Most students enter their first university physics course with a system of beliefs and intuitions which are often inconsistent with the Newtonian frame of reference. This article presents an experiment of collaborative learning aiming at helping first-year students in an engineering programme to transition from their naïve intuition about dynamics to the Newtonian way of thinking. In a first activity, students were asked to critically analyse the contents of two video clips from the point of view of Newtonian mechanics. In a second activity, students had to design and realise their own video clip to illustrate a given aspect of Newtonian mechanics. The preparation of the scenario for the second activity required looking up and assimilating scientific knowledge. The efficiency of the activity was assessed on an enhanced version of the statistical analysis method proposed by Hestenes and Halloun, which relies on a pre-test and a post-test to measure individual learning. 相似文献

Researchers suggest that certain supportive behaviors of mentors could increase the benefits of school-based mentoring for youth. However, the literature contains few validated instruments to measure these behaviors. In our present study, we aimed to construct and validate a tool to measure the supportive behaviors of mentors participating in school-based mentoring programs. The mentor behavior scale (MBS) was developed drawing on the premises of the mentoring sociomotivational model. Two hundred and fifty-three (253) college students participating in an eight-month school-based mentoring program completed an experimental version of the MBS and different measures of the quality of the mentoring relationship at two times during the program. The questionnaire has good internal consistency coefficients and adequate factorial structure, with the exception of the factor autonomy support. Moreover, three dimensions of the MBS predict mentoring relationship quality and the perceived usefulness of the intervention. Recommendations for the use and improvement of the MSB are proposed. 相似文献

Three experiments compared the learning potential of text versus outline and matrix displays. In Experiments 1 and 2, college students read or heard a passage about fish and then studied the text, an outline, or a matrix. In Experiment 3, students heard a passage about wildcats, and then studied text, outline, or matrix displays. In all experiments, the text, outline, and matrix formats were informationally equivalent. However, the two-dimensional matrix appeared more computationally efficient than the linear organized text or outline because it (a) positioned related information about fish or wildcats in closer proximity so that local relations within a single category (such as size) were learned, and (b) organized information spatially so that global relations across categories (such as size and diet) were learned. The learning potential of text, outline, and matrix displays was also examined in combination with variations in thematic organization, amount of study time, and time of testing. The most important and consistent findings were that (a) outline and matrix displays produced greater relational learning than the text, and (b) matrix displays produced greater relational learning than outlines. 相似文献

This study focuses on the teachers’ predictions of the students’ performances – in particular the middle-low achievers – while solving tasks testing inquiry competencies. The tasks come from PISA science. More specifically we study science teachers’ predictions for several aspects: levels of difficulty of the tasks, the potential sources of difficulty and the potential difficulty in solving it for medium-low achievers. We also study what assessed competencies are identified by science teachers in the tasks. Our approach is a questionnaire-based study. A sample of French teachers in science and technology (125) responded to the questionnaire. The teachers show a rather good ability to predict inquiry task levels of difficulty for medium-low achievers and are able to identify relevant potential sources of difficulty or easiness in the items. However, they are not aware of some essential difficulties that medium-low students encounter while solving science inquiry tasks. Moreover, the teachers have difficulty identifying the competencies that are tested by an item. 相似文献

Morphological awareness in developmental dyslexia 总被引:5,自引:0,他引:5
This study examines morphological awareness in developmental dyslexia. While the poor phonological awareness of dyslexic children
has been related to their difficulty in handling the alphabetical principle, less is known about their morphological awareness,
which also plays an important part in reading development. The aim of this study was to analyze in more detail the implications
of the phonological impairments of dyslexics in dealing with larger units of language such as morphemes. First, the performance
of dyslexic children in a series of morphological tasks was compared with the performance of children matched on reading-level
and chronological age. In all the tasks, the dyslexic group performed below the chronological age control group, suggesting
that morphological awareness cannot be developed entirely independently of reading experience and/or phonological skills.
Comparisons with the reading-age control group indicated that, while the dyslexic children were poorer in the morphemic segmentation
tasks, they performed normally for their reading level in the sentence completion tasks. Furthermore, they produced more derived
words in the production task. This suggests that phonological impairments prevent the explicit segmentation of affixes while
allowing the development of productive morphological knowledge. A second study compared dyslexic subgroups defined by their
degree of phonological impairment. Our results suggest that dyslexics develop a certain type of morphological knowledge, which
they use as a compensatory reading strategy. 相似文献

Previous research has repeatedly revealed evidence for morpho-orthographic priming effects in suffixed words. However, evidence for the morphological chunking of prefixed words is sparse and ambiguous. The goal of the present study was to directly contrast the processing of prefixed and suffixed pseudowords within the same experiment. We carried out a masked primed lexical decision experiment, in which the same target (AMOUR [LOVE]) was preceded by a prefixed (préamour [prelove]), a nonprefixed (brosamour [broslove]), a suffixed (amouresse [lovedom]), and a nonsuffixed (amourugne [lovedel]) prime. The results revealed significant priming across all four conditions. Moreover, priming was modulated by individual differences in reading proficiency. High-proficiency readers showed evidence for embedded stem priming effects, independent of whether stems occurred in combination with a real affix or a nonaffix. This finding is of relevance to recent morphological processing theories, suggesting that embedded stems represent salient activation units during the reading of complex pseudowords. 相似文献

We assessed the reading and reading-related skills (phonemic awareness and phonological short-term memory) of deaf children fitted with cochlear implants (CI), either exposed to cued speech early (before 2 years old) (CS+) or never (CS-). Their performance was compared to that of 2 hearing control groups, 1 matched for reading level (RL), and 1 matched for chronological age (CA). Phonemic awareness and phonological short-term memory were assessed respectively through a phonemic similarity judgment task and through a word span task measuring phonological similarity effects. To assess the use of sublexical and lexical reading procedures, children read pseudowords and irregular words aloud. Results showed that cued speech improved performance on both the phonemic awareness and the reading tasks but not on the phonological short-term memory task. In phonemic awareness and reading, CS+ children obtained accuracy and rapidity scores similar to CA controls, whereas CS- children obtained lower scores than hearing controls. Nevertheless, in phonological short-term memory task, the phonological similarity effect of both CI groups was similar. Overall, these results support the use of cued speech to improve phonemic awareness and reading skills in CI children. 相似文献

Retention of a brightness discrimination avoidance task by rats is impaired (Kamin effect) following a 1-h training-to-test interval (TTI), is enhanced after a 3-day TTI (reminiscence, or long-term spontaneous improvement), and is disrupted following a 21-day TTI (long-term forgetting). An exposure to the conditioned stimulus (CS), delivered 5 mm before a 1-h delayed retention test, not only compensated for the performance deficit that corresponds to the Kamin effect, but induced a large improvement in performance similar to that normally obtained after a 3-day TTI. It can be proposed that such cuing may act either by accelerating a natural memory-trace maturation process or by improving the retrievability of the memory trace. Since these possibilities lead to opposite predictions concerning the length of the facilitation induced by cuing, the effect of a pretest exposure to the CS on performance obtained during a 1-h delayed retention test was studied after several cuing-to-test intervals (0, 5, 10, or 20 min). The results, which indicate that cuing transiently enhanced subsequent retention performance, more convincingly support the retrieval hypothesis. The effects of pretest exposure to the CS (which occurred 5 min before testing) were also examined 10 min, 1 h, or 24 h after initial training. The results indicate that the facilitative effect of cuing obtained when retention performance was disrupted shortly after training (1-h TTI) was also obtained after a 24-h retention interval, in the absence of performance disruption. An interpretation of the facilitative effect of a pretest exposure to the CS is proposed, and implications concerning the memory trace are further discussed in relation to the multidimensional hypothesis. 相似文献

We bring different theories together to develop a theoretical framework that helps to understand how early warning messages about (new) dangerous drugs can influence the public's perception of substance use. We bring together the agenda setting theory, framing theory, dual processing theory, social learning theory, health belief model, theory of planned behavior, and cultivation theory in order to explain how warning messages diffused through the mass media can have an impact on the receivers' perceptions. Based on these insights we construct the Integrated Media Effect Framework (IMFE) that takes into account the role of cultural and structural contexts in the realm of early warning systems (EWS). Ultimately, this framework provides valuable guidelines for conceptualizing EWS and for developing applications by governments. 相似文献
