Abstract

The 21st century requires four specific skills namely literacy, inventive thinking, effective communication, and high productivity. Literacy includes basic literacy, scientific literacy, economic literacy, technological literacy, visual literacy, information literacy, and multicultural literacy. The purpose of this research is to produce a chemical literacy assessment instrument on colloidal system material that is suitable for use as a chemistry measurement tool for high school students who meet the requirements of feasibility validity, reliability, and level of difficulty. This research is a form of development research or R&D (Research and Development). The development model used in this research is the Oriondo and Dallo Antonio instrument development model, which has five stages: 1) planning the test, 2) trying out the test, 3) establishing empirical validity (establishing test validity), 4) determining reliability (establishing test reliability), 5) interpretation of scores (interpreting the test scores). The data collection instruments used in this study were questionnaire validation sheets, question validation sheets, and development results questions. The reliability value of the person from the score obtained in the trial was 0.55 indicating that the reliability of the person or students was in the medium category. Reliability value item was 0.48 in the medium category. Overall, the average reliability value or Cronbach Alpha is 0.69 in the sufficient category. So it can be concluded that the score obtained from the assessment instrument is reliable because it has fulfilled a minimum coefficient value of 0.60.

Abstract

In order to adapt to the rapid development of technology and information in the 21st century, various abilities and skills are required.As an instrument of social change and scientific attitudes, education has a responsibility to facilitate every learning process so that it is oriented to the needs of the times.This study uses a quantitative descriptive method that aims to analyze the results of Science Process Skills and Scientific Attitudes of students through the application of STEM (Science, Technology, Engineering and Math) integrated Project-Based Learning.The subjects in this study were 70 students who took Basic Physics lectures using a sampling technique, namely total sampling.The content validity of the instrument through analysis of the Vaiken index obtained an average index of 0.84 in the High category for the Science Process Skills instrument and an average index of 0.83 in the High category for the Scientific Attitude instrument, indicating that the instrument was declared valid and feasible.used.The results of the Science Process Skills assessment of students obtained the highest average in the Conducting Experiment aspect with a score of 89.29 and in the Very High criteria, while for the average of all aspects of Science Process Skills a score of 83.72 was obtained in the High criteria.For the results of the Scientific Attitude assessment, students obtained the highest average in the Curious Attitude aspect with a score of 94.29 and in the Very High criteria, while for the average of all aspects of Scientific Attitude, a score of 89.71 was obtained in the Very High criteria.Based on these results it can be stated that the implementation of PjBL – STEM has a positive impact and contribution to Science Process Skills and Scientific Attitudes of Students.
