Prospective gymnasium teachers' conceptions of chemistry learning and teaching

The aim of the study was to investigate prospective gymnasium teachers' conceptions of chemistry learning and teaching. Data were collected through individual interviews with nine prospective teachers at one German university. Phenomenography served as the methodological framework for the study. The findings revealed that chemistry learning is conceptualized as gaining knowledge, problem-solving and constructing personal understandings; and that chemistry teaching is conceptualized as transferring knowledge, problem-posing and interacting with pupils. The majority of the prospective teachers' conceptions of learning chemistry were considered reproductive rather than constructive and their conceptions of chemistry teaching were viewed as facilitating reproductive learning. Comparisons of the dominant conceptions of learning chemistry and teaching chemistry held by each prospective teacher revealed mixed support for the assumption that if one holds a reproductive (or constructive) conception of teaching, then (s)he will also hold a reproductive (or constructive) conception of learning. Support for the assumption was found in the reproductive-oriented relationship between conceptions of learning chemistry as gaining knowledge and of teaching chemistry as transferring knowledge, but not found in the relationships between learning chemistry as problem-solving and teaching chemistry as problem-posing and between learning chemistry as gaining knowledge and interacting with pupils.     

La Mesure des Effets Pédagogiques des TIC : Pièges et Illusions du Découpage du Réel et de L'administration de la Preuve

La forte incitation actuelle de la part des autorités scolaires À recourir aux médias numériques en classe pose une nouvelle fois la question des arguments mis en avant. Et comme À l'occasion d'incitations antérieures (télévision scolaire, audiovisuel, informatique éducative), partisans et détracteurs s'appuient sur différents travaux qui attestent ou non de telle ou telle amélioration ou dégradation. Cette contribution se propose de montrer que les concepts et les modèles convoqués dans certains travaux, y compris les nÔtres et notamment le programme IN-TELE (Internet-Based Teaching and Learning), établissent entre les situations d'enseignement-apprentissage considérés comme classiques et celles qui sont supposées innovantes des distinctions parfois non pertinentes, qui se traduisent par des résultats outrageusement significatifs ou non significatifs. C'est donc le schéma modèle-observation-interprétation que nous interrogeons en suggérant que les outils de pensée disponibles et les procédés d'observation mis en m uvre aujourd'hui dans les différentes disciplines académiques qui s'intéressent aux usages pédagogiques des TIC contraignent, voire altèrent, notre compréhension des phénomènes éducatifs induits par les 'nouveaux' médias. Measuring the pedagogic effects of CIT: traps and illusions of cutting out actuality, and the

administration of proof. The strong current encouragement of school authorities to have recourse to digital media in the classroom poses once again the question of the arguments that have been advanced. And, as at the tine of earlier encouragement, (for school television, audiovisual, educational informatics), partisans and detractors rely on different works which support, or not, such-and-such a praise or detraction. This contribution attempts to show that the concepts and the models brought together in certain works, including our own and notably the IN-TEL (Internet-Based Teaching and Learning) programme, which establish between the teaching-training situations considered as classic and those which are supposed to be innovative, distinctions which sometimes are not pertinent, which are translated into results which are outrageously significant – or non-significant. It is, then, the schema of model-observation-interpretation that we question in suggesting that the mental tools available and the observational procedures used today in the different academic disciplines which are interested in the pedagogic use of CIT constrain us to see, may even, alter our understanding of the educational phenomenon introduced by the 'new' media. Analyse der pädagogischen Auswirkungen von ICT (Information and Communcation Technologies) : Fallen und Illusionen aus der Wirklichkeit, sowie die Beweisführung. Die gegenwärtig stark geförderte Umstellung des Unterrichtsmaterials auf digitale Medien durch die Schulbehörden, stellt erneut die bereits vorgebrachten Argumente in Frage. Und wie schon bei vorangegangenen Einführungen (von Schulfernsehen, Audiovision, pädagogische Informatik) beziehen sich Befürworter und Gegner auf verschiedene Studien, die den Nutzen oder Unnutzen attestieren. Dieser Beitrag versucht aufzuzeigen, dass herangezogene Konzepte und Modelle in verschiedenen Arbeiten - einschliesslich der unseren und insbesondere des Programms IN-TELE (Internet-Based Teaching and Learning) - sich zwischen klassischen Bildungssituationen und denen als innovativ angenommenen wiederfinden - auch wenn diese Unterscheidung nicht immer treffend ist. Wir stellen also das Schema Modell-Observation-Interpretation in Frage, indem wir suggerieren, dass die heute applizierten Denkmodelle und Observationsverfahren - der verschiedenen akademischen Disziplinen, die sich für den pädagogischen Gebrauch von ICT interessieren - für unser Verständnis des pädagogischen Einflusses durch Multimedia hinderlich sind, ja wenn nicht sogar deren Gebrauch nachteilig beeinflussen.

Can self-report data on deficits in reading and spelling predict spelling disability as defined by psychometric tests?

Questionnaire data concerning spelling and reading self-assessment, habits, and school history were obtained for 79 adults (54 women and 25 men). The items were used to predict affectedness as defined on the basis of psychometric tests. For this purpose, two different discriminant analytical approaches (linear discriminant analysis and hierarchical classification with CART) were compared using a cross-validation design. 86.8–92.6% of the learning sample and 87.5–88% of the cross-validation sample were classified correctly. The CART model was preferred due to a balanced relation of sensitivity and specificity. Our results support the conclusion that self-report data are appropriate to substitute psychometric tests if these cannot be administered.     

Lifelong learning and second-order learning objects

Current cultural, social, and economic trends challenge traditional concepts of learning and lifelong learning. This paper draws on the twofold nature of learning in a knowledge society and explores options for technological support. The concept of Second‐Order Learning Objects is introduced as a potential means to foster generative learning. Generative learning goes beyond that what is already known and extends or transforms the socially shared knowledge including its artefacts and practices. According to the notion of individual and social learning as a process of reflective action, the role of strategies and media for reflection and inquiry is stressed. This paper outlines the use of schematically represented strategies for learning and reflection and sketches important features of a pursuant modelling approach.     

A Reconsideration of Cognitive Load Theory

Cognitive load theory has been very influential in educational psychology during the last decade in providing guidelines for instructional design. Whereas numerous empirical studies have used it as a theoretical framework, a closer analysis reveals some fundamental conceptual problems within the theory. Various generalizations of empirical findings become questionable because the theory allows different and contradicting possibilities to explain some empirical results. The article investigates these theoretical problems by analyzing the conceptual distinctions between different kinds of cognitive load. It emphasizes that reduction of cognitive load can sometimes impair learning rather than enhancing it. Cognitive load theory is reconsidered both from the perspective of Vygotski’s concept of the zone of proximal development and from the perspective of research on implicit learning. Task performance and learning are considered as related, but nevertheless fundamentally different processes. Conclusions are drawn for the further development of the theory as well as for empirical research and instructional practice.
