Abstract


This study aimed to determine the effect of problem solving learning with HOTS (HigherOrder Thinking Skills) oriented on the results of class X students of chemistry subject on theconcept of electrolyte solution and redox. The population are 286 high school students of class Xin Semarang. Sampling is done by cluster random sampling technique, one was selected as theexperimental class and one as a control class. The average value of cognitive learning outcomes 1051 for experimental class 84.06, while the control class 77.60. Both classes are normally distributedand have the same variance, whereas the t test of the two-part generated -ttable(-2.00)<tcount (4.32)>t table(2.00) which means there is a significant difference between the two classes. On theright side of the t test obtained tcount(4,32)>ttable(1,67) which means that the average student'scognitive learning outcomes experimental class was better than the control class. The results ofthe correlation analysis obtained r=0.5079, so it was significant with coefficient of determinationof 25.79%, which means the use of problem solving learning with HOTS oriented has contribution25.79% on the student learning outcomes, whereas 74.21% is explained by other variables. Itcan be concluded that the use of problem solving learning with HOTS oriented have positiveeffect on students' learning outcomes. Problem solving learning can stimulate students' higher orderthinkingskillssuchascriticalandcreativethinking.
