Preliminary analysis to develop student worksheet based on inquiry based learning model for 21^st century physics learning

One of the efforts to achieve 21^st century skills in learning of physics, student worksheet with the inquiry based learning model that can improve creative thinking skills. Reality in the field still finds learning in schools that have not achieved one of the 21^st century skills expected in learning of physics. The aim of this research is to obtain results of the preliminary analysis which became the basis to develop Student Worksheet. Participant of this study were physics teachers and students from several high schools in Padang. Preliminary analysis to develop student worksheet includes Teacher Reform Analysis, Learning Difficulty Analysis and Student Characteristics Analysis by retrieving data obtained through observation sheets and interviews. The data was analyzed using descriptive statistical methods. The result show the student worksheet developing by teacher has not been able to achieve 21st century skills in learning of physics.
