Effects of public day-care: a longitudinal study   总被引：1，自引：0，他引：1  

B E Andersson 《Child development》1989,60(4):857-866

119 Swedish children were followed from their first year of life up to the age of 8. Most could be classified according to (a) type of day-care they had experienced during their first 7 years of life and (b) time of first entrance into day-care. At 8 years, the children were tested with aptitude tests and rated by their teachers on school performance and social and personal development. Hierarchical regression analyses and MANCOVAs were used in the statistical treatment. Time of entrance into day-care predicted children's cognitive and socioemotional development, controlling for sex and home background. Children with early day-care (entrance before the age of 1) were generally rated more favorably and performed better than children with late entrance or home care. There was a tendency for early center care to predict a more favorable outcome than other care.  相似文献   

What Should Govern Teacher Education? The Impact of Unclear Governmental Prescriptions: Is there something more effective?     

Catharina Andersson 《欧洲师范教育杂志》2002,25(2-3):251-262

This article begins with a historical introduction to Swedish teacher education and continues with an investigation concerning a new teacher education that started in 1988 for primary and middle-school teachers, educated to teach grade 1-7 'grundskolla¨rare'. This teacher education is analysed and interpreted through paradigms constructed out of To¨rnebohm's paradigm concept idea. Four paradigms are used: the traditional craft paradigm, the academic, the progressive, critical-social and the personalistc paradigm. The article ends with a short discussion concerning teacher education regulated and controlled by politicians and the problems for teacher educators.  相似文献   

Student Collaboration in Group Work: Inclusion as Participation     

Karin Forslund Frykedal  Eva Hammar Chiriac 《International Journal of Disability, Development & Education》2018,65(2):183-198

Group work is an educational mode that promotes learning and socialisation among students. In this study, we focused on the inclusive processes when students work in small groups. The aim was to investigate and describe students’ inclusive and collaborative processes in group work and how the teacher supported or impeded these transactions. Social Interdependence Theory was utilised as the theoretical perspective overarching the study. The observational data employed were collected by video-recording group work. A part of Black-Hawkins framework of participation was used to define inclusion and for the analysis of inclusive and collaborative processes. The results suggest that students’ active participation in the discussions around the group work structures and analytical discussions, together with the teacher’s more defined feedback and avoidance of the traditional authoritative role, are examples of prerequisites for group work to be enacted in an inclusive manner.  相似文献   

Maintaining Competence in the Initial Occupation: Activities among Vocational Teachers     

Per Andersson  Susanne Köpsén 《Vocations and Learning》2018,11(2):317-344

Contemporary work-life changes rapidly, and vocational education and training (VET) teachers need to keep up-to-date with changing knowledge demands and technological developments. This article concerns VET teachers’ continuing professional development (CPD) related to the specific vocations for which they teach. The aim is to analyse VET teachers’ participation in various types of activities designed to make them become more knowledgeable in relation to industry currency. The study draws on a socio-cultural perspective on practice and learning. Theory concerning adults’ participation in education is also used in analysing drivers of and barriers to participation in learning activities. The analyses are based on survey data from 886 Swedish VET teachers relating to their participation in different activities, barriers/drivers concerning participation in these activities, perceived effects (outcomes) of participation in terms of professional development, and teachers’ background. Reading professional texts was the most common CPD activity among those VET teachers participating in the study. Reading, and work in the VET teacher’s former/initial occupation were the two activities where variation in performing them could be explained to the highest degree. The study particularly highlights the importance of boundary crossing between school and work-life for maintaining and developing the industrial currency of VET teachers’ competence. Active membership and engagement in the community of practice of the initial occupation is important for participation in CPD activities closely related to this community.  相似文献   

Taking Stock and Moving Forward: Lessons From Two Plus Decades of Research on the Milwaukee Parental Choice Program     

Michael R. Ford  Fredrik O. Andersson 《Journal of School Choice》2019,13(2):158-176

In this article we review the substantial literature on the Milwaukee Parental Choice Program (MPCP), the U.S.’s oldest and largest urban school voucher program, and use the review to propose an agenda for second generation school voucher research. We review research on student-level impacts, public school response, parental decision-making, fiscal impacts, organizational churn, and the larger public policy issues resulting from Milwaukee’s voucher policy. We conclude that the balance of literature on the MPCP shows limited positive effects for voucher users, positive fiscal impacts for taxpayers, substantial numbers of school closures, and various externalities that need to be better understood given the program’s size and prominence. Given this, we suggest a future research agenda focused on the question of how to make voucher policies as successful as possible.  相似文献   

How Swedish pupils,aged 12‐15 years,understand light and its properties‡     

Björn Andersson  Christina Kärrqvist 《International Journal of Science Education》2013,35(4):387-402

The reasoning patterns used by a sample of Western Australian secondary school students aged 13‐16 were investigated with regard to the following reasoning modes: proportional reasoning, controlling variables, probabilistic reasoning, correlational reasoning, and combinatorial reasoning.

There was a wide range in students’ reasoning abilities at all year levels. Large percentages of students did not use formal operational reasoning patterns when they attempted to solve problems assessing their ability to use each of the five reasoning modes. Commonly used, but incorrect reasoning patterns were identified for each reasoning mode.

The students’ ability to use formal reasoning patterns was found to be an important factor in determining student achievement in lower secondary science, in their selection of year 11 science subjects, and their achievement in these subjects.

The results of the study indicate that it is important for teachers to be aware of the reasoning patterns of their students and the cognitive demands of course content, so that they can optimally match the content and their teaching strategies with the abilities of their students. Further research is needed to establish the nature of instruction which might best facilitate cognitive growth.  相似文献   

Generalized Linear Factor Score Regression: A Comparison of Four Methods     

Gustaf Andersson  Fan Yang-Wallentin 《Educational and psychological measurement》2021,81(4):617

Factor score regression has recently received growing interest as an alternative for structural equation modeling. However, many applications are left without guidance because of the focus on normally distributed outcomes in the literature. We perform a simulation study to examine how a selection of factor scoring methods compare when estimating regression coefficients in generalized linear factor score regression. The current study evaluates the regression method and the correlation-preserving method as well as two sum score methods in ordinary, logistic, and Poisson factor score regression. Our results show that scoring method performance can differ notably across the considered regression models. In addition, the results indicate that the choice of scoring method can substantially influence research conclusions. The regression method generally performs the best in terms of coefficient and standard error bias, accuracy, and empirical Type I error rates. Moreover, the regression method and the correlation-preserving method mostly outperform the sum score methods.  相似文献   

Perceptions of school and future adjustment to life: A longitudinal study between the ages of 18 and 25   总被引：1，自引：1，他引：0  

Bengt-Erik Andersson  Kerstin Strander 《Scandinavian Journal of Educational Research》2013,57(5):459-476

A group of senior high school students, 18 years old, answered a questionnaire about their perceptions of their school situation. Around one-third of the group seemed to like school very much and another third seemed to hate or dislike school very much. This group was followed up until they were 25 years old. Of the original sample 82%, 462 persons, answered a new questionnaire about how they had succeeded in life, what kind of further education they had got, what kind of job they had, how they looked upon their future job and life careers, etc. They were also asked about their memories and feelings about their former school experiences. In the analyses we relate the students' school perceptions at age 18 to their memories of school when 25. A substantial number of the respondents remembered school in the same way as they perceived school when in school. Those who hated school seemed to be more vulnerable when they were adult. We also discuss what could be done to change school so that it does not loose one-third of its students. We introduce the concept of the 'learning centre', the aim of which is to teach the joy of learning and stimulate the students' thirst for knowledge.  相似文献
