Background: Childhood obesity is one of the most serious public health concerns in the United States and has been associated with low levels of physical activity. Schools are ideal physical activity promotion sites but school physical activity opportunities have decreased due the increased focus on academic performance. Before-school programs provide a good opportunity for children to engage in physical activity as well as improve their readiness to learn. Purpose: The purpose of this study was to examine the effect of a before-school running/walking club on children's physical activity and on-task behavior. Methods: Participants were third and fourth grade children from two schools in the Southwestern United States who participated in a before-school running/walking club that met two times each week. The study employed a two-phase experimental design with an initial baseline phase and an alternating treatments phase. Physical activity was monitored using pedometers and on-task behavior was assessed through systematic observation. Data analysis included visual analysis, descriptive statistics, as well as multilevel modeling. Results: Children accumulated substantial amounts of physical activity within the before-school program (School A: 1731 steps, 10:02 MVPA minutes; School B: 1502 steps, 8:30 MVPA minutes) and, on average, did not compensate by decreasing their physical activity during the rest of the school day. Further, on-task behavior was significantly higher on days the children attended the before-school program than on days they did not (School A=15.78%, pseudo-R2=.34 [strong effect]; School B=14.26%, pseudo-R2=.22 [moderate effect]). Discussion: Results provide evidence for the positive impact of before-school programs on children's physical activity and on-task behavior. Such programs do not take time away from academics and may be an attractive option for schools.

The Accelerated Reader Program has been a widely used reading program in elementary schools in the United States. However, even with its popularity, there have been controversies on if and how it should be used in the classroom. Arguments in support say the program gets children to read and that it is a helpful tool for teachers to keep track of each students reading abilities. Arguments against suggest that book choice is decreased, book levels are askew, the quizzes do not promote higher level thinking, and the use of incentives may send the wrong signals to students. Schools have started to abandon the program in the recent years, but maybe it will come back bigger and stronger. In the meantime, schools need to make sure that enriching books fill the schools and classrooms to promote reading for their students.

For some children, peer victimization stops rather quickly, whereas for others it marks the beginning of a long trajectory of peer abuse (Kochenderfer-Ladd & Wardrop, 2001).

For some children, peer victimization stops rather quickly, whereas for others it marks the beginning of a long trajectory of peer abuse (Kochenderfer-Ladd & Wardrop, 2001). Unfortunately, we know little about these trajectories and what factors may influence membership in increasing or decreasing victimization over time. To address this question, I identified children's developmental patterns of victimization in early elementary school and examined which child-level factors influenced children's membership in victimization trajectories using latent growth mixture modeling. Results showed that boys and girls demonstrated differential victimization patterns over time that also varied by victimization type. For example, boys experienced more physical victimization than girls and increased victimization over time was predicted by boys who display high levels of negative emotion (e.g., anger) towards peers and low levels of effortful control (e.g., gets frustrated easily). Conversely, girls exhibited multiple trajectories of increasing relational victimization (i.e., talking about others behind their back) over time, whereas most boys experienced low levels or only slightly increasing relational victimization over time. For girls, withdrawn behavior lack of positive emotion, and displaying of negative emotions was predictive of experiencing high levels of victimization over time.

This study explored the science learning experiences of elementary English Language Learners (ELLs) in a fourth-grade mainstream science classroom in an urban setting. Informed by ethnographic research and case study design, this study interrogated the celebrated and marginalized practices within common classroom procedures and what science-related identities the focal ELLs developed within classroom interactions through the lens of identity as position. Additionally, this study examined how the focal ELLs perceived themselves as science learners and how they affiliated with what scientists do and school science. Data collection lasted for two months and included video recordings of science instruction and classroom interactions, interviews with the focal ELLs, and students’ artifacts. Findings revealed that “doing science” in this fourth-grade science classroom was narrowly defined, as the celebrated practices involved mainly following the classroom behavioral codes and telling the right answer to the teacher’s questions. Findings also showed that the three focal ELLs complied with the celebrated practices to various degrees and were positioned marginally or negatively by the teacher and peers. The marginal and negative positioning affected the focal ELLs’ opportunities to engage meaningfully in classroom learning activities. Finally, findings regarding the focal ELLs’ perceptions of themselves as science learners showed the various ways in which they used their experiences inside and outside the classroom to construct their understanding of and relations with scientists and the science subject. This study provided implications for student science identity research and practice for supporting ELLs in the mainstream science classroom.
