Development of Learning Achievement in Mathematics for Marine Engineering Using Scientific Calculators

Abstract

Development of learning achievement in mathematics for marine engineering using scientific calculators. It is Quasi–experimental research. The purposes of this research were to compare the learning achievement after using scientific calculators in the learning management with the 70% criterion and assess satisfaction. The samples consisted of 48 cadets enrolled in Mathematics for Marine Engineering 2 in the first semester of 2024 by use purposive sampling. The research instruments were course specification, an achievement test consists of Power Series, Approximate Integration and Newton-Raphson Method and satisfaction assessment. Researchers prepare the use of scientific calculators for the learners, conducted teaching, and demonstrated the use of scientific calculators in solving problems. The data were analyzed using mean, standard deviation, and Z-test. The research found that the score average learning achievement after learning management using scientific calculators calculated as 75.64 percent was significantly higher than 70 percent at 0.05 significant level, and overall satisfaction was at the highest level. Therefore, scientific calculators help improve learning achievement and make learners feel satisfied with learning mathematics.
