Automated finger spelling by highly realistic 3D animation

We present the design of a new 3D animation tool for self‐teaching (signing and reading) finger spelling—the first basic component in learning any sign language. We have designed a highly realistic hand with natural animation of the finger motions. Smoothness of motion (in real time) is achieved via programmable blending of animation segments. The hand is utilised by a programme that automatically converts text to finger spelling with controllable playback speed and playback views. The programme can be operated in two modes for two basic applications: learning to read (finger spelling) and learning to sign. For both modes, multi‐sided views are provided. In addition, for the signing mode, a mirror view is provided for the common technique of using a mirror for feedback in practising finger spelling. An additional view revealing the joint structure of the hand allows the signer to practise the subjective view without having to guess the position of the fingers. This is the first example of highly realistic 3D animation that can be used practically to teach a basic aspect of sign language. The method is applicable more generally to sign language, and this finger‐spelling application should be regarded as a first step toward the extension of highly realistic 3D animation to sign language in general.  相似文献   

Performance equivalency between computer‐based and traditional pen‐and‐paper assessment: A case study in clinical anatomy          下载免费PDF全文

The time, material, and staff‐consuming nature of anatomy's traditional pen‐and‐paper assessment system, the increase in the number of students enrolling in medical schools and the ever‐escalating workload of academic staff have made the use of computer‐based assessment (CBA) an attractive proposition. To understand the impact of such shift in the assessment method, an experimental study evaluating its effect on students’ performance was designed. Additionally, students’ opinions toward CBA were gathered. Second‐year medical students attending a Clinical Anatomy course were randomized by clusters in two groups. The pen‐and‐paper group attended two sessions, each consisting of a traditional sectional anatomy steeplechase followed by a theoretical examination, while the computer group was involved in two similar sessions conducted in a computerized environment. At the end of each of the computer sessions, students in this group filled an anonymous questionnaire. In the first session, pen‐and‐paper group students scored significantly better than computer‐group students in both the steeplechase (mean ± standard deviation: 66.00 ± 14.15% vs. 43.50 ± 19.10%; P < 0.001) and the theoretical examination (52.50 ± 12.70% vs. 39.00 ± 21.10%; P < 0.001). In the second session, no statistically significant differences were found for both the steeplechase (59.50 ± 17.30% vs. 54.50 ± 17.00%; P = 0.085) and the theoretical examination (57.50 ± 13.70% vs. 54.00 ± 14.30%; P = 0.161). Besides, an intersession improvement in students’ perceptions toward CBA was registered. These results suggest that, after a familiarization period, CBA might be a performance equivalent and student accepted alternative to clinical anatomy pen‐and‐paper theoretical and practical examinations.

Equality of educational opportunity at racially isolated schools: Balancing the need for teacher certification with teacher shortage     

James E. Bruno  George A. Marcoulides 《The Urban Review》1985,17(3):155-165

Providing for equality of educational opportunity at racially isolated schools continues to be an important area of concern for educational policy makers. Quality teachers to staff instruction programs at these schools is essential to promoting equal opportunity for minority groups. Unfortunately, these schools continue to suffer chronic teacher shortages. Recently, California implemented a teacher certification examination (CBEST) designed specifically to improve the quality of teachers entering the profession. An unintended consequence of the certification movement was the exacerbation of the teacher shortage problem at racially isolated schools. The purpose of this study is to examine the characteristics of teachers who passed and failed the CBEST. The study finds that failure rates are highest among minority teachers that are presently employed. The study also finds that the mathematics knowledge subscale scores best discriminate those passing from those failing the CBEST. An analytical approach for determining optimal cutoff scores on the CBEST which balances the need for certification with the problem of teacher shortage is proposed.  相似文献   

Mathematics attainment at inner-city schools: Establishing the need for systematic formative evaluation practices     

Robert R. Barner  Dr. James E. Bruno 《The Urban Review》1991,23(4):251-270

Recently there has been a great amount of research and professional educator interest in at-risk, poor academically attaining students, especially low socioeconomic status students at U.S. inner-city schools. A major factor that has been hypothesized in the research literature as being associated with poor academic attainment is the lack of critical and timely instructional feedback or formative evaluation. Using a sample of 130 inner-city senior high school students, the perceived quality and quantity of formative evaluation received by these students at their elementary and secondary school levels were assessed. in addition, each student was given a mathematics (pre-algebra) assessment using both a one and two-dimensional format (recognition plus confidence) to determine present levels of mathematics attainment. Finally data were collected from the cumulative grade-level folders of a subset of these students, especially norm-referenced data (NRT) in mathematics, to examine their relationship to scores on the Scholastic Aptitude Test-Quantitiative portion. The study finds that in addition to extremely poor mathematics attainment and poor formative evaluation practices there is little association between SAT (quantitative) scores and the grade-level (mathematics) NRT scores. These findings suggest that parents cannot depend on traditional norm-referenced measures to indicate actual mathematics attainment as these students are progressing through the schools. These findings also challenge urban school administrative personnel to reassess the use of NRT measures to monitor student progress and to develop more comprehensive and systematic formative evaluation procedures and practices for individual students as they progress through each grade level.  相似文献   

Doing time—Killing time at school: An examination of the perceptions and allocations of time among teacher-defined at-risk students     

Dr. James E. Bruno 《The Urban Review》1995,27(2):101-120

“Doing time” is an expression that is generally associated with prisoners who are disconnected from society and find themselves counting the days and minutes until their release from prison. In many respects, at-risk students attending our nation's large, urban, inner-city middle and high schools also consider themselves as not being connected to school or society and to be “doing time” in the classroom. Qualitative and subjective impressions of doing time at school have become the theme of many movies, books, and research articles. This study extends this qualitative type of research by quantitatively framing time allocation preferences and temporal dominance characteristics for a large sample of teacher-perceived “at-risk” students at several large urban high school sites. A sample of normal attaining students at the same school site served as a comparison group. The findings of this research effort generally support other more qualitative studies and indicate that there are strong preferences in at-risk students toward nondirected time-consuming activities (i.e., hanging out, video games, watching TV, etc.) with low-directed to nondirected time preference ratios. Normal attaining students had the reverse pattern, i.e., higher-directed to nondirected time preference ratios and higher preferences toward directed time-consuming activities that might be associated with investments in the schooling process (homework, studying, personal development, etc.). Interpretation of the circles test, a projective psychological procedure for establishing temporal dominance for at-risk students, revealed a general lack of recognition and connectiveness between past, present, and future events in their life and weak temporal dominance or orientation toward the future.  相似文献

Reflective practicum in higher education: the influence of the learning environment on the quality of learning     

Andreina Bruno  Giuseppina Dell’Aversana 《Assessment & Evaluation in Higher Education》2018,43(3):345-358

Sustaining students in becoming reflective practitioners is considered as a valued outcome of higher education. The paper aims to evaluate the impact of the learning environment conditions inspired by Schön’s theory of reflective practicum, by discussing a case study of a master’s degree class. The learning environment was designed to sustain reflective practice and meaningful engagement through professional practice simulation, problem-based learning and reflective writing. Unlike much of the research into reflective learning, the quality of learning was evaluated by assessing the use of reflective practice in students’ weekly journaling, rather than measuring students’ satisfaction or perceptions of effectiveness. Two hundred and six journal entries of 23 students were assessed and used in a quantitative analysis based on a linear mixed-effects model. Findings indicated that the reflective practicum has an incremental effect on students’ reflective practices and that reflective practice is dynamic and sensitive to specific learning environment conditions. In conclusion, students’ co-responsibility of the learning environment allowed by the professional practice simulation appears to foster meaningful and reflective learning. Conversely, conditions that stimulate only cognitive engagement have little impact or even inhibit reflective practices. Practical implications of the use of reflective journal are discussed.  相似文献   

Higher education for public value: taking the debate beyond New Public Management     

Bruno Broucker  Kurt De Wit  Jef C. Verhoeven 《高等教育研究与发展》2018,37(2):227-240

Many higher education (HE) system reforms in the past decades have been built on the paradigm of New Public Management (NPM). However, these reforms have not allowed HE to fully take its value for society into account. In recent years a growing call can be heard to orient the HE sector towards more collaboration, a focus on a larger set of socio-economic objectives instead of on performance alone, less pressure, more trust and legitimacy. In this article, it is stated that NPM has not sufficiently enabled the creation of public value (PV) by the HE sector. This article provides (1) insight into the flaws of NPM, (2) an understanding of PV for HE and (3) a new model to study HE reforms built on the concept of PV.  相似文献   

Divide to connect: Reorganization through R&D unit spinout as linking context of intra-corporate networks     

Bruno Cirillo  Stefano Breschi  Andrea Prencipe 《Research Policy》2018,47(9):1585-1600

The paper examines the formation of clique-spanning ties in intra-corporate co-invention networks, by focusing on the impact of R&D unit spinouts. Using data on thirty-one spinouts in eight large U.S. information and communication technology corporations, we show that the reorganization of R&D units through corporate spinouts is associated with an increase in the extent to which inventors employed in the unit collaborate with inventors located in other cliques within the corporate co-invention network. Interestingly, the spinout effect spills over to all members of the clique of spun-out inventors, also including those who remain with the parent firm. The interpretation of these empirical findings, grounded on existing theories and on the views of inventors and executives involved in the reorganization events, suggests that corporate spinouts generate a shock in intra-corporate research collaboration dynamics, which loosens clique lock-in effects and contributes to reset cliques’ boundaries in the intra-corporate research network.  相似文献
