# INSTRUCTIONAL ACTIVITY ON LIMITS AND CONTINUITY OF A FUNCTION BY USING A GRAPHING CALCULATOR FOR UNDERGRADUATES

## Main Article Content

## Abstract

The researchers had constructed the instructional activity on limits and continuity of a function by using a graphing calculator to enhance understanding levels of mathematical conceptual on limits and continuity of a function based on APOS theory and students’ satisfaction after used our constructed activity. Students would understand the concept of convergence of a function by observed left and right limit of a function conducted by a graphing calculator. The study was conducted during the first semester of the 2021 academic year with undergraduates of the Department of Logistics Management, Thepsatri Rajabhat University. The experiment group with 60 students was using the cluster random sampling approach. The researchers taught the group for three periods of 180 minutes each. Final achievement on limits and continuity of a function test were used to assess the undergraduates’ performance. Moreover, the selected sample was given a questionnaire to measure his/her satisfaction toward instructional activity. The results of the study were as follows: 1) The effectiveness of the instructional activity on the limits and continuity of a function by using a graphing calculator for undergraduates were 87.28/82.66, which is higher than the criteria of 80/80. 2) Limits and continuity of a function showed that the mean score of the action level was 16.45, the process level was 11.02, and the object level was 9.11, where the total marks are 20, 15, and 15, respectively. 3) The satisfaction toward the instructional activity on limits and continuity of a function by using a graphing calculator achieved a high score.
