Instructional design for advanced learners: Establishing connections between the theoretical frameworks of cognitive load and deliberate practice

Cognitive load theory (CLT) has been successful in identifying instructional formats that are more effective and efficient than conventional problem solving in the initial, novice phase of skill acquisition. However, recent findings regarding the “expertise reversal effect” have begun to stimulate cognitive load theorists to broaden their horizon to the question of how instructional design should be altered as a learner's knowledge increases. To answer this question, it is important to understand how expertise is acquired and what fosters its development. Expert performance research, and, in particular, the theoretical framework of deliberate practice have given us a better understanding of the principles and activities that are essential in order to excel in a domain. This article explores how these activities and principles can be used to design instructional formats based on CLT for higher levels of skills mastery. The value of these formats for e-learning environments in which learning tasks can be adaptively selected on the basis of online assessments of the learner's level of expertise is discussed. In their preparation of this article, the first and last authors were supported by an Internationalization grant from the Netherlands Organization for Scientific Research (NWO, The Hague, project number 411-01-010).

The influence of achievement motivation and chess-specific motivation on deliberate practice

Although the importance of high motivation to engage in deliberate practice has been acknowledged, no research has directly tested this hypothesis. Therefore, the present study examined this relation in adolescent elite chess players by means of a questionnaire. In addition, to provide an explanation for dropout among promising chess players, differences in motivation between persistent and dropout chess players were analyzed. Competitiveness and the will to excel proved to be predictors of investments in deliberate practice. Moreover, achievement motivation and chess-specific motivation differed to a certain extent between persisters and dropouts. Our results suggest that motivation to engage in deliberate practice not only contains elements of the will to improve performance, but also of the will to attain exceptional levels of performance.     

保山市隆阳区白花蛇舌草生境的群落学研究

通过保山市隆阳区白花蛇舌草植物群落的样地调查,发现调查区共记载维管植物28科53属59种(含亚种、变种)。植物属地理成分分析表明,白花蛇舌草生境的植物区系成分较为复杂,分布类型多样,其中泛热带分布、北温带分布、东亚分布、旧世界温带分布、热带亚洲至热带非洲分布、旧世界热带分布在群落中占有重要地位。群落成分分析表明,植物组成种类复杂,类型十分丰富。生活型谱和盖度系数分析显示,该群落以地面芽植物和高位芽植物为主,反映出其生境属于亚热带森林区域气候。白花蛇舌草适合酸性,有机质丰富,中等湿度的土壤,中、弱等的光照和亚热带温凉湿润的气候的生境条件。
