Using meta-reflection to improve learning and throughput: redesigning assessment procedures in a political science course on power     

Linus Hagström  Max Scheja 《Assessment & Evaluation in Higher Education》2014,39(2):242-252

The aim of this article is to contribute to the discussion on how examinations can be designed to enhance students’ learning and increase throughput in terms of the number of students who sit, and pass, the course examination. The context of the study is a basic level political science course on power analysis, which initially suffered from low throughput. The contribution of the article is to demonstrate that no other changes to the course than the introduction of an element of meta-reflection in the take-home examination – a so-called ‘reflection exercise’ – helped increase throughput by 70–80%. The aggregated performance of the students was thus significantly enhanced after they were explicitly encouraged to meta-reflect on problems posed in the take-home examination, and on different strategies for tackling these problems. The introduction of another meta-reflection exercise in the mandatory seminars did not further increase throughput, but made a qualitative difference in terms of the positive feedback that students received on their work.  相似文献   

PBL and CDIO: complementary models for engineering education development     

Kristina Edström  Anette Kolmos 《European Journal of Engineering Education》2014,39(5):539-555

This paper compares two models for reforming engineering education, problem/project-based learning (PBL), and conceive–design–implement–operate (CDIO), identifying and explaining similarities and differences. PBL and CDIO are defined and contrasted in terms of their history, community, definitions, curriculum design, relation to disciplines, engineering projects, and change strategy. The structured comparison is intended as an introduction for learning about any of these models. It also invites reflection to support the understanding and evolution of PBL and CDIO, and indicates specifically what the communities can learn from each other. It is noted that while the two approaches share many underlying values, they only partially overlap as strategies for educational reform. The conclusions are that practitioners have much to learn from each other's experiences through a dialogue between the communities, and that PBL and CDIO can play compatible and mutually reinforcing roles, and thus can be fruitfully combined to reform engineering education.  相似文献   

Teachers and Students’ Conceptions of Computer-Based Models in the Context of High School Chemistry: Elicitations at the Pre-intervention Stage     

Noemi Waight  Kristina Gillmeister 《Research in Science Education》2014,44(2):335-361

This study examined teachers’ and students’ initial conceptions of computer-based models—Flash and NetLogo models—and documented how teachers and students reconciled notions of multiple representations featuring macroscopic, submicroscopic and symbolic representations prior to actual intervention in eight high school chemistry classrooms. Individual in-depth interviews were conducted with 32 students and 6 teachers. Findings revealed an interplay of complex factors that functioned as opportunities and obstacles in the implementation of technologies in science classrooms. Students revealed preferences for the Flash models as opposed to the open-ended NetLogo models. Altogether, due to lack of content and modeling background knowledge, students experienced difficulties articulating coherent and blended understandings of multiple representations. Concurrently, while the aesthetic and interactive features of the models were of great value, they did not sustain students’ initial curiosity and opportunities to improve understandings about chemistry phenomena. Most teachers recognized direct alignment of the Flash model with their existing curriculum; however, the benefits were relegated to existing procedural and passive classroom practices. The findings have implications for pedagogical approaches that address the implementation of computer-based models, function of models, models as multiple representations and the role of background knowledge and cognitive load, and the role of teacher vision and classroom practices.  相似文献   

Does learning in clinical context in anatomical sciences improve examination results,learning motivation,or learning orientation?          下载免费PDF全文

Anja Böckers  Christian Mayer  Tobias Maria Böckers 《Anatomical sciences education》2014,7(1):3-11

The preclinical compulsory elective course “Ready for the Operating Room (OR)!?” [in German]: “Fit für den OP (FOP)”] was implemented for students in their second year, who were simultaneously enrolled in the gross anatomy course. The objective of the study was to determine whether the direct practical application of anatomical knowledge within the surgical context of the course led to any improvement in learning motivation, learning orientation, and ultimately examination results in the gross anatomy course, as compared with a control group. Within the scope of five teaching sessions, the students learned surgical hand disinfection, suturing techniques, and the identification of commonly used surgical instruments. In addition, the students attended five surgical demonstrations performed by surgical colleagues on cadavers. Successful learning of these basic skills was then assessed based on an Objectively Structured Practical Examination. Learning motivation and learning orientation in both subgroups was determined using the SELLMO‐ST motivation test and the Approaches and Study Skills Inventory test. While a significant increase in work avoidance was identified in the control group, this was not the case for FOP participants. Similarly, an increase in the “deep approach” to learning, as well as a decrease in the “surface approach,” was able to be documented among the FOP participants following completion of the course. The results suggest that students enrolled in the gross anatomy course, who were simultaneously provided with the opportunity to learn in clinical context, were more likely to be successful at maintaining learning motivation and learning orientation required for the learning process, than students who attended the gross anatomy course alone.

Different habitus: different strategies in teaching physics? Relationships between teachers’ social,economic and cultural capital and strategies in teaching physics in upper secondary school     

Susanne Engström  Carina Carlhed 《Cultural Studies of Science Education》2014,9(3):699-728

With environmental awareness in the societies of today, political steering documents emphasize that all education should include sustainable development. But it seems to be others competing ideals for teaching physics, or why do the physics teachers teach as they do? Physics teachers in secondary school in Sweden have generally, been focused on facts and a strong link with scientific theories and concepts. In general, the curriculum sway the teaching, a standard text book in physics is used, the teaching is organized according to the book and the teacher deals with and demonstrates typical tasks on the whiteboard and group work is common for special issues related to tasks from the textbook or elaborating. The aim with this study is to analyze why physics teachers in upper secondary school choose to teach energy as they do. Data emerging from a questionnaire focused on indicators of the teachers’ cultural and economic assets, or capital, according to the work of Pierre Bourdieu’s sociology. Especially his concept on life styles and habitus provide a tool for analysis. We focus on physics teachers’ positions in the social space, dispositions and standpoints towards the ideal way to teach physics in upper secondary school (n = 268). Our response rate is 29 % and due to the low response rate a non response bias analysis was made. In our analysis we primarily sought for groups, with a cluster analysis based on the teaching practice, revealed common features for both what and how they teach and three different teaching types emerged. Then we reconstructed the group habitus of the teachers by analyzing dispositions and standpoints and related those to the specific polarization of sacred values, that is struggles about the natural order (doxa) in the social space of science education, which is a part of and has boundaries to dominating fields like the natural sciences and the political fields (curriculum etc.). Three teacher-groups’ habituses are described and analyzed; (1) The Manager of the Traditional, (2) The Challenger for Technology and (3) The Challenger for Citizenship. By constructing the habitus of the teachers in the different groups we can explain why teachers teach as they do and thereby make a contribution to both science education research and to teaching training, whereas reflective approach which also includes the individual dispositions and representations are paramount. In our paper we elaborate the grounds and implications of these findings further.  相似文献   

The impact of reading material’s lexical accessibility on text fading effects in children’s reading performance     

Telse Nagler  Jan Lonnemann  Janosch Linkersdörfer  Marcus Hasselhorn  Sven Lindberg 《Reading and writing》2014,27(5):841-853

The acceleration phenomenon (AP) is defined by improvements in reading speed and reading comprehension, induced by an artificial text fading procedure corresponding to the previously determined fastest individual reading rate. Recent results, however, indicated that fading that is slower than the self-paced reading rate can produce comparable reading enhancements. As reading performance can be strongly influenced by the reading material, this study aimed at investigating to which extent reading enhancements induced by text fading depend on the reading material’s characteristics. We confronted 39 German third graders with a previously utilized text fading procedure, which was slower than their self-paced reading rate. Included text varied regarding to the lexical accessibility (LA), representing how well information can be accessed from the mental lexicon. Children’s reading rates increased statistically significant due to text fading for all LA levels. However, reading comprehension was sensitive to the text material’s characteristics: Reading comprehension enhancements were observable for easily accessible reading material, but not for material with intermediate or difficult levels of LA. Material that was difficult to retrieve from the mental lexicon even resulted in reduced reading comprehension in the fading condition. Possible influences on immediate lexical access, the impact of working memory capacity and implications for future AP research are discussed.  相似文献   

Does sensitivity to orthographic regularities influence reading and spelling acquisition? A 1-year prospective study     

Josefine Rothe  Gerd Schulte-Körne  Elena Ise 《Reading and writing》2014,27(7):1141-1161

Recent studies focused on the influence of orthographic processing on reading and spelling performance. It was found that orthographic processing is an independent predictor of reading and spelling performance in different languages and children of different ages. This study investigated sensitivity to orthographic regularities in German-speaking children (N = 31) prior and during formal reading and spelling instruction. In addition, the relationship between sensitivity to orthographic regularities and reading and spelling performance was explored. Two aspects of children’s sensitivity to orthographic regularities (sensitivity to frequent double consonants and sensitivity to legal positions of double consonants) were measured with a nonword forced choice task. The results show that sensitivity to orthographic regularities improved significantly from kindergarten to first grade. Moreover, children’s sensitivity to orthographic regularities at the end of first grade accounted for a significant amount of unique variance in their reading and spelling performance. These results suggest that orthographic sensitivity on a sublexical level is important for the development of reading and spelling skills.  相似文献   

The Nature and Role of Thought Experiments in Solving Conceptual Physics Problems     

Şule Dönertaş Kösem  Ömer Faruk Özdemir 《Science & Education》2014,23(4):865-895

This study describes the possible variations of thought experiments in terms of their nature, purpose, and reasoning resources adopted during the solution of conceptual physics problems. A phenomenographic research approach was adopted for this study. Three groups of participants with varying levels of physics knowledge—low, medium, and high level—were selected in order to capture potential variations. Five participants were selected within each level group and the study was conducted with fifteen participants in total. Think aloud and retrospective questioning strategies were used throughout the individually conducted problem solving sessions to capture variations in the participants’ thinking processes. The analysis of the data showed that thought experiments were actively used cognitive tools by participants from all there levels while working on the problems. Four different thought experiment structures were observed and categorized as limiting case, extreme case, simple case, and familiar case. It was also observed that participants conducted thought experiments for different purposes such as prediction, proof, and explanation. The reasoning resources behind the thought experiment processes were classified in terms of observed facts, intuitive principles, and scientific concepts. The results of the analysis suggested that thought experiments used as a creative reasoning tool for scientists can also be a productive tool for students. It was argued that instructional practices enriched with thought experiments and related practices not only reveal hidden elements of students’ reasoning but also provide students opportunities to advance their inquiry skills through thought experimentation processes.  相似文献   

What is not working in working memory of children with literacy disorders? Evidence from a three-year-longitudinal study     

Anne Fischbach  Tanja Könen  Chantal S. Rietz  Marcus Hasselhorn 《Reading and writing》2014,27(2):267-286

The goals of this study were to explore the deficits in working memory associated with literacy disorders (i.e. developmental disorders of reading and/or spelling) and the developmental trajectories of these working memory deficits. The performance of 28 children with literacy disorders was compared to a non-disabled control group with the same group size at five bi-annual times of measurement in a three-year-longitudinal study beginning at the end of primary school (9.5 years of age). Storage capacity and central-executive working memory were assessed in phonological and visual-spatial modalities, the latter under static and dynamic conditions. Overall, children with literacy disorders were outperformed by their typical developing peers in all phonological and in dynamic visual-spatial storage and central-executive tasks except for the static visual-spatial storage task. Results at single times of measurement revealed that the most consistent deficit was found in the storage capacity of the phonological loop. An additional central-executive impairment is supported by low backward spans. The causes for output deficits in dynamic visual-spatial tasks and good performance under static visual-spatial condition are discussed.  相似文献
