Abstract

The knowledge transfer of chemistry with unfamiliar topics may cause students to struggle to understand it. Conversely, if the concepts learned are associated with local wisdom through project assignments, it will produce meaningful learning. This study aims to analyze: the activities, learning outcomes, and students' and teachers responses to the ethnoscience-PjBL learning model. The research type is descriptive with a qualitative approach. The research subjects were 21 students of class XI-MIPA. Data collection techniques used were activity observation, tests, and students and teachers questionnaires. The research instruments included activity observation sheets, test sheets, and learners and teachers questionnaire sheets. The data was analyzed by using the percentage formula. The results showed that: (1) giving questions or problems step obtained an average percentage of 91.6%. The planning step, setting the work schedule, and monitoring the project gained an average percentage of 100%. The product assessment step obtained an average percentage of 82%. The project evaluation step obtained an average percentage of 62.5% in the application of the PjBL model, (2) the students learning outcomes reached an average score of 83.4, and (3) it received a positive response from students and teachers with an average percentage of 83.2% and 94% respectively. To conclude the application of the ethnoscience-laden PjBL model on colloid received positive responses and the completeness of learning outcomes reached a percentage of 100%

Abstract

One of teachers 21st-century skills is to make qualify evaluation tools. One way to do that is by designing FTMC questions. This study aims to analyze the level of students understanding in SMAN 2 Banda Aceh on reaction rate topic by using FTMC questions. The studys approach used is qualitative and quantitative with descriptive research type. The studys subjects are 35 students of class XI MIPA-4 and 2 chemistry teachers. The data collection technique was obtained by using FTMC test, interview, student and teacher response questionnaires. The studys instruments are FTMC and interview question sheets, student and teacher response questionnaires. The data obtained was analyzed by using excel and percentages formulas. The results showed that the students who were able to understand, not able to understand, misconception, and error of the concepts are 54,5; 2,4; 35,5; and 7,6% respectively. This shows that the students level of understanding is categorized as medium in understanding the concepts. The students' and teachers' responses to FTMC test obtained an average of 46% (poor category) and 85% (good category) respectively. To sum up is that FTMC can be used to analyze students' conceptual understanding in reaction rate material
