From Interactions to Conversations: The Development of Joint Engagement During Early Childhood

This research traces the development of symbol‐infused joint engagement during mother–child interactions into the preschool years. Forty‐nine children, who had been previously observed as toddlers (L. B. Adamson, R. Bakeman, & D. F. Deckner, 2004 ), were systematically observed during interactions with their mothers at ages 3½, 4½, and 5½ during activities related to the past and future, internal states, and graphic systems. Although the amount of symbol‐infused joint engagement reached a ceiling by 3½, its focus continued to become more complex and its form more balanced. Individual differences in children's symbol‐infused joint engagement were stable across 4 years. These findings highlight both how joint engagement is transformed as conversational skills develop and how it remains rooted in earlier interactions and supported by caregiver's actions.     

SUPERVISION IN SCHOOL PSYCHOLOGY: THE DEVELOPMENTAL/ECOLOGICAL/PROBLEM‐SOLVING MODEL

Effective supervision models guide the supervisory relationship and supervisory tasks leading to reflective and purposeful practice. The Developmental/Ecological/Problem‐Solving (DEP) Model provides a contemporary framework for supervision specific to school psychology. Designed for the school psychology internship, the DEP Model is also applicable to all pre‐service and advanced field‐based training, as well as career‐long continuing professional development. The Developmental domain initiates training at the functioning skill level of the supervisee and progresses toward independent competency. The Ecological domain addresses the multiple systemic contexts that influence school psychology practice and prepares the intern to intervene within both individual and systemic contexts. The Problem‐Solving domain focuses on the application of data‐based decision making and evidence‐based interventions to the full range of school psychology activities. It provides a systematic schema to address student, family, and school needs.     

DIRECT BEHAVIORAL CONSULTATION: EFFECTS ON TEACHERS’ PRAISE AND STUDENT DISRUPTIVE BEHAVIOR

Direct behavioral consultation is an extension of traditional behavioral consultation and focuses on assessment and training in the classroom during ongoing classroom activities. This study evaluated direct behavioral consultation services in two elementary alternative classrooms referred following a program evaluation in which data suggested behavior‐specific praise was not being delivered at a desired level. A multiple baseline design across classrooms was used to evaluate indirect and direct training procedures for increasing teachers’ implementation of behavior‐specific praise. Results indicated that indirect training did not result in substantial improvements in teachers’ use of behavior‐specific praise. Direct training procedures resulted in immediate increases in behavior‐specific praise for both teachers, but only one teacher maintained those increases immediately following training. For the other teacher, when performance feedback was added to direct training, increases in behavior‐specific praise were maintained. Data are also presented regarding student disruptive behavior. Results are discussed in terms of direct behavioral consultation theory and practice for educational settings.     

Reactions to children's transgressions in at-risk caregivers: Does mitigating information,type of transgression,or caregiver directive matter?

This study examined whether caregivers who exhibit high risk for child physical abuse differ from low-risk caregivers in reactions to transgressing children. Caregivers read vignettes describing child transgressions. These vignettes varied in: (a) the type of transgression described (moral, conventional, personal), (b) presentation of transgression-mitigating information (present, absent), and (c) whether a directive to avoid the transgression was in the vignette (yes, no). After reading each vignette, caregivers provided ratings reflecting their: (a) perceptions of transgression wrongness, (b) internal attributions about the transgressing child, (c) perceptions of the transgressing child's hostile intent, (d) own expected negative post-transgression affect, and (e) perceived likelihood of responding to the transgression with discipline that displayed power assertion and/or induction. For moral transgressions (cruelty, dishonesty, hostility, or greed), mitigating information reduced caregiver expectations that they would feel negative affect and, subsequent to the transgression, use disciplinary strategies that display power assertion. These mitigating effects were smaller among at-risk caregivers than among low-risk caregivers. Moreover, when transgressions disobeyed a directive, among low-risk caregivers, mitigating information reduced the expectation that responses to transgressions would include inductive disciplinary strategies, but it did not do so among at-risk caregivers. In certain circumstances, compared to low-risk caregivers, at-risk caregivers expect to be relatively unaffected by transgression-mitigating information. These results suggest that interventions that increase an at-risk caregiver's ability to properly assess and integrate mitigating information may play a role in reducing the caregiver's risk of child physical abuse.     

Exploring the limits of spatial memory in rats,using very large mazes

In Experiment 1, rats foraged for food in six successive phases with 8, 16, 24, 32, 40, and 48 arms attached in random locations to a large radial maze. The percentage of novel choices appeared to be determined more by spatial proximity than by number of arms. In Experiment 2, rats foraged for food in four successive phases with 8, 16, 24, and 48 arms attached to the maze in spread-out or tight configurations. Performance was poor in the tight configurations regardless of the number of arms. Performance was excellent in the 8-arm spread-out condition but declined as 16 and, then again, 24 arms were added. Thus, spatial separation, not number of locations, was the chief determinant of performance in the first two experiments. In Experiment 3, in successive phases, 8, 16, 24, 32, 40, 48, 16, and 8 food towers were set in a circle on the floor, with the spatial separation between adjacent towers held constant at 33 cm. The percentage of novel choices declined as 8 towers became 16 and did not change again with 24, 32, 40, or 48 towers in place but then increased again as 16 towers became 8. In Experiment 4, in successive phases, 8, 16, 24, and 32 food towers were set in a circle, with the spatial separation between adjacent towers held constant at 66 cm. The percentage of novel choices declined as 8 towers became 16 and again as 16 towers became 24 but did not decline further. These data were discussed in terms of the fundamental problems posed by variations in the number of food locations in the pursuit of the limit of spatial memory in rats.     

The Relationship Between Learner Characteristics and Student Outcomes in a Middle School Computing Course: An Exploratory Analysis Using Structural Equation Modeling

This study, which took place during a 7-week middle school computing course, used structural equation modeling to examine the overall cumulative relationship between self-efficacy, interest, and prior computing experience and students’ computer science learning outcomes. The findings indicated that 52% of the variance of student success, measured by a computational thinking quiz and rubric-based evaluations of participants’ computing artifacts, was related to the aforementioned learner characteristics. These findings have implications for theory and practice and suggest that future research and instructional design practice in K–12 computing education should take these learner characteristics into account.     

The nature and development of preservice science teachers' conceptions of subject matter and pedagogy

The purpose of this study was to assess the development and changes in preservice science teachers' subject matter and pedagogy knowledge structures as they proceeded through a professional teacher education program. Twelve secondary preservice science teachers were asked to create representations of their subject matter and pedagogy knowledge structures periodically (four times spanning the entirety of their subject-specific teacher education program) and participate in a videotaped interview concerning the eight knowledge structure representations immediately following student teaching. Qualitative analyses of knowledge structure representations and transcribed interviews within and between subjects were performed by one of the researchers and “blindly” corroborated by the other two researchers. Initial knowledge structure representations were typically linear and lacked coherence. Both types of knowledge structure representations were highly susceptible to change as a consequence of the act of teaching. Although there was some overlap between subject matter and pedagogy knowledge structures, they were reported to exert separate influences on classroom practice, with the pedagogy knowledge structure having primary influence on instructional decisions. Furthermore, the complexity of one's subject matter structure appeared to be a critical factor in determining whether the structure directly influences classroom practice.
