Description
An intervention study was conducted with elementary physical education teachers and their use of a newly developed series of fitness segments called Knowledge in Action (KIA). This study was designed to enable teachers to teach healthy behavior knowledge (HBK) in their classes without sacrificing physical activity levels. This study has two phases. First, the intervention was conducted to determine the effectiveness of the KIA fitness segment intervention. Second, teachers' perceptions of both teaching HBK and the KIA fitness segments were investigated. Ten teacher participants were randomly assigned to the intervention or control group. Intervention teachers participated in professional development, provided with all teaching materials, and YouTube videos that modeled the teaching of the KIA fitness segments. Teacher fidelity was measured through observations. Student physical activity patterns were measured in randomly selected teachers' classes (both intervention and control) to determine potential physical activity pattern differences between groups. Teachers were interviewed from one to three times across the project in order to determine perceptions of teaching HBK and the KIA fitness segments. Researchers used constant comparison method to uncover possible common themes. Student knowledge was assessed pre/post using PE Metrics Standard 3 cognitive test to determine HBK changes. Data analysis included General liner models (GLM) at the student level (gender) and Hierarchical linear models (HLM) at the school level (treatment, school). There was a moderate mean teacher fidelity score (77.9%) found among the intervention teachers. HLM results showed students in the intervention group had a 3.4(20%) greater improvement in HBK scores when compared with their control counterparts (p<0.001). Student activity levels were found to be similar in both groups with 871.33 and 822.22 steps in the intervention and control groups, respectively. Although all of the teachers thought it was important to teach HBK they were not spending time on it during classes at pretest. Three common themes were discovered: (a) Effective Teacher Training of the Segments, (b), Teachers Learned a Novel Strategy, and (c) Teachers Recommended Modifications. In summary, the KIA fitness segments received favorable views and gave teachers a way to teach HBK without reducing physical activity time.

Description
How is knowledge created at the intersections between basic science, biotechnology, and industry? Gene drives are an interesting example, as they combine a long-standing interest with a recent technological breakthrough and a new set of commercial applications. Gene drives are genes engineered such that they are preferentially inherited at a frequency greater than the typical Mendelian fifty percent ratio. During the historical and conceptual evolution of gene drives beginning in the 1960s, there have been many innovations and publications. Along with that, gene drive science developed considerable public attention, explosion of new scientists, and variation in the way the topic is discussed. It is now time to look at this new organization of science using a systematic approach to characterize the system that has enabled knowledge to grow in this scientific field. This project breaks new ground in how knowledge advances in genetic engineering science, and how scientists understand what a “gene drive” is through analysis of language, communities, and other social factors. In effect, this research will advance multiple fields and enable a deeper understanding of knowledge and complexity. This project documents patterns of publication, collaborative relationships, linguistic variation, innovation, and knowledge expansion. The results of computational analysis provide an in-depth and complete characterization of the structure, dynamics, and evolution of scientific knowledge found in the gene drive technology. Further, time series analysis of the multiple layers of discourse enabled a diachronic connective mapping of collaborative relationships and tracked linguistic variation and change, highlighting where ambiguous language may appear, improving and creating more cohesive scientific language.
Overall, depicting the structure, dynamics, and evolution of scientific knowledge during a novel eruption of scientific complexity can shed light on the factors that can lead to: (1) improved scientific communication, (2) reduction of scientific progress, (3) new knowledge, and (4) novel collaborative relationships. Therefore, characterizing the current technological, methodological, and social contexts that can influence scientific knowledge.

Description
Physical activity (PA) has been shown to increase cognitive function, with higher test scores being reported for students engaged in higher levels PA. Additionally, the integration of the Common Core content into physical education allows for more Common Core content practice while students meet physical education objectives. Integration can be defined as the teaching of two or more subject areas simultaneously to enhance students’ learning and understanding. This novel shift to integration is underpinned by Fullan’s Change Theory where students may learn content in new and meaningful ways that meet the goals of multiple realms in education. The purpose of this crossover, replication design study was to investigate first-grade students’ enjoyment levels (enjoyment exit slips), attitudes (pre- & post-surveys), step counts (accelerometers), reading and listening comprehension (Accelerated Reader testing), as well as students’ and teachers’ perceptions (interviews & field notes) when integrating children’s literature into the fitness segment of physical education. Twenty-one first-grade students, two first-grade classroom teachers, and two physical education teachers from two different schools (Private and Public) in Southwestern, US participated in this study for six weeks each (12 weeks across the two schools). At each school, one first grade class participated as both the control and intervention groups. Overall, the results from integrating children’s literature into the physical education fitness segment were positive. Students’ enjoyment levels were high, their attitudes remained positive, they maintained similar step counts throughout the intervention periods, and the students scored similarly on the Accelerated Reader assessments from content taught in the classroom versus content presented in physical education. Additionally, students’ and teachers’ perceptions were positive, underpinned by Fullan’s Change Theory and resulted in the following three themes for students: (a) Motivation and engagement, (b) learning as perceived by students, and (c) home environment, as well as the following two themes for teachers: (a) Motivation and resources, and (b) stay the course. To my knowledge, this is the first experimental investigation of the integration of children’s literature into physical education which provides necessary evidence and an invaluable start to this important line of inquiry.
