This research examined the impact of preservice teachers delivering individualized instruction of basic computer skills to at-risk, ethnic minority alternative high school students in an urban school district in South Texas. The alternative high school students' achievement of computer skills, motivation to use computers, and self-efficacy as current and future students was assessed. University preservice teachers taught a keyboard/computer skills curriculum developed specifically for this collaborative teaching and learning project in 10 1-hr-long sessions 2 times a week over a 5-week period. A series of 2 by 2 repeated measures analysis of variance showed achievement gains as measured by a survey instrument within the treatment group. This small, preliminary study supports the use of preservice teachers in the delivery of an individualized, computer-based program of instruction for at-risk students. 相似文献

Learning Networks (LNs) are online social networks designed to support nonformal learning; they are therefore particularly suitable for self-directed learners. In LNs, learners need to construct knowledge through knowledge sharing with other participants. However, without support, learners have to organize knowledge sharing themselves and this could induce extraneous cognitive load. When working on complex learning tasks, this organizing process could have a detrimental effect on knowledge construction. To optimize cognitive load, we propose using a peer support system that applies the mechanisms of peer tutoring to support knowledge sharing. Its mechanisms reduce, we argue, the extraneous load imposed by having to organize knowledge sharing as well as induce germane load by directing the freed-up cognitive capacity to processes that contribute to knowledge construction. 相似文献

This article reports on an experimentinvestigating the impact of causal discoursemarkers (connectives and signaling phrases) onthe comprehension of expository texts in L1 andL2. Although several psycholinguistic studieshave investigated the impact of connectives andlexical markers of text structure oncomprehension (i.e. off-line), there is noconsensus on the exact effect of explicitdiscourse markers on text understanding; threedifferent findings are reported in theliterature: markers would have a facilitatingeffect, an interfering effect or no effect atall. The first goal of this article is toclarify this problem of contradicting resultsby limiting the scope of the study to causalrelations, and to one specific text type:expository texts. Furthermore, the naturalnessof the experimental texts was controlled,readers did not need specific backgroundknowledge to understand the texts and theexperimental method consisted of open answerquestioning. Our second goal is to investigateto what extent a supposed effect of linguisticmarking depends on readers proficiency in afirst or second language.The experiment consisted in the reading of short expository texts in two languages, Dutchand French, which both functioned as L1 and L2.The results indicate that readers benefit fromthe presence of causal relational markers bothin L1 and in L2. Implications for (theoriesof) text processing are discussed, as well asfor the further insights in readingcomprehension in L1 and L2. 相似文献

Biosynthetic microspheres have the potential to address some of the limitations in cell microencapsulation; however, the generation of biosynthetic hydrogel microspheres has not been investigated or applied to cell encapsulation. Droplet microfluidics has the potential to produce more uniform microspheres under conditions compatible with cell encapsulation. Therefore, the aim of this study was to understand the effect of process parameters on biosynthetic microsphere formation, size, and morphology with a co-flow microfluidic method. Poly(vinyl alcohol) (PVA), a synthetic hydrogel and heparin, a glycosaminoglycan were chosen as the hydrogels for this study. A capillary-based microfluidic droplet generation device was used, and by varying the flow rates of both the polymer and oil phases, the viscosity of the continuous oil phase, and the interfacial surface tension, monodisperse spheres were produced from ∼200 to 800 μm. The size and morphology were unaffected by the addition of heparin. The modulus of spheres was 397 and 335 kPa for PVA and PVA/heparin, respectively, and this was not different from the bulk gel modulus (312 and 365 for PVA and PVA/heparin, respectively). Mammalian cells encapsulated in the spheres had over 90% viability after 24 h in both PVA and PVA/heparin microspheres. After 28 days, viability was still over 90% for PVA-heparin spheres and was significantly higher than in PVA only spheres. The use of biosynthetic hydrogels with microfluidic and UV polymerisation methods offers an improved approach to long-term cell encapsulation. 相似文献

Peace and conflict studies (PACS) education has grown significantly in the last 30 years, mainly in Higher Education. This article critically analyzes the ways in which this field might be subject to poststructural critique, and posits Bourdieusian second-order reflexivity as a means of responding to these critiques. We propose here that theory-building within PACS education is often limited by the dominance of Galtung and Freire, and that, while the foundational ideas of positive and negative peace, structural and cultural violence, conscientization, reflexivity and critical pedagogy are still relevant today, they nevertheless need to be combined in new ways with each other, and with Bourdieu’s notions of habitus and field, to adequately respond to poststructural critique. Thus, we call here for greater field-based reflexivity in twenty-first century PACS. 相似文献

Students’ vocational knowledge can be defined as all knowledge students require performing within occupational practice. In the context of vocational education and training, students’ vocational knowledge is often discussed from a perspective of either what should be taught and learned in schools or different kinds of knowledge students should gain in occupational practice. Much less focus is on students’ vocational knowledge itself. This exploratory in-depth study aims to describe what characterises students’ vocational knowledge. To explore students’ vocational knowledge, an analytic framework is used to describe vocational knowledge characteristics specifying: (1) occupation-specific knowledge components, and (2) qualities. Results show the framework provides a structure to gain insight into the nature and meaning of vocational knowledge, and is valuable to describe characteristics in terms of knowledge components such as technical procedures or the social and occupational environment, and qualities such as richness, complexity and specificity. Additionally, to use an existing framework – originally developed in the contexts of ICT and Social Work – its usefulness is explored in a new context, namely, the hospitality industry. Recommendations about the framework serving as a potential tool to support students’ learning processes are provided. 相似文献
