This paper presents a qualitative case analysis of a new and unique, high school, student-directed, project-based learning (PBL), virtual reality (VR) class. In order to create projects, students learned, on an independent basis, how to program an industrial-level VR machine. A constraint was that students were required to produce at least one educational application of VR. This study incorporated in-depth classroom observations, interviews with students, analyses of student projects, and surveys of parents and teachers to examine the social and learning processes in the class, and the nature of content learning represented in student projects. The results demonstrated that PBL can be effective even with minimal teacher guidance. The findings substantiate an educational approach rich with promise, for at least some students, that deserves considerable additional study to maximize its powerful potentials for independent and peer-mentored learning. 相似文献

To know whether students' achievements are the result of online interaction and not just a consequence of individual differences themselves, it seems essential to link the cognitive results to the students' online behavior (technological presence). In technological presence, interaction is based on the degree in which the online student senses the availability of, and connectedness with, other students, the teacher, and the context. Cognitive presence as a part of the interaction process of teaching and learning reflects the level of accomplishment in online learning environments (cognitive attainment). The purpose of this article is to show some evidence of the mutual influence of the students' technological behaviors and the students' cognitive factors in online learning environments – including teacher and instructional design factors. Two thousand one-hundred thirty written computer-mediated communications from 88 participants in four prototypical online learning activities have been analyzed for this purpose. The analysis shows the influence of technological presence on the quality of learning results of the online knowledge construction process. The conclusions point out the importance of considering technological presence as a new and complementary type of presence as it provides relevant information for instructional and technological design. 相似文献

We describe the results of electromigration desalination of two soluble salt-contaminated Galician granites. The efficacy of electromigration, which had not been previously applied to granite, was assessed for two types of granite contaminated with a 20% NaCl solution and seawater. Desalination effectiveness was evaluated as follows: (1) analysis of anode and cathode ion content during testing; (2) analysis of ions at different distances from the electrodes after testing; (3) pH assessment of the stone surfaces; and (4) evaluation of colour changes. Results were very satisfactory; by the end of testing, chloride was reduced by almost 100% in both the NaCl and seawater contaminated samples. Sulfate reduction was also significant, despite this ion's lower mobility. The granite pH values remained close to neutral and colour changes were minimal. The difference in effectiveness of the process for the two types of stone was associated with their dissimilar pore structure. 相似文献

ABSTRACT Game developers potentially convey socio-cultural values about gender through design choices. This study interpreted the designs of 11 purposively selected female game characters, developed by studios located in the United States and Japan, through the lens of ambivalent sexism. This social psychological theory posits that sexism consists of hostile and benevolent attitudes about women. Two themes emerged across characterizations: bodies as objects, bodies as weapons and (in)dependence. Both consisted of empowering qualities paired with problematic beliefs about women. This analysis contributes to interdisciplinary literature by using an empirical perspective to interpret gender representations in video games. 相似文献

AbstractThis study examined a project that delivered social work services to homeless individuals. A mixed-methods case study was conducted using quantitative and qualitative data from 93 library employees and the project’s Homelessness Prevention Outreach Worker (HPOW). There was an increase in the number of clients accessing community supports during the project, and the HPOW was integral to the provision of support and resources to homeless individuals. Staff training was associated with significantly greater knowledge, comfort, and skills in working with homeless individuals. These findings can inform the delivery and implementation of similar programs for homeless individuals. 相似文献

Need for closure, as formulated by Kruglanski and colleagues [Kruglanski, A. W. (1990). Lay epistemic theory in social-cognitive psychology. Psychological Inquiry, 1(3), 181–197; Kruglanski, A. W., & Webster, D. M. (1996). Motivated closing of the mind: Seizing and freezing. Psychological Review, 103, 263–283; Webster, D. M., & Kruglanski, A. W. (1994). Individual differences in need for cognitive closure. Journal of Personality and Social Psychology, 76(6), 1049–1062], refers to the motivated tendency to seek structure, simplify complex information, and avoid ambiguity. In this article, we argue that this motive may impact classroom learning in important ways and introduce a self-report measure of need for closure situated in the classroom learning environment. Psychometric properties of the new measure are assessed in multiple samples using exploratory and confirmatory factor analysis. Correlations between the new measure and existing indicators of cognitive closure, as well as variables known to influence motivation and academic achievement, support our assertions regarding the association between need for closure and academic functioning while also providing evidence for the construct validity of the measure. Finally, internal consistency and test–retest reliability suggest that the new measure functions as a reliable measure of need for closure within the classroom. 相似文献

Drawing on research that sought to explore the characteristics of ‘Possibility Thinking’ as central to creativity in young children's learning, this paper considers question‐posing and question‐responding as the driving features of ‘Possibility Thinking’ (PT). This qualitative study employed micro‐event analysis of peer and pupil–teacher interaction. Events were sampled from two early years settings in England, one a Reception classroom (4‐ to 5‐year olds) and the other a Year 2 classroom (6‐ to 7‐year olds). This article arises out of the second stage of an ongoing research programme (2004–2007) involving the children and practitioners in these settings. This phase considers the dimensions of question‐posing and the categories of question‐responding and their interrelationship within PT. Three dimensions of questioning were identified as characteristic of PT. These included: (i) question framing, reflecting the purpose inherent within questions for adults and children (including leading, service and follow‐through questions); (ii) question degree: manifestation of the degree of possibility inherent in children's questions (including possibility narrow, possibility moderate, possibility broad); (iii) question modality, manifestation of the modality inherent in children's questions (including verbal and non‐verbal forms). The fine‐grained data analysis offers insight into how children engage in PT to meet specific needs in responding to creative tasks and activities and reveals the crucial role that question‐posing and question‐responding play in creative learning. It also provides more detail about the nature of young children's thinking, made visible through question‐posing and responding in engaging playful contexts. 相似文献
