Scientific knowledge, including the critical evaluation and comprehension of empirical articles, is a key skill valued by most undergraduate institutions for students within the sciences. Students often find it difficult to not only summarize empirical journal articles, but moreover to successfully grasp the quality and rigor of investigation behind the source. In this paper, we use instructional scaffolds (reading worksheets, RWs, with tutorials) to aid students in being able to comprehend, and ultimately transfer, the skills necessary in critically evaluating primary sources of research. We assess students’ learning of these skills on a multiple-choice assessment of Journal Article Comprehension (JAC). Students in experimental classes, who received instructional scaffolds, improved on the JAC post-test compared with students in control classes. This result shows that students are acquiring fundamental research skills such as understanding the components of research articles. We also showed that improvement on the JAC post-test for the experimental class extended to a written summary test. This result suggests that students in the experimental group are developing discipline-specific science process skills that allow them to apply JAC skills to a near-transfer task of writing a summary.  相似文献

The complexity of the material being taught in clinical neuroscience within the medical school curriculum requires creative pedagogies to teach medical students effectively. Many clinical teaching strategies have been developed and are well described to address these challenges. However, only a few have been evaluated to determine their impact on the performance of students studying clinical neuroscience. Interactive, 2‐hour, self‐directed small‐group interactive clinical case‐based learning sessions were conducted weekly for 4 weeks to integrate concepts learned in the corresponding didactic lectures. Students in the small groups analyzed cases of patients suffering from neurological disease that were based on eight learning objectives that allowed them to evaluate neuroanatomical data and clinical findings before presenting their case analysis to the larger group. Students’ performances on the formative quizzes and summative tests were compared to those of first‐year medical students in the previous year for whom the self‐directed, small‐group interactive clinical sessions were not available. There was a significant improvement in the summative performance of first‐year medical students with self‐directed clinical case learning in the second year (Y2) of teaching clinical neuroscience (P < 0.05) when compared with first‐year students in the first year (Y1) for whom the self‐directed learning approach was not available. Student performance in the formative assessments between Y1 and Y2 was not significantly different (P = 0.803). A target of ≥70% student scoring above 80% in the final summative examination was met. The current study revealed evidence for the impact and educational outcomes of a self‐directed, clinical teaching strategy in a clinical neuroscience curriculum for first‐year medical students.

We investigated whether heart rate (HR)-derived parameters are accurate performance predictors in endurance recreational runners. One hundred thirty recreational athletes completed an incremental running test (4´running + 1´rest). After each stage, we recorded HR, % of maximum HR (%HRmax), and blood lactate. We also assessed HR after each recovery period, and calculated lactate and HR recovery thresholds and HR deflection point. We tested these parameters for associations with running performance, as measured by peak treadmill speed (PTS) and personal best International Association of Athletics Federations (IAAF) score. The %HRmax at 14.5 km·h^?1 correlated with PTS (r = ?0.92), and IAAF score (rho = ?0.80). The magnitudes of the correlations of lactate-related parameters with PTS (|r| = 0.84 to 0.86) or IAAF score (|rho| = 0.70 to 0.77) in absolute values were slightly lower. The correlations detected between other HR-derived parameters and running performance were weaker (|r or rho| = 0.24 to 0.70). Regression models identified %HRmax at 14.5 km·h^?1 as the strongest predictor of both PTS (β = ?0.72) and IAAF score (β = ?0.72). Consequently, tests based on %HRmax may provide a non-invasive and inexpensive alternate method for predicting the performance of these athletes.  相似文献   

Leveraging community sport organizations to promote community capacity: Strategic outcomes,challenges, and theoretical considerations     

Gareth J. Jones  Michael B. Edwards  Jason N. Bocarro  Kyle S. Bunds  Jordan W. Smith 《Sport Management Review》2018,21(3):279-292

Community sport organizations (CSOs) provide valuable contexts for promoting community development. These initiatives are most effective when they involve local stakeholders in the process of development. A key first step to achieving this objective is building community capacity, defined as local stakeholders’ skills, knowledge, and resources that may be leveraged for change. Interestingly, despite this conceptual importance, few researchers have focused on capacity building in the sport context. This has limited the theoretical advancement of community capacity theory as it relates to CSOs and community development. Using a qualitative case study approach, the authors analyze the outcomes and challenges of implementing community capacity building strategies in an American CSO, and draw on the empirical data to contribute to this theoretical conversation. Interviews, participant observation, and document analysis were used to generate data, and deductive techniques were used for thematic analysis. The results highlight the outcomes of the capacity building strategies and challenges associated with implementation. In addition, the conclusion focuses on theoretical contributions to community capacity theory, namely the role of sport in facilitating inter-community relations across social groups and the link with process models of organizational capacity.  相似文献   

Decrements in knee extensor and flexor strength are associated with performance fatigue during simulated basketball game-play in adolescent,male players     

Aaron T Scanlan  Jordan L Fox  Nattai R Borges  Anne Delextrat  Tania Spiteri  Vincent J Dalbo 《Journal of sports sciences》2018,36(8):852-860

This study quantified lower-limb strength decrements and assessed the relationships between strength decrements and performance fatigue during simulated basketball. Ten adolescent, male basketball players completed a circuit-based, basketball simulation. Sprint and jump performance were assessed during each circuit, with knee flexion and extension peak concentric torques measured at baseline, half-time, and full-time. Decrement scores were calculated for all measures. Mean knee flexor strength decrement was significantly (P < 0.05) related to sprint fatigue in the first half (R = 0.65), with dominant knee flexor strength (R = 0.67) and dominant flexor:extensor strength ratio (R = 0.77) decrement significantly (P < 0.05) associated with sprint decrement across the entire game. Mean knee extensor strength (R = 0.71), dominant knee flexor strength (R = 0.80), non-dominant knee flexor strength (R = 0.75), mean knee flexor strength (R = 0.81), non-dominant flexor:extensor strength ratio (R = 0.71), and mean flexor:extensor strength ratio (R = 0.70) decrement measures significantly (P < 0.05) influenced jump fatigue during the entire game. Lower-limb strength decrements may exert an important influence on performance fatigue during basketball activity in adolescent, male players. Consequently, training plans should aim to mitigate lower-limb fatigue to optimise sprint and jump performance during game-play.  相似文献   

Influence of regression model and initial intensity of an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and running performance

Abstract

This study investigated the influence of the regression model and initial intensity during an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and performance in elite-standard runners. Twenty-three well-trained runners completed a discontinuous incremental running test on a treadmill. Speed started at 9 km · h^?1 and increased by 1.5 km · h^?1 every 4 min until exhaustion, with a minute of recovery for blood collection. Lactate–speed data were fitted by exponential and polynomial models. The lactate threshold was determined for both models, using all the co-ordinates, excluding the first and excluding the first and second points. The exponential lactate threshold was greater than the polynomial equivalent in any co-ordinate condition (P < 0.001). For both models, the lactate threshold was lower when all co-ordinates were used than when the first and the first and second points were excluded (P < 0.001). 10-km race pace was correlated with both the exponential and polynomial lactate thresholds for all the co-ordinate conditions (r ≥ 0.75, P < 0.001 and r ≥ 0.56, P < 0.05, respectively). The results suggest that the exponential lactate threshold should be used instead of the polynomial equivalent since it is more strongly associated with performance and is independent of the initial intensity of the test.  相似文献   

Boy Trouble: Rhetorical framing of boys' underachievement   总被引：1，自引：1，他引：1  

Jordan J. Titus 《Discourse: Studies in the Cultural Politics of Education》2004,25(2):145-169

This article examines discourse in the United States used to socially construct an “underachieving boys” moral panic. Employing discourse analysis I examine the adversarial rhetoric of claims-makers and the frames they deploy to undermine alternative and conflicting accounts (of females as disadvantaged) and to forestall any challenges to the scientific authority of their own (biological essentialist) account of crisis. I illustrate how this discourse adapts the rhetorical frame of gender equity from the discourse it politically opposes, and uses it to legitimate its own goals. I find that the framing of innocent victimized boys as scientific “truth” is aligned with a broader masculinity politics that blames certain “folk devils”, and a synchronic moral panic about fearsome (black) male youth. I conclude by considering the success of this moral panic as evidenced by changes in educational policies and practices in the United States.  相似文献

A simple microscopy assay to teach the processes of phagocytosis and exocytosis     

Gray R  Gray A  Fite JL  Jordan R  Stark S  Naylor K 《CBE life sciences education》2012,11(2):180-186

Phagocytosis and exocytosis are two cellular processes involving membrane dynamics. While it is easy to understand the purpose of these processes, it can be extremely difficult for students to comprehend the actual mechanisms. As membrane dynamics play a significant role in many cellular processes ranging from cell signaling to cell division to organelle renewal and maintenance, we felt that we needed to do a better job of teaching these types of processes. Thus, we developed a classroom-based protocol to simultaneously study phagocytosis and exocytosis in Tetrahymena pyriformis. In this paper, we present our results demonstrating that our undergraduate classroom experiment delivers results comparable with those acquired in a professional research laboratory. In addition, students performing the experiment do learn the mechanisms of phagocytosis and exocytosis. Finally, we demonstrate a mathematical exercise to help the students apply their data to the cell. Ultimately, this assay sets the stage for future inquiry-based experiments, in which the students develop their own experimental questions and delve deeper into the mechanisms of phagocytosis and exocytosis.  相似文献
