Research suggests that undergraduate students learn more from lab experiences that involve longer-term projects. We have developed a one-semester laboratory sequence aimed at sophomore-level undergraduates. In designing this curriculum, we focused on several educational objectives: 1) giving students a feel for the scientific research process, 2) introducing them to commonly used lab techniques, and 3) building skills in both data analysis and scientific writing. Over the course of the semester, students carry out two project-based lab experiences and write two substantial lab reports modeled on primary literature. Student assessment data indicate that this lab curriculum achieved these objectives. This article describes the first of these projects, which uses the biflagellate alga Chlamydomonas reinhardtii to introduce students to the study of flagellar motility, protein synthesis, microtubule polymerization, organelle assembly, and protein isolation and characterization. 相似文献

This study reports on science student perceptions of their skills (scientific knowledge, oral communication, scientific writing, quantitative skills, teamwork and ethical thinking) as they approach graduation. The focus is on which teaching activities and assessment tasks over the whole programme of study students thought utilised each of the six nominated skills. In this quantitative study involving two Australian research-intensive universities, the teaching activities identified by students as developing the broadest number of skills were laboratory classes and tutorials. Lectures were only effective for developing scientific knowledge and, to a limited extent, ethical thinking. Assessment tasks that students perceived to utilise the broadest range of skills were assignments and oral presentations. The findings of this study document the students’ perspective about their gains in skill sets, and the teaching activities and assessment tasks that require them to use and thus develop these skills. The findings provide an opportunity to evaluate the constructive alignment of skills development, teaching activities and assessment tasks from a student’s perspective. Further research is required to actually measure the skills that students gain over their whole programme of study. 相似文献

We tested the hypothesis that engagement in a few, brief writing assignments in a nonmajors science course can improve student ability to convey critical thought about science. A sample of three papers written by students (n = 30) was coded for presence and accuracy of elements related to scientific writing. Scores for different aspects of scientific writing were significantly correlated, suggesting that students recognized relationships between components of scientific thought. We found that students' ability to write about science topics and state conclusions based on data improved over the course of three writing assignments, while the abilities to state a hypothesis and draw clear connections between human activities and environmental impacts did not improve. Three writing assignments generated significant change in student ability to write scientifically, although our results suggest that three is an insufficient number to generate complete development of scientific writing skills. 相似文献

One of the best opportunities that undergraduates have to learn to write like a scientist is to write a thesis after participating in faculty-mentored undergraduate research. But developing writing skills doesn't happen automatically, and there are significant challenges associated with offering writing courses and with individualized mentoring. We present a hybrid model in which students have the structural support of a course plus the personalized benefits of working one-on-one with faculty. To optimize these one-on-one interactions, the course uses BioTAP, the Biology Thesis Assessment Protocol, to structure engagement in scientific peer review. By assessing theses written by students who took this course and comparable students who did not, we found that our approach not only improved student writing but also helped faculty members across the department--not only those teaching the course--to work more effectively and efficiently with student writers. Students who enrolled in this course were more likely to earn highest honors than students who only worked one-on-one with faculty. Further, students in the course scored significantly better on all higher-order writing and critical-thinking skills assessed. 相似文献

Learning science through writing: associations with prior conceptions of writing and perceptions of a writing program 总被引：1，自引：0，他引：1
Students in a large undergraduate biology course were expected to write a scientific report as a key part of their course design. This study investigates the quality of learning arising from the writing experience and how it relates to the quality of students’ preconceptions of learning through writing and their perceptions of their writing program that led to their report. Closed‐ended questionnaires investigating student conceptions and perceptions of writing, and approaches to writing, were completed by 121 students. Significant associations were found amongst qualitatively different prior and post conceptions of writing, approaches to writing and achievement. The results of the analyses suggest that the effective support of student experiences of writing reports requires teachers to be aware of the type of conceptions that students bring to their course and the perceptions they hold about the purpose of the writing program in which they are engaged. 相似文献

This article explores the introduction of science writing into the undergraduate classroom. By asking students to write about science for popular audiences, teachers can illuminate the social and cultural aspects of science that are often lost in the complex prose of scientists writing to their peers. Not much has been written about the place of science writing in technical writing classrooms, though some articles focus on the process of training students to be science staff writers for a newspaper or magazine. But teaching science writing goes beyond professionalization. It has to do with a poetics of science that heightens and enhances our appreciation of the world around us. 相似文献

Learning how to effectively write a literature review is a critical tool for success for an academic, and perhaps even professional career. Being able to summarize and synthesize prior research pertaining to a certain topic not only demonstrates having a good grasp on available information for a topic, but it also assists in the learning process. Although literature reviews are important for one’s academic career, they are often misunderstood and underdeveloped. This article is intended to provide both undergraduate and graduate students in the criminal justice field specifically, and social sciences more generally, skills and perspectives on how to develop and/or strengthen their skills in writing a literature review. Included in this discussion are foci on the structure, process, and art of writing a literature review. 相似文献

This study investigates the approaches adopted by students to a university writing programme designed to help them learn first‐year undergraduate science. The research design includes phenomenographic analyses of 19 interviews and 50 open‐ended questionnaires, as well as quantitative analyses of the qualitative data. The main results of the study are the close association between the quality of the students’ approaches to writing, including when they use technology, to the way they think about writing as a way of learning, and to the level of achievement they reach. The results suggest that writing programmes designed to help students learn science would be improved if their tasks embed issues such as what learning is possible through writing, how new technologies can be used to support meaningful writing and who should be offering models of how to approach university writing most meaningfully. 相似文献

The international project described in this paper has been inspired by the Trans-Atlantic and Pacific Projects (TAPP). By 2013, the TAPP network had connected classes in writing, usability testing and/or translation at three universities in the US and several partner universities in Europe, Africa and China. The pedagogical import of these forms of collaboration has been emphasised in studies that analysed the dynamics of cross-cultural virtual teams. The goal of our study was to have first-year undergraduate students in the US learn what is at stake when they write a text for an ‘alien’ audience. At the Italian end, we wanted students to enhance English as a lingua franca (ELF) reading and writing skills as well as to raise their cross-cultural language awareness. Another goal for both groups of students was to communicate via email, Facebook and other online environments using ELF. 相似文献

In this investigation, three classes of ninth-grade general science students participated in a collaborative report-writing intervention. The purpose of this portion of the study was to evaluate students' collaboratively written laboratory reports for evidence of the use of scientific reasoning skills and to document qualitative changes in reasoning skill use over time. The participants in the study were 6 ninth-grade students, representing three collaborative writing pairs. During the intervention, students wrote 10 laboratory reports over a 4.5-month period. The author and classroom teacher designed report guideline prompts to scaffold students in the use of relevant scientific reasoning skills. The results indicated that students used reasoning skills to assess their current models of scientific understanding, make observations, interpret the meaning of results, and generate new models based on their data and relevant information. Participants showed the most improvement in writing that reflected the reasoning skills of (a) selecting and processing textbook passages, (b) drawing conclusions and formulating models, and (c) comparing/contrasting. Over time, participants improved their ability to compose explanations that represented a synthesis of prior knowledge, activity observations, and other sources of information. Collaborative writing encouraged students to construct their own understandings of science concepts by creating an environment in which thinking, reasoning, and discussion were valued. 相似文献

Contemporary undergraduates in the biological sciences have unprecedented access to scientific information. Although many of these students may be savvy technologists, studies from the field of library and information science consistently show that undergraduates often struggle to locate, evaluate, and use high-quality, reputable sources of information. This study demonstrates the efficacy and pedagogical value of a collaborative teaching approach designed to enhance information literacy competencies among undergraduate biology majors who must write a formal scientific research paper. We rely on the triangulation of assessment data to determine the effectiveness of a substantial research paper project completed by students enrolled in an upper-level biology course. After enhancing library-based instruction, adding an annotated bibliography requirement, and using multiple assessment techniques, we show fundamental improvements in students' library research abilities. Ultimately, these improvements make it possible for students to more independently and effectively complete this challenging science-based writing assignment. We document critical information literacy advances in several key areas: student source-type use, annotated bibliography enhancement, plagiarism reduction, as well as student and faculty/librarian satisfaction. 相似文献

Our objective was to investigate the impact of the Science Writing Heuristic (SWH) on undergraduates’ ability to express logical conclusions and include appropriate evidence in formal writing assignments. Students in three laboratory sections were randomly allocated to the SWH treatment (n?=?51 students) with another three sections serving as a control (n?=?47 students). All sections received an identical formal writing assignment to report results of laboratory activities. Four blinded raters used a 6-point rating scheme to evaluate the quality of students’ writing performance. Raters’ independent scoring agreement was evaluated using Cronbach's α. Paper scores were compared using a t-test, then papers were combined into low-scoring (3.5 of 6 points) or high-scoring (>3.5 of 6 points) sets and SWH and control cohorts were compared using Pearson's chi-square test. Papers from the SWH cohort were significantly (P?=?0.02) more likely to receive a high score than those from the control cohort. Overall scores of SWH cohort papers tended to be higher (P?=?0.07) than those from the control cohort. Gains in student conceptual understanding elicited by the SWH approach improved student ability to express logical conclusions about their data and include appropriate evidence to support those conclusions in formal research reports. Extending the writing tasks of the SWH to formal writing assignments can improve the ability of undergraduates to argue effectively for their research findings. 相似文献

We developed a rubric for measuring students' ability to reason and write scientifically. The Rubric for Science Writing (Rubric) was tested in a variety of undergraduate biology laboratory courses (total n = 142 laboratory reports) using science graduate students (teaching assistants) as raters. Generalisability analysis indicates that the Rubric provides a reliable measure of students' abilities (g = 0.85) in these conditions. Comparison of student performance in various biology classes indicated that some scientific skills are more challenging for students to develop than others and identified a number of previously unappreciated gaps in the curriculum. Our findings suggest that use of the Rubric provides three major benefits in higher education: (1) to increase substance and consistency of grading within a course, particularly those staffed by multiple instructors or graduate teaching assistants; (2) to assess student achievement of scientific reasoning and writing skills; and (3) when used in multiple courses, to highlight gaps in alignment among course assignments and provide a common metric for assessing to what extent the curriculum is achieving programmatic goals. Lastly, biology graduate students reported that use of the Rubric facilitated their teaching and recommended that training on the Rubric be provided to all teaching assistants. 相似文献

Scientific writing is related to the practice of communicating scientific knowledge. This study treats scientific writing as a social practice, taking as its premise the notion that participating in related activities such as reading, peer evaluation, and discussion would positively affect the competence of students’ scientific writing, by developing their epistemic cognition regarding scientific knowledge communication and legitimation. An empirical study was conducted with twenty-two Chinese undergraduate students to test this premise. These students were majoring in chemistry and undertook a researcher-designed intervention course (Advanced Organic Chemistry Experiment), which embodied the integrated strategy of reading, peer evaluation, and discussion on scientific writing. Based on data pertaining to those students’ performance in terms of the normativity, objectivity, and logicality of scientific writing drawn from a previous study by the current author (Deng, Kelly, & Xiao, 2019. The development of Chinese undergraduate students’ competence of scientific writing in the context of advanced organic chemistry experiment course. Chemistry Education Research and Practice, 20, 270–287), alongside data drawn from students’ written texts in reading reflections and on-line discourse related to peer evaluation and discussion, this study claimed that the tasks of reading, peer evaluation, and discussion were seen gradually to lead to the development of Chinese undergraduate students’ greater competence in scientific writing regarding the synthetic experiments of organic chemistry. 相似文献
