Students had been challenged to build a simple distillation apparatus by using project-based learning. In these project of the apparatus, they were applied their knowledges and skills to look for an alternative replacement tools, plan, build, and test the functioning of the apparatus. A simple distillation apparatus was designed and constructed by students where some tools could be replaced with used goods, such as: (1) a bunsen burner could be replaced with an spirit-wall lamp; (2) a soft drink glass bottle replaces a Pyrex flask as a distilling flask; (3) a modified plastic bottle with alumunium tube and plastic hoses replaces a glass tubing as a condenser, and (4) a modified dynamo from car toys was used as aerator with source of electric current from battery, power bank, or electric using phone charger. The apparatus already could be used to purify sea water that modeled by saline solution. The distillates were clearer and colorless compared to saline solution and did not conduct electricity. Based on that, the project was improved students’ understanding and creative thinking skills on the distillation concepts.

Project-based learning is one of the popular and promising approaches in engineering education. The current study reports on a curriculum that was designed and implemented by a graduate school to help students gain knowledge and creative thinking skills through collaboration between different majors during industrial projects in a graduate course on home appliance engineering. The students selected the topics, planned the project, conducted research, produced a prototype, and presented their results under the guidance of a group of advisors consisting of professors, technical advisors, and industry mentors. A quantitative analysis showed that this approach was effective in improving the students’ attitude toward engineering. Furthermore, a qualitative analysis showed that this learning method helped students learn how to communicate and present effectively, to flexibly approach projects, and to understand the practices of industrial research. Based on the findings, the current study discusses how the project-based learning helped students advance.

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.

The ability to think creatively is an important ability in mathematics to deal with the demands of the 21st century. One learning model that can improve students' mathematical creative thinking skills is Project Based Learning. This study aims to determine the improvement of students' mathematical creative thinking abilities through Project Based Learning using Transformation Gymnastics and Tetris GeoGebra. Research instruments used in this study is a test in the form of description, consisting of pretest and posttest that measures the ability of mathematical creative thinking including fluency, flexibility, originality, and elaboration. Data analysis includes tests of normality, homogeneity, and t-test using SPSS application assistance. The results showed that there was a significant increase in the value of students' creative thinking abilities, both in classrooms with Project Based Learning using Transformation Gymnastics and in classrooms with Project Based Learning using Tetris GeoGebra. There was no significant difference between the average posttest in the two classes. Thus, the two project tasks used in this Project Based Learning can be used in learning Transformation material.

Often we find the fact that skills gaps begin with the basic idea that many jobs exist, but skilled workers do not. The relationship exists between labor readiness, business and industrial development, and educational institutions have been around for a long time. However, this relationship cannot refute the fact that prospective employees are not ready to enter the workplace in the future. The Law of the Republic of Indonesia concerning the national education system addresses the importance of training in creative thinking skills by stating that the education system must develop the potential of students to be religious, respectful, well-educated, and competent in thinking creatively, independently, democratically, and responsibly. While empirical studies show that Indonesian students have unsatisfactory creative thinking skills. This study aims to describe how to train Creative Thinking Skills through project-based learning in preparing the Workforce to face global competition. From the results of the discussion it was concluded: 1) The government needs to be more serious in entering tertiary education and setting targets for maximum workforce readiness. 2) Educational institutions in their learning activities need to improve their mastery of high-level thinking skills in determining their educational success by improving high-level cognitive functions (metacognition, metamemory and metacomprehension, or assessing the truth of one's own memories; solving problems, or taking appropriate steps when dealing with unknown things, and think critically, or evaluate the quality of ideas). 3) For most educators today who are well connected and driven by technology, the mastery of technology literacy in education is still lacking, therefore mastery of technology literacy needs to be improved at the level of the teachers in this country. 4) Potential to integrate Project Based Learning (PBL) in the classroom to improve students' soft skills which in turn will ensure greater results for them in the future. To achieve that, their soft skills need to be improved by using the PBL approach. This approach is relevant to the concept of 21st century learning, especially in education.
