Abstract

The purpose of this study is to determine the electron’s position expectation values and energy spectrum on the Li2+ ion on the principal quantum number n≤3. This research using literature study methods on quantum mechanics. The expectation values of the electron position and the energy spectrum of the Li2+ ion uses numerical calculations using the Matlab 2019a program. The steps in this research method include: preparation; theory development; simulation; validation of the results of theory development; results of theory development; discussion and conclusion. The results obtained in this study are the electron’s position expectation values and energy of the Lithium ion. The electron’s position expectation values indicates the presence of electrons that often appear around the x-axis by relying on the interval used. The larger the interval, the more constant the electron’s position expectation values will be and towards an almost constant value. From the analysis results, the expectation value varies in positions from  0,0001a0 to 0,1637a0. The electron energy spectrum of the Li2+ ion is inversely proportional to the square of the principal quantum number (n),E1= -122,4 eV ; E2= -30,6 eV ; E3= -13,6 eV

Abstract

Abstraction is the primary key in computational thinking. This study aims to analyze students’ computational thinking skills of abstraction on the concept of kinematics. The data were collected through students’ project documents and interviews. The data is examined using a content analysis approach that emphasizes writing, verbal, or visual communication. The results revealed that students’ abstraction skills were evident in collecting data and analyzing, and recognizing patterns but were less visible in building models or simulations. Abstraction skills can be used as a foundation and framework for viewing a concept in physics not only in mathematics or formulas views but as a data iterative relationship. This research is expected to provide an overview for physics instructors to integrate computational thinking in their learning classroom

Abstract

Education needs to emphasize more attention to environmental issues. The school is an active place to provide actual knowledge, skills, attitudes, and behavior towards environmental issues such as global warming dan the greenhouse effect. This study aimed to investigate seventh-grade students' cognition in the context of a climate system. This study was descriptive, involving the collection of qualitative data. These qualitative data were then analyzed for their content inductively to identify concepts and patterns of student responses. This study indicated that students believed that global warming caused by six factors involving the greenhouse effect, depletion of the ozone layer, fossil fuel usage, forest fires, use of chemicals, and industrial air pollution. Also, they convinced six segments of the global warming impacts: ocean, soil, air, plants and animals, humans, and weather and season changes. The student thought about the climate system was substantially linear, where the contribution of human activities caused global warming that finally have an impact on humans themselves.

Abstract

This study aims at investigating the Physics students' thought patterns concern-ing the greenhouse effect. Descriptive analysis was used, including the set of qualitative data. These data were then interpreted for their idea and content inductively to recognize students' thoughts and models concerning the greenhouse effect. The result confirmed three patterns of the students' thoughts concerning the greenhouse effect (patterns A, B, and C). The model covered different concepts, mechanisms, and processes of the greenhouse effect. The students' knowledge from science teacher explanations and books is not the only learning source concerning the educational environment. The issue and broadcast media frequently carry out confusing the concepts. This research is expected to provide physics teachers critical information to develop appropriate teaching methods and strategies concerning these topics.

Abstract

Indonesia is an agricultural country so there are still many agricultural environments. One of the implementations of the agricultural sector in education, it’s can be applied to vocational high schools agriculture major. Students learning activities in this major can be integrated with their practical activities in the agricultural sphere, because learning physics will be more attractive to students if the learning activities in the classroom also linked with students daily experience and environment. Within the scope of agriculture, agricultural tools are closely related to the concept of physics, one of which is the hoe. So the purpose of this research is to describe the physics concepts analysis on the use of hoe by farmers, then designed a draft of physics learning materials. This research is descriptive qualitative research using content analysis method to obtain the results that in the use of hoe there are several physics concepts about mechanics including the concept of force, rotational dynamics, work and energy. Then processed into a draft of physics learning materials for students of vocational high school class X in agribusiness and agrotechnology major, by adjusting the relevant basic competencies, namely KD 3.4 on work and energy, and KD 3.6 on rotational dynamics.
