This research is a quasi-experimental research with a nonequivalent control group design. This research also involved two research subjects, namely the experimental class and the control class. The population of this research was the tenth-grade students of SMA Gajah Mada Bandar Lampung. The samples were determined using the cluster random sampling technique. In collecting the data, the researchers employed a critical thinking test and a Likert scale questionnaire. The research data were analyzed using the ANOVA test. The results showed that the experimental class’s average score on the pretest experienced an improvement, from  64.96 to 84.24. The PjBL model with the STEM approach improved students' critical thinking skills and self-efficacy. The improvement was marked by the average pre-test and post-test scores improvement for each indicator, from 60.86 to 81.22. The improvement of pretest and posttest scores determined by the N-gain test was 0.55 or 31%. Furthermore, the average self-efficacy score obtained by the experimental class was 135.04, or 93% within the excellent category. Therefore, it can be concluded that the PjBL model with the STEM approach influenced the tenth-grade students' critical thinking skills and self-efficacy on ecosystem learning materials.

The significance of reading comprehension for learners’ English mastery makes English teachers need to help learners to activate their background knowledge related to texts being read and promote the use of reading techniques. In this study, researchers applied the genre-based directed reading thinking activities (G-BDRTA). Genres here are oriented to provide learners with various text types for reading activities. Consequently, this study was aimed at actuating learners’ reading comprehension through genre-based directed reading thinking activities (G-BDRTA) viewed from critical thinking skills. This study was classified as an experimental study using non-equivalent control group design. This study was conducted at SMAN 1 Lingsar. There were 62 learners involved in this study. The learners were divided into two groups and each group embraces 31 learners. One group becomes an experimental group which is subjected to the G-BDRTA strategy and the other group is subjected to the control group treated using student-team-learning (STL) strategy. To find out the data, researchers used a reading test and critical thinking test as research instruments. Then, the data were analyzed using Two-Way-ANOVA. Based on the data analysis, there is a significant effect of G-BDRTA strategy on students’ reading comprehension viewed from critical thinking skills.
