This study aims to analyse the studentsâ€™ mental model of students in SMA 42 Jakarta in the implementation of Learning Cycle 8E learning model on salt hydrolysis learning. This research was conducted in first semester of 2016/2017 academic year. There are 36 students of year XI in MIPA 5 was involved in the study. This qualitative research was conducted with the data collection of writing-drawing technique, in-depth interviews, classroom observation, student journal reflective. The Miles and Huberman data analysis was employed with quality standards of data reduction, display data, and verification. Class observation conducted before and after the learning Cycle 8E was implemented for understanding, the characteristics of students and classroom learning environment. The interview technique was conducted to have deep understanding the studentsâ€™ mental model. The result showed that the students developed understanding on the concept of hydrolysis reaction process and pH of salt solution which were generated categories of understanding, not understanding, and misconception. The three categories are seen from the four stages of the learning Cycle 8E which are explore, elaborate, extend, and explain. studentsâ€™ understanding and mental model development are influenced by the learning environment and prior knowledge. This model also has developed studentsâ€™ soft skills of empathy communication, critical thinking and collaboration skills.

This study aims to determine the effect of concept-based reasoning through learning strategy Process Oriented Guided Inquiry Learning (POGIL) to student achievement on the redox subject. This type of research is a quasi-experimental research with a Non-equivalent Control Group Design. The sampling used purposive sampling technique, which obtained by two classes, one as control class using Guided Inquiry Learning (GIL) and the other as experiment class using Process Oriented Guided Inquiry Learning (POGIL). Generated data during the study was analyzed by using descriptive and inferential statistical analysis of t-test. The average posttest grade of the control class is 66.91 while in the experimental class is 71.30. The results showed that there was a difference of chemistry learning achievement in control class and experiment class with tcount = 3.0810; ttable = 1.668 (tcount> ttable). The existence of these differences indicates that the application of concept-based reasoning through Process Oriented Guided Inquiry Learning (POGIL) strategy has a positive effect to students learning achievement on the redox subject.

The aim of this study was to determine the influence of Project Based Learning on creative thinking skills of student on colloid concept. The method used in this study was quasi experiment with non-equivalent control group design. The population in this study was second semester students of SMAN 5 in Bekasi of Academic Years 2014/2015. Samples are class XI MIA-4 as the experimental class (given treatment by project-based learning model), and class MIA XI-2 as the control class (given treatment by lecture method). Data collection techniques were gained through an essay test instrument. Data value of the average pretest-posttest control group and experimental group were analyzed using t-test. The average of pretest score for control class is 19.89 and experiment class is 18.11, while the average of postest score of control class is 24.5 and experimental class is 29.35. The t-test result showed that tcount (7.35) was greater than ttable (2.0049) with significance level 5%, so the research hypothesis which states that there are significant influence of project-based learning to the creative thinking skills of students on colloid concept are accepted. In order to obtain the greatest number of information about creative thinking skills, when implemented project based learning must consider several things, that are: time management, formulation of the problem, step of project work, and assessment systems should be informed to the students in a clear and focused so that students can understand and have a passion in running the project. Keywords: Project Based Learning, Creative Thinking, Colloid.
