The gross anatomy dissection course is a cost‐intensive piece of undergraduate medical education that students and professionals alike describe as very important within the overall medical curriculum. We sought to understand more explicitly students' valuation of gross anatomy as an “important” course and so developed a quantitative longitudinal questionnaire. Medical students (n = 124) enrolled in the winter term 2006/2007 gross anatomy course at the Ulm University Faculty of Medicine were surveyed anonymously prior to, in the middle of, and at the end of the dissection course. Subgroups of students expressing rising or falling opinions of course value were identified and correlated with student opinions about the course's ability to convey professional competencies. Five‐point Likert scales were used for each survey item, which included such standardized instruments as the NeoFFI, BSI, and FBM. The study confirmed that medical students believe dissection to be valuable. Students indicated that participation in the course facilitated acquisition of anatomy knowledge as well as skills related to teamwork, coping with stress, and, to a lesser extent, time management. Students also noted that they developed less empathy than expected beforehand. Significant subgroup differences were observed relative to the competencies of teamwork, stress coping strategies, and empathy, as well as in students' stress levels associated with having to take a dissection course. Our study builds on previous work that has shown dissection courses help students develop professional competencies. The increase in professionalism might be a reason for the generally high value students place on the gross anatomy dissection course, Anat Sci Educ 3:3–11, 2010. © 2010 American Association of Anatomists.  相似文献

Phonological recoding,orthographic decoding,and comprehension skills during reading acquisition     

Julia Knoepke M.A.  Prof. Dr. Tobias Richter  Dr. Maj-Britt Isberner  Prof. Dr. Johannes Naumann PhD  Yvonne Neeb 《Zeitschrift für Erziehungswissenschaft》2014,17(3):447-471

To become skillful readers, children have to acquire the ability to translate printed words letter by letter into phonemic representations (phonological recoding) and the ability to recognize the written word forms holistically (orthographical decoding). Whereas phonological recoding is the key for learning to read and useful for recognizing unknown or low-frequent words, orthographical decoding is often more efficient and takes less time, thus facilitating reading processes on the sentence and text level. Several studies with English-speaking children provided evidence for the relevance of the two routes but the question whether and to what extent both word recognition skills contribute to reading comprehension in young German readers requires further clarification. Based on data from a cross-sectional study with German primary school children we investigated whether and to what extent both types of word recognition skills are associated with sentence (N = 666) and text comprehension skills (N = 149) and how these relationships develop from Grade 2 to 4. The results indicate that both phonological recoding skills and orthographical decoding skills are important for reading comprehension skills. Their relative weight does not change across grade levels.  相似文献   

Robuste Indizes für Projection Pursuit     

Tobias Rohatsch  Gerhard P?ppel und Heinrich Werner 《Informatik - Forschung und Entwicklung》2002,17(2):53-59

Zusammenfassung.   Die moderne und hoch komplexe Fertigung, z.B. in der Halbleiterindustrie, erfordert für die dabei anfallenden Messdaten der Anlagen- bzw. Prozessparameter multivariate Analysemethoden. Eine dieser m?glichen Analysemethoden ist Projection Pursuit (PP). Dieses Verfahren ist durch geschickte Wahl des so genannten Projektionsindex in der Lage, verschiedenste Datencharakteristika zu detektieren und diese auf anschauliche Weise zu visualisieren. Bei den Projektionsindizes handelt es sich um Funktionen, die eine Projektion auf unterschiedliche Merkmale hin bewerten und dabei jeder Projektion einen Funktionswert zuweisen. Dieser Funktionswert spiegelt die Aussagekraft der Projektion (in Abh?ngigkeit vom verwendeten Index) wider. Die Auswahl bzw. der Aufbau dieser Indizes ist hierbei von entscheidender Bedeutung. Alle hier vorgestellten Indizes zeichnen sich vor allem durch ihren robusten Charakter gegenüber durch Ausrei?er kontaminierte Daten, wie sie in realen Datenszenarien vorkommen, aus. Die durch Anwendung dieser Indizes gewonnenen Einblicke in die komplexe Struktur der Daten erm?glichen es, hochdimensionale Parameterabweichungen und komplexe Zusammenh?nge innerhalb der Daten zu finden.

The use of source-related strategies in evaluating multiple psychology texts: a student–scientist comparison     

Sarah von der Mühlen  Tobias Richter  Sebastian Schmid  Elisabeth Marie Schmidt  Kirsten Berthold 《Reading and writing》2016,29(8):1677-1698

Multiple text comprehension can greatly benefit from paying attention to sources and from using this information for evaluating text information. Previous research based on texts from the domain of history suggests that source-related strategies are acquired as part of the discipline expertise as opposed to the spontaneous use of these strategies by students just entering a field. In the present study, we compared the performance of students and scientists in the domain of psychology with regard to (a) their knowledge of publication types, (b) relevant source characteristics, (c) their use of sources for evaluating the credibility of multiple texts, and (d) their ability to judge the plausibility of argumentative statements in psychological texts. Participants worked on a battery of newly developed computerised tests with a think-aloud instruction to uncover strategies that scientists and students used when reading a text. Results showed that scientists scored higher in all of the assessed abilities and that these abilities were positively correlated with each other. Importantly, the superior performance of scientists in evaluating the credibility of multiple texts was mediated by their use of source information. Implications are discussed in terms of discipline expertise.  相似文献   

Analyzing Different Types of Moderated Method Effects in Confirmatory Factor Models for Structurally Different Methods     

Tobias Koch  Augustin Kelava  Michael Eid 《Structural equation modeling》2018,25(2):179-200

An extension of two confirmatory factor models for multitrait-multimethod measurement designs with structurally different methods to the analysis of latent interaction effects is presented: the nonlinear latent difference (NL-LD) model and the nonlinear correlated trait–correlated method-minus-one (NL-CTC[M – 1]) model. Both models are compared with regard to (a) the psychometric definition of the latent variables, (b) the capabilities of explaining latent method effects, and (c) the analysis of latent interaction effects. Using the latent moderated structural equation approach, we show how moderated method effects can be examined in the NL-CTC(M – 1) model. This fine-grained analysis of method effects is not feasible using the classical NL-LD model. We propose an extended version of the NL-LD model, which recovers the results of the NL-CTC(M – 1) model. The different versions of the nonlinear multimethod models are illustrated using real data from a multirater study. Finally, the advantages and challenges of incorporating latent interaction effects in complex CFA–MTMM models are discussed.  相似文献   

Take home tests: An experimental study     

Larry J. Weber  Janice K. McBee  Jean E. Krebs 《Research in higher education》1983,18(4):473-483

The take home test was compared with the conventional closed and open book tests at the college level. It was found that scores on knowledge items were significantly higher with the take home test, and that additional time spent looking up answers was important. An additional factor was the level of anxiety, perceived by students to be less with the take home test. Rampant cheating does not appear to be a problem with take home tests.  相似文献   

Connecting Classroom Science with Everyday Life: Teachers’ Attempts and Students’ Insights     

Tobias Irish  Nam-Hwa Kang 《International Journal of Science and Mathematics Education》2018,16(7):1227-1245

This multiple case study examines how teachers request students’ use of their content knowledge and conceptual understandings from out-of-school experiences while reasoning about science concepts and the ways in which students perceive and respond to these requests. Three middle school teachers and a total of 57 middle school students participated in this study. The data collection involved classroom observations and multiple interviews with each of the teachers individually and with small groups of students. The findings indicate that the students appreciate the usefulness of making relevant connections between their in-school and out-of-school learning, but seldom do so during science lessons. We also found that teachers’ attempts to facilitate these types of connections during classroom discourse events involved the use of analogies, examples, or questions. Finally, the findings also indicate that students often recognize teachers’ requests but seldom relate to these requests in the way the teacher intends.  相似文献   

Do Belonging and Social Exclusion at School Affect Structural Brain Development During Adolescence?

Students’ sense of belonging presents an essential resource for academic and health outcomes, whereas social exclusion at school negatively impacts students’ well-being and academic performance. Aiming to understand how feelings of school-related belonging and exclusion shape the structural brain development, this study applied longitudinal questionnaire-based data and MRI data from 71 adolescent students (37 females, M_age at t1 = 15.0; t2 = 16.1 years). All were white participants from Germany. Voxel-based morphometry revealed only an association of social exclusion (and not of belonging) and gray matter volume in the left anterior insula: From t1 to t2, there was less gray matter decrease, the more social exclusion students perceived. School-related social exclusion and disturbed neurodevelopment are thus significantly associated.  相似文献
