Published: July 2022

Research has been carried out with a device to observe the phenomenon of Rayleigh Benard convection, made of a glass box bounded by a lower plate and an upper plate. The bottom plate is hotter than the top plate which functions to heat the horizontal fluid layer from below. This study aims to observe the phenomenon of water molecule movement. The observation medium was water mixed with teak sawdust as a representation of water particles with an average density of mean=0.99 g/cm3. The variation of water thickness (d) used 5 cm and 6 cm with variations in temperature difference (DT) with an average increase of 50°C. Data was collected with a cellphone camera and run with Windows Movie Maker software which has a time accuracy of up to 0.001 seconds. It was observed that an increase in the temperature difference (DT) between the two plates resulted in an increase in the velocity of motion of water particles in convection which is depicted by a v-DT diagram. Due to the difference in temperature (DT) also results in the movement patterns of water molecules, namely laminar and turbulent. The turbulent phase with the Rayleigh number value R~107, indicated that the flow of water particles is getting faster, the direction of the flow of the particles starts to become irregular and sometimes signs of a water vortex appear. At different fluid immersion results in the start of a turbulent phase. The turbulent phase for d=5cm is observed at DT~30°C, and d=6cm at DT~20°C. Furthermore, this RBC phenomenon is used as a representation of learning natural phenomena in air fluids, namely whirlwinds as an event due to differences in temperature and pressure of a fluid

Depth of Science Learning Materials in Schools and Student Concept Mastery
Authors: Laelandi Rahayu , Widodo Ari , Sriyati Siti
Published: July 2022

The depth of science material in schools is related to the teacher's ability to master science concepts. A good teacher is a teacher who is able to compile the concept of science material in a planned manner. Such planning is for example compiling material in-depth or broadly, so that later students are able to master the concept optimally. This article aims to analyze the depth of science learning materials and students' conceptual mastery of the material presented by the teacher. Data were obtained by observing the delivery of concepts and duration used by the teacher and students' mastery of concepts from questions in the form of a description of 6 questions. The sample used is a science teacher and 22 students. The results showed that the teacher conveyed the material not in-depth because there were several concepts with incomplete or separate sub-concepts. As a result, students' mastery of concepts is low even though in question number 3 about the concept of the lithosphere, most of the students on average answered correctly and correctly when compared to the answers to other questions. The high mastery of students' concepts is because the sub-concepts conveyed by the teacher are only mentioned and are not explained in-depth, while the low mastery of students' concepts is because there are too many supporting sub-concepts and the concepts are too deep, thus requiring students' critical thinking skills.

In the experimental group, physics learning was oriented to student activities where students dealt with physics objects. In contrast, in the control group, physics was taught conventionally by applying direct learning. The ability to interpret and to make reasoning about data was obtained through written tests conducted on pre-test and post-test. Analysis of research data was carried out by qualitative descriptive and t-test statistical analysis. The descriptive analysis was performed to describe students' abilities to interpret and to make reasoning about data. A statistical t-test analysis was conducted to determine the difference in the impact of treatment on the two groups. The results showed that the average ability to interpret data and to make reasoning about data in the experimental group was 76.91 and 76.99, respectively, while in the control group, it was 53.33 and 63.08, respectively. The results of the t-test analysis showed that the 2-way (t-tailed) significance value was 0.000 < 0.05, so it could be stated that there was a difference in ability between the control group and the experimental group. Based on the results of these studies, it can be noted that learning physics that involves a lot of student activities that interact directly with physics objects can improve the skills of high school students in interpreting and reasoning scientific data.

Learning amid the COVID-19 pandemic underwent significant changes, the implementation of learning which was initially carried out face-to-face at school, became learning from home/belajar dari rumah (BDR). On the other hand, the strategy should make students think at a higher level. Based on observations, it was found that students were still very lacking in understanding physics learning and learning methods that seemed monotonous and boring. So to overcome these problems, the application of a problem based learning model is carried out. This study aims to determine the effect of applying the problem-based learning model in online learning on student learning outcomes in heat material. This type of research is included in the type of quantitative research. The research method used is experimental. Subjects in the study were students of SMP Negeri 6 Gorontalo City in class VII. It consisted of three (3) classes, namely the experimental class, replication 1, and replication 2. The instrument used in this study was a written test (essay) consisting of pre-test and post-test. test. The process of collecting data through written tests in the form of pretest and posttest to see the consistency of the influence of student learning outcomes. The data analysis technique used is the normalized gain test (n-gain), the normality test of the hypothesis test data. The results show that learning by applying the Problem Based Learning model can affect student learning outcomes. This is shown through the hypothesis testing criteria where for the experimental class tcount 7.304 is greater than ttable 2,035, for replication class 1 tcount 8,266 the value is more dominant than ttable 2,037, and for replication class 2 tcount 9,658 is greater than ttable 2,037 so it can be said that the test the hypothesis tcount is more dominant than ttable, this can be interpreted that the Problem Based Learning model is quite influential in student learning outcomes.

The ability of teachers to choose learning strategies is an essential and significant concern. In this case, the use of technology in learning. However, not many teachers still use the old strategy, so it is necessary to test with the application of new strategies in the learning process. The intended application of the new strategy is the application of the flipped classroom learning model. The purpose of this study was to determine the differences in student learning outcomes between classes using the flipped classroom learning model and classes using conventional learning models at SMP N 2 Bolangitang Timur. This study used an experimental method with a pretest-posttest control group design. Samples or subjects were taken using the quota sampling technique, namely class VII A and VII B. The data analysis technique consisted of a normality test, homogeneity test, t-test and n-gain test. The results showed that both data were normally distributed and had a homogeneous variance. The t-test analysis at the significant level (α = 0.05) got the results where t0 = 2.24 ta = 2.02 so that H0 was rejected and H1 was accepted. So it can be concluded that there are differences in student learning outcomes between classes that use the flipped classroom learning model and classes that use conventional learning models at SMP N 2 Bolangitang Timur.
