The Development of a Web-Based Instructional Model to Enhance Vocabulary Learning Ability Through Context-Clues Based Meaning Guessing Techique : "The Saitakham Model"
Abstract
The present study aims to develop a web-based instructional model for enhancing English vocabulary learning ability by context-clues based meaning guessing technique, determine the efficiency of English vocabulary learning lessons via web-based instruction (WBI) based on the 85/85 (Brahmawong, 1978) and to compare achievement of English vocabulary learning ability of both experimental group and control group. The samples were 80 students who enrolled in the English III course in the trimester 1, academic year 2010 at Suranaree University of Technology. They were divided into two groups: the experimental group received tutoring to enhance English vocabulary learning ability by context-clues based meaning guessing technique via the web-based instruction (www.welmc.net) while the control group received tutoring from face to face method. After taking a pre-test, the experimental group was taught via the web-based instruction and the control group was taught by face to face method. When finished learning, both groups were asked to do a post-test.
The 85/85 standard criterion was used to determine the efficiency of English vocabulary learning lessons via web-based instruction by using the efficiency of the process and the efficiency of the product formula (E1/E2 formula). To compare the English vocabulary learning achievement both of the control and experimental groups, the Analysis of Covariance or ANCOVA was used to remove extraneous variability that derives from pre-existing individual differences. This study found that the web-based instructional model (The Saitakham Model) for enhancing English vocabulary learning ability by guessing meanings from the context clues was rated by the experts in Instructional System Design and English Language Teaching field as "Very Appropriate" (x̄ = 4.67), the efficiency value of the development of a web-based instruction lessons to enhance English vocabulary learning ability by guessing meanings from the context clues are 83.50/84.25 which is higher than the standard level at 80/80, and the achievement of English vocabulary learning ability of the students in the experimental group was higher than that of the students in the control group with statistically significant differences at 0.05
