Empirical validation of a modern genetics progression web for college biology students

ABSTRACT

Research in learning progressions (LPs) has been essential towards building understanding of how students’ ideas change over time. There has been little work, however, into how ideas between separate but related constructs within a multi-faceted LP relate. The purpose of this paper is to elaborate on the idea of progression webs to model connections within and between related constructs simultaneously, and to explain and demonstrate the efficacy of path analysis towards validating a hypothesised progression web for understanding of modern genetics. Specifically, we evaluate strength of evidence for a progression web based upon multiple related constructs within a multi-faceted LP describing undergraduate biology students’ understanding of genetics. We then utilise the progression web to generalise theory around how undergraduate students understand relationships between related genetics concepts, and how they use simpler concepts to scaffold those which are more complex.     

Masculine generics=sexist language: A review of literature and implications for speech communication professionals

This article reviews empirically based studies demonstrating gender‐biased perceptions resulting from use of “man”‐linked words (e.g., “mankind”) and third‐person‐singular masculine pronouns. Contrary to commonsense beliefs, neither of these linguistic conventions has been found to he associated with equal likelihood perceptions of female and male referents. Specific suggestions are made for the adoption of alternatives to masculine generics in speech and communication teaching and research reportage. Also, suggestions are made for research and development activities.     

Investigating Personality and Viewing-Motivation Correlates of Reality Television Exposure

This study investigated the personality and viewing-motivation correlates of reality television exposure. Results from a survey of 592 undergraduates showed that extroversion negatively predicted reality television exposure, whereas neuroticism was not associated with it. Both instrumental (social interaction, information, and arousal) and ritualized (relaxation, pass time, entertainment, and companionship) viewing motivations positively predicted exposure to reality television. A two-stage model by which personality traits contributed to viewing motivations, which, in turn, contributed to the selection of reality television, was tested and offered an adequate fit to the data. Implications for uses and gratifications research are discussed.     

Phonological skills and comprehension failure: A test of the phonological processing deficit hypothesis

Shankweiler and colleagues argue that text comprehensionproblems in young children arise from phonological processingdifficulties. Their work has focused on children with poor wordreading ability. We investigated this hypothesis for children whoexperience comprehension difficulties in the presence of age-appropriate word reading skills. We found that good and poorcomprehenders performed comparably on various measures ofphonological processing and differed on a task that made greaterdemands on working memory, Bradley and Bryant's odd-word-outtask. In a final study, hierarchical regression analyses supportedthis distinction: the odd-word-out task was a strong predictor ofreading comprehension performance even after IQ, vocabulary and single word reading had been controlled for, but a lessmemory-dependent phonological task was not. These studiessupport previous work which indicates that poor comprehenders'problems arise from higher-level processing difficulties.     

Investigating the causes of reading comprehension failure: The comprehension-age match design

The reading-level (or reading-age) match design has become a widely-used tool for investigating the possible direction of the relation between particular skills and word reading ability: Cause or consequence. This paper outlines an analogous method for identifying candidate causes of reading comprehension failure, the `comprehension-age match design' and discusses the strengths and limitations of this design.     

Guilt, Suffering and Responsibility

This paper examines the moral significance of guilt in the context of how students confront the suffering of another. Within social-justice education, such confrontations are often staged in pedagogical efforts to encourage students to assume social responsibility. Frequently, however, the guilt that students claim to endure as a result of these pedagogical encounters is not perceived to be of much ethical import. By exploring the psychoanalytic work of Melanie Klein and the ethical philosophy of Emmanuel Levinas, this essay argues that guilt arises out of our susceptibility to another's pain and that it plays a crucial role both in 'making reparation' (Klein) and in the very formation of responsibility itself (Levinas).
