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

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

Previous research has documented a need for the development of a sex education programme in Turkish schools in terms of adolescence readiness and the presence of misconceptions regarding critical aspects of sexual issues. Currently no school‐based sex education is available for Turkish adolescents. This paper presents the development of a contemporary sex education programme for 12‐year‐old to 14‐year‐old adolescents, entitled ‘The Human Development Program for 12–14 Year Old Adolescents’. A five‐step programme development model was used including reviewing internationally recognised sex education programmes for this age group. Sexuality Information and Education Council of United States guidelines were chosen as an educational framework, and Turkish cultural values were integrated into the curriculum. The sex curriculum consists of an eight‐session interactive programme in which parental permission and involvement is required. Five units are presented: human development, relationships, sexual behaviour, sexual health, and society/culture. The programme and a related knowledge assessment tool were reviewed by a group of Turkish professionals and the validity of the educational content was received. The programme was piloted with a group of Turkish adolescents with positive results. Future recommendations include school counsellors implementing this sex educational programme into Turkish schools. 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136.

Against a rapidly changing policy landscape for teacher education, exacerbated by ‘Brexit’ in the UK, findings are presented from an electronic survey of 272 higher-education based teacher educators in England, the Republic of Ireland and Scotland about their experiences of, and priorities for, professional learning. While the data generated were mainly quantitative data, qualitative features were embedded within the survey design. Both types of data have been used to draw out complexities that emerge when exploring a professional group of educators responsible for the preparation of a future generation of teachers. The findings are presented and discussed in relation to the professional demographics of the sample, research expectations placed on them and teacher educators’ priorities for professional learning. Given the unique occupational position of teacher educators, their importance in the quality of teacher education and the lack of formal focus on their professional development, our starting point for teacher educators’ professional development lies in their practice situated and positioned within global, regional, national and local policy contexts. 相似文献

The need for supporting student writing has received much attention in writing research. One specific type of support is feedback—including peer feedback—on the writing process. Despite the wealth of literature on both feedback and academic writing, there is little empirical evidence on what type of feedback best promotes writing in online environments. This article reports on research that tries to determine what type of feedback best improves the quality of collaborative writing and what the effects of feedback are on student learning in an environment based on asynchronous written communication. The results reveal that concerning the type of feedback, epistemic feedback or epistemic and suggestive feedback best improve the quality of collaborative writing performance. The nature of the feedback-giver (whether teacher feedback or teacher and peer) makes a difference to the final text only when the feedback is epistemic, or epistemic and suggestive. 相似文献

Purpose
Preschooler instruction for speech sound awareness typically teaches a progression of speech units from sentences to phonemes, ending at simple first phoneme activities. This study investigates the effects of teaching advanced tasks of phoneme blending and segmenting with and without the larger speech unit of the syllable.Method
Thirty-nine 4-5-year-old typically developing children received twice-weekly small-group instruction in three conditions: two weeks of syllable tasks then four weeks of multiple phoneme tasks (SP), four weeks of multiple phoneme tasks only (MP), or an active control condition of first phoneme instruction (FP).Results
The conditions SP and MP showed large significant gains on blending and segmenting and no significant differences on first phoneme isolating compared to the FP condition. A comparison of SP and MP did not show significant differences on phoneme blending and segmenting, but SP showed significantly more confusion during early sessions of phoneme instruction.Conclusion
This preliminary evidence suggests that preschoolers can improve understanding of phoneme blending and segmenting, without first being taught syllable blending and segmenting, and with no negative effects on first sound awareness. These findings support a more efficient way of teaching preschoolers awareness of the individual sounds of speech. Replication with a larger sample, including children at-risk for literacy difficulties, is recommended before firm conclusions should be drawn. 相似文献140.
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.
