Abstract

Mastery of 21st-century skills by students is very dependent on the education and learning process. This research aims to measure the increase in students' problem-solving and self-directed learning skills. One of the biotechnology lessons that highlights the local potential of Aceh's Jrek Drien which can be a solution to overcome this problem. The research method used was quasi-experimental with a nonequivalent control group design. The population in this study was class X (Ten) students with a research sample of two classes, experimental and control classes, the research sample was determined based on convenience sampling. Data collection instruments used a problem-solving skills description test and a self-rating scale self-directed learning (SRSSDL) questionnaire. The results of the research showed that students' problem-solving skills increased with an average gain score for the experimental group of 22.44, while for the control group, it was 15.00 with the N-gain score for the experimental group being in the medium category and the control group being in the medium category of 0.320. Meanwhile, the students' self-directed learning ability obtained an average score of 81.61 for the experimental group and 79.12 for the control group. Students showed a positive response to the implementation of problem-based learning containing the local potential of Jrek Drien in the good category. Based on the research findings and results, it is stated that there is a significant difference in the increase in learning outcomes of students' problem-solving skills and self-directed learning between the experimental and control classes

Abstract

The learning outcomes in the independent curriculum expect students to have skills in processing and analyzing data and information. These skills are in line with the information processing abilities developed by Marzano (1993). This research aims to determine the level of students' information processing abilities in biotechnology learning and its relationship with students' cognitive processes. The data in this research were processed using PLS-SEM (Partial Least Square–Structural Equation Model) analysis. Based on the results of the analysis, the instruments used to test information processing abilities, level 1 retrieval and level 2 comprehension cognitive systems, metacognitive systems and self-systems are valid and reliable. However, the level 3 analysis and level 4 knowledge utilization cognitive systems showed invalid and unreliable results so no further evaluation was carried out at these two levels. The results of the inner model analysis show that increasing information processing abilities have a significant and linear relationship to increasing cognitive processes. The relationship between information processing abilities and cognitive processes from the highest respectively is students' comprehension (L2), self-system (L6), metacognitive system (L5), and retrieval (L1).
