Money, sex, and drugs: a case study to teach the genetics of antibiotic resistance

The goal of the work reported here was to help students expand their understanding of antibiotic resistance, the Central Dogma, and evolution. We developed a unit entitled "Ciprofloxacin Resistance in Neisseria gonorrhoeae," which was constructed according to the principles of scientific teaching by a team of graduate students, science faculty, and instructors. A variety of activities and assessments were used, including a case study, short lectures, and group problem-solving. Implementation of "Ciprofloxacin Resistance in Neisseria gonorrhoeae" in a college freshman seminar suggests these materials are useful in increasing understanding of complex biological topics and improving problem-solving abilities.     

Structural Models for Binary Repeated Measures: Linking Modern Longitudinal Structural Equation Models to Conventional Categorical Data Analysis for Matched Pairs

The current widespread availability of software packages with estimation features for testing structural equation models with binary indicators makes it possible to investigate many hypotheses about differences in proportions over time that are typically only tested with conventional categorical data analyses for matched pairs or repeated measures, such as McNemar’s chi-square. The connection between these conventional tests and simple longitudinal structural equation models is described. The equivalence of several conventional analyses and structural equation models reveals some foundational concepts underlying common longitudinal modeling strategies and brings to light a number of possible modeling extensions that will allow investigators to pursue more complex research questions involving multiple repeated proportion contrasts, mixed between-subjects × within-subjects interactions, and comparisons of estimated membership proportions using latent class factors with multiple indicators. Several models are illustrated, and the implications for using structural equation models for comparing binary repeated measures or matched pairs are discussed.     

A test of personal and social utility values and the appeal of a career in teaching

An effective education system depends upon attracting college students into the teaching profession, but most of the research on what motivates individuals to pursue teaching merely surveys individuals who have already entered a teacher education program. This study employs an experimental design to test the effects of exposure to randomly assigned lists of reasons to teach reflecting personal utility values or social utility values on the appeal of the career to a sample of college students. Results indicate that both personal and social utility values are relevant to the appeal of a career in teaching and to a similar degree. Gender differences in this relationship were negligible.     

Using Charter Schools to Alleviate Racial Exclusion in Rural America: An Innovative Idea or a Trojan Horse?

ABSTRACT

Racial segregation has remained a lasting legacy of rural schools in southern states. Our article explains a case where community leaders created a diverse charter school to change its historical practice of an isolated White private school and isolated African American public schools. We scan documents and literature related to this integration strategy to surface key themes when using rural charter schools to alter patterns of school segregation. First, we explain pressing issues in rural schools. Second, we describe how segregation and inequality have evolved in the South. Third, we explain research showing how charter schools maintain patterns of school segregation, but with exceptions and nuances in certain contexts. Fourth, we consider the benefits and tensions surrounding one rural charter school that offers an integrated educational program. Benefits range from societal to individual as the school fosters an environment where students are exposed to diverse educational experiences. Tensions include shifting power and funding dynamics and the possibility of using a good example to shepherd in less effective charter models elsewhere.     

Learning from programmed instruction: Examining implications for modern instructional technology

This article reports a theoretical examination of several parallels between contemporary instructional technology (as manifest in one of its most current manifestations, online learning) and one of its direct predecessors, programmed instruction. We place particular focus on the unterlying assumptions of the two movements. Our analysis suggests that four assumptions that contributed to the historical demise of programmed instruction—(a) ontological determinisms, (b) materialism (c) social efficiency, and (d) technological determinism—also underlie contemporary instructional technology theory and practice and threaten its long-term viability as an educational resource. Based on this examination, we offer several recommendations for practicing instructional technologists and make a call for innovative assumptions and make a call for innovative assumptions and theories not widely visible in the field of instructional technology.     

Optimizing Conditions for Learning: Situating Refutations in Epistemic Cognition

A refutation text is designed to promote conceptual change by explicitly acknowledging commonly held misconceptions about a topic, directly refuting them, and providing an accurate explanation. In this study, we determined the impact of different types of refutation texts on adolescent readers’ conceptual change learning in science. Specifically, we manipulated the way the correct conception was justified and explained following work in epistemic cognition. Three different types of justification were compared to a control condition: justification by authority, justification by multiple sources, and justification by personal opinion. The findings showed that learning effects were optimized when the correct conceptions were presented in terms of a corroborated consensus among multiple sources.     

Does grade inflation affect the reliability of grades?

Two studies were conducted to examine the effect of grade inflation on the piling up of grades in fewer grade categories and on the reliability of grade point averages (GPAs). In all comparisons, grades were more bunched after grade inflation, which in turn, was associated with only slight, nonsignificant decreases in GPA reliability. As expected, grades were more bunched when the traditional 5-point letter scale was used than when plus and minus grades were also allowed. In the latter case as well, grade inflation seemed to have had very little effect on the reliability of GPAs. GPA reliability began to suffer, however, for graduate programs in which almost all grades were placed into just two categories, A and B.

Examining Prediction Models of Giving Up within a Resource-based Framework of Coping in Primary School Students with and without Learning Disabilities

This study tests a proposed model of coping outcomes for 290 primary school students in Years 5 and 6 (mean age = 11.50 years) with and without learning disabilities (LDs) within a resource-based framework of coping. Group-administered educational and intelligence tests were used to screen students for LDs. Students also completed a questionnaire measuring coping resources, namely student engagement and internal control as well as outcome measures of coping styles and inability to cope. Structural equation modelling revealed that student engagement promoted the use of productive coping strategies for both groups and that this relationship was partially mediated by internal control. Internal control also partially mediated the relationship between student engagement and non-productive coping for students without LDs. Furthermore, less reliance on productive and greater reliance on non-productive coping strategies, respectively, predicted more of a tendency to not cope or give up in both groups.     

Pedagogy at the brink of the post-anthropocene

Abstract

The significance of educational research is today predicated on its ability to engage with the ecological, economic, and political challenges of the anthropocene, for where we might take seriously education’s commitment to the future necessitates a sustained encounter with the implications and questions raised in the wake of ‘our’ mutated planetary ecology. To repeat in the image of those educational practices, models and patterns of thinking that have contributed to the contemporary ecological crisis of the planet falls gravely short of apprehending what it might entail to live (and die) in the contemporary moment. Yet further, where education is intimate to teleology, it is today clear that the image of the future posited educationally has fallen out of synch with the ‘outside thought’ of ecocatastrophe, or rather, our being ‘thought’ from the inhuman perspective of a planet destined to go on without us. Educationally, this threat poses a quite remarkable opportunity, for where human thought might be doomed to extinction, the question of how and where we might think assumes urgency. In this vein, this essay explores the wisdom that ‘we’ are and will be thought from perspectives alien to human desire becomes a catalyst for how educational research might be rethought otherwise in a more-than-human world.
