Paruman The Khemion Master: Learning Chemistry Periodic table with Trading Card game

The purpose of this research is to learn about how IP character can help students remembering their lesson. In this case we apply the research to a subject that majority students having difficulty to learn, it is chemistry. Some students say that chemistry is the hardest subject for them. Some say that the hardest part is to remember codes and elements on chemistry. Even they said it is the most boring subject, and usually they get a bad mark for it. Based on our survey, we find out that most of students having difficulties to study the subject using traditional method. They prefer to learn using graphics, because it is easier to remember the codes. For this case, we create a set of play card that can help students remembering the chemicals codes. Each card has a unique IP Character that resembles chemical element. Writers also add an element, which could make the chemistry lesson easier to understand, that is game. A game rule will be applied on the card game, and it will help student learned chemistry. And to make it more attractive and fun, we also try to put some technology to the game. Using a technology called Augment Reality, we try to engage students more.

Bibliometric Analysis of The Term ‘Cooperative Learning Chemistry’

Bibliometric analysis related to cooperative learning methods is a new theme and has never been studied. The research pattern related to cooperative learning methods is still uncharted and it is not known how effective it is when analyzed from several previous studies. Cooperative learning chemistry concepts provide suitable solutions for improving activity of students and chemistry learning outcomes. This study aims to demonstrate an all-compassing bibliometric analysis in the terms and concepts of ‘cooperative learning’. The articles evaluated were identified through Google Scholar database as well as the perish or publish software. Furthermore, scimagojr.com (Q1, Q2, Q3, and Q4) was adopted during scanning, and a total of 19 articles were analyzed from 7 reliable journals. This research using literature review method. The type of research used a bibliometric review in five measures method pioneered. These five steps describe the keyword of the search as cooperative learning chemistry, initial search results, improvement of these results, collection of initial data statistics and data analysis, as explained below. The results showed the practice of cooperative learning in chemistry is being widely accepted. However, there is a need for further research and Collaborations on inter-regional studies involving Asian scholars and developed nations in particular regions. The results showed that more than 75% of cooperative learning has a significant effect on learning outcomes. The learning model is an external factor that affects learning outcomes.

Effectiveness and Utilization of Field Trip as a Method of Teaching and Learning Chemistry in Senior Secondary Schools in a Council Area of Imo State, Nigeria

The study assessed the effectiveness and utilization of field trip as a method of teaching and learning chemistry at senior secondary schools in Owerri Municipal Council Area of Imo State, Nigeria. The population of the study was all the 4664 chemistry students in the government-owned secondary schools in the Council. Simple random sampling technique was used to select five schools and 20% of the numbers of chemistry students in each of the sampled schools were used to obtain the sample size of 288 chemistry students. Four research questions were posed for the study. The research was descriptive survey design and questionnaires were used to elicit relevant data while mean rating was used for the analyses of the data obtained for the study. The results gave grand means of 3.14, 1.70, 3.51 and 3.21 for research questions 1, 2, 3 and 4 respectively. These findings showed that field trip is interactive, motivating and provides opportunity for chemistry students to widen their practical knowledge of industrial application of chemistry; chemistry teachers do not utilize field trip in teaching and learning of chemistry; lack of chemistry and chemical process-based industries, time constraint, transportation cost/risk, and the organizing process are the factors that influence effective utilization of field trip. Based on the findings, it was recommended that school field trips should reinforce the curriculum and they should be arranged at every level of the Department at various times, criterion based set of guidelines for planning and conducting successful field trips should be developed; workshops and seminars should be organized for teachers on the importance of field trip and its utilization in the teaching and learning of chemistry. Again, when considering a field trip, teachers are advised to first consult with their administrator regarding existing school board policies and follow that recommended procedure. School authorities should assist in the provision of funds or transportation for field trips.

Dual Mode Module as New Innovation in Learning Chemistry: Project Based Learning Oriented

<p class="0abstract">Chemistry is branch of science that is different because of chemical representations. The chemical representation made students assumed that chemistry is difficult. Students must master chemical representation to be able understand chemistry deeply. Besides, science process skills are crucial skills in learning chemistry, however, the students’ science process skills are rare to be involved. Chemical representation and science process skills have relationship each other. Nowadays, it was still difficult to find module could be used either face-to-face learning or online learning. Therefore, this study aimed to develop valid module integrated chemical representation and science process skills, and can be used in face-to-face learning and online learning (dual mode module) and to investigate teachers’ response about module. The research design used was ADDIE, data collected by using online validation form that was given to 6 validators to assess module based on suitability content, potential effectiveness, and overall satisfaction. To investigate chemistry teachers’ response to module, the online questionnaire given to teachers and it was further analyzed using percentage and compare to criteria of validity and criteria of response user. Th result found that module developed is valid with suitability content is 90.7%, potential effectiveness is 92%, and overall satisfaction is 92.5%. The chemistry teachers’ response showed that this module is very good criteria (92.36%). Therefore, dual mode module hopefully would be used in learning chemistry as media in face-to-face learning and online learning and also support chemical representation and science process skills among students. </p>
