This aims to determine the effect of the 5E learning on student learning Autonomy. The research subjects are 84 PGSD students. 5E Learning applicants with the syntax of Engagement, Exploration, Exploration, Elaboration, and Evaluation were carried out in advanced science courses in the second semester. Research with the type of quasi experiment using questionnaires as a measure of student learning Autonomy. The results showed that the mean score of the control group and the experimental group had increased. The Mann-Whitney U test obtained a significance of 0.039 and the effect of the 5E learning showed a high category with score of N gain is 0.98. it can be concluded that the 5E learning affects student learner autonomy.

This resarch aims to determine the effect of the 5E learning cycle on learner autonomy. Research with the type of quasi experiment using questionnaires as a measure of learner autonomy. The research subjects are 84 PGSD students. 5E Learning Cycle applicants with the syntax of Engagement, Exploration, Exploration, Elaboration, and Evaluation were carried out in advanced science courses in the second semester.. The results showed that the mean pre-test score of the control group and the experimental group had increased. The Mann-Whitney U test obtained a significance of 0.039 and the effect of the 5E learning cycle showed a high category with score of N gain is 0.98. So that it can be concluded that the 5E learning cycle affects student learner autonomy.

Observational skills are one of the indicators to know the level of achievement of science process goals. This research examines the influence of picture storybook with scientific approach through project-based learning on observational skills. The research was a quasi-experiment conducted in the second grade of the elementary school in Banguntapan Subdistrict. The samples were 265 students, 139 of experimental and 126 of control groups. The picture storybook with a scientific approach through project-based learning on observational skills was applied to the experimental group and the 2013 curriculum book from the Ministry of Education and Culture of Indonesia for the control group. The instrument used was a written test and observation. A t-test was used to analyze the effect of picture storybook with scientific approach through project-based learning on observational skills. The results of this study found that the achievement of observational skills for the experimental group was higher than the control group. The picture storybook with scientific approach through project-based learning on observational skills has a significant effect on observational skills. These findings contribute significantly to the current knowledge about the effectiveness picture storybook with scientific approach through project-based learning on observational skills to improve students' science process skills in every teaching and learning.

<em>As a high-level thinking ability, problem solving is developed at the level of primary school education, especially in the high grande. Problem solving is the concept of thinking ability by understanding the problems presented and using the right solutions with various kinds of strategy development. The purpose of this study is to analyze the problem solving of students through the results of student worksheets on green plant material. The results show that students' problem solving language is simply with a problem solving indicator framework, including: building knowledge related to issues / problems, determining keywords, determining solution strategies, and determining conclusions.</em>
