Reconsidering the Character and Role of Inquiry in School Science: Analysis of a Conference

We summarize a conference on scientific inquiry bringing together science educators, cognitive scientists and philosophers of science with three goals:

Developmental Precursors of Relational Aggression From Late Childhood Through Adolescence

Relational aggression—a psychological form of aggression—has numerous negative consequences for physical and emotional health. However, little is known about the risk factors that lead youth to engage in relational aggression. Using multimethod data from a longitudinal research of 674 Mexican-origin youth, this study examined the influence of parents, siblings, and peers on the development of relational aggression. Increases in relational aggression from age 10 to 16 were associated with: (a) low levels of parental monitoring and (b) increased association with deviant peers and siblings. These results held across gender and nativity status. The findings suggest that multiple socialization agents contribute to the development of relational aggression. We discuss the practical implications for reducing relational aggression during adolescence.     

Brief Report on PROSPER Academic Outcomes: Extended Model of Crossover Effects on Young Adult College Success

This study examines crossover effects of adolescent substance misuse preventive interventions on academic success in college. It evaluates pathways of influence on college grades, via effects on school engagement, problem-solving skills, and substance misuse in high school. Data were collected as part of an Randomized Controlled Trial (RCT) evaluating a multicomponent intervention conducted in 28 school districts with middle school students. At age 19, study participants (N = 1,488) enrolled in college reported on college grades. The model fit the data, supporting hypothesized pathways of intervention impacts. Inclusion of a significant direct effect on college grades further improved model fit. Results support the potential for universal substance misuse preventive interventions delivered by community partnerships during middle school to yield effects on long-term academic success.     

Elementary teachers’ science subject matter knowledge across the teacher career cycle

Although widely touted as important, there is little evidence regarding the influence of teaching experience on elementary teachers' science subject matter knowledge (SMK). To better understand this phenomenon, we administered an assessment of science topics taught in the fifth and sixth grades to 169 preservice teachers, 231 fifth-grade teachers, and 208 sixth-grade teachers. We then compared the mean scores of teachers at different stages in the career cycle using one-way and two-way ANOVA and explored the relationship between SMK scores and years of teaching experience using regression analysis. Findings indicate that (i) being assigned to a specific grade level had an impact on teachers' SMK for topics included in the grade level, (ii) teachers' SMK scores were lower later in their careers for both science topics they had never taught and for science topics they were responsible for teaching, and (iii) results differed for fifth and sixth grades. This study adds to the existing literature through the examination of a large sample of elementary teachers, with teachers of varying years of experience, while focusing on the science topics these teachers are responsible for teaching. The results of this study provide strong evidence that (i) years of experience teaching specific science topics is associated with the development of teachers' knowledge of these topics, and (ii) teaching experience, what teachers do in the context of their everyday practice, can be an effective means of self-directed learning for teachers. There is also evidence that this influence is not uniform across years of teaching experience or science topics taught. These findings raise important implications about future research into the mechanism of SMK development through teaching experience and teacher grade-level assignments.     

Teaching science skills and knowledge to students with developmental disabilities: A systematic review

A comprehensive review of the literature was conducted to identify current practice on teaching science to students with intellectual disability (ID) and/or Autism Spectrum Disorder (ASD) in relation to two review questions—students' science outcomes and students' and teachers' experiences of the interventions. Six databases related to education, psychology, and science were systematically searched. A detailed protocol can be viewed on PROSPERO (registration number: CRD42017057323). Thirty studies were identified that reported on science interventions and 20 on student/teacher experiences of the interventions. The majority of the studies targeted science vocabulary and concepts. Other targets included inquiry skills and comprehension skills. The majority of the interventions used components of systematic instruction (n = 23). Five studies focused on self-directed learning and two on comprehension-based instruction. Students and teachers reported positive experiences of the interventions. The findings suggest that components of systematic instruction in particular might be effective in teaching science content to students with ID and/or ASD. Further research is needed to explore the effectiveness of identified interventions on teaching more complex science skills and with students with severe disabilities. Some limitations related to the search strategy are highlighted.     

Enhancement of Anatomical Education Using Augmented Reality: An Empirical Study of Body Painting

Students in undergraduate premedical anatomy courses may experience suboptimal and superficial learning experiences due to large class sizes, passive lecture styles, and difficult-to-master concepts. This study introduces an innovative, hands-on activity for human musculoskeletal system education with the aim of improving students’ level of engagement and knowledge retention. In this study, a collaborative learning intervention using the REFLECT (augmented reality for learning clinical anatomy) system is presented. The system uses the augmented reality magic mirror paradigm to superimpose anatomical visualizations over the user’s body in a large display, creating the impression that she sees the relevant anatomic illustrations inside her own body. The efficacy of this proposed system was evaluated in a large-scale controlled study, using a team-based muscle painting activity among undergraduate premedical students (n = 288) at the Johns Hopkins University. The baseline knowledge and post-intervention knowledge of the students were measured before and after the painting activity according to their assigned groups in the study. The results from knowledge tests and additional collected data demonstrate that the proposed interactive system enhanced learning of the musculoskeletal system with improved knowledge retention (F_(10,133) = 3.14, P < 0.001), increased time on task (F_(1,275) = 5.70, P < 0.01), and a high level of engagement (F_(9,273) = 8.28, P < 0.0001). The proposed REFLECT system will be of benefit as a complementary anatomy learning tool for students.     

Rhetoric and reality in science performance assessments: An update

This article addresses the rhetoric of performance assessment with research on important claims about science performance assessments. We found the following: (a) Concepts and terminology used to refer to performance assessments often were not consistent within and across researchers, educators, and policy-makers. (b) Performance assessments are highly sensitive not only to the tasks and the occasions sampled, but also to the method (e.g., hands-on, computer simulation) used to measure performance. (c) Performance assessments do not necessarily tap higher-order thinking, especially when they are poorly designed. (d) Performance assessments are expensive to develop and use: technology is needed for developing these assessments in an efficient way. (e) Performance assessments do not necessarily have the expected positive impact on teachers' teaching and students' understanding. (f) If teachers are to use performance assessments in their classrooms, they need professional development to help them construct the necessary knowledge and skills. This article attempts to address some of these realities by presenting a conceptual framework that might guide the development and the evaluation of performance assessments, as well as steps that might be taken to create a performance assessment technology and develop teacher inservice programs. © 1996 John Wiley & Sons, Inc.     

K-ABC content bias: Comparisons between Mexican American and White children

Content (item) bias on the Mental Processing Scales and the Achievement Scale of the Kaufman Assessment Battery for Children (K-ABC) was investigated with 100 Mexican American and 100 White fifth- and sixth-grade boys and girls. All children were English-speaking and from similar socioeconomic status (SES) backgrounds. An item-group (partial correlation) method that controlled for age, sex, and ability was used to examine bias. On the Mental Processing Scales, 17 (14%) of 120 items were found to be biased—the strong majority against the Mexican American children. On the Achievement Scale, it was observed that 58 (63%) of 92 K-ABC items were biased—all against the Mexican American sample. This latter finding is discussed in the context of possible differences in learning opportunities (language based, SES based, and school segregation) experienced by the two ethnic groups.
