The Relationship of the World Wide Web to Thinking Skills

As access to the WWW increases in schools and classrooms it is vital for educators at all levels to examine closely its potential roles in learning. Much emphasis has been placed upon making the WWW available without enough emphasis on methods of using it so students will benefit from instruction based upon it. A continuing goal of modern pedagogy is to help students move beyond the lower order cognitive domain, knowledge and comprehension, to higher order thinking skills: application; analysis;, synthesis; and evaluation. Students also need critical thinking skills. These skills are necessary for dealing with the demands of the future information society, which will be even more complex and demanding than at present. In order to foster the skills mentioned above, teachers are urged to provide learning environments that are learner-centred, authentic, problem-based and collaborative. Les relations entre le World Wide Web et les aptitudes des pensées. Comme l'accès au WWW s'accroît dans les écoles et les classes il est vital que les enseignants À tous niveaux examinent de près son rÔle potentiel en éducation. On a mis beaucoup l'accent sur les possibilités d'accès au WWW sans mettre assez l'accent sur les méthodes d'emploi par les étudiants de facon À ce qu'ils puissent bénéficier de l'instruction qu'il permet. Un objectif constant de la pédagogie moderne est d'aider les étudiants À dépasser le domaine cognitif limité. le savoir et la compréhension vers des aptitudes de pensée d'un ordre supérieur : applications, analyses, synthèses et évaluations. Les étudiants ont aussi besoin de pensée critique - ces aptitudes sont nécessaires pour faire face aux demandes de la future société de l'information, qui sera encore plus complexe et exigeante que maintenant. De facon À favoriser les aptitudes mentionnées ci-dessus , il faut que les enseignants fournissent les environnements éducatifs qui sont centrés sur l'apprenant, authentiques, basés sur la résolution de problèmes et la collaboration. Der Zusammenhang zwischen dem World Wide Web und den Denkfähigkeiten. Mit den wachsenden Zugängen an das WWW in Schulen und Klassenräumen wird es für Lehrer auf allen Ebenen immer dringender ihre zukünftige Rolle im Unterricht zu überdenken. Es wurde sehr viel Wert auf die Verfügbarkeit des WWWs gelegt, ohne jedoch auf Anwendungsmöglichkeiten zu achten damit die Lernenden von einem auf dem Web basierenden Unterricht profitieren. Ständiges Ziel moderner Pädagogik ist, Studenten zu helfen, über die untere Stufe des kognitiven Bereichs, Wissen und Verständnis, auf eine höhere Stufe des Denkprozesses zu gelangen: nämlich Anwendung, Analyse, Synthese und Bewertung. Schüler brauchen auch kritisches Denken. Diese Fähigkeiten sind notwendig im Umgang mit den Anforderungen der zukünftigen Informationsgesellschaft, die noch komplexer und schwieriger als die jetzige sein wird. Um diese Fähigkeiten zu fördern müssen Lehrer Lernumfelder schaffen, die sich am Studenten orientieren, authentisch sind, auf Problemlösungen basieren und collaborativ sind.     

Go your own way: lifelong learning and reflexive autobiographies in postmodernity

This article provides an autobiographical account of two adult educators engaged in what may be seen as an identity crisis for contemporary adult education. Through our autobiographical analysis, we address the question of what it means to be an adult educator or to practice adult education in circumstances where dedifferentiation has taken hold under the sign of lifelong learning. First, we outline the challenges that are taking place to many of the practices and institutional structures of adult education. At the heart of these, we argue that there is an intensification of reflexivity wherein the identity crisis with which we are working is both a condition for and a response to increasing individualization and reflexivity. Second, we illustrate the link between reflexivity and identity by drawing on our own autobiographies. Here we exemplify the processes we argue to be operating under the sign of lifelong learning through the exploration of our own autobiographical bricolages. Third, we explore the cultural conditions which give rise to the similarities and differences in these bricolages, in particular the rise of the new middle classes, the increased significance of popular culture and the development of postmodern positions.     

Pathways to STEMM Professions for Students From Noncollege Homes

In this article we use data from the Longitudinal Study of American Youth to examine the influence of parent education on pathways to science, technology, engineering, mathematics, and medicine (STEMM) professions. Building on a general model of factors related to STEMM education and employment, we employ a two-group structural equation model to examine the factors that predict enrollment in a postsecondary STEMM program and employment as a STEMM professional. The results of this analysis indicate that most of the variables in the two models function in a similar manner, but the levels of parental encouragement, help, and direction vary significantly between college-educated and non-college-educated families. The children of non-college-educated parents were less likely to take algebra in Grade 8, take calculus in high school, and take calculus in college than were the children of college-educated parents. Young adults that grew up in noncollege families were less likely to enter postsecondary education; more likely to begin postsecondary education at a community college; less likely to earn a baccalaureate, graduate, or professional degree; and less likely to become a STEMM professional. The analysis reveals a clear pattern of cumulative advantage and cumulative disadvantage, and the final section of this article discusses the need for educational and public policy leaders to develop strategies and programs to address the substantial differential associated with parent education.     

Implementation Factors and Their Influence on Student Mathematics Outcomes

Assessing implementation allows for a better understanding of an intervention's effects and the mechanisms that influence its impact. Two main areas of implementation are (a) the quality with which an intervention is delivered and (b) instructors’ adherence to the programmed intervention. The current study used data from a kindergarten mathematics intervention program to (a) examine if and how treatment adherence was associated with implementation quality and (b) explore implementation measures’ relation to student mathematics outcomes. Results indicated high implementation scores across time for both adherence and quality. Neither treatment adherence nor implementation quality was found to relate to a general outcome measure of student mathematics achievement; however, both were similarly related to the curricular-aligned measure.     

A latent profile analysis of college students’ achievement goal orientation

Achievement goal research has grown increasingly complex with the number of proposed goal orientations that motivate students. As the number of proposed goal constructs proliferates, a variety of data analytic challenges have emerged, such as profiling students on different types of goal pursuit as well as evaluating the relationships of multiple goal pursuit with different educational outcomes. The purpose of the current article is to showcase the advantages of using latent profile analysis (LPA) over other traditional techniques (such as multiple regression and cluster analysis) when analyzing multidimensional data like achievement goals. Specifically, we review the advantages of LPA over traditional person- and variable-centered analyses and then provide a critical look at three different conceptualizations of goal orientation (2-, 3-, and 4-factor) using LPA.     

An overview of 45 published database resources for complementary and alternative medicine

Background: Complementary and alternative medicine (CAM) has succeeded to implement itself in the academic context of universities. In order to get information on CAM, clinicians, researchers and healthcare professionals as well as the lay public are increasingly turning to online portals and databases, which disseminate relevant resources. One specific type of online information retrieval systems, namely the database, is being reviewed in this article. Question: This overview aims at systematically retrieving and describing all databases covering the field of CAM. One of the requirements for inclusion was that the database would also have to be published in a medical journal. Data sources: The databases amed , CAMbase , embase , and medline /Pub Med were searched between December 2008 and December 2009 for publications relevant to CAM databases. The authors’ specialist library was also searched for grey literature to be included. Study selection: All included databases were then visited online and information on the context, structure and volume of the database was extracted. Main results: Forty‐five databases were included in this overview. Databases covered herbal therapies (n = 11), traditional Chinese medicine (n = 9) and some dealt with a vast number of CAM modalities (n = 9), amongst others. The amount of time the databases had been in existence ranged from 4 to 53 years. Countries of origin included the USA (n = 14), UK (n = 7) and Germany (n = 6), amongst others. The main language in 42 of 45 databases was English. Conclusions: Although this overview is quite comprehensive with respect to the field of CAM, certain CAM practices such as chiropractic, massage, reflexology, meditation or yoga may not have been covered adequately. A more detailed assessment of the quality of the included databases might give additional insights into the listed resources. The creation of a personalised meta‐search engine is suggested, towards which this overview could be seen as a first step.     

The importance of socio-cultural context for understanding students’ meaning making in the study of genetics

In this rejoinder to Ann Kindfield and Grady Venville’s comments on our article “Reconsidering conceptual change from a socio-cultural perspective: Analyzing students’ meaning making in genetics in collaborative learning activities,” we elaborate on some of the critical issues they raise. Their comments make apparent some of the crucial differences between a socio-cultural and a socio-cognitive approach towards conceptual change. We have selected some issues that are addressed, either implicitly or explicitly, in their comments. The main issues discussed are talk and interaction as data, the significance of context in interaction studies, the feasibility of generic claims in small-scale interaction studies, and the difference between studying students’ understanding of science concepts as opposed to studying the construction of meaning.

Vimentin networks at tunable ion-concentration in microfluidic drops

The structure and function of biological systems, for example, cells and proteins, depend strongly on their chemical environment. To investigate such dependence, we design a polydimethylsiloxane-based microfluidic device to encapsulate biological systems in picoliter-sized drops. The content of each individual drop is tuned in a defined manner. As a key feature of our method, the individual chemical composition is determined and related to the drop content. In our case, the drop content is imaged using microscopy methods, while the drops are immobilized to allow for long-time studies. As an application of our device, we study the influence of divalent ions on vimentin intermediate filament networks in a quantitative way by tuning the magnesium concentration from drop to drop. This way we are able to directly image the effect of magnesium on the fluorescently tagged protein in a few hundreds of drops. Our study shows that with increasing magnesium concentration in the drops, the compaction of the networks becomes more pronounced. The degree of compaction is characterized by different morphologies; freely fluctuating networks are observed at comparatively low magnesium concentrations of 5–10 mM, while with increasing magnesium concentration reaching 16 mM they develop into fully aggregated networks. Our approach demonstrates how a systematic study of interactions in biological systems can benefit from the exceptional controllability of microfluidic methods.
