Many students, especially non-science majors, hazardous chemistry. The first lesson in an introductory chemistry course is generally concerned with how to interpret the periodic table of elements, but its complexity can be overwhelming to students with little or no previous exposure. Now, researchers reporting to ACS Journal of Chemical Education Introduce an innovative way to make learning about elements more acceptable by using “pseudo” periodic tables filled with superheroes, foods, and apps.
One of the fundamental subjects taught in first-year undergraduate chemistry courses is organization and layout. periodic table of elements. However many University students This is a difficult and difficult subject to master, inspire professors to seek new ways to engage their students and make its concepts more accessible. Previous academic studies presented tables in a variety of forms, such as crossword puzzles and cartograms, to address a variety of learning styles. Gregory Watson and colleagues argued that starting the periodic table with familiar objects may also help. And instead of immediately teaching full details, researchers wanted to focus on some of its key features first, using contemporary, engaging, and multi-tiered tactics.
The team presented first-year chemistry students with items manufactured or pseudo-periodic tables with items they had previously been prospecting, including fruits and nuts, superheroes, iPad apps, and meats. Pseudo-periodic versions replaced single-item elements to demonstrate one or more concepts needed to understand the trends and layout of the actual chemical one. For example, Superman’s table features characters such as Superman, Wonder Woman, and Green Lantern, with icons inspired to discuss the group by ability, power, gender, and other qualities – such as elements. Is organized in real form. periodic table Based on their similarity. More than 75% of the students taught with this strategy have considered it, to some extent, very useful. Increase right answer Related to the topic on the midterm exam suggested that these periodic tables improved students’ understanding. Researchers say familiar things reduce stress and help students successfully build their base chemistry Knowledge.
