Is there an ideal time window for language acquisition after which nativelike
representation and processing are unattainable? 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.
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.
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. Educational implications are discussed.
Between-school variation in students' achievement, motivation, affect, and learning strategies
(2017)
To plan group-randomized trials where treatment conditions are assigned to schools, researchers need design parameters that provide information about between-school differences in outcomes as well as the amount of variance that can be explained by covariates at the student (L1) and school (L2) levels. 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.
