First-Year College Students’ Conflict with Religion and Science

This study took place during a First Year Seminar course where 20 incoming college freshmen studied the central topic of the nature of science within the context of biological evolution. The instructor researched students’ understandings in the nature of science as they progressed through the course by examining a variety of qualitative and quantitative data including class writings, pre- and post-test selected items from the VOSTS (Views on Science-Technology-Society), and interviews. The intended outcomes of the course were to reduce the number of student misconceptions in the nature of science and to ease student apprehension when learning about evolution. Data were analyzed to determine whether students were moving toward a more generally accepted idea of the nature of science or toward another type of misconception.     

Classroom

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science. This project was done as part of the Research Education Advancement Programme held over weekends at the Bangalore Association for Science Education, Jawaharlal Nehru Planetarium, Bangalore.     

Effects of organizational pictures and modality as a feedback strategy on learner comprehension and satisfaction

One of the strongest instructional interventions documented in educational literature is the use of feedback to influence learning outcomes. However, there is lack of empirical research specifically pertaining to the use of multimedia in the feedback message. The purpose of this research was to test whether organizational pictures and modality as a feedback strategy had an effect on learner comprehension and satisfaction. The research design was a 2 Multimedia (Picture Present vs. Picture Absent) × 2 Modality (Narration vs. On-screen Text) × Trial (Trial 1 vs. Trial 2) with Multimedia and Modality serving as between-subject conditions and Trial serving as a repeated measure. One-hundred fifteen university students participated in the study. Findings show statistically significant increases in comprehension scores from Trial 1 to Trial 2 assessments for all four treatment conditions. Learners in the Picture present conditions were statistically more satisfied with the learning experience. Additionally, we used eye-tracking to verify the extent to which the pictures were used in the feedback message. A discussion and recommendations for future research and feedback design are provided.     

Tea polyphenols dominate the short-term tea (<Emphasis Type="Italic">Camellia sinensis</Emphasis>) leaf litter decomposition

Polyphenols are one of the most important secondary metabolites, and affect the decomposition of litter and soil organic matter. This study aims to monitor the mass loss rate of tea leaf litter and nutrient release pattern, and investigate the role of tea polyphenols played in this process. High-performance liquid chromatography (HPLC) and classical litter bag method were used to simulate the decomposition process of tea leaf litter and track the changes occurring in major polyphenols over eight months. The release patterns of nitrogen, potassium, calcium, and magnesium were also determined. The decomposition pattern of tea leaf litter could be described by a two-phase decomposition model, and the polyphenol/N ratio effectively regulated the degradation process. Most of the catechins decreased dramatically within two months; gallic acid (GA), catechin gallate (CG), and gallocatechin (GC) were faintly detected, while others were outside the detection limits by the end of the experiment. These results demonstrated that tea polyphenols transformed quickly and catechins had an effect on the individual conversion rate. The nutrient release pattern was different from other plants which might be due to the existence of tea polyphenols.     

Development and Evaluation of Turkish Language Versions of three Positive Psychology Assessments

This study reports the development and evaluation of a Turkish-language version of three positive psychology assessments for use in clinical, education and research settings with Turkish-speaking individuals. A multistage translation of the Brief Resilience Scale (BRS; Smith et al. in International Journal of Behavioral Medicine, 15, 194–200, 2008), the General Mattering Scale (GMS; Marcus 1991) and the Short Grit Scale (GS; Duckworth & Quinn in Journal of Personality Assessment, 91, 166–174. doi:10.1080/00223890802634290, 2009) is detailed, as well as the procedure used to evaluate the internal structure of the translated assessments. The results yielded from data of 268 participants indicated factor structures ranging from acceptable to robust model fit for the BRS, GMS, and GS. Implications for counseling practice and future research are discussed.     

Inclusive schooling policy: An educational detective story?

Since the publication of the Salamanca statement (UNESCO 1994), inclusive schooling has formed a growing part of the deliberations of the special education community. Inclusive schooling research in Australia in the main continues to reproduce traditions of the special education field, emphasising the dominant psychological perspectives that have been superimposed on inclusive education discourses. At the fifth International Congress of Special Education (ISEC 2000) held in Manchester, ‘the death knell of the concept of special education’ (ISEC 2000) was announced. The concept proposed by Mike Oliver, Professor of Disability Studies at the University of Greenwich, asserts an end to understandings of diversity dependent on medical, psychological and charity-based discourses. From a recent study of inclusive schooling policy, and drawing from poststructuralist methodology, I suggest an approach to research, policy development and practice that questions traditionalist theorising in the special education field. Reflecting on the implementation of the Inclusion of Students with Disabilities Policy (DECCD 1995) in the Tasmanian government school system, I outline my alignment with Oliver’s view and highlight how questions of epistemology and reconstructions of research methodologies are central to rethinking understandings of difference. I also illustrate a methodological orientation that offers possibilities for a different science to take place, thereby understanding diversity as multiple and contradictory — and beyond the single ‘detective story’ (Gough 1998) of the medical, psychological and charity-based discourses that circulate in schools as the populist conceptions of ‘inclusion’.     

Academic language and the quality of written arguments and explanations of Chilean 8th graders

Writing is a task that entails high cognitive and linguistic efforts, especially when producing academic texts. Academic language might be one of the factors influencing the quality of written texts, given that prior research has shown its impact on reading comprehension. The purpose of this study is to examine the contribution of Spanish Core Academic Language Skills (S-CALS) and academic vocabulary to the quality of written argumentation and explanation. For this study, 126 Chilean 8th grade students produced an argumentative text and an explanatory text about the same topic. In addition, their academic vocabulary was assessed with the S-AVoc-T test and their CALS with the S-CALS-I test. Results show that both CALS and academic vocabulary are significantly and positively correlated with both writing tasks. Even though these instruments make different contributions to the predictive models in each discursive genre, a Principal Component Analysis revealed that the model that best explains writing quality are those which combine both language variables, namely Spanish Core Academic Language and Vocabulary Skills (S-CALVS). In argumentation, the S-CALVS model explains 29% of the variance, after controlling by gender. In contrast, in explanation, S-CALVS explains 35% of the variance. It is concluded that it is relevant to develop situated writing in each discursive genre and, upon that basis, to work with both CALS and academic vocabulary, because they have a specific impact on academic texts writing.
