The document discusses computer-mediated collaborative learning (CMCL) in an English as a foreign language (EFL) environment. It examines CMCL through synchronous chat discussions and asynchronous wiki peer reviews compared to traditional face-to-face discussions and paper-based peer reviews. The study found that chat discussions led to more equal participation among students but fewer words per turn. Wiki peer reviews allowed for more negotiation of ideas than traditional reviews. Student interviews indicated that some felt more pressure to contribute during chat discussions, while others were less confident to share.
The document discusses the Texas STaR Chart, which is used by schools across Texas to self-assess technology integration efforts. It describes the STaR Chart as assessing four key areas: Teaching and Learning, Educator Preparation and Development, Administration and Support, and Infrastructure for Technology. Data from Seagraves ISD in 2008-2009 shows results in the developing technology range for three areas and advanced technology for Infrastructure. The STaR Chart is intended to help schools improve technology integration and ensure the best teaching and learning through monitoring annual progress.
This document discusses street lighting for primary schools and proposes solutions to lighting issues. It notes that streetlights can effectively light an area with a radius 3 times the height of the light. It then asks what would happen if lamp posts are too far apart or too close together, noting it could result in dark or too bright areas. It also asks what would happen if a lamp post is too close to a house, potentially lighting the rooms. The document proposes that a well-designed streetlight cover could help light the street without illuminating house rooms.

This document contains examples of solving related rates problems. The first example involves calculating the rate of increase of the radius of a spherical balloon as it inflates at a rate of 100 cm3/s. When the diameter is 50 cm, the radius is increasing at a rate of approximately 0.0127 cm/s. The document provides guidance on setting up related rates problems, including drawing diagrams, identifying known and unknown variables, relating variables through equations, and differentiating to solve for the unknown rate. Two additional examples involve calculating rates of change for a filling water tank and a sliding ladder.
El documento presenta una agenda sobre el calentamiento global. Cubre temas como qué es el calentamiento global, sus causas, consecuencias actuales y futuras. Explica que desde fines del siglo XIX la temperatura promedio ha aumentado entre 0.5 y 1°C debido a la contaminación y presencia de gases de efecto invernadero como el CO2. Estos gases atrapan radiación infrarroja terrestre, aumentando las temperaturas entre 1.5 y 4.5°C. El calentamiento global causará pérdidas humanas y materiales si no se to
The document provides an agenda for a Friday math class. It includes completing homework, posting to a blog, comparing population growth rates and writing equations, graphing exponential functions with different domains and determining relationships between equations and graphs within each set, and exploring the effects that changing the values of a, b, and c have on exponential graphs.

Algebra Solving Open Sentences Involving Absolute Valueguestd1dc2e
This document provides instruction on solving absolute value equations and inequalities. It begins by explaining what absolute value equations like |x|=5 mean and the two cases to consider when solving. Examples are provided of solving equations like |x+4|=5 and |x-7|=8. The document also explains how to write absolute value equations and solve inequalities, providing examples like solving |3y-3|>9 for the values of y. Key steps are outlined for both absolute value equations and inequalities.
The document discusses inverse functions. An inverse function f^-1(x) is obtained by interchanging x and y in the original function f(x). For f^-1(x) to be a function, there must be a unique y-value for each x-value. A function and its inverse are reflections across the line y=x. The domain of f(x) is the range of f^-1(x), and vice versa. To test if an inverse function exists, use the horizontal line test or check if rewriting the inverse relation as y=g(x) yields a unique expression for y. If an inverse function exists, f^-1(f(x)) = x and f(
This document lists notable rock formations from around the world, including ROCAS Árbol de Piedra in Bolivia, Brimham Rock in England, Bryce Canyon National Park in Utah, Delicate Arch in Utah, Devil's Tower in Wyoming, Goreme Valley Fairy Chimneys in Turkey, Karlu Karlu or Devil's Marbles in Australia, Landscape Arch in Utah, Montserrat in Catalunya, Palo Duro Canyon in Texas, Prekestolen (El púlpito) in Norway, Spider Rock in Arizona, The Giant's Causeway in Northern Ireland, Torcal de Antequera in Andalucía, Uluru in Australia, and Wadi Rum in
The artist takes 4 hours to paint a single hand and photographs it to preserve his work. It amazes the observer how lifelike the eyes are painted in only 10 hours to complete a two-handed eagle painting. The artist spends significant time and effort to realistically depict hands and eyes in his paintings.
The document summarizes a fable about an ant that used to work productively without supervision. However, a lion recruited more managers like a cockroach and spider to oversee the ant's work. This resulted in more paperwork and meetings for the ant, reducing her productivity. More managers and consultants were continually hired, making the department unproductive and stressful for workers like the ant. In the end, the ant was fired for having a negative attitude.
