Description of Learningg Outcomes, Misconceptions, and Inhibitory Materials, and Their Relationship With The Implementation of The Scientific Approach Aslamiah Al Anshori; Zonalia Fitriza
Entalpi Pendidikan Kimia Vol 3 No 2 (2022)
Publisher : Universitas Negeri Padang

The 2013 curriculum requires the application of scientific approach in learning. As many as 53.84% of the 13 chemistry teachers in West Sumatra experienced difficulties in implementing scientific approach cause the limited time allocation and low student learning outcomes.This study aims to describe learning outcomes, misconceptions, and inhibitory materials and the relationship between the implementation of the scientific approach to the chemical bonding material. This descriptive research uses Mixed Method with Convergent mixed parallel design. The population is the students of X class SMA in Pasaman Regency with sample of class X MIPA. Data were collected using document analysis, observation methods, and tests. The data were analyzed using the Miles & Huberman analysis technique, normality test, and correlation test. The results of this study indicate that the scientific approach has not been implemented properly. Student learning outcomes <4% and as many as 61 types of misconceptions were identified cause the presence of inhibitory materials such as atomic stability for chemical bonds, PEI and PEB for molecular geometry, and Lewis structures for intermolecular interactions. The results of the analysis concluded that there was a correlation between the implementation of the scientific approach and learning outcomes with a significance of 0.00 and a correlation coefficient of 0.617. So, the implementation of the scientific approach affects student learning outcomes.

Thermochemistry is one of the chemistry learning materials that is difficult for students to understand, so it requires a level of chemical representation in the learning process which is assisted by the presentation of interactive powerpoint media. This study aims to produce an interactive powerpoint learning media based on guided inquiry that is suitable for use for learning and can determine the level of validity of the interactive powerpoint learning media. The type of research used is Research and Development (R&D) with a 4D development model. The research instrument used was a validity questionnaire which was processed using the Aiken's V formula.

Validity and Practicality of Flipped Classroom Based on Guided Inquiry on Reaction Rate Material Aprilia Ninda; Mawardi Mawardi
Entalpi Pendidikan Kimia Vol 3 No 2 (2022)
Publisher : Universitas Negeri Padang

Indonesia is entering the era of the industrial revolution 4.0 which is marked by advances in the field of technology. Teachers are required to have the ability to integrate technology into the learning process. In addition, the reaction rate material is classified as a material that is difficult to understand because the material is abstract. For that we need an appropriate learning system. Then a guided inquiry-based flipped classroom learning system was developed using Moodle on the reaction rate material. The type of research conducted is educational design research (EDR) with a plomp development model. Based on the research conducted, it was found that the level of content and media validity of the flipped classroom learning system based on guided inquiry was 0.89 and 0.93 with valid categories. While the level of practicality of teachers and students is 0.90% and 0.91% with a very practical category.

Description of Student Chemistry Learning Difficulties in Acid Base Material Class XI IPA at SMAN 7 Padang Maryana Dwi Atika; Latisma Latisma
Entalpi Pendidikan Kimia Vol 3 No 3 (2022)
Publisher : Universitas Negeri Padang

Acid base material is a material that is quiet difficult to understand, because 75,5% of class XI science students at SMAN 7 Padang hae not been able to achieve the learning KKM that has been set. This is an indicator that there are still many student who have learning difficulties. Learning difficulties are inability of students to learn to achieve learning objectives and are characterized by low learning outcomes. This research is a descriptive research that aims to describe the level of learning difficulties of students and the factors that influence it in each indicator learning of acid base matter. The subject of this research is class XI IPA 6 SMAN 7 Padang TA 2021/2022 students who number 38 people. The instruments used are two-tier multiple choice diagnostic tests, questionnaire sheets and interviews. Data processing uses descriptive statistical methods. From the results of this research it was obtained that students have difficulty learning in acid base matter. Students' highest learning difficulties lie in the first indicator of analyzing soluble properties based on acid-base theory according to Arrhenius, Bronsted-Lowry, and Lewis by 77.2% with a high category of learning difficulty levels. Based on the results of questionnaires and interviews with students, the factors that cause students' learning difficulties in acid-base materials are seen from the internal factors of students are due to the student's less effective way of learning, namely not concentrating, not making schedules and carrying them out, not repeating materials, not taking notes and reading, and not doing assignments.

The Amine is closely related to everyday life, especially the caracteristic and sampling. This subject is a part of the carbon compounds taught on the second semester of 3rd grade High School. But the implementation was transferred to first semester due to the student’s final exam, so the learning process was uneffective.Therefore it needs 2013’s curriculum compatible teaching materials as amine students woeksheet which help students study independently. The purposes of this research are to develop a Problem Based Learning Student Worksheet and determine its validity. The research implementation uses the R&D method. The development stage uses a 4D model consisting of define, design, develop and disseminate which is limited to development due to time and cost limitationsThe data collection technique was carried out by distributing questionnaires. The research data by five expert validators were analysed using the Aiken’s V formula. Based on the a research data obtained the resulting a validity of 0,87 with a valid category.

The material of molecular shape or geometry is chemical material that has abstract properties, resulting in students having difficulty understanding the material. Therefore we need a learning media that is able to help students understand the material and able to display modeling in the form of animations, videos and pictures of molecular shapes clearly. PowerPoint-iSpring ia a learning media that is able to display animations, videos, texts, images and quizzes that can help students understand the concept of learning materials correctly. This research aims to develop a valid PowerPoint-iSpring learning media on the material of molecular shapes in class X SMA. This research uses the Plomp model which was carried out until the prototype III stage (expert review and one to one evaluation). The validation of this learning media was carried out by 5 validators, 3 chemistry lecturers at FMIPA UNP and 2 chemistry teachers. The assessment was carried out on the content, contructs and media of the developed PowerPoint-iSpring learning media. The result of conten validity is 0,87. Construct validity is divided into 2 components, linguistic and presentationd components with average values of 0,83 and 0,86. While the validity of the media on the components of the media efficiency, button function and physical quality are 0,93:0,95 and 0,8. So that the result of the validity of content, constructs and media can be categorized as valid.
