Practicality of Life Skills-based Student Worksheets to Improve Critical Thinking in Respiratory System Material of Senior High School
Abstract and Figures
This study aims to determine the practicality of life skill based student worksheets (LKPD) of class XI of high school on respiratory system material. The method used in the study was a research and development. The data source of this research was from two science teachers and thirty one students of class XI. The LKPD practicalities data was obtained through questionnaires practicalities of the device which was given to teachers and students.The analysis of the data used descriptive analysis that is to categorize the average score on learning process. Based on the analysis of the data, practicality of LKPD through three assessment data, it showed that the first observation data with anaverage 97,4 % in a good category, the second dataquestionnaire responses of teachers with an average 95 % in a good category, and the third data questionnaire responses of students with an average 91% in a good category. Based on the analysis of the data, the practicality of the student worksheets has an average with the excellent category for all aspects. This shows that life skill based worksheet can be used as a biology learning medium in high material school.

Penelitian ini bertujuan untuk mengetahui perbedaan keterampilan berpikir kritis siswa melalui pembelajaran konvensional dan penggunaan media laboratorium laboratorium virtual pada konsep sistem pernapasan manusia. Metode yang digunakan adalah metode eksperimen dengan rancangan pretest-postest control group design. Sampel penelitian adalah siswa kelas XI semester dua berjumlah 50 orang siswa SMA yaitu 25 orang kelas XI.A dan 25 orang kelas XI.B di SMA Negeri Unggul Sigli Kabupaten Pidie. Pembelajaran di kelas eksperimen dilakukan dengan menggunakan media (software) virtual lab, sedangkan kelas kontrol diterapkan pembelajaran konvensional dan masing-masing kelas digunakan model Pembelajaran Langsung. Efektifitas penerapan Laboratorium virtual terhadap keterampilan berpikir kritis dianalisis dengan menggunakan tes berupa uraian yang dilakukan dengan uji-t (Independent Samples t-Test). Hasil penelitian menunjukkan bahwa thit. 5,507 > ttab. 2,011. Dengan demikian, terdapat perbedaan yang signifikan penerapan pembelajaran dengan menggunakan media laboratorium virtual terhadap keterampilan berpikir kritis siswa pada konsep sistem pernapasan manusia.

This research aims to determine the differences in critical thinking skills of students who taking conventional learning and virtual labs on the concept of the human breathing system. The method used is an experimental method by design pretest-posttest control group design. The research population is high school students at class XI in the second semester of school time. Two classes with 25 students each were chosen purposively for experiment and control class. The experimental classed was taught by using learning media of virtual laboratory software, while the control class was taught with conventional learning and both classes were applied the Direct Instruction Model. Pretest and posttest on critical thinking skills and cognitive learning outcomes of the students in both classes were compared and analyzed by using a test; essay and multiple-choice performed with t-test (Independent Samples t-Test). The results showed that there was significant improvement of critical thinking skills (tcount 5, 507 > ttable 2,011) students that learned through media of virtual laboratory software. Thus, there is a significant difference in the application of virtual laboratory software on students' critical thinking skills on the concept of the human breathing system.

Tujuan penelitian ini adalah untuk mengetahui: perbedaan kemampuan berpikir kritis siswa setelah pembelajaran antara penerapan berbasis masalah dengan pembelajaran konvensional. Penelitian ini dilakukan di SMA Negeri 4 Bireuen. Metode penelitian adalah metode eksperimen. Sampel pada penelitian ini adalah sebanyak 2 kelas yang ditentukan secara cluster random sampling terdiri dari kelas kelas eksperimen (pembelajaran berbasis masalah) dan kelas sebagai kelas kontrol (pembelajaran konvensional). Teknik analisis data dilakukan dengan uji-t. Kesimpulan penelitian ini terdapat perbedaan kemampuan berpikir kritis secara signifikan antara siswa yang mengikuti pembelajaran melalui pendekatan pembelajaran berbasis masalah dengan pembelajaran konvensional. Kata Kunci: Pembelajaran Berbasis Masalah, Berpikir Kritis, Sistem Pernapasan Manusia This research aimed at knowing the difference of students’critical thinking ability after learning process by using problem-based learning and conventional learning. This is done at SMAN 4 Bireuen. This research used experimental method. The sample of the research was 2 classess determined by cluster random sampling. The data were analyzed by using t-test. The result showed that there was significant different of students’ critical thinking ability between the students taught by using problem-based learning and students taught by using conventional learning.

Background: The guided inquiry strategy is a set of learning activities that involves maximally all students' ability to search and investigate systematically, critically, logically, analytically, so that they are able to solve their own problems confidently. Based on the experience of researchers during the KKM in SMA Negeri 12 Ambon, it can be seen that most students have difficulty in biology learning process. It is commonly seen from very low student scores or not achieving KKM standards in the respiratory system material, whereas KKM specified in biology subjects especially class XI is 70. This is due to the teacher-centered learning process, where teachers who provide materials and students who heard. For that, researchers want to use guided inquiry strategy in this learning process, especially the concept of human respiratory system. Method: This type of research is qualitative with the aim to see the cognitive learning outcomes of the human respiratory system of the students of grade XI IPA of SMA Negeri 12 Ambon using Guided Inquiry strategy. This research was conducted in class XI SMA Negeri 12 Ambon District Nusaniwe Ambon city. The research procedure consists of several stages, namely: 1) Planning stage and 2) stage of research implementation. Before doing teaching and learning activities, researchers provide motivation to students about the respiratory system in humans. Then do a preliminary test to determine the initial ability of students. Students are divided into 5 groups and each group must fill the LKS already prepared by the researcher. Then the researchers began to apply guided inquiry strategy. Result: increasing number of students who get KKM 70 score in Biology subject, this is proven by the classification of mastery. Before the learning process (PBM), as many as 31 students of learning outcomes are not complete or get value under the KKM. After the teaching and learning activities are conducted by using the guided inquiry strategy of students whose learning outcomes are not complete or get the value under the KKM is reduced to 0 students. Conclusion: Learning biology with guided inquiry strategies can improve student learning outcomes XI IPA SMAN 12 Ambon
Education must reflect the values of everyday life, both preservative and progressive. So that educational institutions should merge with real-life values that exist in the environment. For this reason life skill education (life skill) undoubtedly to be applied and applied for students in any educational institutions tingakat. The development of life skills values in various activities in educational institutions both in classroom learning, as well as in extracurricular activities, and in religious activities is expected to foster unyielding spirit with high work ethic, creative independence, innovative in creating works in all Field, so that in the end able to create human resources that qualified for the surrounding community.
This is a development research to produce valid and practice Student Worksheet. This research used 3 steps from 4-D models those are defined, design and development.
