German readers would immediately associate the term ‘discipline-based’ with Didaktik, which in the German-speaking world is an established branch of education science. The first section therefore deals with the development of Didaktik, understood as a theory of teaching and learning which seeks to investigate the relationships between discipline-based and general teaching theories. Didaktik was originally a strictly theory-oriented discipline in German-speaking countries, but changes in its terms of reference have led to an acceptance of the more pragmatically oriented curriculum theory of the English-speaking world. The term ‘discipline-based’ seems to indicate that here, too, education science has turned its back on positivistic, ‘purely scientific’ standards, so a knowledge of the German discussion of teaching-learning theory may be of interest.
The second section shows that in distance education, too, general teaching models need concretization in terms of discipline-based teaching theory, and that on the other hand, any discipline-based theory needs to have its foundations in general teaching theory, i.e. in pedagogic principles.
The third section therefore postulates the necessity of a theory of distance education which is based on practical experience. 相似文献
Gender differences in educational outcomes are often reported. However, some evidence suggests that these differences are not consistent but vary with social background. In quantitative research, however, the interaction between gender and social background has been underinvestigated. The present study investigates whether the effect of gender on achievement is moderated by socio-economic status (SES). The sample consists of N = 3935 primary school-children in Berlin (6th grade). The results show that the effect of gender on achievement varies with SES, with a stronger correlation between the achievement of boys and their SES. Taken together, the results of the study suggest a differentiated consideration of the achievement of boys and girls and the importance of considering multiple group identities. 相似文献
AbstractConstant pressures emanating from internal and external environments of the academy have resulted in many changes, one of which is the workplace mobbing, an old issue for the broader field of organization science but a relatively new phenomenon in the academic context. This study investigated the relationship between workplace mobbing and academic leadership and the results indicated that the more positive leadership there is in an institution, the less mobbing behaviors are observed. 相似文献
Background: One of the topics students have difficulties in understanding is electromagnetic induction. Active learning methods instead of traditional learning method may be able to help facilitate students’ understanding such topics more effectively.
Purpose: The study investigated the effectiveness of physical models and simulations on students’ understanding daily life applications of electromagnetic induction.
Sample: The nine participants in the study were voluntaries from the fourth year of the physics education undergraduate programme.
Design and methods: Lessons were designed to enhance students’ conceptual understanding of electromagnetic induction. Researchers developed multiple generator and simple electric motor models. These models and simulations about Faraday’s Law, magnetic field, magnets, generator and radio waves were used in lessons. The data were collected through open-ended questionnaire and semi-structured interview. Open-ended questionnaire was employed in a pre-test and a post-test. Students’ answers were categorized as sound understanding, partial understanding, misunderstanding and no understanding. At the end of the last lesson, the interview was implemented about the students’ opinions related to application.
Results: For each question, the number of responses matching the accepted scientific explanation increased after application. The number of illogical or incorrect responses decreased.
Conclusions: Physical models and simulations used in the present study had positive effect on students participated in this study to understand electromagnetic induction and its daily life applications. 相似文献
Senior pre-university education (SPE) students experience difficulties applying mathematics to physics. This paper reports the outcome of an online explorative quantitative study of teachers' belief systems about improving transfer of algebraic skills from mathematics into physics, conducted among 503 mathematics and physics teachers working in SPE. We used a questionnaire with 16 beliefs about improving transfer, and asked teachers to select a top 5 and distribute 50 points among them. We used agglomerative hierarchical clustering to cluster qualified SPE teachers with more than 10 years of teaching experience. We found 3 large clusters, each containing naïve and desirable beliefs about transfer. These clusters turned out to be rather coherent sets of beliefs. Hence, these clusters can be interpreted as belief systems, to a certain extent justifying Ernest's [(1991). The philosophy of mathematics education. London: Falmer.] idea to cluster teachers based on their belief systems. We found relations between our groups and those of Ernest. Since naïve beliefs turn out to be weak in each cluster, science teacher educators can help science teachers to change their harmful naïve beliefs, into desirable transfer enhancing beliefs. Furthermore, we discuss some implications of our results for science teacher educators, curricula, teachers and textbooks. 相似文献
The aim of this study is to explore the effects of a coping skills training program on stress, and hopelessness levels and coping skills of mothers of children with autism the age range of children was 12–19 for the experimental group and 11–17 for the control group. Twenty mothers of children with autism were assigned to a treatment group and a no treatment control group. A pre-test- post-test no-treatment control group design was undertaken. After completion of the program, interviews were conducted with the mothers in the experimental group to get some qualitative data about the effectiveness of the program. The results revealed differences in hopelessness levels and the use of social support as a coping strategy; however, there was no significant difference in the use of avoidance and problem solving as a coping strategy and stress levels of mothers. Moreover, the interviews conducted with mothers indicated a positive effect of the program on the mothers of children with autism. The generalization of the results is limited as the sample consisted of ten mothers and long-term follow-up data were not collected. 相似文献
ABSTRACTThe World Wide Web has become a major information resource for adolescents (i.e., 10–19 years of age), offering an unprecedented amount of information on virtually any topic. While the Web can potentially offer new learning opportunities, it also presents several challenges. Reading and learning on the Web requires a set of advanced literacy skills that adolescents do not necessarily possess and need to develop in order to effectively deal with the complexity of information encountered online. This special issue brings together five empirical articles and a discussion paper that examine internal and external factors that are beneficial (or detrimental) to adolescents’ reading and learning on the Web, and contribute to explaining how young learners develop complex literacy skills. Theoretically, the special issue contributes to the conceptualization of what researchers refer to as ‘multiple documents literacy’. In practice, it informs researchers and educators of emerging empirical results regarding adolescents’ information behaviour, as well as on instructional strategies that can be effective for developing adolescents’ literacy skills. 相似文献
For many students, school is a place that makes no sense; a place where students’ interests are not reflected in the curriculum. Using mixed methods research, we developed an instrument that identifies student interests. This instrument was applied in a pilot study that considered 10th-grade students from three schools in Santiago, Chile. We compared student interest and national curriculum for different factors and established how well aligned these are. The results reveal that private school students prefer subjects that require greater cognitive development, related to Young’s powerful knowledge. Students from voucher schools, on the other hand, prefer to develop their knowledge of the arts and physical education, both of which are subjects they tend to enjoy. These findings are coherent with Bernstein’s theories. This pattern is also repeated when comparing high-performing students with their low-performing counterparts, regardless of school type. The findings of this study not only help identify which subjects the students want to study, but also to understand the reasons behind their preferences. Understanding these reasons is key for developing a more contextualised curriculum that makes more sense to the students. 相似文献
