The purpose of this study is to examine the relationships among English learners’ motivation, strategies, and achievement. The participants were 61 Korean college students specializing in Aviaition Service and they took a mock TOEIC and completed a questionnaire on learning motivations and strategies. T-test and multiple regression analysis were used to determine the relationships among all variables. The findings revealed that, first, variables in integrative motivation were found to be a statistically significant predictor of achievement while variables in instrumental motivation’ was higher order motivation type. Second, participants used ‘compensation strategies’ most frequently and higher-achieving students used more strategies than their peers did. ‘Metacognitive strategies’ and ‘affective strategies’ had statistically significant impacts on their achievement. In conclusion, the relationships among learning motivation, strategies and achievement was found to be definite. Implications for more effective study habits are suggested.

Positional clonging (map-based cloning) of mutations or genetic variations has been served as an invaluable tool to understand in-vivo functions of genes and to identify molecular components underlying phenotypes of interest. Mice homozygous for the cerebellar deficient folia (cdf) mutation are ataxic, with cerebellar hypoplasia and abnormal lobulation of the cerebellum. In the cdf mutant cerebellum approximately 40% of Purkinje cells are ectopically located within the white matter and the inner granule cell layer (IGL). To identify the cdf gene, a high-resolution genetic map for the cdf-gene-encompassing region was constructed using 1997 F2 mice generated from C3H/HeSnJ-cdf/cdf and CAST/Ei intercross. The cdf gene showed complete linkage disequilibrium with three tightly linked markers D6Mit208, D6Mit359, and D6Mit225. A contig using YAC, BAC, and P1 clones was constructed for the cdf critical region to identify the gene. A deletion in the cdf critical region on chromosome 6 that removes approximately 150 kb of DNA selection. cdf mutant mice with the transgenic copy of the identified gene restored the brain abnormalities of the mutant mice. The positional cloning of cdf gene provides a good example showing the identification of a gene could lead to finding a new component of important molecular pathways.
