This research was aimed to elaborate on the form of scaffolding given by learners on algebra problem-solving. The approach used is descriptive qualitative. The study conducted in a junior high school in Malang Regency with 25 students and only two students were selected as research subjects to be given scaffolding level 2. Data collection method begins by requiring learners to solve algebra and next identify the pattern of mistakes or mistakes. Learners who have wrong answers, used as research samples. The results prove the form of scaffolding given the subject. If the subject experiences an error in understanding the problem, the scaffolding is given asking the subject to re-read the problem properly and carefully and give direction questions. However, if the subject has difficulty in making the planning of the settlement, the scaffolding given is giving the subject the opportunity to rearrange the design of the right answer. If the subject experiences an error in carrying out the planning, the scaffolding given is asking the subject to pay attention to the mathematical concept and to be careful in operating algebra.

The research problem at Junior High School 29 Padang is the science learning process that takes place centered on the teacher, the low learning competency of the students, has not used a learning model that contains sains literacy, and low scientific literacy skills. Efforts that can be done are applying the problem solving learning model with scientific literacy. This research was conducted at Junior High School 29 Padang in material of KD 3.6 about additives and addictive substance. This research is an experimental research using the Randomized Control Group Posttest Only Design. The study population was all grade VIII students of Junior High School 29 Padang. Sampling was taken by using purposive sampling technique. Class VIII.3 as the experimental class and class VIII.5 as the control class. The instruments used in the form of posttest questions, observation sheets. The research instrument used was a test of learning outcomes. The research instrument used was a test of learning outcomes. The results of the t test were known that in the knowledge competency tcount> t table (3,02>1.67). the attitude competency tcount> t table (5.38>1.67) and the skills competency tcount> t table (4,39>1.67). This showed that the hypothesis was accepted. So, it can be concluded that the application of a problem solving model with scientific literacy on additives and addictive substance can improve the competency of knowledge, attitudes, and skills of Junior High School 29 Padan students.

This article is derived from the research result entitled “The Application of Problem Solving Approach in Improving Junior High School Students’ Mathematical Communication and Disposition Skill”. The research is purposed to see and analyze if there are some improvements in mathematical communication and disposition skill achievement of the students who have been treated using problem solving approach compared to the students who are still treated using conventional approach. The population of the research is all students at a junior high school in Subang regency. Out of these students,  40 students of class VIII D were chosen randomly as the experiment class, and 41 students of class VIII C have also been randomly chosen as the control class. The data in this research have then been analyzed using parametric and non-parametric statistic. The result of this analysis has shown that the achievement of experiment class students’ mathematical communication and disposition skill is better than the achievement of the control class students. The experiment class students’ mathematical disposition is also better than those of the control class. Lastly, the result also shows that there is some kind of correlation between the mathematical communication and mathematical disposition on the level of medium.
