Compost Office
Yard and food wastes make up nearly one-third of the waste stream in the United States, most of which gets put in landfills or incinerated. Did you know that by simply combining some basic elements — organic waste, soil, water, and air — you can create ideal conditions for recycling these wastes naturally? This interactive activity from Keep America Beautiful, Inc. details what composting is and the roles that soil microbes, oxygen, and moisture play in this process. A game challenges users

The Diver Project: Interactive Digital Video Repurposing
The digital interactive video exploration and reflection (Diver) system lets users create virtual pathways through existing video content using a virtual camera and an annotation window for commentary. Users can post their Dives to the WebDiver server system to generate active collaboration, further repurposing, and discussion. Although our current work focuses on video records in learning research and educational practices, Diver can aid collaborative analysis of a broad array of visual data re
La natura della mediazione offerta dai sistemi basati su micromondi all’apprendimento della matema
In questo articolo prenderemo in esame il sistema ARI-LAB che abbiamo realizzato per sostenere gli alunni nello sviluppo di capacità nel problem solving aritmetico e cercheremo di descrivere alcune caratteristiche che questo software rende disponibile con il fine di valutarne le potenzialità sul terreno didattico. Nel fare ciò assumeremo due riferimenti: da una parte l'analisi della natura del sapere coinvolto nel problem solving aritmetico, descritta nella prima parte di questo lavoro, dall'
La natura della mediazione offerta dai sistemi basati su micromondi all’apprendimento della matema
Questo lavoro analizza il ruolo che ambienti basati sull’uso del calcolatore, ed in particolare i micromondi, possono assumere nelle attività di insegnamento e apprendimento di conoscenze matematiche.
Il lavoro parte dallo studio di alcuni risultati significativi che si sono avuti in questo campo a livello internazionale. Tale studio viene utilizzato come quadro di riferimento per situare e analizzare una ricerca specifica che abbiamo svolto in questo settore.
Tale ricerca riguarda la proge
Air - Is It Really There?
By watching and performing several simple experiments, students develop an understanding of the properties of air: it has mass, it takes up space, it can move, it exerts pressure, it can do work.
Strange matter : discover the secrets of everyday stuff!
Are your students familiar with the development and uses of foams and plastics? What about buckyballs and magneto-rheological fluid? At this animated site, a companion to a traveling science center exhibition, students in grades 5-8 can explore materials science. Four sets of activities address, respectively, the structure, properties, processing, and performance of materials. Kids are the guides for these activities, which come equipped with sound effects, video clips of scientists, games, and
Materials smackdown
Who will best survive compression: Plastica (acrylic) or the Crystal Crusader (glass)? What about Incredible Bulk (polystyrene) or Mr. Cheese (mozzarella)? In this materials science activity, students experience four of these sorts of matches where pairs of materials are crushed in a virtual machine. Before and after each match, students learn about the properties of the materials that they are testing. Before watching the crushing, students can read brief histories and summations of the strengt

Affidavit and Flyers from the Chinese Boycott Case
This site introduces students to one instance in which immigrants overcame the ramifications of the Chinese Exclusion Act of 1882 through the U.S. judicial system. This lesson correlates to the National History Standards and National Standards for Civics and Social Sciences. It also has cross-curricular connections with history, government, language arts, and math.

Structural Equation Modeling Assessment of Key Causal Factors in Computer Crime Victimization
This dissertation empirically assesses a computer-crime victimization model by applying Routine activities theory. Routine activities theory is arguably, as presented in detail in the main body of this study, merely an expansion of Hindelang, Gottfredson, and Garofalo’s lifestyle exposure theory. The components of routine activities theory were tested via structural equation modeling to assess the existence of any statistical significance between individual online lifestyles, the levels of com
The Rhetorical Situations of College Writing Assessment: Exigence, Constraints and Audience in the E
While literacy educators in the field of composition studies have traditionally
approached the issue of writing assessment from a classroom perspective that emphasized
assessment’s role in the processes of teaching and learning, recent trends in American public policy have made data gathered from educational assessment the basis for arguments of education policy reform. In particular, during the past 15 years, a loose affiliation of advocacy groups known as the P-16 movement has sought to use
Possible Predictive Factors for the Greater Johnstown School District’s Pennsylvania System of Sc
Relative to Curriculum-Based Assessment (CBA) and the Pennsylvania System of School Assessment (PSSA), this study sought to determine whether a school district’s CBA reading scores were predictors for the PSSA reading scores for a grade-level cohort of students. Those CBA reading scores were collected in fourth through seventh grades; while the PSSA measure was a scaled score earned on the eighth grade reading measure. The sample included 268 eighth grade students who were roughly 48% male,
