EXPlainistry: Creating Documentation, Explanations, and Animated Visualizations of Chemistry Experiments Supported by Information and Communication Technology To Help School Students Understand Molecular-Level Interactions

Abstract

Given that students are constantly communicating and documenting special experiences in their social and private lives with digital devices, we suggest that this behavior could be used to record and deepen learning experiences -such as visualizing reactions at the molecular level -in a chemistry class. An example would be the creation of stop-motion videos to aid the visualization process for the documentation of experiments. This approach makes use of well-established techniques for documentation and visualization (e.g. static models or pictures) and combines them with dynamic approaches (e.g. animations) in order to enhance explanations of chemical experiments. Here, we describe how we use this approach to augment the novel teaching method, EXPlainistry (experiments explained in chemistry) with 5 th to 12 th graders, and consider how it helps students use ICT

Digitalisierung ‐‐ Perspektiven für den Chemieunterricht

“…Die ersten drei Funktionen -Experimentalwerkzeuge, Lernwerkzeuge und Lernbegleiter -haben das Lernen mit digitalen Medien im Fokus. 3) In der vierten Kategorie, Lerngegenstände, geht es um das Lernen über digitale Medien. 4) Experimentalwerkzeuge Als Experimentalwerkzeuge bereichern digitale Medien das Experimentieren, verändern es oder definieren es neu.…”

“…10) Sie können in die Rolle der Produzenten schlüpfen und selbst Videos aufnehmen, sodass sie durch Erklären lernen und gleichzeitig den Experimentierprozess dokumentieren. 3) Schüler können mit digitalen Medien gemeinsam gleichzeitig oder versetzt an einem Unterrichtsgegenstand arbeiten. 11) High-End-Anwendungen wie Augmented-Reality können individualisierte Hilfestellungen bieten, 12) mit ihnen lassen sich Chemielabore erkunden 13) oder Prozesse auf der Teilchenebene visualisieren.…”

Next generation of chemistry and biochemistry conference posters: Animation, augmented reality, visitor statistics, and visitors' attention

“…12 Previously, well-established techniques for documentation and visualization (e.g., static models or pictures) and their combination with dynamic approaches (e.g., animations) have been introduced in order to enhance explanations of chemical experiments. 13 On the other hand, smartphones have made a remarkable evolution in chemistry instruction, search for educational materials or even as a tool in the chemistry laboratories. 9,10 These interesting applications of smartphone are due to its portability and ability to install various software.…”

Using Video Documentation in Out-Of-School Lab Days as an ICT Learning and Diagnostic Tool

“…Students' diversity should be highly considered -comparable to common lessons -in order to induce learning processes successfully. The use of varied ICT tools and forms of experimentation is one possibility to offset students' diversity and, subsequently, to enrich their learning [5,6,7,8].…”

“…In addition, ICT tools as alternative forms of documenting experiments (e.g. videos, or podcasts) provide both, great potential for differentiation for heterogeneous learning groups and a diagnostic tool for teachers [8,9,10].…”
