This study investigates the usability of print and online video instructions for computer tasks. Usability tests, comprehension tests, and questionnaires were collected from participants, and 4 areas of usability were analyzed: effectiveness, retention, satisfaction, and preference. Findings show marginal differences between the 2 mediums, except in terms of user satisfaction and instruction length. This research helps technical communicators better understand the affordances, or potentials and limitations, of print and video instructions.  相似文献

This article explores the ways that the discourse of usability might support a socially oriented pedagogy within technical communication. Specifically, it explores two approaches to usability—user-centered design and distributed usability—and suggests that the conversation between these approaches can ground socially responsive discussions of technology and technical communication. As such, the discourse of usability provides a field-specific means to address increasing calls for socially situated pedagogies within the field of technical communication.  相似文献

This study investigated to what extent virtual internships in teacher education were able to reduce Preservice Teachers’ (PSTs) professional anxiety. Simultaneously, this study investigated how virtual internships in blended learning environments were evaluated by PSTs in terms of technological, social and educational affordances. PSTs followed virtual internships during two different Educational Pedagogy Master’s courses (27 and 16 participants) in a teacher education programme. A mixed methods design was employed, consisting of pre- and post-test questionnaires, a focus group interview and individual interviews. A significant decrease was found in PSTs’ professional anxiety after having followed Virtual Internship 2. PSTs reported they obtained a more realistic image of teaching and felt better prepared for teaching in practice. Furthermore, regarding technological affordances, system usability was considered between acceptable and good. Concerning social affordances, PSTs appreciated collaboration within the virtual internships. As an educational affordance, it appeared that learning from videos with authentic classroom events is a good preparation for the professional teaching context. According to the PSTs, the scenarios within virtual internships could be improved in terms of authenticity and personalisation by offering more details and background information. The results of this study imply that virtual internships can be useful assets for teacher education.  相似文献

We designed and piloted a technical communication course for software engineering majors to take concurrently with their capstone project course in software design. In the pilot, one third of the capstone design course students jointly enrolled in the writing class. One goal of the collaborative courses was to use writing to improve the usability of students’ software. We studied the effects of writing on students’ user‐centered beliefs and design practices and on the usability of their product, using surveys, document analyses, expert reviews, and user test results. When possible, we compared the usability processes and products of teams who did and did not take the writing class. Our findings suggest that the synergy of this interdisciplinary approach effectively sensitized students to user‐centered design, instilled in them a commitment to it, and helped them develop usable products.  相似文献

Assessment of clinical skills is a critical element of undergraduate medical education. We compare a traditional approach to procedural skills assessment – the Objective Structured Clinical Examination (OSCE) with the Integrated Performance Procedural Instrument (IPPI). In both approaches, students work through ‘stations’ or ‘scenarios’ undertaking defined tasks. In the IPPI, all tasks are contextualised, requiring students to integrate technical, communication and other professional skills. The aim of this study was to explore students’ responses to these two assessments. Third‐year medical students participated in formative OSCE and IPPI sessions on consecutive days. Although performance data were collected in both assessments, quantitative data are not presented here. Group interviews with students were conducted by independent researchers. Data were analysed thematically. The OSCE and the IPPI were both valued, but for different reasons. Preference for the OSCE reflected the format of the summative assessment. The IPPI was valued for the opportunity to practise patient‐centred care in a simulated setting which integrated technical, communication and other professional skills. We posit that scenario‐based assessments such as the IPPI reflect real‐world issues of patient‐centred care. Although the limitations of this study prevent wide extrapolation, we encourage curriculum developers to consider the influence of assessments on what and how their students learn.  相似文献

The current study investigated how item formats and their inherent affordances influence test‐takers’ cognition under uncertainty. Adult participants solved content‐equivalent math items in multiple‐selection multiple‐choice and four alternative grid formats. The results indicated that participants’ affirmative response tendency (i.e., judge the given information as True) was affected by the presence of a grid, type of grid options, and their visual layouts. The item formats further affected the test scores obtained from the alternatives keyed True and the alternatives keyed False, and their psychometric properties. The current results suggest that the affordances rendered by item design can lead to markedly different test‐taker behaviors and can potentially influence test outcomes. They emphasize that a better understanding of the cognitive implications of item formats could potentially facilitate item design decisions for large‐scale educational assessments.  相似文献

Using video as a mode of data generation in research involving young children and their teachers has become a more common practice in educational research. Digital video recordings provide the opportunity to capture the complexity of interactions that occur between people, time, space and objects, however, working with this methodology and form of data can be complex and challenging. This paper focuses on the use of video as a methodology to understand teachers’ tacit knowledge of practice that supports young children’s oral language. This study explores four specific viewpoints that have been employed to investigate teachers’ practice: (1) camera, (2) teacher, (3) researcher and (4) peers. From our analysis of the affordances of the differing viewpoints, we propose that what can be ‘seen’ is directly impacted by the understandings of those involved in the research process in relation to data capture, viewing and analysing the data. We argue that these viewpoints are not neutral or mutually exclusive rather they should be considered complementary and supplementary in building a comprehensive understanding of teachers’ tacit knowledge of literacy practice.  相似文献

ABSTRACT

This article reports on an effort by the authors to use usability testing as a component of online teacher training for their multimajor technical communication course. The article further explains the ways in which program administrators at other institutions can create their own usability testing protocols for formative online teacher training in course design and in principles of user-centered design.  相似文献

This paper reports the results of a three-stage usability test of a modeling tool designed to support learners’ deep understanding of the impacts of climate change on ecosystems. The design process involved repurposing an existing modeling technology used by professional scientists into a learning tool specifically designed for middle school students. To evaluate usability, we analyzed students’ task performance and task completion time as they worked on an activity with the repurposed modeling technology. In stage 1, we conducted remote testing of an early modeling prototype with urban middle school students (n = 84). In stages 2 and 3, we used screencasting software to record students’ mouse and keyboard movements during collaborative think-alouds (n = 22) and conducted a qualitative analysis of their peer discussions. Taken together, the study findings revealed two kinds of usability issues that interfered with students’ productive use of the tool: issues related to the use of data and information, and issues related to the use of the modeling technology. The study findings resulted in design improvements that led to stronger usability outcomes and higher task performance among students. In this paper, we describe our methods for usability testing, our research findings, and our design solutions for supporting students’ use of the modeling technology and use of data. The paper concludes with implications for the design and study of modeling technologies for science learning.  相似文献

This paper reports on a case study of English as a second language (ESL) vocabulary learning that examined a group of Grade 4 students’ mobile learning experiences of bridging in-class and real-life vocabulary learning mediated by a mobile learner-generated content (m-LGC) tool. This study was premised on the proposed framework of mobile vocabulary learning from an ecological perspective using the concept of affordances, taking the topic of “Food” as an example. Data collection included learning logs created by students and a questionnaire about students’ perceptions of the m-LGC tool for vocabulary learning. The results revealed four types of affordances of the m-LGC tool that the learners perceived and acted on in real life outside the classroom, namely: vocabulary form-meaning mapping, consolidating vocabulary by productive use, vocabulary revision and social affordance. The students’ perceptions of the m-LGC tool for vocabulary learning were positive. This study shows that the various affordances helped students in applying newly learned words to real-life contexts. Social affordance provided the social contexts for communication via peer interaction, vocabulary expansion as well as the creation of a learning community.  相似文献

Technology provides the means to create useful learning and practice environments for learners. Well‐designed cognitive tutor systems, for example, can provide appropriate learning environments that feature cognitive supports (ie, scaffolding) for students to increase their procedural knowledge. The purpose of this study was to conduct a series of usability tests of a dialogue‐based design framework for the presentation of domain knowledge and assess how it can be used to actively engage learners in learning about research methods. Three formal usability assessments and an instructor adoption assessment were conducted during the development of the tutoring system. Each usability assessment employed diverse data collection methods to ensure broad and in‐depth coverage of findings. The findings revealed that the dialogue metaphor enabled natural and participatory interactions between the system and users. The feedback prompts or hints and support resources provided opportunities for learning during the process of problem solving. Future research to extend the support of usability assessments is also discussed.  相似文献

Technical communicators have developed different methodologies for evaluating the effectiveness of their work (whether the information can be used by the intended audience), such as editing, usability testing, and determining the value-added. But, as vastly differing assessments of the same professionally produced technical communication products suggest, at least three broad value systems underlie the assessment practices: characteristic-based (assessing against a set of criteria), task-based (assessing users' observed ability to perform tasks), and results-based (assessing the contribution to the publisher, usually in financial terms). The systems do not overlap with one another; rather, they embody different values about what makes technical communication effective. The most complete form of assessment may involve multiple assessment approaches and triangulated results.  相似文献

Although researchers have reported positive effects on teacher learning from observing published video, teachers’ own video, and their colleagues’ video, very few professional development programs have integrated all three types of video to improve teacher learning. In this study, we examined the affordances and challenges of the three types of video when they were used in a Problem-Based Learning professional development program, drawing upon multiple data sources from 26 K-12 science teachers. We present a case study to illustrate how one teacher might learn from each type of video, and conclude with recommendations for using video in professional development.  相似文献

Although music software has become increasingly affordable and widely adopted in today’s classrooms, concerns have been raised about a lack of consideration for users’ needs during the software development process. This paper examines intra- and inter-sectoral communication pertaining to software development and music education to shed light on the improvement of the educational affordances for music software in classroom teaching and learning. Semi-structured interviews with music software developers (n = 3) and music teachers (n = 15) are used to gain insights into how to enhance the educational affordances of music software. The findings of this study fill a gap in the literature by detailing the knowledge exchange required to effectively develop music education software. Improving the synergy between the knowledge bases of software development and music education could enhance novel educational affordances, providing music teachers with the opportunity to develop new, pedagogically sound music teaching and learning activities.  相似文献

The contemporary era provides several challenges which extend from the reconstitution of an innovative knowledge domain and curricula to candidate learning platforms that support online course delivery methods. Educators and scholars on these demands have recently started to rethink alternative ways for the assimilation of the experiential knowledge in three-dimensional (3D) technologically advanced environments, like 3D multi-user virtual worlds. In spite the widespread dissemination and proliferation of novel educational implications by utilizing 3D multi-user virtual worlds combined with the 2D interface of LMS (Learning Management Systems) and the assessment of the effectiveness based on the online course delivery method in a long-term usability is still absent from the international academic literature. This study presents interoperability issues focused on the utilization of the virtual world Open Simulator (Open Sim) in conjunction with Sloodle (Simulation Linked Object Oriented Dynamic Learning Environment) as a free plug-in module. The evaluation of this online learning process according to an empirical research method became possible with the assistance of ninety-five (95) students by two different academic sectors that participated in this project and measured the capabilities and instructional affordances of this platform. The evaluation process was focused on four multi-dimensional parameters (psychological-pedagogical, technical-operational, organizational-financial, and socio-cultural). The study findings based on students’ experiences revealed that both platforms could be sufficiently connected as a unique platform which can increase the users’ learning abilities. This “hybrid” platform can adequately convert the ordinary multi-user virtual world of Open Sim and Sloodle in a common “incubator” of knowledge for online courses at university level. At the end, the instructional affordances and implications for future-driven directions are also discussed.  相似文献

This study explores the usability of community college websites. The value of a college’s website has been well established, as have accepted standards for basic website design. However, current usability standards are less clear and in various stages of acceptance. To consider this question, standards of usability were applied to all community college websites in Alabama. Websites were assessed for usability by use of a modified instrument that includes sample usability task scenarios provided by Cornell University’s Web Accessibility Toolkit and includes items from a similar exploration conducted on a national sample of colleges and universities (Meyer, 2008). The existence of specific website content tailored to prospective part-time students and the use of social media by the Alabama community colleges was also examined. Results show that most colleges meet minimum standards for usability.  相似文献

The nature of knowledge and how it is developed have been debated in philosophy and research for centuries. In the literature on teachers’ knowledge, two perspectives have been particularly visible. One perspective stresses cognitive processes and deliberate knowledge acquisition. Another perspective stresses the situated nature of teachers’ learning and knowledge development through awareness. This theoretical article proposes that uniting both epistemological perspectives is beneficial for developing teachers’ contextualized knowledge of how to teach at all phases of career development, and especially early on. In so doing, action and reflection are positioned as central to the development of teachers’ knowledge, and affordances from both the deliberate and the aware perspectives are articulated. Specifically, this article explains why uniting the two perspectives supports better sense-making, more refined instructional planning, and more responsive teaching, before offering a united reflection model. These processes are then discussed in the context of video coaching interventions for early-career teachers. After presenting a blueprint for video-based reflection and key design features that could support teachers’ learning, important differences compared to other reflection models are discussed and implications for (the design of) teachers' professional development based upon this united perspective are presented.

This article investigates why students reported liking a student-driven learning design better than a highly guided design despite equivalent gains in knowledge assessments in both conditions. We created two learning designs based on the distinction in the literature between student-driven and teacher-led approaches. One teacher assigned each of her two 5th-grade classes to one design (n = 52); both designs addressed the mathematical concepts for the same amount of time. Data were collected using written assessments, surveys, and video. Students in both classes improved equivalently on assessments. On surveys, students in the student-driven condition were significantly more positive about learning. Video was coded to examine why students were more positive in the student-driven design. This analysis showed students engaging more frequently with data in discussing strategies, questioning peers, and aligning outcomes with prior experiences. We trace the association between students’ positive responses to learning and richer engagement in mathematical practices to specific features of the student-driven design. Furthermore, we reject competing explanations (e.g., amount of off-task behavior or adult intervention). We conclude that designing learning opportunities that promote mathematical practices affords opportunities to cultivate students’ disciplinary interest. We discuss implications for teachers and curriculum designers who are responding to new mathematics standards.  相似文献
