Biomechanics education is a vital component of kinesiology, sports medicine, and physical education, as well as for many biomedical engineering and bioengineering undergraduate programmes. Little research exists regarding effective teaching strategies for biomechanics. However, prior work suggests that student learning in undergraduate physics courses has been aided by using the Just-in-Time Teaching (JiTT). As physics understanding plays a role in biomechanics understanding, the purpose of study was to evaluate the use of a JiTT framework in an undergraduate biomechanics course. This two-year action-based research study evaluated three JiTT frameworks: (1) no JiTT; (2) mathematics-based JiTT; and (3) concept-based JiTT. A pre- and post-course assessment of student learning used the biomechanics concept inventory and a biomechanics concept map. A general linear model assessed differences between the course assessments by JiTT framework in order to evaluate learning and teaching effectiveness. The results indicated significantly higher learning gains and better conceptual understanding in a concept-based JiTT course, relative to a mathematics-based JiTT or no JiTT course structure. These results suggest that a course structure involving concept-based questions using a JiTT strategy may be an effective method for engaging undergraduate students and promoting learning in biomechanics courses. 相似文献

Definitional issues in emotion regulation research 总被引:1,自引:0,他引:1
Operational definitions of emotion regulation are frequently unclear, as are links between emotion regulation measures and underlying theoretical constructs. This is of concern because measurement decisions can have both intentional and unintentional implications for underlying conceptualizations of emotion regulation. This report examines the implications of some such decisions, including (a) focusing on types versus total amount of emotion regulation, (b) determining distinctiveness of measures of emotion versus emotion regulation strategies, (c) deciding whether and how to examine temporal sequencing of strategy use and emotion, d) using discrete versus global emotion measures, and (e) determining when emotion is being regulated. Finally, the need for better conceptualizations and empirical assessments of adaptive (vs. maladaptive) emotion regulation is discussed. 相似文献

Unlike a jigsaw puzzle where a piece must fit in only one way to complete a picture, the seven pieces of a geometric tangram
can be arranged in many different ways to make figures of birds, animals, people, and objects. This article presents a Tangram
Teaching Guide to provide a five-step developmental sequence for teaching tangramming to young children. Teaching resources
are included, and a checklist provides a summary outline of the teaching sequence. Tangram experiences help children develop
positive attitudes toward geometry, further their shape identification and classification skills, and foster and understanding
of basic geometric concepts and relationships. 相似文献

Purpose: The purpose of this study was to examine differences in heart rate recovery (HRRec) and oxygen consumption recovery (VO2 recovery) between young healthy-weight children and children with obesity following a maximal volitional graded exercise test (GXTmax). Method: Twenty healthy-weight children and 13 children with obesity completed body composition testing and performed a GXTmax. Immediately after the GXTmax, HRRec and VO2 recovery were measured each minute for 5 consecutive minutes. Results: There were no statistically significant group differences in HRRec for the 5 min following maximal exercise, Wilks’s Lambda = .885, F(4, 28) = 0.911, p = .471, between the healthy-weight children and children with obesity despite statistically significant differences in body fat percentage (BF%; healthy-weight children, 18.5 ± 6.1%; children with obesity, 41.1 ± 6.9%, p < .001) and aerobic capacity relative to body mass (VO2 peak; healthy-weight children, 46.8 ± 8.2 mL/kg/min; children with obesity, 31.9 ± 4.7 mL/kg/min, p < .001). There were statistically significant differences in VO2 recovery for the 5 min following exercise, Wilks’s Lambda = .676, F(4, 26) = 3.117, p = .032. There were no statistically significant correlations between HRRec and body mass index (BMI), BF%, VO2peak, or physical activity. Conclusions: In a healthy pediatric population, obesity alone does not seem to significantly impact HRRec, and because HRRec was not related to obesity status, BMI, or BF%, it should not be used as the sole indicator of aerobic capacity or health status in children. Using more than one recovery variable (i.e., HRRec and VO2 recovery) may provide greater insight into cardiorespiratory fitness in this population. 相似文献

Clinical experience demonstrates that many chronically ill children have an unstable course of illness ending in tertiary care, not because of extraordinary disease, but because they come from dysfunctional and neglectful households. Families frequently cannot or will not adapt to the demands of their chronically ill child. This study substantiates the extent to which neglect and family dysfunction have contributed to the need for hospitalization of asthmatic children at National Jewish. Neglect accelerates the cycle of morbidity and stress associated with illness. Using a measure of global functioning, we demonstrate a psychologic morbidity associated with medical neglect. We discuss children at imminent risk in their home environment and the process of seeking alternative placements. We acknowledge gaps in delivery of health care to this difficult, treatment-resistant population and encourage development of day treatment and home outreach programs. 相似文献
