An Investigation into Native and Non Native English Speaking Instructors' Assessment of University ESL Student's Oral Presentation

This thesis aims to conduct a mix-methods investigation into native English-speaking teachers (NESTs) and non-native English-speaking teachers (NNESTs) assessment of university level English as a second language (ESL) student’s oral presentation. To collect data for this study, all faculty members and instructors currently teaching in at the departments of English and Communication Studies at Minnesota State University, Mankato (MNSU) were invited to participate in an online survey using Qualtrics Survey Software (Qualtrics). After receiving email invitations, altogether 31 people provided their consent to participate. Among the 31 teacher-participants, there were 19 NESTs and 12 NNESTs. The participants then took part in the data collection process by completing the online survey where they firstly watched and assessed a video-recorded oral presentation of an ESL student by scoring her performance using an analytic rating scale and then provided feedback on the student’s strengths and areas of weakness. Secondly, each participant rated a question-item section on the survey about which oral presentation assessment criteria they thought was most or least important to them as raters. Finally, the participants answered five biographic questions to provide required personal information. The data was analyzed using Qualtrics and SPSS 23 Software. To begin the data analysis, the participants were divided into two groups, i.e. group 1 NEST and group 2 NNEST on the basis of the participant’s biographic data provided on Qualtrics. Afterward, SPSS was used to calculate descriptive statistics such as the mean (M) and standard deviation (SD) of the data, and to conduct a t-test to compare the data from the two groups and identify any significant difference between them. Next, to determine the inter-rater reliability, the Intraclass Correlation Coefficient on SPSS was used to estimate the Cronbach Alpha for: 1), all the participants; 2), the NEST participants; and 3) the NNEST participants. As it is a mixed-methods research study, the
