Development and Production of Interactive Videos for Teaching Chemical Techniques during Laboratory Sessions

Abstract

Success in undergraduate chemical experiments requires students to develop knowledge and skills of instrumentation, equipment and chemical techniques. In this technology report, we propose an adaptable and user focused strategy to improve students' foundational skill and proficiency with chemical laboratory techniques and instrumentation. The strategy is composed of multi-perspective filming of experimental activities using mobile phones or professional level filming to create videos that can be freely viewed by students in-situ during laboratory classes on a mobile device (iPad). Details of mixed digital approaches for a variety of chemical experimental techniques (10 examples) are compared for professional level filming and mobile phone filming. Results showed that both the accuracy and precision of the developed videos are highly suitable for teaching purposes. Use of mobile phone cameras permitted chemical techniques to be filmed from multiple angles in constrained spaces, such as fume hoods. A major benefit to students was the utility of the videos on portable devices, as students were informed by the video whilst setting up or performing the task in hand during laboratory sessions.

Online in No Time: Design and Implementation of a Remote Learning First Quarter General Chemistry Laboratory and Second Quarter Organic Chemistry Laboratory

“…6 Manuals, technique videos, readings, and instructor videos were already embedded in the ELN, LabArchives, and/or the learning management system, Canvas. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] Prelaboratory work consisted of online homework and completion of select portions of the ELN. 10,13,23,24 During the laboratory session, students also utilized the ELN to enter procedures, observations, and data.…”

The Study of Affective Value in Educational Video Production Style Using Kansei Engineering Method

“…A nationwide survey was conducted in 2018 by Kaltura about the prospect of interactive video possibly will play an important role in the forthcoming education, with 97% of respondents" feedbacks reported agreed [9]. An experiment was conducted during the laboratory sessions where the students watch the video tutorial through iPads, the way they behaved shows that as if they were searching for the convenience and the availability of interactive feature in a video [10]. Thereof, an educational video for higher institutions needs to be engaging and attractive enough for learners to stay tuned and utilize the video as their alternative method to studies.…”

Analysis of Effectiveness and Performance Prediction of Sports Flipped Classroom Teaching Based on Neural Networks

“…Flipped classroom [1][2][3] is a product of modern development, and internet technology is an important support for its implementation: teachers send teaching videos [4][5][6] made by themselves or by other teachers on the internet to students via the learning platform [7] so that students can complete preclass learning tasks under the guidance of teachers in the classroom. e flipped classroom is popular in theoretical subjects but is rarely used in physical education [8], which is a practical course.…”
