When induction meets memory: evidence for gradual transition from similarity-based to category-based induction   总被引：3，自引：0，他引：3  

Fisher AV  Sloutsky VM 《Child development》2005,76(3):583-597

The ability to perform induction appears early; however, underlying mechanisms remain unclear. Some argue that early induction is category based, whereas others suggest that early induction is similarity based. Category- and similarity-based induction should result in different memory traces and thus in different memory accuracy. Performing induction resulted in low memory accuracy in adults and 11-year-olds, whereas 5-, and 7-year-olds were highly accurate (Experiment 1). After training to perform category-based induction, 5- and 7-year-olds exhibited patterns of accuracy similar to those of adults (Experiment 2). Furthermore, 7-year-olds, but not 5-year-olds, retained this training over time (Experiment 3). With novel categories, even adults performed similarity-based induction, exhibiting high memory accuracy (Experiment 4). These results suggest a gradual transition from similarity- to category-based induction with familiar categories.  相似文献   

Changeover contingencies and choice on concurrent schedules     

Leon R. Dreyfus  Dee Deporto-Callan  Sarah Anna Pesillo 《Learning & behavior》1993,21(3):203-213

Pigeons were trained on a multiple concurrent schedule with two components per session. In one component, changing schedules required the completion of a small fixed ratio on the switching key (a fixed-ratio changeover, or FRCO), and in the other component, changing schedules required only one switching response but engaged a changeover delay (COD) during which keypecks were not reinforced. Response ratios overmatched reinforcer ratios under the FRCO but undermatched under the COD. There was no difference in time allocation. In addition to these molar regularities in behavior, there were characteristic differences in performance at the molecular level. These local patterns of behavior, which can be explained within the context of contingencies created by the different changeover requirements, appear to underlie differences in performance at the molar level. Obtained molar differences in performance are not compatible with the assumption that there is a “general outcome” on concurrent schedules; and explaining these molar differences in performance in terms of the local contingencies of reinforcement is contrary to the assumption that behavior is allocated as a function of molar distributions of reinforcers.  相似文献   

Dyslexia in a second language?—a dynamic test of reading acquisition may provide a fair answer     

C Elbro  HT Daugaard  AS Gellert 《Annals of dyslexia》2012,62(3):172-185

Dyslexia is hard to diagnose in a second language. Poor performance on a test of reading may be caused by poor language proficiency in the second language or by limited schooling rather than by poor reading ability per se. This confound was supported in a study of 88 adult second language learners and 65 native language speakers. The incidence of dyslexia in the second language learners varied widely depending on the measure of reading. In order to reduce language and schooling confounds, a dynamic test of acquisition of basic decoding ability was developed. In the dynamic test, participants are taught three novel letters and to synthesise the letter sounds into new words. Results from the study indicated that the dynamic test provided results in accordance with the current IDA definition of dyslexia, while significantly reducing the influence second language vocabulary and amount of schooling. With the dynamic measure, the same cut-off point between dyslexic and non-dyslexic performance appeared valid in both native language speakers and second language learners.  相似文献   

Factors affecting bioscience students’ academic achievement   总被引：1，自引：0，他引：1  

Henna Rytk?nen  Anna Parpala  Sari Lindblom-Yl?nne  Viivi Virtanen  Liisa Postareff 《Instructional Science》2012,40(2):241-256

The examination of academic progression has become an essential tool for measuring the effectiveness of educational systems. Research concerning the relationship between student learning and how they progress in their studies, however remains scarce. The aim of this study is two-fold: Firstly, the study aims to analyse first-year bioscience students’ perceptions of their teaching–learning environment and their approaches to learning as well as the relationship of these to academic achievement as measured by students’ progression in studies and how they succeed. Secondly, the present study explores factors students feel either enhance or impede their studying as well as the relationship of those factors with their approaches to learning and academic achievement. The data consist of responses from 188 first-year students who began their studies in the fall 2007 and 2008. The data were collected in a Finnish context with a modified and shortened version of the Experiences in Teaching and Learning Questionnaire (ETLQ). The analyses were carried out using factor analysis, one-way ANOVA and structural equation modeling. According to the results, organised studying was related to both academic progression and study success. In addition, academic progression was positively related to peer support. Furthermore, most of the students found that problems in time management impeded their studies and that pre-set schedules enhanced them. Results indicate that social support and self-regulation skills are important for academic achievement.  相似文献   

Co-teaching as a context for teachers' professional learning and joint knowledge construction     

Anna Rytivaara  Ruth Kershner 《Teaching and Teacher Education》2012

The study examined two primary teachers' professional learning and joint knowledge construction in the context of co-teaching. The teachers narrated their learning as a collaborative process with serendipitous origins. Shared knowledge construction was crucial in the learning process, as was implementing the resulting new ideas in practice. It is concluded that experiences of co-teaching may support teachers in meeting their professional responsibilities effectively. Professional development programmes need to be sensitive to teachers' individual and collaborative learning experiences to be able better to support them in the natural context of those experiences in particular local and national contexts.  相似文献   

The Watch-and-Wait Task: On the reliability and validity of a new method of assessing self-control in preschool children     

Anna Neubauer  Caterina Gawrilow  Marcus Hasselhorn 《Learning and individual differences》2012,22(6):770-777

A preschooler's ability to delay gratification in the waiting task is predictive of several developmental outcomes, despite this task's relatively low reliability level. Success in this task depends on the use of distraction strategies. The new Watch-and-Wait Task (WWT) has been developed to enhance reliability and to investigate whether the waiting situation is equally predictive if distraction from the reward is inhibited. To prevent distraction in the WWT, children were instructed to watch an hourglass run out during the waiting period. In a reliability analysis (n = 31) the WWT showed acceptable retest reliability. In a second study (n = 61), the time preschoolers spent waiting in the WWT was associated with later academic achievement and behavioral problems diagnosed at the end of grade 1, even after controlling for intelligence, gender and age. Overall, the WWT proved to be a reliable instrument predictive of children's behavioral and academic development.  相似文献   

Experiences of instructors in online learning environments: Identifying and regulating emotions     

Kelley Regan  Anna Evmenova  Pam Baker  Marci Kinas Jerome  Vicky Spencer  Holly Lawson  Terry Werner 《The Internet and Higher Education》2012,15(3):204-212

In an effort to expand existing research on the barriers of instructors experience in online learning environments (OLEs), a qualitative study was conducted at a large mid-Atlantic university. Six instructors teaching in different OLE formats (e.g., asynchronous, hybrid, and synchronous via videoconferencing) participated in two focus groups in order to explore their emotional experiences and ways to regulate the emotions when teaching in OLEs. The overarching themes included emotions of feeling (a) restricted, (b) stressed, (c) devalued, (d) validated, and (e) rejuvenated. The article also provides practical strategies on how participating instructors attempted to manage the challenging emotions. A consensus among all participants is that continuous dialog in a community of practice about strategies to enhance OLEs is imperative.  相似文献

Growth or steady state? A bibliometric focus on international comparative higher education research     

Anna Kosmützky  Georg Krücken 《Higher Education》2014,67(4):457-472

The study combines a bibliometric approach with a content analysis of abstracts of articles to explore the patterns of international comparative higher education research in leading international journals. The overall data set covers 4,095 publications from the Web of Science for the period 1992–2012 and the amount of international comparative articles in this data set is analyzed utilizing a geographical coding. Contrary to a general proliferation of international and global trends in higher education, the results of the analysis most importantly reveal a relatively steady state of international comparative higher education research over the past 20 years. Further patterns examined show that international collaborative articles have a much higher share in international comparative research compared to non-comparative research, small-scale country clusters are preferred for comparison and there is a dense network of comparative clusters between Europe and the US. Finally, rationales for these patterns are discussed, as well as potential implications.  相似文献
