Can competencies assessed by PISA be considered the fundamental school knowledge 15-year-olds should possess?

The OECD Programme for International Student Assessment (PISA), launched by governments of the Organisation for Economic Co-operation and Development (OECD) in 1997, aims at assessing some of the key competencies that contribute to the success of 15-year-old individuals, on a regular basis and within an internationally accepted framework. PISA seeks to provide a basis for policy dialogue and for collaboration in defining and implementing educational goals, in innovative ways that reflect judgements about the skills that are relevant to adult life. PISA defines competence as the ability to successfully meet complex demands in varied contexts through the mobilisation of psychosocial resources, including knowledge and skills, motivation, attitudes, emotions, and other social and behavioural components. Measuring and comparing competencies across languages and cultures is a difficult challenge and is being pursued by PISA progressively. PISA focused its first three assessments on literacy skills, defined as the capacity of young adults to access, manage, integrate and evaluate information, to think imaginatively, to hypothesise and discover, and to communicate their thoughts and ideas effectively. The reasoning behind shifting the emphasis from assessing whether students can reproduce what they have learned towards whether they can extrapolate from what they have learned and apply their competencies in novel situations, derives from the nature of knowledge and skills required in modern life. For example, the tasks that can be solved through simple memorisation or with pre-set algorithms are those that are also easiest to digitise, automatise and offshore, and will thus be less relevant in a modern knowledge society. Since there is no overarching cross-national and cross-cultural agreement on what fundamental competencies 15-year-olds should possess, an international assessment such as PISA can only capture a selection of competencies. Moreover, since various methodological constraints limit the nature of competencies that are currently amenable to large scale assessment, PISA cannot capture the entirety of competencies that will make young people successful. However, the findings presented in this article suggest that the competencies that PISA does assess are highly predictive for the future success of students. In addition, PISA provides policy makers and practitioners with useful tools to improve quality, equity and efficiency in education, by revealing some common characteristics of students, schools and education systems that do well. In a modern world, comparative assessments are an essential tool for educational improvement and research shows that the existence of standardised assessments and examinations is one of the most powerful predictors for the success of an education system. That is not hard to understand, because without such assessments, all students, schools and education systems look the same, it is impossible for teachers and school administrators to detect institutional and systemic strengths and weaknesses, and to support and intervene where expectations are not met. Without reliable and comparable information on learning outcomes, teachers and governments alike rely on input-based incentives and policies that are all too often mirrored in large quality variation between schools as well as a strong dependency between learning success and the socio-economic context of students and schools. Last but not least, it is important to keep in mind that the absence of the reading, mathematical and scientific competencies measured by PISA does not automatically imply the presence of all those important competencies that have not been measured.     

Die Effektivität schriftlicher und kombiniert auditiv-schriftlicher Wortschatzfördermaßnahmen bei Kindern mit nichtdeutscher Herkunftssprache

Disparities in language competencies of children with and without immigrant background are well-documented through large scale assessments. This study investigates the potential of implicit language promotion, presented in written and combined auditory-written formats. Three experimental groups of 4^th graders in elementary schools have been compared. Intervention group (IV) 1 (n?=?33) read the intervention texts two times in German, IV 2 (n?=?52) read texts in their heritage language Turkish and afterwards in German, and IV 3 (n?=?35) listened to texts in Turkish first and read them in German afterwards. All children learned new vocabulary, but analyses of variance showed that students from IV 2 achieved greater vocabulary gains than IV 3. Results also do not support advantages for the combined auditory-written form including the heritage language. Students’ text comprehension and reading competencies influence their incidental vocabulary acquisition. The results are discussed in the light of practical and research implications.     

Student Preschool Teachers’ Experiences of Science and Its Role in Preschool

This article reports on student preschool teachers’ views of science and its role in preschool. Three cohorts of students have been given a written questionnaire with open-ended questions before and after a one-semester course including science (specifically Chemistry and Physics) in a 3.5-year preschool teacher programme in Sweden. The science content in the course is integrated with other subjects and lecturers with different subject backgrounds work together in forming an integrated and meaningful context. A phenomenographic qualitative analysis of responses to the questionnaires before and after the course is presented. The analysis indicated that many students equate science with biology (nature studies), and several did not adjust this view even though chemistry and physics were explicitly taught. Surprisingly few students were negative towards science, none after the course. However, several remain hesitantly positive. Most students described ‘what’ and ‘how’ perspectives of science, but few developed a synthesised view of science activities. However, there was a shift towards a more integrated perspective after the course. Also the quality and eloquence of the students’ responses were noticeably improved in responses given after the course. Prior expectations and implications of the results for preschool teacher education are discussed.     

Headsprout® Early Reading for children with severe intellectual disabilities: a single blind randomised controlled trial

Research evaluating phonics reading programs for children with severe intellectual disabilities (ID) is limited. The current study investigated whether using an online reading program (Headsprout^® Early Reading; HER) as supplementary reading instruction for children with a severe ID leads to improvements in reading skills as compared to children not receiving this additional instruction. Fifty-five children from a special school were randomly allocated into the HER group or a waiting list control group. For six months, children in the intervention group received HER as supplementary instruction, whereas children in the control group received only ‘reading as usual’ teaching. Pre- and post-intervention tests on standardised reading measures were conducted. Analysis of data from outcome measures indicated that the HER group made improvements at post-intervention in comparison with the control group, with medium effect sizes on two domains from the main outcome measure. These results support the case for a larger research trial of HER for children with severe ID.     

Acute exercise-induced irisin release in healthy adults: Associations with training status and exercise mode

There is a growing interest in exploring irisin response to acute exercise; however, the associations of acute exercise-induced irisin release with training status and exercise mode are not fully understood. This study was primarily designed to evaluate these associations. Sixteen healthy adults (8 trained versus 8 untrained) underwent a bout of cycling at 80% of maximal oxygen uptake (VO_2max) for 50?min, with blood drawn pre-, 10-, and 180-min post-exercise. Another 17 healthy adults performed 2 bouts of graded exercise (cycling and running) until exhaustion on separate days using a randomized cross-over design, with blood taken pre-, 0-, 10-, and 60-min post-exercise. Circulating irisin, creatine kinase (CK), aspartate aminotransferase (AST), and myoglobin (Mb) were measured, and their respective areas under the curves (AUCs) were calculated. Irisin increased 10-min after 50?min of cycling at 80% of VO_2max, while its changes from baseline to post-exercise and the amount of exercise-induced irisin release (presented as AUC) were comparable between trained and untrained adults (all P?>?.05). Irisin remained elevated 10-min post-exhausting running but decreased towards baseline 10-min post-exhausting cycling. Exhausting running induced an increase in irisin release for the whole course of exercise and recovery periods, but cycling did not. Acute exercise-induced irisin changes seemed not related to changes of CK, aspartate AST, and Mb in general. In conclusion, acute exercise-induced irisin release is not associated with training status but might be affected by training mode. Future studies are required to investigate which exercise mode might be most efficient in altering irisin.     

Prognostic validity of talent orientation in soccer

Several talent-screening programs conducted within elementary schools have implemented motor diagnostics to introduce children to groups of sports including both game and specific sports, the latter of which includes gymnastics, skiing, and tennis. However, as in most other sports, the predictive value for soccer regarding such early testing is unclear. This prospective cohort study evaluated the mid-term prognostic validity of general motor tests as well as a soccer-specific score calculated from a test battery. The sample consisted of N?=?2965 U9 age group of children from the Fulda Movement Check (FMC). The FMC is a basic check comprised of two anthropometric parameters and eight general items of the German Motor Test 6–18 by Boes and Schlenker with the addition of a ball throw. The test data were collected from the second grade classes of 2011–2014. The soccer competition performance of those children who chose soccer (n?=?316) up to the end of the season 2016/17 (September 30, 2017) was recorded. This group of U12–U15 players was then assigned individually to four different competition levels. The prognostic validity of the motor tests was determined using analysis of variance, odds ratios, and a discriminant analysis. All diagnostic methods exhibited medium to high prognostic validity over the 2? to 6?year time span from the talent screening and talent orientation period to the later soccer competitions in the early adolescent U12–U15 age groups. The prognostic relevance of the nine general motor tests was confirmed.     

Szenario-basierter Systemtest von Software-Produktfamilien

In der Produktfamilienentwicklung werden durch zwei Entwicklungsprozesse, Domain und Application Engineering, zun"achst wiederverwendbare Entwicklungsartefakte produziert, um diese anschlie?end zur Konstruktion von kundenspezifischen Applikationen einzusetzen. Die Wiederverwendbarkeit wird durch die explizite Definition der Variabilit"at der geplanten Applikationen einer Produktfamilie erzielt. Diese proaktive Wiederverwendung ist bisher in den konstruktiven Entwicklungsphasen realisiert, jedoch noch nicht im Test. Mit ScenTED (Scen_ario based TE_st Case D_erivation) wird in diesem Beitrag eine wiederverwendungsorientierte Technik zur Testfallerstellung f"ur den Systemtest, dem Test eines ausf"uhrbaren Systems gegen spezifizierte Use-Cases, von Produktfamilien vorgestellt. ScenTED basiert auf zwei Kernideen: der Erhaltung der Variabilit"at in Testf"allen und der Szenario-basierten Verfeinerung der Testf"alle. Durch die Erhaltung der Variabilit"at wird die Wiederverwendbarkeit von Testf"allen gesichert; die Szenario-basierte Verfeinerung erm"oglicht Nachvollziehbarkeit durch die durchg"angige Nutzung von Szenarien. In diesem Beitrag wird die ScenTED-Technik an einem Beispiel erl"autert und Erfahrungen aus dem industriellen Einsatz diskutiert.
