The Use of Ethical Dilemma in Mathematics Lesson to Cultivate Students’ Ethical Awareness 利用数学课堂中的伦理困境培养学生的伦理意识
M. Simanjorang, Pardomuan N. J. M. Sinambela, B. Sinaga
Indonesian educational community has been focusing on character education recently. Character is usually cultivated upon a set of assumed values that is embraced in one’s social environment. This set of values closely related to awareness of ethical values and social relational system in society. Ethical consideration emerges upon the existence of others. The question is if we need to cultivate ethical awareness and consideration then how can we approach this ethical consideration in mathematics education. The researchers team believe that there are valuesin mathematics itself moreover in mathematics education. With this kind of assumption the researchers team are called to find a way to cultivate students’ ethical awareness through learning activities. According to some research one possible way for this purpose is the use of ethical dilemma problems. Dilemma occurred in a proposed problem will push a person to consider ethical values before making a decision. Hence, this article aims to describe the possibility of using such ethical dilemma problem in mathematics lecture to cultivate students’ ethical awareness. The research described in this article using critical interpretivism paradigm and represented in a narrative inquiry method.
最近,印尼教育界非常重视品格教育。性格通常是建立在一套假定的价值观上的,这些价值观是在一个人的社会环境中被接受的。这套价值观与社会的伦理价值意识和社会关系制度密切相关。伦理考虑是基于他人的存在而产生的。问题是,如果我们需要培养伦理意识和思考,那么我们如何在数学教育中接近这种伦理思考。研究小组认为,数学本身有价值,数学教育也有价值。在这种假设下,研究团队需要寻找一种通过学习活动来培养学生伦理意识的方法。根据一些研究,达到这一目的的一种可能的方法是使用道德困境问题。在提出问题时出现的困境会促使一个人在做决定之前考虑道德价值。因此,本文旨在描述在数学课堂中运用这种伦理困境问题来培养学生伦理意识的可能性。本文所描述的研究采用批判解释主义范式,并以叙事探究法为代表。

Research has been conducted on the antibacterial activity analysis of Zanthoxylum acanthopodium DC extract on Bacillus subtilis, Salmonella typhi using disc diffusion method. This study aims to determine the ability of Zanthoxylum acanthopodium DC extract in inhibiting the growth of Bacillus subtillis, and Salmonella typhi. Zanthoxylum acanthopodium DC was extracted by maceration method using 96% ethanol. In this extraction process, phytochemical test was carried out to find out the secondary metabolite content in Zanthoxylum acanthopodium DC. Phytochemical test indicate Zanthoxylum acanthopodium DC contained alkaloids, tannins, saponins, and steroids. Antibacterial activity analysis were measured in three concentrations of 25%, 50%, 75%. The best antibacterial activity was observed on Salmonella typhi bacteria with 75% extract concentration which produced a clear zone diameter of 19 mm and 20 mm.

As result: 1) the increasement of students’ achievement which taught by using inquiry-based model is higher than the conventional model with t-table (1.666) > tstatistics (3.700) for cognitive domain, t-statistics (4.208) for affective domain, and tstatistics (4.798) for psychomotor domain, 2) the increasement of students’ science process skill which taught by using guided inquiry-based model is higher than conventional model with t-statistics (4.376) > t-table (1.6663), 3) there is significant correlation between students’ achievement with science process skill by implementing guided inquiry-based model with very high criterion respectively 0.900, 0.860, and 0.819 for cognitive, affective and psychomotor domain.","PeriodicalId":240056,"journal":{"name":"Proceedings of the Proceedings of The 5th Annual International Seminar on Trends in Science and Science Education, AISTSSE 2018, 18-19 October 2018, Medan, Indonesia","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131772417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
