COMMUNITY COLLEGE MATHEMATICS INSTRUCTORS OF COLOR1 ON THE PURSUIT OF SUPPORTING DEVELOPMENTAL STUDENTS’ SELF-EFFICACY INSTRUTORES DE MATEMÁTICA DE FACULDADES COMUNITÁRIAS NA BUSCA DE APOIAR A AUTOEFICÁCIA DOS ALUNOS PROFESORES DE MATEMÁTICA DE COLEGIOS COMUNITARIOS QUE BUSCAN APOYAR LA AUTOEFICACIA DE LOS ESTUDIANTES

As of 2017, colleges in the state of Texas in the United States of America are transitioning to a corequisite model where students take developmental and traditional mathematics classes concurrently. Using a self-efficacy framework, this qualitative study aimed to explore the perceptions of four mathematics instructors of color at two community colleges in Texas that have adopted the corequisite model mentioned above. Semi-structured interviews were used to inquire how instructors perceived to best support students through this new model. Using thematic analysis, five overarching themes emerged: feelings of encouragement, vulnerability, and empathy, challenges in supporting students’ development of self-efficacy, relatedness to students. The instructors voiced many challenges in helping students. However, most of the instructors also displayed some level of attending to their student’s social and emotional needs to overcome these challenges. In many ways, instructors expressed that they have to be vulnerable with their students to overcome challenges and open themselves up so students are more willing to learn. Instructors discussed instances in which they have been oppressed, which have shaped their educator identity, influenced their current practice, and impacted their relatedness with students. Furthermore, instructors expressed constantly trying to form connections with their students. These instructors discussed how their similar social identities, such as language, race, national origin, and mathematical experiences, are an important middle ground that connects them to their students. Through relatedness and vulnerability, instructors discussed getting students to open up and become more receptive to learning, achieving the necessary outcomes to succeed. The five themes discussed in this paper foreground (a) instructors’ ability to provide student encouragement, typically through vulnerability, (b) challenges that negatively influence students’ self-efficacy and (c) relatedness and empathy to help students succeed, resulting in a higher perceived self-efficacy in their students’ part.

Chemical kindling is broadly used experimental model to investigate novel treatments on the process of epileptogenesis and coexisting behavioral comorbidities. The current study aimed to investigate the low dose perampanel (PER) (0.125 and 0.5 mg/kg) and pregabalin (PG) (15 mg/kg) as standalone treatments and in combination on kindling-induced seizure progression with concurrent electroencephalographic alterations. Mice were subjected to pentylenetetrazole (PTZ)-induced kindling followed by neurobehavioral assessment for anxiety-like activity and cognitive deficit through behavioral experiments. The monotherapy with PER at 0.5 mg/kg and PG at 15 mg/kg delayed the kindling process but PRP+PG yielded pronounced benefits and hindered the development of seizures of higher severity. PER+PG combination relieved the animals from anxiety-like behavior in various employed anxiogenic tests. Furthermore, the kindling-associated cognitive deficit was protected by PER+PG combination as increased alteration behavior, discrimination index and latencies to enter the dark zone were noted in y-maze, object recognition and passive avoidance tests, respectively while shorter escape latencies were noted in water maze. The brain samples of kindled mice had elevated malondialdehyde and reduced catalase, superoxide dismutase and glutathione peroxidase enzymes while treatment with PER and PG combination shielded the mice from heightened kindling-associated oxidative stress. Overall, the findings of the present study illustrate that concurrent administration of PER and PG effectively hindered the process of epileptogenesis by protecting neuronal excitability and brain oxidative stress. The results predict the dominance of PER and PG combination over monotherapy which might serve as an effective novel combination to combat drug resistance and behavioral disorders in epileptic patients.
