Chapter 1: The Impact of COVID-19 on Science Education
In 2020, the COVID-19 pandemic swept across the globe, prompting lockdown measures aimed at curbing the virus's spread. This situation significantly disrupted education, influencing not only the learning experiences of students but also the well-being of educators. The repercussions extended beyond the classroom, potentially impacting economies and social inequalities on both local and global scales. However, this crisis also encouraged educators to adopt innovative technologies and rethink curriculum delivery.
In this discussion, I highlight a particularly positive outcome from the pandemic, focusing on high school and university chemistry and biology instructors who, despite lacking access to traditional laboratories, continued to offer practical science education to their students through home-based activities. These educators devised creative experiments and instrumentation that students could construct and utilize at home. Activities ranged from monitoring household chemical reactions using DIY devices to augmented reality applications that simulated molecular models and lab protocols on personal devices.
Section 1.1: DIY Science Experiments at Home
Low-cost laboratory tools, often crafted with minimal expertise and a bit of creativity, have been around for years but gained momentum recently due to advancements like 3D printing, improved information sharing, and initiatives promoting affordable educational resources. Organizations such as TReND in Africa have played a vital role in this movement.
Among the numerous DIY instruments developed within this geek culture, examples include open-source designs for spectrometers that can detect UV, visible, and infrared light, as well as DIY centrifuges, low-pressure pumps, pipettes, microscopes, and molecular biology kits. While some of these instruments require familiarity with electronics and optics, others can be assembled from common materials and 3D-printed parts.
Smartphones, with their array of sensors, have emerged as key tools for DIY science. Many free apps allow users to monitor and log various signals in real time, facilitating experiments without the need for complicated setups. For instance, educators have utilized webcam-based spectrophotometers to collect spectra from inexpensive DIY kits, enabling students to conduct a variety of analyses, such as observing color changes in chemical reactions.
Section 1.2: Augmented Reality in Education
The last decade has seen an explosion in the use of augmented reality (AR) across smartphones, tablets, and laptops, eliminating the need for specialized hardware. Even before the pandemic, many educators harnessed this technology to create engaging AR experiences for students. With widespread access to smartphones, these educational AR activities reached a vast audience, particularly those that are web-based and do not require software installation.
For instance, my colleagues and I developed a website called moleculARweb, which hosts several AR-based educational activities designed to help students visualize complex concepts in chemistry and structural biology. These interactive 3D models not only enhance understanding but also demonstrate how atoms form molecules, showcasing the dynamic nature of scientific interactions.
Chapter 2: The Role of Online Educational Content
The abundance of online educational resources has made complex subjects, even advanced topics like quantum physics, more accessible than ever. Numerous YouTube channels dedicated to science education have emerged, enhancing engagement through dynamic video content. Some of my preferred channels include Veritasium and PBS Space Time in English, along with Quantum Fracture and Date un Vlog in Spanish.
Video content is particularly effective in conveying information, often providing clearer explanations than static images or verbal descriptions alone. Many educators have transitioned to sharing their lessons online during the pandemic, offering free access to a wealth of practical experiments and tutorials, often delivered by experts in their respective fields.
Section 2.1: Developing Computer Skills Through Online Learning
The pandemic also presented an opportunity for students to enhance their computer skills. As time spent on computers increased, many educators introduced programming concepts and even bioinformatics to their students. Proficiency in programming languages like Python, along with HTML and JavaScript, has become invaluable for aspiring scientists, regardless of their primary focus. Platforms like Jupyter Notebooks and Google Colab have made learning programming enjoyable and productive.
Some Final Thoughts
The pandemic has left a legacy of innovative educational tools that may continue to shape our approach to learning. For instance, many university professors recorded lectures that are now freely accessible online, allowing them to enhance their teaching practices. In future classes, instructors could direct students to these resources, reserving in-person meetings for discussions and practical activities.
Moreover, the potential for hybrid learning environments, flexible assignment deadlines, and an emphasis on DIY experimentation at home alongside traditional lab work may redefine science education moving forward. Once again, it is the rich geek culture that has provided the means for this evolution.
