Prototype Phase

Implementation of the 2013 curriculum has generally used recommended models, but the role of the work-sheets used in the learning process still does not facilitate students' critical thinking skills. The research aims to evaluate the validity, practicality, and effectiveness of the development worksheets on the microbial concepts based on urban wetlands to improve students' critical thinking skills. The development of work-sheets was carried out in 2 phases; preliminary research phase and prototype phase using the Tessmer design. Content validation uses a validation assessment sheet instrument. The practicality data of the contents was using an assessment sheet instrument on the worksheet structure. Practicality data (expectations and actual) were collected using a practicality sheet instrument obtained from students' responses to the contents of the worksheet. Effectiveness data (expectations and actual) are obtained based on the results of critical thinking skills, interpersonal skills (cooperation), and intra-personal skills (responsible). Data analysis techniques by calculating the percentage of validation refer to Akbar (2017), practicality test, and effectiveness test with criteria referring to Purwanto (2012). The results showed that worksheets for students were valid and were practical for users with the practicality of contents and practicality of expectations is good. Work-sheets was declared to be effectively used based on the results of the critical thinking skills, interpersonal skills (collaboration), and intra-personal skills (meticulous), and the value of the effectiveness of expectations is good categories too.

Abstract: The purpose of this research is to make the learning device based on guided inquiry in science learning and affectivities to improve students’ critical thinking skills and to examine its validity, effectiveness, and practicability. This research adapts Borg & Gall Research and Development and modification. The instruments of the research were instrument validation results, practicality, and effectiveness. Data were collected by employing a validation sheet that was validated by the assessor to gain validation and practicality scores, the student's positive response questionnaire and learning result test sheet were full filled-in by the students, and the observation sheet was full filled-in by the observer. The average score of total validity is in the score range of 2.6<SV≤3.5 and is an invalid category. The result of practicality research of learning devices based on practicality questionnaire the range of 3.5-4.0 and is in a very practice category. The result of effectiveness based on learning result test showed that 75 % of the students are completely based on the results of the research, it can be concluded that the learning device based on guided inquiry is valid, practical, and effective that is feasible to be used in a learning activity in the classroom.Keywords: Development Research; Guided Inquiry; Critical Thinking Skill

Initial Research

Students' critical thinking skills are still not optimal. One of the reasons is the use of teaching materials in the form of student worksheets that are not yet in line with the good student worksheet structure, do not yet contain the STEM approach, and critical thinking indicators have not been clearly illustrated in the student worksheet. The purpose of this study is to determine the validity of the LKPD, determine the practicality and effectiveness of using student worksheet Physics based on the STEM approach that can improve students' critical thinking. This type of research is research and development (R&D) using the Borg & Gall model which consists of the initial research and information gathering stage, planning, developing the initial product format, and initial trials. As the object of research is the Physics student worksheet based on the STEM approach. Data collection instruments used were expert validation sheets, practicality test sheets, and effectiveness test sheets. The effectiveness test uses an assessment sheet of learning outcomes tests and observation sheets of students' critical thinking. The data analysis technique used is the analysis of the validity of the Physics student worksheet, the practicality analysis of the use of the Physics student worksheet, and the effectiveness analysis of the use of the Physics student worksheet. Based on the analysis of the data that has been done, two research results can be put forward. First, the average value of the validity of the Physics student worksheet based on the STEM approach is 0.88 and this value is included in the valid category. Second, the average value of the practicality test for the use of Physics student worksheet by teachers and students respectively 91.44 and 84.14. This value shows the Physics student worksheet is in the category of very practical. Besides that, the use of Physics student worksheet based on the STEM approach is effective to improve students' critical thinking

The Impact

The role of education is to improve the quality of education, especially in producing high-quality students. High-quality students are those who are able to think critically, creatively, logically and take initiatives in responding to issues in society caused by the impact of the development of science and technology. This study aims to determine the effect of a scientific approach to students' critical thinking skills. This study is an experimental research with one group pretest-posttest design. The sample of this study consisted of one class (28 students), which was treated using a scientific approach. Critical thinking skills are measured using a test instrument and then analyzed statistically (t test). Hypothesis test results indicate that there is an effect of using a scientific approach toward students' critical thinking skills.

This study aimed to determine the effectiveness of Guided Inquiry-based Student Worksheets on Archimedes’ Law. This study used an experimental method with a research design of one group pretest-posttest design. The population in this study was all students of class XI MIA Public Senior High School 1 Sariwangi, the research sample was XI MIA 2. The sampling technique was done by using cluster random sampling. The data collection instrument used a pretest and posttest assessment sheet. Data analysis used statistical tests, namely N-Gain and t-test. The test result of the effectiveness of student worksheets based on guided inquiry using N-Gain analysis obtained a value of 0.97 with high criteria. Furthermore, the result of the t-test showed 15tcount&gt;t(0,995)(30)">  that it was 4.15>2.75. This indicated that there was a significant difference between the pretest and posttest scores. Based on the average N-Gain and t-test, it can be concluded that guided inquiry-based student worksheets are very effective in improving students' critical thinking skills. The results of this study have the implication that guided inquiry-based student worksheets can be used in the implementation of learning as a form of assistance for students to improve students' critical thinking skills.

Tacit Assumptions

The contemporary demands of the education environment today require that teachers refine their reflective thinking skills and shift towards the deeper critical thinking skills inherent in reflexive thinking. Reflexivity is a deeper level of critical thinking that assumes a degree of metacognition and “knowing-in-action” (Schon, 1983, p. 50). Metacognition is a critical tool in helping individuals become more aware of their deeply seeded biases and tacit assumptions about the way the world works. Through a phenomenological analysis of four individual case studies, this study found that student feedback was a key catalyst for building reflexivity skills. Specifically, the study details the key ways by which feedback prompted novice teachers to metacognitively think through their knowing-in-action and ultimately improve their teaching practice. The research details important implications in three areas: 1) practice, 2) theory, and 3) future research.
