Molecular Interaction of Imidazolium-based Ionic Liquids with a DNA-Oligonucleotide
No full textA self-complimentary 14-mer (7-TA) double stranded DNA oligonucleotide and a representative set of ILs from the imidazolium family were selected to determine the degree to which the ILs intercalate within the DNA. Steady-state and time-resolved fluorescence measurements were made using the dye 4,6-diamidino-2-phenylindole (DAPI) in buffer solutions with varying IL concentrations. DAPI was selected because it is known to bind to the minor groove of AT-rich sections of DNA. Various control experiments were made against which we compared the results from DNA/IL solutions. Steady-state excitation and emission spectral maxima shift for DAPI/DNA in the presence of the C16mim and C10mim ILs. This shows that both of these ILs bind to the minor groove of the DNA and displace the DAPI. The observed thresholds for IL concentration were ~5µM and ~40µM, respectively. The C4mim had no significant effect on the DAPI/DNA complex. Time-resolved measurements also support the conclusion that ILs displace DAPI from the minor groove, though apparently at a lower IL concentration threshold than the steady-state measurements suggest. The lifetime and anisotropy time constants suggest that the IL threshold concentrations are ~3µM and ~10 µM. Differences between the threshold concentrations will be discussed.https://digitalcommons.brockport.edu/research_posters/1043/thumbnail.jp
Implementing Translanguaging with Multilingual ELLs in the Science Classroom
No full textAbstract
My experience working with teachers with little or no experience working with ELLs inspired the development of this capstone. This experience directed me to identify the problem I am addressing in this capstone. How can general education teachers implement translanguaging in science curriculum to support ELLs? Many content area teachers have not been formally trained in language acquisition strategies. For this reason, ELLs face linguistic and social emotional challenges as well as underperformance on assessments. For this reason, chapter 3 of this capstone is a PD in translanguaging targeted for middle school science teachers. The studies evaluated in this capstone revealed that translanguaging promotes the development of ELL students’ academic and social language. Findings also showed that teachers used various translanguaging strategies in their classrooms to develop ELL students’ comprehension, ability to engage in complex texts, content-based writing and their understanding of science content. Implications from the research point toward content area teachers needing to be formally trained and supported in using translanguaging with ELLs.

Critical Literacy in Literature Instruction: Canonical vs. Young Adult Literature
No full textStudent populations are increasing in all forms of diversity: race, ethnicity, religion, socio-economics, gender, sexuality, ability, and more. They are becoming increasingly heterogenous. However, ELA literature curriculums remain largely homogenous. This is due to the fact that ELA classrooms typically teach from the traditional literary canon and text exemplars that contain mainly white, male, heterosexual, Christian, and physically- and mentally-abled authors and narratives. To counter the dominant narrative, educators can and should adapt a pedagogical approach to contemporary literature instruction that promotes critical literacy with paired canonical and young adult literature text sets and essential questions
Effective Strategies for Reducing Sedentary Lifestyles of Adolescent Youth
No full textAs society continues to evolve and adopt new ways of performing tasks, so have the people. In years past, children played outside with friends, entertained themselves, and walked to get where they were going. Children were physically active through play. Now more than ever, children are becoming complacent. They would prefer to play inside on a game console or computer rather than hang out with friends and play outside. It has been found that childhood obesity has a direct correlation with the overuse of electronic devices and children who live sedentary lifestyles (Granich et al., 2011). Barriers, such as a lack of parental involvement and unsupervised leisure time, have allowed adolescents the freedom to spend their time overly engaged in screen time activities and less involved in daily recommended physical activity (PA) (Abarca-Sos et al., 2016). The purpose of this synthesis was to review the literature on effective strategies for reducing sedentary lifestyles in adolescent youth
Factors Impacting Enjoyment in Physical Education for Children with Disabilities
No full textStudents with disabilities have lower levels of physical activity compared to typically developing peers, which can impact the development of motor competence needed to enjoy lifelong physical activity. Enjoyment has been linked participation in physical activity. Thus, the purpose of this synthesis was to discover factors that impact enjoyment in physical education for children with disabilities. After a thorough search of the available literature, 10 research articles met the inclusion criteria and were included in the critical mass. Factors contributing to enjoyment in physical education for children with disabilities were intrinsic and extrinsic. Extrinsic factors contributing to enjoyment included interaction with peers and teachers while intrinsic factors included perceived motor ability and activity preference. Recommendations for teachers to increase enjoyment in physical education for students with disabilities includes using affective inclusive practices, creating a positive environment, and increasing teacher readiness and attitude. Future research should be done on how to provide appropriate training to current teachers and students in physical education teacher education programs to increase levels of enjoyment in physical education for students with disabilities
CAN PHYSICAL ACTIVITY BENEFIT MENTAL HEALTH? A SYNTHESIS OF LITERATURE
No full textThe purpose of this synthesis is to examine the benefits of physical activity, as opposed to prescription medication, on mental health, specifically the diagnosis of depression and anxiety. Within this synthesis there is research done showing data of overprescribing and a lack of healthy treatment options from this generation’s medical professionals. The studies reviewed within the critical mass highlight many factors bringing positive data to using physical activity as a treatment for depression and anxiety in many different types of ways. Studies were reviewed through the length of intervention, type of intervention, based on participant’s symptoms and medication levels. The participants were looked at through the course of using physical activity through their knowledge/interest of activity, ideas for activity, guidance for activity etc. in the hopes that physical activity will become a lifelong treatment option for their diagnosis as opposed to prescription medication. It is the hope that future research continues to gather data to support this topic and spread awareness of it for a healthier future for both the mind and the body.

Does Reducing Supervision for Low-risk Probationers Jeopardize Community Safety?
No full textTHE NUMBER OF individuals on community supervision in the U.S. far surpasses those incarcerated. Of the 6.6 million adults in 2016 under correctional control, more than 4.5 million (68 percent) were serving a term of community supervision Eighty-one percent of the individuals placed on community supervision were probationers ( With large numbers of individuals supervised on probation, agencies must explore how to allocate resources more wisely, all while meeting the mandate for enhanced public safety
Equasher: The educational app designed to support the concept of equality in equation solving
No full textEquation solving is an essential skill that gains complexity as students progress through secondary mathematics. Many students struggle to learn the basic principles of solving equations. Others have difficulties working with specific types of expressions and equations. Equasher, an interactive application that provides real-time feedback to support problem solving, was created to address these challenges. Equasher is a fully functional calculator for solving equations designed to foster conceptual understanding and problem-solving skills. Equasher aims to reduce the user’s cognitive load and eliminate errors in algebraic manipulation so that the user can develop feasible equation solving strategies. Secondary mathematics teachers could implement Equasher as a tool to guide inquiry, promote self-reflection, or accommodate students with disabilities
The Female Athlete Triad and It’s Long-Term Effect on High School Female Athletes
Get PDFWith the passage of Title IX in 1972, females have come a long way in regards to sport participation. This was something that was considered great for women and has led to the tremendous increase in female participation in sports in high schools. While participation in sports has many benefits, one unforeseen consequence was the emergence of the female athlete triad. The female athlete triad is a composed of three things, low-energy availability (disordered eating), menstrual irregularities, and negative effects on bone mineral density. The purpose of this synthesis was to review the literature on the female athlete triad and its long-term effect on high school female athletes
Physical Activity and its Impact on Cognitive Development
Get PDFThe educational system largely is associated with academic assessments and sitting at a desk or on a computer for a majority of the school day. Another part of the education system that is often overlooked is caring for the child health and well-being. Education is more than tests and homework and can be facilitated by other methods that don’t encourage a sedentary lifestyle. The purpose of this synthesis project is to determine what impact physical activity can have on cognitive development, cognitive function and overall brain health. Results have shown that even a single bout of exercise can have a positive impact on cognitive function. The research analyzed for this synthesis project has revealed a great deal of evidence that suggests that cognitive development is positively impacted by physical activity
