Carmen Velez; Kristie Cheng; Sabrina Woodward; Noor Nazeer; Gabriela Nicole Hislop Gomez; Cody O. Crosby – Journal of Chemical Education, 2024
Many undergraduate chemistry and biochemistry students pursue careers in healthcare. Biomaterials, designed to harmonize with the complexity of the human body, have become increasingly significant in medicine as implants, drug delivery vehicles and tissue scaffolds. We believe it is essential that undergraduates are exposed to biomaterial…

Gericke, Niklas; Högström, Per; Wallin, Johan – Studies in Science Education, 2023
We present an integrative mixed-methods systematic review of research on laboratory work in secondary-school science education from 1996 to 2019. The aim of the study is to identify important aspects of how to successfully make use of laboratory work as a science-teaching strategy in secondary schools. By engaging teachers, our study uses a…

The COVID-19 outbreak represented a remarkable challenge in universities and colleges since it forced the transition from a face-to-face model in classrooms and laboratories to a remote, online model using computers, tablets, and cell phones. In Mexico and other Latin American countries, the return to educational activities was a slow-paced…

Glenn Arthur Garcia; Sergio M. Abit Jr.; Jason Warren – NACTA Journal, 2024
Laboratory classes effectively enhance student understanding and appreciation of course concepts. With course delivery suddenly shifted into the online format due to the COVID-19 pandemic, four laboratory exercises in each of two introductory-level soil science courses were converted into virtual sessions delivered in the form of…

Juan M. Sanchez – Journal of Chemical Education, 2023
Descriptive statistics involves summarizing and organizing data so that they can be easily understood. Even though these are basic and simple concepts, many applied science students have misconceptions about their use in applied experiments in the laboratory. Students usually receive limited or no training in how to understand the meaning of the…

Chen, Yu; Lee, Jiwon; Moon, Su Jin; Jung, Pyung Kang; Cho, Youngsaeng; Kim, Jung Bog – Physics Education, 2021
This study is the result of a quantitative analysis of the previous paper reporting on four cases in which an LED is turned on by charge transfer occurring during the electrostatic induction process in a conductor connected to the LED. We were able to measure the charge transfer by using charge sensors and analyze experimental results by applying…

Qiu-ting Huang; Yi-dan Zuo; Zhu Zhu; Liu Yang; Zhong-qun Tian; Guo-kun Liu – Journal of Chemical Education, 2024
Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…

Adisu Daniel; Desta Gebeyhu; Shimeles Assefa; Tsedeke Abate – Cogent Education, 2023
Although laboratory work is considered a significant factor in helping students develop their science process skills and cultivate alternative knowledge construction, there are still gaps in the selection, integration, and implementation of the basic elements in physics laboratories. In this study, three modified guided discovery and conventional…

Krzysiak, Amanda; Doyle, Caroline; Huff, Mary O. – Biochemistry and Molecular Biology Education, 2022
Project-based (research-driven) laboratory courses stimulate student involvement, improve critical thinking and initiate cooperative learning. To this end, a 7-week laboratory project was designed for a sophomore cell biology course to reinforce the fundamental relationship between genotype and phenotype using yeast alcohol dehydrogenase I (ADH1).…

McKinney, Daniel – Science Teacher, 2020
Teaching the tools and concepts associated with modern physics can often be a daunting and difficult task for secondary science teachers. Classical physics is often perceived as intimidating and complex in its own right. Modern physics addressing quantum phenomena where Newtonian laws break down is even more abstract for learners. However,…

Cooper, A. C.; Southard, K. M.; Osness, J. B.; Bolger, M. S. – CBE - Life Sciences Education, 2022
Limited access to undergraduate research experiences for science, technology, engineering, and mathematics students has led to creation of classroom-based opportunities for students to participate in authentic science. Revising laboratory courses to engage students in the practices of science has been shown to have many benefits for students.…

Kylie L. Luska – Journal of Chemical Education, 2022
A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

Kapici, Hasan Ozgur; Akcay, Hakan; Cakir, Hakki – International Journal of Science Education, 2022
Inquiry-based learning can be an effective approach when students are provided with sufficient guidance. However, there is an ongoing debate among practitioners about the nature, type, and level of such guidance. This study investigated the effects on middle school students' (N = 116) conceptual knowledge and inquiry skills acquisition of…

The study aimed to identify the effect of the interactive drills using the dry laboratory on the acquisition of scientific concepts and laboratory skills in science among the ninth-grade female students in Palestine in light of their thinking styles. The study used quizzes of experimental method. The sample consisted of 68 female students…
