A development of learning achievement of 10th grade students with a computer assisted instruction (CAI) on stoichiometry

Abstract

The development of computer-assisted instruction (CAI) represents a valuable choice for enhancing education in an era where technology plays a pivotal role in learning. This research aimed to achieve the following objectives: 1) to determine the efficiency of the CAI titled “Chemical Reaction and Equation” based on the 7 0/ 7 0 criterion 2) to compare academic achievement and learning progress between the control and experimental groups and 3) to study satisfaction levels following learning through the CAI. The samples comprised 40 tenth-grade students, with 20 students each in the control and experimental groups, selected from Tha-Makham Wittaya School in Ratchaburi Province during the first semester of 2023 using purposive sampling. The research tools consisted of the following: 1) the CAI titled “Chemical Reaction and Equation” with an Index of Concordance (IOC) ranging between 0.67-1.00 2) the learning management plan of the CAI with IOC between 0.67-1 .00 3) the 5-level satisfaction questionnaire with IOC of 1 .00 and 4) a test designed to assess an academic achievement, with levels of internal consistency indicated by KR-20 of 0.70, including difficulty values ranging between .50 and .80 and discrimination levels ranging between0.25- 0.62. The results of this research revealed that 1. The CAI demonstrated an efficiency value (E1 /E2 ) of (90.75/75.75). 2. In term of academic achievement, the experimental group had a higher number of students who passed the 70% criterion compared to the control group. The learning progress of the experiment group reached moderate and high levels (70% and 30%, respectively), while that of the control group varied among moderate, high and low levels (65%, 25% and 10%, respectively). 3. Satisfaction with the CAI was at a high level (x̅ = 4.04, SD = 0.66).
