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 conditions for establishment of an ideological dilemma: antagonistic discourses and over-determined identity in school music teaching

This article presents an analysis of video documentation of music teaching in Swedish schools. The article is based on a larger research project, funded by The Swedish Research Council, the purpose of which has been to study how market aesthetics and students’ everyday culture are applied to the teaching of music. The introduction presents a background for the study's focus on music teaching in relation to issues of student influence. Next, the theoretical and methodological starting points are presented. With discourse psychological microanalysis as a point of departure, the ideological dilemma that has emerged in the analysis of the videos is then identified and discussed. In addition, the different types of subject positions contained in the studied discursive practice are problematized. The article concludes with a discussion of a number of factors that contribute to the establishment of ideological dilemmas in school practitioners of music education.     

The Scientific Study of Expert Levels of Performance: general implications for optimal learning and creativity 1

Recent research in many different domains of expertise has shown that the large differences in performance between experts and novices are frequently reproducible under standardized conditions and can often be captured with representative tasks in the laboratory. Furthermore, these differences in performance are predominantly mediated by complex skills acquired over a decade, as a result of high daily levels of activities which are specially designed'to improve performance (deliberate practice). The effects of extended deliberate practice are remarkably far‐reaching and include physiological adaptations and qualitative changes in performance mediated by acquired cognitive skills. Most importantly, expert performers have acquired mental representations that allow them to plan and reason about potential courses of action and these representations also allow experts to monitor their performance, thus providing critical feedback for continued complex learning. The study of elite performance also reveals how acquired representation and skills provide the necessary tools for the ultimate eminent achievement, namely the generation of creative innovations to the domain.

     

In search of the loci for sex differences in throwing: the effects of physical size and differential recruitment rates on high levels of dart performance

Contemporary accounts of sex differences in perceptual-motor performance differ in their emphasis on nature and nurture. Study 1 examined the effect of extensive training on one of the largest sex differences, namely accuracy in dart throwing, and found that physical differences in height and reach could not explain sex differences in regional/national level dart players. Study 2 rejected accounts of sex differences based on participation rates by showing that male players recruited from a relatively small pool of club players were superior to the best female players selected from a much larger pool at the international level. Alternative accounts of the source of sex differences in darts, based on male and female players' differential development and practice histories, are discussed.     

An expert performance approach to the study of individual differences in self-regulated learning activities in upper-level college students

One of the hallmarks of adolescent and adult development of expert performance is its self regulation. This paper reviews different approaches to assessing the use of self-regulated learning (SRL) strategies in high-school and college students and their ability to predict academic performance. The current study assesses the use of SRL strategies with interviews and diaries and their relation to grade point average (GPA) in sixty upper-level college students majoring in science. Their diaries revealed that students with high, average, and low GPAs (assessed before the start of the semester) differed in overall use of SRL strategies and in the use of particular strategies during specific weeks. Methods of assessing and understanding differences in adult self-regulation and subsequent academic performance are evaluated and discussed.     

Generalizable aspects of the development of expertise in ballet across countries and cultures: a perspective from the expert-performance approach

The expert-performance approach guided the collection of survey data on the developmental history of elite professional ballet dancers from three different countries/cultures (USA, Mexico, and Russia). The level of ballet expertise attained by age 18 was found to be uniquely predicted by only two factors, namely the total number of accumulated hours of dance practice through age 17 and the age of first having the “idea of becoming a professional dancer.” Older starting ages were associated with a more rapid increase of weekly training, so starting ages were not correlated with amount of practice accumulated at age 17 or attained ballet performance by age 18. Different detailed developmental paths leading to elite ballet performance are described and their theoretical implications discussed.

Motor skills,attention and academic achievements. An intervention study in school years 1–3

The aim was to study effects of an extension of physical education and motor training on motor skills, attention and cognition during a period of three years. The study has two intervention groups (n = 152) that have physical activity and motor training one lesson every school day and one control group (n = 99) that has the school's ordinary physical education two lessons per week. The method is hypothetic‐deductive. The results confirm the hypothesis that children's motor skills improve with extended physical activity and motor training. The hypothesis that children's attention will improve cannot be confirmed. Although pupils in intervention groups have better attention in school year 2 than pupils in the control group, the differences do not remain in school year 3. The third hypothesis concerning academic achievements is confirmed by several results in Swedish and mathematics. The MUGI observation programme was found to be useful both as a screening and as a pedagogic instrument.     

Physiological and metabolic responses of wheelchair athletes in different racing classes to prolonged exercise

The aims of this study were to examine and compare selected physiological and metabolic responses of wheelchair athletes in two paraplegic racing classes [T3: n?=?8 (lesion levels T1–T7; paraplegics); T4: n?=?9 (lesion levels below T7; paraplegics)] to prolonged exercise. In addition, we describe the responses of three tetraplegic athletes [T2: n?=?3 (lesion levels C6/C7: tetraplegics)]. Twenty athletes completed 90?min of exercise at 75% [Vdot]O_2peak on a motorized treadmill adapted for wheelchairs. The mean (±s) heart rates of the T3 and T4 racing classes were 165±2 and 172±6 beats?·?min^?1, respectively. For the T4 racing class, heart rate gradually increased during the test (P?<0.05), whereas for the T3 racing class, heart rate reached a plateau after an initial increase. The mean heart rate of the tetraplegics was 114±3 beats?·?min^?1. The T3 and T4 classes exhibited similar respiratory exchange ratios, plasma lactate and glucose concentrations throughout the test. For both the T3 and T4 racing class, free fatty acid, glycerol, ammonia, urea and potassium concentrations had increased from resting values by the end of the test (P?<0.05). In conclusion, the results of this study suggest that endurance-trained wheelchair athletes are able to maintain velocities equivalent to the same relative exercise intensity (75% [Vdot]O_2peak) for prolonged periods irrespective of lesion level.
