Constructing scientific arguments is an important practice for students because it helps them to make sense of data using scientific knowledge and within the conceptual and experimental boundaries of an investigation. In this study, we used a text mining method called Latent Dirichlet Allocation (LDA) to identify underlying patterns in students written scientific arguments about a complex scientific phenomenon called Albedo Effect. We further examined how identified patterns compare to existing frameworks related to explaining evidence to support claims and attributing sources of uncertainty. LDA was applied to electronically stored arguments written by 2472 students and concerning how decreases in sea ice affect global temperatures. The results indicated that each content topic identified in the explanations by the LDA— “data only,” “reasoning only,” “data and reasoning combined,” “wrong reasoning types,” and “restatement of the claim”—could be interpreted using the claim–evidence–reasoning framework. Similarly, each topic identified in the students’ uncertainty attributions— “self-evaluations,” “personal sources related to knowledge and experience,” and “scientific sources related to reasoning and data”—could be interpreted using the taxonomy of uncertainty attribution. These results indicate that LDA can serve as a tool for content analysis that can discover semantic patterns in students’ scientific argumentation in particular science domains and facilitate teachers’ providing help to students.

The number of educators, administrators, and institutions that utilize social networking has increased dramatically. Many have adopted social networking in order to be up-to-date and connected with their students’ learning beyond the boundaries of the classroom. However, this increase in the use of social networking in academia presents many potential issues. In this paper, we address the growing prevalence of social networking in education and some of the issues. Next, we use social role theory to explore some pitfalls for educators using social networking. Finally, we suggest that foundational ethical principles from the field of psychology can provide a basis for developing guiding principles for use of social networking in education. 相似文献

In this study, six Latina students shared perceptions of their parental influence on their educational aspirations. CRT, LatCrit, and community cultural wealth provide the tripartite framework for analyzing issues of race, class, gender, language, culture, and immigration by examining their roles in society through counterstories. Learning in an after-school program about educational advancement, these participants navigated against deficit ideology. Messages of aspirational hope, navigational inspiration, Spanish language guidance, familial kinship, social networking, and resistant intelligence enabled these students to build a foundation of personal emancipation to disrupt the systemic sociopolitical and sociocultural nature of oppression. 相似文献

Using first-person accounts of classroom experiences, five professors examine the intersection of social foundations and borderland theory and their efforts to move students through resistance to understanding and affirmation of sociocultural diversity. The authors present this paper in two parts, the first providing examples of using a borderland approach within the classroom and the second providing illustrations moving these borderland strategies beyond the classroom. In each case, authors show the interwoven nature of pedagogy, identity, knowledge, and experience as they work to connect theory and practice. All of the institutions represented have majority white populations, and many do not reflect the diversity of the communities in which they are situated. The need for borderland practices in social foundations courses is urgent in these areas. These pedagogical reflections, although not meant to be recipes for success, provide examples of practices that can serve to meet the growing demands from schools and communities for culturally competent, socially aware teacher–leaders, and reaffirm the critical importance of social foundations in teacher education. 相似文献

The Occupational Therapy department at the University of the Witwatersrand in South Africa is responsible for ensuring students achieve psychomotor skill proficiency, as it is an essential component of health care practice. The aim of this study was to determine whether the introduction of opportunities to afford self-evaluation better prepared students for psychomotor skill performance during clinical fieldwork. A quantitative analytical longitudinal design was used with a sample of second-year BSc occupational therapy students from 2007–2010. Self-assessment opportunities were introduced to students in 2009, enabling the comparisons of students’ performance based on Fitts and Posner’s motor skills learning theory. The results indicated that the pre-intervention group demonstrated poor psychomotor skill ability compared to the intervention group, concluding that students require deliberate opportunities to practice self-evaluation skills in their early years of study. 相似文献
