Abstract

This study aims to determine: (1) whether or not there are significant differences in the ability
to think at a higher level between students who are taught with worksheets based on science process

effectiveness of using student worksheets based on science process skills to improve higher order
thinking skills. This research was conducted in class V of Nurul Hasanah Tembung Private Primary
School. This study uses a quantitative approach. This research method is a quasi experiment with the
Nonequivalent Control Group Design. The population in this study was grade V private primary school

class as an experimental class and the VB class as a control class. The validity used is content validity
and reliability using Cronbach's Alpha. The analysis technique uses t-test. Based on the calculation of
the significant value of the Independent sample t test is 0,000 <0.05 and the Ngain Score calculation,
the average value of the experimental class is 74.80 with a quite effective category is greater than the
average value of the control class that is 34.04 with a category ineffective. This shows that the use of
student worksheets based on science process skills is very effective for improving higher order thinking
