Effectiveness of Problem Based-Assisted Instruction Student Worksheet Guided-Inquiry-Based Learning in Chemistry
Abstract: This study aims to
determine the effectiveness of problem-based learninginstruction-aided student
worksheets based guided-inquiry in learning chemistry. This study was an
experimental study. The study design using posttest only control group design.Treatment
group and control group is selected by cluster random sampling. The population in
this study is a class XI student of a school in a city in Central Java. Data
were collectedby documentation, observation, testing, and questionnaires.
Learning outcomes measured inthis study include knowledge, attitudes, and
skills. Posttest results of data analysis showed that the treatment group
classical completeness of 82.86% and the control group of 58.33%.Results of
votes on the attitude of the treatment group of higher-class control while
beingpolite treatment group lower than the control group. Skills treatment
group is higher than the control group in all aspects. Therefore, the problem
based learning-instruction-aidedstudent worksheets based guided inquiry
learning is less effective in chemistry.
