Matters of data privacy related to social media are increasingly relevant for educators as happenings such as the 2018 Cambridge Analytica scandal have attracted public attention. Many educators use social media for professional purposes, including with their students and should, therefore, be knowledgeable regarding data privacy issues that impact education. This research explores this issue from an interpretive paradigm based on a mixed-methods approach derived from survey data from an international sample of 148 pre-service teachers who were studying education courses at three universities. Data suggest that pre-service teachers see both educational and distracting potential in social media, but lack knowledge regarding relevant policies and regulations, which reflects trends in the broader population. Attitudes toward educational social media use were not correlated with awareness of data privacy policies. However, comfort with companies’ use of personal and student data and faith in governments’ capacity to regulate social media companies were correlated. We discuss our findings in relation to the use of social media and related data privacy considerations and the need for data literacy training in teacher education programs. We include recommendations in light of the findings. 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57.

ABSTRACTReform initiatives around the world are reconceptualising science education by stressing student engagement in science practices. Yet, science practices are language-intensive, requiring students to have strong receptive and productive language proficiencies. It is critical to address these rigorous language demands to ensure equitable learning opportunities for all students, including English language learners (ELLs). Little research has examined how to specifically support ELL students’ engagement in science practices, such as argumentation. Using case-study methodology, we examined one middle school science teacher's instructional strategies as she taught an argumentation-focused curriculum in a self-contained ELL classroom. Findings revealed that three trends characterized the teacher’s language supports for the structural and dialogic components of argumentation: (1) more language supports focused on argument structure, (2) dialogic interactions were most often facilitated by productive language supports, and (3) some language supports offered a rationale for argumentation. Findings suggest a need to identify and develop supports for the dialogic aspects of argumentation. Furthermore, engaging students in argumentation through productive language functions could be leveraged to support dialogic interactions. Lastly, our work points to the need for language supports that make the rationale for argumentation explicit since such transparency could further increase access for all students. 相似文献

The study explores the consequences, for participating schools, of the implementation of a system for the identification and selection of academically talented students, in the context of an extracurricular enrichment program operating at Pontificia Universidad Católica de Chile. The participants were 73 students, 50 teachers, and seven members of the school administration, in seven schools. Data were collected through interviews and focus groups. The results indicated that the identification and selection processes have mostly positive effects on teachers and students. Some potentially negative effects were also detected for the classmates of the talented students, which relate mainly to the manner in which information was handled. Possible implications of these findings for this program for talented children and other similar programs are discussed. 相似文献

The pedagogical integration of computing is interesting in educational contexts based on the contributions of Seymour Papert and Wing’s concept of computational thinking. Integrating arts in education can lead to the design of activities using Scratch combined with devices. The main goal is to evaluate the integration of computational thinking in art education making use of technological resources, sensor cards and minicomputers, with a student-centred pedagogical approach. This research assesses the results of a control group of 35 students and an experimental group of 109 students in four different schools, using Mann-Whitney’s U-test for independent samples assessing ‘Active Learning’, ‘computational concepts’ and ‘fun’ scales. Applying data triangulation, and consistent with design-based research, the results of interviews and focus groups reinforced the results obtained in the aforementioned test, providing validity to the study. There are advantages regarding student interest, motivation and commitment related to programming technologies in art and education, particularly pedagogical sessions with music. Handling devices, sensors and Raspberry Pi provides participating students with a factor of commitment and enthusiasm, with significant improvements. Working with coding and devices brings an additional advantage in the development of computational thinking and digital competence. The results show an increase in creativity and artistic competence related to the ability to create music from the activities and technological resources described in the technological intervention. 相似文献

We analyse the internationalisation process in business schools as a response to the globalisation phenomena and argue that environmental pressures, isomorphic forces, the pool of internal resources and the alignment of the process with the institution’s general strategic plan are the main determinants of a successful internationalisation process. These determinants, two external and two internal, find support in different theoretical frameworks such as contingency, isomorphism, resource-based view and strategic management theories. We use these theoretical approaches to discuss four propositions that explain the implementation of an appropriate internationalisation process for a business school. This paper contributes to the literature concerned with the internationalisation processes in higher education institutions highlighting the main factors that should be taken into account by school deans, university provosts, university boards and educational policymakers in guiding internationalisation process at institutional and national/sector levels. 相似文献
