“…Students generally Students procedurally illustrated the processes involved per organelle and provided keywords to simplify the content in their flowcharts. In the study of (Sikumbang et al, 2019), pre-service biology teachers' cognitive structure in biology were investigated and according to the findings of this study, it was concluded that use of flowchart in presenting cellular processes significantly helped the students in understanding biological processes of the cell including cell packaging, protein synthesis, and cell transport. In Module 8, table 4 shows how the students utilized Venn diagrams and with some variations added like flowcharts.…”

Teaching and Learning Biology requires a lot of memorizations of concepts, principles, and laws which may be one of the reasons why students find this area of knowledge highly conceptual. This action research is conducted to improve the teaching practice of Cell and Molecular Biology by investigating and exploring the mental models of students in learning this course under the program, Bachelor of Secondary Education (BSED) Major in Science. This study utilized an action research design by developing learning modules that contain asynchronous tasks which allowed students to design their own concept maps and other visual organizers to explain highly technical concepts in Cell and Molecular Biology. This targets to improve students’ critical thinking and enhance comprehension of difficult concepts which were assessed through summative assessments. Based on the results of this study, the students frequently used concept maps and bubble topical organizers or clusters of objects that show linkages among the topics that were discussed in the modules. Students relatively agreed that use of concept mapping helped them organize their ideas in the entire course of cell and molecular biology. This study recommends the testing of this intervention to other disciplines in science education such as in genetics & biotechnology and in anatomy and physiology to establish the consistency of results.

“…Sejalan dengan itu, Tibell & Rundgren (2010) menyatakan bahwa ilmu biologi molekuler yang merupakan trend bioteknologi modern merupakan konten yang kompleks dan berbasis pada beragam ilmu sains murni seperti matematika, fisika dan kimia serta sains terapan seperti kedokteran dan pertanian. Korelasi dari faktor tersebut menyebabkan kurangnya pemahaman mahasiswa dan adanya miskonsepsi mengenai materi biologi molekuler dan bioteknologi (Sikumbang et al, 2019).…”

This descriptive quantitative study was done purposively on 42 students who have completed the biotechnology lectures in Biology Education Program, Universitas Negeri Malang. The data collection instruments consisted of a biotechnology topic difficulty survey questionnaire and a felt needs questionnaire. The questionnaire response data analyzed using descriptive statistics showed that students perceived the laboratory activity of basic molecular biology techniques as a moderate level. On average, all students performed DNA analysis techniques, and only 55% of all students performed protein analysis techniques. Overall, students have feelings, understanding, and confidence at a moderate level, while they feel they have excellent learning assistance. Even so, students feel they need learning resources in the form of research-based multimedia to support learning on the topic of practicum on molecular biology analysis techniques, especially in protein analysis techniques. Research-based protein analysis techniques multimedia that is suitable for students' university cognitive development are considered to be developed in supporting biotechnology learning for pre-service biology teachers.</p><p class="Abstract"><strong>Abstrak:</strong><em> </em>Penelitian ini bertujuan untuk mengungkapkan persepsi dan kebutuhan calon guru biologi terhadap pembelajaran bioteknologi dan kebutuhan mereka akan media pembelajaran khususnya pada topik teknik dasar biologi molekuler.

Instrumen pengumpulan data terdiri dari kuesioner survei kesulitan topik bioteknologi dan kuesioner kebutuhan yang dirasakan (<em>felt needs</em>). Data tanggapan angket yang dianalisis menggunakan statistik deskriptif menunjukkan bahwa tingkat kesulitan aktivitas laboratorium teknik dasar biologi molekuler dianggap dalam kategori sedang. Rata-rata semua siswa melakukan teknik analisis DNA, dan hanya 55% dari seluruh siswa yang melakukan teknik analisis protein. Secara keseluruhan, siswa memiliki perasaan, pemahaman, dan kepercayaan diri pada tingkat sedang, sementara mereka merasa memiliki bantuan belajar yang sangat baik. Meski begitu, mahasiswa merasa membutuhkan sumber belajar berupa multimedia berbasis penelitian untuk mendukung pembelajaran pada topik praktikum teknik analisis biologi molekuler khususnya teknik analisis protein. Multimedia teknik analisis protein berbasis penelitian yang sesuai untuk perkembangan kognitif mahasiswa dinilai dapat dikembangkan dalam mendukung pembelajaran bioteknologi bagi calon guru biologi.</p></td></tr></tbody></table></div>

“…There have been numerous studies indicating the close interactions between the level of conceptual understanding and cognitive structures (Nakibog ˘lu, 2008). Although there is a considerable number of studies that investigated students' cognitive structures concerning different subjects including biology (Sikumbang et al, 2019), mathematics (Yang et al, 2018), and physics (de Jong and Ferguson-Hessler, 1986), the studies on how general chemistry concepts, particularly acid-base chemistry terms, are linked to each other and how they form students' cognitive structures are still limited.…”

This study aims to determine the cognitive structures of students at different educational levels (8th grade and 12th grade) related to acid–base chemistry. The research was designed as a case study and structured in two stages. The first stage analyzed concepts related to acid–base chemistry and their direction and strength in students’ knowledge structures. The second stage determined the descriptive and structural features of students’ knowledge structures related to acid–base chemistry in a more holistic approach. The study was carried out with a total of 160 students, 80 grade 8th and 80 12th grade students. A word association test (WAT) and the free writing technique (FWT) were used together. In the WAT, ten different frequency ranges were determined forming cognitive structure maps of the students. With high-frequency values on the map, it was found that the number of stimulus and response words decreased but the strength of associations increased. In frequency ranges where the frequency values of associations were low, it was found that the number of stimulus and response words increased and the cognitive structure organization was at the most advanced level compared to other frequency ranges, but the strength of associations was weak. In general, it was observed that there were no bidirectional and cross-associations between the concepts in the cognitive structures of the students about chemistry and that there was a static structure that included one-way associations only. Additionally, the concepts in the cognitive structures of students related to acid–base chemistry were analyzed in terms of their structural characteristics. It was found that, in the cognitive structures of the students there were no associations between many concepts that should be related to each other.
