Most current statistics courses include some instruction relevant to causal inference. Whether this instruction is incorporated as material on randomized experiments or as an interpretation of associations measured by correlation or regression coefficients, the way in which this material is presented may have important implications for…

Emergentist, usage-based L2 research has witnessed that emphasizing formulaic sequences as entry points in meaning-based instructional contexts contributes to the development of linguistic comprehension and production. Related studies have thus far striven to find the most effective methods of highlighting these word strings. This study explored…

Learning chemistry vocabulary that has both scientific and everyday meanings, which we call dual meaning vocabulary (DMV), can be challenging for many students. This qualitative study investigated how college students understand 11 selected DMV words before and after traditional chemistry instruction and to what extent they retain the scientific…

Documenting how students with learning disabilities (LD) initially conceive of fractional quantities, and how their understandings may align with or differ from students with mathematics difficulties, is necessary to guide development of assessments and interventions that attach to unique ways of thinking or inherent difficulties these students…

This multiple case study investigated how college students with diverse ethno-linguistic backgrounds used chemistry vocabulary as a way to look at their discursive identities and cultural border crossings during first semester general chemistry laboratories. The data were collected in two major forms: video-taped laboratory observations and…

This study compared traditional and distance education delivery platforms (onsite, hybrid, and online) at the college level in an urban setting in terms of student success, measured by final course grades and identified predictors of student success. The study examined the role of variables (prior knowledge of mathematics, language, gender,…

Studies from information-processing and language comprehension research have reported that background knowledge facilitates reading and writing. By comparing Chinese language development of heritage students who had home background in Chinese language and culture with those who did not, this study found that heritage learners did significantly…
