Muhfahroyin Muhfahroyin; Susriyati Mahanal; Suratno Suratno; Agus Sujarwanta – American Biology Teacher, 2025
The mastery of the ability to identify and describe plant morphology is an essential aspect of studying biology. The skill of describing plants can be developed through diverse learning resources, including textbooks and contextual materials. Therefore, this study aims to determine students' ability to describe the morphology of plants using a…

Daisuke Kajiya – Journal of Chemical Education, 2023
The yellow-blue color pair has been used in creative artwork such as paintings and designs and in color engineering. Herein we present a method for using the yellow-blue combination in a chemistry lesson dealing with [pi]-conjugated molecules for first-year undergraduate students who are not science majors. The lesson begins with an introduction…

Bruna M. Damm; Izabela de F. Schaffel; Gabriel F. S. dos Santos; Lilia E. S. Azevedo; Rafael de Q. Ferreira; Paulo R. G. de Moura – Journal of Chemical Education, 2023
Antioxidants are molecules that act against free radicals, and this effect can bring many benefits to health and society. Antioxidants can be found in various matrices of nature, such as fruits and plants. Some studies have shown that "Rhizophora mangle," a typical mangrove plant, is rich in antioxidants. People report its use for…

Philip A. Kocheril; Makaela M. Jones; Jessica Z. Kubicek-Sutherland – Journal of Chemical Education, 2022
Raman scattering spectroscopies are important analytical tools in modern chemistry. Here, we describe the construction of the unamplified Raman scattering analysis (URSA) instrument: an inexpensive, open-table Raman spectrometer that uses a 532 nm diode-pumped laser as a light source. Upon application of this spectrometer to DNA extracted from…

Mayta, Martín L.; Dotto, Marcela; Orellano, Elena G.; Krapp, Adriana R. – Biochemistry and Molecular Biology Education, 2022
The CRISPR/Cas9 system is widely used for editing genes in various organisms and is a very useful tool due to its versatility, simplicity, and efficiency. To teach its principles to post-graduate students we designed a laboratory activity to obtain and analyze PDS3 mutants in "Arabidopsis thaliana" plants consisting of: 1) Design of…

Wawan Wahyudi Efendi; A. Atiqoh; Hari Karyono – Journal of Biological Education Indonesia (Jurnal Pendidikan Biologi Indonesia), 2023
Many ferns learning in higher education were organized conventionally and relied only on textbooks. Moreover, it is not in accordance with the characteristics or learning styles of Generation Z (Gen Z). This research aims to produce Pteridophyte Smart Cards (PSC) as a learning media by integrating cards containing real images of ferns with QR Code…

Zidny, Robby; Eilks, Ingo – Education Sciences, 2022
This study shows how students can learn about green and sustainable chemistry by using the knowledge perspective of a local indigenous culture as a starting point. This learning approach encourages students to learn chemistry by connecting culture with learning about green chemistry. The cultural context selects the use of a phytochemical agent…

Huan Tong; Renjie Cui; Be´atrice Lego; Kris S. Kim – Journal of Chemical Education, 2023
A community-engaged learning experiment was developed for an introductory analytical chemistry course at the University of Toronto Scarborough in collaboration with Campus Farm. The experiment introduced students to the application of analytical techniques to studying environmental samples. More specifically, students investigated the potential of…

Ciaccio, James A.; Hassan, Kareem – Journal of Chemical Education, 2020
Column chromatography of photosynthetic plant pigments is a common experiment in introductory laboratory courses for science majors and nonscience majors alike. We report a simple, rapid, reproducible, and small-scale solid--liquid extraction of photosynthetic pigments from inexpensive, store-bought dried herbs that affords a dark-green extract…

Zhang, Chang-Dong; Hu, Xin-Yuan; Wang, Huai-Song; Yan, Fang – Journal of Chemical Education, 2021
A comprehensive undergraduate experiment about extraction, separation, and identification of essential oils (EOs) from a natural plant is described. "Acori tatarinowii" Rhizoma (ATR) was used as the raw plant material. Two devices (Soxhlet and Clevenger) with different extraction principles were employed for EO extraction from ATR,…

Liu, Jinjie; Cook, Ron; Danhof, Linda; Lopatto, David; Stoltzfus, Jon R.; Benning, Christoph – Biochemistry and Molecular Biology Education, 2021
A complex research project was translated into a Course-based Undergraduate Research Experience (CURE), which was implemented in sections of an introductory Cell and Molecular Biology laboratory course. The research laboratory generated an engineered plant line producing a growth-inhibiting, lipid-derived plant hormone and mutagenized this line.…

Tise, Joseph C.; Sperling, Rayne A.; Dann, Michael S.; Young, Taylor M. – CBE - Life Sciences Education, 2023
Analogical reasoning is an important type of cognition often used by experts across domains. Little research, however, has investigated how generating analogies can support college students' self-regulated learning (SRL) of biology. This study therefore evaluated a contextualized cognitive learning strategy intervention designed to teach students…

Gould, Kevin S.; Gilbert, Amanda; Pike, Adrian J.; Menzies, Ignatius J. – Journal of Biological Education, 2019
Microscopy skills are critical for many aspects of biology, yet they are notoriously difficult to teach, especially to large classes. We trialled the use of widescreen monitors with touch-screen capability connected to compound microscopes in an introductory-level plant biology lab. Working in teams, students used the screens to interpret,…

Kuzmenko, Tatiana; Sharma, Ashwarya; Willette, Demian A. – American Biology Teacher, 2021
Hands-on, inquiry-based laboratory activities are excellent opportunities to introduce first-year undergraduate students to the lab environment and to catalyze new interest in topics they may not yet know or be as enthusiastic about studying. We describe a multisession introductory laboratory activity that couples the research areas of medicinal…
