During the pandemic and lockdown situations of the last few years, we transitioned to online, physical, and hybrid education approaches at various times. We had difficulty teaching multiple calculus and analytical geometry units online. In light of the current situation, a graphical user interface (GUI) teaching tool has been developed to teach…

Biological systems exhibit strong dynamic variations; for example, a system may have a tendency towards either a steady state, periodic behaviour or chaotic oscillations. These findings, explained by dynamic systems theory, have allowed researchers to formally relate a wide variety of systems, such as the theory of rumour propagation, glucose…

Tootsie Pops, manufactured by Tootsie Roll Industries of Chicago, Illinois, are spherical hard-candy lollipops with a chocolate-flavoured, chewy center. While Tootsie Pops have been around since 1931, it was a television commercial made in 1969 that captured the attention of many. The commercial, an amusing animated cartoon, posed the following…

Inservice teachers need ways to gain an integrated knowledge of content, pedagogy, and technologies that reflects new ways of teaching and learning in the 21st century. This interpretive study examined inservice K-8 teachers' growth in their pedagogical content knowledge (PCK) toward technology, pedagogy, and content knowledge (TPACK) in an online…

Describes an activity that demonstrates the use of the spreadsheet as a tool to handle lower level mathematics (computations), freeing students and teacher to focus on the higher level concepts in the problems. (SR)

Describes two general spreadsheet templates to carry out all types of one-equation chemical equilibrium calculations encountered by students in undergraduate chemistry courses. Algorithms, templates, macros, and representative examples are presented to illustrate the approach. (PR)

Presents an activity to integrate mathematics, science, and technology by using a computer spreadsheet to examine relationships between data collected about popcorn. (11 references) (Author/MKR)

Discussion of the use of computers in education focuses on ways to teach with limited computer resources. Learning processes with computers are described, the teacher-student relationship is examined, and examples of instruction using only one computer are given, including simulation programs in physics and the use of spreadsheets in mathematics.…

Describes how to place mathematical equations modeling population growth into a spreadsheet that performs calculations quickly and easily. Suggests experiments that can be performed with the spreadsheets. (WRM)

Presents integrated activities for mathematics and biology appropriate for various levels from grades five through eight. Explores interesting aspects of human fingernails and hair growth and their mathematical relationship to time. Provides suggestions to integrate the activities with technology. (MDH)

Problems ask students to calculate the pressure against a billboard in high winds and the velocity of water flowing from a reservoir through a cylindrical pipe. Problem solutions incorporate computer tools such as spreadsheets. (MDH)
