Kari L. Lavalli; Maria E. Abate – Journal of College Science Teaching, 2024
Environmental science classes often ask students to examine changes in species or their environments to determine the human impact on a particular habitat or ecosystem. It is not always practical to take students out for a field study to do this kind of analysis; instead, the scientific method and diversity analyses can be utilized while students…

Bliese, Sarah L.; O'Donnell, Deanna; Weaver, Abigail A.; Lieberman, Marya – Journal of Chemical Education, 2020
A two to three period analytical chemistry experiment has been developed which allows second year students to explore chemical color tests used to detect adulterated pharmaceuticals. Students prepare several paper analytical devices (PADs) to generate positive and negative controls antibiotics, along with cutting agents such as starch and chalk.…

Bhukdee, Dhup; Limpanuparb, Taweetham – Journal of Chemical Education, 2020
An experiment to match five white solids with ascorbic acid, citric acid, potassium hydroxide, sodium chloride, and urea is reported here. This 4 h experiment is an integrated practice of two experimental techniques, calorimetry and titration. Students conduct an extensive literature search on the properties of the five compounds and plan the…

Ibiagbani M. Max-Harry; Grace P. Counts; Craig S. Nunemaker; Nicholas B. Whitticar – Journal of Chemical Education, 2023
Enzyme-linked immunosorbent assay (ELISA) is a valuable tool in various chemical and biological fields for investigating the presence and quantity of proteins of interest in given samples. The high importance of the assay makes it widely used in biological research and hence a crucial skill to master for up-and-coming scientists. A major…

Khan, Latifa B.; Tsai, Jia-Yun C. – Journal of Biological Education, 2020
Enzyme-Linked Immunosorbent Assay (ELISA) is a versatile and widely used technique to detect and quantify small molecules in various clinical and analytical applications. It is also an effective tool for demonstrating the specificity between antibody and antigen to students across diverse disciplines. However, undergraduate laboratories often face…

Çingil Baris, Çigdem – Biochemistry and Molecular Biology Education, 2022
Along with the COVID-19 pandemic, universities in Turkey as well as all over the world have started to carry out their education activities with the distance education method. In this case, many difficulties were encountered in the application of the Biology course, which is one of the applied courses carried out in the laboratory. Virtual…

Mosiagin, Ivan; Pallitsch, Katharina; Klose, Immo; Preinfalk, Alexander; Maulide, Nuno – Journal of Chemical Education, 2021
Most of the available information on studying under the challenging conditions brought about by the COVID-19 pandemic emphasizes a variety of aspects on how to digitalize the whole teaching process. Thus, several useful and potentially game-changing strategies have been reported recently. In contrast to the digitalization of teaching, in this…

Pergola, Michael; Britson, Carol; Schaefer, Audra – HAPS Educator, 2017
There is room for improvement in the amount of active learning that takes place during physiology laboratory exercises. This paper describes a protocol designed to examine the human dive response, with the goal of creating an integrative laboratory experienced focused around improving active learning. The objectives of this laboratory exercise…

Stewart, Lauren; Ross, Donna; Elliot, Kimberly – Science Teacher, 2019
This paper highlights learning supports associated with genetics lessons that were implemented in a urban high school biology classroom. The supports provided access to science content for ELLs [English language learners], students with IEPs [individualized education programs], and struggling readers during an introductory unit on genetics. Due to…

Barkley, Meg – Issues in Science and Technology Librarianship, 2018
Online tutorials are a way many librarians connect with students. The main benefit is the ability to reach more students than traditional face-to-face instruction sessions. In 2016, the Life & Health Sciences Librarian received instruction session requests for a freshman biology lab to teach students how to search for articles and use proper…

David C. Owens; Cindi Smith-Walters; Angela T. Barlow – International Journal of Designs for Learning, 2019
In this design case, we describe our work to develop a gameful learning design for use in an introductory, undergraduate biology laboratory course for science majors. Our design team included three university-based mathematics and science educators and a biologist responsible for the management of curriculum and instruction in the course under…

Nash, Troy R.; Yang, Suann; Inman, John C. – American Biology Teacher, 2015
We describe an alternative to the kinds of observation-based lab exercises that are often used to cover animal and plant evolution with respect to transitioning from aquatic to terrestrial habitats. We wrote this activity to address these objectives, but also to model the process of scientific inquiry and to require students to collect and analyze…

Silberman, Robert; And Others – Journal of Chemical Education, 1987
Discusses the need to develop laboratory practical examinations in chemistry which attempt to measure students higher order thinking skills and conceptual understanding rather than simply their laboratory skills. Examples of examination questions being used in general chemistry laboratory courses at the State University of New York at Cortland are…

Washington School District, Phoenix, AZ. – 1986
In an effort to improve the science education program in the Washington School District (Phoenix, Arizona) the school system focused its efforts in the 1983-84 school year on the development of an activity oriented laboratory science program for grades 4-6. This document describes the plan for implementing that program. The implementation…
