CREATIVITY: IDIOGRAPHIC VERSUS NOMOTHETIC APPROACH

Two main approaches exist in the study of personality: idiographic vs. nomothetic. A combination of both is called psychological biography, i.e., an integration of nomothetic objectives and idiographic completeness. This approach was applied by Gardner in analyzing seven creative‐productive personalities. In Gardner's view the development of creating minds is not only dependent on a supportive environment, but also cultural and/or societal acceptance. The mastery of a particular creative direction starts in the early years and mastery needs exercise. Moreover, the examples given by Gardner lead to the conclusion that creativity does not exist as a general trait, but is alway domain specific.     

Student-centred anti-smoking education: Comparing a classroom-based and an out-of-school setting

The present study monitored a student-centred educational anti-smoking intervention with fifth graders by focusing on their cognitive achievement and intrinsic motivation. In order to assess the potential influence of the setting on self-directed learning, the intervention was conducted in two different learning environments: a classroom-based group in class at school; and an out-of-school group in an outreach setting at a youth camp. A control group didn’t experience any specific intervention. Outcomes were assessed with an achievement test and the Intrinsic Motivation Inventory. Although in both learning settings similar cognitive levels were achieved, the out-of-school group showed a larger decrease in cognitive achievement and lower intrinsic motivation scores for interest and perceived choice. This empirical study adds new evidence to student-centred learning schemes in different learning environments, especially in an interdisciplinary context.     

Solving Developmental Tasks in Adolescents with a Chronic Physical Illness or Physical/Sensory Disability: A Meta-analysis

Chronic illnesses and disabilities may impair the attainment of age-typical developmental tasks, such as forming relationships with peers and gaining autonomy. Based on a systematic search in electronic databases and cross-referencing, 447 quantitative empirical studies were included which compared the attainment of developmental tasks of adolescents with and without chronic physical illness or physical/sensory disability. Adolescents with chronic illness or disability had more problems than healthy/nondisabled peers with regard to autonomy, body acceptance, developing friendships and romantic relationships, gaining access to a peer-group, career preparation, preparing for family life and developing socially responsible behaviour. However, between-group differences were small. No between-group differences were found regarding gender role acquisition and identity development. Success in solving developmental tasks varied, in part, by disease group, visibility of the disease/disability, age, gender and representativeness of the sample. Interventions aimed at promoting the attainment of developmental tasks are recommended.     

A Field-Based Testing Protocol for Assessing Gross Motor Skills in Preschool Children: The Children's Activity and Movement in Preschool Study Motor Skills Protocol

The purpose of this study was to develop a valid and reliable tool for use in assessing motor skills in preschool children in field-based settings. The development of the Children's Activity and Movement in Preschool Study Motor Skills Protocol included evidence of its reliability and validity for use in field-based environments as part of large epidemiological studies. Following pilot work, 297 children (3–5 years old) from 22 preschools were tested using the final version of the Children's Activity and Movement in Preschool Study Motor Skills Protocol and the Test of Gross Motor Development (2nd Edition). Reliability of the Children's Activity and Movement in Preschool Study Motor Skills Protocol and interobserver reliability were determined using intraclass correlation procedures (intraclass correlation coefficients; ANOVA). Concurrent validity was assessed using Pearson correlation coefficients to compare the Children's Activity and Movement in Preschool Study Motor Skills Protocol to the original Test of Gross Motor Development (2nd Edition). Results indicated that test reliability, interobserver reliability, and validity coefficients were all high, generally above R/r = .90. Significant age differences were found. Outcomes indicate that the Children's Activity and Movement in Preschool Study Motor Skills Protocol is an appropriate tool for assessing motor development of 3-, 4-, and 5-year-old children in field-based settings that are consistent with large-scale trials.     

An Examination of Sport Participation Tracking and Adult Physical Activity for Participants of the Michigan State University Motor Performance Study

ABSTRACT

Research tracking sport participation from youth to adulthood is relatively rare, as is research that tracks youth sport participation with regard to adult physical activity (PA) levels, especially in the United States. Aims of this study were: 1) To investigate the degree to which sport participation tracked across youth, adolescence, and early adulthood in a sample of participants from the Michigan State University Motor Performance Study (MPS), and 2) Determine if differences existed in their levels of adult PA relative to prior sport participation. In total, 256 (60.8%) former participants from the MPS completed follow-up surveys regarding routine sport participation and PA across the previous year. Sport participation tracked consistently from youth to college. Further, regardless of the level of youth sport participation, adult leisure time PA was relatively consistent among groups. Although the study did not directly test the influence of the MPS on subsequent adult outcomes, our findings suggest that participants’ past sport participation was not a good predictor of adult PA for those who were involved in a program that emphasized fundamental motor skills in youth. Further investigation of such programs can help to better inform their influence on adult PA.     

Learning at workstations in two different environments: A museum and a classroom

Our study compared the learning and motivational outcome of one educational approach in two different learning environments, a natural science museum and a classroom, drawing on studies about the effects of field trips on students’ learning and motivation. The educational intervention consisted of an introduction phase in the classroom and subsequent learning at workstations, either in the museum or the classroom. 190 secondary school students participated in the quasi-experimental design. We assessed knowledge and understanding by using a pre-, post- and retention-test design, and applied subscales of the ‘Intrinsic Motivation Inventory’ to consider motivational aspects. Students of the museum-group learnt more compared to the classroom-group, whereas motivation differed only in one subscale of the motivation test, with higher scores for the museum-group. Results are discussed in terms of the overall added value of field trips for school curricula.     

Investigating the impact of observation errors on the statistical performance of network-based diffusion analysis

Experiments in captivity have provided evidence for social learning, but it remains challenging to demonstrate social learning in the wild. Recently, we developed network-based diffusion analysis (NBDA; 2009) as a new approach to inferring social learning from observational data. NBDA fits alternative models of asocial and social learning to the diffusion of a behavior through time, where the potential for social learning is related to a social network. Here, we investigate the performance of NBDA in relation to variation in group size, network heterogeneity, observer sampling errors, and duration of trait diffusion. We find that observation errors, when severe enough, can lead to increased Type I error rates in detecting social learning. However, elevated Type I error rates can be prevented by coding the observed times of trait acquisition into larger time units. Collectively, our results provide further guidance to applying NBDA and demonstrate that the method is more robust to sampling error than initially expected.

Efficacy of Two Different Instructional Methods Involving Complex Ecological Content

Teaching and learning approaches in ecology very often follow linear conceptions of ecosystems. Empirical studies with an ecological focus consistent with existing syllabi and focusing on cognitive achievement are scarce. Consequently, we concentrated on a classroom unit that offers learning materials and highlights the existing complexity rather than following linear conceptions. We developed an educational unit consisting of 14 individual lessons (”ecosystem lake”) with the aim of increasing pupils’ cognitive achievement in 8th and 9th grade secondary schools. To evaluate our approach, we chose a quasi-experimental design and five teachers with ten classes participated in our study. A matched-pair tandem-design was provided by five German teachers using first his/her conventional approach in one class (instruction-1; control group) and second, our modern ecological approach in their second class (instruction-2). Pupils subjected to the latter performed better, i.e., achieved higher scores, especially in the delayed post-test. Further, we found a teacher effect and an interaction between treatment (i.e., whether treatment or control class) and the teacher regarding the class test. Teachers had a significant influence on the learning outcome irrespective of the educational unit, i.e., some teachers generally produced higher achievement than others. Further, the interaction showed that some teachers coped better with their traditional teaching. Nevertheless, in retention (delayed post-test) all classes of the modern approach scored higher than the traditionally taught ones. Boys and girls benefited equally from our program and pupils from the modern approach rated the educational unit better. Figure 1 Overview over the educational unit “ecosystem lake”     

Effects of a 1-day environmental education intervention on environmental attitudes and connectedness with nature

Besides cognitive learning effects, short-term environmental education (EE) is often regarded as ineffective in intervening with participants' environmental attitudes and behaviour. However, in Germany, school classes often participate in such 1-day EE programmes because they better match the school curriculum in contrast to longer (residential) programmes. We therefore monitored a 1-day outreach EE programme on global climate change to reveal whether environmental attitudes and/or connectedness with nature of tenth graders are affected. Students from German high schools (college preparatory secondary school level, ‘Gymnasium’) (N?=?114) from age 14 to 19 participated in the programme (treatment group). It consisted of two student-centred learning units on the topic of climate change. Additionally, we chose a control group of students who did not participate in the programme. To measure students' environmental attitudes and connectedness with nature, we administered the Two Major Environmental Values (2-MEV) and the Inclusion of Nature in Self scale in a pre-, post- and retention test design. The pre-test was administered 1 week before, the post-test directly after and the retention test 4 to 6 weeks after programme participation. Analyses revealed a positive long-term effect only for utilitarian values (one of the two major environmental factors of 2-MEV) which decreased significantly. Therefore, depending on the programme's content, short-term EE programmes indeed may have an influence on participants' environmental attitudes.
