Patricia Prodan; Matteo Neffat; Renato Bonomi – Journal of Chemical Education, 2024
The activity proposed in this study aims to investigate the equilibrium between the liquid and vapor phases in a mixture of water and acetic acid, both of which are volatile substances. High school students can easily determine the composition of the liquid phase and its corresponding vapor phase at equilibrium using a simple and conceptually…

Dean J. Campbell; Thomas S. Kuntzleman; Kayla Lippincott; Abe Yassin; Khitab Dar; Q. Ott – Journal of Chemical Education, 2023
The relationship between surface area and dynamics of processes can be demonstrated by adding iron at room temperature to liquid nitrogen. The rate at which the liquid nitrogen boils to produce gas is related to the surface area of the iron. Adding iron in the form of consistent units that have measurable sizes can be readily connected to…

Antonio Va´zquez-Lo´pez; Joaqui´n Artigas-Arnaudas; Javier Bedmar – Journal of Chemical Education, 2024
Herein we propose the implementation of an "escape room" activity to reinforce chemistry-related concepts for students of the Bachelor of Arts and Fashion. In this work, a combined online and offline activity is developed, easily adaptable to different environments. The online activity consists of 5 blocks of multiple-quiz questions…

Baldwin, Nicole; Orgill, MaryKay – Chemistry Education Research and Practice, 2019
Practicing chemists use models, diagrams, symbols, and figures to represent phenomena which cannot be detected by the human senses. Although research suggests that these external representations (ERs) can also be used to address the challenges that students have in learning chemistry, it is not clear how instructors' use of ERs aligns with their…

Matheus Almeida Bauer Zytkuewisz; Denis Ricardo Martins de Godoi; Amadeu Moura Bego – Journal of Chemical Education, 2023
This study's general theme revolves around practical work in chemical education, and its scope is the employment of a novel inquiry strategy combined with a new openness level. We investigate how the controlled positive error, a new device for inquiry activities developed by us, affects undergraduate students' experience of an experiment and…

Monsurat M. Lawal; Tugba G. Kucukkal – Journal of Chemical Education, 2024
An undergraduate-level Computational Chemistry project was incorporated initially into a Physical Chemistry course and then into the laboratory curriculum in the subsequent application. Before the introduction of the project, the lectures covered quantum chemistry, spectroscopy, and kinetics while simultaneously including computational chemistry…

McPherson, Heather – Teaching Science, 2018
In this article, the author describes a chemistry gas experiment that she developed with the intent of integrating inquiry and Problem-Based Learning (PBL). The lab activity follows the principles of Ambitious Science Teaching (AST). Teachers (1) engage students with important science ideas, (2) elicit students' ideas while making visible what…

Dounas-Frazer, Dimitri R.; Ríos, Laura; Pollard, Benjamin; Stanley, Jacob T.; Lewandowski, H. J. – Physical Review Physics Education Research, 2018
The ability to develop, use, and refine models of experimental systems is a nationally recognized learning outcome for undergraduate physics lab courses. However, no assessments of students' model-based reasoning exist for upper-division labs. This study is the first step toward development of modeling assessments for optics and electronics labs.…

Introducing Pharmaceutics to Middle School Students Using with Hypothesis-Driven, At-Home Activities
Riya Singhal; Anju Gupta – Journal of Chemical Education, 2023
Since the COVID-19 pandemic, there has been an increase in healthcare and related science majors at the undergraduate level. This presents an opportunity to introduce health science training in middle school science classes to familiarize students to various healthcare-related fields. The pharmaceutical science-based hands-on activities for middle…

Basso, A.; Chiorri, C.; Bracco, F.; Carnasciali, M. M.; Alloisio, M.; Grotti, M. – Chemistry Education Research and Practice, 2018
Improving the interest of high-school students towards chemistry (and science in general) is one of the goals of the Italian Ministry of Education. To this aim, we designed a context-based activity that actively involved students in six different laboratory experiences interconnected by a case study of the murder of Miss Scarlet, from the famous…

Gorospe, Kelvin D.; Fox, Bradley K.; Haverkort-Yeh, Roxanne D.; Tamaru, Clyde S.; Rivera, Malia Ana J. – Journal of Geoscience Education, 2013
We present a hands-on, inquiry-based activity exploring how CO[subscript 2] input to seawater affects the skeletons of several species of reef-building corals and other marine organisms by testing for changes in pH and calcium ion concentrations. Originally developed to inspire and recruit high school students in the state of Hawai'i into the…

Monge, David – Journal of Chemical Education, 2015
An experiment carried out by advanced undergraduate students in a project-based laboratory course is described. Taking into account the positive effects of working in teams, which has been key for successful research in industry and academia, a cooperative learning experience in the laboratory was developed. Students working in teams of four…

Supasorn, Saksri – Chemistry Education Research and Practice, 2015
This study aimed to develop the small-scale experiments involving electrochemistry and the galvanic cell model kit featuring the sub-microscopic level. The small-scale experiments in conjunction with the model kit were implemented based on the 5E inquiry learning approach to enhance students' conceptual understanding of electrochemistry. The…

Bumbacher, Engin; Salehi, Shima; Wierzchula, Miriam; Blikstein, Paulo – International Educational Data Mining Society, 2015
Studies comparing virtual and physical manipulative environments (VME and PME) in inquiry-based science learning have mostly focused on students' learning outcomes but not on the actual processes they engage in during the learning activities. In this paper, we examined experimentation strategies in an inquiry activity and their relation to…

Lopez-Arias, T.; Calza, G.; Gratton, L. M.; Oss, S. – Physics Education, 2009
A simple experiment is presented to visualize inferior and superior mirages in the laboratory. A quantitative analysis is done using ray tracing with both photographic and computational techniques. The mirage's image, as seen by the eye or the camera lens, can be used to analyse the deflection and inversion of light rays. (Contains 6 footnotes, 1…
