The goal of our research was to study different forms of organization of pretend play on children's cognitive performance in a mixed-age environment. We studied two forms of management of the playing process: (a) teacher-directed play with simultaneous involvement of all children in the classroom, where the teacher plays the dominant role in the education process directing children's activity, and (b) child-directed play in various small groups. Twenty-six observations were performed on 51 children in two mixed-age classrooms. The mean age of the children was 4.6 years, with age span from 3 to 6 years. Data were collected regarding children's affective and cognitive behavior according to generally accepted taxonomies: Bloom for the cognitive domain, and Krathwohl for affective domain. We found a significant increase in cognitive manifestations during direction of the playing process in groups compared with frontal management of the lesson (113.1 ± 12.1 vs. 45.7 ± 10.3, mean ± SEM, p < 0.0001), which is related with better employment of the powerful education engine of the free-play children.  相似文献

The discussions held in specifying an automaticvehicle as a project in a distance work-relatedcourse are in focus for an analysis of learningin networked discussions. Learning ischaracterised as coming to experience things indistinctly new ways, in keeping with theunderlying phenomenographic research approachfor the study. Group discussions are seen asone feature in the experience of, and theformation of, the context for learning, in anexperiential interpretation of activitysystems. The analysis has led to theidentification of pivotal contributions todiscussions that can be said to afford learningwithin the group, in the sense of openingdimensions of variation around criticalfeatures of the task. This is developed toproduce a taxonomy of contributions, withparticipatory, factual, reflective and learningcontributions, suggested to be necessary,though not sufficient, conditions for learning.The taxonomy is illustrated and discussed, asare its implications for tutoring in networkedcourses of this type.  相似文献

Chile’s higher education system stands out as being one of the most privatized and open to the market in the world. Recently, the Chilean Congress passed Law # 20.027 of 2005, which provides the legal framework for the creation of a student loan system guaranteed both by the State and by higher education institutions (HEIs), financed by the private capital market through the securitization of the loans. The system operated for the first time in 2006, where approximately 21,000 students were able to access financing of their higher education for the remainder of their careers. It is expected that as the system matures, more and better information will be available, which will benefit the students and the HEIs; and it is highly likely that the current number of financed students could grow significantly in the next few years. The purpose of this article is to describe the outstanding characteristics of this system, explain its conceptual basis and analyze the public policy choices available in its design.

Flow is a state of total absorption and concentration in an activity that is desirable for students, as it enhances the learning experience. Due to the importance of flow for learning, this research investigates the influence of three flow preconditions—namely balance of skill and challenge, feedback and goal clarity—on students' flow, operationalized as heightened concentration, sense of control and autotelic experience, while using clickers—a type of polling device. The study also explores the impact of concentration, sense of control and autotelic experience on students' perceived learning and satisfaction. Based on a survey of 204 undergraduate students who use clickers in the classroom, the findings show that balance of skill and challenge has a positive influence on students' concentration, sense of control and autotelic experience. Both feedback provided by clickers and goal clarity have a positive influence on concentration and sense of control, but do not influence the autotelic experience. Findings also corroborate the positive impact of concentration and sense of control experienced by students on perceived learning. Finally, autotelic experience predicts both perceived learning and satisfaction.  相似文献

The stressors associated with poverty increase the risks for externalizing psychopathology; however, specific patterns of neurobiology and higher self-regulation may buffer against these effects. This study leveraged a randomized control trial, aimed at increasing self-regulation at ~11 years of age. As adults, these same individuals completed functional MRI scanning (Mage = 24.88 years; intervention n = 44; control n = 49). Functional connectivity between the hippocampus and ventromedial prefrontal cortex was examined in relation to the intervention, gains in self-regulation, and present-day externalizing symptoms. Increased connectivity between these brain areas was noted in the intervention group compared to controls. Furthermore, individual gains in self-regulation, instilled by the intervention, statistically explained this brain difference. These results begin to connect neurobiological and psychosocial markers of risk and resiliency.  相似文献

The paper argues that what is left behind in the current era of accountability is the educational content. The authors present shedding the content as the great challenge of teaching and learning in today’s schools. They turn to the tradition of Bildung and outline the theoretical background for the content-focused approach to (research on) teaching and learning. Their approach is based on analyses of authentic (real-life) teaching and learning situations. The paper highlights how didactic case studies can be used to generalize the findings across individual cases. Within the multiple case studies, 44 didactic case studies were reanalysed to identify didactic formalisms, i.e. problems in the semantic and logical structure of educational content, which corrupt the quality of instruction. Two specific types of didactic formalism are described in detail; stolen cognition and concealed cognition. Stolen cognition prevents cognitive activation of students when the teacher over-reduces the space allowed for the students’ cognitive work with the content, concealed cognition are instances of purposeless cognitive activation of students due to their being disconnected from the content.  相似文献

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country.  相似文献

The use of formative and shared or co-assessment has been shown to improve the motivation, involvement and learning of university students. The aim of this study is to analyse the effect that implementing these processes has on university students’ perception of their acquisition of transversal competences. The participants in the study were 1021 students from five Spanish universities taking degree courses in primary education or physical education and sport science. They all experienced formative and shared or co-assessment throughout a complete academic year of their courses. For the data collection, a Self-Perception Scale of Transversal Competences was created, which had adequate values of reliability and validity. Using a transversal design (inter-subjects), inferential statistical analysis was undertaken of the differences in means between the perception of a range of transversal competences before and after the course. The results show significant perceived improvements at the end of the course for most of the competences analysed, which indicates, among other thing, the value and importance of this type of assessment for the educational process.  相似文献
