Although several studies have explored the attitudes of teachers and students towards CALL, there has been little research regarding students' insights and impressions. We agree with Kessler and Plakans (2001, p. 15) when they state that in the process of evaluating materials ‘learners must be included, as they are also experts of their learning as well as the benefactors of well‐developed materials’. With this in mind, we undertook a study in which students were given the opportunity to express their opinions about the software they used in the multimedia laboratory. The sample was made up of 59 undergraduates who completed a questionnaire. The conclusion to be drawn is that students clearly see software programs as a complementary tool in the foreign language classroom.Évaluation par les étudiants des programmes d'informatique. Bien que plusieurs études aient exploré les attitudes des enseignants et des enseignés envers le CALL, il y a eu peu de recherches sur les vues et impressions des étudiants. Nous sommes d'accord avec Kessler et Paklans (2001, p. 15) quand ils déclarent que dans le processus d'évaluation des documents les étudiants doivent être inclus car ils sont aussi experts de leur apprentissage aussi bien que les bénéficiaires de documents bien conçus! Dans cet esprit nous avons entrepris une étude dans laquelle les étudiants ont eu l'occasion d'exprimer leurs opinions sur le logiciel qu'ils utilisent dans le laboratoire multimédia. L'échantillon était constitué de 59 « undergraduates » qui ont rempli un questionnaire. La conclusion à en tirer est que les étudiants voient clairement ces logiciels comme un outil complémentaire dans la classe des langues étrangères.Evaluation von CALL Software Programmen durch Studenten. Obwohl verschiedene Studien die Einstellungen von Lehrern/Dozenten und Schülern/Studenten dem CALL-Programm gegenüber untersucht haben, ist bislang wenig über die Eindrücke und Erlebnisse der Schüler und Studenten geforscht worden. Wir stimmen mit Kessler und Plakans (2001, S 15) überein, wenn sie behaupten, dass man im Prozess der Evaluierung des Materials 'die Lerner einbeziehen sollte, da sie einerseits Experten ihres eigenen Lernprozesses sind und andererseits von gut entwickelten Materialien profitieren'. Dies berücksichtigend führten wir eine Studie durch, in der den Studenten die Gelegenheit gegeben wurde, ihre Meinungen über die Software, die sie im Multimedia-Labor nutzten, darzulegen. Die Stichprobe bestand aus 59 Studenten, die einen Fragebogen ausfüllten. Die Schlussfolgerung war, dass Studenten Softwareprogramme eindeutig als ergänzendes Werkzeug im Fremdsprachenunterricht betrachten. 相似文献

The approach of learning science through inquiry presents significant challenges for teachers and students. In light of this, an extensive experience has been developed in which students without any previous training or specific interests have been organized into small groups to carry out scientific inquiry projects guided by their teachers. Evaluation of the experience is clearly positive, and is based on questionnaires completed at the end of the experience by the students as well as retrospective reports provided by their teachers. Despite this, some problems are presented, such as the difficulty or repetitiveness of some scientific practices mentioned by some students, or when the inquiry or the group does not work out in some cases, as mentioned by teachers. Scientific inquiry projects like the one described here could play a key role in science education in compulsory secondary education. 相似文献

This paper examines the determination of wage rates for health professionals using three well known, and commonly used, econometric
techniques: ordinary least squares, instrumental variables, and Heckman’s method. The data come from a graduate survey and
the analysis focuses on a regional labor market, due to nationwide information on salaries is absent in Spain. After estimating
different wage equations, the results suggest that OLS estimates are preferable. The findings show an important wage premium
for medical doctors relative to nurses, but also a wage advantage for workers who are civil servants and a gender wage-gap
that favors men. Although the expansion of higher education in Spain has reduced social inequalities in access, the main policy
implication from this paper is that social class differences can still persist at the degree level—in the choice of degree—if
students of higher socioeconomic status get a place at university in a degree of higher earnings, a fact that is corroborated
in this study. 相似文献

This research analyzes the performance of 467 record labels in eight European countries over a period of 13 years (2003–2015). The main goal is to explain a relative measure of profitability in terms of observed variables, although the nature of the dataset also allows us to include non-observed firm and country effects. To this end alternative models are estimated and three main research questions are tested, namely: (1) the effect of the dual structure of the recorded music market, in which a competitive segment and an oligopoly coexist; (2) the extent and source of the volatility of profits in record labels; and (3) the nonlinear impact of size on performance. 相似文献

The purpose of this study was to determine the foot strike patterns (FSP), rearfoot position at initial contact (RPic, i.e., No INV/EVE) and foot rotation in children in relation to age. A total of 932 children aged 3 to 16 years participated in this study. A sagittal and frontal-plane video was recorded using a high-speed camcorder to analyse these variables. There is a significant increase (p < 0.001) of rearfoot strike patterns (RFS) prevalence in relation to age; e.g. preschool children (3–6 years old) displayed an RFS prevalence 46.65% and the adolescent population(15–16 years old) an RFS prevalence 92.20%. The total RFS prevalence in all samples was 69.25%. There was a significant reduction (p < 0.001) of prevalence of RPic in relation to age groups; preschool children displayed a prevalence of RPic 60.37% and the adolescent population 10%. There was a significant reduction (p < 0.001) of prevalence of no foot rotation in relation to age groups; preschool children displayed a prevalence of no foot rotation 48.95% and the adolescent population 13.55%. In conclusion, FSP in children are influenced by age. It is noteworthy that the RFS prevalence of children is lower in comparison to the adult population. 相似文献

This paper examines re-training transition processes as a basis for understanding adult learning and career change. The paper distinguishes between frame breaking and incremental change, describes learning methods associated with these levels of change, outlines phases of the transition process, and considers the relationships between degrees of change and likely coping styles during the transition phases. Variables reflecting career motivation and situational support are predicted to affect the transition process under different degrees of change. The concepts discussed here can be used as a basis for diagnosing situational conditions and individual characteristics to design more effective learning methods in organizations. 相似文献

The renaissance frescoes of the metropolitan cathedral of Valencia, located at the vault of the apse, were restored in 2006. We describe a microclimate monitoring system that was implemented for the preventive conservation of the paintings. It is comprised by a set of temperature and relative humidity sensors positioned at different points of the vault. This system is rather unique because some of these sensors were inserted inside the paintings during the restoration process. A principal components analysis was applied to the data of relative humidity recorded in February 2007. The analysis was repeated in three additional months of 2007. The resulting loading plots highlight the most relevant similarities and dissimilarities among sensors. These plots can be considered as some sort of control maps that could be used to detect abnormal conditions in the future. Actually, moisture problems at certain zones of the frescoes are causing the formation of efflorescence, and the sensors located close to these zones are the ones recording the highest values of relative humidity. 相似文献
