Digitizing IKS: Epistemic complexity, datadiversity & cognitive justice

In contemporary African societies where multiple systems of knowledge coexist, and the use of informatics is becoming increasingly widespread, conventional perspectives drawn from cultural anthropology, environmentalism, development studies and intellectual property rights are insufficient guides to thinking about the digitization of indigenous knowledge. Taking an interdisciplinary approach, three moments in South African knowledge dynamics are used to probe some of the ontological, epistemological, and performative implications of science/IKS interaction in the design and construction of archives and databases of local plants. Twenty-first century databases of indigenous African medico-botanical knowledge need to assure that it is recontextualized historically and socially; that its multiplicity, visuality, and orality are retained; and that “articulation work” is done to make sure that design choices and use are cognitively just.

Teaching and Learning Physics in a 1:1 Laptop School

1:1 laptop programs, in which every student is provided with a personal computer to use during the school year, permit increased and routine use of powerful, user-friendly computer-based tools. Growing numbers of 1:1 programs are reshaping the roles of teachers and learners in science classrooms. At the Denver School of Science and Technology, a public charter high school where a large percentage of students come from low-income families, 1:1 laptops are used often by teachers and students. This article describes the school’s use of laptops, the Internet, and related digital tools, especially for teaching and learning physics. The data are from teacher and student surveys, interviews, classroom observations, and document analyses. Physics students and teachers use an interactive digital textbook; Internet-based simulations (some developed by a Nobel Prize winner); word processors; digital drop boxes; email; formative electronic assessments; computer-based and stand-alone graphing calculators; probes and associated software; and digital video cameras to explore hypotheses, collaborate, engage in scientific inquiry, and to identify strengths and weaknesses of students’ understanding of physics. Technology provides students at DSST with high-quality tools to explore scientific concepts and the experiences of teachers and students illustrate effective uses of digital technology for high school physics.     

Blind spot detection using vision for automotive applications

This paper describes a vision-based system for blind spot detection （BSD） in intelligent vehicle applications. A camera is mounted in the lateral mirror of a car with the intention of visually detecting cars that are located in the so-called blind spot and cannot be perceived by the vehicle driver. The detection of cars in the blind spot is carried out using computer vision techniques, based on optical flow and a double-stage data clustering technique for robust vehicle detection.     

“工学结合”下计算机软件开发教材改革初探

在国家大力发展职业教育的大形势下,职业教育的规模在扩大。如何提高高职教育的教学质量,除了好的教师、教学方法、教学工具,教材也是一个重要方面。教材是教师授课和学生学习的重要工具。特别是在提倡"工学结合"的情况下,如何编写一本好的、适应高职教学的教材也是在高职教学改革中所要注意到的问题。本文就"工学结合"下计算机软件开发教材编写改革提出一些拙见。
