The authors examined the effectiveness of a 2-year (kindergarten and first grade) oral English intervention provided to 534 Hispanic English-language learners in transitional bilingual education (TBE) and structured English immersion (SEI) programs. Using latent growth modeling, the authors compared instructional programs in relation to growth trajectories and rates in academic English oracy. The findings revealed that students in all four programs (treatment TBE, control TBE, treatment SEI, and control SEI) improved significantly ( p < .05) in a linear pattern over 2 years, and students receiving the intervention developed at a faster rate than those receiving typical instruction ( p < .05, effect sizes >0.46). The authors concluded that (a) first-language instruction did not impede the learning of a second language, and (b) enhancements and best practices in TBE and SEI programs are needed to accelerate oral English acquisition to remove the initial disadvantage of low levels of English proficiency.

The authors examined the impact of 2 subsequent, longitudinal interdisciplinary interventions for 58 Hispanic English language learners (ELLs): (a) Grade 5 science with English language/reading embedded (i.e., science intervention) and (b) K–3 English language/reading with science embedded (i.e., language/reading intervention). Results revealed that (a) in the science intervention treatment ELLs outperformed their counterparts in English-reading fluency, knowledge of word meaning, and science and reading achievement; (b) in the language/reading intervention treatment ELLs continued to develop faster than their peers in English oracy, reading fluency, and comprehension; (c) ELLs benefited more from the science intervention if they received the prior language/reading intervention. We conclude that for ELLs, the integration of science and English language/reading should primarily focus on reading in elementary grades and science in Grade 5.

This quantitative study examines current practice and challenges of Chinese–English bilingual education in Chinese tertiary institutions and presents a case study of a bilingual course by investigating learners' attitudes toward this educational and language policy. Using a convenience sampling strategy with an instrument modified from a nation-wide survey on bilingual education, this study involves 153 undergraduate science majors from a university located southeast of China. Results indicate that students held positive attitudes toward bilingual instruction and believed that such a model will not threaten the status of Chinese language and culture; and such an attitude significantly predicted students’ academic achievement whereas the level of English proficiency did not. Further, female students outscored their male counterparts in the final examination. Finally, the positive relationship between years of learning English and attitudes toward bilingualism corroborates with the current literature that earlier exposure results in additive bilingualism. We recommend future studies be conducted to identify the threshold for a minimal level of English skills commensurate with distribution of language of instruction so that college students can benefit from bilingual education. In conclusion, despite challenges, Chinese–English bilingual education is still expected to be a legitimate and eventually rewarding educational practice that fits the socio-political environment of developing China.

Through a quasi-experimental approach, we compared Chinese college students’ learning motivation, content knowledge, English language proficiency, and instructor’s pedagogical practices between an English-medium instruction (EMI) and the parallel Chinese-medium instruction (CMI) course in a non-traditional discipline. Results indicated that EMI was more effective, as compared to CMI, in motivating students’ learning of the focal subject. More specifically, EMI students held a stronger external goal orientation than did their CMI peers. Further, EMI and CMI students performed on par in their final exam in the subject and English after one semester of participation, controlling for their prior performance. The finding suggested that EMI did not carry a detrimental effect on Chinese college students’ content area learning. Finally, observation revealed a significantly higher percentage of English language instruction focused on higher-order dense cognitive area in the EMI classroom where students were more engaged in their learning. Implications for policy and research were discussed regarding this educational approach for sustained and optimized student learning.
