Maximising students’ exposure to English through varied cross-curricular approaches Language Learning Support Section EDB
Why is vocabulary teaching so important? • Research shows that vocabulary knowledge • Is related to a student’s ability to comprehend text (Beck et al., 1987 Baker et al., 1995, Graves, 2000) • Is related to academic success (Saville-Troike, 1984)
Traditional vocabulary teaching practices in subject classrooms Dictionary Dictation
Why isn’t it effective? • Dictionary alone is not the answer because: • Definitions in the dictionary are not student friendly
Example 1 Osmosis • Osmosis is the distribution of liquid with a low concentration flowing through a membrane into an area with a higher concentration resulting in the concentrations being equal on both sides • (Your Dictionary)
Example 2 Opportunity Cost ??? cost in terms of foregoing alternatives (The Free Dictionary) 機會成本
Why isn’t it effective? • Frequent dictation without using the words will only lead to rote learning. • Researchers point out that a student learns a word through repeated exposures. The number of exposures is between 10-12. (Beck et al, 2002) Need active student involvement in connecting the new meaning/word to the existing knowledge base.
Effective vocabulary instructional program Teachers must: Teach word learning strategies Teach words Provide extensive experiences with language Establish a word conscious environment M. Graves, 2000
