Precursors to the development of flexible expertise: Metacognitive self-evaluations as antecedences and consequences in adult learning     

Damian P. Birney  Jens F. Beckmann  Robert E. Wood 《Learning and individual differences》2012,22(5):563-574

The current study investigates a conceptualization of flexible expertise as it relates to adult learning within the context of management and leadership training. Three research domains and their relation to metacognitive outcomes are integrated: 1) individual differences in abilities, personality, and mindsets, 2) deliberate practice and routine expertise, and 3) self-regulatory processes. The theoretical focus of the research is on the extent to which metacognitive self-evaluations around person- and management-specific concepts taught during training may act as precursors to flexible expertise. We asked 172 mid-level managers to provide evaluations of concept importance (antecedent), behavioral change (proximal consequence), and impact on job performance (distal consequence) resulting from knowledge acquired during the course of training. A series of hierarchical linear modeling analyses unveil a constellation of core personality characteristics, mindsets, and deliberative processing experiences that together interact to predict metacognitive self-evaluation of impactful training. Our results suggest support for our contention that flexible expertise is a context appropriate, balanced cluster of learning oriented, self-regulatory, and metacognitive processes that moderate and mediate the application of abilities and previously acquired knowledge to problem solution, future knowledge acquisition, and ultimately effective leadership.  相似文献   

Central processing energetic factors mediate impaired motor control in ADHD combined subtype but not in ADHD inattentive subtype     

Egeland J  Ueland T  Johansen S 《Journal of learning disabilities》2012,45(4):361-370

Participants with attention-deficit/hyperactivity disorder (ADHD) are often impaired in visuomotor tasks. However, little is known about the contribution of modal impairment in motor function relative to central processing deficits or whether different processes underlie the impairment in ADHD combined (ADHD-C) versus ADHD inattentive (ADHD-I) subtype. The present study analyzes performance on the Visual Motor Integration Test relative to less effortful motor tests as well as on measures of energetics. Both ADHD groups showed evidence of impaired motor function on both visual-motor integration (VMI) and the less effortful motor tests. The ADHD-C group performed below the ADHD-I group on VMI, but their performance correlated highly with the measures of the energetic pools of arousal and effort. Different mechanisms may underlie impaired fine motor skills in ADHD. Central processing deficits contribute significantly to the deficit of ADHD-C but do not explain the motor impairment in ADHD-I.  相似文献   

Affordances and Constraints of Using the Socio-Political Debate for Authentic Summative Assessment     

Jens Anker-Hansen  Maria Andrée 《International Journal of Science Education》2013,35(15):2577-2596

This article reports from an empirical study on the affordances and constraints for using staged socio-political debates for authentic summative assessment of scientific literacy. The article focuses on conditions for student participation and what purposes emerge in student interaction in a socio-political debate. As part of the research project, a socio-political debate was designed for assessing student competences of scientific literacy in classroom practices. The debate centred on a fictive case about a lake where a decline in the yield of fish had been established. The students were assigned the task of participating in the debate from appointed roles as different stakeholders. Data were collected with video recordings of the enacted student debates. Student participation was analysed with the theoretical framework of communities of practice. The results show that multiple conflicting purposes of the socio-political debate as an assessment task emerged. The emergent purposes were (1) putting scientific knowledge on display versus staying true to one's role, (2) putting scientific knowledge on display versus expressing social responsibility, (3) putting scientific knowledge on display versus winning the debate, and (4) using sources tactically versus using sources critically. As these purposes emerged in classroom practice, tensions between different ways of enacting participation in the debates became manifest. Based on these findings, this article discusses the affordances and constraints for using a socio-political debate for classroom-based assessment of scientific literacy and argumentation in terms of validity, reliability and affordability.  相似文献

Bayesian statistical methods are becoming ever more popular in applied and fundamental research. In this study a gentle introduction to Bayesian analysis is provided. It is shown under what circumstances it is attractive to use Bayesian estimation, and how to interpret properly the results. First, the ingredients underlying Bayesian methods are introduced using a simplified example. Thereafter, the advantages and pitfalls of the specification of prior knowledge are discussed. To illustrate Bayesian methods explained in this study, in a second example a series of studies that examine the theoretical framework of dynamic interactionism are considered. In the Discussion the advantages and disadvantages of using Bayesian statistics are reviewed, and guidelines on how to report on Bayesian statistics are provided.  相似文献   

Question formulation skills training using a novel rubric with first-year medical students     

Jonathan Eldredge  Melissa A. Schiff  Jens O. Langsjoen  Roger N. Jerabek 《Journal of the Medical Library Association》2021,109(1):68

Objective:The authors used an assessment rubric to measure medical students'' improvement in question formulation skills following a brief evidence-based practice (EBP) training session conducted by a health sciences librarian.Method:In a quasi-experimental designed study, students were assessed using a rubric on their pre-instructional skills in formulating answerable EBP questions, based on a clinical scenario. Following their training, they were assessed using the same scenario and rubric. Student pre- and post-test scores were compared using a paired t-test.Results:Students demonstrated statistically significant improvement in their question formulation skills on their post-instructional assessments. The average score for students on the pre-test was 45.5 (SD 11.1) and the average score on the post-test was 65.6 (SD 5.4) with an average increase of 20.1 points on the 70-point scale, p<0.001.Conclusion:The brief instructional session aided by the rubric improved students'' performance in question formulation skills.  相似文献   

Paper-based colorimetric enzyme linked immunosorbent assay fabricated by laser induced forward transfer     

Ioannis N. Katis  Judith A. Holloway  Jens Madsen  Saul N. Faust  Spiros D. Garbis  Peter J. S. Smith  David Voegeli  Dan L. Bader  Robert W. Eason  Collin L. Sones 《Biomicrofluidics》2014,8(3)

We report the Laser Induced Forward Transfer (LIFT) of antibodies from a liquid donor film onto paper receivers for application as point-of-care diagnostic sensors. To minimise the loss of functionality of the active biomolecules during transfer, a dynamic release layer was employed to shield the biomaterial from direct exposure to the pulsed laser source. Cellulose paper was chosen as the ideal receiver because of its inherent bio-compatibility, liquid transport properties, wide availability and low cost, all of which make it an efficient and suitable platform for point-of-care diagnostic sensors. Both enzyme-tagged and untagged IgG antibodies were LIFT-printed and their functionality was confirmed via a colorimetric enzyme-linked immunosorbent assay. Localisation of the printed antibodies was exhibited, which can allow the creation of complex 2-d patterns such as QR codes or letters for use in a final working device. Finally, a calibration curve was determined that related the intensity of the colour obtained to the concentration of active antibodies to enable quantitative assessment of the device performance. The motivation for this work was to implement a laser-based procedure for manufacturing low-cost, point-of-care diagnostic devices on paper.  相似文献   

Learning about earthquakes: getting serious about authenticity in computer-supported learning     

Nelson Baloian  Jose A. Pino  Jens Hardings 《Interactive Learning Environments》2013,21(3):285-302

The discovery or re-construction of scientific explanations and understanding based on experience is a complex process, for which school learning often uses shortcuts. On the basis of the example of analyzing real seismic measurements, we propose a computer-facilitated collaborative learning scenario which meets many of the requirements for authentic learning, knowledge construction, and collaboration. The implementation of the learning environment called SeisModes is based on a general platform for supporting collaborative modeling activities. SeisModes provides a tool to allow students collaboratively learn about earthquakes and thus reduce the fears they might have concerning them. First formal evaluations showed the approach motivates students.  相似文献   

Einfluss unterschiedlicher Motive auf den zeitlichen Umfang ehrenamtlichen Engagements in Sportvereinen     

Jun.-Prof. Jens Flatau  Prof. Eike Emrich  Prof. Christian Pierdzioch 《Sportwissenschaft》2014,44(1):10-24

In the social science literature, various motives for volunteering are discussed. However, so far little is known about the specific relationship between these motives and the time invested in voluntary work. Hypotheses derived from consumer goods theory concerning this association were examined. The results show (1) that altruistic motives increase the amount of engagement, and (2) that selfishly motivated volunteerism is an experience good.  相似文献   

Activity profile and physiological demands of top-class soccer assistant refereeing in relation to training status     

Peter Krustrup  Magni Mohr  Jens Bangsbo 《Journal of sports sciences》2013,31(11):861-871

To determine the movement patterns and physiological demands of top-class soccer assistant referees, we performed computerized time-motion analysis and measured heart rate and blood lactate concentration in 15 assistant referees during 22 competitive matches in the top Danish league. To relate match performance to the physical capability of the assistant referees, they performed a 3 2 30 m sprint protocol before and after matches and a laboratory treadmill test within 3 weeks of the games. The mean total distance covered by the top-class assistant referees was 7.28 (range 5.78-8.16) km, of which 1.15 (0.86-1.44) km was high-intensity running and 1.16 (0.12-2.34) km was sideways running. The amount of high-intensity running during a game was correlated with performance of repeated sprints (r = 0.80, P ? 0.05). Mean heart rate was 137 (117-159) beats · min^-1 , corresponding to 73% (60-88%) of maximal heart rate and 65% (53-80%) of maximal oxygen uptake. Blood lactate concentration was 4.7 (1.6-11.0) and 4.8 (1.1-13.7) mmol · l -1 after the first and second half, respectively. Sprinting performance was poorer (P ? 0.05) after than before the games. The peak distance to the offside line was greater (P ? 0.05) in the second than the first half (7 - 1 vs 5 - 0 m). Our results show that: (1) top-class assistant soccer refereeing is characterized by brief intense bouts of forward and sideways running interspersed with long periods of low activity; (2) top-class soccer assistant referees have moderate aerobic energy production during games with episodes of high aerobic and anaerobic energy turnover; (3) assistant referees' performance of repeated sprints correlates with the amount of high-intensity running performed in a game; and (4) sprint performance decreases towards the end of a game, which appears to affect assistant referees' ability to keep up with play.  相似文献
