PurposeThe aim of this study was to evaluate the efficacy of a 17-week, 3-component lifestyle intervention for enhancing health behaviors during the coronavirus disease 2019 (COVID-19) pandemic.MethodsA parallel-group (intervention and control) study was conducted amongst 79 airline pilots over a 17-week period during the COVID-19 pandemic. The intervention group (n = 38) received a personalized sleep, dietary, and physical activity (PA) program. The control group (n = 41) received no intervention. Outcome measures for sleep, fruit and vegetable intake, PA, and subjective health were measured though an online survey before and after the 17-week period. The changes in outcome measures were used to determine the efficacy of the intervention.ResultsSignificant main effects for time × group were found for International Physical Activity Questionnaire-walk (p = 0.02) and for all other outcome measures (p < 0.01). The intervention group significantly improved in sleep duration (p < 0.01; d = 1.35), Pittsburgh Sleep Quality Index score (p < 0.01; d = 1.14), moderate-to-vigorous PA (p < 0.01; d = 1.44), fruit and vegetable intake (p < 0.01; d = 2.09), Short Form 12v2 physical score (p < 0.01; d = 1.52), and Short Form 12v2 mental score (p < 0.01; d = 2.09). The control group showed significant negative change for sleep duration, Pittsburgh Sleep Quality Index score, and Short Form 12v2 mental score (p < 0.01).ConclusionResults provide preliminary evidence that a 3-component healthy sleep, eating, and PA intervention elicit improvements in health behaviors and perceived subjective health in pilots and may improve quality of life during an unprecedented global pandemic.  相似文献

College-level biology courses contain many complex processes that are often taught and learned as detailed narratives. These processes can be better understood by perceiving them as dynamic systems that are governed by common fundamental principles. Conservation of matter is such a principle, and thus tracing matter is an essential step in learning to reason about biological processes. We present here multiple-choice questions that measure students' ability and inclination to trace matter through photosynthesis and cellular respiration. Data associated with each question come from students in a large undergraduate biology course that was undergoing a shift in instructional strategy toward making fundamental principles (such as tracing matter) a central theme. We also present findings from interviews with students in the course. Our data indicate that 1) many students are not using tracing matter as a tool to reason about biological processes, 2) students have particular difficulties tracing matter between systems and have a persistent tendency to interconvert matter and energy, and 3) instructional changes seem to be effective in promoting application of the tracing matter principle. Using these items as diagnostic tools allows instructors to be proactive in addressing students' misconceptions and ineffective reasoning.  相似文献

In this paper, we identify beliefs about teaching and patterns of instruction valued and emphasized by science, technology, engineering, and mathematics faculty in higher education in the USA. Drawing on the notion that effective teaching is student-centered rather than teacher-centered and must include a balance of knowledge-, learner-, community-, and assessment-centered learning environments; we use qualitative interview data to explore how faculty's reported beliefs about teaching are associated with their consideration of these four types of environments. Findings indicated that although a range of beliefs about teaching emerged, most were firmly located in knowledge-centered learning environments, with little or no focus on the remaining three learning environments. Furthermore, even patterns of instruction that were heavily student-centered were situated within a knowledge-centered learning framework. We argue that for student-centered instruction to be truly successful, faculty must consider all four learning environments in crafting and facilitating the classroom environment.  相似文献

¿Matemáticas para todos o matemáticas de élite? ¿Lenguaje matemático o matemática aplicada? En la base de las últimas reformas educativas de todo el mundo no dejan de estar presentes dilemas, reales unas veces, ficticios otras, que tienen mucho que ver con los supuestos políticos—ideológicos—que sustenten los diseñadores de esa reforma respecto al papel de la educación y a los que no se sustrae la enseñanza de las matemáticas…  相似文献

As new technologies promise to be an enduring feature of the landscape of teachers’ work, we consider how teachers implicitly bring stories forward into their classroom explorations with new media as a part of their ‘informal learning’. By ‘stories’ is meant specific classroom texts as well as preferred teacher practices with those texts. The article represents a reflection on the methodological role that ‘elicitation’ can play in drawing out teacher thinking during a time of professional change, thinking that would otherwise likely remain embedded, particularly when teachers’ attention is focused forward on innovation in practice. The methodological use of ‘elicitation’ emerged in the first year of an ongoing teacher action research study, in which seven teachers have been involved in a professional development initiative that actively engages teachers in examining changing literacy formations, beginning with the teachers’ own literacy formations. The methodological practice of elicitation borrows from phenomenology, ethnomethodology, narrative research, reader response theories, curriculum theory and psychoanalysis, and emerged as a way to acknowledge the life histories that teachers were bringing to their professional development with new media. We suggest that elicitation can potentially draw out deep and sustaining sources of a teacher’s commitment, as well as resistance, to change. It can help disclose the tensions between commitment and resistance that even teachers who voluntarily undertake to incorporate new technologies into their practice may experience. Within a teacher action research framework, elicitation can also serve to remind teachers (and others) of the value of what they know and are learning, thus contributing to teachers developing a ‘scholarship of practice’ in response to any actual or perceived ‘intensification’ of their work.  相似文献

This study is an examination of the state of the liberal arts curriculum in community colleges in three geographic regions of the United States. From a constructivist paradigm and using globalization theory as a theoretical framework, this multiple case study examined faculty work life and administrative processes related to curriculum change in merged community and technical colleges. Through an examination of research on globalization, mergers, and trends in the general education and liberal arts curriculum, a gap in the literature emerged in the studies of community college curriculums after merger. This study considers whether the focus on workforce development and decrease in the transfer mission has diminished the liberal arts courses in the college curriculum. Research on liberal arts courses identified them as courses that emphasize higher order thinking and the development of intellectual skills needed to engage in a democratic society. If students are not exposed to these skills, it may have a detrimental effect on a democratic society. Study findings suggested that the English and communication curriculums are narrowing and the mission is more toward workforce skill preparation. Also, the changing demographics of today[#x02019]s community college students, as well as the ongoing budget constraints, create challenges and frustrations for faculty members.  相似文献
