Retrieval-based learning in special education     

Tobias Tempel  Sebastian Sollich 《Journal of Research in Special Educational Needs》2023,23(3):244-250

Retrieval-based learning has been investigated in various populations. The present study examined retrieval-based learning in a sample of students at a special-needs school with educational tracks for learning and mental development. In addition, a comparison group of students at a regular school was examined. Learning conditions were manipulated within participants. In a first session, participants either received restudy cycles only, or they received alternating test and restudy cycles. A second session then comprised the opposite form of practice. In both sessions, a final test assessed memory after a short distractor phase. This procedure was the same in two experiments but with different kinds of item material. For both kinds (images and image-word pairs), a testing effect occurred, that is higher recall of tested items. These results show that lower cognitive ability or lack of experience with regularly being tested in school do not prevent students from benefiting from retrieval-based learning.  相似文献

The effects of knowledge management on innovative success – An empirical analysis of German firms     

Uwe Cantner  Kristin Joel  Tobias Schmidt 《Research Policy》2011,40(10):1453-1462

The aim of this paper is to analyse the effects of knowledge management on the innovation success of firms in Germany. We look at innovative firms in the period from 2000 to 2002 taken from the Mannheim Innovation Panel and estimate the effect of collaborative measures of knowledge management on the immediate economic success of different types of innovations. The results of our matching analysis reveal that firms which apply knowledge management perform better in terms of higher-than-average shares of turnover with innovative products compared to their twins. We do not find a significant effect of knowledge management on the share of cost reductions with process innovation.  相似文献   

Cognitive load in percentage change problems: unitary,pictorial, and equation approaches to instruction     

Bing Hiong Ngu  Alexander Seeshing Yeung  Stephen Tobias 《Instructional Science》2014,42(5):685-713

Eighth grade students in Australia (N = 60) participated in an experiment on learning how to solve percentage change problems in a regular classroom in three conditions: unitary, pictorial, and equation approaches. The procedure involved a pre-test, an acquisition phase, and a post-test. The main goal was to test the relative merits of the three approaches from a cognitive load perspective. Experimental results indicated superior performance of the equation approach over the unitary or pictorial approach especially for the complex tasks. The unitary approach required students not only to process the interaction between numerous elements within and across solution steps, but also to search for critical information, thus imposing high cognitive load. The pictorial approach did not provide a consistent approach to tackling various percentage change problems. Coupled with the need to coordinate multiple elements within and across solution steps, and the need to search for relevant information in the diagram, this approach imposed high cognitive load. By treating the prior knowledge of percentage quantity as a single unit, the equation approach required students to process two elements only. Empirical evidence and theoretical support favor the equation approach as an instructional method for learning how to solve percentage change problems for eighth graders.  相似文献   

Fostering multiple text comprehension: How metacognitive strategies and motivation moderate the text-belief consistency effect     

Johanna Maier  Tobias Richter 《Metacognition and Learning》2014,9(1):51-74

Learners often have difficulties comprehending multiple texts about controversial scientific issues. In particular, learners with strong prior beliefs tend to construct a one-sided mental representation that is biased towards belief-consistent information (text-belief consistency effect). In the present study we examined the effectiveness of information of three metacognitive strategies tailored to strengthen the comprehension of belief-inconsistent information during multiple text comprehension. According to theories of self-regulated learning, knowledge about relevant metacognitive strategies improves comprehension only when learners are also motivated to use these strategies. These hypotheses were investigated in an experiment in which 85 participants read one belief-consistent and one belief-inconsistent text about a controversial scientific issue. Participants either received information about three metacognitive strategies or no additional information. In addition, participants’ motivation was manipulated by providing them with either negative or positive performance feedback or no feedback. As predicted, a text-belief consistency effect was found, which was eliminated by strengthening the situation model for the belief-inconsistent text only when learners received information about relevant metacognitive strategies and were motivated to use these strategies after positive performance feedback.  相似文献

Specificity aboutness in XML retrieval     

Tobias Blanke  Mounia Lalmas 《Information Retrieval》2011,14(1):68-88

This paper presents a theoretical methodology to evaluate XML retrieval systems and their filters. Theoretical evaluation is concerned with the formal investigation of qualitative properties of retrieval models. XML retrieval deals with retrieving those document components that specifically answer a query, and filters are a method of delivering the most focussed answers. Our theoretical evaluation critically analyzes how filters achieve this.  相似文献   

On File Sharing With Indirect Network Effects Between Concert Ticket Sales and Music Recordings     

Ralf Dewenter  Justus Haucap  Tobias Wenzel 《Journal of Media Economics》2013,26(3):168-178

This article analyzes the interdependency between the market for music recordings on the one side and the market for concert tickets on the other side, assuming that there are positive indirect network effects both from the record market to ticket sales for live performances and vice versa. In a model with two interrelated Hotelling lines, prices in both markets are corrected downward when compared to the standard Hotelling model. In the integrated business model, file sharing has an ambiguous effect on firms' profitability. As file sharing can indirectly increase demand for live performances, overall profits can either increase or decrease, depending on the strength of indirect network effects. Finally, file sharing may induce firms to switch from the traditional business model with two separate firms to an integrated business model where one agency markets both records and concerts (so-called 360° deals).  相似文献   

How accurate are teacher and parent judgements of lower secondary school children’s test anxiety?     

Constance Karing  Tobias Dörfler  Cordula Artelt 《教育心理学》2015,35(8):909-925

This study examined teacher and mother judgement accuracy of children’s worries and emotionality in the school subjects of German and mathematics. The participants were 59 German language and 58 mathematics teachers, 572 mothers and their children at the end of Grade 6. The analyses for the total sample revealed weak-to-moderate correlations between adult’s and children’s perception of test anxiety. Moreover, we found that teachers overestimated children’s emotionality as well as children’s worry, whereas mothers underestimated children’s worry and overestimated children’s emotionality in both subjects. However, when looking at the highly test-anxious children, we found quite low correlations and an underestimation of children’s worry and emotionality in both school subjects. Thus, it seems important to provide teachers and parents with information about test anxiety and possibly training to improve their judgement accuracy because of moderating effects of test anxiety on achievement.  相似文献
