Abstract

This research is a preliminary study that focuses on multi-representation analysis of the chemical bonding topic in three general chemistry of text books. The analysis was carried out to find out how concepts are explained based on the three levels of chemical representation, especially on ionic and covalent bonding, which are the basis for further research in developing intertextual-based learning strategies. Analysis was carried out at the macroscopic-symbolic and sub microscopic-symbolic levels usingmulti-representation analysis table that was adopted from Gkitzia et al., 201 for three general chemistry books, that are 1) Whitten, K.W, et.al. (2014).  Chemistry 10th edition. English: Brooks/Cole Cengage Learning; 2) Chang, R. (2010). Chemistry 10th edition. New York : The McGraw-Hill Companies; and 3) Silberberg, M.S, and Amateis, P.G. (2021). Chemistry: the molecular nature of matter and change 9th edition.  New York : The McGraw-Hill Companies. The analysis results show that book: Silberberg, M.S, and Amateis, P.G. (2021). Chemistry: the molecular nature of matter and change 9th edition.  New York : The McGraw-Hill Companies has the most complete macroscopic-symbolic and sub microscopic-symbolic representation levels on the four main concept labels of chemical bonding, so that they can become standard reference material in developing chemical representations that will be used in intertextual learning strategies.

Abstract

3D printing transforms abstract contexts into more concrete ones and effectively enhances creativity. The purpose of this study is to explore the benefits and challenges teachers face in using 3D printing. The research method used in this study involved a narrative review of various literatures related to the use of 3D printing by science teachers. The results of this study show that there are benefits in using 3D printing as well as barriers experienced by science teachers. The benefits obtained by teachers are not only limited to themselves but also colleagues due to collaboration and of course for students. Teachers' pedagogical skills in designing lessons and using technology also experienced positive changes. Meanwhile, the obstacles in using 3D printing are also felt by teachers such as limited teacher skills, availability of tools and the use of tools that are relatively time-consuming.
