Computerized prompting partners and keystroke recording devices: Two macro driven writing tools

Recent research into composing processes has focused on instructional intervention strategies that promote effective composition practices within computerized writing environments. The field of computers and composition has benefitted both from advances in computing tools and developments in learning theory. The innovative computer tool discussed in this paper uses the macro-command language of a full-featured word processor to enact strategic support designed to help writers with their written work. From a theoretical standpoint, this tool created a writing environment based on Vygotskian theory of mediated learning and was grounded in an instructional strategy known as “procedural facilitation.” To evaluate the effectiveness of this computerprompting tool, a second macro application was used to log student keystrokes, thereby tracking student writing development, revisionary practices, and keystroke reactions to the prompting partner. Students using the prompting tool enacted divergent and convergent thinking assistance that appeared at the bottom of their computer screens while the system saved a process record of their keystrokes. Procedures for creating macro-driven prompting programs and keystroke-logging devices are discussed. Additionally, a catalog of prompts and summary of keystroke-mapping benefits are provided. Finally, our research using the macro-driven prompting partner and keystroke-register tool is detailed.     

The limited value of planning in education: Getting back to the basics isn't all about curriculum

In these times of tight budgets and political intoleance for taxation, public schools, particularly urban public schools, will continually have to look for ways in which to spend less while dealing with ever-increasing societal problems. While the ability of schools to improve the overal “product” with less resources is highly suspect, this article addresses one way in which spending less might actually improve school perfomance. The best planners in the best schools should be the administration, techers, students, parents, and the comminitu at large, and not outside esxperts hired to improve a school's “comprehensive” or “strategic” plan. By forcing the segments of the public that have the largest stake in the educational outcomes of schools to work together to plan for the future, schools will improve the efficacy of their staffs, their students, and allow parents the self-satisfaction of playing an important role in their children's education. An improtant side effect of such a method may be an increasing awareness by the public of the difficulties that schools face, and perhaps a better understanding of the important need for higher expenditures. His research interests include professionalism, collective bargaining, and educational reform. His articles have appeared inPeople and Education, and a recent article has been aceepted for publication in theJournal of Collective Negotiations in the Public Sector.     

Pricing policy and the college choice process

Following the presentation of a marketing management paradigm for higher educational institutions, this paper discuses some aspects of the pricing policy process in colleges and universities. A statistical model of the college choice process is developed, and some empirical results related to the effects of price, among other factors, on the collegechoice decision-making behavior process of high school seniors are presented and interpreted. The two most important factors affecting the college choice process are seen to be college quality and price-related considerations. Marketing implications of these results are discussed.Presented at the Annual Forum of the Association For Institutional Research, Houston, Texas, May 1978.     

The data collection matrix model: A tool for functional area and program evaluation

The management and utilization of collected data is crucial in evaluating programs and functional area effectiveness. Various assessment instruments may address similar functional areas of the college, yet we often fail to compile these data for comprehensive evaluation. The data collection matrix makes possible the integration of functional area data from numerous assessment sources and presentation of the information in a unified composite report. The matrix model will be discussed in relation to the various assessment instruments and the evaluation of functional areas and programs. This paper is directed toward institutional researchers who may wish to adapt the model to their own institution.Presented at the Annual Forum of the Association for Institutional Research, Louisville, KY, May 13–16, 1990.     

Categorical color coding by pigeons

Pigeons were trained on two independent tasks. One involved red and yellow hues, the other involved blue and green hues. For half of the birds, the two tasks were the same (i.e., both tasks were either matching-to-sample, or oddity-from-sample). For the remaining birds, the two tasks were different (i.e., one task was matching-to-sample; the other task was oddity-from-sample). Following acquisition, the pigeons were exposed to test trials on which either the correct or the incorrect comparison hue was replaced with one of the hues from the other task. On yellow-sample trials and on green-sample trials, the pigeons performed as if they had a common code for yellow and green. When there was one comparison available that was appropriate to the “yellow/green” code, performance remained high; but when either both comparisons or neither comparison was appropriate to the “yellow/green” code, performance dropped. The pigeons also tended to code red samples as green and to code blue samples as yellow. The results indicate that pigeons can categorically code colors under conditions that rule out a failure to discriminate among the colors.     

Enhancing the facilitation of online groups in higher education: a review of the literature on face-to-face and online group-facilitation

There still appears to be a gap between what online learning promises and what it can deliver in terms of student learning. Developments in online pedagogies and professional learning appear to lag behind the developments in technology and the promised benefits of technological transformation may not be realised. In this paper, we bring together perspectives that highlight vital aspects of online group-learning by reviewing the group-facilitation literature and the latest online learning literature to interrogate the pedagogical theories and practices currently used in online group-learning in higher education. We specifically focus on the interpersonal interactions between teachers and students, which are described in the online learning literature using the terms instructor immediacy, teaching presence, and social presence. We note differences in the literature regarding how teacher presence is interpreted and enacted and we expound the importance of the personal characteristics of the online teacher. Finally, we provide some signposts that might help course designers and teachers to improve online group learning: the intentional use of effective online learning pedagogies; a deeper understanding of what constitutes teacher presence; and strategies to enact that teacher presence with online groups. Recommendations for further research in online group facilitation are provided.     

Video-assisted thoracoscopic surgery （VATS） for bilateral primary spontaneous pneumothorax

Objective:To review our experience of the treatment of bilateral primary spontaneous pneumothorax (PSP) by video-assisted thoracoscopic surgery (VATS). Materials and methods: Retrospective chart review was followed by an on-clinic or telephone interview. Patients were cared for by one thoracic surgeon in four medical centers or community hospitals in Northern and Central Taiwan. Thirteen patients with bilateral PSP underwent bilateral VATS simultaneously or sequentially from July 1994 to December 2005. Results: Twelve males and one female, with age ranging from 15 to 36 years (mean 23.1 years), were treated with VATS for bilateral PSP, under the indications of bilateral pneumothoracis simultaneously (n=4) or sequentially (n=9). The interval between the first and second contra-lateral VATS procedure for non-simultaneous PSP patients ranged from 7 d to 6 years. Eleven of 13 patients (84.6%) had prominent pulmonary bullae/blebs, and underwent bullae resection with mechanical or chemical pleurodesis. The mean operative time was (45.6±18.3) min (range 25-96 min) and (120.6±28.7) min (range 84-166 min) respectively for the non-simultaneous (second VATS for the recurrence of contralateral side after first VATS) and simultaneous (bilateral VATS in one operation) procedures. There was no postoperative mortality. However, prolonged air leakage (>7 d) occurred in one patient (7.7%) who recovered after conservative treatment. The mean duration of chest tube drainage was 3.1 d and the median follow up period was 3.4 years. Conclusions: VATS is a safe and effective procedure in the treatment of bilateral PSP. Bilateral VATS is only recommended for patients with simultaneously bilateral PSP, because the incidence of recurrence, even with visible bullae, was not so high in my group and in some previous literature. Bilateral VATS in a supine position should only be used in selective cases, because of possible pleural adhesion or hidden bullae on the posterior side.
