In this study, we described and compared an English as a foreign language (EFL) teacher’s pedagogical behaviors in traditional and problem-based learning (PBL) classroom settings in a Chinese university. In spring 2019, we collected six 45-min videos, three in each condition, covering three modules: (a) warm-up and vocabulary, (b) essay structure, and (c) writing. The analyses of the teacher’s pedagogical behaviors and her interaction with students indicated that the instructor spent most of the instructional time delivering higher-order thinking content in both traditional and PBL classes. The teacher’s activity structure influenced students’ communication mode. Although the instructor provided students with more group discussion activities in the PBL classroom, lecturing was observed to be the primary delivery method in both classes. These results suggest that the application of PBL strategies in the EFL classroom did not significantly restructure the teacher’s pedagogical behaviors, and thus, failed to achieve the goal of providing students with more opportunities for improving their expressive English language proficiency. These findings underscore the need to develop an effective PBL-related curriculum and professional development opportunities for EFL teachers to effectively implement the PBL approach in the classroom.

This study compares the science achievement growth trajectories of fifth-grade students in rural and nonrural school districts in Texas. Using a growth hierarchical linear model, we explored the effects of time, school location (rural vs. nonrural), and their interaction on students’ science performance as measured by the high-stakes State of Texas Assessment of Academic Readiness (STAAR) science test over five academic years. We found that rural school students lagged in science at the initial stage when STAAR was first administered in the 2011–2012 school year. With time, the gap between rural and nonrural district students’ science performance persisted. We further added eight district-level factors that might influence students’ academic performance into the model and found that three variables (i.e., student mobility rate, percentage of students identified ELs, and teacher turnover rate) constantly influenced students’ science scores. The implications for teaching pedagogy and research are discussed regarding science education in Texas rural districts.

Abstract:The overarching purpose of our study was to compare performances of treatment and control condition students who completed a literacy-infused, inquiry-based science intervention through sixth grade as measured by a big idea assessment tool which we refer to as the Big Ideas in Science Assessment (BISA). First, we determine the concurrent validity of the BISA; second, we investigate the differences in the post-test of the BISA between treatment and control English Learners (ELs), controlling for their performance in the pre-test; third, we analyze the differences in the post-test of the BISA between treatment and control non-ELs, controlling for their performance in the pre-test; and fourth, we examine the relationship between students' English language proficiency as measured by standardized assessment, and their performance in the BISA among ELs and non-ELs, respectively. Our findings indicate: (a) literacy-infused science lessons with big ideas, implemented through the tested intervention, improved students' language acquisition and science concept understanding for ELs and economically challenged students (ECs); (b) there was a positive relationship between language and content for both ELs and non-ELs, with a similar magnitude, suggesting that students with a higher level of English proficiency score higher in science assessment; and (c) the lesson plans prepared were successful for promoting a literacy-infused science curriculum via a 5E Model (Engage, Explore, Explain, Elaborate, and Evaluate) that includes three to five of the Es used daily. A pedagogical approach for a literacy-infused science model with big ideas is proposed.
