The Interplay of Intimations and Implementations: Generating New Discourse With New Symbolic Tools     

Anna Sfard 《学习科学杂志》2013,22(2-3):319-357

The analysis of the Batteries and AIDS episodes presented in this article is guided by the assumption that thinking can be conceptualized as an activity of communication, and learning can be regarded as modifying and extending one's discursive ways. Within this framework, 1 of the aims of mathematical learning is to become skillful in the discursive use of designated symbolic artifacts supposed to mediate solving certain types of problems. My analysis of the learning episodes is aimed at uncovering the ways in which the discursive uses of such new symbolic tools were interactively constructed by the students. I argue that the construction process is extremely complex because of a certain inherent circularity of this process. The analysis reveals that this difficulty may be overcome by the gradual dialectic adjustment of former discursive habits to new contexts. The adjustment happens gradually, through cycles of intimations about the applicability of the old habits followed by implementations in which this applicability is examined. This intricate interplay of intimations and implementations is found in both the Batteries and the AIDS episodes and is presented in detail in the article. I also show that, with time, students significantly increased their mastery of this particular discursive mechanism.  相似文献   

Using a Retrospective Pretest to Measure Learning in Professional Development Programs     

Leila González Sullivan  Karen J. Haley 《Community College Journal of Research & Practice》2013,37(3-4):346-362

Millions of dollars are spent annually on professional development, and designers of training events recognize they must demonstrate to all stakeholders the value added by these programs. The purpose of this study was to measure the learning that occurred during professional development seminars for community college academic department chairs. The research question was the following: What increases in knowledge and skills did program participants attribute to their training experience? Using Alliger and Janak's model for levels of learning as a conceptual framework, data were collected through a preliminary questionnaire on learning needs, session and overall evaluations, and a retrospective pretest addressing 35 knowledge and skill areas. Statistical analysis of retrospective pretest results for six areas identified by participants as priorities indicated that participants felt learning had occurred as a result of the seminar (significant at .0001 level). The retrospective pretest instrument was deemed an effective tool for evaluating learning in continuing education offerings, higher education professional development events, and similar settings.  相似文献   

Rapid Response Skills Training     

Anna Faye Kelley-Winders 《Community College Journal of Research & Practice》2013,37(11):927-929

Mississippi Gulf Coast Community College's (MGCCC) long-term commitment to providing workforce training in a post-Katrina environment became a catalyst for designing short-term flexible educational opportunities. Providing nationally recognized skills training for the recovery/rebuilding of communities challenged the college to develop innovative, rapid response programs for the construction and health care industries.  相似文献

Dutch Dyslexia in Adulthood: Core Features and Variety     

Judith Bekebrede  Aryan van der Leij  Anna Plakas  David Share  Eleni Morfidi 《Scientific Studies of Reading》2013,17(2):183-210

This study aimed to explore how alphabetic readers learn to read Chinese. First-year Chinese beginning learners who are skilled English readers were tested for their sensitivity to the visual-orthographic structures of Chinese characters. The study also explored the effect of the frequency of the characters in their curriculum on performance of a lexical decision and naming task. The students' linguistic knowledge about the characters was also tested. Results showed that the beginning learners were sensitive to the structural complexity of characters, they accepted simple characters more quickly and more accurately than compound characters, and they responded faster and more accurately to high-frequency than to low-frequency characters. Sensitivity to the structural composition of the character was also revealed: The learners rejected noncharacters containing illegal radical forms faster and more accurately than those containing legal radical forms in illegal positions, which in turn were rejected faster and more accurately than those containing legal radical forms in legal positions. A significant frequency effect was also found in the naming task, though the effect of structural complexity was not significant. These results suggest that perceptual learning plays an important role in early nonalphabetic learning by alphabetic readers. Both cross-writing system differences and second-language status may have an impact on such learning.  相似文献
