Expeditionary Learning in Information Systems: Definition,Implementation, and Assessment

In the natural sciences, collecting, cataloguing, and comparing living specimens have long been a popular, collaborative mode of discovery and learning. New species are discovered, and the relationships between species are theorized. From Aristotle's “History of Animals” to Darwin's “On the Origin of Species”, and beyond, this process of learning through expedition has yielded bountiful knowledge and insights to students of science. In this paper, we propose that expeditionary learning can be applied to a softer science: the field of information systems. In the field of information systems, specimens (information systems) are created by humans, evolving with great speed. Expeditionary learning—where students collaboratively discover, catalog, and compare rapidly evolving information system specimens—is an innovative approach for learners in the IS field, and is effective in increasing IS program visibility and delivering significant, measurable community impact. Our results indicate that learning by expedition has a strong, positive community impact through educating external learners (such as high school and community college students, and the general public), and compares favorably to conventional experiential and service learning styles. Though expeditionary learning does not yield improved course evaluations, we demonstrate that learners’ perceived self‐knowledge and intentions to pursue the subject area are improved.

Classroom Questioning with Immediate Electronic Response: Do Clickers Improve Learning?

A number of studies have focused on how students and instructors feel about digital learning technologies. This research is focused on the substantive difference in learning outcomes between traditional classrooms and classrooms using clickers. A randomized block experimental design involving four sections of undergraduate Operations Management classes was used to determine if clicker systems increase student learning of both quantitative and conceptual material in Operations Management. Learning was measured using the difference between the scores on an entrance examination and the final examination. The findings of this research provide evidence that the use of immediate feedback using a technology like clickers can have a positive impact on student learning as measured by test scores.     

论图像与权力的关系

图像在采集与传播过程中,随处可见权力的影子。没有权力的相伴,图像就无法采集与传播。然而,图像在传播时,控制它的权力会悄悄地发生了滑动和漂移,从制作者手中转移到受众那里,无意中,图像另寻了“新欢”,背叛原来的“东家”。吊诡的是这“新欢”正是“东家”极力向图像推荐的。但是,如果为了防止图像背叛自己,就禁止图像传播,又会因噎废食。图像和权力真是一对充满悖论的欢喜冤家。
