"A German Beer Garden on Sunday Evening."
Between 1820 and 1860, 1,500,000 immigrants arrived in America from Germany. Many of the new arrivals who settled in cities such as New York worked as shopkeepers and skilled tradesmen, although many more worked as employees in construction, brewing, and manufacturing. Although German immigrants did not mix politics and liquor, reformers were disconcerted by the atmosphere of their social establishments. Unlike the bars in Irish neighborhoods, the beer gardens catered to whole families. As this

Beyond logging of fingertip actions: analysis of collaborative learning using multiple sources of da
In this article we discuss key requirements for collecting behavioural data concerning technology-supported collaborative learning activities. It is argued that the common practice of analysis of computer generated logfiles of user interactions with software tools is not enough for building a thorough view of the activity. Instead more contextual information is needed to be captured in multiple media like video, audio files, snapshots, etc, in order to re-construct the learning process. A softwa

"A Damaging Impression of Hollywood Has Spread": Movie "Czar" Eric Johnston Testifies before HUAC
The House Committee on Un-American Activities (HUAC) held hearings in October 1947 on Communist activity in Hollywood. In the following testimony, Eric Johnston, a successful businessman who in 1945 succeeded Will H. Hays as President of the Motion Picture Association of America--the industry's institution for self-regulation--defended Hollywood against HUAC's attacks and complained vigorously that the "atmosphere of fear" resulting from the investigation precluded the production of "good and ho

Weather Watchers
Students are introduced to some essential meteorology concepts so they more fully understand the impact of meteorological activity on air pollution control and prevention. First, they develop an understanding of the magnitude and importance of air pressure. Next, they build a simple aneroid barometer to understand how air pressure information is related to weather prediction. Then, students explore the concept of relative humidity and its connection to weather prediction. Finally, students learn

Fostering computer supported collaborative learning with cooperation scripts and scaffolds
The study investigates collaborative learning of small groups via text-based computer-mediated communication. We analyzed how two approaches to pre-structure communication influence participation, individual knowledge transfer, the convergence of participation and the convergence of knowledge among peers. We varied the factor scripted cooperation and the factor scaffolding in a 2x2-design. 105 university students of Educational Psychology participated. Results show that scripted cooperation was

Introducing Copyright
A plain language guide to copyright in the 21st century By Julien Hofman Computers and the Internet have transformed the way we produce and distribute information and entertainment. And copyright is struggling to keep pace with these changes. The authors of all kinds of works, from the humble email to blockbuster films, rely on copyright to protect what they produce. But authors and those who use their work are often unclear about what copyright allows and what it prohibits. This book was wri

How to Think Like a Computer Scientist: Learning with Python
Python is a fun and extremely easy-to-use programming language that has steadily gained in popularity over the last few years. Developed over ten years ago by Guido van Rossum, Python's simple syntax and overall feel is largely derived from ABC, a teaching language that was developed in the 1980's. However, Python was also created to solve real problems and it borrows a wide variety of features from programming languages such as C++, Java, Modula-3, and Scheme. Because of this, one of Python's m
