Abstract

The background of this research is learning models that are limited in variation, which makes the students less active, especially in questioning skills. Because of that, this research has a purpose to find out the effect of implementing the Problem Based Learning (PBL) model based on Technological Pedagogical and Content Knowledge (TPACK) on students questioning skills. This research used a quantitative approach with a quasi experimental method and a non- equivalent control group design. The subjects of this research are 70 grade XI students in MAN 2 Samarinda, including class XI-B as the experimental class and class XI-A as the control class. The instruments used in this research are interviewing the teacher, observing the learning activities, and an assessment rubric of students questioning skills. The results of this research showed that students questioning skills in the experimental class increased significantly compared to the control class, as shown by the Mann-Whitney U test with a significance value of 0.015 < 0.05. The number of questions from students in the experimental class was more varied (20 questions) compared to the control class, which had fewer questions (5 questions). The conclusion is that the implementation of the TPACK based Problem Based Learning (PBL) model has a positive effect on students questioning skills in the cell material of Grade XI.

Abstract

The average biology learning outcomes of eleventh-grade students at MA Negeri 1 Samarinda are still below the Minimum Completion Criteria (KKM), while innovative learning models such as POE (Predict-Observe-Explain) have never been implemented. Biology learning has been mostly based on lectures, discussions, assignments, and practicums, while scientific attitude assessments are only taken from daily life and practicum activities. This condition requires the implementation of a model that can actively involve students to encourage scientific attitudes and science process skills (SPS). This study aims to determine the effect of the POE model on the scientific attitudes and SPS of eleventh-grade students on the sensory system material. The method used is a quasi-experimental design with a Nonequivalent Control Group Design, involving class XI-F as the experiment and XI-D as the control. The research instruments are scientific attitude questionnaires and SPS tests. The results of the analysis show significant differences between the experimental and control classes in scientific attitudes (p < 0.05) and SPS (p < 0.05 with the Mann Whitney U test). Improvements in scientific attitudes were demonstrated by an N-gain of 0.35 (moderate) in the experimental class and 0.19 (low) in the control class. Meanwhile, the N-gain of the Student-Based Learning (KPS) reached 0.60 (moderate) in the experimental class and 0.29 (low) in the control class. The conclusion of this study is that the POE model effectively improves the scientific attitudes and science process skills of eleventh-grade students at MA Negeri 1 Samarinda.

Abstract

Seventh-grade students of SMP Negeri 37 Samarinda face problems in science learning, namely not achieving learning mastery. The learning process is still dominated by conventional teacher-centered methods that cause students to tend to be passive and learning media are less varied, so that learning activities are not effective. To overcome these problems, this study applies the Problem Based Learning (PBL) learning model assisted by LKPD Liveworksheets which encourages students to think critically and actively to be able to solve problems thoroughly and completely. This study aims to determine the effect of the problem based learning model assisted by LKPD Liveworksheets on the learning outcomes of seventh-grade students in science subjects at SMP Negeri 37 Samarinda. The type of research used is quantitative research with a quasi-experimental method using a non-equivalent control group design. The research sample was selected by purposive sampling consisting of classes VIIC and VIID with a total of 44 students. Data analysis was carried out using the independent sample t test and the N-Gain test. Based on the data analysis, the t-test obtained a significance value of 0.004 (p < 0.05), indicating a significant difference between the learning outcomes of students in the experimental and control classes. Furthermore, the N-Gain analysis showed that the experimental class obtained a score of 0.63, which is in the moderate category, while the control class obtained a score of 0.57, also in the moderate category. These findings indicate that the implementation of the Problem-Based Learning (PBL) model assisted by Student Worksheets (LKPD) based on liveworksheets has a positive impact on improving student learning outcomes in Natural Science (IPA) for seventh graders at SMP Negeri 37 Samarinda.
