The development of programming skills is currently promoting from an early school age, trying to get children to take an active and creative role in the use of technologies. The objective of this article is to verify the repercussion of educational robotics activities on kindergarten students in the acquisition of computational thinking and programming skills. The research design is quasi-experimental, with pre-test and post-test measures, using experimental and control groups. The sample consists of 131 students from the second cycle of early education (between 3 and 6 years old), all from the same Spanish school. Computational thinking is measured through three dimensions: sequences (algorithms), action-instruction correspondence and debugging. The intervention sessions, as well as the structure of the challenges that were used in the pre- and post-test evaluations, were designed based on the reference program of robotics studies called “TangibleK”. The intervention, carried out doing learning activities using educational robotics resources, presents positive results in relation to the computational thinking skills achieved. The differences between the pre-test and the post-test in the experimental and control groups are statistically significant, in that children engaged in robotics program achieves a greater advance in the three dimensions of computational competence through this method. Actualmente se promueve el desarrollo de habilidades de programación desde una edad escolar temprana, tratando de que los niños adquieran un rol activo y creativo en el uso de las tecnologías. El objetivo de este trabajo es comprobar la repercusión del desarrollo de actividades de robótica educativa en la adquisición de habilidades de pensamiento computacional y programación en escolares de educación infantil. El diseño de la investigación es de tipo cuasi-experimental, con medidas pretest y postest, utilizando grupo experimental y control. La muestra la conforman 131 estudiantes del segundo ciclo de educación infantil (entre 3 y 6 años de edad) de un centro educativo español. El pensamiento computacional se mide a través de tres dimensiones: secuencias (algoritmos), correspondencia acción-instrucción y depuración.

Data Analysis Result

Vocabulary is the basic aspect of language. The ability to master vocabulary holds an important part in learning a language, including English. That becomes one of the researcher's considerations to conduct this research when observing at one of Indonesia's high schools since the students show difficulties in vocabulary mastery. Modifying the teaching media can become a problem solving for students' lack of vocabulary mastery. In this case, using Rosetta Stone CALL software is suggested to overcome the problem. The research's objective was to determine whether or not the use of Rosetta Stone CALL software can improve the tenth-grade students' vocabulary mastery. The researcher applied a quasi-experimental method, with two group pre-test and post-test design. The research sample was forty students from two classes taken from the population of the 10th-grade students of SMA Negeri 2 Barru. The data analysis result showed that the pre-test's mean score in the experimental class was 2.21, and the post-test was 3.04. It proves that the tenth-grade students' vocabulary mastery improved using Rosetta Stone CALL Software. After analyzing the data using SPSS version 21, the probability value in the post-test was 0.01, and the significance value was 0.05. It means that the probability value (0.01) was lower than the significance value (0.05). It was indicated that H0 was rejected and H1 was accepted. It revealed that the vocabulary mastery of the tenth-grade students of SMA Negeri 2 Barru for the experimental and control groups was significantly different.

Robotics is needed as education keeps up with challenges students are facing in a technological environment. A long-term research project focuses on developing a feasible robotics-based learning environment that enables primary school teachers to introduce computer science education. This paper shows educational robotics combining storytelling to promote computational thinking through the method of Tell, Draw, and Code. The study was conducted via pre–post test, using the Beginners Computational Thinking test (BCTt), with third and fourth graders (N = 40) to determine if the integration of robotics-based storytelling activities enhances computational thinking skills. Results show that an increase in computational thinking is evident after the intervention is implemented. The approach of combining stories, texts, and literature with educational robotics seems to be a promising concept to equip students with the required skills.

Electrochemistry is difficult to learn due to its abstract concepts involving macroscopic, microscopic, and symbolic representation levels. Studies have shown that students can visualize and improve their understanding of chemistry by using interactive computer animation and simulation. This study reports the effect of interactive computer animation and simulation module named “Interactive Electrolysis of Aqueous Solution” (IEAS) developed to aid students in learning electrolysis. A pre and post-test control quasi-experimental design was carried out to investigate the effects of the IEAS on students’ achievement and motivation in electrochemistry topics. This study involved 62 16-years-old male students from two different secondary schools. Pre and post electrochemistry achievement tests (EAT) and pre and post- Instructional Material Motivation Surveys (IMMS) were used. For EAT, using one-way ANOVA, it shows that there was a significant difference in the post-test mean score in this study on the understanding of the electrolysis concept between students in the treatment and control groups [F (1, 60) = 5.15, p <0.05]. The qualitative results also provided evidence that the students in the treatment group had a better conceptual understanding than the control group, especially at the microscopic representation level. For the IMMS test, there was a significant difference between the treatment and control groups in terms of the mean score of the post motivation IMMS test where p <0.05 in chemistry learning [F (1,59) = 266.89, p <0.05].  Thus, it can be concluded that IEAS has an impact on enhancing the students’ understanding of the electrolysis concept, and the students are more motivated to learn electrochemistry.

Landslides as a natural disaster often occur due to the movement of landmasses. Lack of community preparedness in facing disasters is one of the significant risk factors for catastrophe. This study aimed to determine the effectiveness of education using WhatsApp on community preparedness to face landslides. This research is a quasi-experimental study with a pre-post test design with a control group. The number of samples was 30 people taken by simple random and divided into treatment and control groups. The treatment group was given educational intervention with WAG media (WhatsApp Group), while the control group was assigned a P2P (Picture to Picture) intervention. Preparedness data in the form of knowledge and attitudes were analyzed using the Mann-Whitney test. The results showed that statistically, there was no difference in preparedness to face landslides through WAG or P2P. However, there was an increase in readiness through knowledge and attitudes in both groups. Education about landslide preparedness through WAG or P2P has the same effect in increasing public knowledge and perspectives. The information received through WAG or P2P will ultimately influence a person's experience and attitudes regarding landslide disaster preparedness.
