RESUMEN
Federal funding agencies have invested significant resources supporting evidence-based, innovative approaches that address education problems and incorporate rigorous design and evaluation, particularly through randomized controlled trials (RCTs), the gold standard for yielding causal inference in scientific research. In this study, we introduced factors (i.e., evaluation design, attrition, outcome measures, analytic approach, and fidelity of implementation) that are often times required in the Federal Notice for application by the U.S. Department of Education, with an emphasis on What Works Clearinghouse (WWC) standards. We further presented a federally funded research protocol with a multi-year, clustered RCT design to determine the impact of an instructional intervention on students' academic performance in high-needs schools. In the protocol, we elaborated on how our research design, evaluation plan, power analysis, as well as confirmatory research questions and analytical approaches were aligned with the grant requirement and WWC standards. We intend to provide a road map to meeting WWC standards and to increase the likelihood of successful grant applications.

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.
