- Abstract: Many systems involve some type of time keeping. By using 555 integrated circuit in astable state it is easy to design and make accurate and cheap timing circuit (e.g., alarm circuit, counting circuit, sensing circuit, etc.) The working principle of this 555 IC in astable state is supported by the following formulae: Timing period, Timing=(R1+2R2) C/1.44.

- Abstract: Active Lessons are engaging, technology-based, student-centered (pupil-centered) learning activities designed by teachers using PowerPoint (or other presentation tool). The idea is to empower teachers to easily create technology-based activities that draw upon variety of existing and new digital resources from internet, repositories of learning objects and other sources, and require students to use technology and create artifacts demonstrating their understanding. This idea partially challenges WebQuest approach and proposes that instead of getting teachers to design web sites, more effective strategy would be to use a presentation tool to design in more productive way. Active Lessons are technologically simple because PowerPoint is used for design and there is no need to struggle with technicalities of web publishing. With reduction in technicalities teachers can concentrate on pedagogy. The central hypothesis in this proposal is that if teachers develop understanding of technology-supported pedagogy, technicalities will synch in naturally through experience and emerging needs.

- Abstract: In this simulation you will investigate relationships between voltage, resistance, and current that exists in an electric circuit. You will adjust voltage of the power source and resistance of the resistor and then use digital multimeter to obtain measurements. Then you will record these measurements and look for relationships that exist between voltage, resistance, and current.

- Abstract: This workshop explores how contemporary technology tools empower students and teachers to engage in highly creative and reflective tasks to organize and present information, and express emotions, ideas and knowledge through multimedia creations known as digital stories. Digital storytelling is increasingly becoming popular in schools all over the world as an engaging technology-based learning strategy. In this workshop, the participants will be exposed to powerful user-friendly and cost-free technology tools and techniques for digital storytelling.

- Abstract: A learning object is best described as a representation designed to be reused in different educational contexts. In this page you will references to my papers and examples of various learning objects develop either by my self or by my students. Learning objects might reside in digital repositories, ready to be located and utilized by those involved in educational activities (e.g., teachers and students). They address: (a) key concepts from disciplines, in visual and often interactive ways not permitted with previous technologies, for sharing of socio-historical heritage of humanity (our knowledge), (b) information and data that can be useful in the context of developing disciplinary-specific thinking, culture of practice, spirit of inquiry, theoretical knowledge and information work, (c) presentation of small, instructional sequences and demonstrations delivering encapsulated descriptions of some aspects of subject matter which can support learning processes by providing âjust-in-timeâ information, (d) simulations of key equipment, tools and processes from a discipline to enable development of deep understanding of artifacts used in a culture of practice. My immediate intention is to empower education professions with digital material which they can use to create a spectrum of educational activities.
