Second language acquisition

Community colleges provide open access and affordable options for higher education to a growing population of adult English Language Learners (ELLs) in the United States. Language minority groups, particularly native Spanish speakers, are currently the fastest growing demographic in the nation. Community college English as a Second Language (ESL) courses constitute a vital support for these students by providing adult ELL students with foundational college literacy skills. With the growing demand for college graduates in today's workforce, language minority students, like their native English-speaking (NES) counterparts, need to leave college with vendible work credentials. Community colleges need practical and affordable ways to improve learning and degree completion rates of their English language learners. College ESL programs face two key challenges in realizing this goal: (1) providing quality language preparation for college-bound E LLs, and (2) developing efficient ways to deliver curricula to a student population that has limited financial resources and time. This was a single institution case study that investigated two ESL curriculum models at a large urban community college. The study compared the academic performance and persistence of ELL students who studied in a sheltered ESL curriculum to ELL students who studied in a concurrent enrollment ESL curriculum that combined college-level courses with advanced ESL study. The researcher analyzed student data from college archives: transcript data, admission data, and course performance results. Data from three student groups were salient to the study -- students in concurrent enrollment courses (partially-mainstreamed ESL students), students in traditional ESL courses (not mainstreamed), and native English speakers in freshmen-level general education courses. The study described the relationship between the two types of ESL curriculum and the academic performance and persistence of ELL students in each program. Findings showed that advanced ELL students were able to successfully complete select college courses as they finished their ESL program. Results indicated that early access to college courses motivated students to persist. This study can help ESL practitioners and administrators in higher education determine if a concurrent enrollment curriculum model is a viable alternative for intermediate and advanced level ELL students.

Bilingual children sometimes respond to their interlocutors using a different language than the one in which they were addressed. These language choices, their concurrent correlates, and relations to subsequent language growth were examined in 91 Spanish-English bilingual children (44 girls, 47 boys). Children's language choices were assessed at 30 months, and their English and Spanish productive vocabularies and receptive language skills were examined at the ages of 30, 36, and 42 months. Children's language choices were concurrently related to English and Spanish productive and receptive language scores and to mothers' English and Spanish proficiency levels. Longitudinal multi-level modeling analyses indicated that children's language choices at 30 months were uniquely related to language growth on measures of English and Spanish productive vocabulary and Spanish receptive language, when controlling for language expo sure. These findings suggest that language use plays a causal role in language development. The findings of this study have implications for the maintenance of heritage languages in the U.S. and for the development of children's English language skills.

This qualitative case study was conducted to investigated whether selected 3rd-5th
teachers in a Title 1 school increased their understanding as they described and used their
pedagogical Content Knowledge (PCK) in writing aligned with the Common Core
Anchor Standards 1-6. It also examined how the teachers collaborated to advance their
knowledge in the area of ELs in the classroom. Qualitative data were collected in the
form of 15 participant interviews and 15 Learning Team Meeting (LTM) observations.
The data from the interviews and observations were used to investigate how participants
implemented the Common Core Anchor Standards (CCAS) 1-6 in their classrooms. The
data also sought to examine how the participants’ collaboration in LTMs contributed to
the selected 3rd-5th grade teachers’ PCK with respect to CCAS 1-6 and support for their
English language learners (EL). The findings indicated that participants recognized various EL instructional strategies embedded in the subject matter of writing. Further, the data indicated that the dual language participants collaborated as an effective means for delivering various EL instructional strategies.
