Although this question has been heavily debated, no consensus has been reached. Here, we present evidence for a sensitive period in language development and show that it is specific to grammar. We conducted a masked priming task with a group of Turkish-German bilinguals and examined age of acquisition (AoA) effects on the processing of complex words. We compared a subtle but meaningful linguistic contrast, that between grammatical inflection and lexical-based derivation. The results showed a highly selective AoA effect on inflectional (but not derivational) priming. In addition, the effect displayed a discontinuity indicative of a sensitive period: Priming from inflected forms was nativelike when acquisition started before the age of 5 but declined with increasing AoA. We conclude that the acquisition of morphological rules expressing morphosyntactic properties is constrained by maturational factors.}, language = {en} } @misc{KrauskopfFoulgerWilliams2017, author = {Krauskopf, Karsten and Foulger, Teresa S. and Williams, Mia Kim}, title = {Prompting teachers' reflection of their professional knowledge}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {466}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-412628}, pages = {23}, year = {2017}, abstract = {Many educational technology proponents support the Technological Pedagogical Content Knowledge (TPACK) model as a way to conceptualize teaching with technology, but recent TPACK research shows a need for empirical studies regarding the development of this knowledge. This proof-of-concept study applies mixed-methods to investigate the meta-cognitive awareness produced by teachers who participate in the Graphic Assessment of TPACK Instrument (GATI). This process involves creating graphical representations (circles of differing sizes and the degree of their overlap) that represent what teachers understand to be their current and aspired TPACK. This study documented teachers' explanations during a think-aloud procedure as they created their GATI figures. The in-depth data from two German teachers who participated in the process captured the details of their experience and demonstrated the potential of the GATI to support teachers in reflecting about their professional knowledge and in determining their own professional development activities. These findings will be informative to future pilot studies involving the larger design of the GATI process, to better understand the role of teachers' meta-conceptual awareness, and to better ascertain how the GATI might be used to support professional development on a larger scale.}, language = {en} } @misc{Grell2017, author = {Grell, Petra}, title = {Learning and teaching in adult education}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-403628}, pages = {3}, year = {2017}, language = {en} } @misc{WestphalVockStubbe2017, author = {Westphal, Andrea and Vock, Miriam and Stubbe, Tobias}, title = {Grade skipping from the perspective of teachers in Germany}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {411}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-405235}, pages = {14}, year = {2017}, abstract = {The present study explored teachers' perspectives on one specific type of acceleration, namely, grade skipping. In addition, we investigated the extent to which teachers' beliefs about students' academic, motivational, and social development after grade skipping may explain teachers' acceptance of this accelerative strategy. Moreover, we examined whether teachers' acceptance is linked to their decisions about using this intervention. Using data from the PARS project, which included 316 teachers from 18 secondary schools in the German federal state of North Rhine-Westphalia, we assessed teachers' acceptance, beliefs, and perceived knowledge about grade skipping using 4-point rating scales. Teachers also reported whether they had advised a student to skip a grade. Multilevel regression analyses indicated that teachers' beliefs about students' social, motivational, and academic development largely explained their acceptance. Teachers who showed a higher level of acceptance and perceived knowledge were more likely to have recommended grade skipping before.

Most previous research has offered these parameters for U.S. samples and for achievement as the outcome. This paper and the online supplementary materials provide design parameters for 81 countries in three broad outcome categories (achievement, affect and motivation, and learning strategies) for domain-general and domain-specific (mathematics, reading, and science) measures. Sociodemographic characteristics were used as covariates. Data from representative samples of 15-year-old students stemmed from five cycles of the Programme for International Student Assessment (PISA; total number of students/schools: 1,905,147/70,098). Between-school differences as well as the amount of variance explained at L1 and L2 varied widely across countries and educational outcomes, demonstrating the limited generalizability of design parameters across these dimensions. The use of the design parameters to plan group-randomized trials is illustrated.}, language = {en} }
