Athavan Alias Anand Selvam; Subhadip Senapati – Journal of Chemical Education, 2023
Research-based pedagogy was implemented to enhance high school students' learning outcomes in basic organic chemistry. Flipped learning and structured peer work have been offered to grade 10 students(N = 12) during the course with appropriate classroom facilities, supervised by two facilitators. The preclass and in-class activities were designed…

Ha, Sangwoo; Kim, Minchul – Science & Education, 2020
Experiment is understood as a core activity in science education as well as science in general. Despite many efforts to improve science education in the laboratory, a cookbook style of verification experiments often dominate school science. In this study, we conducted an open laboratory activity that provided students with an opportunity to think…

Varela, Carla L.; Cabral, Ana M. T. D. P. V.; Barbosa, Isabel R.; Costa, Saul C.; Silva, Elisiário J. T.; Roleira, Fernanda M. F. – Journal of Chemical Education, 2020
Amides are usually prepared using amines and acyl halides, which often implies a two-step procedure. Alternatively, coupling reagents can be used in a single-step reaction with good yields, which seems to be suitable for organic chemistry laboratory classes. This work was designed to synthesize "N"-hexylcinnamamide through a one-step…

Pathak, Praveen; Patel, Yogita – Physics Education, 2020
A phone emitting sound of a fixed frequency is sliding on an inclined plane and approaching a second phone kept at the bottom of the plane. The detected frequency versus time data by the second phone are used to calculate the acceleration of the sliding phone. The primary objective of this paper is to calculate the sliding friction between the…

Risk Mora, David Yamil; Durango Idarraga, Sebastian; Cardenas Montoya, Paulo Cesar – Physics Education, 2020
Collisions are a key topic in physics and engineering education. An experiment with multiple body one-dimensional collisions is presented, aiming to measure relevant physical quantities by tracking the motion of the system of particles during the collision. Relations between different physical quantities can be explored in the experiment, such as…

Martínez, Violeta A.; Ibanez, Jorge G. – Journal of Chemical Education, 2020
This activity allows students to visualize how to obtain different stoichiometries with various techniques in a single experiment. The involvement of three phases adds to the student's interest. Instructional materials are provided to facilitate the experimental procedures, interpretation of results, and error analysis. The reaction of Li from a…

Lima, E. A.; Dutra, R. S.; Souza, P. V. S. – Physics Education, 2020
We propose a semiquantitative experiment that associates video-analysis and ordinary procedures of experimental physics whose objective is to investigate the dual character of Oobleck, a mixture of cornstarch in water, which appears thicker or thinner depending on how it is physically manipulated. The results are presented and interpreted taking…

Emden, Markus; Gerwig, Mario – Science & Education, 2020
Michael Faraday is considered one of the greatest science lecturers in history. He popularized the Christmas Lectures as a format of science communication that has survived until today in the Royal Institution of Great Britain. Especially, his "Chemical History of a Candle" has become a classic of science communication that has inspired…

D'Angelo, John G. – Journal of Chemical Education, 2020
The suspension of in-person classes brought about by the COVID-19 pandemic necessitated adjustments to all manner of instruction. Laboratory instruction was particularly challenged since the primary response was to deliver content remotely, i.e., online. In an effort to reinforce laboratory topics and engage students, five click-through organic…

In light of the COVID-19 pandemic situation, the separation of the primary colors of ink markers and food coloring was performed using a simplified column chromatography setup at home to accomplish the educational outcome of the course. The virtual class instruction, for the students enrolled in the "Organic Techniques Laboratory"…

Rinaldi, R. Gustav; Fauzi, Ahmad – Physics Education, 2020
The recent works of oscillators are mainly focused on underdamped oscillation. Therefore, the writer proposes an experimental apparatus to demonstrate all types of damped harmonic oscillation. The apparatus utilizes an Arduino for data acquisition and an Excel spreadsheet for data analysis. By using this apparatus, the type of damped harmonic…

Zollman, Dean; Bearden, Ian – Physics Education, 2020
Light emitting diodes have been used to determine Planck's constant in introductory physics laboratories. One common method relies on the energy of the light emitted by the LED and its relation to the energy gap in the solid of which the diode is composed. However, there could be a problem with the data that are collected for this experiment. For…

Lam, Chun Ho; Jackson, James E. – Journal of Chemical Education, 2020
Electrocatalytic hydrogenation of acetol (IUPAC: 1-hydroxy-2-propanone), a species formed upon thermal liquefaction of biomass, can be achieved using inexpensive objects: filter paper, coins, batteries, salts, and water. This simple example demonstrates that "green" chemical transformations can be achieved with familiar items and helps…

Sakon, Takuo; Inoguchi, Kaname – Physics Education, 2020
In this article, we examine the rotation angle dependence of a hand-made fan-type variable capacitor for use in physics experiments in university classes. We made two circular bakelite plates, and the two terminal plates of the capacitor were 90° fan-type copper disks. The capacitance varied linearly with the rotation angle. The standard deviation…

Walden, Sarah L.; Frisch, Hendrik; Unterreiner, Barbara V.; Unterreiner, Andreas-Neil; Barner-Kowollik, Christopher – Journal of Chemical Education, 2020
The prompt transfer of cutting-edge science into students' curricula is a challenging task. Often research experiments are too complex or expensive to be translated into a secondary or tertiary education setting. Herein, we introduce a laboratory experiment that translates the recently developed research technique of a wavelength dependent,…
