Physics is one of a branch of science which uses much of mathematical concept. Usually, the concept of physics is expressed in a mathematical equation; it will make physics easier to be understood. Therefore, the students need to understand about mathematical modelling to help them understand physics. Students who take fundamental physics and physics laboratory course required to understand the concept of feedback that is mathematically expressed in differential equations. However, most of the students have not been taught the concept of differential equations at early semester. Therefore, we are interested in reviewing the use of mathematical modelling with a spreadsheet in the case of feedback that is integrated with laboratory practice. The results of this study indicate that students gave positive perceptions and improve their ability in understanding the concept of feedback that is mathematically expressed in the differential equation.

Students can use drawing–based modeling to learn a pair of interacting population known as predato–prey system while they usually conducted practicum using diagram of organisms. This study was to explore students’ argumentation and students’ understanding on the concept of the ecosystem. The study was conducted quasi – experimental using the matching – only post-test – only control group design. The participants consist of 60 grade 10 senior high school students in Subang, West Java. They are placed into two groups, 30 students in the experimental group and 30 students in the control group. Data was collected through argumentation test and selected response test for assessing students’ understanding. Students’ argumentation were analyzed using Toulmin’s argumentation pattern and statistical analysis. The result showed there is no significant difference between the experimental group and the control group for students’ argumentation. Most of the students are predominantly at level 2. But the coherency of arguments of the experimental group is more coherent than the control group. It means that the students in experimental group can make logical claim and supported by the correct and relevant grounds (data, warrant, and backing). The result of students’ understanding showed there is a significant mean score between the experimental group and the control group whether 72.33 for the experimental group and 62.13 for the control group

Problem-solving ability in mathematics is a primary means to understand a problem and develop the students ' ability in solving a problem. Step in solving problems are categorized to understanding the problem, devising a plan, carrying out the plan and reflection. This research used a descriptive method aimed to identify the problem-solving ability among junior high school students and review from students self-regulated learning (SRL).The subjects of the research were taken by one student in each SRL category (high, medium, and low) which then given the problem-solving test and the result was triangulated by interview. Based on the research, it can be stated that the students with high self-regulation can solve a mathematical problem by applying first indicator, the second indicator, third indicator, but they cannot apply the fourth indicator. The students with medium self-regulation can apply the first indicator and second indicator while they are still having the problem in third indicator and fourth indicator. The students with low category self-regulation cannot apply all of those in solving the mathematical problem.

Arguments are one of the important purposes in the modern era of learning because it is the basic step to promote student’s critical thinking process and science literacy. Argumentation process can be trained through interactive dialogue that provides opportunities for students to argue. This research aims to change oral argumentation process in biology class of high school through the application of the Socratic Dialogue. The participants were students of grade XI science in one high school located in Surakarta, selected purposively. A classroom action research was done collaboratively between student teacher, lecturers, and teacher, follow the spiral cycles of research by Stephen Kemmis. During the implementation of research, the audio recorder has prepared to record the dialogue and arguments of the students. Next, data recorded that was converted to a dialogue transcript analyzed qualitatively using the Toulmin Argumentation Patterns (TAP). Another data source is teacher’s reflective diaries that contained notes during the learning process. The result shows that student’s oral argumentation process found were only claiming supported by weak warrants. Implementation of the Socratic Dialogue brings positive changes in oral argumentation process of the students, proven by the complete argumentation pattern include claims, data, warrants, backings, and rebuttals at the end of the research cycle. A classroom action research which is developed collaboratively and implement interactive dialogue also inquiry learning is highly recommended to change student’s oral argumentation process.
