We show that boys still have a greater access to the space for interaction in science classrooms, which is unexpected since in Sweden today girls perform better in these subjects than boys. Results from video-recorded verbal communication, referred to here as interaction, show that the distribution of teacher–student interaction in the final year of lower secondary school follows the same patterns as in the 1980s. The interaction space for all kinds of talk continues to be distributed according to the two-thirds rule for communication in science classrooms as described by previous research. We also show that the overall interaction space in science classrooms has increased for both boys and girls when talk about science alone is considered. Another finding which follows old patterns is that male teachers still address boys more often than girls. This holds true both for general talk and for talk about science. If a more even distribution of teacher–student interaction is desirable, these results once again need to be considered. More research needs to be undertaken before the association between girls’ attitudes and interest in science in terms of future career choice and the opportunity to participate in teacher–student interaction is more clearly understood. 相似文献

When navigating through the vast amount of information that we encounter in our everyday lives, we constantly make decisions concerning what information to read more closely and what information to disregard. Consideration of the relevance and trustworthiness of information sources facilitates those decisions. In the present study, we interviewed 25 upper-secondary students after they had selected documents to use in completing a task, and we asked them to justify their selections. A qualitative analysis of the interview data showed that students’ justifications could be related to (1) content relevance, (2) source features, and (3) prior topic knowledge. The results demonstrate that students are able to evaluate content relevance and source features as part of their document selection strategies but that perceived prior knowledge seems to influence both selections and justifications. 相似文献

The dissociation between phonological and orthographic processes in word reading was investigated in a study involving 147 children in grade 3. The criterion measure was a timed word reading test. Two tasks assessed phonological skills and two tasks assessed orthographical skills. Orthographic ability accounted for variance in word reading even after phonological ability had been controlled. Poor readers differed from skilled readers in the way phonological and orthographic factors were balanced. The relationship between the two factors was fairly strong among poor readers, whereas the correlation was low for more skilled readers. Furthermore, phonological factors played a much stronger role in explaining the variance in word reading among poor readers, while on the other hand, orthographic factors were more powerful among skilled readers. 相似文献

At the end of Grade 4, 481 children on the Danish island of Bornholm were screened using group tests for sentence reading. For 205 of these children, language and speech data from the speech therapist's screening at age 3 were available, as well as language comprehension and linguistic awareness data from the kindergarten year (age 6) and word decoding measures in Grades 2 and 3. A path analysis revealed significant paths from early language abilities at age 3 through expressive and receptive language in kindergarten via language awareness in kindergarten and word decoding in Grade 2 to sentence reading in Grades 3 and 4. The subgroup of children with parents who had reported a history of reading problems at school entry scored significantly below average on sentence reading in Grade 4. The subgroup of children that were reported to show a very low interest in books and story reading before age 5 also scored low on sentence reading in Grade 4. Statistically significant but weak relationships were also found between parents' educational background, parents' library visits, and number of books at home and the child's reading ability in Grade 4. 相似文献

Critical thinking and skills in defining problems have been among the goals of a computers and society course that had its credits reduced and student number increased. In an attempt to prevent worsening the students' learning, four measures were taken. The results actually improved from a failure rate of 21.5% to 0.7%. This was mainly due to tighter project structure and additional student work. Reduced course material and improved teacher preparation did not seem to have any effect, while more focused project teaching may have contributed to the decreased failure rate. Further improvements may be gained through time estimation in the problem definition process. 相似文献

Electronic games are popular and many children spend much time on this activity. Here we investigate whether the quantity of time children spend on gaming is related to their social development, making this the first study to examine this relationship in children. We examine prospective relations between time spent gaming and social competence in a community sample of Norwegian 6 year olds (n = 873) followed up at ages 8, 10, and 12, controlling for socioeconomic status, body mass index, and time spent gaming together with friends. Results revealed that greater social competence at both 8 and 10 years predicted less gaming 2 years later and that more age-10 gaming predicted less social competence at age 12 but only among girls. 相似文献

This article focuses on the development of decision‐making skills and environmental concern by 11‐ and 12‐year‐old students through computer‐based, scaffolded learning activities. The enacted activities provided necessary scientific information and allowed for the consideration of multiple aspects of the problem, the study of the effects of every possible solution and the formulation and balancing of criteria. The optimization strategy for decision making was adopted, because it allows for the development of compensatory thinking which is more relevant to actual situations of decision making. Twelve students participated in the pilot enactment of the proposed activities. Data collection relied on students’ reports and pre‐ and post‐ tests as well as a closed questionnaire designed to measure students’ environmental concern. The teaching intervention proved quite successful in enhancing the decision‐making skills of the participating children. Moreover, students’ performance on the environmental concern questionnaire correlated in interesting ways with the improvement of decision‐making skills. 相似文献
