This study was aimed at clarifying relations between the way students learn and personal, contextual and performance variables. Students from seven different academic disciplines completed the Inventory of Learning Styles (ILS). Besides, data about their age, gender, academic discipline, prior education and exam performance were gathered. Regression and correlations analyses were used to analyse the data. The results showed that students learning patterns were indeed associated with personal and contextual factors such as academic discipline, prior education, age and gender, but that the different learning patterns had different sources. Second, students learning patterns proved to explain an important part of the variance in their academic performance. However, the results also revealed that exams as usually used in the first years of higher education hardly capitalise on students use of critical, analytical and concrete processing strategies. 相似文献

Video is often used in professional development courses to sensitize mathematics teachers to students’ thinking and issues of classroom interaction. This article presents an approach that incorporates students’ perspectives on mathematics classroom interactions into video-based professional development in order to enhance teachers’ reflection on diverse awareness of students concerning demands within mathematics classroom interactions. This approach is theoretically justified by the empirical research on equal participation in classroom interaction and practically elaborated by video material from Grade 5 students. Empirical snapshots from design experiments with teachers demonstrate that teachers’ sensitivity can be enhanced. 相似文献

Kim and Roth (this issue) purport to draw on the social-psychological theory of L. S. Vygotsky in order to investigate social relations in children’s argumentation in science topics. The authors argue that the argumentation framework offered by Stephen Toulmin is limited in addressing social relations. The authors thus criticize Toulmin’s Argument Pattern (TAP) as an analytical tool and propose to investigate the genesis of evidence-related practices (especially burden of proof) in second- and third-grade children by studying dialogical interactions. In this paper, I illustrate how Toulmin’s framework can contribute to (a) the study of “social relations”, and (b) provide an example utilizing a theoretical framework on social relations, namely Engeström’s Activity Theory framework, and (c) describe how we have used the Activity Theory along with TAP in order to understand the development of argumentation in the practices of science educators. Overall, I will argue that TAP is not inherently incapable of addressing social relational aspects of argumentation in science education but rather that science education researchers can transform theoretical tools such as Toulmin’s framework intended for other purposes for use in science education research. 相似文献

Knowledge of the equilibrium bed-concentration is vital to mathematical modeling of the river-bed deformation associated with
suspended load but previous investigations only dealt with the reference concentration of uniform sediment because of difficulties
in observation of the bed-concentration. This work is a first attempt to develop a theoretical formula for the equilibrium
bed-concentration of any fraction of nonuniform sediment defined at the bed-surface. The formula is based on a stochastic-mechanistic
model for the exchange of nonuniform sediment near the bed, and described as a function of incipient motion probability, non-ceasing
probability, pickup probability, and the ratio of the average single-step continuous motion time to static time. Comparison
of bed-concentration calculated from the proposed formula with the measured data showed satisfactory agreement, indicating
the present formula can be used for solving the differential equation goverming the motion of suspended load.

This study examined the interaction between college students attachment orientation and mentors relational style in the prediction of students behaviors and perceptions in academic mentoring and of their subsequent academic achievement. Ninety college students were administered the Adult Attachment Interview and their professors-mentors completed the Attachment Style Questionnaire. Students displayed more adaptive behaviors and perceptions in mentoring and earned higher grades when their attachment orientation was in contrast to their mentors relational style. Implications for the practice of academic mentoring in college are discussed. 相似文献

This study examined the time course of typing in prelingually and profoundly deaf as well as hearing individuals. Both groups
of participants performed a written picture naming task and a written pseudoword task. Keystroke timing measurements from
the written picture naming task revealed that the deaf as well as the hearing group were significantly delayed at syllable
boundaries compared to identical within-syllable letter combinations. As the deaf are impoverished with respect to phonology
based on spoken language experience, we postulate that syllabic segmentation is not crucially dependent on experience with
spoken language. Furthermore, delays at syllable boundaries were not affected by word frequency in both groups, in contrast
to the keys straddling a root morpheme boundary. Together with the finding that delays at syllable boundaries also occur in
pseudowords, the experiments provide strong evidence towards post-lexical syllabification processes. Our results support previous
findings which claim that (1) orthosyllables are autonomous and mode-specific entities, and (2) that the principles of syllabic
organisation apply post-lexically. 相似文献

Colloids play an important role in our modern lives. In this article, we briefly discuss various forces that are known to operate between colloidal particles and then take the reader through the discovery of a new, strong and long ranged force operating between hydrophobic particles/surfaces. Characteristics of the new force and some promising theories proposed in the literature to explain its origin are also discussed; the origin of the new force is not yet resolved, however. 相似文献

Ordinal, interval, and circadian mechanisms of solving a time-place task were tested. Rats searched for food twice in the morning and once in the afternoon (Group AB-C,n=5) or once in the morning and twice in the afternoon (Group A-BC,n=5) in a box with four food troughs. The location of the food depended on the time of day in a 12:12-h light:dark cycle. Acquisition was documented by foodsite inspections at the correct locations prior to food availability. On nonrewarded probes, the time of the middle search (B) was shifted late (for Group AB-C) or early (for Group A-BC). The rats visited Location B at chance, contrary to an ordinal mechanism. When the posttesting meal and light-dark transitions were omitted, the rats visited correct locations with impaired performance but at abovechance levels on nonrewarded probes. The results are consistent with interval and circadian representations of time. 相似文献
