Why and how mathematicians read proofs: an exploratory study     

Keith Weber  Juan Pablo Mejia-Ramos 《Educational Studies in Mathematics》2011,76(3):329-344

In this paper, we report a study in which nine research mathematicians were interviewed with regard to the goals guiding their reading of published proofs and the type of reasoning they use to reach these goals. Using the data from this study as well as data from a separate study (Weber, Journal for Research in Mathematics Education 39:431–459, 2008) and the philosophical literature on mathematical proof, we identify three general strategies that mathematicians employ when reading proofs: appealing to the authority of other mathematicians who read the proof, line-by-line reading, and modular reading. We argue that non-deductive reasoning plays an important role in each of these three strategies.  相似文献   

Teacher behavior, student interest and affective learning: putting theory to practice     

Keith Weber  Matthew Martin  Brian Patterson 《Journal of Applied Communication Research》2001,29(1):71-90

Students of Project Adapt (PA), an instructional program for at-risk middle school students in Brooklyn NY, have displayed startling improvement on cognitive outcome measures. Teacher given grades and standardized tests illuminate the progress students have made since entering the program. The current investigation attempts to analyze PA on students' affective responses in a pre/post-test experimental design. Upon entering PA, students completed measures of interest, affect, and their previous teachers' behavior (pre). These ratings were then compared to end of year ratings on the same instruments (post). Results indicate students' perceive PA teachers utilizing different behaviors than their previous teachers. Additionally, student affect and interest increased significantly. Results of this study have implications for both instructional researchers and educational practitioners.  相似文献   

Describing microforms and the marc formats     

Lisa B. Weber 《Archival Science》1987,1(2):9-13

Conclusion It is easy to get bogged down in the complexities of this topic. What is most important to keep in mind, (and what we tell the SAA MARC-AMC workshop participants) is to create a catalog record that expresses to the user what you want it to. However, this is often easier said than done.  相似文献

Cinematic Rendering in Anatomy: A Crossover Study Comparing a Novel 3D Reconstruction Technique to Conventional Computed Tomography     

Johannes S. Binder  Michael Scholz  Stephan Ellmann  Michael Uder  Robert Grützmann  Georg F. Weber  Christian Krautz 《Anatomical sciences education》2021,14(1):22-31

Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two-period crossover study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and comprehension of anatomy. Sixteen students were randomized into two assessment sequences. During each assessment period, participants had to answer 15 anatomy-related questions that were divided into three categories: parenchymal, musculoskeletal, and vascular anatomy. After a washout period of 14 days, assessments were crossed over to the respective second reconstruction technique. The mean interperiod differences for the time to answer differed significantly between the CR–CT sequence (−204.21 ± 156.0 seconds) and the CT–CR sequence (243.33 ± 113.83 seconds; P < 0.001). Overall time reduction by CR was 65.56%. Cinematic Rendering visualization of musculoskeletal and vascular anatomy was higher rated compared to CT visualization (P < 0.001 and P = 0.003), whereas CT visualization of parenchymal anatomy received a higher scoring than CR visualization (P < 0.001). No carryover effects were observed. A questionnaire revealed that students consider CR to be beneficial for medical education. These results suggest that CR has a potential to enhance knowledge acquisition and transfer from medical imaging data in medical education.  相似文献   

Lessons Our BSW Students Taught Us About Teaching Social Work in a Reservation Community     

Randall C. Nedegaard  Carenlee Barkdull  Bret A. Weber  Dheeshana S. Jayasundara 《Journal of Teaching in Social Work》2018,38(1):73-87

ABSTRACT

American Indians and Alaska Natives are underrepresented as social work students, social work educators, and within the profession in general. In addition, many historical and socioeconomic factors have contributed to disproportionality in higher education attainment between these students and those within other ethnic groups. Compounding the challenges, many students in reservation communities lack access to programs that provide social work degrees. Faculty based in a small university in the upper Midwest delivered a BSW program to students in a tribal community over a 3-year period and share pedagogical lessons learned from their students and the literature.  相似文献   

Processing procedural documents: A cognitive model for following written directions     

John T. Guthrie  Stan Bennett  Shelley Weber 《Educational Psychology Review》1991,3(3):249-265

This paper reviews empirical literature on how people use documents to perform tasks. We examine studies that have been published under the topics of: following written directions, reading maps, following instructions, using job performance aids, and processing procedural texts. Documents that contain a procedure, such as a set of directions, require transformation of information. Such transformation frequently requires converting a procedure represented verbally in a text into a procedure represented behaviorally in a performance. To accomplish this transformation, we propose that students must: (a) form a conceptual model of the performance; (b) encode procedures from the document; (c) engage in self-testing; and (d) conduct self-corrections to repair mistakes. We further propose that these operations are performed most efficiently with distinctive information resources. An overview of the task is likely to be most effective in facilitating conceptual model formation. Procedural information that emphasizes temporal characteristics of the performance will facilitate the encoding of procedures. A representation of the outcome (usually graphic) improves self-testing, and the comparison of the outcome with progress in the workspace leads to most effective self-correction. This process-resource interaction minimizes the number and complexity of transformations required to process procedural documents.  相似文献   

Effect of group size on avoidance learning in zebra fish,Brachydanio rerio (Pisces: Cyprinidae)     

Phyllis E. Gleason  Peter G. Weber  Suzanne P. Weber 《Learning & behavior》1977,5(2):213-216

The purpose of this study was to investigate the effect of density of fish on the rate of avoidance learning in a schooling fish. Naive adult zebra fish (Brachydanio rerio) were trained in a two-way aquatic shuttlebox, in isolation, in groups of two, or in groups of five. The number of trials to reach progressively more exacting levels of performance (1, 2, 3, … ,9 consecutive correct avoidance responses on 2 successive days), was used to quantify the rate of learning for individuals in the three groups. Using this measure, individuals in groups of five reached any given level of performance in fewer trials than individuals tested alone, which in turn reached the progressive criteria in fewer trials than individuals tested in pairs. In addition, the mean latency of response to the conditioned stimulus for individuals in groups of five was significantly lower than for individuals tested alone or in groups of two by Day 3 of the experiment. The rate of learning in zebra fish schools at these densities may be due to either a balance between imitation learning and conflict-inhibition among the fish or the elicitation of different behavioral responses by shock, depending upon environmental stimuli.  相似文献
