“…Tetapi pemahaman yang tidak holistik tentang perubahan kimia berdampak kepada pemahaman konsep selanjutnya, seperti gagal memahami peran ikatan dan energi pada reaksi kimia [4], dan jenis reaksi [5]. Siswa juga mengalami hambatan menyetarakan, | 28 memprediksi produk, dan menterjemahkan dari narasi ke persamaan reaksi [6].…”

The purpose of this study is to identify first year university students' understanding of the concepts of physical and chemical changes. This study involved 43 students from the 2019 batch of the Chemical Education Study Program (PSPK) of the Faculty of Science and Education (FKIP) of the Syiah Kuala University (USK) which was dominated by women (only 2 men). According to the objectives, the study used a survey method and used an instrument in the form of a questionnaire containing 15 statements. Participants were asked to provide responses via google form by choosing true or false for each statement item on the questionnaire. The results of the analysis show that the understanding of the majority of students is quite good for macroscopic markers or indicators and low for sub-microscopic markers or indicators. Therefore, chemistry teachers need to use molecular (sub-microscopic) images when teaching materials or topics of physical and chemical changes.

“…Studies of [1,2] argued that success in studying Chemistry depends upon the familiarity of students with a few basic ideas, conventions, and methods upon which later studies are built. When a student has achieved mastery of them, further studies can be pursued with greater confidence.…”

“…The 2004 chemistry theory paper required candidates to write a balanced chemical equation for the production of oxygen when KClO is heated and then calculate the volume of the dry oxygen gas evolved [20]. The examiners' CE report for the above question noted that candidates had problems writing the equation correctly and hence could not get the correct mole ratio [21].…”

The researchers interested to assess and improve the general understanding of Generalist Focus Year II students in Nekemte College of Teacher education on chemical symbols, chemical formulae and chemical equations which are the fundamental elements of chemistry for anyone to begin learning this subject. Methods:The study was both qualitative and quantitative type of research, because both numerical and non-numerical data were collected during the study through questionnaire, classroom observation, pre-and post-attitude tests and written tests. As type and source of data, the study used only primary. We used all the population as samples (totally 98 students in both sections) purposely. For the implementation of the action research, we first prepared action plan, applied the interventions, analyzed the changes and reported the results.Results: Based on our null hypothesis, from both attitude tests (questionnaire) and written tests (for both pre-and post-) there is progressive change observed after interventions. From the base line data questionnaire of 15 items, almost 79.5 % of the respondents disagreed for items 1-11 (except item 5) which are assessing the students background on chemical symbols, chemical formulae and chemical equations and very high interest was raised from the students on items 12-15 (highest agreement for both item 12 & 13 by 93.88 % response) which were asking students' interest to learn the basic elements of chemistry languages. After interventions, both post-tests showed correlatively progressive figure in addition to the observations conducted during all interventions. For the attitude test analysis almost, the reverse responses were recorded with agreement response (in average 71.93 %) and for the written test result analysis at p (0.05) the t-statistic is greater than t-critical in all the three cases i.e. chemical symbols, chemical formulae and chemical equations.
