Project based learning (PjBL) is a learning model that makes students the subject or center of learning, emphasizing the learning process that has a final result in the form of a product. That is, the students are given the freedom to determine their own learning activities, work on collaborative learning projects until the results are obtained in the form of a product. That is why the success of this learning is greatly influenced by the activity of the students.
2.2 The Definition of Project Based Learning
According to the Experts The experts may have different interpretations of the meaning, but the basic core remains the same. Project based learning is a learning model in the form of real tasks such as project work, group work, and in-depth to get a meaningful learning experience. Project-based learning (PBL)”is a student-centered pedagogy that involves a dynamic classroom approach in which it is believed that students acquire a deeper knowledge through active exploration of real-world challenges and problems”. It is a style of active learning and inquiry-based learning. PBL contrasts with paper-based, rote memorization, or teacher-led instruction that presents established facts or portrays a smooth path to knowledge by instead posing questions, problems or scenarios.(3)
Thomas Markham (2011) describes project-based learning (PBL) thus: "PBL integrates knowing and doing. Students learn knowledge and elements of the core curriculum, but also apply what they know to solve authentic problems and produce results that matter. PBL students take advantage of digital tools to produce high-quality, collaborative products. PBL refocuses education on the student, not the curriculum a shift mandated by the global world, which rewards intangible assets such as drive, passion, creativity, empathy, and resiliency. These cannot be taught out of a textbook, but must be activated through experience.
Blumenfeld et al (1991) states on the processes of PBL: "Project-based learning is a comprehensive perspective focused on teaching by engaging students in investigation. Within this framework, students pursue solutions to nontrivial problems by asking and refining questions, debating ideas, making predictions, designing plans and/or experiments, collecting and analyzing data, drawing conclusions, communicating their ideas and findings to others, asking new questions, and creating artifacts." According to Goodman and Stivers, it is a teaching approach built on learning activities and real tasks that provide challenges for students related to daily life to be solved in groups.
It certainly contains the purpose to be achieved. The purpose of project based learning is as follows.
1. Training students' proactive attitude in solving a problem.
2. Sharpening the ability of students in explaining a problem in class.
3. Increasing the activity of students in class in solving complex problems until real results are obtained.
4. Honing or sharpening the students' skills in using tools and materials in class to support their learning activities.
