Rhetoric of Science: Enriching the Discipline

The author discusses how pursuing a rhetoric of science has consequences for both our understanding of science and our practice of rhetorical analysis. From a rhetorical perspective, science becomes a persuasive enterprise continuous with other persuasive practices in a culture. And rhetoric itself requires enrichment in three areas to become a better instrument of analysis for scientific texts; it needs to incorporate early modern dialectic, a more flexible stylistics, and an appreciation of the role of visualization in scientific argument.

The multiple sources of workplace stress among land-grant university faculty

Workplace stress has received a fair amount of treatment in the research literature over the past decade. What has not been examined, at least not systematically, is this same phenomena inacademe. Our study looked at stress among university faculty at a land-grant university located in the western region of the U. S. Analyses from the self-assessment mail survey (N = 786) reveals that faculty in the Hard Pure Nonlife (e. g., Astronomy, Math, Physics), Hard Applied Nonlife (e. g., Civil Engineering, Nuclear Engineering, Computer Science) and Soft Applied Life (e. g., Education Administration, Special Education) experience more stress than faculty in disciplines such as Hard Pure Life (e. g., Botany, Zoology) and Soft Pure Nonlife (e. g., English, Philosophy, Communications). Careful attention was paid to the different levels of stress reported by male and female faculty, with women professors reporting a higher level of stress than their male counterparts. We provide an assessment and explanation for this finding. Research ends with several proposals for individual faculty, department chairs and academic administrators for addressing the problem of workplace pressure and work overload.     

A flow-map method of representing cognitive structure based on respondents' narrative using science content

Increasing interest in science education research has focused on ways of representing cognitive structure in graphical and quantitative terms. A method is presented for displaying the sequential and multirelational ideation of scientific narrative elicited from respondents. The flow map provides a figural representation of the flow of information, the points in the flow where multirelational and recurrent linkages are made, and the time required to retrieve and express the information at major intervals in the sequence and in total. In keeping with constructivist models of information analysis, the elicitation of responses requires minimal intervention by the interviewer, and flow-map representation requires low inference for its construction, providing a convenient diagram of the sequential and multirelational thought patterns expressed by the respondent. The method is illustrated by analyzing interviews from students varying in academic achievement under two interview conditions that varied in emphasis on recall of multiple relationships. The illustrative data show that students of increasing academic ability produce flow maps of more complex patterns with more cross-relational linkages. These kinds of linkages, on the whole, increase with increased emphasis in the interview on recall of relationships.     

Teaching strategies associated with conceptual change learning in Science

The use of teaching strategies associated with a conceptual change model of science teaching was examined in a study of thirteen 7th-grade life science teachers. Teachers taught units on photosynthesis, cellular respiration, and matter cycling in ecosystems in their regular classes under conditions varying as to whether or not conceptual change-oriented instructional materials and training sessions were provided. Greater use of conceptual change teaching strategies was associated with use of the special instructional materials, but not with the training. Students in classes where teachers were provided with the materials tended to perform better on posttests than those where such materials were not provided. The use of the conceptual change strategies by teachers was also associated with higher student performance on tests designed to assess conceptual change learning. The results support claims for the usefulness of conceptual change teaching strategies, but few of the teachers in this study could successfully implement these strategies without the support of appropriately designed curriculum materials.     

Challenging teacher beliefs about student engagement in mathematics

This study explored the beliefs about student engagement in mathematics of three Year 5 and 6 teachers, focusing on the shifts that occurred during a 10-week intervention. Data obtained from teacher surveys, interviews, video-recorded workshop observations and artefacts from teachers’ classrooms reveal variations in their reactions to the professional learning experiences. Teacher responses were mediated by personal and contextual elements including teacher efficacy beliefs, teacher confidence in mathematics and their conceptions of student engagement. Theories of teacher conceptual change are used to account for variations to teacher beliefs.     

Moving beyond academic achievement goal measures: A study of social achievement goals

The current research explored the theory of social goal orientation. More specifically, we conducted three studies utilizing six-independent university student samples to evaluate the construct validity of the Social Achievement Goal Orientation Scale (SAGOS; Ryan & Hopkins, 2003), a measure representing the construct of social goal orientation. The purpose of Study 1 was to: (1) compare the three-dimensional (mastery, performance-approach, and performance-avoidance) model of social goal orientation to three theoretically based competing models, (2) examine item functioning, and (3) assess generalizability of the factor structure. The fit of the proposed three-factor model was promising; however, areas of misfit and problematic items were identified. Stronger support for the three-factor structure of goal orientation was found using scores from an abbreviated 13-item SAGOS. In Study 2, item wording was altered slightly to evaluate a revised Social Achievement Goal Scale (SAGS), yet resulted in similar findings. Study 3 examined external validity evidence for the SAGS, garnering some support for the meaning of the scores. Although continued refinement of the SAGOS and SAGS is recommended, the findings help contribute to our general understanding and conceptualization of social goal theory and the role that social goals may play in academic contexts.
