Berdasarkan observasi yang dilakukan pada SMP Lentera Way Pengubuan, ditemukan bahwa siswa belum mampu menuliskan strategi penyelesaian suatu pernyataan atau pertanyaan sesuatu prosedur penyelesaian dengan tepat dan lengkap. Selain itu, siswa masih keliru dalam menuliskan persamaan dan simbol dengan tepat dan belum mampu menyajikan representasi visual berupa grafik berdasarkan pernyataan yang ada. Oleh karena itu, peneliti melakukan penelitian yang bertujuan untuk menyelidiki bagaimana implementasi metode drill meningkatkan kemampuan komunikasi matematis siswa. Metode penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK). Penelitian dilakukan pada 17 Juli 2017 sampai 04 Oktober 2017. Adapun subjek penelitian adalah siswa kelas VIII SMP Lentera <span lang="IN">Harapan </span>Way Pengubuan yang berjumlah 11 orang.

This study aims to determine grade IX students' response to the application of problem-based learning in economy and to determine the increase students' critical thinking skills through problem learning methods. The design of this research is Class Research (TOD), with the subjects of 31 grade IX students at one Christian junior high school in the city of Tangerang. Research instruments used in the application of problem students' daily test scores, surveys, feedback from supervising teachers and fellow students, interviews with mentor teachers, and journal reflections. Analysis of the data used is descriptive analysis, the value of students' daily tests, observations, interviews and students'questionnaires.The results showed that students' response to the problem-based learningcould improve critical thinking skills of students in learning economy. It could be seen from the increase in students' critical thinking skills in both students' ability questions, answer questions, analyze and solve problems presented by the author.Keywords: Application of problem think critically, learning in economy. ABSTRACT This study aims to determine grade IX students' response to the based learning in economy and to determine the increase students' critical thinking skills through problem-basedThe design of this research is Class-Action Research (TOD), with the subjects of 31 grade IX students at one Christian junior high school in the city of Tangerang.

Analysis of the data used is descriptive analysis, the value of students' daily tests, observations, interviews and uestionnaires.The results showed that students' response could improve critical thinking skills of students in learning economy. It could be seen from the increase in students' critical thinking skills in both students' ability to ask questions, answer questions, analyze and solve problems presented Application of problem-based learning, the ability to , learning in economy.
As an educational institution that teaches Christian values, Christian schools can play a role in building the character of the nation through education and science in accordance with Christian values. For those role it is necessary for the schools to employ committed human resources. Most of previously done research on work engagement involved factors of leadership style and job satisfaction, yet, very few included organizational culture. This research aimed to determine the effect of servant leadership, organizational culture and job satisfaction on work engagement. The research subjects were 63 teachers at junior high and senior high Christian schools located in West Jakarta. The research design used the path analysis through PLS-SEM method. The results showed that the servant leadership and organizational culture have a positive effect on job satisfaction and work engagement, but lacking evidence to prove the job satisfaction effects the work engagement. Therefore, to improve the teachers’ work engagement, one need to pay attention on two key factors: the leadership style that serves from the principal and conducive organizational culture.
