This study highlights the significance of the integration of implicit-explicit vocabulary instruction, project-based learning (PBL), multimedia, and experiential learning to improve Thai EFL senior high school students' vocabulary ability. It aimed to investigate to what extent the integration affected Thai EFL senior high school students' vocabulary ability and how their perceptions toward the instruction were. The study involved 45 tenth-grade students at a public high school in Bangkok, Thailand. A vocabulary pre-and post-test was used to evaluate the students' vocabulary ability before and after the application of the integrated instruction. Additionally, students' reflective journals (SRJ), a students' perception questionnaire, and a semi-structured focus group interview provided qualitative data for analyzing the students' perceptions toward the instruction. The findings revealed that all students' test scores significantly improved and confirmed the effectiveness of the integrated instruction on vocabulary learning. All of the 45 students also reported positive perceptions toward the instruction. They reflected that the instruction was advantageous and practical since it facilitated their vocabulary learning, increased their selfconfidence and improved their speaking skills. It also created a pleasant learning atmosphere, provided the students with more opportunities to participate in classroom activities, and encouraged the students to learn with technology.

The growth of Thailand’s medical tourism industry has inevitably made English oral communication skills become increasingly important to Thai medical personnel, especially to nurses who have to act as medical mediators between doctors and patients. Thus, in order to prepare nursing students for their future career, it is necessary that English teachers find a way to help students improve their oral communication ability. Thus, in this study, as a means to overcome the students’ difficulties in learning English and to enhance their English oral communication ability, the task-based instruction using a digital game in a flipped learning environment (TGF) was developed by integrating three language learning approaches, namely task-based language teaching, flipped learning, and digital game-based language learning. The development of the instructional framework for the TGF was described first. Then, to investigate its effectiveness in improving the students’ oral communication ability, an experimental study, using a one-group pretest posttest design, was conducted with 23 second-year nursing students at a private university in Thailand for 11 weeks. The effects of the TGF on the students’ oral communication ability were assessed by the participants’ pre- and post-test. The finding revealed that the participants’ average post-test score was statistically significantly higher than their average pre-test score (p < 0.05), indicating that the TGF was successful in enhancing the students’ oral communication ability. Lastly, the factors contributing to this success were discussed.

With the rising interest in the Intercultural Communicative Competence (ICC) in language teaching, evaluating the ICC attributes in EFL textbooks is becoming a great concern. This study aimed to find out the evaluation criteria for the ICC attributes in EFL textbooks generated from the literature and from EFL experts, and then construct an evaluation checklist for assessing the ICC attributes of the English majors' textbook in China. The findings revealed that thirty-six items were identified from the literature and another thirty-six new items were generated from the interview with nine experts in the fields of ICC research and textbook selection. These items were constructed into a draft checklist and checklist was validated by another nine EFL teachers and native-speaker teachers. Consequently, a try-out checklist with two dimensions, eight themes and sixty-one items was developed. Given the vital role of ICC in English teaching, it is essential to understand the ICC attributes in EFL textbooks, which is a relatively new construct. The proposed checklist was a critical step towards a better evaluation of ICC attributes in English majors' textbooks and would be a helpful tool for teachers in textbook evaluation. Future research is required to refine the try-out checklist.

Lesson planning employs both pedagogical and content knowledge. The processes are complex and student teachers, undergoing practicum, struggle to plan. However, studies that explain processes drawn from a qualitative inquiry to explain the practice are rare. The purpose of this study is to generate a theory to explain Thai EFL student teachers' lesson planning by adopting the grounded theory. The research questions include 1) How do the Thai EFL student teachers design their lesson plans? 2) How do the student teachers implement the lesson plans? and 3) What action do the student teachers take after implementing the lesson plans? The research instruments are semi-structured interviews as well as observations of 22 student teachers majoring in Teaching English. The data is analyzed by means of coding to identify emerging categories and generate a substantive theory. A constant comparative analysis of the data generates a grounded theory of EFL student teachers' lesson planning, illustrating cyclical processes of four stages. The first stage is pre-planning, where personnel and institutions have an influence by giving information necessary for planning. The second stage is planning, showing both linear and non-linear processes. The third stage is implementing plans, observed by school and university supervisors. Student teachers agree, partly disagree or entirely disagree with feedback and use or do not use the feedback to improve subsequent plans. Finally, the last stage is reflecting/evaluating, showing modes of communication and a reflective process for both problems and success.
