This research aims to enhance students’ critical thinking skills of SMP Islam Abhariyah on the academic year 2015/2016 through the application of the generative learning model. Research method used was classroom action research (PTK). This research was conducted in two cycles. Each cycle consist of planning, implementating, observating, and reflecting. Data learning activities of the students and teachers’ activities obtained by observation, while data on students’ critical thinking skills test was obtained by an evaluation at the end of each cycle. The subject of this study was 28 students in VIII-B class. Application of the generative learning model in this study considered as successful if the value of critical thinking skills of the students at a minimum categorized as critical. The data for student’s critical thinking skills was accomplished by using an essay test, and the average value of students is 41.96 (categorized very less critical) whit classical completeness achieved only 3,57% in the cycle I and in the cycle II showed the average value of the students is 68,92 (categorized critical) whit classical completeness increased to 85,71%. Research data of student’s activities was taken by using the student’s observation sheet. The average score in the cycle I is 46.50 (categorized as fairly active) and in the cycle II is 66.00 (categorized as active). The data of teacher’s activities was taken by using teacher’s observation sheet. The presentation of learning material is 64,28% (categorized as good) in the cycle I and 91,06% (categorized as very good) in the gathering II. Thus, the conclusion to this study is the application of the generative learning model can improve students’ critical thinking skills.

This study aims to produce an essay test instrument for critical thinking skills on chemical bonding material and to know the validity, reliability, distinguishing features, and the difficulty level of the test instrument. The research method uses the ADDIE model with five stages namely analyze, design, develop, implementation, & evaluation. In this research formative evaluation is done, meaning that the evaluation stage is carried out at the end of each stage. The test developed in the study consisted of eight essay items, referring to 10 indicators of critical thinking according to Ennis. Validation of items was done by three validators. Based on the validity according to the experts obtained an average of every aspect, namely 95% material, 96.87% construction and 91.15% language with an overall average score of 94.34% validation has a valid category. Eight valid questions were tested on 20 students. The calculation of the reliability coefficient (r11) with the Alpha Cronbach formula was obtained at 0.65 in the high category, the distinguishing power had an average value of 0.26 in enough categories and the difficulty level of the questions had an average value of 0.42 in the medium category. The developed test instrument is declared valid, reliable, has a good differentiating power, and the level of difficulty of the questions that are being made so that it can be used as a measuring tool to determine students' critical thinking skills.Key word: Research & development, critical thinking test instrument,chemical bonding

The aim of this research is to describe the feasibility of learning materials based on 5E learning cycle model to improve student concept mastery and critical thinking skills of grade XI even semester SMKN 2 Tarakan on rate of reaction topic. This research is development research using 4D models as instructional design. The test design of the implementation of the teaching materials use one group pretest-posttest design. The result of this research is Lesson Plan (RPP), Handout, and Student Worksheets (LKS) categorized good. Concept Mastery Test and Critical Thinking Skills Test categorized valid. Handouts and student worksheets have high legibility. Implementation of RPP is good. Prominent student activity in learning based on 5E learning cycle model are reading (looking for information, etc.) (15%), do an experiment to test the hypothesis in groups (13%), and express opinions or communicate information in discussion (13%). Students’ response to learning were very good. Classical completeness concept mastery is 91% with an average score 79.61 and improvement average score (gain) is 0.8 (high category). The average score of critical thinking skills is 82.44 and improvement average score (gain) is 0.8 (high category). Obstacles in the learning based 5E learning cycle model are the number of students are many and less effective of classroom management so there are students who are less attention; lack of lab tools; and obstacles in the learning time, because the number of students are many so it take a lot of time to divide lab tools, lab materials, handouts, worksheets, test questions, and questionnaires. Based on the result of the analysis data can be concluded that learning materials based on 5E learning cycle model produced is feasible so it can be used in learning to improve student concept mastery and critical thinking skills.Penelitian ini bertujuan untuk mendeskripsikan kelayakan perangkat pembelajaran berbasis model learning cycle 5E untuk meningkatkan penguasaan konsep dan keterampilan berpikir kritis siswa kelas XI semester genap SMKN 2 Tarakan pada materi pokok laju reaksi. Jenis penelitian adalah penelitian pengembangan perangkat pembelajaran. Model pengembangan perangkat yang digunakan adalah model 4D, tetapi hanya sampai tahap pengembangan (develop).  Uji coba perangkat pembelajaran di dalam kelas menggunakan rancangan one group pretest-postest design. Hasil penelitian menunjukkan bahwa RPP, Handout, dan LKS berkategori baik. Tes penguasaan konsep dan tes keterampilan berpikir kritis berkategori valid. Keterbacaan handout dan LKS tergolong baik. Keterlaksanaan RPP tergolong baik. Aktivitas siswa yang menonjol adalah membaca (mencari informasi dan sebagainya) (15%), melakukan percobaan untuk menguji hipotesis secara berkelompok (13%), dan menyampaikan pendapat atau mengkomunikasikan informasi kepada kelas dan guru dalam diskusi kelas (13%). Respon siswa terhadap pembelajaran sangat baik. Ketuntasan klasikal penguasaan konsep adalah 91% dengan skor rata-rata 79,61 dan skor rata-rata peningkatan (gain) 0,8 (kategori tinggi). Rata-rata skor keterampilan berpikir kritis sebesar 82,44 dengan skor peningkatan 0,8 (kategori tinggi). Kendala dalam pembelajaran berbasis learning cycle 5E adalah jumlah siswa yang cukup besar dan pengelolaan kelas kurang efektif sehingga masih ada siswa yang kurang terperhatikan, kurangnya alat-alat praktikum yang dibutuhkan, serta kendala dalam waktu pembelajaran, dengan cukup banyaknya siswa sehingga waktu yang diperlukan menjadi lebih banyak untuk membagi alat, bahan praktikum, handout, LKS, soal tes, serta angket. Berdasarkan temuan hasil penelitian dapat disimpulkan bahwa perangkat pembelajaran berbasis model learning cycle 5E yang dihasilkan telah layak dan dapat digunakan dalam pembelajaran untuk meningkatkan penguasaan konsep dan keterampilan berpikir kritis siswa.
