It is important to improve teachers' pedagogic competence continuously. This study aims to investigate the impact of the workshop about the implementation of the Read-Answer-Discuss-Explain-And Create (RADEC) learning model on elementary school teachers' pedagogical competence to implement the RADEC learning model. This descriptive research involved 16 teachers from 8 elementary schools in Tasikmalaya City. All participants received workshop materials including 21st century skills, RADEC learning model, and practices to prepare, conduct and evaluate RADEC learning model implementation. The research instruments were questionnaire and observation sheets. Research data were processed quantitatively and qualitatively. The results show that after participating in the workshop many teachers can plan (86.1%), implement (83.3%) and evaluate (58.3%) RADEC learning model. The results of this study also show that most of the teachers (97.2%) are interested in implementing the learning model in their schools because the model is easy to understand and its implementation can help students to gain attitudes, knowledge, and various 21st century skills (critical thinking and problem solving, collaboration, communication and creative thinking). The results of this study indicate that the workshop about implementation of Read-Answer-Discuss-Explain-And Create (RADEC) learning model can improve elementary school teachers' pedagogic competence.

This study investigated the impact of socialization and workshops about the Read- Answer-Discuss-Explain-and Create (RADEC) learning model on teacher readiness to implement it. The investigation involved 92 teachers (elementary school, middle school, and high school teachers). The research instrument was a questionnaire consisting of two parts. The first part questionnaire was given before the activity and was intended to reveal the experience of the teachers to implement currently familiar innovative learning models. The second part questionnaire was given after the activity and was intended to reveal the teachers' readiness to implement the RADEC learning model. Data were processed quantitatively and qualitatively. The research results of the first questionnaire show that teachers had not been able to implement currently familiar innovative learning models for various reasons. The research results of the second indicate that the social- ization and workshop can prepare teachers to implement the RADEC learning model. This can be seen from the majority of those who argue that (1) the syntax of the RADEC learning model is easy to remember and understand; (2) the RADEC learning model can practice 21st century skills; and (3) they are interested in researching the implementation of the RADEC learning model.

Learning science is not just memorize the concepts, but learn how to process and mastery of the scientific attitude. Actually, learning is still centered on the teacher, so that students can develop the knowledge and skills of thinking. Knowledge and thinking skills students can experience a change in the proper way, one way that can be done by applying the model of project-based learning. This study aims to determine whether there is a difference mastery of concepts and creative thinking skills between classes that implement learning model project based learning and classroom rather than project-based learning on water recycling materials. The research design used in this study was Quasi Experimental Design devoted no pattern Nonequivalent Control Group Design This design consists of two groups: the experimental group and the control group. Furthermore, each class were given a pretest and posttest study with mastery test questions using the concept of multiple choice questions of 15 questions and test creative thinking skills with five essay questions on each test. Classroom learning experiment treated with a model project based learning and classroom learning with no control got projet models based learning. The results showed in general there are significant differences in mastery of concepts (p = 0.00) between the experimental class learning by applying the model of project-based learning in the learning process (the average N-gain = 0.477) in the medium category, with students learning by applying rather than project-based learning (the average N-gain = 0.290) in the low category. There is no difference in the ability to think creatively (p = 0.22) between the experimental class and control class, with an average N-gain the experimental class 0,075 while the control class is 0.060 which both are in the low category.

The purpose of writing this article was  to describe RADEC learning model in building critical thinking skills. This study was  conducted because of the need for a learning model that fits the Indonesian context to build critical thinking skills that can be used at  elementary school level. This study used the literature review. This study produced  one solution to be able to build critical thinking skills using  RADEC learning model (read-answer-discuss-explain and create). The approach in learning  done by the teacher plays a role in improving critical thinking skills. The teacher needs to use a learning model that can stimulate students' critical thinking skills.

ABSTRAK Keterampilan berpikir tingkat tinggi bagi siswa sekolah dasar sangat penting untuk menghadapi abad 21. Salah satu model pembelajaran yang dapat dikembangkan adalah RADEC (Read-Answer-Discuss-Explain and Create). Tujuan penelitian ini adalah untuk mengetahui pengaruh model pembelajaran RADEC terhadap keterampilan berpikir tingkat tinggi siswa kelas V sekolah dasar pada tema ekosistem. Metode penelitian yang digunakan adalah kuasi eksperimen dengan the matching pretest-posttest design. Sampel ditentukan secara purposive, dengan siswa SDN 5 Pagarsih sebagai kelas eksperimen dan SDN 1 Pagarsih sebagai kelas kontrol. Instrumen yang dikembangkan mengacu taksonomi Bloom Revisi. Hasil penelitian menunjukkan model pembelajaran RADEC memiliki pengaruh positif terhadap berpikir tingkat tinggi siswa dibandingkan dengan model pembelajaran inquiri. Hal tersebut diperhatikan dari skor rata-rata pretest di kelas RADEC 40,44 dan inquiri 38.14. Sementara skor rata-rata posttest kelas RADEC 70.08 dan inquiri 56.5. Data tersebut menunjukkan bahwa peningkatan pada kelas eksperimen mencapai 29.64, kelas kontrol 18.36. Sintaks pembelajaran RADEC sesuai dengan konteks keIndonesiaan, khususnya pada tahap Read dan Answer yang membuat siswa lebih siap untuk belajar. Selanjutnya  Discuss, Explain dan Create yang lebih efektif dan  memudahkan proses pembelajaran.  Simpulan penelitian ini adalah model pembelajaran RADEC lebih berpengaruh positif dibandingkan model pembelajaran inquiri terhadap ketrampilan berfikir tingkat tinggi siswa.  Kata kunci: Keterampilan Berfikir Tingkat Tinggi, RADEC, Sekolah Dasar ABSTRACT Higher order thinking skills for elementary school students are important to face the 21 century resulting on RADEC (Read-Answer-Discuss-Explain and Create). The purpose of this research was to determine the effect of the RADEC learning model on HOTS of fifth grade elementary school students on the ecosystems theme. The research employed quasi-experimental model with the matching pretest-posttest design. Furthermore, the instrument developed refers to Revised Bloom's taxonomy. The results showed positive effect on students' higher order thinking compared to inquiry learning models seen from the average pretest score in the RADEC class 40.44 and 38.14 in the inquiry class, while the average posttest score in the RADEC class is scored 70.08 and 56.5 in the inquiry class. The data indicated that the increase in the experimental class reached 29.64, while the control class scored 18.36. The syntax used in RADEC learning model is in accordance with the Indonesian context, especially in the Read and Answer stages which make students ready to learn. Then, the Discuss, Explain and Create stages are more effective and ease the learning process. The conclusion of this research was that the RADEC learning model has a more positive effect than the inquiry learning model on higher order thinking skills Keyword: Higher Level Thinking Skills, RADEC, Elementary School
