Alternative Concussion Balance Testing Between Land & Aquatic Athletes
Sports related concussions have been a global and community health issue, with up to 3.8 million occurring in the U.S each year (Langlois et. al. 2006). Impaired postural control is one of the most common symptoms. Balance assessments have been an integral part of concussion analysis to assess if an athlete can return to play (RTP). Swimmers show significant differences in Star Excursion Balance Test (SEBT) performance compared to a normal population (Sugiura et. al. 2021). PURPOSE: This study aimed to determine if the SEBT (Plisky et. al. 2009) can assess differences in dynamic balance between land and aquatic athletes as a measure of dynamic postural stability in RTP protocols. We hypothesized that land athletes will outperform aquatic athletes on the SEBT. METHODS: Thirty healthy NCAA DIII athletes (13 male, 17 female athletes) volunteered to participate in accordance with the local IRB. Subject height, mass, and leg length were measured. Participants completed the following warm-up: 10 anterior tibialis raises, 10 squats, and 10 single leg Romanian deadlifts on each leg. After a 3-minute recovery, participants proceeded with 3 trials on each leg of the SEBT. Reach in each direction was normalized by leg length and averaged across trials. Paired t-tests in each direction compared land and aquatic athletes (jamovi v2.2.5). Repeated measures ANOVA compared all directions across both groups for each leg. Significance was set at α = 0.05. RESULTS: Athletes were (Mean±SD) 21±1.25 years old, 1.70±0.10 m tall, mass of 73.48±15.95 kg, and leg length of 0.92±0.06m. Both left (F=47.5, p\u3c.001) and right leg (F=52.1, p\u3c.001) revealed differences in directional leg excursions (Fig. 1 & 2). Left leg anteromedial excursions (Fig. 1) were greater for aquatic (85.92%) versus land athletes (81.39%, t(14) = 2.53, p=0.024). CONCLUSION: The SEBT was able to determine differences in excursion direction and between athlete populations. Land and aquatic athletes performed approximately equal in each direction, except for when aquatic athletes reached further in the anteromedial direction with the left leg. In the future, we plan to recruit a larger group and include center of pressure with the SEBT n analysis to further evaluate dynamic postural control as part of pre- and post-concussion protocol
Are there Balance Differences between Aquatic and Land Athletes?
Proficiency in static and dynamic balance tests is an indicator of both athletic proficiency as well as an indicator of movement deficiencies. Those movement deficiencies could be due to a neurological issue related to mild traumatic brain injury (i.e. concussion). Previous studies have studied single leg static balance using the BESS (Balance error scoring system) which is also used by the NCAA to pre-test for concussions (Riemann, 2012). Aquatic athletes could be at a predisposed disadvantage in NCAA concussion testing because there is a possibility of having differences in balance ability (as compared to land athletes) that may be mistaken as concussion-like symptoms. Examining the difference between aquatic and land athletes\u27 balance could help us find a better alternative for concussion testing aquatic athletes. PURPOSE: This study aimed to determine if land and aquatic athletes have different levels of inherent balance. We hypothesized that aquatic athletes would have worse balance compared to land athletes. METHODS: Thirty healthy NCAA DIII athletes (15 aquatic and 15 land athletes) volunteered in accordance with the California Lutheran University IRB. Subjects performed the BESS test while barefoot. Independent t-tests compared BESS scores for the land and aquatic athlete groups (jamovi v2.2.5). Paired samples t-test determined differences between surfaces (flat vs. foam) across the entire group. Significance for all tests was set at α = 0.05. RESULTS: There was no difference between total BESS scores for aquatic (17.13+5.35) versus land athletes (14.86+4.55, t(28)=1.25, p=.221). We found there was a difference in total BESS score between flat (4.3 +2.83) vs. foam (11.7+3.42, t(28) = 10.76, pCONCLUSIONS:The results of this study showed the BESS test is more difficult on a foam surface compared to a solid surface. The comparison of the BESS scores for land versus aquatic athletes could show differences with a larger subject pool as we saw aquatic athletes generally had higher overall BESS score. We plan to further study the BESS test with a larger sample population of athletes in a wider variety of sports
The Journal of the Center for Interdisciplinary Teaching and Learning
IMPACT: The Journal of the Center for Interdisciplinary Teaching & Learning is a peer-reviewed, biannual online journal that publishes scholarly and creative non-fiction essays about the theory, practice and assessment of interdisciplinary education. Impact is produced by the Center for Interdisciplinary Teaching & Learning at the College of General Studies, Boston University (www.bu.edu/cgs/citl).In this issue, podcasts are looked at as a pedagogical game changer. Using the award-wining podcast Serial as their catalyst, this issue's essayists look at podcast's emerging role in higher education, how multimodal learning can help students find their voices, the podcast's place in the curriculum at a criminal justice college, and how podcasts can inspire students to reflectively assess their own writing. Our reviewers take a critical look at the podcasts Welcome to Night Vale and Revisionist History

Responses to cultural diversity in Botswana’s schools: links between national policy, school actions and students’ civic equality
This article examines nation-state policies that have prioritized toleration of diversity over recognition through comparative case studies of three junior secondary schools in Botswana. Through data collected in observations, focus groups, interviews, and Participatory Action Research, we demonstrate how the schools, which varied in the ethnic composition of their students, teachers, and surrounding communities, responded differently to the reality of their multicultural student bodies. Two followed national policies closely, while the third crafted school level policies adapted to its student population, yet tightly constricted by national policies and curriculum. In all three schools, students of ethnic minority backgrounds experienced varying degrees of shame, discrimination, and a sense of exclusion from the nation and found little recourse to discuss and address these experiences within the structures of their schools. We argue that schools could better develop students’ capacity for equal citizenship were they supported by national education policies and curriculum to recognize the cultural, historical, and linguistic diversity of Botswana’s ethnic minorities explicitly in schools

Pathways toward Peace: Negotiating National Unity and Ethnic Diversity through Education in Botswana
This study examines how education can disrupt threats of conflict, specifically in the presence of
ethnic diversity. We present a historical analysis of Botswana, using methods of process tracing
drawing on documents, in-depth interviews, and Afrobarometer survey data. Post-independence
Botswana engaged in redistribution of educational access across ethnic groups and promotion of
common civic principles of social harmony. At the same time, it constructed through schools
ethnically-based national identity, which excluded many minorities. Lack of recognition for
ethnic minorities remains a persistent challenge, yet it exists in a context of high commitment to
unity and the nation-state, even among minority groups, which may have allowed recent dissent
to happen peacefully. The paper defines mechanisms by which educational redistribution and
recognition can disrupt resource-based and identity-based inequalities that often lead to conflict.
This model holds promise for conflict avoidance and mitigation in multiethnic states globally
