The instruction of mathematically talented students (MTS) in heterogeneous classes is an issue of debate. Questions of equity, differential instruction, teacher awareness of their talented students’ needs, and their willingness and competence to face the challenges of nurturing these students are all raised within this context. Our international study compared South Korean, American, and Israeli teachers of mathematics perspectives concerning their (a) perceived competence to teach MTS (b) perceived competence in addressing MTS’ needs through differential instruction, (c) support for separation of MTS into special math classes, and (d) equity views concerning MTS’ needs. Data was collected by means of a questionnaire presented to 80 South Korean, 145 Israeli, and 58 American teachers of mathematics. Findings suggested that most teachers in these countries perceived themselves as competent to teach MTS, while very few of the participants supported the separation of MTS into special classes. South Korean teachers perceived themselves to be less competent in teaching MTS as well as in applying differential instruction and agreed more than their foreign counterparts that the fostering of mathematically weak students is more important than the fostering of MTS. Teachers who had some mathematical background appeared to perceive themselves as more competent to teach MTS than teachers who had no mathematical background. Teachers who predominantly taught large classes felt less competent to teach MTS than teachers who predominantly taught medium-sized classes. Findings were partially interpreted within the perspective of cultural differences. Recommendations for teachers’ professional development are drawn. 相似文献

This article is an exploration of the emerging narratives on learning and teacher education in the United States and Hong Kong, as found in official policy statements and curriculum documents. Particular attention is given to Hong Kong's initiative in implementing an interdisciplinary liberal studies curriculum, and the continued professional development of teachers for this proposed change. This recent trend is used to illustrate the possibilities for a broader vision of creating and substantiating knowledge and learning in teacher education programs in the United States. 相似文献

This paper considers studying changes in teachers’ perspectives regarding the teaching of mathematically talented students learning in heterogeneous classes. We investigate these changes through a case study of Rona, a teacher who participated in the professional development program “From One End to the Other” held in The David Yellin College of Education, Israel. The analysis focuses on 3 categories of change: awareness, practice, and self-efficacy. The results concerning Rona, 1 of the participants, demonstrate a rise in awareness of talented students, a change in the ways of meeting the needs of these students, and a rise in self-efficacy regarding the teaching of talented students. Moreover, it was found that changes in 1 category are interwoven with changes in the other categories. 相似文献

Although three-dimensional (3D) printing technology is increasingly used in dental education, its application regarding the provision of online visual augmented feedback has not been tested. Thus, this study aimed to: (1) develop two generations of multicolored 3D-printed teeth that provide visual augmented feedback for students conducting the cavity preparation process, (2) assess students' clinical performance after training on the 3D models, and (3) acquire student feedback. For the first-generation model, augmented feedback was obtained from five 3D-printed teeth models for five cavity preparation procedures. Each model comprised three layers printed in green, yellow, and red indicating whether preparation was acceptable, limited, or unacceptable, respectively. The study used a crossover design in which the experimental group trained on five multicolored models and 10 standard plastic teeth, and the control group trained on 15 standard plastic teeth. Students gave positive feedback of the methodology but complained about the printed material's hardness. Therefore, a second-generation model was developed: the model's occlusal plane was replaced with a harder printed acrylic material, and the experiment was repeated. During training, instructors provided external terminal feedback only for performance on standard plastic teeth. Manual grades for cavity preparations on standard plastic teeth were compared. No significant differences were found between the control and experimental groups in both generations' models. However, less instructor time was needed, and similar clinical results were obtained after training with both generations. Thus, multicolored 3D-printed teeth models promote self-learning during the process of acquiring manual skills and reduce student dependency on instructors. 相似文献

The use of digital environments for both learning and assessment is becoming prevalent. This often leads to incongruent situations, in which the study medium (eg, printed textbook) is different from the testing medium (eg, online multiple-choice exams). Despite some evidence that incongruent study-test situations are associated with inferior achievements, the effect of study-test congruency has not been investigated systematically. Here, we examine this question in the context of digitally displayed versus printed text comprehension using a full-factorial experimental design. One hundred and twelve university students participated in the study. They studied an expository text in one medium (print or digital) and then, comprehension was assessed in either the same (congruent) or the different (incongruent) medium. No significant differences in performance were found between the congruent and incongruent study-test conditions. However, consistent with findings reported in the literature, comprehension of the digital text was inferior to that of the printed text. Results show that this screen inferiority occurred irrespective of the testing medium. These findings suggest that studying in one medium and taking the test in another does not affect comprehension, but the medium in which one studies does influence test outcomes. 相似文献

INTUITEL is a research project aiming to offer a personalized learning environment. The INTUITEL approach includes an Intelligent Tutoring System that gives students recommendations and feedback about what the best learning path is for them according to their profile, learning progress, context and environmental influences. INTUITEL combines efficient pedagogical-based recommendations with freedom of choice and it introduces this tutoring support in different Learning Management Systems. During the INTUITEL project various software and pedagogical testing procedures were defined to provide the development teams with feedback, both summative and formative. The current paper describes the initial user test, which was conducted at the University of Valladolid for the course “Network Design”. The experiment was focused on real learners’ reactions to INTUITEL recommendations received by an INTUITEL-enabled LMS. Nineteen students participated in a two phase testing procedure in order to analyze the learners’ behavior with INTUITEL, as well as obtaining information about how learners perceive the influence and usefulness of the tutoring system in online learning courses. Results show that students with INTUITEL follow learning paths that are more suitable for them. Besides, the general satisfaction level of participants is high. Most learners appreciate INTUITEL, would follow its recommendations and consider the messages shown by INTUITEL as useful and caring. 相似文献

Performance support (PS) platforms, also known as electronic performance support systems (EPSS), offer real‐time learning and performance enhancement. In 2008, Tel Aviv University and an Israeli telecommunication firm began researching implementation success factors. Preliminary findings and conclusions were discussed in an earlier Performance Improvement article (Gal & Nachmias, 2011). The current article focuses on the effects of users' attitudes on implementation issues and suggests a model for incorporating EPSS in organizations. 相似文献
