Structure and development of pre-service physics teachers’ professional knowledge

ABSTRACT

Teachers’ professional knowledge is considered one of the most important predictors of instructional quality. According to Shulman, such professional knowledge includes content, pedagogical content and pedagogical knowledge. Although recent research shed some light on the structure of the dimensions of professional knowledge, little is known how teacher education impacts pre-service physics teachers’ professional knowledge. In an effort to address this issue, we examined the content, pedagogical content and pedagogical knowledge of N?=?200 pre-service physics teachers enrolled in different years of teacher education at 12 major teacher education universities in Germany. We used structural equation modelling (1) to examine the relations amongst pre-service physics teachers’ content, pedagogical content and pedagogical knowledge, (2) to explore how the three kinds of knowledge and their relations differ across different stages of teacher education and (3) to identify factors affecting the level of each component of professional knowledge. Our findings suggest that content, pedagogical content and pedagogical knowledge represent distinct types of knowledge. Furthermore, our findings show that in the first years of professional education, pedagogical content knowledge is more closely related with general pedagogical knowledge while in later years, it is more closely related with content knowledge, suggesting that it develops from a general knowledge about teaching and learning into knowledge about the teaching and learning of specific content. Finally, beyond school achievement and years of enrolment as predictors, we find in particular the amount of classroom observations to have a positive impact on the professional knowledge of pre-service physics teachers.     

HUMANIZING EDUCATION AND THE EDUCATIONALIZATION OF HEALTH

Abstract Theorists often take a condescending stance when speaking about the educationalization of social problems. Given their confidence with postmodern and poststructuralist perspectives, the educationalization of social problems is easily perceived as a set of questionable interventions by governments into educational practices. In this essay, Bert Lambeir and Stefan Ramaekers question the extent to which one can conceive of social problems without an understanding of education or, put more sharply, the extent to which social problems are conceivable without some form of educationalization. After describing four meanings of the concept of educationalization, Lambeir and Ramaekers discuss three popular criticisms of it. With these criticisms as context, the authors use the example of concerns about and initiatives in health education to investigate whether education can be completely freed from the educationalization of social issues. They conclude that it cannot.     

Autism Spectrum Disorders: Neurobiology and current assessment practices

This study reviews recent research related to the neurobiology of Autism Spectrum Disorders (ASDs) an provides an empirical analysis of current assessment practices. Data were collected through a survey of 117 school psychologists. The Childhood Autism Rating Scale (CARS), Gilliam Autism Rating Scale (GARS), and Gilliam Asperger's Disorder Scale (GADS) were the most frequently used measures. Among the less popular, but more intensive instruments, the Autism Diagnostic Observation Schedule (ADOS) appears to be gaining popularity within school‐based evaluations. Generally, respondents approached the assessment of ASDs from a traditional psychoeducational perspective and reported the use of a very narrow range of ASD‐specific instruments. Concerns are raised regarding the inconsistent inclusion of developmental questionnaires, parent/guardian interviews, and medical professionals in the ASD evaluation process. Implications for practice and the training of school psychologists are discussed. © 2008 Wiley Periodicals, Inc.     

语言正在全球5个热点地区快速消亡

语言学家警告说,每两个星期就至少有一种语言从地球上消亡。语言消亡这种现象是语言自身进化中的一个阶段还是退化中的一个阶段?在一些语言消亡的同时,一些新的语言也在出现。我们要尽可能地挽救语言消亡给人类文化带来的损失,但就语言本身来说,我们也不需要过分恐慌……     

Der Mathematikunterricht der PISA-Schülerinnen und -Schüler

Der Beitrag besch?ftigt sich mit dem Mathematikunterricht der PISA-Schülerinnen und -Schüler in Deutschland und berichtet über Ergebnisse aus einer Zusatzstudie zu PISA 2003. Aufbauend auf der mathematik-didaktischen Rahmenkonzeption von PISA, die Unterricht als Gelegenheitsstruktur für verst?ndnisvolle Lernprozesse versteht, wurden Schülerinnen und Schüler und ihre Mathematiklehrkr?fte zu Merkmalen der Unterrichtsqualit?t befragt. Es zeigen sich schulformspezifische Unterrichtskulturen: Ein kognitiv aktivierender Umgang mit mathematischen Inhalten ist eher in Gymnasien zu beobachten, w?hrend vor allem in Hauptschulen die Unterrichtsform mit geringem kognitiven Gehalt und ausgepr?gter Unterstützung überwiegt. Dennoch wird die Angebotsstruktur des Mathematikunterrichts von Jugendlichen an Hauptschulen positiv beurteilt, w?hrend Gymnasiasten ihren Unterricht eher kritisch bewerten. Diese Differenzen sind vor allem durch Unterschiede in der individuellen Lernunterstützung durch die Lehrkr?fte zu erkl?ren, welche von Schülerinnen und Schülern an Hauptschulen als besonders ausgepr?gt, an Gymnasien eher als gering beschrieben wird.

Flexible use of lexical and sublexical information in word recognition

Within the dual‐route framework it is hypothesised that readers exhibit flexibility in their use of lexical and non‐lexical information in word naming. In the present study, participants named high‐ and low‐frequency regular one‐syllable English words embedded within lists of regular or irregular one‐ or two‐syllable English words. A large number of irregular words should bias the reader toward the lexical route, whereas a list consisting exclusively of regular words should allow more efficient use of sublexical information present in the word. Word frequency effects were obtained when the list was dominated by either regular or irregular two‐syllable filler words. Furthermore, there was an interaction between frequency and regularity for the one‐syllable words, indicating that the frequency effect was significantly larger when the fillers were one‐syllable irregular words relative to one‐syllable regular words. These results extend those reported for a shallow orthography, and indicate strategic control over the use of phonological and lexical information in English word recognition.
