Now, the whole world is facing the coronavirus pandemic. In the meantime, students in China are required to do social distancing and not go to school. This coronavirus pandemic resulted in the use of online learning to teach students. In this research, we will get to know the students’ learning attitude towards online learning during the coronavirus pandemic. The sample population for this research are students in West Java, Indonesia. The data will be collected by using questionnaires and there was a total of 16 questionnaires that is collected for this research. The result of this research shows that online learning during this coronavirus pandemic is not very effective. Also, the students’ learning interest towards online learning is also very low. Based on the interview done on students and teachers, most of them stated that there are various factors that can affect online learning in China such as learning environment, internet and etc. The suggestion that is given in this research is that aside from online classes, teachers can also use video learning media that are used by developed countries so that it can solve the bad internet problem. The result of this research hopefully, can become a reference to improving a more effective learning media that can be used during the coronavirus pandemic in Indonesia.

This study aims to develop interactive multimedia learning media on science subjects using Adobe Flash as a learning media for SD IVC classes. This development is in the form of learning media products in an interactive CD. The method used in this study uses the Research and Development (R & D) method with a 4D model that has 4 stages of development, namely define, design, development, and desseminate. The results of the validation test show that interactive multimedia learning media in science subjects are declared good with the results of validation by media experts 3.75 with very valid categories, expert material 3.5 with very valid categories, and by 3.54 users in good categories. Based on the N-Gain of 0.60 with the medium category and it can be said that the effectiveness of interactive multimedia as a learning media is classified as effective. Based on these results, it can be concluded that the development of interactive multimedia on science subjects using adobe flash as an instructional media for SD IVC is declared feasible and effective to be used in the learning and teaching process.

One of the strengths of the RADEC learning model is that learning focuses on teaching and problem-solving skills, so in other words, RADEC is a learning model that can develop students’ Higher Order Thinking Skills (HOTS). Learning steps of RADEC consisted of 5 steps which were very easy to remember because they were in accordance with the name of the learning model itself, namely: (1) Read; (2) Answer (A); (3) Discuss (D); (4) Explane (Explain) and (5) Creat (C). At each step of learning RADEC, it can develop HOTS. Students must be able to explore and engage in the learning process so that students’ higher-order thinking skills can be honed. In RADEC learning, each stage can develop high-level student skills including the step of Read. HOTS can be learned in this step by giving the widest opportunity for students to explore and find information from various sources both print and internet. The step of Answer, HOTS can be taught by asking students to look for various alternative answers and solutions. In the Discuss Stage, HOTS can be taught by not limiting students in submitting guesses, ideas, or opinions. The Explane Stage, HOTS can be taught by presenting and communicating the results of the agreement group answers honestly and responsibly, and the other groups will respond to it. While the last stage was Creat, in this step, HOTS can be taught by asking students to provide solutions with their creativity. The results showed that there was an increase in students’ HOTS from an average of 41 to 84.6 after learning with the RADEC learning model.

The case study reported in the paper investigated the effect of Project-based learning on students training to be mathematics teachers, pursuing their final projects. The final projects had as an aim of designing attractive and interactive mathematics learning material. This study used a qualitative method to assess the impact on the trainee teachers in terms of their creative design thinking. The research made use of the Hawgent dynamic mathematics software package. The study participants were all students at Guangxi Normal University, China. The students were divided into three groups, each with four or five members. The results presented show that selecting material and combining it with art using dynamic mathematics software can improve the communication skills, problem-solving and creative thinking skills, and improve the prospective teachers' self-confidence. Moreover, it was found that prospective mathematics teachers need motivation and support during their projects' lifecycle and that motivation has a positive effect on improving self-confidence.

This research is motivated by the low involvement of students in learning. This study aims to determine the differences in the learning outcomes of science students between the experimental class and the control class by applying the learning model VAK. This study uses quasi-experimental methods with a nonequivalent control group design. This research was conducted in 147 Public Elementary Schools Pekanbaru with class IV D as the experimental class and class IV A as the control class. Based on the results of the study, it can be seen from the experimental class pretest score of 51.25 and posttest which is 80.63. In the control class the average score of the pretest was 45.53 and posttest was 72.89.The score of the average gain of experimental class science learning outcomes is 0.62 and the average score of the control class is 0.50. The results of the t-test gain score average thitung >  ttabel or 2,89966 > 1,99547 then Ha is accepted. Based on the results of the t gain test between the experimental class and the control class there were differences in learning outcomes IPA student learning in class IVSD Negeri 147 Pekanbaru which are significant.
