This study describes the results of exploratory learning about local wisdom, namely making ceramics. The purpose of this study was to 1) find out the concepts and physics processes in the manufacture of ceramics 2) to know the learning process of higher order thinking in exploring the physics concepts in the ceramic making process. The main activity of this research is to explore the scientific concepts and processes of ceramic making, using the Type B Higher Order Thinking Learning in Democratic Interaction (HOTL-DI) model. This research begins with conducting observations at the ceramics-making training center in Pulutan Village. . The results of observations of data recording procedures for making ceramics are used as a reference for exploration of scientific concepts and processes. Exploration activities are carried out in 2 stages. The first stage is material exploration. The second stage was an exploration activity by a group of fifth grade physics education students. The results showed the learning process of higher order thinking through exploratory learning, where at the beginning of the exploration activity all students still experienced difficulties, but then their ability to explore objects developed.
Seaweed (Caulerpa sp) is a marine biota whose growth is influenced by physical parameters. The purpose of this study was to analyze the dynamics of daily temporal changes in seawater temperature at several depth points and variations in the velocity and direction of ocean currents. Make simple mathematical modeling of ocean current velocity and daily dynamics of seawater temperature in the seaweed growth zone and outside the seaweed growth area. Temperature measurements are carried out on 4 depth variations using a current meter when the sun illuminates the ocean. Measurement of the velocity and direction of the current is carried out using a current measuring instrument during the full moon. The Fourier function or periodic function determines mathematical modeling. The results showed that the transect measurement of sea temperature for 4 depth variations experienced changes due to the intensity of solar irradiation. During one cycle, the speed and direction of the ocean currents change periodically, with the average flow velocity in the seaweed zone being 7.4 m/min and outside the Lahe region being 18.75 m/min directly to the southwest at seawater flows at high tide and northeast experiencing low tide. The daily temporal change in ocean current velocity for each measurement transect shows the same shape which is modeled according to the Fourier function.
The socioscientific approach is a learning approach that is oriented to the context of science and its relationship to social life in society. Thematic learning about flooding is learning that uses themes in linking several subjects so that it is more effective and meaningful because it provides real experiences for students. The objectives of this study are (1) to develop instructional designs on thematic tasks with teachers and parents or the community as learning materials for students, (2) describe the process of implementing flood thematic tasks, (3) describe students' perceptions of material design and implementation of flood thematic learning, (4) improve the mastery of physics concepts, the relationship of mastery of physics concepts with context, the relationship of mastery of physics concepts with biology and mathematics in learning flood thematic tasks with a socio-scientific approach. This study was designed for students of SMP Negeri 3 Tahuna grade VIIIA. Data analysis methods include quantitative analysis used to describe indicators on research variables, indicator correlation using Spearman level correlation, indicator changes from the initial meeting to the final meeting and qualitative analysis used to describe student attitudes and perceptions of learning design and implementation activities. The results of this study obtained that students were actively involved in the discussion of concepts and their application as well as in observation activities. The achievement of group activities between the concept of physics and the context has a perfect correlation
Physics is one of the subjects taught in high School (SMA) and is a subject that is greatly feared by students, various myths that affect motivation and have an impact on student learning outcomes. Physics learning has been described not only as learning in the form of knowledge transfer but a constructivist process that facilitates students to practice skills, build their own cognitive skills and foster positive attitudes. The purpose of this study was to determine: (1) the improvement of student learning outcomes at SMA Negeri 1 Tondano in class X on business and energy materials using the experimental method. (2) the improvement of science process skills in students of SMA Negeri 1 Tondano class X in the business and energy materials using the experimental method. Using qualitative and quantitative experimental research. Improved learning outcomes and science process skills based on the pretest and posttest were analyzed by statistical t-test using the SPSS program. The results showed that the use of the experimental method can improve student learning outcomes with t count 2.763> 1669 t table, so H0 is rejected and Ha. The use of the experimental method can improve science process skills with t count 5.011, thus t count 5.011> 1.669 t table then 1H0 is rejected. And Hα. Experimental learning methods are worth considering in developing physics learning strategies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
