Metadiscourse is an essential component of academic writing, as it helps authors better communicate their ideas and engage their readers. It is through the analysis of the text's metadiscourse that one can explore academic writing and compare the rhetorical traits and preferences of various discourse communities (Hyland, 2005). To this end, this study examined the differences in the use, type, and frequency of interactional metadiscourse markers in the discussion and conclusion sections of political science and religious studies articles written in English language. The corpus of this study consisted of 45032 words extracted from fifty research articles, twenty-five articles in the field of political science, and twenty-five articles in the field of religious studies published between 2019 and 2023 in the top one high-impact factor and peer-reviewed international journals. To analyze the data, one Eta and two Chi-square tests were run. Considering the interactional resources of Hyland’s (2005) metadiscourse model, the researchers uncovered that despite some subtle differences in the use, frequency, and types of these metadiscourse markers, “hedges” were the most and attitude markers were the least frequently used metadiscourse markers employed in both political science and religious studies disciplines. The findings have some educational implications that shed light on the need to encourage English language teachers, university professors, and publishers in the fields of TEFL and ESP to provide EFL learners with appropriate sources and settings to increase their familiarity with various metadiscourse markers, especially the category of interactional MDMs that aids them write coherently and establish genuine interaction with audiences.

The flipped classroom model has gained traction in language education; however, its application within English for Specific Purposes (ESP) remains underexplored. The present study investigates the impact of flipped classroom instruction on ESP students’ reading comprehension with a focus on their attitudes toward the model. Adopting a quasi-experimental methodology, the study utilized pretest and posttest assessments alongside a 15-item Likert-scale questionnaire to gather data. The research sample comprised 21 second-semester ESP students from Guilan University majoring in Cellular and Molecular Biology, who engaged in a 10-week intervention. Pre-class preparation included instructional videos and reading materials, while classroom activities centered on group discussions and practical problem-solving tasks. Findings demonstrated a substantial enhancement in posttest scores, validating the approach as effective for improving reading comprehension. The survey results revealed highly positive student attitudes, particularly in terms of engagement, autonomy, and collaborative learning. These findings highlight the potential of the flipped classroom model to address the unique academic requirements of ESP students by blending discipline-specific resources with interactive learning strategies.

This research aims to develop a questionnaire that measures students’ attitudes toward collaborative course design and identifies any barriers that might hinder student participation in course design. The questionnaire was developed in four phases. First, an item pool was created based on experts’ opinions, relevant literature, and the researchers’ experience. Second, the items were classified into two main sections: “attitudes” and “barriers”, with the latter further divided into five subcategories (social and cultural, educational and institutional, individual, practical, and attitudinal). The content validity of the questionnaire was assessed, with all items and subcategories achieving CVR>0.59 and CVI>0.79, thus surpassing the minimum required threshold. Third, the questionnaire was piloted with 330 students. The construct validity of the Collaborative Course Design Questionnaire (CCDQ) was confirmed through exploratory factor analysis (EFA) using Principal Component Analysis (PCA) as the extraction method, along with Varimax rotation, which identified six factors explaining 71.536% of the variance in the data. Finally, Cronbach’s alpha was calculated, yielding reliability indices ranging from 0.971 to 0.627, indicating internal consistency and reliability of the items within each construct. The findings suggest that the Collaborative Course Design Questionnaire is a valid and reliable instrument suitable for use with senior high school students.
