Associations of epistemic beliefs in science and scientific reasoning in university students from Taiwan and India     

Fang-Ying Yang  Kaushal Kumar Bhagat  Chia-Hui Cheng 《International Journal of Science Education》2019,41(10):1347-1365

The purpose of this study was to compare the associations of epistemic beliefs in science, performance of scientific reasoning in university students from Taiwan and India, and the relations with their science learning experiences. A total of 126 university students including 67 from Taiwan and 59 from India who had science and mathematics backgrounds were involved in the study. Students’ epistemic beliefs in science were assessed by the SEV questionnaire, while their reasoning performance and learning experiences were prompted by open-ended questions and survey items. Content analysis was performed to analyze their scientific reasoning, and correlation analysis, t tests and ANOVA were applied to reveal the associations between variables. The results showed that students from both countries differed in epistemic beliefs in the dimensions of certainty, development and justification. While few students from either country performed successfully in identifying genuine evidence and giving full rebuttals, Taiwanese participants seemed to demonstrate slightly better scientific reasoning. It was found that the Indian students were more balanced in receiving structured and engaged learning experiences. Varying associations for the students from the different countries were found between epistemic beliefs and scientific reasoning performance, and between epistemic beliefs and science learning experiences.  相似文献

Mathematics in ancient India     

Amartya Kumar Dutta 《Resonance》2004,9(1):61-63

Inadvertently, an earlier draft of this article got printed in the November 2003 issue and, since the new draft clarified some of the points, the section ‘Brahmagupta’s lemma and modern algebra’ of the final draft and a few small remarks are being reprinted for the reader’s convenience. The error is regretted.  相似文献

Āryabhata and axial rotation of Earth     

Amartya Kumar Dutta 《Resonance》2006,11(3):51-68

Āryabhata (born 476 CE) is regarded as a pioneer of mathematical astronomy in ancient India. In this three-part article, I shall discuss one important contribution of Āryabhata in astronomy involving the least technical background —the principle of axial rotation (Part 1) and computations on the sidereal day (Part 2). Portions of 4 verses, pertaining to Earth’s rotation, from his famous treatise Āryabhatīya will be quoted. In Part 3, I shall give a brief historical account on the concept of axial rotation of Earth.  相似文献   

Mathematics in ancient India     

Amartya Kumar Dutta 《Resonance》2002,7(4):4-19

In this series of articles, we intend to have a glimpse of some of the landmarks in ancient Indian mathematics with special emphasis on number theory. This issue features a brief overview of some of the high peaks of mathematics in ancient India. In the next part we shall describe Aryabhata’s general solution in integers of the equationax -by =c. In subsequent instalments we shall discuss in some detail two of the major contributions by Indians in number theory. The climax of the Indian achievements in algebra and number theory was their development of the ingeniouschakravala method for solving, in integers, the equation x² -Dy² = 1, erroneously known as the Pell equation. We shall later describe the partial solution of Brahmagupta and then the complete solution due to Jayadeva and Bhaskaracharya.  相似文献   

Trends in computer applications in science assessment     

David D. Kumar  Stanley L. Helgeson 《Journal of Science Education and Technology》1995,4(1):29-36

Seven computer applications to science assessment are reviewed. Conventional test administration includes record keeping, grading, and managing test banks. Multiple-choice testing involves forced selection of an answer from a menu, whereas constructed-response testing involves options for students to present their answers within a set standard deviation. Adaptive testing attempts to individualize the test to minimize the number of items and time needed to assess a student's knowledge. Figurai response testing assesses science proficiency in pictorial or graphic mode and requires the student to construct a mental image rather than selecting a response from a multiple choice menu. Simulations have been found useful for performance assessment on a large-scale basis in part because they make it possible to independently specify different aspects of a real experiment. An emerging approach to performance assessment is solution pathway analysis, which permits the analysis of the steps a student takes in solving a problem. Virtually all computer-based testing systems improve the quality and efficiency of record keeping and data analysis.  相似文献
