The study focused on the interaction between two secondary school students while they were working on computerized mathematical
investigation tasks related to probability theory. The aim was to establish how such interaction helped the students to learn
from one another, and how it may have hindered their learning process. The assumption was that interaction is beneficial for
students if they can perform certain key activities, namely showing, explaining, justifying, and reconstructing their work.
Both students attained mathematical level raising. However, the student who explained frequently and criticized himself attained
more mathematical level raising than the student who did not explain her work frequently or criticize herself. 相似文献

The Course-Faculty Instrument (CFI) demonstrates similar measurement properties with student populations at four diverse institutions. These students agree about the nature and extent to which course and instructor attributes relate to their learning. The results suggest that: (1) a perceived learning criterion may have general relevance to students, and (2) validity extension research is an economically feasible alternative to full-scale instrument development and validation efforts. Since validity extension is practical and facilitates cross-institutional comparisons, it appears to be a more viable strategy for researching and instituting student evaluation systems than is suggested by its current usage. 相似文献

Legislative activity and controversy concerning the issue ofhomosexual rights and practices has intensified in Britain overthe last decade. Despite this increase in intensity, however,the question of mass public opinion in relation to homosexualrights and practices has received little empirical investigation.In an effort to remedy this situation, this paper focuses onthe influence of party identification in determining publicattitudes towards homosexuals. Using data from the British SocialAttitudes Surveys, the results suggest that although party identificationexerts an independent and statistically significant effect onattitudes towards homosexuals, in all cases, however, theseeffects are both secondary and variable. Other equally, if notmore salient, determinants include: gender, education, age,occupation, and type of homosexual relationship. Of these varioussociodemographic variables, both age and education standout as having the strongest and most consistent effect. In otherwords, at least as far as current British society is concerned,anti-homosexual views are most prevalent among both older individualsas well as the lesser educated. 相似文献

PurposeThe purpose of this study was to examine effects of a sport version of a semi-rigid ankle brace (Element?) and a soft ankle brace (ASO) on ankle biomechanics and ground reaction forces (GRFs) during a drop landing activity in subjects with chronic ankle instability (CAI) compared to healthy subjects with no history of CAI.MethodsTen healthy subjects and 10 subjects who had multiple ankle sprains participated in the study as the control and unstable subjects, respectively. The CAI subjects were age, body mass index and gender matched with the control subjects. The arch index and ankle functions of the subjects were measured in a subject screening session. During the biomechanical test session, participants performed five trials of drop landing from 0.6 m, wearing no brace (NB), Element? brace and ASO brace. Simultaneous recording of three-dimensional kinematic (240 Hz) and GRF (1200 Hz) data were performed.ResultsThe CAI subjects had lower ankle functional survey scores. The arch index and deformity results showed greater arch deformity of Element? against a static load than in NB and ASO due to greater initial arch position held by the brace. CAI participants had greater eversion velocity than healthy controls. The ASO brace reduced the first peak vertical GRF whereas Element? increased 2nd peak vertical GRF. Element? brace reduced eversion range of motion (ROM) and peak eversion velocity compared to NB and ASO. In addition, Element? reduced dorsiflexion ROM and increased peak plantarflexion moment compared to NB and ASO.ConclusionResults of static arch measurements and dynamic ankle motion suggest that the restrictions offered by both braces are in part due to more dorsiflexed ankle positions at contact, and higher initial arch position and stiffer ankle for Element?. 相似文献

This article describes the construction of a hierarchical taxonomy of metacognitive activities for the interpretation of thinking-aloud protocols of students in secondary education, who studied texts on history and physics. After testing an initial elaborate taxonomy on a restricted number of protocols by multiple raters, it appeared that the interrater correspondence was well below par. The categories in the taxonomy were too highly specified. Categories were combined and tested on new protocols in a cyclic fashion. The revised taxonomy was then used for coding 16 history protocols and 16 physics protocols. Frequencies of occurrence of metacognitive activities were obtained, as well as judgements of the quality of the metacognitive activities of the participants. There is a reasonable correlation between the frequency method and the quality method for coding thinking-aloud protocols. Also, there is a substantial covariation of the number of metacognitive activities across both tasks. 相似文献

Several usability issues were encountered during the design of a blended e-learning program for a course in evidence-based medicine for general practice trainers. The program was developed in four steps. We focused in this article on step 2 and 3. Step 2 focused on which educational principles to apply, that is, which learning theories, instructional designs and other theories should influence the program. Step 3 focused on the design elements, namely whether to use hypermedia and/or multimedia, and what screen design and which font to use. This article presents the important issues in designing an e-course and provides an impression of the complexity of designing high quality e-learning in particular for continuing medical education (CME). 相似文献

This article is a follow-up to an earlier article (Bednarz and Janvier, 1982) which presented the results of a research study on the understanding of numeration by primary school children. That study pointed out the main difficulties children meet in learning numeration, presented a theoretical framework that made explicit a conception of numeration different from the one considered in current mathematics teaching, and also proposed a reference framework utilizable for learning and evaluating this notion. The experimentation in a classroom announced at the end of the article, was undertaken from 1980 to 1983 with the same group of children from the time they were in first grade (6–7 years old) to the third grade (8–9 years). The theoretical and reference frameworks developed in the former research study proved to be effective for developing a constructivist approach leading children to build a meaningful and efficient symbolism of number.This article is mainly devoted to presenting the results of this three year longitudinal study (part C). At first, we shall characterize briefly our intervention based on a constructivist approach of numeration (part A). Also we shall describe the conditions under which the experimentation was carried out, and the means used to evaluate the impact on the pupils (part B). 相似文献

Problem-solving skills and understanding of domain, knowledge (e.g., fighting misconceptions) are important goals in both
secondary and tertiary science education. A prototype of an instructional task is presented which aims at improved problem-solving
skills based on understanding of domain knowledge. In this task, comparing carefully selected solved problems by groups of
students is utilised as a learning activity for the acquisition of adequate problem schemata. The task is designed as a part
of the so-called UBP-program (UBP=Understanding Based Problem solving) currently being developed, for education in science.
The result of an evaluative study for the field of mechanics is presented. The UBP-task appears apt to improve problem-solving
skills at a less advanced level of physics education (e.g., 10th grade), especially for students normally performing poorly—who
are often girls. 相似文献

Controversy concerning the issue of homosexual rights and practiceshas intensified in Britain over the last decade. Despite thisincrease in intensity, however, the question of mass publicopinion in relation to homosexual rights and practices has receivedalmost no empirical investigation. In an effort to remedy thissituation, this article focuses on both the role of respondents'gender as well as their perceptions concerning the gender ofparticipants in a homosexual relationship (both sexes versusgay men) in distinguishing their attitudes toward the publicacceptance of homosexuals and the adoption rights of lesbiansand gay men. Using nationally representative data from the BritishSocial Attitudes Surveys, we found that, whereas both respondents'gender and the gender of participants in a homosexual relationshipdemonstrated a significant influence on attitudes toward thepublic acceptance of homosexuals, they were unrelated to theadoption rights of lesbians or gay men. Even in relation tothe public acceptance of homosexuals, however, gender was notthe only, or even the most important, attribute in distinguishingindividual opinion in this instance. Other stronger and moreconsistent influences were education, age, and attitudes towardeither pre-marital or extra-marital sexual relations. The implicationsof these findings for both policy makers and homosexual activistsare discussed. 相似文献
