Abstract

Abstract Lack of conceptual comprehension can lead students to form a wrong concept. Students’ conceptual comprehension that is different from the actual concept is called a misconception. Biological topic that is prone to misconception is cell bioprocess because the topic is abstract and complete. This research aims to describe the profile of students’ misconceptions using the three-tier diagnostic test, to describe the factors that cause misconceptions, and to offer solutions that overcome students’ misconceptions in cell bioprocess topic. The data collection methods were carried out by providing a three-tier diagnostic test through google form and interviewing through google meet and social media. The research subjects were 60 students of the 11th grade MIPA in SMA Negeri 1 Kamal. The data of diagnostic test were processed and grouped according to the category of students’ conceptual comprehension, besides the interviews data were analyzed by generalizations based on interviews’ answers. The results showed that 76% misconception occurred in cell bioprocess with 79.40% misconception in membrane transport, 74.30% misconception in protein synthesis, and 71.80% misconception in cell reproduction. Factors that cause misconceptions are students' low mastery of the concepts, the use of complicated terms and incomplete information in textbooks, also the lack of interaction between teachers and students. Students’ misconceptions can be reduced through the application of interactive models or media that assist in constructing conceptual comprehension correctly. Further studies of the development and implementation of digital-based learning media in cell bioprocess topic including membrane transport, cell reproduction, and protein synthesis sub-topic should be done near the future to reduce students’ misconceptions. Keywords: misconception, cell bioprocess, three-tier diagnostic test

Abstract

Science literacy is very closely related to the era of the Industrial Revolution 4.0 which demands graduates of quality, able to compete globally and master the development of technology-based on information literacy. The quality of teaching materials such as books needs to be improved and developed in line with advances in information and communication technology. One effort that can be done to develop learning resources in the form of printed books is to package them in the form of electronic books. The purpose of this research was to develop an electronic book on Immune system materials to upskill students’ scientific literacy. This research was constructed as a development study using the 4D model (Define, Design, Develop, and Disseminate) but in this research we didn’t include a Disseminate step. Development stage was held in Biology Department of FMIPA Universitas Negeri Surabaya which produced Immune System e-book. Then, the developed electronic book was being assessed by two validators based on its construction requirements, technical requirements, and didactic requirements which include the scientific literacy aspects. Meanwhile the readability assessed by Fry Graphs. This Immune System e-book have 4 features, wish that it will help the students understanding and upskill the students scientific literacy. The results of the e-book’s validity based on its construction requirements, technical requirements, and didactic requirements were 3.9, 4, and 3.75 respectively. These results are categorized as valid and the e-book can be used in class without any significant revision. The readability assessments showed that the passages are suited for 9th‑grade, 10th grade, and 13th grade students. Even though the results are all in a difficult reading category which suits for high school students, revision needed to be done so that the passage in the e-book will specifically suits for 11th grade students.

Abstract

ANALYSIS OF STUDENT SCIENCE PROCESS SKILLS THROUGH ECOLOGICAL PRACTICUMS AbstractThe study aims to analyze students' science process skills in ecology practical activities. The research subjects were 37 students. Data is collected through performance appraisals. The results showed that the science process skills of students were of high category. The score of observing activity skills was 11.49, formulating a problem of 10.59, identifying variables by 10.81, and making conclusions of 10.02. The skills scores for formulating hypotheses are high (10.47), but low in defining aspects of operational variables (6.19), designing experiments (6.53), and analyzing data/information (6.64). Based on these findings, it can be concluded that the ecology practicum activities that have been carried out can improve the science process skills of prospective teacher students in the aspects of observing, formulating problem formulations, identifying variables, and compiling inferences. Based on these findings, several recommendations are stated, first; Science process skills (SPS) must be taught continuously to biology majors because they are a major part of the education curriculum. Also, it must focus more on integrated skills. Second, pay attention to low SPS student teacher candidates' still exists, so it needs to be trained intensively in the low SPS because the SPS (defining operational variables, designing experiments, and analyzing data) is an SPS that is closely related to knowledge formation and problem solving.

Skor keterampilan untuk merumuskan hipotesis berkategori tinggi (10,47), tetapi rendah pada aspek mendefinisikan operasional variabel (6.19), mendesain eksperimen (6.53), dan menganalisis data/informasi (6.64). Berdasarkan temuan ini dapat disimpulkan kegiatan praktikum ekologi yang telah dilaksanakan dapat meningkatkan keterampilan proses sains mahasiswa calon guru pada aspek mengamati, menyusun rumusan masalah, mengidentifikasi variabel, dan menyusun inferensi. Selain itu juga, berdasarkan temuan ini dapat dinyatakan beberapa rekomendasi, pertama; keterampilan proses sains harus diajarkan secara terus-menerus untuk para guru jurusan biologi karena itu adalah bagian utama dari kurikulum pendidikan. Selain itu, harus lebih fokus pada keterampilan terintegrasi. Kedua; memperhatikan masih adanya KPS mahasiswa calon guru yang rendah, sehingga perlu dilatihkan secara intensif pada KPS yang rendah tersebut, karena KPS tersebut (mendefinisikan operasional variabel, mendesain eksperimen, dan menganalisis data), karena KPS tersebut merupakan KPS yang berkaitan erat dengan pembentukan pengetahuan dan penyelesaian masalah.
