As technology becomes more accessible and acceptable in the preschool setting, teachers need effective strategies of incorporating it to address challenging behaviors. A nonconcurrent delayed multiple baseline design in combination with an alternating treatment design was utilized to investigate the effects of using iPad tablets to display video self‐modeling and activity photos for three preschoolers during circle time. During baseline, all three children demonstrated low levels of engagement and high levels of off‐task behavior compared to peers. The intervention phase consisted of alternating between showing the child the self‐video and photos prior to circle time. A child preference phase was conducted whereby each child self‐selected the video or photo prior to circle time. For all three children both videos and photos led to increased engagement and decreased off‐task behaviors. During the child preference phase, all three children selected the video most frequently. Social validity data demonstrated teacher and child preference for the video self‐modeling condition. 相似文献

Higher education and K-12 school partnerships are typically designed with an end-goal that serves the instructional needs of one group over the other. For this project, a university professor and elementary school instructor used problem-based and project-based learning strategies to design a curriculum that served the academic needs of both groups of students. Undergraduate students in an urban planning course partnered with elementary students from a local school to work on an interdependent civic engagement project. The partnership provided innovative, twenty-first teaching for both groups of students while also reinforcing public service. 相似文献

This study focuses on high school students’ profile choices and the choice for or against the Nature and Technology (NT) profile in the Netherlands. A mixed-methods approach is used to study cultural values that affect this choice. The quantitative part of the study shows that being female is negatively correlated with the choice for the NT-profile, irrespective of the grade average for mathematics, chemistry and physics. It further shows that students’ ethnic background does not have a significant effect on this choice. The qualitative part of the study reveals that students’ choice processes towards or away from NT can be categorised in three ideal types: the postmodern perfectionist, the pragmatic hedonist and the materialist maximalist. Gender differences appear to be more pervasive across these types than differences in ethnic background. 相似文献

Research Findings: The present cross-sectional study investigated the question of whether 6 different temperament dimensions (inhibition to novelty, social orientation, motor activity, positive emotionality, negative emotionality, and attention) influenced cognitive and affective theory of mind (ToM) in 168 children (86 three/four-year-olds and 82 four/five-year-olds). Temperament was measured via a parent-report questionnaire, cognitive ToM via a classical false-belief task, and affective ToM via a comprehensive test tapping 3 levels of emotion comprehension (external, mental, and reflexive). In addition, language competence was assessed with a direct test evaluating both receptive and expressive language. The results showed that after we controlled for language ability, inhibition to novelty predicted higher levels of cognitive ToM in 4/5-year-old children. In addition, higher levels of social orientation predicted better comprehension of the external aspects of emotion in both younger and older children. Practice or Policy: Our results highlight the importance of the early identification of less sociable children, who might benefit from training interventions aimed at increasing their affective ToM abilities. At the same time, they are also consistent with previous evidence indicating that an inhibited approach to social interaction can promote false-belief understanding. 相似文献

We describe the propagation of a technology-based educational innovation through its first 3 years of public use. The innovation studied is the Concept Warehouse (CW), a database-driven website developed to support the use of concept-based pedagogies. This tool was initially developed for instructors in undergraduate chemical engineering courses, but has spread to other disciplines as well. In this time, it has grown to over 650 registered instructors representing over 170 institutions. While this study is specific to a particular case, the intent of this article is to provide an exemplar of real-time propagation that informs other researchers and developers. We frame our analysis with Diffusion of Innovation Theory and use a design research methodology that focuses on communication channels, types of knowledge, and stages of the innovation-decision process. Data sources include usage records and survey responses which are analyzed with network diagrams and non-parametric statistics. We find that in comparison to mass media, interpersonal communications tended to result in higher proportions of how-to knowledge and implementation. Three types of opinion leaders were identified through user data and network diagrams. All played critical roles in the tool’s propagation, especially the project collaborators—opinion leaders who actively promoted the CW, in part, because it also propagates their own innovations. Finally, users with self-identified prior principles knowledge showed statistically significantly greater progress in gaining how-to knowledge, but no significant difference in progressing to the implementation stage of the innovation-decision process when compared to users without. 相似文献

This report concerns use of a digital tutor to accelerate veterans’ acquisition of expertise and improve their preparation for the civilian workforce. As background, it briefly discusses the need to improve veterans’ employability, the technology of digital tutoring, its ability to produce advanced levels of technical expertise, and the design, development, and earlier assessment of a specific digital tutor, which motivated use of this tutor to develop veterans’ technical expertise and employability. The report describes the tutor’s use in an experimental program for veterans, an assessment of its success in preparing veterans for employment, and return on investment from its use compared to other investments in education and training. 相似文献

We investigate the evolution of thought using the method of historical reconstruction, the theory of the cultural and historical determinism of psychological development, data on the relationship between morphological studies, modern findings about child development, and the scientific understanding of neural morphogenesis. We argue for classifying protothinking as a separate category to describe a stage when the person thinks objectively without being aware of this process. It is shown that protothinking is a transitional stage between animal thinking and human verbal thinking. We devote particular attention to the process whereby words and verbally expressed thoughts originated. We formulate the conditions that make it possible to trace the process of how speech came into being as sound combinations that are designed to express thought. It is emphasized that individuals are always responsible for discovering words for themselves. We discuss the origins of language, and we note the creative nature of this process. 相似文献

Analysis of academic administrators’ attitudes: annual evaluations and factors that improve teaching
Brian D. Cherry Nathan Grasse Dale Kapla Brad Hamel 《Journal of Higher Education Policy & Management》2017,39(3):296-306
This article examines academic administrators’ attitudes towards the academic evaluation process in the US and those factors that are utilised to improve teaching. We use path regressions to examine satisfaction with evaluation procedures, as well as the direct and indirect effects of these factors on perceptions of whether the evaluation process facilitates quality instruction. With increased pressure for accountability being placed on higher education, it is important to ensure that we are meeting both public and academic expectations. The evaluation process is an important tool to ensure the university’s goals and values are articulated and that academics can be successful in their individual career paths. The problem is most research finds flaws with the current method of evaluation, and academics and academic administrators are sceptical about the process and results. We find there are environmental factors that influence academic administrators’ perceptions of academic evaluations and the ability to improve classroom instruction. 相似文献
