Contoh Jurnal Tentang Stoikiometri Pdf ABSTRACT The purpose of this study was to investigate the characteristics of the TDS (Diagnostic Stoichiometric Tests) developed in this study, to identify and describe the causes of misconceptions of stoichiometry and to examine the differences in the consequences of stoichiometric misconceptions on high school students based on the differences in sex, grade, and language used. This study involved 1096 high school students class 2 and grade 3 in the City of Palangkaraya, Banjarmasin, and Samarinda. Student stoichiometric misconceptions are expressed using TDS of multiple choice and interview. The characteristics of TDS developed were: (1) stoichiometry composed by three sub-concepts and consisting of 15 P3S, (2) 48-item length, (3) 90 minutes working time, (4) P3S level of subclasses average 1,30 – 1.90 (accepted), (5) KBP rate = 0.85 – 0.96 (appropriate), (6) KBS level; Stress 0,1 -0,15 and RSQ 0,92 – 0,93 (according to model), (7) TK index = 0,31 – 0,68 (ideal), (8) index DB = 0,27 – 0.63 (ideal), and (9) coefficient index a Cronbach 0.93 (good). The results of the concentration analysis identified 30 misconceptions of stoichiometry by students, ie, 13 misconceptions about the equations of the reaction, a misconception about the relative atomic / molecular mass, and 16 misconceptions about moL Test results c2 indicate the consequences of stoichiometric misconceptions proved to be independent of sex differences but depend on language used and jejang class at the level of 5%. Students using Indonesian and 3rd graders had a smaller chance of misconcepting stoichiometry.
