THE DEVELOPMENT OF EXPERIMENT WORKSHEET WIHTIN INQUIRY ORIENTATION TO EXERCISE HIGHER ORDER THINKING SKILLS IN FACTORS THAT AFFECTING REACTION RATE TOPIC OF 11th GRADE’ SENIOR HIGH SCHOOLSTUDENT

Abstract

This study aims are to know the feasibility of Experiment Worksheet within Inquiry Orientation to Exercise Higher Order Thinking Skills that had been developed as a learning media on factors that affecting reaction rate topic. The research method that used was 4-D method (define, design, develop, and desseminate). But this research was conducted until develop step only, namely development. This worksheet had been reviewed and validated by 2 chemistry lecturers and a chemistry teacher.Then it has been tested on 12 students in11th grade of Bahauddin Senior High School Taman Sidoarjo.The result of this research showed that this Worksheet had been developed is feasible tobe used as learning media. This was shown based on the assessment result from chemistrylecturers and teacher, viewed from teoretical validity including content criteria, presentation criteria, inquiri orientation criteria, and higher order thinking skill criteria, each of that percentage was 93,20%, 90,67%, 86,86% and 93,41%.  While empirical validity was student responses which supported by student activities including content criteria, presentation criteria, inquiri orientation criteria, and higher order thinking skill criteria, each of that percentage was 99,31%, 89,41%, 83,33% and 93,75%. Result of higher order thinking skill test by overall is 83,33%.

Penelitian ini bertujuan untuk mengetahui kelayakan  LKS eksperimen bersorientasi inkuiri untuk melatihkan berpikir tingka ttinggi yang dikembangkan sebagai media pembelajaran pada mater ifaktor-faktor yang mempengaruhi laju reaksi. Metode penelitian yang digunakan adalah metode 4-D (define, design, develop, dan desseminate). Namun pada penelitian in ihanya terbatas sampa itahap develop saja yaitu pengembangan. LKS ini ditelaah oleh 2 dosen kimia dan 1 guru kimia dan juga divalidas ioleh 2 dosen kimia dan 1 guru kimia .LKS in idiujicobakan pada 12 orang siswa kelas XI SMA Bahauddin Taman Sidoarjo. Hasil penelitian menunjukkan bahwa LKS yang dikembangkan ini telah layak digunakan sebagai media pembelajaran. Persentase hasil penilaian dosen kimia dan guru kimia, yang ditinjau dari validitas teoritis dalam criteria isi, criteria penyajian, criteria berorientasi inkuiri, dan criteria keterampilan berpikir tingkat tinggi yang memperoleh presentase berturut-turut sebesar 93,20%, 90,67%, 86,86% dan 93,41%.  Sedangkan validitas empiris yaitu respon siswa yang didukung oleh hasi laktivitas siswa dalam kriteria isi, criteria penyajian, criteria berorientasi inkuiri, dan criteria keterampilan berpikir tingka ttingg imendapat hasi lsangat layak dengan persentase berturut-turut sebesar 99,31%, 89,41%, 83,33% dan 93,75%. Pada hasi ldari tes keterampilan berpikir tin kat tinggi secara keseluruhan adalah 83,33%.
