Preliminary Study: Development of Algodoo-based Newtonian Teaching Materials to Improve Student’s Conceptual Understanding with Peer Instruction Method 基于算法的牛顿教材开发与同伴教学法提高学生概念理解的初步研究
M. A. Rangkuti, W. Ritonga, Ida Wahyuni, Septian Prawijaya
Some of the worlds physics communities have observed that student learning outcomes in introductory physics courses are weak and ineffective. To overcome this, one of the efforts to complete it is the development of effective teaching materials. Excellent teaching materials will help students in solving problems in learning including deep conceptual understanding. Many misconceptions occur for students who have completed introductory physics courses. Whereas in the introductory physics courses there are many major branches of physics. Conceptual understanding is a part that cannot be missed in the whole of physics learning. Weak understanding of the concept will affect the completion of mathematical physics questions. Sometimes students can solve a physics problem that is mathematical but does not understand the concepts contained in it. One method of solving physical misconceptions in students is to use peer learning methods whose activities are arranged in instructional materials developed based on Algodoo. This method is expected to reduce the misconceptions that occur for students who take Introductory Physics courses during their first year of college.
一些世界物理团体已经观察到,学生在物理入门课程的学习成果是薄弱和无效的。为了克服这一点,完成它的努力之一是开发有效的教材。优秀的教材将帮助学生解决学习中的问题,包括深刻的概念理解。学过物理入门课程的学生会产生许多误解。而在物理入门课程中,有许多主要的物理分支。概念理解是整个物理学习中不可缺少的一部分。对概念理解的薄弱会影响数学物理题的完成。有时学生可以解决数学物理问题,但不理解其中包含的概念。解决学生物理误解的一种方法是使用同伴学习方法,其活动安排在基于Algodoo开发的教学材料中。这种方法有望减少学生在大学一年级学习物理导论课程时产生的误解。

P. Putra, D. Syah, Baginda Halim Simatupang
Differences in interests between owners and managers cause information submitted to financial statements to be incorrect. The interests of owners who want increased company performance and value cause managers to plan strategies, one of which is tax avoidance. Therefore, this study aims to determine the conflict of interest between managers and owners who are described through institutional ownership of tax avoidance practices. This research was conducted on manufacturing companies listed on the Indonesia and Singapore Stock Exchanges. The results of this study became the basis of tax avoidance practices that occurred in the two countries as an implication of agency theory.
所有者和管理者之间的利益差异导致提交给财务报表的信息不正确。希望提高公司业绩和价值的所有者的利益促使管理者规划战略,其中之一就是避税。因此,本研究旨在通过避税行为的机构所有权来确定管理者和所有者之间的利益冲突。这项研究是对在印度尼西亚和新加坡证券交易所上市的制造业公司进行的。这一研究结果作为代理理论的暗示,成为两国避税实践的基础。
