Critical thinking skills are one of the rational thinking skills that students really need in solving problems or conveying ideas. In fact, students' critical thinking abilities are still relatively low. A feasible alternative for developing students' critical thinking skills is by implementing electronic-based scaffolding.
This research uses mixed methods with an explanatory research design. The experimental group received conceptual treatment of e-scaffolding blended learning with the Problem-Based Learning model and the control group received no additional treatment. experimental group and control group, the research subjects were first semester students of IKIP Budi Utomo Malang. Because there were two research groups, 46 students were included in the control group. The instruments used in this research were pre-test and post-test. The pre-test consists of 18 multiple choice items with a reliability coefficient of 0.735 and the critical thinking post-test consists of 14 essay questions with a reliability coefficient of 0.762. In addition, semi-structured and think aloud interview guidelines were also used. Quantitative data was obtained from the distribution of pre-test and post-test questions. Meanwhile, qualitative data was obtained from semi-structured interviews and think aloud. Quantitative data was then analyzed using parametric ANACOVA analysis while qualitative data was analyzed using a path analysis model.
The results of the research show 1) the critical thinking abilities of students who learn with conceptual e-scaffolding in blended learning in Problem-Based Learning are higher than students who learn with conventional methods, 2) the application of conceptual e-scaffolding in Problem-Based Learning. The link map form in the Problem Based Learning model has a positive effect on students' critical thinking abilities. This is reflected in the behavior and way of thinking of experimental group students which shows the development of critical thinking skills during the learning process. Apart from that, conceptual e-scaffolding in the form of a link map helps students obtain information easily and use it in understanding concepts in geometric optics material

Critical thinking ability is one of the rational thinking capabilities that is highly required by students in solving problems or delivering an idea. In fact, however, students’ critical thinking skill is still categorized as low according to the previous studies. One feasible alternative to be done in developing students’ critical thinking ability is implementing electronic-based scaffolding. For that reason, there should be research to examine conceptual e-scaffolding in blended learning on Problem-Based Learning (PBL) model to observe the first semester students’ critical thinking ability at IKIP Budi Utomo Malang.
This study employed mixed-methods with explanatory research design. The experimental group was given conceptual e-scaffolding treatment in blended learning on Problem-Based Learning model and the control group did not receive any additional treatment. For both experimental and control groups, the research subject was the students in the first semester at IKIP Budi Utomo Malang. As there were two research groups, 46 students belonged to the control group. The instruments utilized in this research were pre-test and post-test. The pre-test consisted of 18 multiple choice items with reliability coefficient of 0.735 and critical thinking post-test consisted of 14 essay question items with reliability coefficient of 0.762. In addition, semi-structured interview and think aloud guidelines were used. Quantitative data were obtained from the distribution of pre-test and post-test items. Meanwhile, qualitative data were retrieved from semi-structured interview and think aloud. The quantitative data were then analyzed using ANACOVA parametric analysis while the qualitative data were analyzed using path analysis model.
The research findings indicated that: 1) the critical thinking ability of students who studied with conceptual e-scaffolding in blended learning on Problem-Based Learning was higher than those who studied with conventional method, 2) the implementation of conceptual e-scaffolding in the form of link map in Problem-Based Learning model influenced positively towards students’ critical thinking ability. This was reflected from the behavior and the way of thinking of students belonged to the experimental group indicating critical thinking ability development during the learning process. Furthermore, conceptual e-scaffolding in the form of link map helped the students to obtain information easily and utilized it in understanding concepts in geometrical optic material
