The paper draws on the Vygotskyan view of instruction, advocating the support of learners within their individual Zones of Proximal Development. It describes an instructional design developed iteratively—gradually building in scaffolding techniques to support the use of the procedural facilitation of text evaluation during revision—and the open-ended management of its provision to students, so that they could fade it out themselves.The study took place in a writing class for students at basic writing levels. The present, post hoc analysis is concerned with individual differences among three members of the class identified as weak, intermediate and more advanced novices while learning to revise within that program. 相似文献

Gender-related differences in reasoning skills and learning interests of junior high school students
Michal Shemesh 《科学教学研究杂志》1990,27(1):27-34
The purpose of this study was to investigate gender-related differences in the relationship between the development of formal reasoning skills and learning interests during the early adolescent stage. For this purpose, 249 students, from seventh to ninth grade, were assessed for their level of mastery of formal reasoning skills by a test based on videotaped simple experiments. Learning interests were assessed by a written response to an open question. Results showed that adolescent boys develop patterns of formal reasoning before their girl classmates. In addition, boys tend to prefer science and technology subjects, while girls tend to prefer language, social studies, and humanities. Analysis of interactions showed that boys' tendency toward science and technology is positively correlated to their age and development of formal reasoning, while girls' tendency to the above subjects is positively related to their development of formal reasoning capacity, but inversely related to their age. Possible explanations to the above-described findings and suggestions for instructional modes that may increase girls' interest in science and technology are discussed. 相似文献

This study examines ways of approaching deductive reasoning of people involved in mathematics education and/or logic. The
data source includes 21 individual semi-structured interviews. The data analysis reveals two different approaches. One approach
refers to deductive reasoning as a systematic step-by-step manner for solving problems, both in mathematics and in other domains.
The other approach emphasizes formal logic as the essence of the deductive inference, distinguishing between mathematics and
other domains in the usability of deductive reasoning. The findings are interpreted in light of theory and practice.

In light of recent reform recommendations, teachers are expected to turn proofs and proving into an ongoing component of their
classroom practice. Two questions emerging from this requirement are: Is the mathematical knowledge of high school teachers
sufficient to prove various kinds of statements? Does teachers’ knowledge allow them to determine the validity of an argument
made by their students? The results of this study, in which 50 secondary school teachers participated, point to a positive
answer to the first question in the framework of elementary number theory (ENT). However, the picture is more complex with
respect to the second one. Results indicated that some teachers may over-value the generality of symbolic mode of representation
and under-value the generality of verbal ones. Possibly, the verbal representation of an argument is less transparent and
more difficult to understand. 相似文献

Subtypes of reading disability in a shallow orthography: a double dissociation between accuracy-disabled and rate-disabled readers of Hebrew 总被引:1,自引:0,他引:1
Whereas most English language sub-typing schemes for dyslexia (e.g., Castles & Coltheart, 1993) have focused on reading accuracy for words varying in regularity, such an approach may have limited utility for reading
disability sub-typing beyond English in which fluency rather than accuracy is the key discriminator of developmental and individual
differences in reading ability. The present study investigated the viability of an accuracy/fluency-based typology in a regular
orthography, pointed Hebrew. We sought evidence of true or “hard” accuracy/rate subtypes in the strict (double dissociation)
sense of selective impairment on only one dimension in the presence of normal levels of performance on the other dimension. In a nationally representative sample of fourth graders, we were able to identify
a specific accuracy-disabled sub-group as well as an equally specific rate-disabled subgroup. Validating this subdivision,
we show that the nature of reading performance in these subgroups and their converging cognitive/linguistic profiles are unique
and distinctive on variables other than the measures used to define them. While the rate-specific disability appeared to reflect
a general deficit in speed of processing affecting reading rate, and rapid automatized naming of print-related material, the
accuracy-only disability subgroup displayed selective deficits in phonological awareness and morphological knowledge. Biosocial,
demographic, and instructional factors, furthermore, did not explain the sub-group differences. It appears that both these
subtypes are equally prevalent each counting close to 10% of the population. 相似文献

In this paper, we propose a dialogue-based navigation system for narrow areas (e.g., buildings, etc.). In particular, we develop Campus Navigation Partner System (CNPS), intended for the use by freshmen (first-year students) who are likely to get lost in the new environment on the university campus (with the campus of Kitami Institute of Technology set as the experimental environment). The CNPS operates on a smartphone and has the functions of facility navigation and indoor information presentation. Indoor environment navigation is typically a problematic task because GNSS (Global Navigation Satellite System) signals cannot be received with sufficient accuracy within concrete walls. Therefore, we utilized natural language dialogue as a navigation method that guides the users within the facility using navigation messages and images. To investigate the effectiveness of the constructed system, we conducted practical experiments with freshmen and senior students of the university and evaluated the performance of the navigation functionality. Moreover, we investigated the general impressions of the system which we evaluated separately with both freshmen and senior students to clarify the differences in evaluation viewpoints between freshmen and users experienced in the campus environment (graduate students, etc.). 相似文献

ABSTRACT Adults with learning disabilities (LD) constitute one of the fastest growing populations of students attending institutions of higher education. Faculty members play an important role in the adjustment and success of these students. The current study investigated the perceptions towards LD of faculty members at a public university in Israel. Specifically, the study examined the level of contact, attitudes, knowledge, and training of faculty members with respect to students with LD. The results demonstrated that faculty members overall had a significant amount of contact with and held positive attitudes towards students with LD. However, it appeared that faculty members would benefit from information regarding the current definition of LD, related legislation about LD and other disabilities, and training and support services for LD. Implications for practice and further research are discussed. 相似文献

Pollutants and their potential degradation of paintings have been measured for the first time in microclimate frames (mc-frames), which are used to protect paintings. The pollutants that were measured include both inorganic pollutants, which originate mainly from external sources, and organic pollutants from mainly internal sources. Those originating from the outdoors enter rooms and subsequently mc-frames at a rate depending on the ventilation rates (air exchange rates) of the mc-frames. The concentration of gaseous pollutants emitted within the mc-frames will depend on net emission rates of the materials used to make the mc-frames, their design, and their ventilation rates. In the EU PROPAINT project measurements of gaseous air pollutants and climatic conditions were performed at various locations both inside and outside different state-of-the-art mc-frames. Diffusive passive pollution gas samplers were used together with different types of dosimeters. Results show that the dosimeters respond to either the photo-oxidizing conditions or the level of volatile organic acids in the environments both in the museums and within the mc-frames. Two dosimeters, the Early Warning Organic (EWO) made from a synthetic polymer and the Resin Mastic coated Piezo electric Quartz Crystals (RM-PQC) respond to photo-oxidation and showed higher values outside than inside the mc-frames. Two other dosimeters, the Glass Slide Dosimeter (GSD) and the Lead coated Piezo electric Quartz Crystals (L-PQC) respond to volatile organic acids and yielded higher values inside than outside the mc-frames. This study emphasizes the need for further work to determine environmental damage functions for paintings, in particular for the effects of organic acids. Such information is essential for the evaluation of the protective effects of mc-frames for paintings. The use of mc-frames is increasing and it is very important to know that this protective measure does not introduce new risks. 相似文献
