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

Introduction:
Additional nucleotide substitutions in the 3′-untranslated region of prothrombin gene could explain some thrombotic events and also adverse pregnancy outcomes. We describe the first case of a homozygous 20209C>T mutation as the cause of deep vein thrombosis in a Spanish patient.Case and methods:
The 56-year-old male patient with a partial tear of the Achilles tendon developed calf (tibial) deep vein thrombosis after immobilization and was treated with an anticoagulant. To determine if the deep vein thrombosis was of genetic origin, a peripheral blood DNA sample was analysed for the presence of the three most frequent mutations associated with thrombotic events: factor V Leiden (1691G>A), prothrombin (20210G>A) and methylene tetrahydrofolate reductase (677C>T). The presence or absence of the normal allele of prothrombin could not be determined using the PTH-FV-MTHFR StripAssay (Vienna Lab).Results:
Comprehensive analysis showed that the patient had a variant interfering with the polymerase chain reaction product, we sequenced the entire prothrombin gene and found that the patient had a homozygous C>T mutation at position 20209; this interfered with the polymerase chain reaction product, which needs a C at this position to be able to bind to the wild-type probe present in the test strip.Conclusion:
The homozygous 20209C>T mutation and the presence of the mutation 677C>T in heterozygosity explained the patient’s deep vein thrombosis because the combination of mutations would increase the risk of thrombosis. Suitable genetic counselling should be provided to the patient and first-degree relatives as it important to detect prothrombin gene variants that could increase risk for thrombotic events. 相似文献103.
AbstractEnvironmental education (EE) scholars view intergenerational learning as a means to influence adult understandings of and relationships with the environment. Yet EE researchers have studied intergenerational learning in a limited fashion, with no emphasis on its role in higher education. The purpose of this article is to use feminist posthumanist theories to broadly explore intergenerational learning in critical food studies courses taught at the university level. We rely primarily on student coursework and post-course interviews as data sources that convey student perceptions of interactions with their families and the natural world, demonstrating how students develop relational identities shaped by personal experience as well as experiences in the course. To conclude, we discuss both the limitations and implications of this research for the field of EE. 相似文献

The use and development of analogical processes in learning to read in Spanish are presented. In the first experiment, the results show that children of 6 years old show analogical effects in reading pseudowords and that the magnitude of this effect is the same as with 10 years old children. However, it is found that children of 10 years old make many lexicalizations when reading pseudowords (about 50% of the items). In experiment 2 this finding is further analyzed. The results show that 9 years old children make more lexicalizations than adult control subjects do. It is suggested that the development of analogical procedures is a fast process (6 years old children already have done it), but that the precise control of lexical information over perceptual one is a later process. 相似文献

The purpose of the present study is to investigate mathematics anxiety among 220 sixth through eighth grade Turkish students in terms of mathematics achievement levels, perceived enjoyment of the mathematics teaching method, perceived enjoyment of mathematics, and perceived help with mathematics from parents. The Mathematics Anxiety Scale for Primary School Students (Bindak, 2005) was used to assess the levels of mathematics anxiety. A 3 × 2 factorial analysis of variance results showed that there was not a significant interaction effect or main effect of gender; however, there was a significant main effect of grade level. Standard multiple regression analyses show that independent variables accounted for 63% to 70% of variability in the dependent variable. The results also indicate that not only the perceived enjoyment of mathematics, but also the enjoyment of the mathematics teaching method and help with mathematics from parents had a significant effect on mathematics anxiety. 相似文献

Six beginning primary school teachers pioneering the Interactive Teaching approach to science were studied in their first
year of teaching. Interviews with the beginning teachers revcaled that they faced several obstacles to the implementation
of the interactive teaching of science. These included lack of collegial support, lack of feedback on their teaching, difficulty
assessing the learning of their pupils, and the differences between the culture of learning of the alternative science pedagogy
and that of their pupils. By the end of the year, teachers had reconstructed the alternative science pedagogy in ways that
reduced these difficulties. The interviews also provided evidence that ongoing support by teachers and teacher-educators versed
in the alternative pedagogy can make beginning teacher's implementation of the Interactive Teaching of science less difficult.

Education is an indispensable element for the development of society. In Latin America, the point of origin of most of the undocumented immigrants to the United States, equal opportunity in access to education and educational achievement is still pending. The study presented here focuses on the analysis of the expectations of female migrants via Mexico’s northern border, focusing attention on educational attainment as an important aspect of the “American Dream” of the migrant women interviewed and their dependents. 相似文献

This paper reports on findings from a three-year study of project-based learning implemented in the first year of the Industrial Engineering and Management programme, at the University of Minho, Portugal. This particular model was inspired on project-led education (PLE), following Powell and Weenk's [2003. Project-Led Engineering Education. Utrecht: Lemma] work. It aims to analyse students’ perceptions of PLE as a learning device and its implications for faculty and students’ role in teaching and learning. Data collection took place in two phases through individual surveys and focus groups to students. Findings suggest the importance of PLE as a device to enhance meaningful learning and provide evidence from students that it helps to increase their engagement in learning. Implications of PLE for faculty and students role in teaching and learning will be discussed in the paper. 相似文献
