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. 相似文献

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. 相似文献

ABSTRACTMany 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. 相似文献

ABSTRACTGraduate 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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

Many innovative teaching approaches lack classroom impact because teachers consider the proposals impractical. Making a teaching approach practical requires instrumentality (procedures), congruence (local fit), and affordable cost (limited time and resources).This paper concerns a study on the development and effects of a participatory design based teacher training trajectory aimed at making guided discovery learning (GDL) practical for student biology teachers. First, we identified practical heuristics for designing GDL lessons by analyzing design protocols made by biology teachers who are experts in GDL. Next we inventoried student responses to their regular lessons and to GDL based lessons. Based on this we prepared a teacher training program for eleven student biology teachers in which they applied the heuristics and stepwise extended their teaching repertoire in the direction of GDL. The participants’ design processes and resulting lesson plans were scored on both use of design heuristics and GDL characteristics. The participants were interviewed about their motivational beliefs before and after the program. Results showed that student teachers are able to design GDL lessons and used the heuristics to design GDL lessons. Their motivation for implementing GDL in their classroom had increased substantially. The paper concludes with a critical reflection on our method of participatory design and its applicability. 相似文献

In order to understand how prospective teachers develop knowledge for teaching, researchers must identify the types of knowledge that are integral to effective science teaching. This case study investigated how 4 prospective secondary biology teachers’ science teaching orientations, knowledge of science learners, and knowledge of instructional sequence, developed during a post-baccalaureate teacher education program. Data sources included a lesson planning task and two interview-observation cycles during the participants’ year-long internship. Over the course of a year, the participants’ science teaching orientations were based primarily on their K-16 learning experiences, and were robust and highly resistant to change. The prospective teachers became more aware of student learning difficulties, and therefore, developed more elaborated knowledge of the requirements of learning. They consistently sequenced instruction in ways that gave priority to transmitting information to students. Prospective teachers’ development of knowledge of student understanding of science and instructional sequence were congruent with their science teaching orientations. Implications are given for teacher education and future research. 相似文献

Though it is well known that pre-service teachers’ field experiences are recognized as key to enhancing teaching practice, Taiwanese pre-service teachers who take ‘Teaching Methods and Materials’ in elementary school’s seven areas often complain that they lack field experience. They do not have the opportunity to experience teaching demonstrations among real elementary school students. This case study discusses 35 pre-service English teachers’ professional learning and the field experience they acquired from expert teachers in the Teaching Methods and Materials of English in the Elementary School course in Taiwan. Data in this study include: (1) observation notes, (2) lesson plans, worksheets, and teaching materials, (3) videos on teaching demonstrations, (4) conversation notes on lesson planning, (5) the class syllabus, (6) semi-structured interviews with expert teachers, and (7) participants’ reflections on their mentoring experience. Participants held positive attitudes toward the mentoring experience and their expert teachers. Because it helped them combine their knowledge of the classroom context, lesson plan content, instructional pedagogy, and their students, these 35 participants regarded teaching practice as more beneficial than observing expert teachers’ instructions and having conversation with expert teachers after teaching practice. In addition to mentored field experience, online discussions and seminars on topics are suggested for inclusion in mentoring activities. 相似文献

For successful reading experiences in native and/or foreign/second language, individuals need to benefit from not only cognitive strategies but also metacognitive strategies. Although research found reading comprehension and performance increase following metacognitive trainings, such findings may not transfer into mainstream classrooms as easily for several reasons. This study, therefore, aimed to disseminate the phenomenon of teaching metacognition with an emphasis on teacher’s instrumental role during classroom learning. More specifically, it investigated language instructors’ metacognition and their self-reported competencies for teaching metacognition. It also examined whether and how self-reported competencies changed following a professional development (PD) module of teaching for metacognition. Utilising Metacognitive Awareness Inventory (MAI) and think aloud protocols for instructional planning, this study found most participants were either highly metacognitive or metacognitive individuals. It was also found that most participants were initially not knowledgeable about and/or competent in teaching metacognition. Following PD, highly metacognitive teachers developed authentic lesson plans manifesting metacognition instruction while metacognitive teachers adopted similar instructional designs presented during the PD. Besides, half of the participants appreciated teaching metacognitively following the PD. Finally, under the light of these findings, future research and policy adjustments were proposed. 相似文献

This paper reports findings from a project that explored the use of a modified form of ‘lesson study’ in a one-year programme of secondary school initial teacher education (ITE). Twelve mentors and student-teachers worked in pairs to design and teach two ‘research lessons’ in the course of two eight-week teaching practice placements as part of a university–school partnership for the preparation of new teachers. Participating student-teachers reported that engagement in this form of lesson study with a mentor was an effective way to help them grow individual teaching skills, knowledge and confidence in teaching placements. In addition, in most cases, it enabled active and creative participation in a community of teacher learners. However, engagement in lesson study not only supported student-teachers to meet ‘qualifying to teach’ standards, but also offered opportunities for holistic study of teaching and learning, leading to growth in what we characterise as ‘pedagogic literacy’. 相似文献

This study investigated how a collaborative mentoring program influenced beginning science teachers' inquiry-based teaching and their reflection on practice. The one-year program consisted of five one-on-one mentoring meetings, weekly science education seminars, weekly mentoring group discussions, and self-evaluation activities. The participants were three beginning science teachers and three mentors at the middle school level (7–9th grades) in an urban area of South Korea. For each beginning teacher, five lessons were evaluated in terms of lesson design/implementation, procedural knowledge, and classroom culture by using the Reformed Teaching Observation Protocol. Five aspects of the beginning teachers' reflections were identified. This study showed that a collaborative mentoring program focusing on inquiry-based science teaching encouraged the beginning teachers to reflect on their own perceptions and teaching practice in terms of inquiry-based science teaching, which led to changes in their teaching practice. This study also highlighted the importance of collaborative interactions between the mentors and the beginning teachers during the mentoring process. 相似文献

Knowledge structure is an important aspect for defining students’ competency in biology learning, but how knowledge structure is influenced by the teaching process in naturalistic biology classroom settings has scarcely been empirically investigated. In this study, 49 biology lessons in the teaching unit blood and circulatory system in 9th grade German classrooms were videotaped and analyzed. Before the lesson, a questionnaire was administered to the students to solicit their responses about learning motivation. After the lesson, students’ learning outcomes on knowledge structure were examined with the concept mapping method. The video coding used in this study focused on the knowledge linking levels during the biology lesson. Out of the 49 classes, those with the highest and those with the lowest linking levels were selected based on the coding results. In high-linking classes, interrelated facts were introduced more often in the lessons, whereas in the lessons of the low-linking classes, isolated pieces of knowledge were predominant. The results from the concept mapping task showed that the students in the high-linking classes constructed more correct relations among the concepts compared to the students in the low-linking classes. The results remained stable even after controlling for learning motivation. These findings confirm the importance of teaching interrelated facts and concepts instead of isolated facts for fostering students’ knowledge structure. As a result, based on the Bavarian biology curriculum, we develop materials and programs to enable students, student teachers, and teachers to focus on interrelated facts and basic concepts instead of isolated facts in biology lessons. 相似文献

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. 相似文献
