Not So Neutral Views
Students are introduced to acids and bases, and the environmental problem of acid rain. They explore ways to use indicators to distinguish between acids and bases. Students also conduct a simple experiment to model and discuss the harmful effects of acid rain on our living and non-living environment, as well as how engineers address acid rain. In an associated literacy activity, students learn how persuasive techniques are used to develop an argument, and create an environmental case study.
Supporting Teachers Intervention in Collaborative Knowledge Building
In the context of distributed collaborative learning, the teacher's role is different from traditional teacher-centered environments, they are coordinators/facilitators, guides, and co-learners. They monitor the collaboration activities within a group, detect problems and intervene in the collaboration to give advice and learn alongside students at the same time. We have designed an Assistant to support teachers intervention in collaborative knowledge building. The Assistant monitors the collabo
Evaluating How Our Students Think and Learn: Research Results from the Trenches
This PowerPoint presentation addresses research on the thinking and learning processes of students and how increased knowledge of these processes can be used to structure lectures in a manner that will change the way students learn. It covers methods for course redesign, classroom assessment techniques, levels of learning and goals in general education courses. Among other things, it was found that student success is predictable, all students benefit from active learning, and group work is impor
Developing Questions for Gallery Walk to Engage Higher Order Thinking
This site from SERC's Starting Point explains best practices for developing Gallery Walk questions which involves preparing questions based on a lecture's central concept, issue, or debate. A variety of questions can be used but the technique seems to work best with higher order questions relating to analysis, evaluation, and synthesis; using Bloom's Hierarchy provides a guide for wording questions at various levels of abstraction. Examples of various types of questions including comprehension,
Contour Basics is an exercise designed to introduce students to contour plots. The Contour Activity is a great on-line resource that starts slowly and increases in difficulty. It teaches students basic techniques for generating contours, introduces students to the subtleties of generating contour plots with sparse data, provides many opportunities for students to assess their own progress and understanding and has complete on-line drawing capabilities. The exercise is geared toward atmospheric a
Conservation Ecology: Lessons from the physics education reform effort
Starting in 1992, introductory physics students at Indiana University were pre- and post-tested on their knowledge of general physics. Some students received standard classes of lectures and tests, while others were taught using interactive engagement (IE) techniques. The goal of the study was this: can IE methods increase the effectiveness of introductory mechanics courses? Though the study focused on physics and mechanics specifically, the techniques used can be applied in teaching other scien
This site from SERC's Starting Point explains that active learning is a student centered approach in which the responsibility for learning is placed upon the student, often working in collaboration with classmates. Links to examples of Active Learning techniques are included on the site.
Cannonball Adderley and the Cannonball Express. Program contains numerous 'magazine-style' segments, of which the most prominent is host John Slade's interview with musician Cannonball Adderley. Accompanying the interview, in segments before and after, is performance footage of Adderley's jazz band Cannonball Express (with Bobby Timmons, Walter Booker and Roy McCurdy) shot live at Paul's Mall in Boston the night before the interview. Other segments include a performance by the Immala Blakely Dan
As if Memories Could Deceive Me
'As if Memories Could Deceive Me,' 1986, documents a performance or rehearsal of the New England Conservatory Symphony Orchestra, through close-ups, split-screen effects, and collage techniques. Instruments are filmed close-up and appear in boxed-off portions of the screen. As the music rises, archival film images begin to creep in. Many times they are superimposed over the instruments. Film footage includes the interior of a colorful palace, Hitler propaganda and Nuremberg trials, and a men's c
Anges Rebelles, Les
"In six minutes, a conjuring trick combining special effects and the magic of painting enables us to enter the world of Jacques Brissot. It is a visual poem that humorously recounts the building of a collage inspired from artist Peter Breugel's 'La Chute des Anges Rebelles.'" Artist Jacques Brissot is shown adding to and retouching a large-scale collage work, lending insight into his compositional choices and his techniques and methods. Music is by Michel Arich, with Barney Wilen playing saxopho
What Is Service Learning?
Learning in the context of real-world problems through activities that not only promote student learning but also serve the public. Environmental and analytical chemistry courses provide a background for using scientific skills to work with the community and gain an understanding of a scientist's role in society. A group of faculty was convened to examine how service learning can best fit into chemistry instructional programs.
SGE Chromatography Products - Troubleshooting and Training
A guide to troubleshooting chromatography problems, especially GC. There is also material on increasing column efficiency and reference material on properties of stationary phases.
Chemistry-Based QuickTime, Shockwave Flash, GIF Animations, and Streaming Audio
The Chemistry-Based QuickTime, Shockwave Flash, GIF Animations, and Streaming Audio Web site is provided to "support the teaching of concepts in chemistry in freshman through graduate level courses." Dr. Thomas Chasteen's site offers links to multimedia files related to chemiluminescence, gel electrophoresis, how a grating works, gas chromatography and mass spectrometry, titrations, atomic emission detector, and much more. The site is a good collection of helpful visual learning tools that chemi
The NIST Webbook
Chemical and physical property data on over 30,000 compounds. Information includes mass spectra, infrared spectra, UV-Vis spectra, and a large amount of thermodynamic data generated by NIST scientists over the last 30 years.
Tournaments : I've got to win how many games?
In this activity, students are challenged to determine how many more basketball games were played in a tournament with a field of 64 teams, compared to a field of 32 teams. Part of the Figure This! collection of 80 math challenges, this exploration challenges students to use a variety of problem-solving techniques that include developing equations, making tables, and drawing tournament brackets. The importance of these strategies in making business decisions and planning space missions is noted.
How to accelerate your Internet
Access to sufficient Internet bandwidth enables worldwide electronic collaboration, access to informational resources, rapid and effective communication, and grants membership to a global community. Therefore, bandwidth is probably the single most critical resource at the disposal of a modern organisation. The goal of this book is to provide practical information on how to gain the largest possible benefit from your connection to the Internet. By applying the monitoring and optimisation techniqu
Hodges Health Career - Care Domains - Model
Hodges’ Health Career (Care Domains) Model provides a conceptual framework upon which users can map problems, issues and solutions across four knowledge domains: Interpersonal; Sociological; Scientific; & Political (Autonomy). The public may also be taught to use the model, enabling engagement, understanding and concordance in planning and outcome evaluation. Brian Hodges' original notes, a resources page and links (800+) are included. Additional material on health informatics and the potenti

How to Improve Critical Thinking Using Educational Technology
Critical thinking is one of education's central goals and most valued outcomes, but it can difficult to teach effectively. The Reason! project has developed the Reason!Able software as part of a general method aimed at enhancing critical thinking skills. This paper describes the challenges involved, the theoretical basis of the Reason! project, the Reason!Able software, and results of intensive evaluation of the Reason! approach.
