The aim of this research was to develop a STEAM-based program for teaching middle school students the concept of time to enhance their computational thinking skills. The proposed Time Teaching Program (TTP) consists of modules and activities on the definition of time, historical development of time measurement tools, universal time measurement…

Mode estimation, the visual determination of the proportions of the components of a rock, is a valuable tool in geology, providing one of the most efficient means of describing rock mineralogy and chemistry. However, current methods of teaching mode estimation suffer from the often-mediocre mode-estimation skills of the instructors. Fifty-nine…

Students need to achieve automaticity in learning mathematics without sacrificing conceptual understanding of the algorithms that are essential in being successful in algebra and problem solving, as well as in science. This research investigated the relationship between science-contextualized problems and computational fluency by testing an…

Enzyme kinetics is a difficult subject for students to learn and for tutors to teach. During the practicals included in the biochemical courses at the Faculty of Chemistry of Universidad Nacional Autonoma de Mexico, we found that the students acquire good training in the calculations to obtain kinetic parameters such as K[subscript m], V[subscript…
