School based administrators must often determine the use of potentially powerful computing resources for the school's instructional program. While site level administrators have allocated many kinds of resources within the schools, the allocation of this new technology has little precedent. A decision guide is proposed to assist site level administrators. This guide explores three major sources of information to assist the site level administrator in making computer-related allocations. First, the context of the school, such as the school profile, and the district plan for instructional use of microcomputers, forms a basis for investigating the allocation of computing resources. Second, because both access to and applications for instructional computing resources are critical issues, the moral dilemma of equity-excellence is examined. Finally, empirical information from the existing literature and from a possible school based research effort are analyzed. A procedure for using this information to make decisions is proposed. By weighing these three sources of information, it is contended that the administrator is better able to allocate potentially powerful computing resources. Woven into the decision guide are specific examples from one administrator's efforts to make decisions about word processing at an intermediate school. The context, equity-excellence issues, and empirical information are examined in this particular site to illustrate one application of the guide and to share findings about word processing as an instructional tool. / Ed.

The primary purpose of this study was to determine the perceived attitudes of vocational administrators, vocational office education teachers, and marketing and distributive education teachers toward using microcomputers in vocational education programs. The sample forth is study was randomly selected from all vocational administrators , vocational office education teachers, and marketing and distributive education teachers employed by Texas School Districts. A total of 288 questionnaire were returned from the three vocational education groups. The return was seventy-seven percent. Statistical techniques included descriptive statistics, one-way, and two-way analyses of variance (ANOVA) to describe the responses and to test the seven null hypotheses. The results of the study was reported in two categories: statistical significance of the tested hypotheses, and the educational inferences of the vocational administrators' and vocational teachers' responses to questionnaire items. There were significant differences in the perceived general attitudes of the three groups. There were no significant differences in the perceived general attitudes of the three groups when categorized by levels of age, occupational experience, amount of computer training, and availability of microcomputers. There were no significant differences in hypotheses which tested for differences in the perceived attitudes of the three groups toward utilizing microcomputers for classroom instruction and supportive services.

This paper describes the building of a parallel converter for a high-speed serial bus. The high-speed serial port of the Macintosh personal computer is used to implement the bus, while an MC68000 Educational Computer Board is used to perform the serial-to-parallel conversion. The device's performance is evaluated, and possible methods for improving its performance are discussed.

Since the innovation of computers some 40 years ago and the introduction of microcomputers in 1975, computers are playing an active role in education processes and altering the pattern of interaction between teacher and student in the classroom. Computer assisted learning has been seen as a revolution in education. In this research, the author has studied the impact of using microcomputers on mathematical education, particularly at the Hong Kong tertiary level, in different perspectives. Two computer software packages have been developed on the microcomputer. The consideration of the topic to be used in the computer assisted learning was arrived at in earlier surveys with students who thought that computers could give very accurate solutions to calculations. The two software packages, demonstrating on the spot the error that would be incurred by the computer, have been used by the students. They are both interactive and make use of the advantages of the microcomputer's functions over other teaching media, such as graphics facility and random number generator, to draw to the students' attention awareness of errors that may be obtained using computers in numerical solutions. Much emphasis is put on the significance and effectiveness of using computer packages in learning and teaching. Measurements are based on questionnaires, conversations with students, and tests on content material after the packages have been used. Feedback and subjective opinion of using computers in mathematical education have also been obtained from both students and other teachers. The research then attempts to examine the suitability of applying computer assisted learning in Hong Kong education sectors. Some studies on the comments made by students who participated in the learning process are undertaken. The successes and failures in terms of student accomplishment and interest in the subject area as a result of using a software package is described. Suggestions and recommendations are given in the concluding chapter.

In 1981 the author submitted that "many of the (then) more recent school syllabuses remain disjointed and give expression still to a school mathematics course as step-by-step progression through a list of disparate topics". The position has not changed. It is not yet generally accepted that there can no longer be an accepted body of mathematical knowledge that needs to be taught. The rapid development of new technology and the introduction of the microcomputer should enable the 'modern' mathematics of the early 1960's to enhance the mathematical experiences of pupils in a practical and comprehensible way and prompt a new style of teaching and learning mathematics. There is, however, a fundamental core of mathematics which must inevitably find a place in the school mathematics curriculum. In Part I of the thesis the emphasis is on a method of presentation of certain key topics which illustrate the basic pattern of a group structure. Former complications at school level of putting plane geometry on a logical footing have to be avoided. The use of complex numbers highlights significant and sometimes rather difficult geometrical ideas. In Part 11 the author attempts to show how some of these ideas may be presented to extend the basic pattern to that of linear algebra. The work culminates in Part III with the use of linear complex algebra to present more vividly the symmetries of the Platonic solids. The author anticipates the realistic presentation of the aesthetic side of 3-dimensional geometry and takes a look at its possible presentation through the medium of the microcomputer. At this early stage of the development of the ideas to be discussed, there can be no formal testing of the results by quantitative analysis. Evaluation of the viability of the proposals will be qualitative and the comments of 'critical academic friends' will be included. The originality demanded of a piece of research goes beyond the exposition. Here it will consist of new insights into ideas appropriate to senior pupils in schools and a rewriting of existing material often thought to be beyond their scope. The work is supported by suggested lesson sequences, transcripts of recorded presentations, and examples of students' work. Subsequent development must face the question of assessment and evaluation at sixth-form level of the proposed new style of teaching mathematics. The author makes some suggestions in the concluding chapter.

The Deployable Navigation System (DeNS) is a prototype system designed to facilitate Command and Control during over the horizon small boat operations. It is designed to allow small boats to deploy from their host ships with a Bluetooth GPS (Global Positioning System) receiver and PDA (Personal Digital Assistant) running the appropriate software which provides a real time navigational picture in terms of position and relation to a predetermined track. This same data is shipped immediately back to the control ship via a wireless network and displayed on a laptop computer to allow the mission commander to monitor the small boatâ s progress and position, also in real time. The small boatâ s relation to the track is compared on every received fix and appropriate indicators are displayed to inform both users if a predetermined distance from track (track tolerance) has been exceeded. It utilizes jpg formatted maps that are derived directly from the Digital Nautical Chart (DNC) library overlaid with track information. Positions received from the GPS are converted to pixel coordinates that correspond to their original positions on the jpg chart and plotted, providing an electronic display that is very similar in appearance to the traditional plot maintained on paper charts.
