Analysis of teacher’s need through student’s worksheet development based on problem based learning on acid-base material

The use of student’s worksheets based on problem based learning was expected to enable students to have problem solving skills and provide opportunities for students to think and work together (collaboration skills) during learning. This study aimed to describe the teacher’s need for student’s worksheets based on problem-based learning to support the chemistry learning process in the classroom. The type of research is descriptive evaluation, the subjects of evaluation in this study are chemistry teachers, the instruments used in this study were interviews and descriptive data analysis. The results showed that student’s worksheet based on problem-based learning were rarely used in the learning process, mostly using textbooks, androids, and PPT/LCD projectors. Making student worksheets based on problem-based learning required a long-time allocation in compiling various concepts according to the syntax of the problem-based learning model so that teachers felt less interested in making student worksheets based on problem-based learning. Meanwhile, at the time of application, the teacher must understand and master the student worksheets based on problem-based learning because it must be explained first to students before being done so that students understand how to work on student worksheets based on problem-based learning.
