Penelitian ini bertujuan untuk menggambarkan proses berpikir kreatif siswa Hasil temuan penelitian menunjukkan bahwa: (1) Proses berpikir kreatif dari tipe kepribadian Rational. (a)Â Pada tahap persiapan subjek cenderung lebih cepat dalam memahami soal,Â dapat mengungkapkan informasi yang didapatkannya baik secara lisan maupun secara tulisan, (2) pada tahap inkubasi subjek berhenti sejenak untuk mengendapkan pikirannya sehingga dapat memunculkan ide-ide baru, bahkan sudah dapat memikirkan alternatif lain namun masih bersifat abstrak, (c) pada tahap iluminasi subjek dapat menemukanÂ ide dan membangun gagasan baru sehingga dapat mengembangkan ide danÂ pikirannyaÂ dengan cara-cara yang tidak hanya terpaku pada cara yang pernah diajarkan saja. (d) Pada tahap verifikasi subjek cenderung teliti karena berhasil mengevaluasi solusi dengan cara memeriksa kembali hasil jawaban yang telah diperolehnya. (2) Proses berpikir kreatif dari tipe kepribadian Artisan. (a) Pada tahap persiapan subjek cenderungÂ lama dalam memperoleh informasi, membaca soal secara berulang-ulang untuk memahami soal yang disajikan, subjek kurang bisa menyajikan informasi yang didapatkannya dengan tulisan dan hanya dapat menyajikan informasi secara lisan, serta menjelaskan dengan menggunakan alasan yang kurang logis. (b) Pada tahap inkubasi subjek berhenti sejenak untukmengendapkan pikirannya karena subjek lebih cepat merasa bosan dengan suasana yang menuntutnya terlalu fokus, (c) pada tahap iluminasi subjek dapat membangun solusi masalah dengan benar namun tidak bisa mengembangkan ide dan gagasannya sehingga tidak bisa menerapkan cara lain yang dimaksud pada soal dan (d) pada tahap verifikasi subjek cenderung kurang teliti karena tidak dapat mengevaluasi solusi yang didapatkannya.

The lessons learned in junior high schools that do not take into account the learning obstacles that students experience, in general teachers submit materials referring to the instructional materials in the form of a book or reference books. Therefore it is important to do a study that examines the learning obstacle for junior high school. Learning that is designed based on learning obstacle will create an optimal learning process. The purpose of this research is to analyze the learning obstacle (learning barrier) related to SMP material and its causal factors. The method used in this study using qualitative methods. Based on the research, the conclusion is as follows. about the learning obstacle analysis of junior high school students on tube and cone material. The conclusions obtained are, The difficulties experienced by students in solving the story form is as follows: (1) Difficulty understanding the concept; (2) Difficulty calculation; (3) Difficulty solving the story problem. Researchers suspected the presence of ontogenic obstacles and didactical obstacles. Difficulty in applying the formula to problem solving obtained a percentage of 16% belong to very low criteria. Difficulties in performing arithmetic operations such as addition, subtraction, multiplication, and division operations are 48.8% percentage of sufficient criteria. Difficulty solving story problem obtained percentage equal to 37% belong to low criterion. Most students do not understand the meaning of the given question. Students experience obstacle, obstacle, obstacle and didactical obstacle obstacles in solving problems with indicators applying the concept of tube and cone volumes presented in the story.

This research was based on the background of the lack of critical thinking skills of students in SMP PGRI 6 Bandar Lampung. This is caused by several factors, one of which is the selection of learning models such as conventional learning models that are continuously applied by teachers in the classroom. Efforts to address these problems, researchers aim to determine whether there is the effect of problem-based learning with cognitive conflict strategies towards students' critical thinking skills better than conventional learning. This research is a type of experimental research from Quasi Experimental design. This study uses the Pretest design - Posttest Control Group. The subjects in this study were VII grade students of PGRI 6 SMP Bandar Lampung with a total sample of 62 students. The sampling technique was carried out by means of class random techniques. Instruments used to collect data in tests of critical thinking skills. For the normality test using the Liliefors test, the homogeneity test uses a similarity test of two variances. The hypothesis test used in this study is the t-test on n-gain data. With a sample of 62 students and a significant level of α = 0.005 obtained t table = 2,0002 and the calculation results obtained by tcount = 2.50791, it can be seen that tcount> ttable then H0 is rejected. Thus it can be concluded that whether there is the influence of problem-based learning with cognitive conflict strategies towards students' critical thinking skills better than conventional learning.
