With English-medium instruction (EMI) as a pedagogical strategy being practiced worldwide in higher education (HE), extensive research has explored stakeholders’ attitudes toward, and perceived benefits and challenges of EMI based on self-report data. However, the actual effectiveness of EMI on students’ subject content and English language learning achievements tested with objective measures has accrued little evidence. This meta-analysis synthesized 44 independent samples (32 in medical disciplines) from 36 studies. The results show that EMI students performed significantly better in both subject content and English learning than students in Chinese-medium courses, but it should be noted that the difference in content learning was found only with students from medical disciplines. Discipline was the only significant factor moderating content learning, while disciplines, research design, and instruction time in English significantly moderated English learning. The findings provide implications for implementing EMI in similar contexts and highlight the importance of rigorous future research to examine the benefits of EMI.
Some proponents of higher education English as a medium of instruction (EMI) have suggested listening to English lectures provides students the opportunity to incidentally acquire unknown words. A case study was designed to examine this assumption. First, the lexical profiles of 27 Introduction to English Language Teaching first-year undergraduate course lectures were computed to determine how many words students need to know for comprehension. Then an incoming year-1 undergraduate student with an English vocabulary size of 7,500 word families and mastery of the most frequent 3,000 word families listened to these lectures across 13.5 weeks with the purpose of measuring incidental acquisition gains of three aspects of word knowledge for ten targeted words. Lastly, the student’s perceptions about listening to EMI lectures and potentials for this listening inducing incidental acquisition of word knowledge were gathered through a semi-structured interview. The lexical profiling of the entire corpus showed students need knowledge of the most frequent 4,000 English word families plus proper nouns and marginal words for 98% lexical coverage; however, some lectures present students with a more substantial lexical burden than the lectures overall. The student made the most gains in receptive meaning, followed by receptive form, and finally productive meaning. Content analysis of the interview transcript found seven themes representing the student’s perception about listening to EMI lectures and their potential for inducing incidental vocabulary acquisition. While the student found listening to the EMI lectures challenging, he perceived the process as useful in preparing for university studies and a career as a secondary English teacher. The student perceived attention, topic, existing vocabulary knowledge, lecturer’s native language, and lack of interaction with the lecturer to have moderated incidental learning of vocabulary through listening to English lectures. These results indicate a need to confirm whether incoming students’ vocabulary knowledge meet the lexical demands of the EMI lectures given in the Macau context. Furthermore, pedagogical training on teacher talk strategies and orientation training for incoming students should both be provided to ensure students are receiving high quality instruction.
Since the official implementation of the One-Child Policy in 1980, China has achieved remarkable results. With the intensification of the population aging phenomenon, the economic pressure caused by the serious inconsistency between the current economic level and the population growth rate cannot be ignored, and the ratio of male and female is seriously imbalanced. In this paper, using the 2013 and 2015 China General Social Survey (CGSS) data. From a micro perspective, using the Logit model to find the impact of China's implementation of the Two-Child Policy on the fertility rate. This paper finds 3 important conclusions: (1) individual socio-economic characteristics and Two-Child Policy have significant influence on women's fertility level; (2) The implementation of the Two-Child Policy has not shown a boost to China's overall fertility in the short term. The fertility policy is not enough for China's current situation; (3) more policies should be introduced to ensure the care and education of newborns in order to reduce the "cost" of rising a child.
