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.     

Digital downsides: exploring university students’ negative engagements with digital technology

Digital technologies are now an integral feature of university study. As such, academic research has tended to concentrate on the potential of digital technologies to support, extend and even ‘enhance’ student learning. This paper, in contrast, explores the rather more messy realities of students’ engagements with digital technology. In particular, it focuses on the aspects of digital technology use that students see as notably unhelpful. Drawing on a survey of 1658 undergraduate students from two Australian universities, the paper highlights four distinct types of digital ‘downside’. These range from low-level annoyances and interruptions, to ways in which digital technologies are seen to diminish students’ scholarship and study. Against this background, the paper considers how discussions of digital technology might better balance enthusiasms for what we know might be achieved through technology-enabled learning, with the often unsatisfactory realities of students’ encounters with digital technology.     

How do teachers help children to learn? An analysis of teachers' interventions in computer-based activities

In British schools, educational software is normally used by children working under the supervision of a teacher, who will have set them specific tasks and organize them to work at the computer in pairs or groups. However, those theories of learning which have most influenced research into the design and use of educational software have been essentially concerned with individualized learning, and are insensitive to the nature of teaching and learning as a communicative, culturally-based process. The present paper discusses an alternative theoretical perspective, one derived from the work of Vygotsky. This is used in an analysis of interventions made by teachers in the computer-based activities of their pupils, using observational data gained from video-recordings of primary school classrooms. The usefulness of the theoretical perspective is evaluated, and implications for the development of computer-based activities are discussed.     

An Aid to Intuitively Understanding Bias and Consistency

Students often find the concepts of bias and consistency hard to understand intuitively. This article presnts means of demonstrating these concepts using a computer so that students, once they have seen them in action, can more readily grasp their meanings and imlications.     

A comparison of freshmen and seniors on general and specific essay tests of critical thinking

There is much interest in the impact of college on critical thinking ability. Freshmen and seniors at a mideastern university were given either a general instruction or multiple specific instructions for critically evaluating one of two articles. All critiques were in essay form. Seniors provided more appropriate criticisms to both kinds of instructions for both articles. However, the absolute level of performance of seniors reflected major deficiencies in applying critical evaluation skills. It was concluded that while college seems to be having an impact, greater emphasis is needed on more directly teaching critical thinking skills in the classroom.     

Mathematical thinking in second-grade children with different forms of LD

Based on their performance on a standardized achievement test, second-grade children (N = 49) were classified as having mathematics difficulties with normal reading achievement (MD only), both mathematics and reading difficulties (MD/RD), reading difficulties with normal mathematics achievement (RD only) and normal mathematics and reading achievement (NA). Each child was given a series of tasks so that we might assess their thinking across four areas of mathematics: number facts, story problems, place value, and written calculation. Children with MD/RD performed significantly worse than NA children in most areas of mathematical thinking, whereas children with MD only performed worse than NA children only on complex story problems. The MD-only group outperformed the MD/RD group on story problems and written calculation. No significant differences were found between the RD-only and NA groups on any of the tasks. The results suggested that among children with mathematics difficulties, the MD/RD subgroup is distinct from the MD-only subgroup, with the former being characterized by pervasive deficiencies in mathematical thinking and the latter by more specific deficits in problem solving.     

Self-regulatory climate: A positive attribute of public schools

This study contributes to the development of a positive framework for effective public schools in 2 ways. First, it advances the construct self-regulatory climate as consisting of 3 generative school norms—collective faculty trust in students, collective student trust in teachers, and student-perceived academic emphasis. The authors argue these norms signal a school climate supportive of student psychological needs. Second, they test the predictive validity of self-regulatory climate by empirically examining its relationship with school performance. Results of structural equation modeling support the theory that collective faculty trust in students, collective student trust in teachers, and student-perceived academic emphasis combine to form a self-regulatory climate that has positive consequences for urban school performance.
