Flashcard: Alternating between Visible and Invisible Identities

This article addresses how my experiences as a black deaf female viscerally and simultaneously shape me. I use the metaphor of flashcards. Flipping over flashcards or “flashing” depicts how certain contexts incite and/or promote the visibility or invisibility of identities, particularly between the familial and educational contexts. Also, I utilize moments from my childhood to narrate alternating reflections of lived experiences (visible) and the theoretical constructs (invisible) that inform and shape these experiences.     

Combining Laboratory Experiments with Digital Tools to Do Scientific Inquiry

This qualitative study investigates the gap between a lab experiment and theory of science. Two groups of 4 students in 2 different classes in 11th grade (15–16 years old) are followed as they process results and experiences from a lab experiment using a digital environment. The experiment is as a part of a larger project about genes and cells, and this study concerns how the digital environment can support students' sensemaking. The study shows how the students only are left with ‘how-to' skills before they engage in collaborative processing supported by their own picture from the experiment. The picture becomes a hub for interactive sensemaking and is extensively used for annotation and discussion. Four elements in the digital support are identified as crucial: an extendable point of reference, facilitation to compare and contrast, a pointer to standard science knowledge, and a structure to guide the students to significant issues. The study identifies where the digital support succeeds and fails in this process of sensemaking from a lab experiment.

Personal Digital Assistants as Point-of-Care Tools in Long-Term Care Facilities: A Pilot Study

This study used both survey and interview questionnaires. It was designed to assess the feasibility, usability, and utility of two point-of-care tools especially prepared with information relevant for dementia care by staff nurses in a small, a medium-sized, and a large nursing home in Florida. Twenty-five LPN or RN nurses were recruited for the study of their use of one of the tools—either a set of pocket cards (used by the control group) or a pocket PC (used by the experimental group). The findings of our study indicate that personal digital assistants (PDAs) can potentially improve long-term care clinicians' effectiveness and efficiency at work, resulting in better patient care for nursing home residents.     

攸关工具、非关工具

大家都知道远程教育的递送模式分为同步、异步与混合三种。做为异步课程的学习者最为单纯,只要会使用浏览器与讨论区就可以了,声音或影像同步的课程就比较麻烦,需要下载并安装特定的应用程序,同时在上课前先要完成注册及测试麦克风、照相机等动作,这些对教师或学习者而言,都是“工具门坎”,除了当事人需要鼓起勇气跨越外,还需要主办单位有很好的技术支持能力。     

An Examination of How a Teacher's Use of Digital Tools Empowers and Constrains Language Arts Instruction

The Common Core State Standards produce a need to understand how digital tools can support literacy instruction. The purpose of this case study was to explore how a language arts teacher's integration of computers and iPads empowered and constrained her and the resulting classroom instruction. Constraining factors included (a) inadequate technological knowledge, (b) expectations of students’ comfort with technology, (c) inappropriate expectations for assignments, and (d) limited conceptions of the purposes of technology. Subthemes related to enhancement included: enhancement of classroom environment, simplicity and sophistication equal innovation and empowerment, combining tools, and digital tools support multimodal communication.

The Complexity of Learning: Exploring the Interplay of Different Mediational Means in Group Learning with Digital Tools

The relationship between the different mediational means for supporting students’ learning with digital tools in science group work in a Norwegian lower-secondary school is examined. Analyses of teacher-student and student-student interactions are located in cultural-historical theory and draw on Galperin’s conceptualisation of learning processes. Findings show that digital tools, task design, peer collaboration, and teacher’s interventions dialectically interplay to shape how learners use mediational means: (1) digital tools are the resources that enable students to explicate their (mis)understandings; (2) compare-and-contrast tasks promote analytical thinking; (3) peers present themselves as resources who promote development of conceptual understanding; (4) the teacher guides learners’ attention towards the potential of the mediational resources, elicits, organises, and structures students’ knowledge. The dialectical interplay of these mediational means creates a system that supports and guides students’ learning.     

《几何画板》从教具变为学具

信息技术在当今社会的各个领域都得到丁广泛应用，在教育领域尤其受到人们的青睐。与以往任何一种先进媒体的应用相比，信息技术的引入，使传统的教育方式发生了更加深刻的变革，甚至可以说是引起了一次革命。计算机辅助教学已经成为广大教育工作者探索、研究和实践的新领域，如何将计算机与传统教学相结合，不断地优化中学数学教学，提高学生的动手能力，需要我们不断地研究、探索和实践。     

Tools and machines

Tools and machines are a big part of children's daily lives. Everywhere they look they can see people using tools and machines to do household chores, to construct buildings, and to travel from place to place. Children, too, use tools when they eat, play, and help Mom and Dad around the house. The understanding of basic tools and simple machines helps children relate to the larger, more complex world of adults.Sandra Drake is the Director/Teacher at the Christ Community Nursery in Lansing, MI.

Web应用程序自动化测试工具

在.NET框架下,研究Web应用自动化测试工具,并给出了设计和实现。该自动化工具包含两个子工具WebTester和WebReplay。前者实现了对测试用例的自动录制、回放,而后者则允许测试人员手工编写测试脚本,进行更为复杂的测试。实现的关键是采用了两个开源的框架Watin和HTMLParser。     

Haptics-Augmented Simple-Machine Educational Tools

This paper describes a unique project using commercial haptic interfaces to augment the teaching of simple machines in elementary school. Haptic interfaces provide a sense of touch and force to the human user from a virtual model on the computer. Since force is central to the teaching of simple machine, we believe that the use of haptics in virtual simple-machine simulations has the potential for deeper, more engaging learning. A software has been developed and is freely available on the Internet. HTML tutorials have been developed to support these haptics-augmented software activities in the teaching and learning of simple machines in elementary school. The pilot study results are reported, which yielded positive feedback and suggestions for project improvement from elementary school students and teachers.

CILT2000: Community Tools

Community tools are technologies designed to foster social processes of learning through active inquiry, project-based learning, and related collaborative pedagogical approaches. Current research and development in this field are moving from generic tool design towards the development of sociotechnical systems that address learning in relation to specific domains of knowledge or activity and social issues such as equitable access to learning opportunities.
