In cooperative learning, students work together as a team to maximize the academic success of all the team members. The failure of even a single member can compromise the success of the entire team. Thus, to evaluate the functioning of the team reliably, it is necessary to consider both the performance of the individual team members and the interactions among them. In this study, a method was developed for identifying dysfunctional teams and troubled individuals by examining the correlation between the team scores obtained in sequential tests and the correlation between the scores obtained by the different team members. The effectiveness of the proposed method was evaluated via field experiments. Forty‐eight students were randomly assigned to cooperative learning teams and their learning performance assessed by four‐unit tests. The results indicated that the proposed method can identify the most troubled individuals in a team even when the team performance/grouping information is not taken explicitly into account. Furthermore, when the team information is considered, the method can identify both the dysfunctional teams and the troubled individuals within the teams. Therefore, the proposed method provides a useful basis for the development of computer‐assisted solutions for assessing the performance of cooperative learning teams.  相似文献

Advances in our knowledge of the structure of working memory suggest that under some circumstances, effectively more processing capacity is available to learners if instructional materials use multiple information modes (e.g. auditory and visual) instead of equivalent single mode formats. This paper examined this modality effect from a cognitive load perspective in three experiments using geometry instruction. In accordance with cognitive load theory, it was predicted that the additional processing capacity provided in an audio/visual format would only enhance learning if mental resources were not devoted to extensive visual based search in order to coordinate auditory and visual information. Using two different areas of geometry, Experiments 1 and 2 found that if visual search was clearly high, then audio‐visual instruction was only beneficial if visual indicators in the form of electronic flashing were incorporated into the instructional format. Under high search conditions, a standard audio/visual format without the aid of flashing proved no better than visual only instruction. Experiment 3 attempted to clarify earlier results by using instructional materials trivially low in visual search. Data indicated that a standard, audio‐visual format resulted in superior learning to a visual only format. There was no beneficial effect of electronic flashing in Experiment 3, suggesting that visual indicators were not necessary in areas of low visual search. It was concluded that cognitive load as determined by visual search established the effectiveness of visual indicators.  相似文献

The performance of a group of third‐year higher diploma students from the Department of Hotel & Tourism in a simulation training exercise was assessed separately by the tutor and peer group, using an identical checklist. Ninety‐six pairs of tutor and peer group assessment marks were obtained and compared. Results showed that there was some degree of agreement between tutor and peer group markings, although the level of congruence was somewhat less than reported in earlier studies. However, when the tutor and peer group average marks were converted to grades, agreement was found in only 46.9% of the cases and the level of agreement between the two gradings was not statistically significant. Significant differences were also found in the variability of tutor and peer group markings. Furthermore, there were indications that peer group markings tended to be more stringent than tutor markings in the higher mark range, but relatively more lenient in the lower mark range. This trend was particularly obvious when the tutor and peer group marks were converted into grades. Implications of the findings are also discussed.  相似文献

This study investigated how two readers of Mandarin with differing reading‐proficiency skills interacted with a narrative passage, as well as what knowledge they brought to and made use of while reading the text. The perspectives of reading comprehension, transactional theory and social‐cognitive models of reading served as this study's theoretical framework. Two Sixth‐Grade participants were selected for inclusion through snowball sampling. The data in this study were obtained from interviews and think‐alouds. Qualitative analysis indicated that the skilled Mandarin reader's stance moved along the efferent/aesthetic continuum, while the less‐skilled Mandarin reader's was mainly efferent. The skilled reader employed strategies of inferencing, summarisation and synthesis during and after reading, while the less‐skilled reader applied bridging inferences, paraphrasing and repetition. The findings of this study corroborate previous findings that proficient readers employ more sophisticated approaches to reading than less‐proficient readers.  相似文献

The study examined the predictive value of adolescents’ personality trait ratings by different groups of informants in explaining academic achievement [grade point average (GPA)] while controlling for students’ sex and their mothers’ education. The Inventory of Child/Adolescent Individual Differences was employed as a measure of students’ personality traits at the end of elementary schooling (mean age = 14.7 years) and two years later when the participants attended secondary schools. The trait ratings were obtained through self‐, maternal and peer reports at both measurement occasions. They explained substantial portions of unique variance in the students’ GPA concurrently, and over time. Ratings by each of the three groups of informants had an incremental validity over one another in predicting school grades. Among personality variables, conscientiousness and low extraversion were consistently predictive of GPA.  相似文献

This paper sets out to problematise generational categories such as “Power Users” or “New Millennium Learners” by discussing these in the light of recent research on youth and information and communication technology. We then suggest analytic and conceptual pathways to engage in more critical and empirically founded studies of young people’s learning in technology and media‐rich settings. Based on a study of a group of young “Power Users”, it is argued that conceptualising and analysing learning as a process of patchworking can enhance our knowledge of young people’s learning in such settings. We argue that the analytical approach gives us ways of critically investigating young people’s learning in technology and media‐rich settings, and study if these are processes of critical, reflexive enquiry where resources are creatively re‐appropriated. With departure in an analytical example, the paper presents the proposed metaphor of understanding learning as a process of patchworking and discusses how we might use this to understand young people’s learning with digital media.

Les “Power Users” et la construction en “patchwork” – Une approche analytique des études critiques portant sur l’apprentissage chez les jeunes avec l’aide des médias numériques.

Le présent article vise à faire ressortir la problématique des catégories de générations, celles par exemple des “Power Users” ou des “Apprenants du Nouveau Millénaire” en les examinant de façon critique à la lumière des recherches récentes sur la jeunesse et les TICE. Nous suggérons ensuite des voies d’approche analytiques et conceptuelles pour nous engager dans des études plus critiques et plus solidement empiriques de l’apprentissage chez les jeunes dans des environnements à fort contenu technologique et médiatique. En nous appuyant sur l’étude d’un groupe de jeunes “Power Users”, on avance l’hypothèse selon laquelle le fait d’analyser et de conceptualiser l’apprentissage comme un processus de construction de patchwork peut améliorer notre connaissance de l’apprentissage chez les jeunes se trouvant dans de tels environnements. Nous avançons l’idée que cette approche analytique nous fournit les moyens d’étudier de façon critique l’apprentissage chez les jeunes se trouvant dans des environnements à fort contenu technologique et médiatique et de déterminer s’il s’agit là de processus de recherche critique et réflexive dans lequel ils se réapproprient les ressources de façon créative. En s’appuyant sur un exemple analytique, cet article présente une proposition, celle d’une métaphore pour comprendre l’apprentissage comme un processus de patchwork et discute de la façon dont nous pourrions l’ utiliser pour comprendre de quelle façon les jeunes apprennent avec les medias numériques.

?Power User“ und ?Patchworking“ – eine analytische Annäherung an kritische Studien über das Lernen junger Leute mit digitalen Medien

Dieser Artikel problematisiert generationspezifische Kategorien wie ?Power Users“ und ?New Millenium Learners“ welche hier vor dem Hintergrund der jüngsten Forschungsergebnisse im Bereich Jugend und Informations‐ und Telekommunikationstechnologie (ITK) diskutiert werden. Darauf aufbauend werden analytische und konzeptionelle Wege vorgeschlagen, wie auf empierischer und auf Fakten basierender Grundlage das Lernen junger Menschen in einem technologie‐ und medienreichen Umfeld studiert werden kann. Eine Gruppe junger ?Power Users“ ist die Grundlage unserer Argumentation, dass Konzeptionalisierung und Analyse des Patchwork Lernprozesses junger Leute unser Verständnis von ihrer Herangehensweise an den Lernprozess verbessern kann. Wir argumentieren, dass die analytische Herangehensweise uns hilft, das Lernen junger Leute im ITK Kontext zu analysieren und wir untersuchen, ob diese Prozesse kritisch und reflexiv sind und dazu beitragen, Ressourcen kreativ zu nutzen. Der Artikel schließt mit einem analytischen Beispiel in dem wir die zuvor diskutierte Metapher – Lernen als einen Patchworkprozess zu verstehen – nutzen, um zu diskutieren wie dieses Verständnis genutzt werden kann, um unser Wissen über das Lernen junger Leute mit digitalen Medien zu erweitern.

Los “Power Users” y la construcción en “patchwork” – Un enfoque analítico sobre los estudios críticos acerca del aprendizaje de los jóvenes con los medios digitales.

El propósito del presente artículo es de hacer resaltar la problemática de las categorías de generaciones, entre ellas los “Power Users” o los “discentes del Nuevo Milenio”, a través de una discusión de esas categorías a la luz de las últimas investigaciones sobre la juventud y las TICs. Sugerimos después algunos caminos analíticos y conceptuales para meterse en estudios con una base más crítica y más fuertemente empírica, del aprendizaje de los jóvenes en entornos con una fuerte dimensión tecnológica y mediatizada. Basandose en el estudio de un grupo de jovenes “Power Users”, se argumenta que el hecho de analizar y conceptualizar el aprendizaje como si fuese un proceso de “patchworking”, puede en realidad realzar nuestro conocimiento de la manera de aprender de los jovenes en entornos de ese tipo. Argumentamos que el enfoque analítico nos ofrece maneras de investigar críticamente el aprendizaje de los jóvenes dentro de entornos fuertemente tecnológicos y mediatizados y de estudiar si se trata de procesos de investigación crítica y reflexiva en los cuales se produce una re‐apropiación creativa de los recursos. Con una salida hacia un ejemplo analítico este artículo presenta la propuesta de una metáfora para entender el aprendizaje como si fuese un proceso de construcción de un “patchwork” con una discusión sobre las posibilidades de uso de esto para entender como los jóvenes aprender con los medios digitales.  相似文献

In this paper, we examine the nature and extent of participation of Canadian young women and men in science‐based academic fields. Informed by Bourdieu’s theory of cultural reproduction, we focus on three key stages—senior secondary school, the transition to post‐secondary studies, and the post‐secondary completion stage—to determine whether and how the interrelationships of gender, cultural capital, course completion in senior secondary school, timing of decisions, and initial participation in post‐secondary education lead to the completion of science‐related undergraduate degrees. Through correspondence analyses of 10 years of longitudinal data with 1,055 respondents, we extend the findings of cross‐sectional studies that examine only one aspect of this longitudinal story by showing how the intersection between organisational structures (institutional and disciplinary) and cultural capital transmitted by the family shapes the opportunity structures of access to scientific fields of study by young women and men.  相似文献

ABSTRACT

Community advisory boards (CABs) have been used to improve research outcomes involving specific communities and populations, including older adults. There is potential to synergize the use of CABs to encompass both research activities and the education of healthcare professionals to help meet increasing demands for a geriatric healthcare workforce in aging populations worldwide. We describe the development and process outcomes of a CAB that synergizes geriatric research and education of students in an allied health profession (occupational therapy). Implementation costs from June 2017–June 2019 were recorded. In-depth interviews were conducted with CAB participants, who were community-dwelling older adults living in St. Louis, Missouri, United States. Interview data were analyzed using a constant comparison method based on a grounded theory approach. Themes were derived regarding barriers, facilitators, and benefits of CAB participation for older adults. Fourteen older adults (aged 65 and over) were initially recruited. The total direct cost of CAB implementation was 4050 United States Dollars over two years. Barriers to CAB participation for older adults included unexpected schedule conflicts due to illness and lack of understanding of the research process, while facilitators included accessible meeting spaces, staff support, flexible participation options, and financial support (e.g., transportation). Perceived benefits of CAB participation included gains in social capital, more positive views of research, and social connectedness. Key lessons learned are described and can be used to inform a novel approach to developing and implementing CABs to improve outcomes of geriatric research and education.  相似文献

Suicidal and help‐seeking behaviors of students of color remain a significant problem on college campuses. Self‐reported suicidal experiences and help‐seeking behavior of diverse students are examined on the basis of results from a national survey of college student mental health. The results suggest significant differences in the expression of suicidal thoughts and behavior across racial and ethnic groups and different experiences in their referral for, and utilization of, professional help.  相似文献

This study (a) assessed the influence of three history of science (HOS) courses on college students' and preservice science teachers' conceptions of nature of science (NOS), (b) examined whether participants who entered the investigated courses with a conceptual framework consistent with contemporary NOS views achieved more elaborate NOS understandings, and (c) explored the aspects of the participant HOS courses that rendered them more “effective” in influencing students' views. Participants were 166 undergraduate and graduate students and 15 preservice secondary science teachers. An open‐ended questionnaire in conjunction with individual interviews, was used to assess participants' pre‐ and postinstruction NOS views. Almost all participants held inadequate views of several NOS aspects at the outset of the study. Very few and limited changes in participants' views were evident at the conclusion of the courses. Change was evident in the views of relatively more participants, especially preservice science teachers, who entered the HOS courses with frameworks that were somewhat consistent with current NOS views. Moreover, explicitly addressing certain NOS aspects rendered the HOS courses relatively more effective in enhancing participants' NOS views. The results of this study do not lend empirical support to the intuitively appealing assumption held by many science educators that coursework in HOS will necessarily enhance students' and preservice science teachers' NOS views. However, explicitly addressing specific NOS aspects might enhance the effectiveness of HOS courses in this regard. Moreover, the study suggests that exposing preservice science teachers to explicit NOS instruction in science methods courses prior to their enrollment in HOS courses might increase the likelihood that their NOS views will be changed or enriched as a result of their experiences with HOS. © 2000 John Wiley & Sons, Inc.
