This study aims to describe the impact of online mentoring activities in implementing the RADEC (Read, Answer, Discuss, Explain, and Create) learning model on the competence of elementary school teachers in training students’ critical thinking skills. The method was a pre-experiment with a one-group pretest-posttest design involving 25 elementary school teachers in Indonesia. The teachers received online mentoring in implementing RADEC learning model. The research instrument was a questionnaire to measure teachers’ knowledge and skills in training critical thinking. The data processing technique was carried out by calculating the mean and the percentage of each item to obtain a description of the teachers’ knowledge and skills in training students’ critical thinking before and after treatment. The data were analyzed inferentially with a paired sample t-test using SPSS version 22 software to see the impact of the treatment on teachers’ competence in training critical thinking. Based on the results of the paired-sample t-test, for both the knowledge and skills aspects, the probability value (sig) was 0.00 <0.05. This result means that there was a significant difference in the knowledge and skills of teachers in training students’ critical thinking skills before and after mentoring activities. The study results indicate that the online mentoring in implementing the RADEC learning model improved teachers’ competence in training elementary school students’ critical thinking skills.

Inquiry-based learning has been tested to improve conceptual understanding, reduce misconceptions, and provide students with experiences in scientific work. However, in its implementation, inquiry-based learning is often faced with scientific facts from the real world with data which hard to analyze using traditional methods. Therefore, a breakthrough is needed to overcome the weaknesses of inquiry-based learning by integrating digital analysis tools and the concept of real-world learning. This integration produces a new learning model, the Digital Analysis Tool-Assisted Real-World Inquiry (Digita-RI). This study aims to test the feasibility and practicality of the Digita-RI learning model. This Research and Development (R&D) use the steps proposed by Barg and Gall. The feasibility test of the Digita-RI model was carried out through the Focus Group Discussion (FGD) method and the assessment of the Digita-RI model book involving seven experts. The practicality test was carried out through the Think Aloud Protocol (TAP), and the assessment of the Digita-RI model guidebook involved five practitioner lecturers and six students. The results of expert, practitioner, and user assessments were analyzed using the Aiken coefficient (Aiken’s V). The results showed that Digita-RI is a feasible and practical learning model. Therefore, it can be concluded that Digita-RI has the feasibility and practicality to be used in science learning in the classroom.

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.

The aim of this research was to determine the attitude towards scientific research in undergraduate university students from Peru and Spain. The research was descriptive, comparative and cross-sectional. The sample consisted of 953 undergraduate students currently enrolled in universities in Spain (485) and Peru (468), and the information was collected through convenience sampling. The General Index of Attitude towards Research instrument was applied, which was adapted for the study. Its statistical validation was carried out and high reliability of the instrument was proved with a Cronbach's Alpha of 921. According to the questionnaire scores, a sociodemographic survey was also applied. Regarding the results, it was found that students from Peru have a high predisposition towards research (51.5%) compared to students from Spain (23.5%). Regarding knowledge about research, students in both countries recognize that scientific research is not adequately valued (60.6% in Spain and 54.3% in Peru); however, they would like to carry out educational scientific research (63.3% and 71.2, respectively). Regarding the evaluation of the quality of university education, undergraduate students from Spain perceive a better quality in their education (7.22 out of 10), quality of the program in which they are enrolled (7.31 out of 10), quality of fellow students (7.46 out of 10), and welfare and infrastructure services (7.30 out of 10). It is concluded that students from Peru show a better attitude towards research (M=28.98, DT=10.26) than students from Spain (M=22.61, DT=8.28).

Evidence has been found that some students seem to have learning obstacles associated with particular sensory preferences when dealing with instructional materials. Therefore, knowing students’ sensory preferences could help teachers improve instructional resources. Our objectives were: (1) to describe Secondary students’ sensory preferences according to gender and age; (2) to analyse the possible association between students’ sensory preferences and their general academic achievement in science. We conducted a synchronic, cross-sectional descriptive study in a sample of 582 male and female students from 7th to 11th grade using the VARK questionnaire. There was a significant predominance of sensory preferences containing the Kinesthetic mode, and the preferences containing the Visual mode were the least frequent. Girls or boys showed similar distributions of sensory preferences. Using linear regression to predict students’ general academic achievement from VARK scores, we obtained a significant contribution of the Kinesthetic score, and a minor but still significant single contribution of the Reading/Writing score.

Efforts to fulfill food security to anticipate population growth in Indonesia need to be supported by universities through research and community service. The application of the Natural Animal Audio Organic Growth System (NA-AOGS) with a STEM (Science, Technology, Engineering, and Mathematics) approach is an effort to help the community increase crop yields and accelerate the growth of soybeans (Glycine max (L.) Merill). The research method used is R&D (Research & Development) which is modified from Cennamo and Kalk (2018). This model is in the form of a spiral cycle using 5 (five) main activities as follows: (1) defining the product conceptual; (2) designing research products; (3) demonstrating the product in a limited trial; (4) developing the product through the process of evaluating the test results, and (5) presenting the product to the public.  The direct impact of learning is the improvement of science process skills and critical thinking of students participating in the Biophysics course at the Natural Sciences Study Program, Universitas Negeri Yogyakarta. This is due to the effective application of STEM to link science learning with contextual technology and engineering (NA-AOGS), environmentally friendly technology (only using natural animal sound frequency variables), mathematical elements in data analysis, and analysis of soybeans plant growth charts. The economic impact of this research is the scientific contribution in the form of adaptation of agricultural technology so that it can increase soybean yields (an increase of 130.38% on an area of 2750 m2). The novelty and contribution of this research is the integration of science learning with agricultural techniques and technology with a STEM approach so that it can improve the welfare of farmers in educational institutions as a new model in science learning.

The statement of teaching philosophy reflects on teachers’ growth and dedication to achieve the goal and values. Concerning philosophy, physics is the most fundamental science discipline which has profound philosophical implications. This article aims to discuss the importance of the teaching philosophy statement (TPS) for sustaining the teaching-learning process in the classroom. Moreover, it also includes the authors’ TPS in teaching physics. This academic paper employs the systematic literature review and narrative literature review to explain scholarly opinion regarding teaching philosophy among physics and natural sciences philosophers. Three educational implications have been discussed. First, educators need to realize that not every student wants to be a physicist, and teachers need to manage this problem. More often, the physics teachers also have to think about addressing students with different abilities in the classroom. Second, as the facilitator of the learning outcomes, the teachers must possess good character and value-laden attributes necessary for teaching. Finally, the researchers of this study provide the TPS for physics, “Let Us Think About,” and philosophical implications in teaching physics. The term of teaching philosophy may vary based on the expert who writes it and its application in the classroom (i.e., philosophy in science teaching, philosophy of physics, philosophy of science in teaching, teaching philosophy, teaching statement, and teaching philosophy statement). However, the teaching philosophy statement is the most common phrase since Beatty et al. explain the concept in the early 21st century. In addition, the finding indicates that TPS is important for developing teachers’ way of thinking in the classroom setting.

This research aims to examine undergraduate students’ argumentation skills during and after the learning process in the classroom setting and their responses toward the implementation of socioscientific issues (SSI) through debate in the learning process. This research involved 32 undergraduate students and implemented design-based research with pretest and posttest in a natural classroom setting using three topics of SSI debate that widely discussed in Indonesia: Nuclear Powerplant (Topic 1), Food Preservation (Topic 2), and Genetically Modified Organism (Topic 3). Data was collected using observation sheets, tests, and questionnaires. Observation is to measure argumentation ability when applying the debate method in class settings, the test measures the improvement of argumentation skills, and questionnaires measure students’ responses to the application of the debate method. In this study, argumentation scores were obtained from six indicators and divided by a maximum score of 24 times 100. Normalized gain (N-gain) was calculated to determine the effectiveness of the intervention in the classroom. T-test was also conducted to test the significance of the differences in the pretest and posttest results on argumentation skills.  The results obtained in this study are: the argumentation skills score during the learning process for six groups were 95, 80.6, 90.3, 95, 83.3, and 77.5; the mean score of pretest and posttest were 52.22 ± 6.62 and 85.78 ± 4.72. The consistency of opinions shows the change from “agree” to “disagree” for Topics 1 and 3. The undergraduate students agree and consistently agree toward Topic 2. The paired t-test result also shows that the intervention statistically has a significant difference between the two means, indicating that the undergraduate students’ argumentation skills are better than before the intervention. Otherwise, most of the undergraduate students respond positively toward the implementation of the debate related to SSI. Despite some limitations, the debate on SSI can improve argumentation skills in classroom settings, especially in science education majors.
