Science instruction is typically highly dependent on visual representations of scientific concepts that are communicated through textbooks, teacher presentations, and computer-based multimedia materials. Little is known about how students with visual impairments access and interpret these types of visually-dependent instructional materials. This study explored the efficacy of new haptic (simulated tactile feedback and kinesthetics) instructional technology for teaching cell morphology and function to middle and high school students with visual impairments. The study examined students’ prior experiences learning about the cell and cell functions in classroom instruction, as well as how haptic feedback technology impacted students’ awareness of the 3-D nature of an animal cell, the morphology and function of cell organelles, and students’ interest in the haptic technology as an instructional tool. Twenty-one students with visual impairment participated in the study. Students explored a tactile model of the cell with a haptic point probe that allowed them to feel the cell and its organelles. Results showed that students made significant gains in their ability to identify cell organelles and found the technology to be highly interesting as an instructional tool. The need for additional adaptive technology for students with visual impairments is discussed.This material is based upon work supported by the National Science Foundation under Grant Numbers 0354578 and 0411656 相似文献

AbstractThe augmentation of easily accessible and affordable information and communication technology (ICT) for instructional purposes was the key objective which made the study reported on relevant to most financially constrained higher education institutions (HEIs). The aim of the study was to investigate the feasibility of augmenting the entrenched face-to-face instructional modes at a resource-constrained peri-urban satellite campus of the University of Namibia with some of the latest but affordable mobile technology applications. The study made use of a survey, face-to-face interviews, and a focus group discussion which dealt with the broad themes such as skills and competences, attitudes, motivation, and access to the internet. The findings revealed very pertinent contextual themes such as psycho-sociocultural dimensions associated with the usage of social media. Moreover, the motivation level among lecturers was found to be significantly low, and this was largely attributed to resource constraints. The research recommends some pragmatic solutions to augment the traditional modes of delivery with simple but creative ICT innovations. 相似文献

This study investigated the impact of a self-regulatory tool, the Instructional Planning Self-Reflective Tool (IPSRT), on
preservice teachers' performance, disposition, and self-efficacy beliefs regarding systematic instructional planning. Participants
enrolled in an introductory educational technology course were taught how to develop an instructional plan as part of the
course. An experimental group was provided with instruction on how to use the IPSRT while engaging in instructional planning.
Results indicated that the experimental group demonstrated greater skill acquisition, showed more positive disposition, and
reported higher perceived instrumentality of instructional planning. In terms of self-efficacy, no significant differences
were found between the two groups. However, further analyses revealed that participants who were initially high in self-efficacy
reported significantly lower self-efficacy following the tool intervention; in contrast, participants initially low in self-efficacy
showed significantly higher self-efficacy following the tool intervention. Findings are discussed from a social-cognitive
perspective. 相似文献

Students have conceptions about the relationship between instructional interventions and learning or, in other words, students have instructional metacognitive knowledge. In this study, the efficiency of instructional interventions has been investigated as a specific object of students' instructional metacognitive knowledge. By means of a survey, conceptions about the efficiency of various instructional interventions of 488 freshmen in educational sciences and psychology have been investigated. Two research questions directed this exploratory study: (1) How do students assess the efficiency of instructional interventions; and (2) Do differences in gender, educational background, and/or subject of study affect evaluations of the efficiency of instructional interventions. Results show that respondents regard regular instructional interventions at the university directed toward, or supporting, surface-level processing and reproduction to be highly efficient. The use of technology is conceived as inefficient by these students. The limited number of differences between groups of students also suggests students' conceptions to be both consistent and robust.The study illustrates the need to investigate instructional metacognitive knowledge as distinct from other forms of metacognitive knowledge, and raises questions about the major components and structure of instructional metacognitive knowledge and individual differences in it. The findings suggest the need for the elaboration of a framework to describe instructional interventions. 相似文献

The Instructional Systems Technology (IST) program at UNC Charlotte develops instructional technologists who are grounded in instructional technology foundations, principles, theories, applications, and current trends. The program also provides opportunities for students to integrate different forms of technology to enhance teaching and learning. In this article, we introduce the IST program, its real‐world HPT course, and its learning leaders forum that brings industry leaders and the IST program together to discuss the trends in the field. 相似文献

This study sets forth an eight-variable causal model describing the spread of instructional innovations among individual faculty members. The model is tested by examining the diffusion of a particular innovation—self-instructional materials—among the faculty of sixteen medical schools, with data provided by faculty survey. The causal model as initially posited is found not to fit the data well; modifications of the model are found to conform more closely. The primary measure accounting for observed variance in faculty innovation behavior is frequency of communication with colleagues about the instructional process. 相似文献

The survey Performance Standards for In-service Teachers is widely used to help describe teacher skills relating to instructional technology for assessment or planning of professional development. It is based on the six constructs of the National Educational Technology Standards for Teachers, and though used broadly in a variety of contexts, it does not appear to have undergone significant independent evaluation of its psychometric properties. Our analysis found that all six subscales possessed strong internal consistency (all α > 0.93). A subsequent confirmatory factor analysis supported both its current six-factor structure as well as a more parsimonious one-factor model. 相似文献

There is, no doubt, untapped potential in using technological tools to enhance the understanding of science concepts. This
study examines the potential by observing 7th and 8th grade middle school students’ (n = 23) use of portable data collection devices in a nine-week elective class, Exploring Technologies. Students’ use of the data collection devices and subsequent interactions were traced through audiocassette and videocassette
recordings, field notes, and student artifacts. The culminating activity for the course was a scientific investigation that
required students to use the technologies to answer student-selected research questions. To illustrate the use of technology
as a mediatory tool, an inquiry investigation of three student groups is described. In examining the three groups of middle
school students the researchers encountered specific evidence of technology maximizing students’ science learning. The students
were able to use the portable data collection devices in their investigations as they discussed scientific ideas related to
temperature and heat. The study’s findings indicated that the three student groups were able to use the tools to conduct scientific
inquiry and engage in scientific discourse. Further research on instructional approaches that allow students to develop expertise
by using technology as tools to construct knowledge about complex phenomena is encouraged. 相似文献

The researchers examined responses from 862 faculty members at 38 institutions nationwide using the blackboard Learning Management System (LMS) to supplement their face-to-face instruction. The four research questions addressed the primary uses that faculty make of blackboard, perceptions that faculty have of how certain blackboard features enhance or elevate (or might enhance or elevate) their assessment of student work and instructional capabilities, and how faculty use of blackboard might positively affect the psychosocial climate within the face-to-face classroom setting. Additional analysis sought to identify the factors that predict use and positive perception of blackboard as a supplement to face-to-face teaching activities. The results indicate that faculty primarily used blackboard as a course management/administration tool to make course documents available to students and manage course grades. Few faculty used blackboard for instructional or assessment purposes, and even fewer utilized blackboard to foster a more positive sense of community within their face-to-face classes. Faculty attitudes, on the whole, were positive when it came to the classroom management functions of blackboard, but neutral or otherwise undecided in terms of its instructional or psychosocial benefits. The main factor in determining blackboard usage—whether for course administration or instructional purposes—was experience with the tool. In addition, women had more positive attitudes than men did in terms of blackboard's potential to enhance classroom management and foster a positive relational climate. Limitations of the study and suggestions for future research are discussed before concluding. 相似文献

The purpose of this study was to examine teachers’ perceptions of their school environment in terms of factors that enhance or prohibit the use of instructional technology. The study also investigated whether the technology implementation environment varied for schools at different locations and different levels. Both quantitative and qualitative data indicated that the most serious problem in K–12 technology implementation was time constraints, followed by technical problems that could not be taken care of in a timely manner. Suburban schools had the most favorable conditions in all aspects of technology implementation support. No significant differences were found between school levels. 相似文献

While research on and development of evidence‐based instructional practices (EBIPs) in STEM education has flourished, implementation of these practices classrooms has not been as prolific. Using the teacher‐centered systemic reform model as a framework, we explore the connection between chemistry instructors’ beliefs about teaching and learning and self‐efficacy beliefs, and their enacted classroom practices. Postsecondary chemistry faculty present a unique population for the study because of their role in teaching prerequisite courses, such as general and organic chemistry, which are key to many science major fields. A measure of teacher beliefs and self‐efficacy was administered to a national survey of postsecondary chemistry faculty members. Instructional practices used in a chemistry course were also collected via self‐report. While instructional practices were not directly observed, a cluster analysis of our data mirrors patterns of instructional practices found in observation‐based studies of chemistry faculty. Significant differences are found on teacher thinking and self‐efficacy measures based on enacted instructional practices. Results support the hypothesized connection between beliefs and instructional practice on a larger scale than in previous studies of this relationship, bolstering the evidence for the importance of this relationship over previously criticized results. These results present a call for reform efforts on fostering change from its core, that is, the beliefs of those who ultimately adopt EBIPs. Dissemination and design should incorporate training and materials that highlight the process by which faculty members interpret reformed practices within their belief system, and explore belief change in the complex context of education reform. 相似文献

High-quality measures of instructional practice are essential for research and evaluation of innovative instructional policies and programs. However, existing measures have generally proven inadequate because of cost and validity issues. This paper addresses two potential drawbacks of survey self-report measures: variation in teachers’ interpretation of response scales and their interpretation of survey questions. To address these drawbacks, researchers tested out use of “anchoring vignettes“ in teacher surveys to capture information about teaching practice, and they gathered validity evidence in regard to their use as a tool for adjusting teachers’ survey self-reports about their instructional practices for research purposes, or potentially to inform professional development. Data from 65 teachers in grades 4-9 responding to our survey suggested that vignette adjustments were reliable and valid for some instructional practices more than others. For some instructional practices, researchers found significant and high correlations between teachers’ adjusted survey self-rating, through use of anchoring vignettes, and previous observation ratings of teachers’ instruction, including ratings from several widely-used observation rubrics. These results suggest that anchoring vignettes may provide an efficient, cost-effective method for gathering data on teachers’ instruction. 相似文献

This study investigated classroom practices of 38 teachers enrolled in university masters' degree programs in educational technology and in other areas of education. The classroom practices related to five key concepts associated with educational technology: (a) learner-centered instruction, (b) instructional design, (c) media and technology, (d) assessment, and (e) instructional alignment. Teachers rated their frequency of use of desirable practices in these five areas on a 30-item Likert type survey. In addition, one class of students per teacher rated its own teacher's frequency of use of the practices on 20 items parallel to items on the teacher survey. The mean overall rating across all teachers for the classroom practice items was very close to Often, or 4.0, on the 5-point scale. There were few reported differences between the teachers enrolled in educational technology programs and those enrolled in other education programs. Student ratings indicated less frequent teacher use of the desirable practices on 16 of the 20 common items, with significantly lower student ratings on 8 of these items. However, there was strong teacher-student agreement on several other comparisons.The study reported in this article was conducted as a doctoral dissertation at Arizona State University. 相似文献

‘Thinking schools’ will be sites of learning for everyone declared the Singapore Prime Minister, Goh Chok and Minister of
Education Teo Chee Hean’s in 1997 also spoke on the model of’ ‘thinking schools, learning nation’. Gardner’s model was used
for the thinking school model in Singapore, in order to develop critical and creative thinking in students. This was to be
done with the use of instructional technology as an enabling tool using a diversity of approaches including integrated project
work. This paper reports on how one school went about changing approaches to teaching and learning by implementing integrated
project work as a way of integrating the content areas of the curriculum, mathematics and science through English language,
supported by the tools of instructional technology. 相似文献

As it has been shown that teachers of social studies content are less likely than teachers of other content areas to utilize technology in their classroom, this study focuses on one instructional technology coordinators’ beliefs towards technology, instruction, and students and how these beliefs impacted how technology was utilized during a technology-enriched community history project with a group of fourth-grade students. It was determined that the instructional technology coordinators’ beliefs included the following: (a) technology should serve as a tool and should be seamlessly integrated into the curriculum; (b) the teacher should construct meaningful experiences that allow students to become engaged in the learning process; however, before guiding student discovery, the teacher needs to explicitly teach basic technological skills; (c) and all students are able to learn and are capable of engaging in independent problem solving and critical thinking at some level. Her beliefs manifested themselves daily, particularly in the way that she approached instruction and integrated technology seamlessly into the curriculum. Through this study, it was found that the technology coordinator's beliefs toward technology, instruction, and her students directly impacted how technology was used in her classroom. 相似文献

当技术遇到教育,它们以怎样的方式互动?教育技术的演化机制又是以怎样的方式运行?文章借用让.皮亚杰研究发生认知论的方法,试图解释教育与技术相互作用的方式以及教育技术的演化机制,提出教育技术是主体的教育与客体的技术通过同化和调节过程,不断地从一个较初级的教育技术的格局转化为一个较复杂的格局。它的演化机制是通过"教育技术化"与"技术教育化"两个关键路径实现的。通过研究可以得出这样的启示:技术应用于教育必须充分考虑到教育的复杂性,游离于教育系统之外,无论多么先进的技术都无法发挥其应有的功效;同时教育作为发展主体应特别注意把握好在教育与技术互动过程中"调节"时机的浮现,勇于创新与变革教育系统,以适应新技术带来的机遇和挑战。 相似文献

The purpose of this study was to identify instructional strategies used by teachers to support technology integration. In addition, relations between types of computer applications and teachers' classroom practices were examined. Data were direct observation results from 143 integration lessons implemented in schools receiving federal technology grants. Results reflect use of student-centered practices such as teacher as a facilitator, project-based learning, and independent inquiry. Furthermore, this study revealed that classroom practices tend to be more student-centered when students use the computer as a learning tool such as the Internet, word processing, and presentation software. Conversely, drill and practice software showed a dissimilar pattern. 相似文献

Community college faculty development programs assist faculty in the development of quality curricula, using current and expanding teaching technologies. The first step in helping faculty reach their respective goals is to help them articulate their instructional needs. Eighteen faculty members participated in this study, using a personal in-depth interview as the research method. Several implications for community college faculty and administration resulted from this study including: the need to emphasize information literacy, the faculty as lecturers who want to use technology as a means of enhancing that lecture, the need for more time to accomplish their instructional ideas, the need for help to incorporate technology in the classroom themselves, and the desire for training classes that fit their time schedules and location. 相似文献
