浅谈暗夜AC、风德内战的细节     

Eric 《电子竞技》2010,(1):64-68

在魔兽发展的7年时间里，暗夜内战经历了首发白虎暴海量HT（女猎手）开矿对拼的时期，也曾经流行DH（恶魔猎手）、Naga（娜迦海妖）速熊到80人口互拍一波定胜负，到现在衍生出的改进版AC（弓箭手）风德内战三英雄的过程，每一次的战术改变都让我们深深地体会到了魔兽的求变之路是如此的迫切、如此的惊喜不断。  相似文献

Understanding the role of shaft stiffness in the golf swing   总被引：3，自引：3，他引：0  

Sasho James MacKenzie  Eric J. Sprigings 《Sports Engineering》2009,12(1):13-19

Theoretically, shaft stiffness can alter shot distance by increasing clubhead speed or altering clubhead orientation at impact. A 3D forward dynamics model of a golfer and flexible club simulated the downswing. A genetic algorithm optimized the coordination of the model’s muscles (four torque generators) to maximize clubhead speed. The maximum torque output and maximum rate of torque development from the torque generators were varied to simulate the swing of golfers that generate different clubhead speeds. Four shafts of varying stiffness (flexible, regular, stiff, and completely rigid) were entered into these simulations to examine the role that shaft flexibility had on clubhead speed and orientation at impact. Shaft stiffness was found to have a meaningful effect only on clubhead orientation (dynamic loft and dynamic close) at impact. There was no evidence to support the premise that matching the stiffness properties of the shaft with the golfer would improve clubhead speed.  相似文献   

A method for personalising the blade size for competitors in flatwater kayaking     

Eric Sprigings  Peter McNair  Grant Mawston  David Sumner  Mark Boocock 《Sports Engineering》2006,9(3):147-153

The intent of this project was to explore the feasibility of personalising the paddle blade size for individual flatwater kayakers based on their power output profiles. Twelve elite male kayakers performed on a kayak ergometer at the same intensity and resistance that they would normally experience while paddling at race pace for 500 m on the water. The kayak ergometer was instrumented so that power profiles could be determined from the instantaneous force and velocity of the representative centre point of the paddle blade. From the power profile information, the researchers calculated a personalised blade size that was expected to improve performance for those kayakers differing more than 5% from the calculated ‘ideal’ size. For the elite kayakers studied, it was recommended that seven of the paddlers should increase their blade size by approximately 5–10%. For the remaining five paddlers, the results indicated that their current blade sizes were within the expected measurement error of their predicted ideal value and should be retained. It is anticipated that this research will provide the theoretical rationale for elite kayakers to see the need to personalise their blade size based on their own muscle power profiles.  相似文献   

Changing classroom culture,curricula, and instruction for proof and proving: how amenable to scaling up,practicable for curricular integration,and capable of producing long-lasting effects are current interventions?     

Elena Nardi  Eric Knuth 《Educational Studies in Mathematics》2017,96(2):267-274

This paper is a commentary on the classroom interventions on the teaching and learning of proof reported in the seven empirical papers in this special issue. The seven papers show potential to enhance student learning in an area of mathematics that is not only notoriously difficult for students to learn and for teachers to teach, but also critically important to knowing and doing mathematics. Although the seven papers, and the intervention studies they report, vary in many ways—student population, content domain, goals and duration of the intervention, and theoretical perspectives, to name a few—they all provide valuable insight into ways in which classroom experiences might be designed to positively influence students’ learning to prove. In our commentary, we highlight the contributions and promise of the interventions in terms of whether and how they present capacity to change the classroom culture, the curriculum, or instruction. In doing so, we distinguish between works that aim to enhance students’ preparedness for, and competence in, proof and proving and works that explicitly foster appreciation for the need and importance of proof and proving. Finally, we also discuss briefly the interventions along three dimensions: how amenable to scaling up, how practicable for curricular integration, and how capable of producing long-lasting effects these interventions are.  相似文献

A praxeological perspective for the design and implementation of a digital role-play game     

Eric Sanchez  Réjane Monod-Ansaldi  Caroline Vincent  Sina Safadi-Katouzian 《Education and Information Technologies》2017,22(6):2805-2824

This paper draws on an empirical work dedicated to discussing a theoretical model for design-based research. The context of our study is a research project for the design, the implementation and the analysis of Insectophagia, a digital role-play game implemented in secondary schools. The model presented in this paper aims at conceptualizing researchers’ and practitioners’ relationships with the notion that knowledge development takes place at a meta-didactical level when the participants develop a shared practice and a shared discourse on practice (a common praxeology). This is done through collaboration and teacher-centered design of innovative learning settings. This model emerges from a double approach: (1) a literature review on collaborative research in education and, (2) an analysis of the verbal interactions of practitioners and researchers involved in the project. The study emphasizes the development of knowledge among participants. It also emphasizes the importance of knowledge brokering for filling the gap between research and practice and thus, for the adoption of digital technology by practitioners.  相似文献   

A Behavioral Approach to Building Cognitive Foundations for Effective Thought and Action     

Eric Pappas  Jesse Pappas 《Innovative Higher Education》2011,36(5):359-372

This research documents the process and results of an approach to teaching university undergraduates intentional self-development skills designed to promote self-generated goals, routines, and lifestyle choices. These skills may provide effective behavioral foundations for developing metacognitive awareness, intentionality, and individual well-being. The results of six original behavioral interventions, implemented in two James Madison University courses, provide initial support for the effectiveness of these instructional methodologies.  相似文献
