Exploring teaching concerns and characteristics of graduate teaching assistants

The purpose of the study was to explore a conceptual structure of graduate teaching assistant (GTA) teaching concerns. Results indicated that GTAs experience five distinct, inter-related types of concerns: class control, external evaluation, task, impact and role/time/communication. These ‘teaching concerns’ were further analysed by examining their relationship with the value placed on them by the GTAs and the confidence in dealing with the teaching-related issues of concern. The results revealed that GTAs tend to have concerns about self, task or role/time/communication-related issues when the nature of the concerned issues is perceived as being valuable but challenging. On the other hand, GTAs are more likely to have concerns with impact-related issues when the nature of the issues is perceived as both being valuable and manageable. Several GTA characteristics, such as teaching experience, teacher efficacy, participation in professional development and values on teaching practices, were examined as predictors of GTA teaching concerns.     

Graduate teaching assistants: motives,difficulties and professional interactions and their relationship to perceived benefits

ABSTRACT

Graduate students play a major role in teaching in higher education, particularly in undergraduate programs. The purpose of the present study was two-fold: first, to identify graduate students’ motives for working as graduate teaching assistants (GTAs), describe some aspects of their work, and ascertain their perceived benefits; second, to predict GTAs’ benefits as a function of their individual background characteristics, motives, job difficulties, and richness of professional interactions with the course instructor. Data were collected from 189 GTAs who led discussion groups at a large research university in Israel by means of an internet questionnaire. Findings revealed that graduate students accepted the position of GTA mainly for extrinsic reasons, such as salary and convenience. They claimed to have faced few difficulties and that their professional interactions with the course instructors focused more on job responsibilities and less on pedagogical issues. They reported having gained a greater understanding of course content and improved teaching skills due to their experience as GTAs. Richness of contact with the course instructor, motives, difficulties, and faculty match significantly contributed to predicting perceived benefits. The implications of the results are discussed.     

Investigation of chemistry graduate teaching assistants' teacher knowledge and teacher identity

Graduate students play an integral role in undergraduate chemistry education at doctoral granting institutions where they routinely serve as instructors of laboratories and supplementary discussion sessions. Simultaneously, graduate teaching assistants (GTAs) balance major research and academic responsibilities. Although GTAs have substantial instructional facetime with large numbers of undergraduate students, little is known about their conceptions of teaching or their identities as teachers. To investigate the knowledge that GTAs have regarding teaching in this unique context, their teaching identities, and how these developed, we conducted 22 interviews with graduate students from several universities at various levels in their graduate school career using a modified Teacher Beliefs Interview. Interviews were analyzed for two overarching teacher learning constructs: teacher knowledge and teacher identity. We characterized chemistry GTAs' teacher knowledge and identity and determined major influencing factors. We found that chemistry GTAs often identified as a tutor or lab manager, which hindered their self-investment in developing as teachers. The results presented herein contribute to an understanding of GTAs' teacher knowledge, teacher identity, and their teaching context, from which training can be designed to best support GTA development.     

Graduate teaching assistants’ perceptions of teaching competencies required for work in undergraduate science labs

ABSTRACT

Many post-secondary institutions provide training and resources to help GTAs fulfil their teaching roles. However, few programmes focus specifically on the teaching competencies required by GTAs who work with undergraduate students in laboratory settings where learning tends to be more active and inquiry based than in classroom settings. From a review of 8 GTA manuals, we identified 20 competencies and then surveyed faculty and lab coordinators (FIS) and GTAs from a Faculty of Science at a comprehensive Canadian university to identify which of those competencies are required of GTAs who work in undergraduate science labs. GTAs and FIS did not significantly differ in the competencies they view as required for GTAs to work effectively in undergraduate labs. But, when comparing the responses of GTAs and FIS to TA manuals, ‘Clearly and effectively communicates ideas and information with students’ was the only competency for which there was agreement on the level of requirement. We also examined GTAs’ self-efficacy for each of the identified competencies and found no overall relationship between self-efficacy and demographic characteristics, including experience and training. Our results can be used to inform the design of training programmes specifically for GTAs who work in undergraduate science labs, for example, programmes should provide strategies for GTAs to obtain feedback which they can use to enhance their teaching skills. The goal of this study is to improve undergraduate lab instruction in faculties of science and to enhance the teaching experience of GTAs by better preparing them for their role.     

The perceived benefits and problems associated with teaching activities undertaken by doctoral students

Postgraduate students involved in delivering undergraduate teaching while working toward a research degree are known as graduate teaching assistants (GTAs). This study focused upon the problems and benefits arising from this dual role as researchers and teachers, as perceived by GTAs at the University of Cambridge. To this end, GTAs at Cambridge were invited to participate in an online survey (n?=?153). Teaching is seen to offer a wide range of benefits to GTAs, including benefits to the GTAs’ own research, transferable skills development, career development and teaching skills. Time pressures emerged as the principal problem associated with the role. The data are consistent with findings from previous studies, while also providing further detail about the nature of the benefits and problems. In particular, additional insights are offered relating to benefits and problems associated with different teaching activities, and disciplinary differences.     

‘Peacekeepers’ and ‘machine factories’: tracing Graduate Teaching Assistant subjectivity in a neoliberalised university

Guided by a Foucauldian theorisation, this article explores Graduate Teaching Assistant (GTA) experiences of their work and subjectivity in a neoliberalised higher education environment. By drawing on a research project with GTAs from one UK university, the article argues that GTA work is increasingly shaped by neoliberal reforms. The GTAs interviewed are critical of internationalisation, marketisation and client culture, and see these processes as acting on their subjectivity. The GTAs position themselves as mediators between demanding students and overworked academics: they have turned into much-needed ‘peacekeepers’ and ‘machine factories’. The findings also demonstrate that the subjectivity enforced by a dominant market ideology is further negotiated in the GTA experience. The discourses reveal that a lack of institutional control and coordination of graduate teaching provides the means for, and indeed enables, the GTAs to express some, but often limited, discontent with neoliberalism.     

Does Instructor Type Matter? Undergraduate Student Perception of Graduate Teaching Assistants and Professors

Graduate teaching assistants (GTAs) are used extensively as instructors in higher education, yet their status and authority as teachers may be unclear to undergraduates, to administrators, and even to the GTAs themselves. This study explored undergraduate perception of classroom instruction by GTAs and professors to identify factors unique to each type of instructor versus the type of classes they teach. Data collection was via an online survey composed of subscales from two validated instruments, as well as one open-ended question asking students to compare the same class taught by a professor versus a GTA. Quantitative and qualitative results indicated that some student instructional perceptions are specific to instructor type, and not class type. For example, regardless of type of class, professors are perceived as being confident, in control, organized, experienced, knowledgeable, distant, formal, strict, hard, boring, and respected. Conversely, GTAs are perceived as uncertain, hesitant, nervous, relaxed, laid-back, engaging, interactive, relatable, understanding, and able to personalize teaching. Overall, undergraduates seem to perceive professors as having more knowledge and authority over the curriculum, but enjoy the instructional style of GTAs. The results of this study will be used to make recommendations for GTA professional development programs.     

Graduate teaching assistants: how well do their students think they do?

Graduate teaching assistants (GTAs) constitute a valuable and economical teaching force in many higher education undergraduate programmes. However, student satisfaction with their teaching has attracted little attention in the research literature. This study aimed at examining students’ evaluation of teaching of GTAs in discussion groups, as well as exploring the effects of group and GTA variables on these ratings. Data were collected using a questionnaire administered online and completed by 7078 undergraduate students. Participants were enrolled in classes taught by 278 GTAs from four faculties in a major Israeli university. Results indicated that ratings assigned to clarity of instruction were the most salient predictor of students’ overall evaluation. Generally, findings were consistent with those reported in the literature for other categories of instructors. Groups taught by GTAs in exact sciences and engineering were rated higher than those in social sciences and business management. Group size and the percentage of men students were inversely correlated with student ratings, while student attendance rate was positively correlated. Women GTAs and GTAs who taught more than one group tended to receive higher ratings. Overall student attendance rate was the most prominent predictor of student ratings. The implications of the findings are discussed.     

Perceptions and Practices: Biology graduate teaching assistants’ framing of a controversial socioscientific issue

Graduate teaching assistants (GTAs) are gaining increasing responsibility for the instruction of undergraduate science students, yet little is known about their beliefs about science pedagogy or subsequent classroom practices. This study looked at six GTAs who were primary instructors in an introductory biology laboratory course. Teaching assistants taught a lesson about the potential social, health, and environmental impacts of genetically modified crops. Through classroom observations and in‐depth interviews, the researchers examined how instructors chose to frame their lessons and what GTAs perceived as important for students to know about this particular socioscientific issue (SSI). Results showed a disconnect between the relatively mature conceptualizations of effective SSI instruction that emerged during interviews and classroom practice.     

Preparing Biology Graduate Teaching Assistants for Their Roles as Instructors: An Assessment of Institutional Approaches

The inconsistency of professional development (PD) in teaching for graduate teaching assistants (GTAs) is a widespread problem in higher education. Although GTAs serve an important role in retention of undergraduate science majors and in promotion of scientific literacy in nonmajors, they often lack preparation and ongoing support for teaching. Given the recent national focus on instructional quality in introductory courses, our goal was to use an online survey to identify current practices of teaching PD for biology GTAs and compare these results with the last national survey on this topic. In responses from 71 participant institutions, 96% reported some mandatory teaching preparation for biology GTAs; however, 52% of these programs required 10 or fewer hours per year. Respondents wanted to change their programs to include more pedagogical information and teaching observations with feedback to their GTAs. Programmatic self-ratings of satisfaction with GTA PD were positively correlated with the number of topics discussed during PD. Although more schools are requiring GTA PD for teaching compared with the last national survey, the lack of program breadth at many schools warrants a national conversation with regard to recent calls for improving undergraduate instruction.     

Just in time and future-proofing? Policy,challenges and opportunities in the professional development of part-time teachers

Abstract

Part-time teachers form a growing proportion of the global Higher Education (HE) workforce. Their backgrounds can vary from Graduate Teaching Assistants (GTAs) teaching for the first time, to practitioners bringing workplace experience into HE and sessional teachers, all with differing professional development needs. This paper builds on previous research to consider structures and practices promoting sustainable, effective professional development for part-timers, to propose proactive holistic professional development, and raise institutional awareness of the challenges of reaching part-timers. A case study exploring the lived experiences of part-time staff illustrates key features of part-timers’ preparation for their current work and future aspirations.     

Evaluating the impact of the graduate certificate in academic practice (GCAP) programme

Graduate teaching assistants (GTAs) and postgraduates in the UK are taking on greater responsibility for teaching, and therefore it has become increasingly necessary to explore the teacher training that supports them in this endeavour. This paper outlines an impact evaluation carried out on a graduate certificate programme primarily aimed at GTAs and support staff at a research-intensive institution. The concept of impact evaluation is explored. This qualitative research establishes impact on the approaches participants took and their understanding of teaching following on from the programme. Interviews with nine participants, analyses of their critical reflective portfolios, and analyses of their teaching observation commentary are reported on. Findings reveal participants felt they had gained particular skills of teaching, were more reflective, and adopted a more student-centred approach to their teaching. It is recommended that training on specific teaching skills be incorporated into the provision available for GTAs and that disciplinary differences accommodated.     

Exploring pedagogical content knowledge of biology graduate teaching assistants through their participation in lesson study

Graduate teaching assistants (GTAs) are responsible for teaching the majority of biology undergraduate laboratory sections, although many feel underprepared to do so. This study explored the impact of biology GTA participation in a professional development model known as lesson study. Using a case study methodology with multiple qualitative data sources, this study found that lesson study was beneficial for this group of GTAs in that it modified critical aspects of their beliefs about biology instruction. Each participant felt that lesson study helped revise their teaching and changes were seen in some aspects of the participants’ Pedagogical Content Knowledge (PCK). Despite this, there was an observed disconnect between participants’ vocalized intent and classroom practice. This disconnect could be attributed to the difficulty of implementing new strategies, the short duration of the lesson study, and the instructional inexperience of the participants in the study.     

Growing a garden without water: Graduate teaching assistants in introductory science laboratories at a doctoral/research university

Graduate teaching assistants (GTAs) in the sciences are a common feature of U.S. universities that have a prominent mission of research. During the past 2 decades, increased attention has been paid to the professional development of GTAs as instructors. As a result, universities have created training programs to assist GTAs in selecting instructional methods, curricular formats, and assessments when they serve as laboratory, lecture, or discussion group instructors. Unfortunately, few studies explore the educational and instructional environment of GTAs in these reformed settings. This study was conducted to address this specific need. As a constructivist inquiry, qualitative methods were used to collect and analyze the data to elucidate the educational and instructional environment of science GTAs at a doctoral/research university in which various training programs existed. We found that GTAs worked autonomously, that traditional practices and curricula existed in laboratories, and that instructors frequently held limited views of undergraduates' abilities and motivation. Findings in this initial study about GTAs suggest that developers of GTA training programs draw on the literature regarding science teacher education, and that reward systems be instituted that recognize faculty and staff for their participation in GTA training programs. © 2004 Wiley Periodicals, Inc.

The genesis of mentors’ professional and personal knowledge about teaching: perspectives from the Republic of Ireland

This study investigates the sources of mentors’ knowledge about teaching. A mixed-method research design combining quantitative and qualitative data collection methods was used to examine this area. The findings of the study suggest that: mentors’ knowledge about teaching is practice orientated and emerges from their professional experiences, their teaching skills, their pre-service teacher education and, to a considerable extent, from their own personal experiences. The authors argue that mentors require support to reflect on their early socialisation experiences and their attachment to practice-based experience as a source of professional knowledge, in this way they can better understand and carry out their role as mentors.     

NGTA and IGTA Training and Experience: Comparisons Between Self-Ratings and Undergraduate Student Evaluations

Undergraduate student ratings and corresponding graduate teaching assistant (GTA) self-ratings of nine teaching effectiveness factors were evaluated to determine the extent to which math and science GTAs who speak English as their native language (NGTA) differ from their international counterparts (IGTA). Overall, GTA self-ratings were consistently higher than corresponding student ratings. Differences in ratings between the two groups of GTAs were dependent upon specific teaching effectiveness factors and the source of the rating. GTA self-ratings were generally higher for IGTAs while student ratings were consistently higher for NGTAs.David M.

Improving pre‐service teacher learning through peer teaching: process,people and product1

This research investigates the perceptions of first‐year Bachelor of Teaching students (primary and secondary) and Diploma of Education students (secondary) about their peer teaching experience in a postgraduate subject called Curriculum and Assessment. Peer teaching is a learner‐centred approach to teaching and learning that is intended to provide significant benefits for learners' knowledge, skills and metacognition. However, concerns have been raised over the quality of the learning and teaching and the risks associated with such a pedagogy. In the present study, student responses to questionnaires and semi‐structured interviews were analysed, using a mixed methods approach, with respect to three broad and somewhat interconnected categories: process, people and product. These responses suggested a wide range of reactions to peer teaching, but overall students feel they benefited from the experience. The findings of this study should be of interest to lecturers and students in pre‐service teacher education courses, especially. Knowledge about peer teaching, learning and assessment would be especially valuable for both education lecturers and beginning teachers seeking to design and manage learner‐centred pedagogy in their own primary, secondary and tertiary classrooms. However, the results of this research would have far‐reaching appeal for all teaching and learning contexts.     

Discipline orientations of pre‐service teachers before and after student teaching

This study examined the classroom discipline orientations of pre‐service elementary teachers both before and after the student teaching experience. Prior to beginning and immediately after completing their full‐time student teaching experience, pre‐service teachers (N = 220) from three southeastern universities in the USA completed a discipline belief instrument which identified their preferred model of classroom discipline. The results showed that the student teaching experience significantly increased beginning teachers’ preferences toward a more assertive discipline model (Rules and Consequences) and decreased their preferences toward the humanistic discipline model (Relationship–Listening). These results demonstrate that the student teaching experience may be creating a dissonance in prior knowledge and beliefs, and experiences of pre‐service teachers in classrooms. The results of the study suggest that teacher education programs can help pre‐service teachers transition more smoothly into classroom teaching by providing a school–university partnership as well as more lessons and advice on handling specific classroom management situations.
