For this project, students read Goetze and Lewis (1994) paper on trace element geochemistry of quartz-rich sandstones. They then select one of six possible stratigraphic units, find relevant literature related to their unit, and formulate sampling strategies. In class they are provided microprobe geochemical and cathodoluminescence data and manipulate/interpret it in order to reach conclusions. They answer questions regarding both the provenance of clasts from a young conglomerate as well as commenting on the validity of the data. Students learn how to manipulate and analyze data, how to make a scientific poster, and how to prepare and give an oral presentation

This e-Book is a first step toward a shift in the role of the printed textbook from authoritative serial repository to modular, customizable, linkable, interactive hub. The ideal modern textbook should provide a clear overview of the domain, short summaries of key content, links to more detailed online source material, embedded self-assessment, and a vehicle for instant student feedback. This open-source e-Book for introductory mechanics uses ideas from modeling physics to encourage strategic, concept-based problem solving and employs a wiki format to enable multiple parallel organizations of the material, links to resources and student comments.

This is a guide for Astronomy 101 instructors (and other educators) on the issues that have faced women in astronomy and the work of some of the women who can serve as role models for the next generation. Written by Andrew Fraknoi (Foothill College), it is part of a series called “Unheard Voices,” sponsored by the Heliophysics Forum of the Space Missions Directorate at NASA. The guide includes written, on-line, and audio-visual materials, many of which can be used directly in the classroom or for student papers. It features sections on: the history of women in astronomy in general, materials on selected women astronomers of the past, issues facing women in astronomy today, and materials on selected contemporary women astronomers.

This activity guides the students through a set of geological problems related to the Woodlark Basin, Papua New Guinea.

Sea surface temperature is a critical variable that determines biogeographic and distribution patterns of marine organisms. Changes in temperature influence species reproduction and survival and can affect the spread of invasive species spread and marine diseases. As a result SST is a vital indicator of changes in ecosystem health and understand patterns and causes of change are necessary for conservation decisions. . In a previous activity (Working with Scientific Data Sets in Matlab: An Exploration of Ocean Color and Sea Surface Temperature), you downloaded and sub-scened global, annually averaged SST data. In addition to understanding the year-to-year variability in SST patterns, it is important to understand the SST variability over shorter time scales e.g. daily, seasonal). In this activity we will work with a daily imagery to understand intra-annual variability of SST and interpolate values for where data has not been collected.

World History: Cultures, States, and Societies to 1500 offers a comprehensive introduction to the history of humankind from prehistory to 1500. Authored by six USG faculty members with advance degrees in History, this textbook offers up-to-date original scholarship. It covers such cultures, states, and societies as Ancient Mesopotamia, Ancient Israel, Dynastic Egypt, India’s Classical Age, the Dynasties of China, Archaic Greece, the Roman Empire, Islam, Medieval Africa, the Americas, and the Khanates of Central Asia. It includes 350 high-quality images and maps, chronologies, and learning questions to help guide student learning. Its digital nature allows students to follow links to applicable sources and videos, expanding their educational experience beyond the textbook. It provides a new and free alternative to traditional textbooks, making World History an invaluable resource in our modern age of technology and advancement.

This was originally published as an introduction to Gurevich’s first OER publication, “Critical Thinking.”(The material is curated and presented to be applicable for subjects and assignments across a number of academic disciplines.)

We present a consensus-based checklist to improve and document the transparency of research reports in social and behavioural research. An accompanying online application allows users to complete the form and generate a report that they can submit with their manuscript or post to a public repository.

Data Carpentry for Biologists is a set of teaching materials for teaching biologists how to work with data through programming, database management and computing more generally.

This repository contains the complete teaching materials (excluding exams and answers to assignments) and website for a university style and self-guided course teaching computational data skills to biologists. The course is designed to work primarily as a flipped classroom, with students reading and viewing videos before coming to class and then spending the bulk of class time working on exercises with the teacher answering questions and demoing the concepts.

The simulation shows the classic physics situation of a monkey and hunter.
In this case, the hunter is trying to tranquilize the monkey, so the monkey can be re-located to a better habitat. The monkey is clever - when the tranquilizer dart (in blue) leaves the gun, the monkey (in purple) lets go of the tree branch, and starts to fall straight down. Note that there is a net (not shown) at the bottom to catch the monkey, so the monkey won't get hurt.
How should the gun be aimed so the dart hits the monkey?

You can explore various parameters, including changing the direction the gun is aimed, changing the value of the acceleration due to gravity, and adjusting the dart's launch speed.

In this simulation, you see, on the left, a picture of a box at rest on a table. You can apply a vertical force (up or down) to the box. On the right, you can see the full free-body diagram of the box. The free-body diagram shows the gravitational force (green) exerted on the box by the Earth, the normal force (purple) exerted by the table, and the vertical force (dark blue) that you apply. Note that, on the free-body diagram, all three forces are along the vertical line passing through the center of the box, but the force of gravity and the normal force have been shifted a little so they can be seen more easily.

This study estimates the effect of data sharing on the citations of academic articles, using journal policies as a natural experiment. We begin by examining 17 high-impact journals that have adopted the requirement that data from published articles be publicly posted. We match these 17 journals to 13 journals without policy changes and find that empirical articles published just before their change in editorial policy have citation rates with no statistically significant difference from those published shortly after the shift. We then ask whether this null result stems from poor compliance with data sharing policies, and use the data sharing policy changes as instrumental variables to examine more closely two leading journals in economics and political science with relatively strong enforcement of new data policies. We find that articles that make their data available receive 97 additional citations (estimate standard error of 34). We conclude that: a) authors who share data may be rewarded eventually with additional scholarly citations, and b) data-posting policies alone do not increase the impact of articles published in a journal unless those policies are enforced.
