A comprehensive history of Astronomy should show in reasonable chronological order, the contributions from wherever they arise in the world, once they are reliably documented. However, the authors note that consistently, the extremely rich contributions from Ancient Indian scholars like Aryabatha and Bhramagupta are omitted in Eurocentric education and syllabi. It is speculated whether religious underpinnings could have been responsible for its suppression in the past. An appeal is made to represent the history of Astronomy in Eurocentric versions, to be inclusive of Indian Astronomy as accurately and completely as possible in science education. 相似文献

ABSTRACTThis paper presents results from a small-scale study of third-year Instrumentation and Control Engineering (n?=?37) at the University of Plymouth. The aim of the study was to enhance student learning and increase participation via the use of clickers. Clickers allow for student participation anonymously. The lecture content was modified to embed clicker questions at regular intervals to test knowledge, understanding and cognitive skills. Largely, the students preferred interactive lectures to traditional didactic lectures and using clickers increased student engagement and participation. Interestingly, compared to assessment results from the previous year, the increased level of engagement did seem to lead to an overall improvement in grades of approximately 10% in the subject of Control Engineering. However, in Instrumentation, the average fell by approximately 20%. One possible contributory factor of this drop could be the changed exam format for Instrumentation only. This year, the multiple choice section was removed from the Instrumentation examination paper. Furthermore, an analysis of variance showed that in addition to using clickers in the lectures, attendance plays a key role. Results of this small-scale study show that for a more complex subject like Control, student learning, engagement and attainment can increase by the use of clickers. 相似文献

The law of mass-action led chemists to the belief that reactions approach equilibrium steadily. So the discovery of chemical
oscillations came as a surprise. Now chemists are very familiar with reactions that oscillate in time and/or space. Experimental
and theoretical studies of such reactions showing temporal and spatial oscillations attract the interest of many laboratories
world-wide. The Lotka-Volterra model is the simplest mathematical model which exhibits such oscillations. In this article,
we use this model to illustrate chemical oscillations with the help of a computer program. 相似文献

ABSTRACTThe aim of this study is to determine primary school administrators’ and teachers’ opinions about the quality of their schools; the school administrators and teachers’ knowledge about Total Quality Management and quality tools and the quality tools used in primary schools. The research has been carried out with a qualitative approach and it is in the case study pattern. The participants consisted of 16 teachers and 4 school administrators working in primary schools in North Cyprus. The participants were chosen via maximum sampling method. The findings show that the current situation in schools contradicts with the basic principles of Total Quality Management. It was determined that school administrators were ignorant about Total Quality Management and none of the teachers and school administrators had previously heard the concept of quality tools. Teachers and school administrators mentioned disabled students as an issue. It seems like teachers have problems in behaving in the right way towards these students. They do not know how to improve these students’ talents because they are not educated on the subject. Via tools of quality teachers and school administrators may find reasons and solutions for issues like people with disabilities and plan events to promote disability awareness. 相似文献

We report on an investigation of students' ideas about gravity after a semester of instruction in physics at university. There are two aspects to the study which was concerned with students' answers to a carefully designed qualitative examination question on gravity. The first aspect is a classification of the answers and a comparative study of the ways the problem was tackled by two large groups of students who had different backgrounds in physics and were exposed to different teaching styles. The second aspect is to investigate how students link concepts to solve the problem. We used a phenomenographic analysis of student responses to extract patterns of reasoning and alternative conceptions behind the solutions. We found no differences between the classes of answers given by students in the two courses. Our analysis also identifies a hierarchy in the complexity of the hypothetical reasoning pathways, which we interpret as reflecting the ways in which students may link concepts and resolve conflicts as they solve the problem. The hypothetical reasoning pathways may help educators to develop instructional material or lecture room dialogue in order to tease out key issues. An unexpected finding is that there is a discrepancy between our conclusion that the two groups of answers are similar and the distribution of marks awarded by the examiner – which implies that the quality of the answers is different for the two groups. 相似文献

Since their inception in 1993 at an Australian university, the workshop tutorials in physics have evolved and grown beyond the initiating department. In this paper, we adopt an interpretive perspective to: (i) reflect on why the tutorials continue to be successful; (ii) use models from literature to understand that success; and (iii) abstract key features that can inform scholarly inquiry into teaching and learning in higher education in other contexts and discipline areas. Practitioner (action) research and design‐based research not only provide useful methodological frameworks that support the success of the workshop tutorials, but they also offer a worthwhile methodological strategy for fostering scholarly inquiry into university teaching and student learning. 相似文献

This article is about the moving toward a new instruction style—a transformative model of instruction. One university instructor attempts to change her teaching strategies, and she encounters her own belief as obstacles, self-labeled her pedagogical discrepancies. Through peer feedback, reflective journal writing, and readings she uncovers the obstacles and discovers how the beliefs need to change in order to implement transformative teaching strategies. The change is incorporated into five lessons: it is easier to tell than to listen; modeling needs to go beyond a monologue; be humble and learn from the students; there are more ways to the same end; and, grading the end product or acknowledging the risk. Her lessons take on a spiral nature of learning, and incorporate detailed emotional–psychological resistance. In doing so, she gains a deeper understanding of her instruction, and becomes better equipped to prepare other reflective practitioners. The study takes place in the continental United States of America. 相似文献

An economical and less time consuming microtitration method is presented. The method has been applied to two types of titration,
viz., neutralization and complexometric. The results obtained by the new method are comparable to those obtained by conventional
method using burette and pipette. It is proposed that this method can be implemented in high school and undergraduate classes
as the quantities of chemicals consumed are far less and the experiment can be completed within the given laboratory period. 相似文献
