PjBL and STEM learning models can overcome the lack of critical thinking skills and collaboration. Those learning models involve 4C that support students’ critical thinking skills and collaboration. This study aimed to identify the effectiveness of STEM-based PJBL models on students’ critical thinking skills and collaborative attitudes. This study was quantitative research with a descriptive method. The data had been collected using a critical thinking skills test, collaborative attitude questionnaires, and learning observation guidelines. Before performing data analysis, the researchers performed prerequisite tests consisting of the normality test, homogeneity test, variance-covariance matrix homogeneity test, N-Gain test, and effectiveness test. The basic assumption test results showed that the MANOVA test could be performed. The MANOVA test results revealed that the STEM-based PjBL learning model effectively improved students' critical thinking skills and collaborative attitudes.

The objective of the research is to find out the effectiveness of the application of guided inquiry learning models to student learning outcomes. The research method used quasi-experimental with a nonequivalent control group design type. The population covered 34 students with saturated sampling technique with a sample of 34 students. The research instrument used test questions and documentation studies as well as data analysis techniques using the independent t-test and effect size test. The results of the study showed that the application of guided inquiry-based learning models with scientific-based worksheets on the learning outcomes of Class VI natural science at SDI Bakunase Kupang was effective, in which the average test score of the control class was smaller than the experimental class at 68.24 <79.41 and based on the value of sig. (2-tailed)> α that is 0.001 <0.05, then there was a significant difference in the average value between the control class and the experimental class and the effect size test results was 0.85. Therefore, it can be concluded that the application of the guided inquiry learning model based on LKS based Scientific is effective towards the learning outcomes of Class VI Natural Sciences at SDI Bakunase Kupang.

This research aimed to describe the implementation of character education in schools, in terms of planning, implementation and evaluation of the character education. This research method used survey, it was conducted in Elementary Schools of Kupang City. Samples were selected using random sampling cluster area technique so that from a population of 134 schools selected 21 schools representing 6 existing sub-districts. The instruments used are questionnaire and interview guidelines. This research uses qualitative descriptive analysis techniques. This study resulted in; (1) The planning aspect of character education began in 2011/2012 academic year. The initiator was the education office of Kupang City in collaboration with schools' internal parties. The reason of implementing this character education were to change students' behaviours into noble people in balance with graduates expected competencies, to help students make wise decisions, and be able to distinguish between good and bad, and to cultivate leadership and responsible characters either in family, school or society.(2) Implementation aspect involved actors of implementation and target of character education including principal, teachers, officers and students. The integration of character education in schools was done through subjects' learning, habituation and extracurricular activities.(3) The evaluation phase covered impact of implementation, barriers to implementation and solutions to overcome those obstacles.Abstrak: Penelitian ini bertujuan untuk mendeskripsikan implementasi pendidikan karakter di sekolah, dari segi perencanaan, pelaksanaan, dan evaluasi pendidikan karakter.
