Abstract

The project presents the application of the stages proposed by Poyla for solving problems in mathematics, which have been adapted in mechanical physic. Critical reading strategies have also been applied resulting in reading physical problems comprehensively. Objectives: To incorporate real problem solving as a teaching strategy in two mechanical physics courses (one experimental and another traditional), in order to characterize the group that applies the problem-solving strategy. To validate the problem-solving strategy in mechanical physics. Methods: Mixed research including analysis and contrast of results obtained from two control groups: one experimental (24 university students of Mechanical Physics) and another traditional (16 university students of Mechanical Physics). The control group approaches the study of the subjects in a traditional way where the problems proposed are solved intuitively and somehow mechanically. The experimental group solves the proposed problems by applying each of the stages of the proposed sequence. The experimental group solves the proposed problems by applying each of the stages of the proposed sequence. This study differs from previous studies in that most are related to problem-solving in mathematics and in this case, we focus on physics with the value of involving elements related to critical reading, which gives a more realistic look of the Physical phenomenon studied from the interpretation of its occurrence and how it impacts the environment, which favors its theoretical understanding and gives meaning to its mathematical modeling.

Abstract

The purpose of this study is to determine the effect of Inquiry learning with scaffolding to decrease the percentage of light material misconception among fourth-grade students. The method used was Quasi-experimental with a non-equivalent control group design. The population was fourth-grade students of the Surya Buana Islamic Elementary School, Malang. The result of Anacova showed that for the “Class” variable, the value of Significance (P-value) obtained was smaller than the α significance level of 0,006 < 0,05. Based on the results of the Anacova test it was concluded that there was a significant effect from the use of Inquiry learning with scaffolding to decrease the percentage of light material misconception in fourth-grade students of Surya Buana Islamic Elementary School, Malang. The average percentage of students’ misconceptions in the experimental class at the initial conception was 38.7% and dropped to 15.4% in conception after inquiry learning with scaffolding. While the average percentage of students’ misconceptions of control class at the initial conception was 37.8% and dropped became 22.7% at conception after conventional learning. The decrease in the percentage of students’ misconceptions of the experimental class was greater than the control class by a difference of 10.7%. Further research is suggested to examine more deeply the effect of inquiry learning with scaffolding on process skill, learning achievement, and other aspects of learning that are likely to be developed in students.

Abstract

Ex-mining pond water is widely used for the daily needs of the people these days, such as bathing, washing, and even drinking. Over time, it turns out that coal mine acid water has polluted the environment. The use of membrane technology to produce water that meets drinking water quality standards by the Minister of Health Regulation No. 492 of 2010 can be a solution to this problem. The NF270 membrane is a membrane process between reverse osmosis and ultrafiltration, which has a lower flux and operating pressure below 0.2-1.53 Mpa compared to reverse osmosis. Membrane NF270 is used for the reclamation of wastewater, water purification and softening, seawater desalination, and others. Its high rejection of organic molecules with a molecular weight of 200-2000 Da ions and multivalent can remove suspended solids, natural organic matter, bacteria, viruses, salts, and divalent ions contained in water, including coal mine acid water. The purpose of treating acid mine drainage with the NF270 membrane is to remove COD, TSS, TDS, and Fe metals. The NF270 membrane was used in this study to treat the coal mine acid water of PT. Bukit Asam. The performance of the NF270 process was assessed from the effect of pressure (4, 5, and 6 bar) on the flux and rejection rate of each parameter in a single solution, mixed and aqueous coal mine acid solution. The optimum pressure of the NF270 membrane for all parameters was 6 bar. This optimum pressure was then used to compare the phenomenon of flux that occurred and the level of rejection produced in the original sample of coal mine acid water. In the original coal mine acid water, there was a significant decrease in flux due to fouling deposition on the membrane surface. This phenomenon of decreasing flux was caused by fouling and polarization concentration. The rejection rates produced for the parameters of COD, TSS, TDS, and Fe with NF270 membranes were 56.4-93.1%; 78.5-100%; 43-69.3%; 67-100% respectively. Treated coal mine acid water using NF270 membrane technology can be used as drinking water that meets the standards of the Indonesian Ministry of Health Regulation. Thus, NF270 membrane technology can be used to process coal mine acid water into environmentally friendly drinking water.

Abstract

This study aims to examine the existence of learning material related to educational issues regarding low-carbon levels. Through the content analysis, 26 primary school science textbooks from ten publishers in Indonesia were reviewed, focusing on the study covering the selection, presentation, provision of supporting materials, and low-carbon issues. The research method used is the qualitative content analysis process method with research steps: 1) Data collection; 2) Data analysis textbook; and 3) Ethical considerations. The results showed that sixty one point six percent of teachers said the book was under the curriculum's coverage. The sixty point six percent of the relevance of content to student experiences was appropriate, so is the fifty three point five percent of the relevance of examples and exercises with learning objectives and the material presented. It is also found that fifty five point six percent of various questions and discussions were adequate for testing students, the other fifty one point five percent had included supporting questions and exercises, and sixty point six percent of teachers said there was a teacher's guide. Then fifty point five percent, according to the teacher, students' awareness of low carbon is still relatively low, and forty six point six percent of the content coverage regarding low carbon is still considered sufficient by the teacher. This study concludes that there was too little coverage of low-carbon issues and a lack of additional material related to the low-carbon content in primary science textbooks. The topic of low carbon is still implicit in the environmental literacy found in textbooks. The follow-up that can be done is providing a low-carbon concept to science textbooks in primary schools so that our students and society will have low-carbon awareness and increased environmental literacy.

Abstract

The purpose of this research is to analyze the changes in learning between learning before using the STEAM method and learning after using the STEAM method. Where the researchers analyzed the process of student activities in learning, namely in the course of making learning media to determine the ability of students to think creatively in developing the students' knowledge. In obtaining research data, researchers used an assessment score reference instrument, where the final product assessment was assessed by subject lecturers, learning media expert lecturers, and linguistics (language) lecturers. To find out whether there is a change in the ability to think creatively in each learning process before and after learning, the researcher uses a hypothesis test using the t-test. To find out whether there is a change in ability positively, namely the ability to think creatively in each learning process before and after learning, the researcher uses a hypothesis test using the t-test to find out this. It can be seen from the increase in the average learning outcomes before and after with an increase in the difference of 2.26 from the average before using the STEAM method in learning, which is 78.26. The results of the analysis test explain that the learning method using STEAM in learning has a positive impact on learning where students experience a significant average increase before and after being given learning using the STEAM method by providing hands-on experience through the project work process.

Abstract

This study expects to discover the improvement of science teachers' comprehension of the STEM concept, the improvement of teachers' readiness in implementing it, and the relationship between the comprehension of STEM concepts and readiness in implementing it in learning science. The participants were 50 science teachers from a few junior high schools in Ciamis who joined the workshop and simulated natural science learning dependent on STEM concepts in the Galuh University in Ciamis, Indonesia. The method of study used descriptive utilizing instruments of questionnaires and interview guide. The data were investigated using descriptive statistics with SPSS version 25.0. In addition, data from interviews were analyzed qualitatively (as complementary data). The exploration results show an increase in understanding of the STEM concept of science teachers and an increase in teacher readiness to implement it in science learning. This increase in understanding of STEM concepts and readiness to implement them is strengthened by developing a plan for implementing STEM-based learning and observing STEM-based science learning simulation activities conducted by several workshop participants. In addition, there is also a high correlation between understanding the STEM concept and the teacher's readiness to implement it in science learning.

Abstract

Students’ increasing lack of interest in science has led to a disturbing situation that compels us to continue researching educational motivation, in this line, and within the framework provided by self-determination and achievement goal theories. The great importance of this variable can be attributed to its relevance in classes and its competence-related nature, which in principle makes it a motivating resource, as is the case with science textbooks. In particular, this study provides an in-depth understanding of motivation using various motivational predictors, while incorporating the motivational competence relevance of science books. One thousand students between the ages of 10 and 14 years participated. The research instrument used was a questionnaire consisting of 4 scales that measured the motivational competence relevance of science books, the task-oriented motivational climate, the basic psychological need for competence and the intrinsic motivation. Data were analyzed using correlation analysis and a structural equations model. The results showed that, among other aspects, motivation is influenced by competence, while competence is influenced by the task climate and the motivational competence relevance of science books. These findings suggest that in order to increase students’ intrinsic motivation, teachers must create a task-oriented climate, emphasize the value that student should attribute to science books from a motivational competence perspective, and satisfy the need for competence.
