Abstract

This study intents to describe the feasibility of student activity sheet oriented in problem solving in the heat and its displacement for 7th grade in junior high school. It is reviewed by several aspects, those are validity aspect, practicality aspect, and effectiveness aspect. Validity aspect is reviewed by result of validation. Practicality aspect is reviewed by direct observation result of student activities when using LKS oriented in problem solving. Effectiveness aspect is reviewed by the result of student response. student activity sheet oriented in problem solving in the heat and its displacement contains series of duty which the completion should use problem solving. Those are the stage of understood the problem, device a plan, carry out the plan and look back. The method of study used in this study is R&D method (Research and Development) proposed by Sugiyono (2012: 297). This method consists seven stages, those are potency and problems stage, collecting information stage, product design stage, validating of product design stage, revising product design stage, product trial stage, and revising product. This study uses a limited product trial which is held in SMPN 21 Surabaya. The instrument of study is validation sheet, direct observation sheet of students activities and the questionnaire responses of students. The data were analized through descriptive quantitative method. The result of study shows that validation of LKS oriented in problem solving of heat and its displacement  based on didactic aspect, construction and technical, the precentage of each aspects sequentially are 90,7%, 91,6% and 91,7% with decent interpretation. The practicality of LKS oriented in problem solving in heat and its displacement viewed from direct observation result of student activities when using LKS oriented in problem solving with decent interpretation. The effectiveness aspect of LKS oriented in problem solving in heat and its displacement viewed from the students response earn by the precentage of avarage 90% with strongly interpretation. It can be concluded that LKS oriented in problem solving in the heat and its displacement for 7th grade in junior high school is feasible to be used as a learning tool because it is valid, practical and also effective. Keywords: Student Activity Sheet (LKS), Heat and The move, Problem Solving
