Taming a beast of burden – On some issues with the conceptualisation and operationalisation of cognitive load

Research on cognitive load theory (CLT) has not yet provided facet-specific measures of cognitive load. The lack of valid methods to measure intrinsic, extraneous and germane cognitive load makes it difficult to empirically test theoretical explanations of effects caused by manipulations of instructional designs. This situation also imposes challenges to testing CLT as a theory. This paper critically reflects the conceptualisation of CLT's core concept and the implications for its operationalisation. In order to address some of the challenges we propose a complexity framework that allows the derivation of a priori estimates of mental load that go beyond CLT's notion of element interactivity. In a study we test hypotheses with regard to effects of the variation of sources for intrinsic cognitive load (increase of complexity within tasks) and the variation of sources for extraneous cognitive load (reduction of extraneous cognitive load between tasks) in three ability groups. Complexity-based estimates prove superior to element interactivity-based estimates of mental load in the prediction of performance outcomes. Results also indicate that individual differences in information-processing capacity determine to what extent complexity is reflected as cognitive load. In this respect the proposed framework extends the focus of CLT beyond the discussion of the role of prior knowledge and acquired levels of expertise.     

Demanding and resisting vocational education: a comparative study of schools in rural and urban China

The Chinese government is pouring resources into building vocational education at all levels of the Chinese educational system. Based on ethnographic fieldwork conducted in three vocational secondary schools in 2007–2012, this article compares rural and urban schools to highlight the persistent urban–rural divide in implementing vocational education, and to understand popular resistance to vocational education and its effects on students and families. Through observations of classroom practice and interviews with students, parents, teachers, and administrators, the authors investigate the paradox of why vocational education is growing rapidly in China, even though parents and students have deeply-held objections to this form of schooling.     

Psychological Adjustment in Adolescents with Vision Impairment

The present study compared psychological adjustment of 158 adolescents with vision impairment and 158 sighted adolescents with a matched-pair design using the Strengths and Difficulties Questionnaire. Adolescent self-reports and teacher reports on emotional problems, peer problems, and total difficulties showed higher scores in students with vision impairment than in sighted students. However, the size of between-group differences was small, and adolescents who are blind and their peers with low vision showed similar levels of psychological adjustment. In addition, older students reported more emotional problems than younger students. Furthermore, differences between self-reported emotional problems of students with and without vision impairment were stronger in older participants. In both groups, girls showed more emotional problems and less conduct problems than boys. We conclude that most students with vision impairment are well adjusted but a minority may benefit from psychological interventions.     

Gaze Behavior of Gymnastics Judges: Where Do Experienced Judges and Gymnasts Look While Judging?

Gymnastics judges and former gymnasts have been shown to be quite accurate in detecting errors and accurately judging performance. Purpose: The purpose of the current study was to examine if this superior judging performance is reflected in judges’ gaze behavior. Method: Thirty-five judges were asked to judge 21 gymnasts who performed a skill on the vault in a video-based test. Classifying 1 sample on 2 different criteria, judging performance and gaze behavior were compared between judges with a higher license level and judges with a lower license level and between judges who were able to perform the skill (specific motor experience [SME]) and those who were not. Results: The results revealed better judging performance among judges with a higher license level compared with judges with a lower license level and more fixations on the gymnast during the whole skill and the landing phase, specifically on the head and arms of the gymnast. Specific motor experience did not result in any differences in judging performance; however, judges with SME showed similar gaze patterns to those of judges with a high license level, with 1 difference in their increased focus on the gymnasts’ feet. Conclusion: Superior judging performance seems to be reflected in a specific gaze behavior. This gaze behavior appears to partly stem from judges’ own sensorimotor experiences for this skill and reflects the gymnasts’ perspective onto the skill.     

Paul Abraham: A Forgotten Scholar of the Prussian Academy of Sciences and Humanities

Paul Abraham, one of the Berlin Academys most experienced researchers, was deported to Auschwitz in 1943. The fate of this Jewish scholar reveals much about the inner life of the Academy, and its treatment of Jewish staff, during the World War II. This paper describes his life, against a backdrop of war, revolution, and dictatorship, and in the context of one of the Academys most prestigious projects.     

High school peer tutors teach MedlinePlus: a model for Hispanic outreach.

OBJECTIVES: The objective was to introduce the MedlinePlus Website to the predominantly Hispanic residents of the Lower Rio Grande Valley region of Texas by partnering with a health professions magnet high school (known as Med High). METHODS: Community assessment was used in the planning stages and included pre-project focus groups with students and teachers. Outreach methods included peer tutor selection, train-the-trainer sessions, school and community outreach, and pre- and posttests of MedlinePlus training sessions. Evaluation methods included Web statistics; end-of-project interviews; focus groups with students, faculty, and librarians; and end-of-project surveys of students and faculty. RESULTS: Four peer tutors reached more than 2,000 people during the project year. Students and faculty found MedlinePlus to be a useful resource. Faculty and librarians developed new or revised teaching methods incorporating MedlinePlus. The project enhanced the role of school librarians as agents of change at Med High. The project continues on a self-sustaining basis. CONCLUSIONS: Using peer tutors is an effective way to educate high school students about health information resources and, through the students, to reach families and community members.
