Research on mathematics teachers as partners in task design

Mathematical tasks and tools, including tasks in the form of digital tools, are key resources in mathematics teaching and in mathematics teacher education. Even so, the ‘design’ of mathematical tasks is perceived in different ways: sometimes seen as something distinct from the teaching and learning process, and sometimes as integral to it. Whilst task design has often been carried out by designers or mathematicians (perhaps as textbook authors), the focus for this review article is research that has involved mathematics teachers as partners in the design of tasks. The article provides a state-of-the-art review of relevant literature and is presented under three headings that consider, in turn, the role of mathematical ‘tasks’; the nature of ‘task design’; and the notion of ‘partnerships for task design’ in mathematics education. Subsequently, we present current research that is providing new insights into tasks, task design, and task design partnership. Based on this, we argue that ‘task design’ needs to pay particular attention to what to design, which tools are necessary or beneficial, and under what conditions; digital tools and task resources offer particular affordances that traditional resources cannot provide; and not only do teachers benefit from being partners in task design (in terms of their professional learning) but without their involvement some aspects of task design would most likely be neglected.  相似文献   

Longitudinal Analysis of Intrinsic Motivation and Competence Beliefs: Is There a Relation Over Time?     

Spinath B  Steinmayr R 《Child development》2008,79(5):1555-1569

The present study explored whether competence beliefs and intrinsic motivation for different school domains show reciprocal effects over time. A sample of 670 German elementary school pupils (M= 8.8 years, SD= 0.51) was followed over 1 year. At 4 measurement occasions, children completed self-reports on their intrinsic motivation and competence beliefs for math, German, and school in general. Latent growth models revealed that intrinsic motivation and competence beliefs decreased over time. Comparing correlational and cross-lagged structural equation models yielded only weak evidence for cross-lagged influences between the 2 constructs. Results suggest that the developmental curves of competence beliefs and intrinsic motivation might be less inextricably interwoven than frequently assumed.  相似文献   

Learning through a familiar language versus learning through a foreign language—A look into some secondary school classrooms in Tanzania     

Birgit Brock-Utne 《International Journal of Educational Development》2007

This article builds on 30 h of observations made in classrooms in secondary schools in Tanzania in the fall of 2004. The article presents an empirical study using an experimental group that was taught in Kiswahili and a control group taught the same topics in English. The author takes the reader straight into some of the classrooms and gives excerpts from four lessons. In the classrooms the teacher teaches a topic on one occasion in English and then the same topic is taught in Kiswahili. In one of the examples given here it is the same teacher who teaches the same topic in the two languages to two different classes. The observational data are examined using a theoretical framework known as qualification analysis. The data are analysed with respect to the qualification categories that are promoted or inhibited through the class-room interaction taking place. The data show that if the aim is the stupidification of the Tanzanian labour force, the use of English, a foreign language to the students and a language poorly mastered by the teachers, seems to be an excellent strategy. If the aim is to create a labour force with critical abilities and creative qualifications, the language of instruction policy is unlikely to have such an outcome.  相似文献

Ethical Boundaries among Freelance Journalists     

Birgit Røe Mathisen 《Journalism Practice》2019,13(6):639-656

This article sheds light on the professional role of freelance journalists and examines ethical dilemmas faced by Norwegian freelance journalists. Freelancers and self-employed journalists have to manage their own financial interests and secure their income, as well as the professional ethics of journalism. Finding themselves placed between autonomy and precarity, these freelancers are also engaged in non-journalistic activities, such as PR, because these kinds of jobs usually pay better than news work. This article discusses freelancers and ethical dilemmas. Further, it addresses how freelancers deal with the blurring borders between journalism and PR.  相似文献   

Theory of mind and self-control: more than a common problem of inhibition   总被引：14，自引：0，他引：14  

Perner J  Lang B  Kloo D 《Child development》2002,73(3):752-767

This study tested the theory that advances on theory-of-mind tasks and on executive function tasks show a strong correlation because the typically used theory-of-mind tasks pose the same executive demands. In Experiment 1 with fifty-six 3- to 6-year-old children, performance on the dimensional change card-sorting task as an executive function task was correlated with performance on the usual false-belief prediction task, r = .65, and the false-belief explanation task, r = .65, as measures of theory-of-mind development. Because the explanation version of the false-belief test is supposed to be free of the alleged executive demands inherent in the prediction version, the equally strong correlation with the executive function task suggests that this correlation cannot be due to common executive demands. In Experiment 2, the basic finding of Experiment 1 was replicated on another sample of 73 children, ages 3 to 5.5 years. The need for new theories to explain the developmental link between theory of mind and executive function development is discussed, and some existing candidates are evaluated.  相似文献   

Evaluation of the appropriate time period between sampling and analyzing for automated urinalysis

Introduction

Preanalytical specifications for urinalysis must be strictly adhered to avoid false interpretations. Aim of the present study is to examine whether the preanalytical factor ‘time point of analysis’ significantly influences stability of urine samples for urine particle and dipstick analysis.

Materials and methods

In 321 pathological spontaneous urine samples, urine dipstick (Urisys™2400, Combur-10-Test™strips, Roche Diagnostics, Mannheim, Germany) and particle analysis (UF-1000 i™, Sysmex, Norderstedt, Germany) were performed within 90 min, 120 min and 240 min after urine collection.

Results

For urine particle analysis, a significant increase in conductivity (120 vs. 90 min: P < 0.001, 240 vs. 90 min: P < 0.001) and a significant decrease in WBC (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), RBC (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), casts (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001) and epithelial cells (120 vs. 90 min P = 0.610, 240 vs. 90 min P = 0.041) were found. There were no significant changes for bacteria. Regarding urine dipstick analysis, misclassification rates between measurements were significant for pH (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), leukocytes (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), nitrite (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), protein (120 vs. 90 min P < 0.001, 240 vs. 90 min P<0.001), ketone (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), blood (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), specific gravity (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001) and urobilinogen (120 vs. 90 min, P = 0.031). Misclassification rates were not significant for glucose and bilirubin.

Conclusion

Most parameters critically depend on the time window between sampling and analysis. Our study stresses the importance of adherence to early time points in urinalysis (within 90 min).Key words: urinalysis, automation, analytical sample preparation methods, flow cytometry, specimen handling  相似文献   

Measuring student teachers’ practices and beliefs about teaching mathematics using the Rasch model     

Eivind Kaspersen  Birgit Pepin  Svein Arne Sikko 《International Journal of Research & Method in Education》2017,40(4):421-442

Several attempts have been made to measure and categorize beliefs and practices of mathematics teachers [Swan, M. 2006. “Designing and Using Research Instruments to Describe the Beliefs and Practices of Mathematics Teachers”. Research in Education 75 (1): 58–70]. One of the reasons for measuring both beliefs and practices is to characterize teachers in terms of the relationship between their beliefs and practices. However, the practice-instruments and the beliefs-instruments discussed in the literature are predominately based on differing constructs. Consequently, it is challenging to compare the relationship between beliefs and practices solely based on these instruments. As such, we argue that practice- and beliefs-instruments based on the same construct would be desirable when both beliefs and practices are at stake. This paper presents two Rasch-calibrated instruments that measure the level of teacher-centredness with respect to student teachers’ practices and beliefs about teaching mathematics. From a sample of 160 student teachers, 15 items have been established as being beneficial for measurement, both when the items are translated as practice items and when translated as beliefs items. By studying the invariance between both translations, we conclude that measures from both instruments can be directly compared.  相似文献
