The relationship between students' problem solving skills and scientific attitude with students' learning outcomes on stoichiometry at tenth grade at high school in Boyolali, Central Java, Indonesia

Student's learning outcomes are influenced by several factors, both internal and external. Problem solving skills and scientific attitudes are internal factors affecting students' learning outcomes. This was a quantitative research with the correlational approach and quantitative descriptive method. The populations were grade X science program students at SMA Negeri 1 (Senior high school) Boyolali, Surakarta, Central Java, Indonesia, academic year of 2019/2020. The data were analyzed with the correlation and regression analysis. The results showed the significant positive relationship between problem solving skills with students' learning outcomes with the correlation coefficient value of 0.845 and determination coefficient of 71.4%; the significant positive relationship between scientific attitude with students' learning outcomes with the correlation coefficient value of 0.926 and determination coefficient of 85.7%; and the significant positive relationship between problem solving skills and scientific attitude with students' learning outcomes with correlation coefficient value of 0.936 and determination coefficient of 87.5%. The effective contribution of problem solving skills was 20.45%, and the scientific attitude was 67.05%. The relative contribution of problem solving skills was 23.4%, and the scientific attitude was 76.6%.
