Nearly 50% of graduate students report experiencing emotional or psychological distress during their enrollment in graduate school. Levels of distress are particularly high for transgender and non-binary graduate students who experience daily discrimination and marginalization. Universities and colleges have yet to address and accommodate the needs and experiences of transgender and non-binary graduate students. Given the multitude of challenges these students may face, educational settings should not present additional barriers to educational success and well-being. In an effort to improve graduate education for transgender and non-binary students, we add to the existing scholarship on affirming work with transgender undergraduate students by addressing the unique concerns of graduate students. We utilize a social-ecological model to identify sources of discrimination in post-secondary education and to provide transgender- and non-binary-affirming recommendations at structural, interpersonal, and individual levels. For practitioners who wish to do personal work, we provide guidance for multicultural identity exploration. A table of recommendations and discussion of ways to implement our recommendations are provided.

Because critical analysis of published information is an essential component of scientific life, it is important that students be trained in its practice. Undergraduate students who are more accustomed to reading textbooks and taking lecture notes find it difficult to appreciate primary publications. To help such students, we have developed a checklist that helps them analyze different components of a research article in basic biomedical sciences. Students used the checklist to analyze critically a published article. The students were assigned an article and asked to write a paper (maximum 2 pages of single-spaced type) assessing it. This assignment has been found useful to both undergraduate and graduate students in pharmacology and physiology. Student responses to a questionnaire were highly favorable; students thought the exercise provided them with some of the essential skills for life-long learning.

One moment from the much-discussed 2017 curriculum reform in the Music Department at Harvard University has stuck with me and transformed the way I approach teaching music in higher education. In one of the meetings leading up to the revision, graduate students in the department led an activity in which attendees—who included undergraduate students, graduate students, and faculty alike—got into small groups and discussed the relative merits of three hypothetical models for the new undergraduate curriculum. Each of the models involved decentering to some extent the existing curriculum's emphasis on the history of Western European music and dominant music theoretical approaches to it. After a short while, we all gathered back together and one person from each group shared a bit about what had transpired. From the circle of desks nearest the door, an undergraduate student rose to speak and expressed enthusiasm for a broadening of curricular coverages. But, they said, their group also had some reservations about jettisoning the overall focus on Western European concert music altogether. “We still need to learn about our history,” they said, while a faculty member nodded behind them.

The present study is conducted to measure religiosity and stress of graduate students belonging to gender living in Marathwada. The investigators employed one independent variables, gender can influence the religiosity and stress of students. The study was carried out on the sample of graduate students. To measure the religiosity and stress the researcher used the standardized scale of Bhusan and Bisht Battery of stress. The sample consisted of 100 students, out of which, 50 were males and 50 females. The findings of the study revealed that there is significant difference in the religiosity and stress of undergraduate students. Correlation between religiosity and stress is not significant found.

This paper reports on a pilot project that involved the incorporation of Community Service-Learning (CSL) into a large Introductory Sociology class by drawing on the critical reflections of the six graduate student instructors and the primary instructor who taught the course. Graduate student instructors individually facilitated weekly seminars for about 30 undergraduate students, half of which participated in CSL, completing 20 hours of volunteer work with a local non-profit community organization. We discuss the benefits of incorporating CSL into a large Introductory Sociology class and speculate on the value of our particular course format for the professional development of graduate student instructors. A main finding was the critical importance to graduate students of formal and informal training and collaboration prior to and during the delivery of the course. Graduate students found useful exposure to CSL as pedagogical theory and practice, and appreciated the hands-on teaching experience. Challenges with this course structure include the difficulty of seamlessly incorporating CSL student experiences into the class, dealing with the “CSL”/ “non CSL” student division, and the nature of some of the CSL placements. We conclude by discussing possible methods for dealing with these challenges.

The choice of media as a career has conventionally not been a top priority amongst undergraduate students in India. Despite the surging need for responsible media professionals in a developing country like India, this career is not widely accepted or chosen. This research aimed at determining specific motivations among the first-year undergraduate students choosing a career in media. The same were determined through expert interactions followed by an online survey to include over 400 students pursuing an undergraduate programme at various colleges across India. The analysis showed that undergraduate media students are passionate with a deep interest in the concerned field and have an enhanced need to be different from others. They are creative, highly communicative, would like to pursue their interest and passion as well as distinguish themselves from conventional career seekers. Choice of media as a career at the undergraduate level is preferred more by female students compared to their male counterparts. Most interestingly and importantly, media as a career is mostly against the wishes of parents; the influence of parents being negative. This study contributes to a deep understanding of motivational factors and their criticalities in influencing the young generation in India. The factors can aid the educational policymakers, academicians, industry experts, and researchers to develop strategies to encourage students to choose a career in media. This research also serves as a starting point to generate discussions to change the belief and attitudes of parents towards media as a career option for their wards.

Oral health status is directly proportional to a person's oral health behaviour. Oral health of a person can be determined by their regular oral habits like brushing, flossing, smoking and regular dental check-up. Maintenance of poor oral health can lead to severe dental problems. The aim of the study is to create awareness about oral health and behaviour among the dental and engineering undergraduate students. The self-administered questionnaire prepared about oral health behaviour, distributed to 100 dental and engineering graduate students through online google link and data is collected and analysed. From the collected data, 87.18% of dental students brush daily, and 84.62% of engineering students use dental floss to clean the gap between the teeth. This survey helps to bring knowledge on the awareness of oral health behaviour among the dental and engineering students. From this survey, we have concluded that dental students have good oral hygiene when compared to engineering students.

The emergence of the Internet has made many institutions involved in the delivery of distance education programs re-evaluate the course delivery framework. A variety of models and techniques co-exist in an often uneasy alliance at many such institutions. These range from the traditional distance learning model, which remains paper-based, to the purely online model. Recently, hybrid models have emerged which apparently attempt to forge elements taken from several models into a unified whole. Many of these hybrid models seek to eliminate paper-based materials from the tuition process. While many arguments are put forward about the efficacy of purely electronic delivery mechanisms, cost containment is often the driving motivation. This study explores student perceptions of the various delivery mechanisms for distance learning materials. In particular, it seeks to determine what value students place on paper-based delivery mechanisms. The study surveys a group of undergraduate students and a group of graduate students enrolled in the Faculty of Business at a large regional Australian university.

AbstractDespite being responsible for a large percentage of undergraduate instruction, graduate students often receive little preparation for their first solo teaching assignments (J. D. Nyquist et al.,Change31 (3): 18, 1999). Furthermore, the existing literature on pedagogy fails to address the unique challenges faced by graduate students who are asked to serve as course instructors rather than teaching assistants. This article presents seven pieces of advice intended to better prepare the predoctoral graduate student to assume the role of the professor before assuming the title. By understanding the attitudes of undergraduate students toward graduate instructors, preparing in advance to handle the mistakes that novice teachers often make, and recognizing the correlation between outward confidence and student perceptions of instructor quality, graduate students can derive the most benefit from a stressful and time-consuming assignment. Most important, graduate instructors can learn to effectively manage the time spent on teaching duties to ensure that other responsibilities such as coursework, qualifying exams, and dissertation research do not suffer.
