We present an innovative course-based undergraduate research experience curriculum focused on the characterization of single point mutations in p53, a tumor suppressor gene that is mutated in more than 50% of human cancers. This course is required of all introductory biology students, so all biology majors engage in a research project as part of their training. Using a set of open-ended written prompts, we found that the course shifts student conceptions of what it means to think like a scientist from novice to more expert-like. Students at the end of the course identified experimental repetition, data analysis, and collaboration as important elements of thinking like a scientist. Course exams revealed that students showed gains in their ability to analyze and interpret data. These data indicate that this course-embedded research experience has a positive impact on the development of students’ conceptions and practice of scientific thinking. 相似文献

Biomechanics helps us understand the association between technique changes and performance improvement during learning. The aim of this research was to investigate joint kinetic characteristics of technique during learning of the longswing on the high bar. Twelve male, novice participants took part in the learning study. During swing attempts in 8 weekly testing sessions, kinematic data were collected. Inverse dynamics analysis was performed from known zero forces at the toes to quantify joint moments and power at the hips and shoulders. Key biomechanical constraints that limited performance outcome were identified based on changes in joint kinetics during learning. These constraints were the ability to perform a large shoulder power and to overcome passive kinetics acting during the downswing. Constraints to action at the level of joint kinetics differentially challenge learners and therefore could underpin more individual, specific learning interventions. Functional phases, defined by maximum hyperextension to flexion of the hips and maximum flexion to extension of the shoulders, did not describe the key joint kinetics of the hip and shoulder for novices. The functional phases may serve however to identify novices that were unable to overcome the passive kinetic constraint. 相似文献

Background: High-intensity training has been associated with atrial remodelling and arrhythmias in men. Our purpose was to analyse atrial performance in female endurance athletes, compared to male athletes and controls. Methods: This was a cross-sectional study. We included four groups: female athletes, females controls, male athletes and male controls. Left (LA) and right atrial (RA) volumes and function were assessed using 2D and speckle-tracking echocardiography to determine peak atrial strain-rate at atrial (SRa) and ventricular contraction (SRs), as surrogates of atrial contractile and reservoir function, respectively. ANOVA and Bonferroni’s statistical tests were used to compare variables among groups. Results: We included 82 subjects, 39 women (19 endurance athletes, 20 controls) and 43 men (22 endurance athletes, 21 controls). Mean age was similar between groups (36.6?±?5.6 years). Athletes had larger bi-atrial volumes, compared to controls (women, LA 27.1 vs. 15.8?ml/m2, p?<?0.001; RA 22.31 vs. 14.2?ml/m2, p?=?0.009; men, LA: 25.0 vs. 18.5?ml/m2, p?=?0.003; RA 30.8 vs. 21.9?ml/m2, p?<?0.001) and lower strain-rate (women, LASRa ?1.60 vs. ?2.18?s?1, p?<?0.001; RASRa ?1.89 vs. ?2.38?s?1, p?=?0.009; men, LASRa ?1.21 vs. ?1.44?s?1, p?=?1; RASRa ?1.44 vs. ?1.60?s?1, p?=?1). However, RA indexed size was lower and bi-atrial deformation greater in female athletes, compared to male athletes. Conclusions: The atria of both male and female athletes shows specific remodelling, compared to sedentary subjects, with larger size and less deformation at rest, particularly for the RA. Despite a similar extent of remodelling, the pattern in women had greater bi-atrial myocardial deformation and smaller RA size. 相似文献

This paper explores discursive ways Chinese American older adults with type 2 diabetes mellitus (T2DM) take ownership of their health management. Fifteen patient stakeholders with T2DM took part in four focus group interviews. We used qualitiative discourse analysis to examine how participants used the phrase, “We (Tong) Chinese,” and variants, to index models of Chinese-living-in-the-U.S. personhoods, to incorporate “Chinese” and “western” ways of doing health management, to be Chinese American, and to interact with medical practitioners. We show how terms like “Tong” distinguish transnational boundaries and position participants in claiming “Chinese-in-America-ness” in relevant ways. Findings have implications for healthcare providers, health education, and intercultural communication. 相似文献

Growing pressures for more effective education programs at community hospitals demand better and more responsive hospital library resources and services. It is suggested that, with a modest amount of additional training and support, a community hospital librarian can play a key role in (1) improving the effectiveness of the hospital's library services and resources, (2) assisting hospital educators with the task of developing, implementing, and evaluating education programs, and (3) facilitating coordination of health information resources and services with all aspects of hospital education programs. An expanded, more active role, that of the Health Information Specialist, is suggested for hospital librarians. A one-week training program for librarians and special orientation for hospital educators and administrators plus followup field consultation for all three is described and proposed as an implementation strategy to provide the background and impetus needed to help hospital librarians evolve and expand their functional role into that of a Health Information Specialist. 相似文献

History courses at The University of Auckland are typically assessed at two or three moments during a semester. The methods used normally employ two essays and a written examination answering questions set by the lecturer. This study describes an assessment innovation in 2008 that expanded both the frequency and variety of activities completed by 182 undergraduates taking a course on the history of African‐American freedom struggles. All week‐by‐week tutorial assignments were collected for textual analysis to see if students were moving beyond the recollection and regurgitation of facts (surface learning) and instead were dealing with the deeper historical issues. The quality of student work coupled with our own classroom observations indicate that innovative assessment methods at regular moments during the semester made a positive difference to the student learning experience. 相似文献

ABSTRACTThis article is an exploration in the mode of thinking of refugee youth on the relations of ‘democracy’ and ‘dictatorship.’ Tracing the geopolitical relations of authoritarian and democratic forms of governing we demonstrate the manner in which these political forms are socio-historically interdependent yet appear as politically distinct, which we understand as an ideological form of consciousness. Expanding out from interviews and focus groups conducted with refugee youth from the Middle East and North Africa who arrived in Canada to resettle, our analysis attempts to go deeper than that simply creating space for the voices of refugee youth. Instead, we want to theorise from the data to reconceptualise the social and economic projects that have been named as democratisation or youth at-risk. The conscious reproduction of democracy and dictatorship as distinct political forms requires that refugee youth learn to live in and act upon their world through an ideological mode of consciousness that furthers the relations of global capitalism and encourages young people to align their aspirations with neoliberalism. We, therefore, aim to reorient theorisations of democracy and dictatorship, and in doing so, challenge the forms of consciousness and praxis that arise from the bourgeois regime of political rights. 相似文献
