In this research report, we describe a study to map the scores of the TOEFL ® Essentials ™ test to the Canadian Language Benchmarks (CLB). The TOEFL Essentials test is a four-skills assessment of foundational English language skills and communication abilities in academic and general (daily life) contexts. At the time of writing this report, the test was the most recent addition to the TOEFL ® Family of Assessments. TOEFL Essentials test scores are intended to provide academic programs and other users with reliable information regarding the test taker's ability to understand and use English. Mapping of scores to widely used language frameworks such as the CLB provides additional support for interpreting test results and for making inferences regarding test-taker abilities. The score mapping process consisted of the following steps, as recommended in the literature: (a) establishing construct congruence between the test content and the performance descriptors of the CLB; (b) establishing recommended minimum test scores (cut scores) required to classify language learners into CLB levels, based on the judgments of local experts; and (c) providing evidence of procedural, internal, and external validation of the recommended cut scores.
As integrated writing tasks in large-scale and classroom-based writing assessments have risen in popularity, research studies have increasingly concentrated on providing validity evidence. Given the fact that most of these studies focus on adult second language learners rather than younger ones, this study examined the relationship between written discourse features, vocabulary support, and integrated listening-to-write scores for adolescent English learners. The participants of this study consisted of 198 Taiwanese high school students who completed two integrated listening-to-write tasks. Prior to each writing task, a list of key vocabulary was provided to aid the students’ comprehension of the listening passage. Their written products were coded and analyzed for measures of discourse features and vocabulary use, including complexity, accuracy, fluency, organization, vocabulary use ratio, and vocabulary use accuracy. We then adopted descriptive statistics and hierarchical linear regression analyses to investigate the extent to which such measures were predictive of integrated listening-to-write test scores. The results showed that fluency, organization, grammatical accuracy, and vocabulary use accuracy were significant predictors of the writing test scores. Moreover, the results revealed that providing vocabulary support may not necessarily jeopardize the validity of integrated listening-to-write tasks. The implications for research and test development were also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
