PQcalc, an Online Calculator for Science Learners
Theis, Karsten
Journal of Chemical Education, v92 n11 p1953-1955 Nov 2015
PQcalc is an online calculator designed to support students in college-level science classes. Unlike a pocket calculator, PQcalc allows students to set up problems within the calculator just as one would on paper. This includes using proper units and naming quantities strategically in a way that helps finding the solution. Results of calculations come with units of measurement and are given with a reasonable number of significant figures. The features of PQcalc were chosen to allow learners to spend more time on scientific reasoning while figuring out and communicating well-annotated, structured, and mathematically correct solutions to quantitative problems.
