PENGEMBANGAN LKPD TEKANAN HIDROSTATIK BERBASIS KETERAMPILAN PROSES SAINS

Abstract

The Development of Students Worksheet (LKPD) Based on Scientific Process on Hydrostatic Pressure. This article is result from Research and Development (R&D) which has general objectives to produce Works sheets of students (LKPD) based on scientific process. Tool development procedure follows 4-D development model up from Thiagrajan, etc. it includes with define, design, develop, and disseminate. Model/structure of LKPD produces title, questions (observation, analysis and discussion, and conclusion). This model/structure is minimalizing the guide statement like on the experiment guide book (it's like with "cake recipe"). Two professionals in validation and two apprentices (physics teacher) showed that tool has been fulfilled with valid criteria. Limited experiment tol (hydrostatic pressure) has been fulfilled the criteria and effective. The smoothness of LKPD usage by the teacher in student's science process skill in problem summarize, hypothesize, apparatus identification, writing the process plot, and find the physics concept with answering the question in LKPD can be determined. The experiment result shows that tools which have been made had fulfilled the valid criteria, practice and effective until we can implement the material in a learning process.
