This study examined the role of computer-supported knowledge-building discourse and epistemic reflection in promoting elementary-school students’ scientific epistemology and science learning. The participants were 39 Grade 5 students who were collectively pursuing ideas and inquiry for knowledge advance using Knowledge Forum (KF) while studying a unit on electricity; they also reflected on the epistemic nature of their discourse. A comparison class of 22 students, taught by the same teacher, studied the same unit using the school’s established scientific investigation method. We hypothesised that engaging students in idea-driven and theory-building discourse, as well as scaffolding them to reflect on the epistemic nature of their discourse, would help them understand their own scientific collaborative discourse as a theory-building process, and therefore understand scientific inquiry as an idea-driven and theory-building process. As hypothesised, we found that students engaged in knowledge-building discourse and reflection outperformed comparison students in scientific epistemology and science learning, and that students’ understanding of collaborative discourse predicted their post-test scientific epistemology and science learning. To further understand the epistemic change process among knowledge-building students, we analysed their KF discourse to understand whether and how their epistemic practice had changed after epistemic reflection. The implications on ways of promoting epistemic change are discussed. 相似文献

Learning difficulties have been found to dilute the possibilities that young adults have in their educational careers. However, during the last few decades, education has become increasingly important for employment and overall life satisfaction. In the present study, we were interested in the effects of mathematical and reading difficulties and socioemotional and behavioural problems (measured at age 16) on three educational situations at age 21: delayed graduation from upper secondary education, short educational trajectory and not being engaged in education, employment or training (NEET). The participants (N = 597; 304 females, 293 males) were one age cohort of ninth graders in general education classes, who were followed for five years after completion of compulsory education. This time frame included two different transition phases: first, from comprehensive education to upper secondary education, and second, from upper secondary education to further studies or to working life. Structural equation modelling was used as analysis method. The findings show that mathematical and reading difficulties as well as socioemotional and behavioural problems had significant long-term effects on the participants’ educational careers. New in part was that these learning difficulties seemed to have somewhat divergent emphases on the three investigated life situations: (1) mathematical difficulties, more strongly than reading difficulties, caused the students to attain lower levels of education, (2) mathematical difficulties and socioemotional problems predicted a student ending up in the NEET group and (3) reading difficulties and behavioural problems predicted delayed graduation from upper secondary education. 相似文献

Institutions of higher education are looked to by society as the training grounds and gatekeepers for college-trained workers.
However, despite a long history of being viewed by many as unresponsive to labor force needs, the academy has not found ways
of effectively meeting these demands, nor articulating why it is that they have difficulty doing so. This paper discusses
how institutional researchers can help explain to campus administrators and others the role that institutions play in training
individuals for the workplace, and why they cannot always quickly respond to and solve shortages of college-trained workers.
The first section outlines what economic theory and research has to say regarding labor markets, how labor market shortages
arise, and how students make decisions about which major to pursue. The last section describes problems institutional researchers
face when using their skills with data to identify solutions to this problem. Using data from the state of New Hampshire,
it will be shown that the data available to institutional decisionmakers can be out of date, inaccurate, and not particularly
useful for designing policies that would enable an institution to respond to the labor needs of the economy. 相似文献

International cooperation in history teaching and related teacher education requires clarification of terminology as well as of underlying concepts and theoretical foundations, since these levels are fundamentally intertwining. If these levels are addressed, both comparison and translation do not only make cooperation possible, but promise valuable contributions to the clarification of such concepts on either side. Being the German counterpart to the viewpoint of Peter Seixas, this article both corroborates and adds to his reflections. Three complexes of theory and terminology are addressed: ‘Geschichtsbewusstsein’ (‘historical consciousness’) with special regard to the concept of ‘Sinnbildung’ in Jörn Rüsen’s theory, the German focus on the concepts of source (‘Quelle’) compared to the Anglosaxon concept of ‘evidence’ and the challenges posed by translating Jörn Rüsen’s concept of ‘Triftigkeiten’ (plausibility) as a criterion for assessing the quality of historical statements. 相似文献

Relational Aggression, Overt Aggression, and Friendship 总被引:18,自引:1,他引:18
This study ( n = 315 9–12-year-olds) was conducted to assess whether the social problems that relationally and overtly aggressive children typically experience in the peer group context are also exhibited in the dyadic, friendship context. The qualities of children's friendships (e.g., levels of intimacy) and of the importance of those qualities (e.g., the importance of intimacy) were assessed with self-report instruments adapted from past research. Results indicated that the friendships of relationally aggressive children were characterized by relatively high levels of intimacy, exclusivity/jealousy, and relational aggression within the friendship context. In contrast, the friendships of overtly aggressive children were characterized by engaging together in aggressive acts toward those outside the friendship. In addition, overtly aggressive children placed relatively high importance on these coalitional acts and on companionship with their friends. Implications for our understanding of aggressive children and for our knowledge of children's friendships are discussed. 相似文献

The motivated strategies for learning questionnaire (MSLQ) is widely used as a self-report instrument to assess students’ motivation and self-regulation. This study utilized the MSLQ Junior High to examine the motivational beliefs and self-regulation of secondary school students (Grades 8 and 9) from Singapore. The instrument was slightly modified and administered to students (N?=?610) in mathematics and science classes. In the first sample, 314 students completed the MSLQ Junior High while a second sample of 296 students completed the revised MSLQ Junior High. Using a congeneric approach of confirmatory factor analysis (CFA), the five-factor measurement model was determined with the first sample. This measurement model was further supported using a second sample and its goodness-of-fit indices were compared with other CFA models. Statistical findings showed that the five-factor structure of the revised MSLQ Junior High had a good model fit. The present study contributes a novel methodological approach by investigating the parsimony confirmatory factor structure of the revised MSLQ Junior High in local academic contexts. 相似文献

Presenting narrative text in computer-based instruction (CBI) is more difficult than in print lessons due to limited screen
resolution and display area. The present research aimed at achieving a more compatible match between lesson content and the
attributes of the presentation media. Subjects received either a print or CBI statistics lesson containing low-density (concise)
narrative text, high-density (conventional) text, or the density type they preferred (learner-control). Results showed the
low-density lesson to reduce completion time relative to the high-density version, while yielding equivalent achievement.
Subjects receiving the lesson in the print mode had shorter completion times and higher achievement than their CBI counterparts.
Attitude results showed that CBI was favorably regarded, but perceived as longer and slow-moving than print. Implications
of results for designing instructional material in accord with CBI attributes and learner characteristics are discussed. 相似文献
