The Development of E-Module of Hydrocarbon Material Using Lectora Inspire

2024-02-16T10:41:08+00:00

Hydrocarbon material is one of the materials in chemistry which is a problem for chemisty education students. In order to develop learning media that makes it easier for students to understand hydrocarbon, research to the development of e-modules is carried out. The goal of this research is to create an e-module of hydrocarbon material that is useful and receives positive feedback. ADDIE model consisted of analysis, design, and development was used as research and development model in this study. In total 12 students from the Chemistry Education Study Program FKIP Untan, and 32 students from the main test served as respondents. Measurement and indirect communication techniques are employed in the investigation. Feasibility evaluation sheets and response questionnaires are the instruments utilized for data collection. The results show that the e-module is highly viable, with a percentage of material feasibility 88%, linguistic feasibility 91%, technical feasibility 92%, and 95% graphic viability. In the initial experiment, the proportion of student questionnaire responses was calculated at 83%, and in the main test, it was calculated at 84%, which was deemed to be very good. E-module of hydrocarbon material using Lectora Inspire was pronouneed to be extremely feasible and received a very good reaction based on the research findings, that it can be used as a learning resource in learning hydrocarbon material to improve students’ understanding.

An Application of Classical Test Theory for Item Characteristic Analysis of Chemical Literacy Instruments

2024-02-16T10:41:04+00:00

The science literacy skills of students in Indonesia are very concerning, the cause is that students are not accustomed to working on questions based on science literacy, so it is necessary to have a standardized assessment instrument based on chemical literacy that can measure the level of achievement of scientific identification and interpret science/chemistry learning. This study aimed to describe the characteristics of chemical literacy-based assessment instrument items of reaction rate material with a classical test theory approach. The type of research is descriptive quantitative. The research subjects were 80 class XI MIPA SMA Negeri 4 Takalar students. Data were analyzed using the ITEMAN 4.3 program. Based on the results of the analysis, a reliability coefficient of 0.834 was obtained, the level of favorability of 87% of the items was in the moderate category, and 13% was in the difficult category. In the difference test, as many as 73% of the items are in the very good category, and for the distractor test, 93% of all items have shown distractors that function properly, so it can be concluded that overall the items have high reliability and good item characteristics.

Inquiry-Based E-worksheet with Local Wisdom of Brebes Central Java for High School Students’ Understanding of Reaction Rates

2024-02-16T10:40:59+00:00

Teaching materials play a significant role in facilitating effective learning, particularly when utilizing inquiry-based approaches and incorporating an appreciation of local wisdom. This research has the purpose to create an E-Worksheet based on inquiry and enriched with local wisdom from Brebes, Central Java, specifically designed for the topic of reaction rates. The research method employed is Research and Development (R&D) utilizing a 4D development model. The developed E-Worksheet encompasses six learning activities that align with the guided inquiry model, with support from the Flip PDF Professional program. The quality of the E-Worksheet is evaluated by a variety of experts, such as subject matter experts, media experts, peer reviewers, chemistry teachers, and high school students. The assessment results reveal a high degree of validity, with peer reviewers assigning a rating of 88.56% (Very Good), reviewers evaluating it as 92.05% (Very Practical), and students rating it at 91.37% (Very Good) in terms of readability. Hence, this E-Worksheet is regarded as an effective learning tool in the field of chemistry education, enabling students to actively participate in the learning process while also gaining an appreciation for indigenous knowledge.

This research aimed at describing and explaining the implementation of project-based learning results in Fundamental Chemistry I course. This research was focused in achieving the 21^st century learning target, namely students’ critical thinking, creativity, collaboration, and communication skills. This research was conducted in Chemistry Education Study Program of Undiksha involving 19 people of first year students in academic year 2022/2023. This research was qualitative research using descriptive method. The data were collected by utilizing observation and document analysis techniques and analyzed by using interpretive analysis. The research results reveal that: 1) Students are able to propose project titles critically and creatively in accordance with the given theme; 2) Students are able to plan and implement the project as well as report the project results in accordance with the given format; and 3) Students are able to communicate the project orally and written through classroom presentation and project report writing.

Validity of a Chemistry Learning Module Based on Socio-Scientific Issues

2024-02-16T10:40:51+00:00

This paper aims to determine the validity and eligibility percentage of socio-scientific issues-based chemistry learning module by material and media experts. The method used in this research was Research and Development (R&D) using the 4D model by Thiagarajan. The module was validated by two material experts and two media experts. The instrument used to obtain the validation data was an expert assessment questionnaire. The data were analyzed using quantitative descriptive analysis techniques. The validation value by material experts was 57.5, and its eligibility can be categorized as ’very good’. The percentage of eligibility from the material expert assessment obtained was 89.84%. The validation value by media experts was 61.50, and its eligibility can be categorized as ’very good’. The percentage of eligibility from the media expert assessment obtained was 96.09%.
