College students’ attitudes towards sexually themed science content: a socioscientific issues approach to resolution

A socioscientific issues integrated instruction was used in the study to resolve college students attitude towards sexually-themed science content. Some 200 college students participated in the study as experimental and control groups. The former consisting of 98 students from one college was taught the content using the socioscientific issues integrated instruction. The later with 102 students from another college was taught the same content using a traditionally teacher dominated lectures. Both groups were taught over a period of eight weeks. Qualitative and quantitative data were obtained before and after the intervention. The quantitative data were analysed using analysis of covariance. The results revealed that there was a significant difference between the experimental and the control groups (F (1, 247) = 426.97, p = .00, partial eta squared = 0.64) where the experimental group showed a significant change in attitude towards the content studied. The qualitative data obtained some experimental group students showed a change in attitude the second interview. It was concluded that the use of the approach has significantly made the college students feel comfortable and confident to learn and teach the content.     

Zooming in on infinitesimal 1–.9.. in a post-triumvirate era

The view of infinity as a metaphor, a basic premise of modern cognitive theory of embodied knowledge, suggests in particular that there may be alternative ways in which one could formalize mathematical ideas about infinity. We discuss the key ideas about infinitesimals via a proceptual analysis of the meaning of the ellipsis “...” in the real formula \(\hbox{.999\ldots = 1}\). Infinitesimal-enriched number systems accommodate quantities in the half-open interval [0,1) whose extended decimal expansion starts with an unlimited number of repeated digits 9. Do such quantities pose a challenge to the unital evaluation of the symbol “.999...”? We present some non-standard thoughts on the ambiguity of the ellipsis in the context of the cognitive concept of generic limit of B. Cornu and D. Tall. We analyze the vigorous debates among mathematicians concerning the idea of infinitesimals.     

The Effects of Socio-scientific Instruction on Pre-Service Teachers’ Sense of Efficacy for Learning and Teaching Controversial Family Health Issues

This research investigates the effects of socioscientific instruction on pre-service teachers’ sense of efficacy in the teaching and learning of controversial family health issues. For this purpose, a total of 251 students from two teacher training colleges participated in the study and were randomly assigned as experimental and control groups. The experimental group was taught the contents of the controversial family health issues using socioscientific instruction approach and the control group was taught the same content using a more traditional approach. Quantitative data were obtained from both groups after responding to the ‘Teacher sense of Efficacy Scale’ as instrument used for data collection before and after the treatments. Analysis of covariance was used in data analysis of which the pre-treatment scores were used as covariates. Qualitative interviews were conducted with ten participants randomly selected from the experimental group before and after the treatment to deepen and elaborate the quantitative data. The quantitative and qualitative findings indicate that the integration of the socioscientific instruction have significantly affected the pre-service teachers’ sense of efficacy in favour of the experimental group that shows a more stronger sense of efficacy. It was concluded that the socioscientific instruction is significantly effective in changing the pre-service teachers’ weaker sense of efficacy to a stronger one in the controversial family health issues.

Cultural transitioning of Jewish immigrants: Education, employment and integration

This paper discusses the cultural transitioning process that immigrants undergo in order to attain educational, occupational, and social integration within Canadian society. Results of this phenomenological study examining 31 Jewish immigrants from Argentina, Israel, France and the Former Soviet Union, reveal that lack of educational equivalency and lack of recognition of foreign work experience, language barriers, discrimination, insider/outsider sentiments and the structure of the community were common impediments to cultural transitioning. However, findings suggest that despite a common religious identity, immigrants’ ethnic identities and expectations lead to divergent cultural transitioning experiences.     

Community College Students' Conceptual Understanding of Statistical Measures of Spread

This study investigated the conceptual understanding of measures of spread among community college students in an introductory statistics course. The course is centered around deemphasizing computational skills and focused, rather, on development of conceptual understanding. Open-ended questions were developed to explore and assess students' conceptual understanding of measures of spread. A detailed analysis of the students' responses is presented to reveal the range of students' conceptions of the measures of spread. The analysis of a wide variety of responses provides evidence of the students' ability to organize concepts of spread in a way that is meaningful to them individually. Some common student misconceptions revealed by this study should be examined closely and taken into consideration to promote students' development of understanding of spread.     

Organizational evolution and the Olympic Games: the case of sport climbing

Abstract

This paper discusses the processes underpinning the evolutionary development of sport climbing in recent decades, with a particular focus on the impact of its inclusion in the Olympic Games. New institutionalism and resource-dependence theory provide an analytical and explanatory framework for this study. The research adopted a qualitative method strategy comprising a series of interviews and the analysis of documents, reports, press and social media. The recent inclusion of the sport in the Tokyo 2020 Olympic programme has created challenges, primarily because of strong values inherent within the sport. The research, however, shows that the values of a sport can expand and develop in order to fit the regulatory legitimacy required by inclusion in the Olympic Games. Nonetheless, the research also shows that involvement with the IOC raises questions about who ‘owns’ the sport.
