EDRS PRICE *Computer Assisted Instruction; Computer Uses in Education; DESCRIPTORS Constructivism (Learning); Educational Technology; Elementary Secondary Education; Internet; Learning Activities; *Spreadsheets ABSTRACT This issue of "TAP into Learning" focuses on technology-assisted learning activities for students, in particular on those that use spreadsheets. Articles include: "Using What Learners Know"; "Activity: Grade 7 and 8 Math, Social Studies and Language Arts"; "Managing Growth: Collaborative Decision-Making in Urban Planning"; "Spreadsheets"; "Getting Started with Spreadsheets"; and "But Aren't Spreadsheets Just for Math?" A sidebar discusses John Locke's "Essay Concerning Human Understanding." The following six principles that make up a framework for constructivism are outlined: "Learners bring unique prior knowledge and beliefs to a learning situation"; "Knowledge is constructed uniquely and individually, in multiple ways, through a variety of authentic tools, resources, experiences and contexts"; "Learning is both an active and a reflective process"; "Learning is developmental. We make sense of our world by assimilating, accommodating, or rejecting new information"; "Social interaction introduces multiple perspectives on learning"; and "Learning is internally controlled and mediated by the learner."

"What did you like about Boston?" Answers ranged from increased amenities like sports teams to a city's livability and architectural uniqueness: "They have sidewalks...All the houses are different. They're not all the same like here." The teacher then asked students to think about their community over time and how it differed from when they were children. What changes had they seen? What were the positive and negative changes? Since these students live in Central Texas, one of the fastest growing regions in the U.S. and home to a number of newly formed high tech companies, they could quite easily note the changes they had seen: more malls, restaurants and movie theaters; more traffic; less familiarity Teachers at Carencro Middle School in Carencro, LA with neighbors; and greater reliance also participated in the Managing Growth activity. on cars.
