were linked to each other. The most advanced category on the ‘dimension of depth’ of learning conceptions corresponded to the highest scores at the complex pole of the belief system. Third, learning conceptions as well as epistemological beliefs were predictors of academic performance. The more capable students were of constructing meaning, the better their academic achievement appeared to be. Theoretical and educational implications are discussed with regard to further research, classroom instruction, and the value of combining both research methodologies in order to deepen our understanding of students’ learning experience.  相似文献

The paper presents the findings of a mixed-methods study investigating the perceptions of business students in the Czech Republic towards entrepreneurship education, and examining the factors influencing their level of intention to be entrepreneurs. The results indicate that family background significantly influences the student’s entrepreneurial intention, and that participation in entrepreneurship-oriented courses positively influences the student’s level of self-efficacy. The study revealed further that business education had some effect on the student’s ability to gain the necessary knowledge for entrepreneurship. Another key finding was that entrepreneurship education specifically for business students has to equip students with entrepreneurial skills, attributes and behaviours. The results also suggest that entrepreneurship education is a contextually determined concept which requires modification of content and methods to meet the specific needs of particular target groups. The study has important implications for higher education institutions in terms of designing and managing effective entrepreneurship education.  相似文献

What strategies help ethnic minority adolescents to cope with racism? The present study addressed this question by testing the role of ethnic identity, social support, and anger expression and suppression as moderators of the discrimination–adjustment link among 269 Mexican‐origin adolescents (Mage = 14.1 years), 12–17 years old from the Midwestern U.S. Results from multilevel moderation analyses indicated that ethnic identity, social support, and anger suppression, respectively, significantly attenuated the relations between discrimination and adjustment problems, whereas outward anger expression exacerbated these relations. Moderation effects differed according to the level of analysis. By identifying effective coping strategies in the discrimination–adjustment link at specific levels of analysis, the present findings can guide future intervention efforts for Latino youth.  相似文献

Background Argumentation is an important discourse process in science that needs to be taught and learned as part of a repertoire of strategies to support the acquisition of scientific literacy. Research in science education indicates that beliefs or perceptions and the epistemological orientations of teachers influence their approaches to science teaching.

Purpose The paper aims to illustrate primary pre-service teachers’ understanding of argumentation based on a study using quantitative methodology. In particular, it aims to illustrate how these teachers view quality of arguments and teaching strategies related to argumentation in the context of a socio-scientific issue on energy.

Sample 332 pre-service teachers enrolled in a university teacher education programme in Spain were investigated. Many studies on argumentation have been conducted with small sample sizes of teachers. Hence, given the sample size, the study provides findings that are likely to be generalisable.

Design and methods A questionnaire was administered to the participants. The design of the questionnaire was guided by some existing analytical tools which were adapted for primary education purposes in the context of socio-scientific issues. This adaptation is novel in that the questionnaire items can potentially be used as diagnostic questions to assess primary teachers’ understanding of argumentation.

Results The results suggest that pre-service teachers had difficulty in understanding arguments and different pedagogical strategies to promote argumentation in classroom. For example, they did not understand the role and the meaning of warrants in scientific arguments and their understanding of the use of different kind of strategies is limited to debates, open discussions and experiments. The age range of the participants and the length of teaching experience had no impact on the quality of their understanding of argumentation.

Conclusions Pre-service science teacher education will benefit from incorporation of more robust and lengthy sessions on argumentation. For example, sessions could focus on quality as well as structure of arguments in science and more diverse pedagogical strategies to support argumentation in science lessons, such as the use of writing frames and presentations.  相似文献

The objectives of this study are:(1) evaluation of the methodology used in recent search for particles with fractional electrical charge (quarks) and its implications for understanding the scientific research methodology of Millikan; (2) evaluation of 43 general physics textbooks and 11 laboratory manuals, with respect to the oil drop experiment, based on seven history and philosophy of science criteria. Results obtained show that all the textbooks and manuals ignored the Millikan–Ehrenhaft controversy and in general lacked a history and philosophy of science perspective. In spite of the anomalous data, Millikan adhered to the guiding assumptions of his research program. Ehrenhaft's work strictly followed the logic of experimental observations. Although, Ehrenhaft's work approximated the traditional scientific method, the scientific community supported Millikan. General physics textbooks and laboratory manuals present the oil drop experiment as an example of the scientific method in which experimental data implicitly serves as an arbiter in the defense of Millikan. It is suggested that textbooks and manuals by including the Millikan–Ehrenhaft controversy and the methodology used in the search for quarks could enrich students' understanding of scientific research methodology, viz., experimental data do not always dictate the choice of a theory.  相似文献

Studying metaphor with students from similar fields but from different specializations may seem an overwhelming experience. However, the use of a contextualized poster where the images are more important than the actual words has demonstrated how the use of images in the classroom is a valuable tool. Analysis of a questionnaire handed out to a sample of 'English for Specific Purposes' students confirmed these conclusions. The following paper deals with the pedagogical implications that the use of a poster has proved to have with a multidisciplinary group of students.  相似文献

In this article we present a general approach not relying on item response theory models (non‐IRT) to detect differential item functioning (DIF) in dichotomous items with presence of guessing. The proposed nonlinear regression (NLR) procedure for DIF detection is an extension of method based on logistic regression. As a non‐IRT approach, NLR can be seen as a proxy of detection based on the three‐parameter IRT model which is a standard tool in the study field. Hence, NLR fills a logical gap in DIF detection methodology and as such is important for educational purposes. Moreover, the advantages of the NLR procedure as well as comparison to other commonly used methods are demonstrated in a simulation study. A real data analysis is offered to demonstrate practical use of the method.  相似文献

In this paper, the application of Bayesian networks to student modeling is discussed. A review of related work is made, and then the structural model is defined. Two of the most commonly cited reasons for not using Bayesian networks in student modeling are the computational complexity of the algorithms and the difficulty of the knowledge acquisition process . We propose an approach to simplify knowledge acquisition. Our approach applies causal independence to factor the conditional probabilities and decrease the parameters required for each question to a number linear in the number of concepts. This also provides the new parameters with an intuitive meaning that makes their specification easier. Finally, we present an example to illustrate the use of our approach.  相似文献

This Grounded Theory study utilized Self-determination Theory to analyze the interview results of 18 community college African American and Latino males. The goal was to learn what helped participants to succeed and persist in developmental and transfer-level writing courses despite the obstacles that they faced. Three major themes emerged: (a) Male students of color continued to take and complete English courses because they were determined to achieve their academic goals; (b) they sought assistance and guidance from their English professors, from the writing lab attached to the basic skills course and from the writing tutoring staff; and (c) when they felt overwhelmed and considered dropping their English classes, their determination to achieve their goals and the assistance they received from faculty and other writing staff ultimately kept them from doing so. Therefore, first, community colleges should encourage students’ ability to be autonomous. Second, they can help students develop a sense of relatedness by providing a better sense of belonging. Third, institutions should develop strong faculty networks within the college to increase student motivation and self-determination by providing mentoring opportunities. Finally, institutions should consider utilizing faculty and other institutional agents to help students by providing information regarding various student support services that may help address issues students may be encountering.  相似文献
