4C skills have become part of the current elementary school curriculum, which is expected to improve the quality of education so that graduates are ready to compete in the global world. Student worksheet, based on the RADEC model, is needed as a learning tool that can help participants practice 4C skills. This study aims to develop and validate the Student Worksheet based on the RADEC model on the theme of aerial skills-oriented 21st century: critical thinking, collaboration, creativity, and communication (4C). This research and development (R&D) use the ADDIE model (Analyze, Design, Develop, Implement, Evaluate). This research was carried out until the development stage or validation stage. The validity of the student worksheet is determined by an assessment of media, materials, and language on a scale of four, validated by twenty-five teachers who have attended the RADEC model workshop for three days. The data obtained were tabulated by calculating the validity of the quantitative and descriptive analysis. The development results show that the student worksheet based on the RADEC model to train 4C skills is declared valid with the calculation results Vh>Vt or Vh> 0.64 and is suitable for use in learning. This research can be used as information on the development and validation of teaching materials, especially student worksheet, based on the RADEC model to train 4C skills in science materials in elementary schools.
The nature of science is essential to be conveyed in the curriculum and student books because it becomes a reference in the learning process to adequately achieve learning objectives. This study aims to describe aspects of the nature of science in the "merdeka" curriculum and its comparison between countries and an analysis of the nature of science in elementary science books. The quantitative descriptive method is carried out by studying literature and analyzing documents on aspects of the nature of science in the "merdeka" curriculum documents and elementary science books. Curricula documents from other countries are analyzed to find out the comparison. Based on the analysis and comparison results, it is shown that the nature of science in the elementary school curriculum and its embodiment in student books is not explained explicitly, both in the curriculum and in student books. The percentage of science essence values in the student curriculum is > 80.00%, namely product, subjective, and creative aspects, and in student books, only product aspects have a percentage value of > 80.00%. It is known that the percentage of the emergence of the nature of science is different in each country.
To develop students’ 21st century skills, it is necessary to develop STEM-based worksheet to provide learning that links knowledge and technology with contexts in everyday life so as to create learning that is able to prepare students to compete in the future. The main focus of this research is the development of a feasible STEM-based worksheet in science education in elementary school. This research is a Design and Development study with the ADDIE model which consists of the analysis, design, development, implementation and evaluation stages. Based on the analysis of the curriculum, needs, and the learning environment of students, STEM-based worksheet is developed. The worksheet was assessed for its feasibility by experts and teachers. In addition, user parents/guardians and students are given response assessments. The evaluation of experts and teacher practitioners shows that the teaching material is considered very suitable for use .
