The quality of teaching and learning has been one of the major concerns of foundation chemistry disciplines for science and engineering undergraduates at the University of Aveiro, Portugal. Student‐centred approaches are being continuously developed, exploring ways of stimulating active and meaningful student learning by encouraging questioning by students. The development of questioning competences is regarded as fundamental, particularly in science education. In order to reinforce adequate alignment with teaching strategies, a new assessment method was implemented during the academic year of 2004–2005. This study is mainly aimed at exploring the use and integration of students’ questions as alternative assessment tools. Written formative and summative problem‐based cases were designed for these purposes. The questions raised by students during those assignments were analysed according to their cognitive level, relationship and orientation to the problem posed, herein considered to be quality indicators for learners’ questions. The findings suggest a deep engagement of students within these situations along the year, supporting the use of these alternative assessment tools as a way of fostering students’ questioning capability. Results also reveal that it is possible to achieve, with students’ questions placed at the centre of these processes, alignment between teaching, learning and assessment.  相似文献

Introduction

This issue of the feature column reports on developments in Peru on the use of information and communication technologies to improve public health. The authors describe how cell phones and hand‐held devices are being deployed to monitor diseases. Recent concerns about the spread of swine flu highlight the importance of robust public health systems in developing countries. 1 Jeannete Murphy

This article provides an analysis of Arizona’s policy response in educating English language learners by conducting a narrative review. A critical Latina/o theory approach was used to analyze the data. This study reveals 5 salient policy responses: (a) severely limit bilingual education, (b) develop controversial funding solutions, (c) implement a segregated 4-hr English language development block, (d) mandate structured English immersion–focused teacher preparation, and (e) develop disputed identification and classification instruments. The available data suggest that these policies have negatively impacted the educational experience and academic attainment of English language learners.  相似文献

The provision of workplace-based experiences (internships) is an important component of the training program for students attending vocational education courses. The purpose of this study was to clarify the relationship between internship quality and students vocational development, considering students’ vocational profiles, in a sample of 346 twelfth grade students from southern Portugal, using a longitudinal design. Results show that internship quality is associated with the career development of students, mainly concerning the process of career exploration, and has an effect that appears to be more pronounced for some of the clusters. Implications for career intervention are discussed.  相似文献

Students' metacognitive skills and perceptions are considered important variables for high-quality learning. In this study, students' perceptions were used to identify histological threshold concepts (integrative, irreversible, transformative, and troublesome) in three health sciences curricula. A specific questionnaire was developed and validated to characterize students' perceptions of histological threshold concepts. A sample of 410 undergraduate students enrolled in the dentistry, medicine, and pharmacy degree programs participated in the study. Concepts assessed in the study were clustered to ten categories (factors) by exploratory and confirmatory factor analysis. Concepts linked to tissue organization and tissue functional states received the highest scores from students in all degree programs, suggesting that the process of learning histology requires the integration of both static concepts related to the constituent elements of tissues and dynamic concepts such as stem cells as a tissue renewal substrate, or the euplasic, proplasic and retroplasic states of tissues. The complexity of integrating static and dynamic concepts may pose a challenging barrier to the comprehension of histology. In addition, several differences were detected among the students in different degree programs. Dentistry students more often perceived morphostructural concepts as threshold concepts, whereas medical students highlighted concepts related to two-dimensional microscopic identification. Lastly, pharmacy students identified concepts related to tissue general activity as critical for the comprehension and learning of histology. The identification of threshold concepts through students' perceptions is potentially useful to improve the teaching and learning process in health sciences curricula.  相似文献

Statistics teaching should not be carried out in the same way for all kinds of university students. Instead, teaching statistics should take into account the different fields of study that students have chosen. For example, students of sciences or engineering have different interests and backgrounds compared to students of any social or juridical field. The authors address this latter group of students (social, juridical, labor or even economics). The authors propose a direct approach: beginning with a real situation or supposition with real data. Questions of interest are explored and put into the language of statistics. To answer the questions, the necessary statistical methods are used. If needed, these methods are presented and explained at that time. Finally, the authors return to the beginning, to give an interpretation of the results. The approach takes into account the students' levels and the kind of studies or professional orientation of these students.  相似文献

Theimmediate shock deficit refers to the failure of a shock to become associated with contextual stimuli when the shock is presented simultaneously with the rat’s placement in a context. The basic procedure consists of a presentation of the shock as soon as the animal is placed in an observation chamber. Handling of the animal, which immediately precedes the shock, and the novelty of the chamber in which the immediate shock is delivered are potential variables that might be responsible for this associative deficit. In Experiment 1, handling reduced context conditioning but was not responsible for the immediate shock deficit. Experiment 2 revealed that the novelty of the chamber was not a significant factor. These results discount the possibility that handling and the novelty of the chamber are responsible for the deficit produced by the immediate shock. It is suggested that immediate shock could be employed as a control procedure for the study of context conditioning.  相似文献

Linguists generally conceive of speech as a sequence of elementary soundunits or phones. On the other hand, cognitive psychologists have established the existence of a close link between segmental awareness (SA) and alphabetic literacy: the best speech segmenters are also the best readers; conversely, the lack of SA leads to lagging in the acquisition of the written code. Studies carried out with illiterate adults and preliterate children suggest that SA does not arise outside the context of learning to read and write. Furthermore, cross-cultural studies have so far supported the hypothesis that SA is promoted by alphabetic literacy only, and not by logographic or syllabic literacy. The present study is inspired by Mann's (1986) research and aims at studying the phonological (i.e. syllabic and phonemic) analysis abilities of Japanese first-graders who are learning to read in a syllabic writing system. The relatively poor performance of subjects tends to confirm the starting hypothesis that SA is closely linked to alphabetic literacy. Moreover, the subjects apparently resorted to spelling-based strategies to accomplish the tasks presented. This comes to support the general idea that the written characters used to transcribe a language tend to exert a strong influence on the conscious perceptual representation of the phonology of this language.This study would not have been possible without the precious help of Miss T. Yamamoto for the construction of the experimental items. We are also much indebted to Mrs. A. M. Van Craen for her good advice and for having introduced one of us (Carmela Spagnoletti) to the Japanese School of Brussels. We also wish to thank the Director of the Japanese School of Brussels for his permission to carry out the experimental work with his pupils, and to all the professors for having invited the parents to cooperate and provided us with many useful information. We are especially grateful to the children who participated to the experinmental sessions as well as to their parents. The present work has been partially supported by the Belgian Fonds de la Recherche fondamentale collective (convention n° 2.4562.86) and the Ministry of scientific Policy (Action de Recherche concertée: Processus cognitifs dans la lecture).  相似文献
