Factors and Interactions Influencing Technology Integration During Situated Professional Development in an Elementary School

This study examined factors that influence K–5 teachers’ technology integration efforts during a semester-long Collaborative Apprenticeship. Results suggest that shared planning time, shared curriculum, connection to an individual, expertise, physical proximity, and comfort level influenced interactions across the community of practice. Posing and responding to task-based questions, giving and seeking advice, and sharing ideas composed more than 70% of interactions between teachers. However, the nature of interactions changed as teachers assumed increased responsibility for designing technology-enhanced lessons. Teacher-leaders initially modeled exemplar applications of technology-enhanced lessons and gave advice on their classroom use. Subsequently, the community of teachers brainstormed ideas collaboratively as teacher-leaders supported peers to develop original lessons independently. Implications for collaborative apprenticeships and learning in professional environments are provided.     

Student laboratory presentations as a learning tool in anatomy education

Previous studies have shown that anatomy students who complete oral laboratory presentations believe they understand the material better and retain it longer than they otherwise would if they only took examinations on the material; however, we have found no studies that empirically test such outcomes. The purpose of this study was to assess the effectiveness of oral presentations through comparisons with other methods of assessment, most notably, examination performance. Specifically, we tested whether students (n = 256) performed better on examination questions on topics covered by their oral presentations than on other topics. Each student completed two graded, 12‐minute laboratory presentations on two different assigned topics during the course and took three examinations, each of which covered a third of the course material. Examination questions were characterized by type (memorization, pathway, analytical, spatial). A two‐way repeated measures analysis of variance revealed that students performed better on topics covered by their presentations than on topics not covered by their presentations (P < 0.005), regardless of presentation grade (P > 0.05) and question type (P > 0.05). These results demonstrate empirically that oral presentations are an effective learning tool. Anat Sci Educ 2: 260–264, 2009. © 2009 American Association of Anatomists.     

A link between students’ discernment of variation in unidirectional change and their use of quantitative variational reasoning

In this design experiment study, we investigated the problem: What conditions might foster students’ discernment of a critical aspect—variation in unidirectional change (e.g., discerning a “decreasing” increase)? At a public middle school in a large US city, we led a sequence of three days of whole class lessons, followed by task-based, clinical interviews with 14 seventh grade students (~?13 years old). Students interacted with researcher-developed dynamic computer environments, which linked filling polygon animations with dynamic graphs. We report results to demonstrate a range of students’ work along with detailed analyses of student interview episodes. We found connections between students’ predictions of graph type (linear, “mostly” linear, nonlinear), students’ conceptions of attributes represented by a graph, and students’ discernment of variation in unidirectional change. Students who discerned variation in unidirectional change also engaged in quantitative variational reasoning. To foster students’ discernment of variation in unidirectional change, task designers should provide opportunities for students to conceive of attributes as capable of varying and possible to measure.     

Physical Activity in Former Competitive Athletes: The Physical and Psychological Impact of Musculoskeletal Injury

Although competitive athletes exceed recommendations for physical activity while they are competing in sport, this does not necessarily translate into regular physical activity after retirement from sport. Research suggested the nature of competitive sport participation may not be conducive to lifelong physical activity. We propose one element of competitive sport participation that may impede physical activity post-retirement is injury. We propose that Vela and Denegar’s model of transient disablement in the physically active with musculoskeletal injuries (DPA) may be appropriate to examine the long-term consequences of sport-related injury—particularly with respect to physical activity disablement. Based on our review of literature, we propose the physical and psychological effects of injuries in sports present unique long-term barriers to physical activity in former competitive athletes. Future research could use the DPA as a foundation for assessing the long-term implications of sport-related injuries—particularly with respect to physical activity.

Three‐dimensional printing of X‐ray computed tomography datasets with multiple materials using open‐source data processing

Advances in three‐dimensional (3D) printing allow for digital files to be turned into a “printed” physical product. For example, complex anatomical models derived from clinical or pre‐clinical X‐ray computed tomography (CT) data of patients or research specimens can be constructed using various printable materials. Although 3D printing has the potential to advance learning, many academic programs have been slow to adopt its use in the classroom despite increased availability of the equipment and digital databases already established for educational use. Herein, a protocol is reported for the production of enlarged bone core and accurate representation of human sinus passages in a 3D printed format using entirely consumer‐grade printers and a combination of free‐software platforms. The comparative resolutions of three surface rendering programs were also determined using the sinuses, a human body, and a human wrist data files to compare the abilities of different software available for surface map generation of biomedical data. Data shows that 3D Slicer provided highest compatibility and surface resolution for anatomical 3D printing. Generated surface maps were then 3D printed via fused deposition modeling (FDM printing). In conclusion, a methodological approach that explains the production of anatomical models using entirely consumer‐grade, fused deposition modeling machines, and a combination of free software platforms is presented in this report. The methods outlined will facilitate the incorporation of 3D printed anatomical models in the classroom. Anat Sci Educ 10: 383–391. © 2017 American Association of Anatomists.     

Assessing collaborative computing: development of the Collaborative-Computing Observation Instrument (C-COI)

This paper describes the development, validation, and uses of the Collaborative Computing Observation Instrument (C-COI), a web-based analysis instrument that classifies individual and/or collaborative behaviors of students during computing problem-solving (e.g. coding, programming). The C-COI analyzes data gathered through video and audio screen recording software that captures students’ computer screens as they program, and their conversations with their peers or adults. The instrument allows researchers to organize and quantify these data to track behavioral patterns that could be further analyzed for deeper understanding of persistence and/or collaborative interactions. The article provides a rationale for the C-COI including the development of a theoretical framework for measuring collaborative interactions in computer-mediated environments. This theoretical framework relied on the computer-supported collaborative learning literature related to adaptive help seeking, the joint problem-solving space in which collaborative computing occurs, and conversations related to outcomes and products of computational activities. Instrument development and validation also included ongoing advisory board feedback from experts in computer science, collaborative learning, and K-12 computing as well as classroom observations to test out the constructs in the C-COI. These processes resulted in an instrument with rigorous validation procedures and a high inter-rater reliability.     

Children's patterns of preserving emotional security in the interparental subsystem

Guided by the emotional security hypothesis, this research identified (1) individual differences in children's strategies for preserving their emotional security in the interparental relationship, and (2) the psychosocial and family correlates of these individual differences. Study 1 assessed reactivity to parental conflict simulations among 56 school-age children, whereas Study 2 solicited child and mother reports of 170 young adolescents' reactions to actual marital conflict. Cluster analyses in both studies indicated that children fit three profiles: (1) secure children, who showed well-regulated concern and positive representations of interparental relationships; (2) insecure-preoccupied children, who evidenced heightened distress, involvement or avoidance, and negative representations of interparental relationships; and (3) insecure-dismissing children, who displayed overt signs of elevated distress, avoidance, and involvement and low levels of subjective distress, avoidance and intervention impulses, and negative internal representations. Results in both studies indicated that preoccupied and dismissing children experienced more interparental conflict than did secure children, and preoccupied children evidenced the highest levels of internalizing symptoms. Study 2 results indicated that dismissing children had the highest levels of externalizing symptoms and preoccupied and dismissing children reported more coping, family, and personality difficulties than did secure children.     

IMPROVING CLASSROOM ENGAGEMENT AMONG HIGH SCHOOL STUDENTS WITH DISRUPTIVE BEHAVIOR: EVALUATION OF THE CLASS PASS INTERVENTION

Off‐task and disruptive classroom behaviors have a negative impact on the learning environment and present a unique challenge for teachers to address. The aim of this study was to evaluate the Class Pass Intervention (CPI) as a behavior management strategy for secondary students with disruptive classroom behavior. The CPI consists of providing students with passes that they can either (1) use to appropriately request a break to engage in a preferred activity for a preset amount of time or (2) keep and later exchange for a preferred item or activity. Using an ABAB withdrawal design with replication through a concurrent multiple baseline across participants design, the CPI was shown to increase academic engagement, which is incompatible with disruptive behavior, in 4 students who engaged in high levels of disruptive behavior throughout the baseline condition. Results also demonstrated partial support for the durability of intervention effects over time and indicated that both teachers and students perceived the intervention to be socially feasible. Implications of the results and directions for future research are discussed.
