This article presents a prototype of a computerized grammar kit written in PROLOG and implemented on a LISP machine. The kit consists of tools and examples intended to be used by children interested in exploring language. A grammar written in PROLOG using this tool kit can be used not only to parse, but also to generate, sentences. A serious shortcoming of PROLOG for children is that when a program misbehaves one must understand its complex operational semantics. A major tool in the grammar kit to alleviate this problem is a dynamic graphical tracer which uses a backtracking turtle. This allows the user to see a parse tree as it is being built and, as a side-effect, gives a better understanding of PROLOG's chronological backtracking.The research reported herein was supported by the Swedish Board for Technical Development (STU) and Atari Research, Cambridge, Massachusetts. 相似文献

The aim of the study was to investigate what kinds of assessment practices classroom teachers and special educational needs (SEN) teachers use in assessing first grade students' pre-reading skills (letter knowledge and phonological skills). Further, we investigated to what extent teachers were able to identify difficulties in pre-reading skills of the children with the lowest achievement scores. The accuracy of teacher ratings of students' pre-reading skills was studied by comparing teacher ratings to actual test scores. The data from two Finnish longitudinal studies were used: JLD sample (class teachers, n = 91; SEN teachers, n = 51; 200 students) and First Steps sample (class teachers, n = 136; SEN teachers, n = 34; 598 students). Results showed first, that most classroom teachers used qualitative assessment and SEN teachers also relied on tests. Secondly, although teacher ratings correlated with the test scores, closer investigation of sensitivity and specificity of the teacher ratings revealed that a number of children in need of extra support for their early reading development according to test scores remained unidentified. Moreover, there were some students identified by the teacher to have difficulties despite test scores not confirming that. The findings underline the importance for developing more specific and reliable assessment tools for teachers to use for pedagogical purposes, and respectively, the need to pay more attention to early identification of reading difficulties in teacher training program curricula. 相似文献

Rapid advances in technology, particularly with the Internet, have led to the availability of numerous tools to support teaching
and learning. This study involved the use of an Internet application, Connecting Communities of Learners (CCL), in courses
for prospective teachers. Unlike earlier studies involving the use of the CCL, the context of this study related to full-time
graduate students who used the CCL to augment weekly face-to-face instruction. An interpretive study was undertaken to ascertain
student and teacher perceptions of the learning environments associated with the use of the CCL. Through the use of the CCL,
students were able to be autonomous in regard to their own learning, co-participate with their peers and the instructor, and
establish and maintain a community of learners in which participants could interact with others as co-teachers and co-learners.
The CCL was perceived as a useful tool for building learning environments in which all participants can contribute written
texts as evidence of what is known and as objects from which others can learn.

The lectures for two modules which together comprise an introductory course on textiles and textile manufacturing comprising some 70 hours of lectures were replaced by computer-based multimedia learning material requiring a similar amount of study time. In a student project the reactions and attitudes of students to taking the computer-based course were elicited through two questionnaires. The results of the student project indicated that the data was worthy of further study, in particular, the responses to the second questionnaire. In this paper these data are analysed in detail. The attitudes and reactions of the students are linked to features of the material and its use, and to possible more general attitudes of the students. Consideration is given to the study behaviour of the students and ways in which the courseware might be improved are proposed. 相似文献

Part-Time Faculty in Colleges and Universities: Trends and Challenges in a Turbulent Environment 总被引:1,自引:0,他引:1
Kenneth H. Charfauros William G. Tierney 《Journal of Personnel Evaluation in Education》1999,13(2):141-151
The fastest-growing group in postsecondary education is part-time faculty. The authors examine why the number of part-time faculty has increased so rapidly and then discuss some of the problems that part-timers face. Part-timers are increasing in academe, and administrators need to treat and evaluate them effectively and fairly. The authors recommend mentoring, job security, compensation, and self-worth as ways to improve performance. 相似文献

This paper describes and assesses the effectiveness of the Meyerhoff Scholars Program at the University of Maryland, Baltimore County (UMBC). The Program is designed to increase the number of underrepresented minorities who pursue graduate and professional degrees in science and engineering. Until 1996 the program admitted African American students exclusively, and the current study focuses only on students from that group. The Meyerhoff students have achieved higher grade point averages, graduated in science and engineering at higher rates, and gained admittance to graduate schools at higher rates than multiple current and historical comparison samples. Student survey and interview data revealed that a number of program components were viewed as being especially important contributors to students' academic success: Program Community, Study Groups, Summer Bridge Program, Financial Support, Program Staff, and Research Internships and Mentors. © 2000 John Wiley & Sons, Inc.

Increasingly, the long‐term success of a company resides in its ability to develop and market successful new products in a cost‐and time‐effective manner. In general, Japanese companies have outperformed their Western counterparts in bringing new products to market over the last 10 to 20 years. This has given them a substantial advantage in long‐term economic development. The authors hypothesize that the differences between the dominant models of corporate culture in Japan and the U.S. account for the Japanese advantage. In comparison to U.S. companies, Japanese companies tend to emphasize long‐term leadership, decentralized decision making, a flatter work structure using cross‐functional work teams, and rewarding teams for the ability to learn from mistakes. As a result of these differences, Western companies are more likely to utilize “single, loop” learning, where new products are developed using established (and unquestioned) procedures. Conversely, Japanese companies rely on “double‐loop” or “deutero” learning styles, which encourage employees to leverage their past experiences when proposing new product innovations. The authors conclude by outlining a research program for testing their as‐gumptions about the relations among nationality, corporate culture, learning styles, and new product success. 相似文献

Self‐reported internalizing symptoms of seriously emotionally disturbed (SED) and regular education students in grades 4–6 were compared using the Internalizing Symptoms Scale for Children. All participants were African American and from an urban public school district in the Southeastern United States. Each of the two study groups consisted of 50 participants (35 boys, 15 girls) who were matched by gender and socioeconomic status. The SED group reported significantly higher levels of internalizing distress than the regular education group. In contrast to previous findings, there was no significant gender difference in self‐reported internalizing symptomatology in the present study. A discriminant function analysis found that the ISSC scores were able to correctly classify 91% of the participants into their respective educational group. Results of this study provide additional evidence of the construct validity of the ISSC, a recently developed and unique self‐report measure. Results are discussed in terms of future research needs and educational/clinical practice with students who have emotional and behavioral disorders. © 1999 John Wiley & Sons, Inc. 相似文献
