Attrition in Online and Face-To-Face Calculus and Precalculus Courses: A Comparative Analysis

A multitude of online courses are available that provide opportunities for students to meet their higher education needs, goals, and desires in a nontraditional school setting. But, from a content specific perspective, how are students performing in online courses compared to their face-to-face counterparts? This study seeks to examine the attrition rates of online calculus and precalculus students relative to their face-to-face peers in an effort to expand the study of online mathematics pedagogy while providing course-specific data. Several studies have been conducted to explore attrition rates in relation to student demographics, STEM fields, and online course structure, but these studies do not take into consideration an acute content perspective. Focusing on calculus and precalculus while controlling compounding variables, this study seeks to answer the question: How do attrition rates in an online precalculus and an online calculus course compare to the attrition rates in a face-to-face precalculus and face-to-face calculus course

Effects of Caffeine and Vitamin E on Wisconsin Fast Plant

Sarah Ferguson examines the effects of caffeine and vitamin E on the growth of Wisconsin Fast Plant in this piece written for the Integrated Writing course BIO 3450: Concepts of Biology I for Early and Middle Childhood Education, taught by Mr. Len Kenyon at Wright State University

Backward Shift Invariant Operator Ranges

AbstractResults on first order Ext groups for Hilbert modules over the disk algebra are used to study certain backward shift invariant operator ranges, namely de Branges–Rovnyak spaces and a more general class called H(W;B) spaces. Necessary and sufficient conditions are given for the groups Ext1A(D)(H2C, H(W;B)) to vanish whereH2Cis thedualof the vector-valued Hardy module, H2C. One condition involves an extension problem for the Hankel operator with symbolB,ΓB, but viewed as a module map from H2Cinto H(W;B). The group Ext1A(D)(H2C, H(W;B))=(0) precisely whenΓBextends to a module map from L2Cinto H(W;B) and this in turn is equivalent to the injectivity of H(W;B) in the category of contractive HilbertA(D)-modules. This result applied to the de Branges–Rovnyak spaces yields a connection between the extension problem for the HankelΓB and the operator corona problem

Using Pre-Calculus and Calculus Student Work to Examine Student Problem Solving Abilities in Online and Face-to-Face Mathematics Courses

This study compares the outcomes of student learning between two pairs of courses. Each pair of courses consists of an online section and a face-to-face section. One pair of courses focuses on pre-calculus content while the second pair focuses on calculus content. Both pairs of courses are taught by the same instructor using the same course appropriate materials. Participants for this study include 9 online and 14 face-to-face pre-calculus students and 14 online and 23 face-to-face calculus students from an urban community college in the southeastern portion of the U.S. Written responses from the subjects to a collection of problems focusing on solving systems of equations and inequalities (pre-calculus) and integration (calculus) serve as the study data. Adopting a mixed method design, student work was reviewed quantitatively and qualitatively. ANOVA calculations were used to quantitatively compare scores and values earned on each question to look for differences in scores between the online and face-to-face groups. Qualitative reviews were used to analyze closely the work to evaluate problem solving approaches utilized by the students. The study revealed limited differences between the online and face-to-face groups relative to their overall score, their problem solving abilities, and their common errors. The findings of this study are consistent with findings from existing literature while offering more insights into the learning outcomes of solving systems of equations and inequalities and integration in the two different learning environments

Darkness on the Edge of Town

Darkness on the Edge of Town focuses on a series of dioramas I created accompanied by audio and video. This thesis exhibition is based on a series of interviews I conducted with a friend who is a recovering opioid addict who has spent the majority of his life incarcerated for drug offenses. The American opioid epidemic currently looms large mostly because of the influx of drug abuse in middle class white communities. My subject is of Puerto Rican descent and represents the much harsher treatment of minority addicts by the criminal justice system. His personal story represents a deep yearning to overcome his past and start anew, but also a sense of alienation from existing so long outside the bounds of society. By creating a portrait of my friend, I am also investigating the issue of addiction more broadly. My role as an artist is to convey his story, and visually recreate the memories that he has lost due to his imprisonment and addiction, while also humanizing him as a person whose basic rights have been curtailed by the system

Autism : a look into cause and treatment

This paper reviews the literature on the etiology and treatment of autism in an attempt to answer three questions. First, what are the main theories on the cause of autism? To answer this the theories of the psychoanalytic, behavioral, and biological perspectives are examined. Second, what treatment methods are available for children with autism? Ideas on treatment are discussed from each of. the three perspectives. In addition, UCLA\u27s Young Autism Project and Project TEACCH are covered. Third, what is the nature of treatment? The importance of specific treatment in the areas of language, social skills and daily living skills is reported
