The course design has been paid attention to by both teachers and administrators. However, for a long time, some problems, such as the fragmented course design, and the repeated teaching contents, have existed in the college English curriculum for non- English majors from undergraduates, graduates and Ph. D students in the mainland China. Based on the ESP “learning-centred” approach, this study intends to construct an integrated curriculum system to help solve these problems through three main features of the integrated curriculum system: systematicness, hierarchy and openness. To investigate the feasibility of the course system, the combination of quantitative and qualitative research methods were used through questionnaire, text analysis and interview. The results show that, 1. This curriculum system can avoid the repetition of the course content. The fragmented curriculum design and the needs from the nation, society and students can be met through the systematicness, hierarchy and openness. 2. This system can facilitate teachers’ teaching reform and research interest because they have more choices to adapt the materials from students’ disciplines besides textbooks. This curriculum system is hoped to provide a possible way to meet the nation, society and students’ needs in the Chinese tertiary context.

CLIL (Content and Language Integrated Learning) incorporates content acquisition and language instruction, allowing students to develop linguistic competencies while engaging with particular topics. This research aims to investigate the effectiveness of CLIL activities in enhancing students' vocabulary, as well as to explore students’ views of engaging in CLIL activities for their learning process. The participants consisted of 21 primary school students with diverse levels of English ability. The study employed a mixed-methods research approach, combining a quasi-experimental study (one-group pre-test and post-test) with a survey. The results indicated that CLIL activities notably improved students’ vocabulary mastery, with post-test scores (Mean: 60,38) surpassing the average pre-test scores (Mean: 58,28). In response to the students' perceptions of their experiences, among 21 students, 15 (71%) indicated that CLIL activities enhanced their interest in English and science. In this study, CLIL activities were carried out by incorporating singing, engaging in games such as flashcards and QNA, and facilitating group discussions. The CLIL activities offer significant contexts for language application, facilitating the effective acquisition of new vocabulary for students. The students demonstrated enhanced vocabulary test scores as a result of the learning activities. The findings indicate that CLIL-based learning significantly enhances students’ vocabulary, and students express a favourable perception of this approach. Educators should incorporate CLIL activities into their instructional methods to create a vibrant and engaging learning environment. Future investigations could delve into the implementation of CLIL across various educational settings and disciplines to fully harness its potential advantages.
