Scientific competencies, as defined in the German competency framework, describe the ability to think independently and act scientifically which is a central component of medical education. This report describes integration of scientific competencies into anatomical teaching. Based on findings seen in two consecutive years of dissection courses, students worked on either a case report (n = 70) or an original research study (n = 6) in the format of a scientific poster while learning to use primary literature. Posters were evaluated by juror teams using standardized evaluation criteria. Student perception of the project was assessed by quantitative and qualitative data obtained from the faculty's course evaluation and an online-survey. Overall, students worked collaboratively and invested extra-time (median 3.0 hours) in poster creation. Primary literature was integrated in 90.8% of the posters. Overall poster quality was satisfactory (46.3 ± 8.5 [mean ± standard deviation] out of 72 points), but several insufficiencies were identified. Students integrated information gained from the donor's death certificate, post-mortem full-body computed tomography (CT) scan (22.4%), and histopathological workup (31.6%) in their case reports. Students responded positively about learning new scientific skills (median 4.0 on a six-point Likert scale), but free-text answers revealed that some students experienced the project as an extra burden in a demanding gross anatomy course. In summary, it was feasible to introduce students to scientific skills during the dissection course and to increase interest in science in approximately a third of the survey respondents. Further adjustments to ensure the posters' scientific quality might be necessary for the future. 相似文献
Marie Ståhl and Anita Hussénius have defined what discourses dominate national tests in chemistry for Grade 9 in Sweden by using feminist, critical didactic perspectives. This response seeks to expand the results in Ståhl and Hussénius’s article Chemistry inside an epistemological community box!—Discursive exclusions and inclusions in the Swedish national tests in chemistry, by using different facets of gender awareness. The first facet—Gender awareness in relations to the test designers’ own conceptions—highlighted how the gender order where women are subordinated men becomes visible in the national tests as a consequence of the test designers internalized conceptions. The second facet—Gender awareness in relation to chemistry—discussed the hierarchy between discourses within chemistry. The third facet—Gender awareness in relation to students—problematized chemistry in relation to the students’ identity formation. In summary, I suggest that the different discourses can open up new ways to interpret chemistry and perhaps dismantle the hegemonic chemistry discourse. 相似文献
A highly skilled maintainer is the most important organisational asset pivotal for achieving quality software, strategic for improving maintenance and development processes, essential for remaining competitive and critical for business survival. This requires that universities properly prepare students to enter the maintenance workforce and that maintenance organisations actively build and maintain their human knowledge and skill base. In this paper, we present Corrective Maintenance Maturity Model (CM 3): Maintainers' Education and Training – a maturity model for educating and training maintenance engineers within corrective maintenance. This model is presently being developed at ABB by the Software Maintenance Laboratory (SML). Our goal is to provide guidance to ABB and industrial organisations worldwide in the process of building or improving their most important asset – people. Each process element presented in this paper is matched against its corresponding process element at ABB. Hence, this paper may also be regarded as a report on the state of the current practice of educating and training maintainers at ABB. 相似文献
The present study reports an empirical investigation into concept formation of young children. Based on interviews conducted before and after participating in a playfully enacted chemistry lesson at a culture center, it is analyzed how 6-year-old children conceptualize water, molecule, and chemistry. Theoretically, the study is informed by Vygotsky’s cultural-historical perspective on concept formation. The empirical data consist of pre- and post-interviews with children and documentation of their participation in the intermediate activity. This documentation is used in the post-interviews as a mutual ground for talking with the children about what they remember and how they understand the activity they participated in and what the activity intended to illustrate. The results are presented in terms of three inductively generated categories: ‘everyday’, ‘experientially-based’, and ‘generalized experiences’ concepts, respectively. The implications of these findings for early childhood chemistry (science) education are discussed.
Background:In a sprint cross-country(XC)ski competition,the difference in recovery times separating the first and the second semi-final(SF)heats from the final(F)may affect performance.The aim of the current study was to compare the effects of longer vs.shorter recovery periods prescribed between the 3 knock-out races of a simulated sprint XC ski competition involving a prologue(P),quarter-final(QF),SF,and F.Methods:Eleven well-trained XC ski athletes completed 2 simulated sprint XC ski competitions on a treadmill involving 4×883-m roller-ski bouts at a 4°incline using the gear 3 ski-skating sub-technique.The first 3 bouts were completed at a fixed speed(PFIX,QFFIX,and SFFIX)corresponding to~96%of each individual’s previously determined maximal effort.The final bout was performed as a self-paced sprint time trial(FSTT).Test conditions differed by the time durations prescribed between the QFFIX,SFFIX,and FSTT,which simulated real-world XC ski competition conditions using maximum(MAX-REC)or minimum(MIN-REC)recovery periods.Results:The FSTT was completed 5.4±5.5 s faster(p=0.009)during MAX-REC(179.2±18.1 s)compared to MIN-REC(184.6±20.0 s),and this was linked to a significantly higher power output(p=0.010)and total metabolic rate(p=0.009).The pre FSTT blood lactate(BLa)concentration was significantly lower during MAX-REC compared to MIN-REC(2.5±0.8 mmol/L vs.3.6±1.6 mmol/L,respectively;p=0.027),and the pre-to-post FSTT increase in BLa was greater(8.8±2.1 mmol/L vs.7.1±2.3 mmol/L,respectively;p=0.024).No other differences for MAX-REC vs.MIN-REC reached significance(p>0.05).Conclusion:Performance in a group of well-trained XC skiers is negatively affected when recovery times between sprint heats are minimized which,in competition conditions,would occur when selecting the last QF heat.This result is combined with a higher pre-race BLa concentration and a reduced rise in BLa concentration under shorter recovery conditions.These findings may help inform decision making when XC skiers are faced with selecting a QF heat within a sprint competition. 相似文献
This study explores seven Swedish top-level women’s soccer players’ career development experiences. Data were produced through semi-structured interviews and a biographical mapping grid. The theoretical framework of ‘careership’ was employed to understand the data. The results showed homogenous career paths. Moreover, the data show that the players decided at a young age to pursue a career in soccer; experienced the transition from junior to senior level soccer as difficult because of a lack of physical preparedness; soccer over school commitments. We recommend that soccer stakeholders (e.g. federations, clubs, coaches) give the transition from junior to senior level soccer special attention to prevent intense demands that may cause dropout. We further propose that if athletes should give sport and education equal priority, the Swedish dual career concept of high school education and sport needs further reflection and adjustment. 相似文献
The aim of the present study was to examine the movement patterns, ball skills, and the impressions of Swedish elite football players during competitive games on artificial turf and natural grass. Time - motion analyses (36 observations) and technical analyses (16 team observations) were performed and 72 male and 21 female players completed a questionnaire. No differences were observed between artificial turf and natural grass in terms of total distance covered (mean 10.19 km, s = 0.19 vs. 10.33 km, s = 0.23), high-intensity running (1.86 km, s = 0.10 vs. 1.87 km, s = 0.14), number of sprints (21, s = 1 vs. 22, s = 2), standing tackles (10, s = 1 vs. 11, s = 1) or headers per game (8, s = 1 vs. 8, s = 1), whereas there were fewer sliding tackles (P < 0.05) on artificial turf than natural grass (2.1, s = 0.5 vs. 4.3, s = 0.6). There were more short passes (218, s = 14 vs. 167, s = 12) and midfield-to-midfield passes (148, s = 11 vs. 107, s = 8) (both P < 0.05) on artificial turf than natural grass. On a scale of 0-10, where 0 = "better than", 5 = "equal to", and 10 = "worse than", the male players reported a negative overall impression (8.3, s = 0.2), poorer ball control (7.3, s = 0.3), and greater physical effort (7.2, s = 0.2) on artificial turf than natural grass. In conclusion, the running activities and technical standard were similar during games on artificial turf and natural grass. However, fewer sliding tackles and more short passes were performed during games on artificial turf. The observed change in playing style could partly explain the male players' negative impression of artificial turf. 相似文献
In this article, we investigate ‘no touch policies’ as a practical teacher concern that includes the body as a location, a source and a means in educational activity. We argue that to understand issues regarding physical touch within school practice we must conceive it as deeply associated with specific teaching techniques. Thus, the didactical challenge is not found in argumentations about the pro and cons of physical touch, but through analysis of how teachers handle student interaction and teaching intentions.
We consider teaching as a caring profession. Caring, as a practical teacher concern, requires wisdom regarding the right time to use bodily touch and to refrain from such use. This wisdom involves the ability to discern people’s needs, desires, interests and purposes in particular situations and act appropriately. From a body pedagogical perspective we approach intergenerational touch not only as a discursive and power-related question but as an essential tension in the intersection of the; ambiguity attendant to any intentional act such as teaching, the conflict between the ethics of care and the ethics of justice, and finally, the paradox of caring.
We draw on interviews with PE-teachers in Swedish primary, secondary and upper-secondary schools and analyses of a collection of techniques of bodily touch that are established and practiced with specific pedagogical purposes. The results shows PE teacher’s competence in handling different functions of intergenerational touch in relation to three different techniques of bodily touch; (1) Security touch, which is characterized by intentions to handle the fragile; (2) Denoting touch, which is characterized by intentions to handle learning content and (3) Relational touch, which is characterized by caring intentions. Each of these is of importance for the teachers in carrying out their call to teach and each of these relies on professional assessments whether or not it meets its intended purpose. 相似文献
The present study contributes to a growing line of research exploring the role of post sex communication in building and sustaining romantic relationships. More specifically, this study explores the use of relational maintenance strategies during the post sex time interval (PSTI). One-hundred and fifty-two individuals completed surveys after sexual activity and indicated the relational maintenance strategies they enacted during the PSTI. Results revealed that individuals enact the strategies of positivity and assurances to the greatest degree during the PSTI. Furthermore, extending the post sex disclosures model, results revealed that orgasm predicted differences in the use of assurances during the PSTI and that the strategy of assurances mediated the association between orgasm and several relationship outcomes (i.e., liking, commitment, control mutuality, and satisfaction). These findings suggest that individuals may use the PSTI as a time to reinforce their commitments to their partners, and that such behavior is associated with characteristics of the sexual episode and relationship outcomes. The implications of these findings for research on relational maintenance and post sex behavior are discussed. 相似文献
