During the SARS-2-COVID pandemic our institution sought to continue the teaching and learning of experimental laboratories by designing, assembling, and delivering a microscale chemistry kit to the students' homes. Thanks to this approach students were able to perform [approximately]25 experiments during each one of the Fall 2020 and Spring 2021…

High-impact experiences, such as service-learning opportunities or hands-on laboratories, have been shown to enhance student learning, course satisfaction, and attitudes and behaviors. Thus, it is essential to incorporate these experiences into psychology curriculums when possible. However, it is also critical to analyze the impact of these…

A Computer-Aided Learning Package as Inquiry-Guided Learning (CALP/IGL) was implemented in a cooling tower experiment for 43 students enrolled in four sections of the Unit Operations Laboratory course in the chemical engineering program at Qatar University. The impact of this approach on the attainment of learning outcomes was evaluated. Results…

Video analysis is carried out for one-dimensional motion and collision experiments using Tracker. Physical variables, i.e. displacement, time, and velocity, can be deducted from the analysis and allows one to connect them to the equation of motion and energy conservation. Corresponding equations of motions are given without neglecting the effect…

This study has proposed a simple method to show the convective heat transfer. The object in this study is an air conditioner (AC) as a simple case of convection. In addition, AC is also easy to find in the class because most classrooms in Indonesia installed AC. Usually, a visualization needs special software (i.e. MatLab or others) and good…

This study aimed to develop alternative laboratory experiments (ALEs) in Chemistry 8 and evaluate the perceived improvement of the students' basic science process skills after utilizing the material. This employed a mixed method of research. Initially, a self-assessment survey questionnaire was used to determine the basic science process skills of…

Compared to aerobic catabolism, the theories and experiments of anaerobic catabolism are not covered in depth in biochemistry education curricula. Anaerobic digestion (AD) is a feasible method for converting common organic compounds to renewable energy-methane that has drawn a great deal of attention in practical applications. In this study, we…

A method to synthesize biaryls through the Suzuki-Miyaura cross-coupling reaction using a recyclable fluorous precatalyst is described. This laboratory experiment, which demonstrates the safety benefits of green chemistry, is integrated into an upper-division course. Besides simply using the catalyst for a reaction, students can reuse the catalyst…

How do different components of a learning environment contribute to learning in science? The study examines the contribution of laboratory experiments and computer model explorations to the learning of chemistry through a complex-systems approach. Specifically, junior high-school students' learning of chemistry via four different methods were…

[superscript 1]H NMR spectroscopy is a molecular characterization technique that is ubiquitously used in research and teaching laboratories alike. Strategic deuteration of molecules is a commonly employed technique in the deconvolution of [superscript 1]H NMR signals. Here this approach is applied in a second-year chemistry course in which…

Universities play an important role in society and in providing solutions for its problems. Environmental pollution is one of the most serious problems facing the world today. Thus, universities are increasingly including subjects related to the environment and its conservation both in their educational and research programmes. Generally,…

A fluorometer is a device that measures the spectroscopic properties of fluorescent materials, and fluorometry is used widely in chemistry research settings to characterize fluorescent samples. One of the obstacles faced by undergraduate programs looking to implement fluorometer-based experiments into their laboratory curriculum is the high cost…

Instructional physics labs offer students unique opportunities to develop an understanding of experimentation. By transforming labs to be more open ended and experimentation focused, instructors can better support student agency and choice. In this study, we examine students' overall sense of and perceptions about agency in two…

In this guided-inquiry lesson, students were tasked with determining the efficacy of an at-home drinking water filter at removing lead (Pb) from tap water using graphite furnace atomic absorption spectroscopy by determining the concentration of lead before and after filtration. The lesson was structured to allow students to choose and perform…

A newly developed laboratory learning program for high school chemistry courses is discussed, in which students discover the chemical mechanism governing exothermic phenomena during the reaction between a heating agent, namely, calcium oxide (CaO)--aluminum (Al) mixture, and water. Based on prior knowledge of simple heating agents such as CaO, the…
