Over the last few decades, technical as well as cognitive skills and their relation to positionspecific skill requirements have been extensively investigated as ndicators for players’ performance in team sports. To explore the impact of positioning in football on inattentional blindness we employed dynamic tasks that presented an unexpected object and analyzed its noticing rates in three different
experiments. In Experiment 1, amateur and expert football players performed a well-established inattentional blindness task of counting the number of times a basketball was passed between two groups while an unexpected, non-sport specific object was introduced to the situation. Noticing rates were higher for strikers compared to players of other playing positions. The findings support a position-specific advantage regarding inattentional blindness for more offensive players compared to more defensive players. Using the same inattentional blindness task, this finding was investigated in Experiment 2 in more detail, i.e., by differentiating between more playing positions. Results revealed that offensive players (in particular strikers) observed unexpected objects more frequently than defensive players. Experiment 3 used a newly developed football-specific task requiring participants to find solutions in different game situations with an unexpected free-standing player appearing in one of these situations. Defensive players again showed more inattentional blindness than offensive players (in particular offensive mid-fielders), i.e., offensive players perceived the unmarked player
more often. This indicates that players not only differ in the conscious perception of unexpected objects that are irrelevant to the sport as a function of their playing position, but also show differences when the perception of the unexpected relevant object is useful for finding tactical solutions in a given game situation. Our findings provide further insight into the importance of the definition of position-specific skill requirements in team sports.
As a result of the abrupt closures of daycare centers in Germany due to the COVID-19 pandemic, parents’ ability to provide learning opportunities at home became all the more important. Building on the family stress model, the study investigates how parental stress affected changes in parents’ provision of home learning activities (HLA) during the lockdown, compared to before the lockdown. In addition, the study considers parental self-efficacy and perceived social support as protective factors that may play important roles in disrupting the negative effects of stress. Data stems from a nation-wide survey of 7,837 German parents of children ages 1–6 years, which was conducted in Spring 2020 during the first wave of COVID-19 infections and at a time of strict restrictions in Germany. Results revealed that parental stress was negatively related to changes in the provision of HLA. Parental self-efficacy and an intact social support system were protective of parental stress during the lockdown. Additionally, parental self-efficacy and – to a larger extend – perceived social support interacted with parental stress in the relation to changes in the provision of HLA. Specifically, self-efficacy and perceived social support acted as protective factors that buffered the negative influence of stress on parents’ ability to provide educational activities for their children at home. These results have important implications for supporting families with young children during challenging times, such as the COVID-19 pandemic and the temporary closure of daycare centers.
Conceptual descriptions and measures of information and entropy were established in the twentieth century with the emergence of a science of communication and information. Today these concepts have come to pervade modern science and society, and are increasingly being recommended as topics for science and mathematics education. We introduce a set of playful activities aimed at fostering intuitions about entropy and describe a primary school intervention that was conducted according to this plan. Fourth grade schoolchildren (8–10 years) played a version of Entropy Mastermind with jars and colored marbles, in which a hidden code to be deciphered was generated at random from an urn with a known, visually presented probability distribution of marble colors. Children prepared urns according to specified recipes, drew marbles from the urns, generated codes and guessed codes. Despite not being formally instructed in probability or entropy, children were able to estimate and compare the difficulty of different probability distributions used for generating possible codes.
Sustainability competence is an important goal of Education for Sustainable Development (ESD) in school. It is therefore anchored in the education plans of almost all school tracks in Germany. However, empirical findings regarding ESD in schools are scarce. The present study thus examined how sustainability competencies of secondary-school students develop within the course of a school year. Based on a proposed framework model of sustainability competencies, we assessed (a) students’ sustainability-related knowledge, (b) their affective-motivational beliefs and attitudes towards sustainability, as well as (c) their self-reported sustainability-related behavioral intentions. Our sample comprised n = 1318 students in 79 classrooms at different secondary school tracks (Grades 5–8) in Baden-Wuerttemberg (Germany). Measurements were taken at the beginning and at the end of the school year after the introduction of ESD as a guiding perspective for the new education plan. We observed an increase in students’ sustainability-related knowledge but a decline in their affective-motivational beliefs and attitudes towards sustainability over the course of one school year. Multilevel analyses showed that, at the individual level, prior learning requirements as well as ESD-related characteristics (students’ activities and general knowledge of sustainability) proved to be the strongest predictors of their development. In addition, grade- and track-specific differences were observed. At the classroom level, teachers’ attitudes towards ESD as well as their professional knowledge were found to be significant predictors of students’ development. The higher the commonly shared value of ESD at school and the higher teachers’ self-efficacy towards ESD, the higher was the students’ development of sustainability-related knowledge and self-reported sustainability-related behavioral intentions, respectively. The significance of the findings for ESD in schools is discussed.
If information on single items in the Short Form–12 health survey (SF-12) is missing, the analysis of only complete cases causes a loss of statistical power and, in case of nonrandom missing data (MD), systematic bias. This study aimed at evaluating the concordance of real patient data and data estimated by different MD imputation procedures in the items of the SF-12 assessment. For this ends, MD were examined in a sample of 1,137 orthopedic patients. Additionally, MD were simulated (a) in the subsample of orthopedic patients exhibiting no MD (n = 810; 71%) as well as (b) in a sample of 6,970 respondents representing the German general population (95.8% participants with complete data) using logistic regression modelling. Simulated MD were replaced by mean values as well as regression-, expectation-maximization- (EM-), and multiple imputation estimates. Higher age and lower education were associated with enhanced probabilities of MD. In terms of accuracy in both data sets, the EM-procedure (ICC2,1 = .33-.72) outperformed alternative estimation approaches substantially (e.g., regression imputation: ICC2,1 = .18-.48). The EM-algorithm can be recommended to estimate MD in the items of the SF-12, because it reproduces the actual patient data most accurately.
Systems thinking provides many advantages in solving complex scientific, economic and sociocultural problems in the field of education for sustainable development. Various studies have shown that systems thinking can be promoted in students at all levels of school education. Previous studies have mainly focused on how to directly develop and support systems thinking in students. The present study focused on biology teachers by investigating the extent that their content knowledge (CK) and pedagogical content knowledge (PCK) augments systems thinking in students attending biology classes. On the basis of the finding that content knowledge (CK) and pedagogical content knowledge (PCK) are an essential aspect of any type of training, we investigated in a teacher training program the effects of varying amounts of CK and PCK to the ability of biology teachers to foster systems thinking in students. Therefore, a quasi-experimental intervention study was implemented in a pre- and posttest control group design. The results revealed that biology teacher training can sufficiently improve systems thinking in biology students and that PCK plays an at least equally important role as CK in promoting systems thinking.
Abstract
The following paper presents the structure of a language teaching inspection of the topic of capitalization applied within sentences in the secondary education level, which comprises both a quantitative and a qualitative research part. The emphasis of this paper, in respect to its content, does not lie in the discussion of each and every result, but concentrates on the question of how the quantitative and qualitative results can be correlated to each other, and on what types of complementary information can be deducted from it from a language teaching point of view.
Professional knowledge is highlighted as an important prerequisite of both medical doctors and teachers. Based on recent conceptions of professional knowledge in these fields, knowledge can be differentiated within several aspects. However, these knowledge aspects are currently conceptualized differently across different domains and projects. Thus, this paper describes recent frameworks for professional knowledge in medical and educational sciences, which are then integrated into an interdisciplinary two-dimensional model of professional knowledge that can help to align terminology in both domains and compare research results. The models’ two dimensions differentiate between cognitive types of knowledge and content-related knowledge facets and introduces a terminology for all emerging knowledge aspects. The models’ applicability for medical and educational sciences is demonstrated in the context of diagnosis by describing prototypical diagnostic settings for medical doctors as well as for teachers, which illustrate how the framework can be applied and operationalized in these areas. Subsequently, the role of the different knowledge aspects for acting and the possibility of transfer between different content areas are discussed. In conclusion, a possible extension of the model along a “third dimension” that focuses on the effects of growing expertise on professional knowledge over time is proposed and issues for further research are outlined.
