Teaching College Chemistry In The Time Of Covid-19 Pandemic: A Personal Account Of Teaching In The Old Normal Vs. The New Normal, Armando M. Guidote Jr

Chemistry Faculty Publications

The SARS CoV-2 (Severe Acute Respiratory Syndrome CoronaVirus 2), cause of COVID-19 (CoronaVirus Disease 2019) has afflicted close to 10 million people all over the world resulting to almost half a million deaths. This disease is severely contagious and necessitates social or physical distancing between persons. As such, traditional face-to-face learning is not advised and teachers need to shift to online teaching. There are challenges to online teaching and learning for students, teachers, and the higher education institute, e.g. hardware, bandwidth, and software issues. These will be difficult but these can be overcome eventually. This work is a personal account …

Assessment Instrument For Practicum Skills In Trimyristin Separation For Undergraduate Students, Naseer Ahmed, Senam Senam, Antuni Wiyarsi

Jurnal Inovasi Pendidikan IPA

Assessment of practicum plays an essential role in gaining knowledge and skill. Because practical work is an essential component of science courses, there were need to develop new instruments to examine practicum skill. To gain the purpose, Research and Development method used, Borg and Gall's model was adopted in this research. Observation sheets were used to obtain data. The qualitative data analysis technique was used to make coding. The data were described using descriptive statistics. It was used to determine the ability of students to practice in general, purposive sampling technique used for data collection. Products of practical's skills assessment …

Organic Chemistry Ii Lab Manual, Caitlyn Bailey

Senior Honors Theses

This project aims to supply a full lab manual and grading key for Organic Chemistry II, a class often taken by sophomores in Liberty University’s science degree programs. Properly applied laboratory experiments create a beneficial learning environment for science students by using hands-on procedures to transform intangible lecture concepts into concrete demonstrations. Lab work also fosters the development of problem-solving and critical-thinking skills that students need in research and the workplace. Thus, having a comprehensive lab manual is critical to students’ success and understanding in this upper-level class. This project adds to the experiments of Organic Chemistry II lab through …

Use Of Pope Engagement Index To Measure Cognitive Load Of Physical Modeling Activities In Organic Chemistry, Jenifer Calvert

Master of Science in Chemical Sciences Theses

Understanding how students learn and process information is critical to developing physical modeling activities that facilitate student learning by decreasing cognitive load in the working memory. Optimizing cognitive load during physical modeling activities in organic chemistry is the key to effective and efficient learning. Using EEG (electroencephalogram) and eye tracking technologies, researchers measured and recorded the cognitive processing of participants while they completed a chiral physical modeling activity. Analysis of the data using the Engagement Index developed by Pope et al provided information necessary to develop curriculum that does not undermine student learning due to excessive cognitive load.

Hitting Pause On Organic Chemistry, Jenny B. Vu

Interdisciplinary STEM Teaching & Learning Conference (2012-2019)

Written procedures for performing organic chemistry experiments are replaced by visual demonstrations that allow students to watch these videos at home and/ or in the laboratory. These previously recorded demonstrations allow students to watch, pause, and rewind the video to better understand laboratory techniques.
