This research has been conducted to analyze students' problem-solving abilities in direct current electricity in STEM-based learning. The implementation of STEM in this research is to train the domain of scientific practices and engineering practices that are associated with model problems and project-based learning. The research method used was pre-experiment with the design of one group pretest-posttest. The subjects of the research consist of 27 students at the 10th grade of one of the Vocational Schools in Kabupaten Bandung Barat. The instrument of problem-solving ability in this study are four structured description questions, each of which consists of 5 questions, indicators of problem-solving ability, namely visualize the problem, describe the problem in physics description, plan the solution, execute the plan, and check and evaluate. As a result of the research, it was found that there was an increase in students' problem-solving abilities with the application of the integration model problem and project-based learning in STEM-based learning.

This research is motivated by the low ability to solve mathematical problems in fifth grade students of SDN Kaliabang Tengah 1 Bekasi Utara. Seen when researchers provide exercises in the description of mathematical problems in the form of stories on fraction material. There is still a lack of student knowledge regarding fractional material. When working on the story problem students simply add up or subtract the denominator by the denominator and the numerator by the numerator, without first equating the denominator. Students have not been able to solve problems correctly and many are still wrong. The lack of students' ability to infer results obtained from mathematical story problems. Enthusiastic students are lacking in solving mathematical story problems that are considered difficult. This study aims to improve the ability to solve mathematical problems using problem solving models in fifth grade students at SDN Kaliabang Tengah 1, North Bekasi. The research method uses Classroom Action Research (CAR) which consists of 3 cycles.. The conclusion of this study is the problem solving model can improve the ability to solve mathematical problems in fifth grade students at SDN Kaliabang Tengah 1 Bekasi Utara.

<p>This research aimed to examine students’ perceptions of their life skills while attending project-based learning (PBL) schools. The study focused on three questions including: 1) What are students’ perceptions of their development of life skills in project-based learning schools? 2) In what ways, if any, do students perceive an increase in their life skill development over a one-year period of time? 3) What relationship, if any, is there between grade level and students’ perceptions of their life skills? The subjects were 275 6-12 students from two project-based learning charter schools in Minnesota. One school was located in a rural location; the other in an urban location. The triangulating data collection methods included a Likert-scale survey, semi-structured interviews, and focus groups. Quantitative analysis using SPSS were used to analyze the survey data. Qualitative analysis methods used were coding and identification of emergent themes. Qualitative results showed perceptions of most improved skills as time management, collaboration, communication, and self-directedness. Quantitative data results showed most improved skills within an academic year as responsibility, problem-solving, self-directedness, and work ethic. Self-directedness was the single skill that was evident in all data results. The results showed students’ perceptions of their life skills were positive and that project-based learning helped them develop multiple life skills including, but not limited to communication, collaboration, problem-solving, responsibility, and time management. Implications of this research suggest that project-based learning has a positive influence on students’ life skills development across 6-12 grade levels and helps prepare them to be successful in the 21<sup>st</sup> century global community and economy.</p>

This paper uses the mathematical software Maple as the auxiliary tool to study the differential problem of four types of rational functions. We can obtain the closed forms of any order derivatives of these rational functions by using binomial theorem. On the other hand, we propose four examples to do calculation practically. The research methods adopted in this study involved finding solutions through manual calculations and verifying these solutions by using Maple. This type of research method not only allows the discovery of calculation errors, but also helps modify the original directions of thinking from manual and Maple calculations. For this reason, Maple provides insights and guidance regarding problem-solving methods.

SOLO Taxonomy is one of the frameworks used in analyzing the quality of responses in problem solving. This research aim to analyze the student’s responses level in doing problem solving item based on SOLO Taxonomy overviewed from motivation to learn. The research method used in this study was a qualitative research with the data sources of this study were 75 students period 2016/2017. The results of the study showed that student’s responses in doing problem solving wave concept at prestructural level is 62,17%, Unistructural Level is 27,63%, Multistructural level is 58,22%, Relasional level is 48,50%, and Extended Abstract level is 37,82%; Motivation to learn’s student high category are better at responding to answer item based SOLO Taxonomy than motivation to learn’s students low category.Keywords: Student’s reponses; SOLO Taxonomy; Motivation to Learn

Abstract-This research related to the development of the potential of ecopreneurship students through project-based learning. The purposeof this research is caused by unrest demonstrated by students either in the process of learning which is very flat as well as assessment of the student's active role in the learning or suggested the practice as a form of character development. Researchers take a character-based entrepreneurial environment because the research location close to traditional and modern market. Problem formulated which examined is, related how the design, implementation, as well as the obstacles that occur in this research. The research method used is the classroom action research method using designs from Lewin according to Elliot. The design research of Lewin according to Elliot in each cycle begins with planning, action, observation, and reflection. Data collection techniques used are observation, field note, and documentation study. The instrument used is the observation sheet and rubric. Based on the research that has been done shows that project-based learning model can be an alternative model which could develop the potential of ecopreneurship grade VII-A MTS. Ar-Rohmah Bandung. This can be seen from the increase in the indicators of research after two cycles with a total of eight actions. The increase occurred on the indicators create, explore, creative, innovative, and confident. The results of this research can be an alternative to developing the social studies study that allows students to explore his creativity by doing a practice jump, so that learning becomes more meaningful for teachers as a student or as a character-forming the subject of the creation of the character.Keywords: project-based learning, the potential ecoprenership.
