Abstract

The basis of the research was that misconceptions greatly affect student learning outcomes because they can understand and interpret a concept incorrectly. Students who have understood the concept can be measured from good learning outcomes. Low learning outcomes identify difficulties in the student learning process, thereby affecting the level of student understanding. The research conducted was descriptive research. The facts found from the research results were then described in accordance with the actual situation in the form of data. The data obtained was then processed, interpreted, recorded and analyzed using statistical data. In this study, researchers collected data regarding a symptom that occurs as a result of the learning process. The source of the data in this study was obtained by administering a three tier multiple choice diagnostic tests to a predetermined sample. Based on the data obtained in items 1, 7, 11 of the 18 items it is said that the highest misconception is because students cannot explain the characteristics of a solid substance correctly. Judging from these problems, students experienced misconceptions of reasoning or incomplete or incorrect reasoning. Based on the results of data analysis and discussion, it can be concluded as follows: There is a misconception about the concept of substances and their characteristics. The percentage of misconceptions about the concept of substances and their characteristics is 30%. The percentage of false negative misconceptions on the concept of substances and their characteristics is 8%.

Abstract

Various human activities have caused the concentration of greenhouse gases (GHG) such as CO2, CH4, and N2O in the earth's atmosphere to increase, which has an impact on increasing global temperatures and has led to the climate crisis. To reduce GHG emissions, countries that ratified the Paris Agreement set targets to be achieved as Nationally Determined Contributions (NDC). The Paris Agreement must be integrated into diplomatic practice as climate diplomacy. The method used in this research is qualitative-descriptive analysis. The data used were reports from the Intergovernmental Panel on Climate Change (IPCC) and Indonesia's contribution to the NDC document. The research results showed that 1) Global warming had caused a climate crisis so that it has become a threat to the survival of life; 2) Indonesia's contribution in reducing the rate of global warming through NDC had not been able to reach the target of 29% with its own efforts or 41% with assistance and cooperation; and 3) Climate diplomacy, which is expected as an effort to reduce the climate crisis, was not easy to carry out. The obstacle to implementing climate diplomacy is that each country has its own interests.

Abstract

This research aimed to (1) know the influence of implementing the practicum-based CTL model in learning on the cognitive learning outcomes of students studying colloids in class XI SMA Swasta Bersama Berastagi (2) determine the correlation between affective scores and student learning outcomes in the application of the CTL model based on colloid subject matter practicum for class XI SMA Swasta Bersama Berastagi; (3) determine the correlation between psychomotor scores and student learning outcomes in the application of the CTL model based on colloid subject matter practicum for class XI SMA Swasta Bersama Berastagi. The research used a pretest-posttest control group design. Based on research that has been carried out, the average score obtained by experimental class students in the initial test (pretest) was 59 and the final test (posttest) was 86.13. The average score of experimental class students at the beginning (pretest) was 53.92 and the final test (posttest) was 75.25. Student learning outcomes using learning models Contextual Teaching and Learning Practicum Based experienced an increase of 67% in the medium category. This increase can be proven by the results of the hypothesis test which obtained tcount > ttable, namely 5.58 > 1.72, which proves that student learning outcomes by applying the CTL model based on class XI colloid practicum subject matter are not the same as student learning outcomes who apply the conventional model.

Abstract

This research was motivated by the low ability of students to apply mathematical solution methods to thermodynamic functions. Thermodynamic functions are functions that consist of pressure, temperature, volume and enthalpy functions where changes in one function can occur due to changes in other functions. The aim of this research was to show the implementation of chain rules in thermodynamic function problems by relying on a process technique to improve students' cognitive awareness of thermodynamic functions. The place of this research was at the TD Pardede Institute of Science and Technology. The process of understanding chain rules is very impactful for understanding thermodynamic state functions. Differential decomposition of functions within functions is also described in the chain rule method. Thermodynamic functions which consist of pressure, temperature, volume and enthalpy functions can depend on each other so that the chain rule analysis method can be clearly used. With this method students will also be given the opportunity to connect one concept with other thermodynamic concepts. Apart from that, this method can be used anywhere. This shows a cognitive increase in terms of cognitive elements, cognitive structure and cognitive function.
