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

Alternation of generations and experimental design: a guided-inquiry lab exploring the nature of the her1 developmental mutant of Ceratopteris richardii (C-Fern) 
下载免费PDF全文
下载免费PDF全文 Inquiry-based labs have been shown to greatly increase student participation and learning within the biological sciences. One challenge is to develop effective lab exercises within the constraints of large introductory labs. We have designed a lab for first-year biology majors to address two primary goals: to provide effective learning of the unique aspects of the plant life cycle and to gain a practical knowledge of experimental design. An additional goal was to engage students regardless of their biology background. In our experience, plant biology, and the plant life cycle in particular, present a pedagogical challenge because of negative student attitudes and lack of experience with this topic. This lab uses the fern Ceratopteris richardii (C-Fern), a model system for teaching and research that is particularly useful for illustrating alternation of generations. This lab does not simply present the stages of the life cycle; it also uses knowledge of alternation of generations as a starting point for characterizing the her1 mutation that affects gametophyte sexual development. Students develop hypotheses, arrive at an appropriate experimental design, and carry out a guided inquiry on the mechanism underlying the her1 mutation. Quantitative assessment of student learning and attitudes demonstrate that this lab achieves the desired goals. 相似文献

INTRODUCTION Total quality management (TQM), as a manag- ing concept and method, achieved much in every aspect of life, has been praised highly by various managers and supervisors, and has been commonly applied in libraries in the world. But, as a newly mushrooming digital library, there are still different opinions and ideas on its operation model and man- aging method (Li, 2005). Based upon thorough re- search on the TQM system, the problem of applying TQM in digital library is discu… 相似文献

The expression “big data” is ubiquitous in the business world today, but few undergraduate business students have the opportunity to gain practical experience with how new business analytics tools can be used in decision making. This article describes a set of hands‐on labs that prepare students to incorporate streaming data analysis into group research projects. Splunk is used to help students analyze and visualize streaming social media data. An evaluation of student projects and student survey results show that this practical approach of training students to manipulate and visualize big data was largely successful in achieving instructional goals. 相似文献

Early research experiences must be made available to all undergraduate students, including those at 2-yr institutions who account for nearly half of America''s college students. We report on barriers unique to 2-yr institutions that preclude the success of an early course-based undergraduate research experience (CURE). Using a randomized study design, we evaluated a CURE in equivalent introductory biology courses at a 4-yr institution and a 2-yr institution within the same geographic region. We found that these student populations developed dramatically different impressions of the experience. Students at the 4-yr institution enjoyed the CURE significantly more than the traditional labs. However, students at the 2-yr institution enjoyed the traditional labs significantly more, even though the CURE successfully produced targeted learning gains. On the basis of course evaluations, we enhanced instructor, student, and support staff training and reevaluated this CURE at a different campus of the same 2-yr institution. This time, the students reported that they enjoyed the research experience significantly more than the traditional labs. We conclude that early research experiences can succeed at 2-yr institutions, provided that a comprehensive implementation strategy targeting instructor, student, and support staff training is in place. 相似文献

The purpose of this paper is twofold: to describe robust rationales for integrating inquiry-based learning into undergraduate science education, and to propose that digital libraries are potentially powerful technological tools that can support inquiry-based learning goals in undergraduate science courses. Overviews of constructivism and situated cognition are provided with regard to how these two theoretical perspectives have influenced current science education reform movements, especially those that involve inquiry-based learning. The role that digital libraries can play in inquiry-based learning environments is discussed. Finally, the importance of alignment among critical pedagogical dimensions of an inquiry-based pedagogical framework is stressed in the paper, and an example of how this can be done is presented using earth science education as a context. 相似文献

This study attempted to investigate students’ perceptions toward the use of the digital library in weekly web‐based distance learning assignments portion of a hybrid instructional programme. Attention was given to three variables—age, gender, and prior experience with the Internet. A Likert‐type instrument consisting of 10 items was designed to collect information about students’ perceptions toward the use of digital library. The subjects of this study were 154 students enrolled in an undergraduate hybrid programme in management at a medium‐sized university in the Midwest, USA. Collected data were analysed using ANOVA. The overall results suggest that students had positive perceptions toward the use of the digital library. Age was found to be an insignificant factor. However, gender and prior experience with the Internet were found to be significant factors. Males had significantly higher positive perceptions toward using the digital library. Students who had more prior experience with the Internet had significantly higher positive perceptions toward using the digital library. Implications for practice are discussed and recommendations are made for future research. 相似文献

In undergraduate engineering labs, lab reports are routinely copied. By ignoring this form of plagiarism, teaching assistants and lab technicians neglect their role responsibility. By designing courses that facilitate it, however inadvertently, professors neglect their causal responsibility. Using the case of one university, we show via interviews and observation that such routine copying and faculty negligence are rampant. We suggest the latter be explicitly recognized as a cause of student dishonesty, and argue that it must be rectified before faculty earn the right to reform students. We also suggest that these findings are representative of, and therefore generalizable to, many universities’ undergraduate engineering and science labs. 相似文献

Providing undergraduates with mentored research experiences is a critical component of contemporary undergraduate science education. Although the benefits of undergraduate research experiences are apparent, the methods for mentoring young scientists as they first begin navigating the research lab environment are reinvented in labs all over the world. Students come to research labs with varied skills, motivations, needs, and dispositions, placing each student and mentor in a unique relationship. How can we help students become aware of their own intellectual progress? How can we encourage our students to take initial steps toward independent investigation? When do we need to let setbacks happen? We have developed a simple mechanism to address these common problems. Each week, students in our labs answer a series of five questions by e-mail that improve lab communication and help students develop into mature scientists without taxing an instructor's already busy schedule. Our observations, experiences, and student feedback indicate that this approach is a useful mechanism to help faculty who mentor young scientists in the research lab. 相似文献

Most young people go to their friends for information on sexuality-related topics, thus it is important to understand the context of these communications so that we may gather insight into sexual values and the underlying emotions and styles of communication. We conducted qualitative weekly surveys regarding discussion of sexual health topics among peers with students enrolled in an undergraduate human sexuality course. A four-stage inductive analysis process was utilized to examine a total number of 824 survey submissions from 102 college students who agreed to participate. Seven relevant common themes emerged: safer sex, sexually transmitted infections, pregnancy, feelings about sex, sexual acts, peer support, and peer communication norms. Some perspectives varied between males and females. Life events create opportunities for peers to discuss sexual health with each other. The connection between life events and peer sexual health communication has numerous implications for both research and education. 相似文献
