Liying Zhu; Daner Sun; Ma Luo; Weidong Liu; Song Xue – Journal of Science Education and Technology, 2024
The laboratory plays a crucial role in science education. However, teacher education for pre-service teachers' design performance in the laboratory is still challenging. This study paved the way for redesigning traditional laboratory teaching into a student-centered approach: inquiry-based design thinking (IBDT). To investigate the impact of the…

Ronald L. Reyes; Kristina P. Isleta; Jennifer D. Regala; Daisy Mae R. Bialba – Journal of Computer Assisted Learning, 2024
Background: The adoption of virtual laboratories (VLs) has experienced a significant surge, catalysed by the global changes in the educational landscape, notably influenced by the COVID-19 pandemic. Originally supplementary to traditional in-person laboratory experiments, VLs swiftly transitioned into a primary source of hands-on laboratory…

George Lisensky – Journal of Chemical Education, 2022
Starting with a double replacement reaction in alcohol between Ni(H[subscript 2]O)[subscript 6](NO[subscript 3])[subscript 2] and NaX, students exploit solubility differences to produce a solution of NiX[subscript 2] and a NaNO[subscript 3] precipitate. They then synthesize a bis(N,N-diethylethylenediamine) Ni(II) complex with chloride, bromide,…

The Making Introductory Courses Real while Online (MICRO) laboratory project was developed to meet the need for hands-on experiments, focused on topics in analytical chemistry, to be delivered safely remotely or in a socially distanced in-person lab. Unlike more traditional lab experiments, MICRO laboratories use only microgram or nanogram amounts…

Mason, Kevin; Schieffer, Steve; Rose, Tara; Matthias, Greg – Science Teacher, 2022
A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

Thacker, Beth – Physical Review Physics Education Research, 2023
[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] This paper presents a historical analysis of the development, implementation, research, and assessment of an evidence-based introductory algebra-based physics course. The course is laboratory based and taught with an inquiry-based…

Sarah Ritter; Liza Abraham – Journal of Chemical Education, 2022
This project introduces green chemistry to the undergraduate laboratory through two pedagogical techniques: undergraduate research and guided-inquiry. Through these two learning activities, an efficient synthetic procedure for the PRINS cyclization of citronellal into isopulegol, focused on minimizing negative environmental impact, was developed.…

Christianson, Anna M.; Waters, Carolyn A. – Journal of Chemical Education, 2022
We describe a guided-inquiry laboratory experiment for instrumental analysis in which our students test an improved protocol for the recycling of silver chloride to produce nontoxic waste. Students are provided with samples of silver chloride that they created as waste products in a previous lab experiment and tasked with performing a stepwise…

Ani Nvehr Davis; Stephan Georgiev Michaelov; Clayton Joshua Rogers; Leighann Rose Weber; Brycelyn Marie Boardman; Gretchen Marie Peters – Journal of Chemical Education, 2022
Polymer chemistry is an important subject in the undergraduate chemistry curriculum. It is required for ACS-certified degrees and significantly connects to real world issues like the plastic waste crisis. While some concepts of polymer chemistry can be incorporated into lecture courses, students' understanding of material properties and…

Wathen, Bailee; Lanehart, Emily; Woodis, Lena A.; Rojas, Anthony J. – Journal of Chemical Education, 2021
This three-part laboratory experiment investigates key aspects of the Buchwald-Hartwig amination cross-coupling reaction through guided-inquiry learning strategies. The first part of this experiment utilizes high-throughput experimentation techniques to reinforce, explore, and extend fundamental concepts that are represented in the classroom,…

Cai, Bei; Mainhood, Lindsay A.; Groome, Ryan; Laverty, Corinne; McLean, Alastair – Physical Review Physics Education Research, 2021
We investigated physics students' behavior in a second-year laboratory by analyzing transcribed audio recordings of laboratory sessions. One student group was given both a problem and procedure and asked to analyze and explain their results. Another was provided with only the problem and asked to design and execute the experiment, interpret the…

Alexander Grushow – Journal of Chemical Education, 2022
A revised version of a traditional physical chemistry laboratory experiment has been developed to enhance student discussion in the laboratory and to improve students' connections between physical chemistry concepts and real molecular systems. In this experiment, students explore the keto-enol tautomerization of 2,4-pentanedione. However, unlike…

Sun, Maolin; Liang, Chaoming; Shen, Xinyuan; Li, Jianchang; Cheng, Ruihua; Ye, Jinxing – Journal of Chemical Education, 2021
The laboratory experiment regarding esterification of ethylene glycol with acetic acid to ethylene glycol diacetate using resin catalysts in a continuous flow was designed to carry out the reaction in a flow through an inquiry-guided approach. Incorporating the burgeoning field of continuous flow chemistry into the educational infrastructure, the…

George-Williams, Stephen R.; Ziebell, Angela L.; Thompson, Christopher D.; Overton, Tina L. – International Journal of Science Education, 2020
Previous work at Monash University has shown that students recognise that inquiry-, problem-, context- and industry-based experiments were better contextualised, more open to decision making and aided in the development of scientific and transferable skills. This study investigated whether these gains persisted over a longer time scale, rather…

Borrull, Anna; Valls, Cristina – Journal of Turkish Science Education, 2021
Practical work as observation and experimentation are vital parts of science education. One way to accomplish this is by applying inquiry-based learning in laboratory activities. Inquiry enhances the development of scientific skills as well as the learning of the scientific concepts. In the present article, a laboratory activity was developed to…
