The analysis on implementing discovery learning-based learning instruments in improving students’ creative and innovative thinking skills in completing problem of simple multiplication by using jaritmatika

Innovative creative thinking skills play an important role in supporting students in solving mathematical concepts, especially simple multiplication operational problem with Jarimatika . The researchers applied mixed methods with a sequential explanatory design. Research subjects were 28 students in the experimental class and 26 students in the control class. Data were collected through validation sheet, test, documentation, and prerequisite test. The research result indicated that after the implementation of Discovery Learning-based learning instruments, the percentage of students’ innovative creative thinking for the control class was 11.54% for the very creative innovative level, 69.23% for the innovative creative level, 19.23% for the enough innovative creative level, and 0% for less or not innovative creative level. While the experimental class far exceeds the control class, 39% for the very creative innovative level, 57% for the innovative creative level, 4% for the enough creative innovative level, and 0% for less or not innovative creative level. The independent sample t-test score from the post-test shows that there is a significant difference between the control class and the experimental class with a t-count value of -4,965 with a significance value of 0,000. The significance value is smaller than the α value (0.05). This shows that there is an average difference between the control class and the experimental class after receiving treatment (post-test). The negative sign on the t-value indicates that the average experimental class is higher than the control class. It can be concluded that the application of Discovery Learning-based learning instruments can improve elementary school students’ innovative creative thinking skills in solving simple multiplication operation problem with Jaritmatika .
