We studied patterns of mothers' and fathers' differential treatment of firstborn (average age 10.5 years) and secondborn (average age 8 years) school-age siblings, and we examined the links between parents' differential treatment and children's well-being and dyadic family relationships. Mothers, fathers, and both siblings in 110 families were interviewed in their homes. For each dimension of parental behavior that we assessed (i.e., differential affection and discipline) we created groups of families that reflected mothers' and fathers' levels of differential treatment (e.g., discipline the firstborn more, equal treatment, discipline the secondborn more). Although we detected substantial correspondence between the 2 parents' differential treatment, we found a sizable group of families in which parents' reports were incongruent (i.e., 1 parent reported equal and the other differential treatment). Parental patterns were linked to differences between the siblings' well-being and both sibling and parent-child relationships, with younger siblings exhibiting greater vulnerability to differential treatment. Incongruence in differential warmth was associated with marital distress.  相似文献

Many ideas in the biological sciences seem especially difficult to understand, learn, and teach successfully. Our goal in this feature is to explore how these difficulties may stem not from the complexity or opacity of the concepts themselves, but from the fact that they may clash with informal, intuitive, and deeply held ways of understanding the world that have been studied for decades by psychologists. We give a brief overview of the field of developmental cognitive psychology. Then, in each of the following sections, we present a number of common challenges faced by students in the biological sciences. These may be in the form of misconceptions, biases, or simply concepts that are difficult to learn and teach, and they occur at all levels of biological analysis (molecular, cellular, organismal, population, and ecosystem). We then introduce the notion of a cognitive construal and discuss specific examples of how these cognitive principles may explain what makes some misconceptions so alluring and some biological concepts so challenging for undergraduates. We will argue that seemingly unrelated misconceptions may have common origins in a single underlying cognitive construal. These ideas emerge from our own ongoing cross-disciplinary conversation, and we think that expanding this conversation to include other biological scientists and educators, as well as other cognitive scientists, could have significant utility in improving biology teaching and learning.  相似文献

The study examined the extent to which a highly qualified interpreter remained parallel with or diverged from the original classroom discourse in her interpreting for a 3rd-grade deaf student in science, social studies, and resource room. The interpreter's signed and verbalized expressions were compared to the class participants' expressions for meaning equivalence. Parallel interpreting, occurring 33.2% of the time, closely matched the content of the speaker's message. Divergent interpreting, whereby the interpreter added or dropped elements of meaning, occurred 66.8% of the time. Qualitative analyses of classroom footage as well as interviews with the interpreter and the teachers revealed how, when, and why the interpreter diverged from the message. While the interpreter often made intentional reductions and additions to the discourse to achieve greater student understanding of language and course content, there was little awareness of these changes among individualized educational program team members.  相似文献

The development of response inhibition was investigated using a computerized go/no‐go task, in a lagged sequential design where 376 preschool children were assessed repeatedly between 3.0 and 5.25 years of age. Growth curve modeling was used to examine change in performance and predictors of individual differences. The most pronounced change was observed between 3 and 3.75 years. Better working memory and general cognitive ability were related to more accurate performance at all ages, but relations with speed changed with age, where better cognitive skills were initially related to slower responding, but faster responding at later ages. Boys responded more quickly and were more accurate on go trials, whereas girls were better able to withhold responding on no‐go trials.  相似文献

Nonstandard grammatical forms are often present in the writing of deaf students that are rarely, if ever, seen in the writing of hearing students. With the implementation of Strategic and Interactive Writing Instruction (SIWI) in previous studies, students have demonstrated significant gains in high-level writing skills (e.g., text structure) but have also made gains with English grammar skills. This 1-year study expands on prior research by longitudinally examining the written language growth (i.e., writing length, sentence complexity, sentence awareness, and function words) of 29 deaf middle-school students. A repeated-measures analysis of variance with a between-subjects variable for literacy achievement level was used to examine gains over time and the intervention's efficacy when used with students of various literacy levels. Students, whether high or low achieving, demonstrated statistically significant gains with writing length, sentence complexity, and sentence awareness. Subordinate clauses were found to be an area of difficulty, and follow up strategies are suggested. An analysis of function word data, specifically prepositions and articles, revealed different patterns of written language growth by language group (e.g., American Sign Language users, oral students, users of English-based sign).  相似文献

Teachers of mathematics orchestrate opportunities for interactions between learners and subject matter. Therefore, mathematics teachers need rich, multidimensional content knowledge for teaching mathematics, which incorporates knowledge of the subject matter, students, and teaching. Studying this mathematical knowledge for teaching (MKT) necessitates more than a unidirectional assessment. In this study, the mathematical knowledge for teaching reasoning and proving of two secondary mathematics teachers was investigated through classroom observations and clinical assessments. Results indicate that using MKT as a frame for examining classroom practice, in addition to assessing the MKT a teacher possesses in a clinical setting, provides an in-depth and innovative method for investigating MKT. The comparison of the two cases also identifies student positioning as a key mediating factor between MKT and opportunities to learn. Implications for using MKT as a lens for examining practice in teacher education are discussed.  相似文献

Individual differences in infant attention are theorized to reflect the speed of information processing and are related to later cognitive abilities (i.e., memory, language, and intelligence). This study provides the first systematic longitudinal analysis of infant attention and early childhood executive function (EF; e.g., working memory, inhibitory control, cognitive flexibility). A group of 5‐month‐olds (= 201) were classified as short or long lookers. At 24, 36, and 48 months of age, children completed age‐appropriate EF tasks. Infant short lookers (i.e., more efficient information processors) exhibited higher EF throughout early childhood as compared to infant long lookers, even after controlling for verbal ability (a potential indicator of intelligence). These findings are discussed in relation to the emergence of executive attention.  相似文献

Childhood maltreatment, anger, and racial/ethnic background were examined in relation to physical health, psychological well-being, and blood pressure outcomes. This study used data from a diverse sample of African American, Latino, and Caucasian participants (N = 198). Results from a series of multiple regressions indicated anger and total childhood maltreatment were robust predictors of poorer health. Although correlational analyses found maltreatment from the mother and father were associated with poorer health outcomes, when considered as part of the regression models, only a relationship between maltreatment from the mother and physical health was found. Greater anger scores were linked with lower blood pressure, particularly systolic blood pressure. Generally, more psychological and physical symptom reporting was found with greater anger scores, and higher levels of total maltreatment also predicted physical symptoms. The pattern of interactions indicated anger was more detrimental for African American participant's (and marginally so for Latino participant's) physical health. Interestingly, interactions also indicated total childhood maltreatment was related to fewer symptoms for Latino participants. Although child maltreatment may be viewed as a moral and/or human rights issue, this study provides evidence that it can also be viewed as a public health issue. Our study demonstrated that known health risk factors such as anger and maltreatment may operate in a different pattern dependent on ethnic/cultural background. The findings suggest health and health disparities research would benefit from greater exploration of the differential impact of certain moderating variables based on racial/ethnic background.  相似文献

This paper examines the use of student planners (agendas) with elementary school students. It asks how teachers, students and parents in two classrooms engage in the literacy practice of using student planners. A literacy object originally introduced to manage schoolwork in and out of school for students with learning difficulties, planners are now used widely in school districts across North America. In this cross‐case analysis, planners are shown to be used for a number of functions beyond organising students’ schoolwork. The student planners were tools through which teachers, parents and publishers extended their spheres of influence – objects used to manage others when an individual was not physically present to do so and objects used to gain entry to the classrooms and homes for particular purposes.  相似文献

In an earlier period of mass communication research, scholars were more adventuresome in advancing “new” theories and less hesitant to “create” theory. The 1970s, in particular, bore witness to the emergence of several such theories—from the knowledge gap and agenda-setting to cultivation. Scholars have generated substantial literatures elaborating work in these and other traditions. Those contributions are now sufficiently robust that it is time to direct some of our energies toward synthesizing theories. This article nominates third-person perception as a candidate for such integration. Several prominent theories of media effects in the mass communication literature are selected to illustrate how the theories can or have been integrated. Results from three surveys provided evidence that the theories of third-person perception, agenda-setting and cultivation can be interrelated. The proposition examined here can serve as a model for further integration of other media theories. This integration attempt harkened back to the times when theory building in media effects was more common and perhaps more optimistic about explaining processes of influence.  相似文献
