![]() Students’ anonymous feedback responses were also evaluated. The use of these puzzles as a form of remote active learning was fortuitously evaluated immediately prior to and during the COVID-19 pandemic based on students’ online study behavior patterns, which captured some fascinating data on the frequency and timing of student online viewings. This work explores the performance of online postlecture chemistry crossword puzzles as revision aids for 132 first-year and 120 second-year undergraduate pharmacy students. The comparison demonstrated the new method to be more effective than the conventional method in facilitating the students in constructing knowledge through hands-on learning regarding the structure and characteristics of the periodic table, namely, the periodicity and the predictability of elemental properties. The scores of the tests conducted before and after the introduction to the periodic table to the treatment and control groups of the students, by the new and the conventional method, respectively, were analyzed. Students entered symbols of elements in the blank chart in a manner very similar to solving a crossword puzzle by making use of clues provided to them. In the new method, a blank chart of the modern periodic table was used as an educational aid. The study sample of about 100 students was identified on the basis of a test. ![]() This sample comprised over 200 school students learning introductory chemistry in India. A survey to test the effectiveness of this new method relative to the conventional method, involving use of a wall-mounted chart of the periodic table, was conducted on a convenience sample.

The Periodic Table Trivia: Crossword CluesĤ) 90 of the elements on the periodic table can be found in _.Ħ) The heaviest, naturally occurring element. That may be of interest to teachers as they plan to teach topics related to the periodic table. There is a Periodic Table Unit Plan available in the AACT library.An answer key document has been provided for teacher reference. ![]()
