Threshold concepts in higher education: a synthesis of the literature relating to measurement of threshold crossing

In relation to teaching and learning approaches that improve student learning outcomes, threshold concepts have generated substantial interest in higher education. They have been described as ‘portals’ that lead to a transformed way of understanding or thinking, enabling learners to progress, and have been enthusiastically adopted to inform teaching approaches and curriculum design. A growing body of literature has critiqued the relevance and applicability of the threshold concept theory and identified threshold concepts relevant to specific disciplines. More recent research has identified how students cross these thresholds and provided measures of the successful acquisition of threshold concepts. This literature synthesis critiques existing evidence on threshold crossing and acquisition to provide a succinct and informative overview of the outcomes to date. Key questions relevant to educators and researchers investigating whether students acquire the threshold concepts associated with their teaching, arose from the literature synthesis. These were: whether or not threshold crossing can be measured; how variation in student learning can be addressed during measurement; tools that can be used for measuring threshold crossing; whether the way units or concepts are taught should alter prior to measurement, and the challenges and limitations of measuring threshold crossing.  相似文献   

Effects of a Brief Mindfulness Based Group Intervention On College Students     

Jason Parcover  Mary Jo Coiro  Esther Finglass  Emily Barr 《Journal of College Student Psychotherapy》2018,32(4):312-329

Increases in the number of college students seeking mental health services require counseling centers to explore innovative strategies to provide effective and efficient treatments. Group interventions offer an alternative to traditional individual counseling, allowing centers to serve more students with fewer clinical staff (Burlingame et al., 2016). Of current group modalities, mindfulness-based interventions (MBIs) have been growing in popularity as an effective approach for addressing college students’ increasingly complex needs. This study describes the evaluation of a three-session mindfulness-based intervention on students’ mindfulness, symptoms, and stress. Compared to a comparison group of 109 students not seeking counseling center services, 78 students who received the intervention reported increased mindfulness, and decreased symptoms of depression, anxiety, and stress at the end of the group. Furthermore, improvements in mindfulness mediated intervention effects on symptoms of depression and anxiety. These gains were generally maintained 3 weeks later. These findings support the benefits of brief group interventions for college students. Suggestions for modifications to the intervention and for future research are discussed.  相似文献   

The effects of limb dominance and a short term,high intensity exercise protocol on both landings of the vertical drop jump: implications for the vertical drop jump as a screening tool     

Enda F. Whyte  Patrick Kennelly  Oliver Milton  Chris Richter  Siobhán O’Connor  Kieran A. Moran 《Sports biomechanics / International Society of Biomechanics in Sports》2018,17(4):541-553

The effectiveness of vertical drop jumps (VDJs) to screen for non-contact ACL injuries is unclear. This may be contributed to by discrete point analysis, which does not evaluate patterns of movement. Also, limited research exists on the second landing of VDJs, potential lower limb performance asymmetries and the effect of fatigue. Statistical parametric mapping investigated the main effects of landing, limb dominance and a high intensity, intermittent exercise protocol (HIIP) on VDJ biomechanics. Twenty-two male athletes (21.9 ± 1.1 years, 180.5 ± 5.5 cm, 79.4 ± 7.8 kg) performed VDJs pre- and post-HIIP. Repeated measures ANOVA identified pattern differences during the eccentric phases of the first and second landings bilaterally. The first landing displayed greater (internal) knee flexor (η² = 0.165), external rotator (η² = 0.113) and valgus (η² = 0.126) moments and greater hip (η² = 0.062) and knee (η² = 0.080) flexion. The dominant limb generated greater knee flexor (η² = 0.062), external rotator (η² = 0.110) and valgus (η² = 0.065) moments. The HIIP only had one effect, increased thoracic flexion relative to the pelvis (η² = 0.088). Finally, the dominant limb demonstrated greater knee extensor moments during the second landing (η² = 0.100). ACL injury risk factors were present in both landings of VDJs with the dominant limb at potentially greater injury risk. Therefore, VDJ screenings should analyse both landings bilaterally.  相似文献   

New insight for activity intensity relativity,metabolic expenditure during object projection skill performance     

Ryan S. Sacko  Kerry McIver  Ali Brian  David F. Stodden 《Journal of sports sciences》2018,36(21):2412-2418

This study examined the metabolic cost (METs) of performing object projection skills at three practice trial intervals (6, 12, and 30 seconds). Forty adults (female n = 20) aged 18–30 (M = 23.7 ± 2.9 years) completed three, nine-minute sessions of skill trials performed at 6, 12, and 30 second intervals. Participants performed kicking, throwing and striking trials in a blocked schedule with maximal effort. Average METs during each session were measured using a COSMED K4b2. A three (interval condition) X two (sex) ANOVA was conducted to examine differences in METs across interval conditions and by sex. Results indicated a main effect for interval condition (F(5,114) = 187.02, p < .001, η² = 0.76) with decreased interval times yielding significantly higher METs [30 sec = 3.45, 12 sec = 5.68, 6 sec = 8.21]. A main effect for sex (F(5, 114) = 35.39, p < .001, η² = 0.24) also was found with men demonstrating higher METs across all intervals. At a rate of only two trials/min, participants elicited moderate physical activity, with 12 and 6-second intervals exhibiting vigorous PA. Demonstrating MVPA during the performance of object projection skill performance has potential implications for PA interventions.  相似文献   

Acute kinematics changes in marathon runners using different footwear     

Tania Socorro Amorim Soares  Federico Pizzuto  Rui Manuel Garganta  João Paulo Vila-Boas  Mario Casimiro da Anunciação Paiva 《Journal of sports sciences》2018,36(7):766-770

The effects of running with or without shoes on injury prevention have been extensively studied, and several investigations have assessed biomechanical differences between them. However, findings are not consensual and further insights on biomechanical load associated with differently shod or barefoot conditions may be needed. This study aimed to observe if habitually shod marathon runners show acute alterations when running barefoot or with minimalist shoes, and to determine whether the running kinematical adaptations of wearing minimalist shoes were similar to barefoot running. Twelve male marathon runners ran on the treadmill at their average marathon pace in different footwear conditions: habitual running shoes, minimalist shoes, and barefoot. High-resolution infrared cameras and visual 3D software were used to assess kinematic data. The following parameters were studied: foot strike angle, cycle time, stance time, normalized stride length, hip, knee, and ankle angular position at initial contact, and their respective range-of-motion (ROM) during stance phase. Contrary to the expectations, it was found that highly trained habitually shod elite marathon runners changed their lower limb kinematic pattern both when running barefoot or wearing minimalist shoes. Minimalist shoes showed a trend towards intermediate biomechanical effects between running with and without shoes.  相似文献

Articulating and Utilizing Communication Student Learning Outcomes in Community Colleges     

Megan Tucker  Kerry Byrnes-Loinette  David Bodary 《Community College Journal of Research & Practice》2018,42(3):218-221

Academia in the United States stands face-to-face with the constant call for greater levels of assessment and accountability. Academics question whether our students are learning what they’re taught? Are they able to secure employment upon completing their education? Are they prepared to be active, productive citizens in society? Community colleges provide education to those who may typically not have the opportunity to attend an institution of higher education. A foundation of any assessment process is the articulation of the core learning outcomes. It is from this foundation, then, that community college faculty can start assessing the effectiveness of teaching and curricular design. The present investigation details a project that focused on creating discipline-specific student learning outcomes and how these outcomes can be utilized to aligning learning outcomes and mapping to curriculum. Communication studies faculty can utilize the learning outcomes to strengthen and clarify curriculum, demonstrate the acquisition of competencies, and improve departmental offerings.  相似文献   

“You have to do something beyond containing”: developing inclusive systems in a partnership of primary schools     

Jo Rose  Alex Stanforth  Gwen Gilmore  Jill Bevan-Brown 《Emotional and Behavioural Difficulties》2018,23(3):270-283

Reducing fixed term exclusions (FTE) in primary schools is a difficult proposition. This research discusses how a partnership of primary schools developed more inclusive systems to support students previously given FTEs for disciplinary purposes. Longitudinal data from interviews and documentary sources trace the development of an approach amongst primary schools with previously high levels of FTE. The process of developing a model of transferred inclusion (TI) within the partnership led to schools changing practices around behaviour management, thus developing more inclusive systems. The paper elaborates on partnership work around the TI project that opened up discussion and questioning of practice around behaviour, leading to schools thinking about their systemic practice. The benefits of TI, therefore, were a prompt for development, rather than just an intervention to reduce exclusions. Changes in practice supported through the TI process lead to claims that substantive change would not have happened without the TI project.  相似文献   

Information-governing dynamics of attacker–defender interactions in youth rugby union

Abstract

Previous work on dynamics of interpersonal interactions in 1 vs. 1 sub-phases of basketball has identified changes in interpersonal distance between an attacker and defender as a potential control parameter for influencing organizational states of attacker–defender dyads. Other studies have reported the constraining effect of relative velocity between an attacker and defender in 1 vs. 1 dyads. To evaluate the relationship between these candidate control parameters, we compared the impact of both interpersonal distance and relative velocity on the pattern-forming dynamics of attacker–defender dyads in the sport of rugby union. Results revealed that when interpersonal distance achieved a critical value of less than 4 m, and relative velocity values increased or were maintained above 1 m · s^?1, a successful outcome (i.e. clean attempt) for an attacker was predicted. Alternatively, when values of relative velocity suddenly decreased below this threshold, at the same critical value of interpersonal distance, a successful outcome for the defender was predicted. Data demonstrated how the coupling of these two potential, nested control parameters moved the dyadic system to phase transitions, characterized as a try or a tackle. Observations suggested that relative velocity increased its influence on the organization of attacker–defender dyads in rugby union over time as spatial proximity to the try line increased.  相似文献   

Improvement of cellular health indicators and muscle quality in older women with different resistance training volumes

ABSTRACT

The main purpose of this study was to compare the effects of resistance training (RT) performed with different training volumes on phase angle (PhA), body water components, and muscle quality (MQ) in untrained older adult women. A second purpose was to assess the relationship between PhA and MQ. Sixty-two older adult women (68.6 ± 5.0 years, 65.2 ± 13.3 kg, 156.1 ± 6.2 cm) were randomly assigned into one of the three groups: two training groups performed either 1 set (G1S) or 3 sets (G3S), or a control group (CG). Body water components and PhA were estimated by bioelectrical impedance (BIA). MQ was determined by dividing skeletal muscle mass estimated by dual-energy absorptiometry (DXA) by total muscle strength from three exercises. After the intervention period, both training groups demonstrated improvements (P < 0.05) when compared with CON for intracellular water, total body water, PhA, and MQ. These results suggest that RT can improve PhA, body water components, and MQ after 12 weeks of RT in untrained older women, regardless of training volume. Furthermore, changes in MQ were positively correlated with changes in PhA (r = 0.60, P < 0.01).  相似文献
