INTRODUCTION 1.1 Rationale for the study The English language has a remarkable history In historical records, it was the speech of some tribes on the continent of Europe along the North Sea (Algeo & Butcher, 2013) As centuries went by, English has become the most widespread language in the world English is used by many peoples for more purposes than any other language on Earth, so it is necessary to teach, learn, and study this language in contemporary society In Vietnam, English has become the most popular foreign language since 1986 At that time, the Vietnamese Communist Party initiated its overall economic reform and implemented the open-door policy that helped the English language gain its popularity As the ability to communicate in English could open business opportunities for people in Vietnam, English has been taught at all levels of education across the country According to “Chương trình giáo dục phổ thông môn tiếng Anh” (English language curriculum for Vietnamese) issued by the Ministry of Education and Training (2018), the English language curriculum set its aim of helping Vietnamese students to develop English communicative competence through improving macro-skills (listening, speaking, reading, and writing) and micro-skills (pronunciation, vocabulary, and grammar) (p 3) After completing the English language curriculum at the upper-secondary level, Vietnamese students can: - use English as a tool to talk about familiar topics such as schools, recreational activities, jobs - develop basic knowledge of the English language, including pronunciation, grammar, and vocabulary, and understand people and culture of foreign countries, respect the cultural diversity, and present the value of Vietnamese culture in English - use English to improve the learning quality of other subjects in the curriculum at the upper-secondary level - use English to pursue higher learning targets or to undertake some work after completing the curriculum at the upper-secondary level - apply different learning methods to manage a learning schedule, use information and technology for learning and self-study, take responsibility for learning results, and shape lifelong learning (p 7) In “Tài liệu hướng dẫn dạy học theo Chương trình giáo dục phổ thơng mới” (Teacher guide according to English language curriculum for Vietnamese) issued by Ministry of Education and Training (2018), projects are referred to as effective activities in foreign language teaching because projects can support studentcentered approach and promote learner autonomy, collaborative learning, and taskbased learning (p 69) Therefore, in the current English textbooks published by Vietnam Education Publishing House in collaboration with Pearson Education, projects are considered an element in helping students to achieve the aim set by the English language curriculum for Vietnamese (2018) In those English textbooks, projects lie at the end of each unit, allowing students to a survey or research on a topic and then present the results in class The English language curriculum for Vietnamese (2018) also stated that assessment played an essential role in gathering information about students’ English communicative competence during and at the end of a learning period, which increased learner motivation and helped students to direct their learning and assisted teachers and school managers in making judgments about students’ learning Assessment can be carried out in many forms, such as teachers can assess students, teachers can have students assess other students or teachers have students assess themselves (p 50) In this sense, assessment is not only about giving students grades but also about helping teachers and students to improve the teaching and learning quality in English classrooms As projects and assessment are critical to assisting teachers and students in achieving the aim set by the English language curriculum for Vietnamese (2018), it is worth conducting a study on teachers’ assessment of students’ projects in the English classrooms However, the study only focuses on the following aspects: APPENDICES APPENDIX A: QUESTIONNAIRE FOR THE

VIII ① ② ③ ④ ⑤ APPENDIX C: TEACHER INTERVIEW SCRIPT SAMPLE Question 1: Why you assess students’ projects? Teacher D: “I assess students’ projects to provide information to parents I often send students’ projects through short videos and photos to parents at teacher-parent meetings and give my comments on students’ learning in class The parents really want to know what and how their children learn English at school.” Teacher A: “I assess students’ projects to support their independence in learning Students are often required to projects in groups, which means they had to solve a lot of problems from ideas to schedule They manage everthing by themselves to complete their projects, so projects are exploited to support students’ independence in learning.” Question 2: What criteria you use for assessing students’ projects? Teacher A: “I not pay close attention to students’ grammar when students speak English They have time to prepare an English script beforehand, so they can check grammar mistakes by themselves or have their peers correct the grammar Thus, I notice very few grammar mistakes when assessing their projects.” Teacher E: “When I follow my students’ presentations, I am often interrupted by the students’ mispronunciations They produce many English words incorrectly and this prevents me from understanding the content of their presentations I think pronunciation is the first aspect when I assess students’ projects.” IX APPENDIX D: STUDENT INTERVIEW SCRIPT SAMPLE Question 1: Why does your teacher assess projects? Student E: “I think the teacher wanted us to speak English because the projects required us to give presentations.” Student A: “My teacher said we had learned English for several years but still found it hard to communicate in English Therefore, projects would be an effective way for us to practice speaking English.” Question 2: What are some benefits of your teachers’ project assessment? Student D: “My teacher pointed out my mispronunciations and helped me to correct them Therefore, I have made a lot of progress on pronunciation I also learned to use Google Docs and Google Slides, which came in handy for sharing and revising materials in groups.” Question 3: What are some drawbacks of your teachers’ project assessment? Student E: “I found it hard to understand the assessment criteria because they are something abstract But after I watched my peers’ performance and listened to my teacher’s feedback for them, things became clearer and I had a better understanding of the assessment criteria We had to the projects by ourselves, so the teacher did not ask us if we had any difficulties in completing the projects.” X APPENDIX E: DOCUMENT SAMPLE Analytic rubric PHIẾU ĐÁNH GIÁ PROJECT STT Tiêu chí Điểm Chuẩn bị: - Học sinh chuẩn bị project phù hợp với yêu cầu, có sử dụng phương thức minh họa: …/2 Tranh ảnh, PPT, Kịch, … Nội dung: - Nội dung phù hợp với yêu cầu đưa …/4 - Sử dụng ngơn ngữ xác Thuyết trình: - Phong cách thuyết trình hợp lý …/3 - Các thành viên thuyết trình Thời gian: - Thời gian thuyết trình đảm bảo thời gian từ …/1 13 đến 15 phút Tổng …/10 Analytic rubric Video: Home Master chef CATEGORY Video Content Students All students Most students Most students showed showed showed excellent needed note cards excellent excellent knowledge of to talk knowledge of knowledge of content, but 1-2 XI content, content, but 1- often needed note needing no students cues and once needed showing no note cards to hesitation in talk cards to talk talking Videography Clarity Video did not Video did not Video had a little Problems with rock/shake rock/shake rocking/shaking, rocking/shaking and the focus and the focus but the focus was AND focus was excellent was excellent excellent throughout for the throughout majority of the video Length of Video was Video was Video was 50 Video was less minutes long 1.50 or 2.50 seconds or than 50 seconds minutes long minutes long or more than Video o Vocabulary minutes long Uses Uses Uses vocabulary Uses vocabulary vocabulary vocabulary appropriate for the appropriate for the appropriate appropriate audience Use at audience Use at for the for the least 6-9 verbs least under verbs audience Use audience Use related to cooking related to cooking at least 15 at least 10-14 in the book in the book verbs related verbs related to cooking in to cooking in the book the book Total score: _16 Analytic rubric XII Project Evaluation Criteria Points Comments Presentation Time Did the talk run /5 over or under?
