Setting examination questions in real‐world contexts is widespread. However, when students are reading contextualized questions there is a risk that the cognitive processes provoked by the context can interfere with their understanding of the concepts in the question. Validity may then be compromised. We introduce the concept of focus: a question in a given context is focused to the extent that it addresses the aspects of the context that will be most salient in real life for the students being tested. A more focused context will then help activate relevant concepts, rather than interfering with comprehension and reasoning. In this study, the contexts of questions from a science test for 14‐year‐olds in England were manipulated to increase or decrease the amount of focus. In every instance more focused questions proved better than less focused ones. With additional evidence from interview protocols, we also consider the effects of context focus on the question answering process. 相似文献

Syzygium campanulatum Korth is a plant, which is a rich source of secondary metabolites (especially flavanones, chalcone, and triterpenoids). In our present study, three conventional solvent extraction (CSE) techniques and supercritical fluid extraction (SFE) techniques were performed to achieve a maximum recovery of two flavanones, chalcone, and two triterpenoids from S. campanulatum leaves. Furthermore, a Box-Behnken design was constructed for the SFE technique using pressure, temperature, and particle size as independent variables, and yields of crude extract, individual and total secondary metabolites as the dependent variables. In the CSE procedure, twenty extracts were produced using ten different solvents and three techniques (maceration, soxhletion, and reflux). An enriched extract of five secondary metabolites was collected using n-hexane:methanol (1:1) soxhletion. Using food-grade ethanol as a modifier, the SFE methods produced a higher recovery (25.5%?84.9%) of selected secondary metabolites as compared to the CSE techniques (0.92%?66.00%). 相似文献

Attitudes of special education teachers towards using technology in inclusive classrooms: a mixed‐methods study 下载免费PDF全文
The purpose of this mixed‐methods study was to explore special education teachers’ attitudes towards using technology in inclusive classrooms in Oman. The sample consisted of 428 special education teachers working in Omani public schools (250 teachers of students with learning disabilities (LD), 90 teachers of students with intellectual disability and 88 teachers of students with hearing impairment). Participants responded to the attitudes towards computers questionnaire. For the qualitative section of this study, three semi‐structured group interviews were conducted with a group of special education teachers: 15 teachers of students with hearing impairment, 15 teachers of students with intellectual disabilities and 15 teachers of students with LD). Also, the teachers responded to a survey of educational technology which encompassed seven questions about computer technology. Results of the study indicated that the special education teachers’ attitudes towards using computers were generally positive. The most notable positive attitudes were in the following subscales: special education considerations, staff development considerations, computers use in society, and computers and quality of instruction issues. The analysis of variance results showed that experience and type of disability did not have a significant effect on teachers’ attitudes towards technology. 相似文献

The present study examined the reciprocal relationships between self-concept and anxiety in mathematics. A sample of 495 grade 7 students (51% girls) completed self-report measures assessing self-concept and anxiety three times in a school year. Structural equation modeling was used to test a cross-lagged panel model of reciprocal effects between math self-concept and math anxiety. The analysis showed a reciprocal relationship between self-concept and anxiety in math (i.e., higher self-concept leads to lower anxiety, which in turn, leads to higher self-concept). However, the magnitude of the path from anxiety to self-concept is almost half of that from self-concept to anxiety. Overall, the results provide empirical support for the theoretical notion that math self-concept and math anxiety are reciprocally related. 相似文献

In this paper, the author's first and foremost objective is to render the answer to the following question: Why is spirituality marginalized in the academy? The author searches for the answer to this question in the terrain of knowledge production and worldviews that permeate the Western academy. The author examines the landscape of the neo‐colonial academy and delineates the conditions that restrict the spaces for spirituality. The author's second objective is to explore possible answers to the following question: How would centering spirituality transform our ways of knowing? The author attempts to answer this question by providing some preliminary ideas on the question of epistemology, methodology and methods in a spiritually based inquiry. The author concludes that this journey is endless and this paper is just a stepping stone to the discussion revolving around the integration and centering of spirituality within the academy. 相似文献

Literature on Web 2.0 experiences of higher education faculty in developing countries such as Pakistan is very limited. An insight on awareness and practices of higher education faculty with these tools can be helpful to map strategies and plan of action for adopting latest technologies to support teaching–learning processes in higher education of such countries. This survey study was aimed to examine the competence and practices of higher education faculty in Pakistan with Web 2.0 technologies such as blogs, Wikis, Google Docs, Skype, Flickr, YouTube, and social networks. The study was also focused to look for what type of role faculty play while using these tools; and to find whether any significant differences in terms of age, gender, or academic discipline exist in competence and usage of these tools by the faculty. The data were collected from a sample of 246 university teachers in the spring 2014 semester. The findings of the study indicated that faculty participants reported to use Web 2.0 social tools more frequently than instrumental tools. Similarly, their competence with social tools was higher than their competence with instrumental tools. Additional results indicated that their competence with Web2.0 tools significantly differed with respect to their age, gender, and academic disciplines. 相似文献

ABSTRACTTeacher support for students in ubiquitous learning environments is challenging owing to physical distance and a lack of reliable real-time multimedia-rich communication. This is further complicated because the learning process is dynamic and problems need quick resolution. Given these challenges, this study proposes an architecture for a teacher facilitation support system. The system was implemented in the form of an interactive teacher dashboard. The interface also generates possible solutions to learning challenges while leaving the ultimate decision up to the teacher. The system feasibility was tested by work-through scenarios designed and validated by two experts. The system usability was evaluated using the System Usability Scale by 40 potential users. The ?ndings revealed that the dashboard has good feasibility and usability for providing teachers relevant information about their students’ learning progress in ubiquitous learning environments. It also enabled opportunity for pedagogical intervention when needed. 相似文献
