A Study of Learning Achievement and Self-efficacy in Mathematics on Factorization of Second Degree Polynomials Using ACE Learning Management and Exit Tickets

The objectives of this research were 1) to compare mathematics learning achievement
and self-efficacy in mathematics after using ACE learning management and Exit tickets
with the criteria, and 2) to study the relationship between mathematics learning achievement
and self-efficacy in mathematics after using ACE learning management and Exit tickets.
The target group consisted of 36 Matthayom Suksa 2 students during the second semester
of the academic year 2021 at Taweethapisek School. The research instruments consisted
of lesson plans using ACE learning management and Exit tickets, the mathematics learning
achievement test, and the mathematics self-efficacy questionnaire. The data were analyzed
using mean, percentage, and Pearson's correlation. The results showed that 1) after using ACE
learning management and Exit tickets, more than 70 percent of students demonstrated
achievement in mathematics on the factorization of second-degree polynomials above the 80
percent threshold and more than 60 percent of students achieved their mathematics self-efficacy scores above the threshold of 70 percent, and 2) the mathematics learning
achievement and mathematics self-efficacy were highly positively correlated at the .01 levels
of significance.
