Abstract

Effective argumentation in science classrooms relies on the ability of students to evaluate evidence. However, there is a gap in research concerning students’ capacity to validate evidence, particularly in the context of engineering design. Evidence validation skill is crucial for fostering reasoning and strengthening argumentation. This study aimed to explore students’ ability to investigate evidence in engineering design classrooms, drawing from their daily life experiences. This study was framed by a qualitative approach, with a case study design involving students in a coffee farming community. The students were assigned an engineering project related to coffee preparation, based on a problem statement devised by their teachers using the Engineering Design Process. Data was collected through observation of the students’ activities in the engineering classroom. Small-group discussions were held, and the data was recorded, transcribed, and analyzed using semantic gravity (SG). Our results reveal that students hailing from farming backgrounds were able to devise solutions based on their firsthand experiences in processing coffee with their families. The environment in which the students were raised plays a pivotal role in their learning. These findings underscore the importance of contextual learning in educational design. Educators should consider students’ backgrounds and experiences when planning instructional strategies.

Abstract

The lack of teaching materials use, especially in viscosity topics, has decreased students' knowledge and analytical skills in measurement. The research aimed to design a Student Worksheet (LKPD) for viscosity topics to assist and train students in measuring the viscosity of fluids. The fluids used in the experiment were biosolar, dexlite, and pertamina dex, considering that these fuels are among the most significant commodities and widely used in Indonesia. Additionally, the viscosity of diesel fuel is an important property affecting combustion and engine injection. This research employed a quantitative method using laboratory experiments to measure the viscosity values of biosolar, dexlite, and pertamina dex using the falling-ball method. The research findings were utilized to develop the LKPD teaching materials. The results showed that the viscosity values of biosolar fuel, dexlite, and pertamina dex were 3.651 cP; 3.579 cP; and 3.004 cP; respectively. These results differed slightly from the literature but were still deemed suitable for the LKPD teaching material design. The title of the LKPD teaching material used was "Viscosity of Biosolar Fuel, Dexlite, and Pertamina Dex Using the Falling-Ball Measurement Technique," and it followed the format of a cover, usage instructions, summary of the material, laboratory assignments, and questions.
