Metacognition as a Basis for Learning Support Software     

Christine Brown  John Hedberg  Barry Harper 《Performance Improvement Quarterly》1994,7(2):3-26

In order to understand the task of instructional designers who produce learning support software, this paper reviews the influence of learning theory on instructional design, recent developments in computer technology, and the evolving role of the instructor as a facilitator of higher-order thinking. Constructivist principles of learning and an appreciation for the fact that the learner must become more independent and skilled in metacognitive self-assessment and self-management are fundamental to this changing role. Two cognitive tools that provide learner/user support for personal construction of knowledge systems are “MindMap” and “Learning FourMat Processor.” These tools are examined in the light of current learning theory and a recent study comparing the work of novice and expert writers using different forms of performance support. Recommendations are made for the development of a more complete set of cognitive tools that enables users to construct their own multimedia knowledge systems based on higher-order thinking and problem solving.  相似文献

Scanning technology selection impacts acceptability and usefulness of image-rich content     

Kristine M. Alpi  James C. Brown  Jr.  Jennifer A. Neel  Carol B. Grindem  Keith E. Linder  James B. Harper 《Journal of the Medical Library Association》2016,104(1):15-23

Objective

Clinical and research usefulness of articles can depend on image quality. This study addressed whether scans of figures in black and white (B&W), grayscale, or color, or portable document format (PDF) to tagged image file format (TIFF) conversions as provided by interlibrary loan or document delivery were viewed as acceptable or useful by radiologists or pathologists.

Methods

Residency coordinators selected eighteen figures from studies from radiology, clinical pathology, and anatomic pathology journals. With original PDF controls, each figure was prepared in three or four experimental conditions: PDF conversion to TIFF, and scans from print in B&W, grayscale, and color. Twelve independent observers indicated whether they could identify the features and whether the image quality was acceptable. They also ranked all the experimental conditions of each figure in terms of usefulness.

Results

Of 982 assessments of 87 anatomic pathology, 83 clinical pathology, and 77 radiology images, 471 (48%) were unidentifiable. Unidentifiability of originals (4%) and conversions (10%) was low. For scans, unidentifiability ranged from 53% for color, to 74% for grayscale, to 97% for B&W. Of 987 responses about acceptability (n=405), 41% were said to be unacceptable, 97% of B&W, 66% of grayscale, 41% of color, and 1% of conversions. Hypothesized order (original, conversion, color, grayscale, B&W) matched 67% of rankings (n=215).

Conclusions

PDF to TIFF conversion provided acceptable content. Color images are rarely useful in grayscale (12%) or B&W (less than 1%). Acceptability of grayscale scans of noncolor originals was 52%. Digital originals are needed for most images. Print images in color or grayscale should be scanned using those modalities.  相似文献   

“You’re the best around”: an argument for playoffs and tournaments     

Aaron Harper 《体育哲学杂志》2016,43(2):295-309

Recent articles, including those by Dixon and Torres and Hager, criticize tournament playoffs, primarily for reasons of fairness and integrity. Many suggest that playoff and tournament prominence reflect monetary and entertainment interests rather than the pursuit of athletic excellence. Nevertheless, tournament playoffs are increasingly popular. While the concerns are serious, in this paper I defend the overlooked value of playoffs and tournaments. Playoff critics employ too narrow a conception of the best team and too limited a view of excellence. Rather, playoffs and seasons highlight distinct and valuable conceptions of athletic excellence. To better capture this, I consider two alternative championship formats: the hybrid system and championship pluralism. The hybrid system includes a playoff informed by the regular season. Despite its apparent advantages, I reject the hybrid approach. Instead, I propose championship pluralism as a preferred championship model.  相似文献   

Adult higher education opportunities: An evaluation of sources of information     

Dr. Patricia Harper Apt 《Innovative Higher Education》1978,3(1):31-33

How do adults learn about higher education opportunities that are available to them? Few studies have investigated this question. The Institute for Communication Research study of the promotion of adult learning programs in the United States and the Center for Research and Development in Higher Education study of higher education opportunities for adults focused on the channels chosen by educational institutions for communicating information. This study investigates adult audiences' attentiveness and evaluation of various sources of information about opportunities for higher education. Generally, it was found that personal sources of information were evaluated more highly by adults interested in pursuing higher education than by those who were not interested. The evaluation of mass media information sources were not significantly different, however, between interested adults and not-interested adults.  相似文献
