In language assessment, I examine the validity of large-scale proficiency test score interpretations and uses as well as the qualities and usefulness of &#8216;smaller&#8217; tests, such as local placement exams and instructionally-relevant diagnostic tests. In instructed second language acquisition, much of my work has involved the development of L2 pronunciation and language learning via technology. Although not exclusively, I do primarily quantitative research and have taken an interest in quantitative methodology in L2 research, with an emphasis on research ethics.<\/p>\n<p><b>Areas of Expertise<\/b><\/p>\n<ul>\n<li aria-level=\"1\">language testing and assessment<\/li>\n<li aria-level=\"1\">second language pronunciation<\/li>\n<li aria-level=\"1\">instructed second language acquisition<\/li>\n<li aria-level=\"1\">technology in language learning<\/li>\n<li aria-level=\"1\">quantitative research methods<\/li>\n<\/ul>\n<p><b>Selected Publications<\/b><\/p>\n<p><b>Isbell, D.<\/b>, &amp; Kim, J.
