The influence of gender,ethnicity and rurality upon perceptions of science

This paper reports an investigation into gender, ethnicity and rurality on Fijian students’ perceptions of science. A questionnaire was administered to a large sample of Form 5 classes. All students had completed a four year integrated "Basic Science" course in the junior secondary school and were continuing their studies in the upper secondary school. The responses were analysed to determine the significance of gender, ethnicity and rurality on the students’ perceptions of science, attitudes to science in the world and to science in the school curriculum. Specializations: gender issues and affective aspects of science and technology education. Specializations: Constructivism in science education, development education and gender issues.     

The correction of errors committed with high confidence

Most theories predict that when people indicate that they are highly confident they are producing their strongest responses. Hence, if such a high confidence response is in error it should be overwritten only with great difficulty. In contrast to this prediction, we have found that people easily correct erroneous responses to general information questions endorsed as correct with high-confidence, so long as the correct answer is given as feedback. Three potential explanations for this unexpected hypercorrection effect are summarized. The explanation that is tested here, in two experiments, is that after a person commits a high-confidence error the correct answer feedback, being surprising or unexpected, is given more attention than is accorded to the feedback to low-confidence errors. This enhanced attentional capture leads to better memory. In both experiments, a tone detection task was presented concurrently with the corrective feedback to assess the attentional capture of feedback stimuli. In both, tone detection was selectively impaired during the feedback to high confidence errors. It was also negatively related to final performance, indicating that the attention not devoted to the tone detection was effectively engaged by the corrective feedback. These data support the attentional explanation of the high-confidence hypercorrection effect.     

A Science for Citizenship Model: Assessing the Effects of Benefits,Risks, and Trust for Predicting Students’ Interest in and Understanding of Science-Related Content

This study showcases the Science for Citizenship Model (SCM) as a new instructional methodology for presenting, to secondary students, science-related technology content related to the use of science in society not taught in the science curriculum, and a new approach for assessing the intercorrelations among three independent variables (benefits, risks, and trust) to predict the dependent variable of triggered interest in learning science. Utilizing a 50-minute instructional presentation on nanotechnology for citizenship, data were collected from 301 Taiwanese high school students. Structural equation modeling (SEM) and paired-samples t-tests were used to analyze the fitness of data to SCM and the extent to which a 50-minute class presentation of nanotechnology for citizenship affected students’ awareness of benefits, risks, trust, and triggered interest in learning science. Results of SCM on pre-tests and post-tests revealed acceptable model fit to data and demonstrated that the strongest predictor of students’ triggered interest in nanotechnology was their trust in science. Paired-samples t-test results on students’ understanding of nanotechnology and their self-evaluated awareness of the benefits and risks of nanotechology, trust in scientists, and interest in learning science revealed low significant differences between pre-test and post-test. These results provide evidence that a short 50-minute presentation on an emerging science not normally addressed within traditional science curriculum had a significant yet limited impact on students’ learning of nanotechnology in the classroom. Finally, we suggest why the results of this study may be important to science education instruction and research for understanding how the integration into classroom science education of short presentations of cutting-edge science and emerging technologies in support of the science for citizenship enterprise might be accomplished through future investigations.     

Using video clubs to develop teachers’ thinking and practice in oral feedback and dialogic teaching

ABSTRACT

The authors report outcomes of an evaluation of a ‘video club’ intervention to improve the feedback and dialogic teaching practice of 91 teachers from 11 primary schools in England. Participating teachers worked collaboratively in a sequence of six video clubs over a six-month period. To understand teacher engagement they examine videos of video club meetings; online platform use metrics; surveys; selected videos of classroom practice; focus groups; and interviews. They evaluate change in teachers’ thinking and practice using survey results for participants compared to a comparison group of non-participating teachers at the intervention schools. The survey includes a new instrument for gathering evidence of teachers’ thinking and practice in feedback. The results suggested changes in thinking and practice for teachers who self-reported as engaging highly with the intervention. They conclude by discussing the potential of video technology within professional development and the challenges of researching changes in thinking and practice.     

Positive and negative aspects of relationship quality and unprotected sex among young women

The aim of this study was to examine both positive and negative aspects of relationship quality in relation to condom use. Sexually active young women aged 14–18 years (n = 111; 34% non-white) were recruited from community clinics and schools in the Midwest USA and provided data via an online survey. The number of unprotected sex acts in the past month with the most recent male partner was regressed on relationship quality with that partner, adjusting for demographics and other characteristics. Negative relationship quality was associated with a greater number of unprotected sex acts among women reporting a low level of positive relationship quality and among women taking hormonal/IUD contraception. Positive relationship quality was associated with unprotected sex among women who reported multiple partners in the past month. Both positive and negative aspects of relationship quality may confer risk for unprotected sex. This risk appears to be modified by patterns of contraceptive use and other sexual behaviours. Health professionals and sexual health educators may be more effective in promoting condom use if they ask questions about both positive and negative aspects of young people’s relationship quality and tailor their conversations based on the responses received.     

Salt,time, and metaphor: examining norms in scientific culture

As has been widely discussed, the National Research Council’s (NRC) current policy in United States education advocates supporting students toward acquiring skills to engage in scientific practices. NRC policy also suggests that supporting students in the practices of science may require different approaches than what is required for supporting student engagement with scientific content. Further, acquiring skills in scientific practices is not limited to gaining proficiency in utilizing tools that support scientific inquiry: students must also understand how to interpret information generated from such tools. These tools of scientific practices are embedded within scientific culture, which from Sewell’s perspective, is comprised of both practice and semiotic code (symbols and meanings). To become scientifically literate students must learn to utilize this code in practice. Author Germà Garcia-Belmonte identified one example of learning to utilize the semiotic code in scientific practice and considers challenges faced by undergraduate physics and engineering students within that context. Garcia-Belmonte observes students struggle to interpret symbols and meaning (the visual display generated) while engaging in practice (utilizing an oscilloscope) and posits that two, culturally bound, competing, linguistic metaphors of time may be the cause. Ultimately, however, the author does not explore beyond hypotheses. Although his theory may be correct, the paper serves as a reminder of the responsibility we have to students. As educators, it is useful and beneficial to make observations and develop theories surrounding why our students struggle. However, in addition to theorizing on why, for example, a particular scientific norm might present challenges for our students, we must remain mindful that challenges may not be uniform and may vary considerably according to students’ culture(s). Engaging with students and soliciting specific information regarding the challenges they face allows us, as educators, to both examine whether students’ reported challenges align or conflict with our own perceptions of those challenges, and subsequently devise and test methods toward supporting students in overcoming their challenges.     

MEASURING THE CONFIDENCE OF 8TH GRADE TAIWANESE STUDENTS’ KNOWLEDGE OF ACIDS AND BASES

The present study investigated whether gender differences were present on the confidence judgments made by 8th grade Taiwanese students on the accuracy of their responses to acid–base test items. A total of 147 (76 male, 71 female) students provided item-specific confidence judgments during a test of their knowledge of acids and bases. Using the correctness of the answer responses, a confidence rating score, an unweighted rating score, and a relative confidence rating score were calculated for each respondent. The correlations between the boys and girls for each score area showed girls as scoring higher than boys in their knowledge of acids and bases, were more confident in this knowledge, and more willing to express different levels of confidence among the test items.

The Regime of Self-Evaluation: Self-Conception for Teachers and Schools

Self-evaluation in inspection policy has become a global phenomenon. The idea is that it increases levels of teacher and school autonomy, wherein both schools and teachers have more ownership and responsibility over their work. In turn, such a process has allowed for greater accountability, which is then said to provide high quality education and, therefore, greater competitive advantage amongst knowledge-based economies. In both England and Ireland, self-evaluation has become a demanding procedure that is meant to complement external inspections of schools and teachers. In this article, I will argue that self-evaluation, whilst having the potential to become a worthwhile endeavour, does not live up to its name. In the first instance, the criteria used for self-evaluation are not internally generated but externally imposed. Thus, I would like to discuss the extent to which visions of ‘good’ or ‘bad’ education developed by inspecting bodies influence the way in which teachers and schools assess themselves. Furthermore, I will raise questions as to what appropriate criteria for teaching might look like. In doing so, I shall try to show that what is now current is a debased form of self-evaluation that is not only detrimental to the self-perception of teachers, but inadequate to what any coherent notion of the ‘self’ might be. In light of work by the philosopher Charles Taylor in particular, I will argue that the self is not something that can be examined in the way that is imagined in these inspection systems but is rather something dynamic and unfixed, constituted within a wider community of practice and, therefore, not amenable to evaluation in quite the way that is supposed.
