Margaret K. Meadows – Journal of Chemical Education, 2024
This paper describes the design, implementation, and evaluation of an inquiry-based laboratory for sophomore-level organic chemistry into a mostly cookbook, existing laboratory curriculum. For the laboratory, students were required to generate their own procedures and use their own recorded data from prior laboratory assignments to identify an…

Kovacevic, Tanja; Skinner, Austin; Fisk, John D.; Fishback, Vanessa; Reed, Scott M. – Journal of Chemical Education, 2020
The complete structural analysis and resynthesis of an unknown compound, selected from a library of dipeptides, provided a framework for a course that built from expository experiments toward a guided-inquiry approach. We used this semester-long lab as a replacement for conventional second semester organic chemistry laboratory and successfully…

Muhammad Saefi; Widi Cahya Adi; Amining Rahmasiwi; Hidayati Maghfiroh; M. Eval Setiawan; Miza Nina Adlini; Syarif Rizalia – Journal of Biological Education Indonesia (Jurnal Pendidikan Biologi Indonesia), 2023
Laboratory course activities often focus on "cookbook style," so their activities have not yet integrated with scientific thinking as an essential aspect. In this research, the laboratory experience of microbial analysis techniques was redesigned using alternative inquiry to involve students in isolating and characterising yeast to make…

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…

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…

Nagma Zerin – Chemical Engineering Education, 2024
Project-Enhanced learning is an excellent way to facilitate student-centered learning along with traditional lecture-based learning. In this Class and Home problem, an example of Project-Enhanced learning is provided that can be used in the Mass and Energy Balances (MEB) course. The students solve this problem as part of a group while receiving…

Rattanakit, Parawee – Journal of Chemical Education, 2021
This paper describes an inquiry-based integrated laboratory project for green synthesis, characterization, and applications of silver and gold nanoparticles. In this project, students were able to choose their choice of plant extract as reducing and stabilizing agents, and the students also designed their own experiments. This course gave the…

DeFrancesco, Heather; Dudley, Joshua; Coca, Adiel – Journal of Chemical Education, 2018
An undergraduate experiment for the organic laboratory is described that utilizes microwave heating to prepare 5- substituted 1H-tetrazole derivatives through a (3 + 2) cycloaddition between aryl nitriles and sodium azide. The reaction mixture is analyzed by thin layer chromatography. The products are purified through an acid-base extraction and…

Hamideh Talafian; Morten Lundsgaard; Maggie S. Mahmood; Eric Kuo; Timothy J. Stelzer – Physical Review Physics Education Research, 2025
Although most teachers recognize the importance of taking investigative, open-ended approaches to students' learning experiences, implementing them in high school classes can be challenging for teachers. In this work, we analyzed data from multiple sources from a teaching Community of Practice (CoP) to investigate (a) barriers to taking an…

Michelle L. Kovarik; Betty Cristina Galarreta; Peter J. Mahon; Daniel A. McCurry; Aren E. Gerdon; Steven M. Collier; Marjorie E. Squires – Journal of Chemical Education, 2022
This article reports the results of a curriculum survey of 322 analytical chemistry instructors (92% U.S.-based) conducted during Spring 2021. This snapshot of current course formats, topics, and pedagogical methods will be useful to both seasoned and novice teachers of analytical chemistry. The majority of respondents reported that their major…

Natalie O'Neill – Irish Educational Studies, 2023
Internationally, second level curriculum policy for STEM education is concentrating its efforts on promoting curriculum-making pedagogies, with enquiry-based teaching and learning at the forefront of this change. Policy aspirations have not translated well into practice, evidenced by science practical lessons consistently being delivered as…

Tomas Shivolo; Hamza Omari Mokiwa – Journal of Education in Science, Environment and Health, 2024
Contemporary science teaching pedagogy in Namibia places a strong emphasis on fostering inquiry-based instruction and practical work in secondary school science education. In recent years, there has been a growing recognition of the need to move beyond traditional, rote-based methods towards more learner-centred approaches that encourage active…

Gloy, Kilian; Weyhe, Paul; Nerenz, Eric; Kaluschke, Maximilian; Uslar, Verena; Zachmann, Gabriel; Weyhe, Dirk – Anatomical Sciences Education, 2022
In order to improve learning efficiency and memory retention in medical teaching, furthering active learning seems to be an effective alternative to classical teaching. One option to make active exploration of the subject matter possible is the use of virtual reality (VR) technology. The authors developed an immersive anatomy atlas which allows…

Scientific competencies, as defined in the German competency framework, describe the ability to think independently and act scientifically which is a central component of medical education. This report describes integration of scientific competencies into anatomical teaching. Based on findings seen in two consecutive years of dissection courses,…

Newman, Karla – Journal of Chemical Education, 2018
Almost all commercial quadrupole ICP-MS instruments use collision/reaction cells to either attenuate spectral interferences or shift the analyte of interest to an interference-free "m/z" (e.g., by O addition). A laboratory practical was developed to introduce the students to the basic operating principles of ICP-MS using a hands-on…
