The study aimed at investigating the effects of peer feedback on students' English writing ability in L2 writing class. A mixed-methods research, an embedded experimental design was employed, making use of a writing pretest and post-test and self-written reflection in the experiment. Data were quantitatively analyzed through a dependent simple t-test, and content was thematically analyzed for qualitative data. The participants were 21 undergraduate students majoring in English in the three southernmost border provinces of Thailand. The findings revealed that from the mean scores of the pretest and post-test, the students had made significant progress in their writing ability. Additionally, the effect size was calculated at 1.97, which means that its magnitude was "large". Moreover, students reflected that peer feedback was a worthwhile experience for social interaction, and provided them with perceiving the writing process, developing affective strategies, supporting critical thinking skills, and developing socially and intellectually by means of working collaboratively. In addition, it helped them practice to become more autonomous learners. As a result, peer feedback should be implemented in L2 writing classes.

The study investigated students’ patterns of interaction and their viewpoints toward incorporating peer feedback in L2 writing class, making use of a video stimulated recall (VSR) interview and the compositions. Data were analyzed qualitatively; two groups of six students with mixed English proficiency were analyzed in terms of the language-related episodes (LREs). The participants of the study were 21 undergraduate students, majoring in English in a university in the three southernmost border provinces of Thailand. For data analysis, peer dialogues were recoded, transcribed and coded to identify students’ patterns of interactions in terms of collaborative, expert/novice, dominant/dominant and dominant/passive patterns, based on Storch’s (2002) scheme. Moreover, the findings revealed that the students’ English proficiency level did not influence the LREs and their writing ability. Additionally, students’ writing performance was improved in the identified patterns of the collaborative and expert/novice instances. Specifically, students perceived the writing process, developed affective strategies, reinforced their critical thinking ability and enhanced their social interaction skills.  Besides, it encouraged them to become more effectively autonomous learners. Hence, peer feedback should be implemented in L2 writing.

This study aimed at exploring students’ attitudes toward peer feedback to develop their English writing ability. A mixed methods research, an embedded experimental design, was adopted to elicit students’ viewpoints toward peer feedback making use of five-point Likert scale questionnaires comprising 36 statements and six open-ended questions, which were conducted to 21 undergraduate students majoring in English in one university in the three Southern border provinces of Thailand. For the data analysis, A paired samples t-test was quantitatively analyzed, wherereas content themantic analysis was adopted for qualitative data. The overall findings illustrated that the students had a positive attitude toward using peer feedback that achieved a high level in four domains in terms of the writing process, affective strategies, critical thinking skills and social interaction ability. From the result, it could also be seen that students understood about the writing strategy and were able to conduct peer feedback process more effectively, produced improved writing performance with better grammar structure. Additionally, discussing by peers evevated critical thinking skills and developed social skills through working collaboratively. Importantly, peer feedback process supports a student-centered approach and allows students to become more autonomous learners in writing. Consequently, peer feedback should be taken into consideration in the curricula of L2 writing.

The pilot study aimed to investigate students’ English writing ability via online peer feedback during covid-19 pandemic. In this pilot study, eight open-ended questions, which were conducted to 12 undergraduate students majoring in English with mixed grades coming from 43 students in English writing class in one university in the three Southern border provinces of Thailand. The data analysis stage made use of qualitative data to conduct thematic analysis of the content. The results indicated that students took a positive view of using online peer feedback to support the development of their writing, since this feedback also upgraded their affective strategies and critical thinking skills as well as their ability to interact socially in an effective manner. The results indicate student perceptions concerning writing strategies and found that they believed that online peer feedback could be carried out effectively, leading to improvements in their writing through enhanced grammatical usage. Furthermore, peer feedback and discussions supported better critical thinking skills as well as improving social skills through the need to work cooperatively. Importantly, the pilot study is very beneficial to both instructor and students, especially the instructor can bring to adapt the main study more effectively. Therefore, the findings of online peer feedback ought to be taken into consideration in the main study group to adapt in learning and teaching process.
