Using data collected in 125 seventh-grade and 56 eighth-grade Texas classrooms in the context of the “Scaling Up SimCalc” research project in 2005–07, we examined relationships between teachers’ mathematics knowledge, teachers’ classroom decision making, and student achievement outcomes on topics of rate, proportionality, and linear function—three important and cognitively demanding prealgebra topics. We found that teachers’ mathematical knowledge was correlated with student achievement in only one study out of three. We also found a lack of correlations between teachers’ mathematical knowledge and critical aspects of instructional decision making. Curriculum and other learning resources (e.g., technology, student–student interactions) are clearly important factors for student learning in addition to, and in interaction with, teachers’ mathematical knowledge. Our results suggest that mathematics knowledge for teaching may have a nonlinear relationship with student learning, that those effects may be heavily mediated by other instructional factors, and that short-term content knowledge gains in teacher workshops may not persist in classroom instruction. We discuss a need in the field for richer models of how “mathematical knowledge for teaching” works in the context of complete instructional systems.  相似文献

We examine how extended engagement in argumentation with peers leads to enhanced metalevel understanding of argumentive discourse. Following such engagement, young adolescents demonstrated enhanced understanding of counterargument and use of evidence as objectives of skilled argumentation, relative to a nonparticipating comparison group. Among the participating group, analysis of metatalk (talk about the discourse, distinguished from talk about the topic) during electronic peer dialogs proved revealing regarding participants’ evolving awareness of and adherence to discourse norms. Metatalk became more reciprocal and sustained with time and revealed an increasing focus on the argumentation process and engagement in talk that seeks to direct it. Implications are considered for understanding and studying argumentation as a social practice that encompasses not only individual skills but also the less visible norms that govern it and that members of a social group come to share.  相似文献

Abstract

A troubling gap exists between the current state of history assessment and the knowledge and skills deemed essential for students to thrive in the 21st century. We propose a new assessment of historical thinking that represents a promising alignment with extant cognitive research, as well as with the practices that undergird the discipline. In this article, we discuss the design of the Assessment of Historical Analysis and Argumentation (AHAA), as well as the accompanying scoring rubric, and report findings from our administration of multiple forms of the exam with secondary students (N?=?618). Evidence indicates that the exam captured student historical thinking about documents and that the items prompted students to construct a cognitive representation of intertextual reasoning. Given the dearth of assessments that capture student historical thinking about documents and their understanding of content, we believe the AHAA has the potential to be an important instructional resource.  相似文献

The Institute of Medicine has stressed the need for evaluations of evidence-based treatments (EBTs) for posttraumatic stress disorder (PTSD) among active duty service members (AD) using a variety of evaluation approaches (Institute of Medicine, 2012). The current study examined the clinical files of 134 service members who completed treatment for PTSD using either prolonged exposure (PE) or cognitive processing therapy at an outpatient clinic. At the completion of each session, therapists made a clinical rating as to whether or not the session was protocol adherent. The total number of treatment sessions and the proportion of sessions rated as being protocol adherent were calculated. Multi-level models estimated the change in patient PTSD and other psychological symptoms over time as a function of clinician-rated protocol adherence and total number of sessions. Approximately 65% of clinic encounters were rated by therapists as being protocol adherent. Significant reductions in PTSD and psychological symptoms were associated with protocol adherence, and this was particularly true for patients who began treatment above clinical thresholds for both PTSD and other psychological symptoms. However, as the number of sessions increased, the impact of protocol adherence was attenuated. Patient characteristics, including gender, ethnicity, and co-morbidity for other psychiatric disorders were not related to symptom change trajectories over time. These findings suggest that protocol adherence and efficiency in delivery of EBTs for the treatment of PTSD with AD is critical.  相似文献

Aim: The distribution and quality of brain recovery following pediatric arterial ischemic stroke remains controversial. The literature suggests that age at stroke may be an important modulator of neuropsychological outcome, with reports inferring either greater vulnerability or plasticity in the nascent brain. Our aim was to investigate neuropsychological outcomes following pediatric stroke in a clinical sample with reference to age at lesion, lesion laterality, elapsed time from stroke to assessment, and persistent neurological sequelae.

Methods: Using comprehensive neuropsychological assessment batteries, we investigated retrospectively a large (n?=?44) and evenly distributed group of children who had ischemic stroke during “infancy” (1 month to 1 year), “early childhood” (1 to 6 years), and “late childhood” (6 to 16 years).

Results: Children who suffered a stroke performed significantly worse on a range of neuropsychological measures when compared to a normative sample. However, children who suffered a stroke between 1 and 6 years old demonstrated better preserved neuropsychological profiles than either the earlier (before age 1) or later (after age 6) age groups. In addition, those children suffering a left hemisphere lesion performed more poorly on a range of neuropsychological measures than did children with right hemisphere lesions.

Interpretation: Age at stroke is an important determinant of recovery following insult and may modulate neuropsychological and cognitive outcome.  相似文献

When a child is offered psychotherapy, it is common that regular meetings will be offered to the parents. However, there are debates in the literature about the degree to which such parent work should include a focus on the parents’ own childhood experiences. This study aimed to examine the way that those offering parent work as part of a study evaluating the treatment of adolescent depression dealt with this issue in their work with parents, both in the study and in routine clinical practice. Design: five therapists were interviewed on the subject of working with parents’ childhood experiences within parent work parallel to child psychotherapy. Data were analysed qualitatively, using Interpretative Phenomenological Analysis. Findings: participants described the need to consider the different parameters of this work to individual adult therapy; in addition, participants felt that it was necessary to negotiate permission to work on the parents’ childhood experiences. They also spoke of making use of insight into the repetition of the parents’ history, the analysis of parental projections and offering containment within the relationship; this varies from the ‘transference work’ of individual therapy and a different style of interpretation was described. Conclusions: there is a need to give more attention to the neglected field of working with parents alongside individual child psychotherapy, especially at a time when such work is under threat within many public services. There are particular technical issues related to work with parents’ own childhood histories that are different to how one might work in individual therapy with a parent.  相似文献

Community-based participatory research (CBPR) has garnered increasing interest over the previous two decades as researchers have tackled increasingly complex health problems. In academia, professional presentations and articles are major ways that research is disseminated. However, dissemination of research findings to the people and communities who participated in the research is many times forgotten. In addition, little scholarly literature is focused on creative dissemination of research findings to the community using CBPR methods. We seek to fill this gap in the literature by providing an exemplar of research dissemination and partnership strategies that were used to complete this project. In this paper, we present a novel approach to the dissemination of research findings to our targeted communities through digital animation. We also provide the foundational thinking and specific steps that were taken to select this specific dissemination product development and distribution strategy.  相似文献

Prior knowledge in the domain of mathematics can sometimes interfere with learning and performance in that domain. One of the best examples of this phenomenon is in students’ difficulties solving equations with operations on both sides of the equal sign. Elementary school children in the U.S. typically acquire incorrect, operational schemata rather than correct, relational schemata for interpreting equations. Researchers have argued that these operational schemata are never unlearned and can continue to affect performance for years to come, even after relational schemata are learned. In the present study, we investigated whether and how operational schemata negatively affect undergraduates’ performance on equations. We monitored the eye movements of 64 undergraduate students while they solved a set of equations that are typically used to assess children’s adherence to operational schemata (e.g., 3 + 4 + 5 = 3 + __). Participants did not perform at ceiling on these equations, particularly when under time pressure. Converging evidence from performance and eye movements showed that operational schemata are sometimes activated instead of relational schemata. Eye movement patterns reflective of the activation of relational schemata were specifically lacking when participants solved equations by adding up all the numbers or adding the numbers before the equal sign, but not when they used other types of incorrect strategies. These findings demonstrate that the negative effects of acquiring operational schemata extend far beyond elementary school.  相似文献

Individuals perceive beauty as a function of physical attributes paired with the subjective experience of an object or a space. Yet, little or no research has investigated how either relational or emotional experiences shape perceptions of the physical world. Four studies were conducted to address this question using self-determination theory (Ryan and Deci in Psychol Inq 11:319–338, 2000) as a guiding framework. Studies 1 and 2 indicated that satisfaction of the needs for competence, relatedness, and autonomy in one’s childhood home was linked to perceptions of beauty directly and indirectly through emotions of the past (recollections of happiness) and present (nostalgia). Two additional studies focused on present-day spaces. In Study 3, we found that need satisfaction impacted perceptions of the university campus as beautiful. In a final study, we manipulated needs in the lab to identify a causal model of aesthetic perceptions. Findings are contextualized within the self-determination theory and perceived beauty literatures.  相似文献

The prevalence and pervasive nature of technology has fundamentally changed how individuals interact. Social networking has significantly altered communication and interaction patterns and created a dynamic venue for perpetration and victimization of bullying. A large population of middle and high school students was surveyed on perceptions and engagement in drug and alcohol usage, school violence, social networking usage, and cyberbullying victimization and perpetration. Findings indicate that although cyberbullying has many similarities to traditional bullying, there are important differences. Participation in school violence and usage of alcohol, tobacco, and illegal drugs predict both victimization and perpetration of cyberbullying.  相似文献
