What Can the Teacher Learn in the Classroom?

Our research is concerned with teacher’s knowledge, and especially with teacher’s processes of learning, in the classroom, from observing and interacting with students’ work. In the first part of the paper, we outline the theoretical framework of our study and distinguish it from some other perspectives. We argue for the importance of distinguishing a kind of teacher’s knowledge, which we call didactic knowledge. In this paper, we concentrate on a subcategory of this knowledge, namely observational didactic knowledge, which grows from teacher’s observation and reflection upon students’ mathematical activity in the classroom. In modeling the processes of evolution of this particular knowledge in teachers, we are inspired, among others, by some general aspects of the theory of didactic situations. In the second part of the paper, the model is applied in two case studies of teachers conducting ordinary lessons. In conclusion, we will discuss what seems to be taken into account by teachers as they observe students’ activity, and how in-service teacher training can play a role in modifying their knowledge about students’ ways of dealing with mathematical problems.     

模仿、想象和重新评价：道德情感的教育

在人文科学研究的发展趋势中，所有观察者都会对情感作用做出新的正确的评价。尽管如此，“将情感教育作为道德教育的一个维度”仍是一个带有几分禁忌的话题。为证实这一点，我们提出通常未被认可、但明确适应于情感教育的三种干预方式。实施情感教育不仅是可能的，实际上也很常见。与道德行为相比，规则情感或许是衡量道德教育是否成功的一个更好的尺度。     

Who says we are not attracting the best and brightest? Teacher selection and the aspirations of Australian school students

Internationally, the quality of teachers is a growing focus of educational reform, with new policies attempting to ensure that only the ‘best and brightest’ are selected for the teaching profession. This article tests the assumption underpinning these developments that prospective teachers lack the desired academic and personal qualities. Drawing on data on the career aspirations of 6492 Australian school students in Years 3–12, we investigated who, among these students, expressed interest in teaching and their reasons for doing so. Using logistic regression, we found that interest in teaching was widespread and prior academic achievement was not a significant predictor. Thematic analysis of reasons expressed for interest in teaching indicated that working with children and/or in specific subject areas, altruism, and perceptions of personal suitability for the job dominated student responses. These data provide a counter-narrative to the primacy, in policies for teacher recruitment and selection, of needing to attract ‘better’ students. We argue that policies for improving teacher quality should also capitalise on the widespread interest in teaching among school students. Without such a discursive broadening, we caution that current attempts to attract the ‘best and brightest’ risk undermining the very goals espoused.     

Positive and negative successive contrast effects following multiple shifts in reward magnitude under high drive and immediate reinforcement

Multiple shifts in reward amount were given to rats in a straight runway. Both positive and negative contrast effects were observed. A positive contrast effect was observed, however, only if the shift from small to large reward occurred while the subject was evidencing a negative contrast effect. Implications for current conceptions of reinforcement contrast are discussed.     

Reading and Generalist Genes

ABSTRACT— Twin-study research suggests that many (but not all) of the same genes contribute to genetic influence on diverse learning abilities and disabilities, a hypothesis called generalist genes . This generalist genes hypothesis was tested using a set of 10 DNA markers (single nucleotide polymorphisms [SNPs]) found to be associated with early reading ability in a study of 4,258 7-year-old children that screened 100,000 SNPs. Using the same sample, we show that this early reading SNP set also correlates with other aspects of literacy, components of mathematics, and more general cognitive abilities. These results provide support for the generalist genes hypothesis. Although the effect size of the current SNP set is small, such SNP sets could eventually be used to predict genetic risk for learning disabilities as well as to prescribe genetically tailored intervention and prevention programs.     

离散家庭

Dad and Mum have split up for eternity,They will still remain together in my heart.There are so many happy memories in the past,And When I play them over and over again,It's like them beqinning from the end,back to the start。We did stuff as if we were the happiest familly in the worId,I would have never picked this to happen with my parents.We'd go out to the cinemas and go camping and everywhere else,No matter if it were hot or cold.     

Children's Relationships with Peers: Differential Associations with Aspects of the Teacher-Child Relationship

Associations between children's social competence with peers and differential aspects of their teacher-child relationships were examined in a longitudinal sample of 48 4-year-old children enrolled in child care as infants. Toddler security with teacher was negatively associated with hostile aggression and positively with complex peer play and gregarious behaviors. Prosocial behaviors and withdrawing behaviors were associated with preschool security with teacher. Dependence on teachers as a preschooler was associated with social withdrawal and hostile aggression. Positive toddler teacher socialization was associated with higher perceived peer acceptance. Preschool teacher negative socialization was negatively associated with complex peer play, teacher ratings of hesitancy, friendly enactment, and accidental attribution and positively related to teacher ratings of difficulty.
