While a much larger percentage of American families are located in the top income bracket in 1990 compared to fifty years ago, there were still slightly over 1/4 of American families with income of $25K or less in 1990.
In this lesson, students learn that navigational techniques change when people travel to different places land, sea, air and in space. For example, an explorer traveling by land uses different methods of navigation than a sailor or an astronaut.
Introduces students to the basic tools in using data to make informed management decisions. Covers introductory probability, decision analysis, basic statistics, regression, simulation, and linear and nonlinear optimization. Computer spreadsheet exercises and examples drawn from marketing, finance, operations management, and other management functions. Restricted to Sloan Fellows.
There is no question that life in America has changed drastically in the past fifty years. Given the importance of examining historical change inherent in the life course perspective, it is important to determine how changes in the social structure over time impact individuals. Therefore, the goals of this data analysis exercise are to examine changes in marriage and employment over the last fifty years. The purposes are to identify the changes that have taken place, and to hypothesize how these changes may affect the process of desistance from crime today.
The challenge of this activity is to determine the number of times the student needs to cut the strip of paper in half in order to make it between zero and ten nanometers long.
Students need many experiences tossing one die, collecting data and analyzing that data to construct meaning for the probability of the different outcomes. Since a small student sample is often skewed, it is necessary for teachers to help students collate class data to better approximate the theoretical probability that the outcomes of tossing a single die are equally likely. The one-die games below motivate data collection opportunities that students will play again and again while generating larger data samples for class discussion. Many teachers find a simple class tally chart an effective way to organize data for this ongoing experiment. Students simply add results to the class results as they complete a game. Class discussions focus on the fairness of the games and discussion about whether each player has an equal chance of winning.
Diagrams, charts and graphs are used by all sorts of people to express information in a visual way, whether it's in a report by a colleague or a plan from your interior designer. This unit will teach you how to interpret these tools and how to use them yo
Focusing on education, we will examine the changes from 1950 to 1990 in the numbers, race, gender, and occupations of high school and college graduates. Turning our attention to cohorts and population structure, we will trace birth trends over the past four decades, namely the Baby Boom, and discuss possible causes and effects.
The power of graphics should not the underestimated. They can express information clearly and simply. This unit will help you to assess which style of graphic to use in different situations.
Diagrams, mind-maps, tables, graphs, time lines, flow charts, sequence diagrams, decision trees: all can be used to organise thought. This unit will introduce you to a variety of thinking skills. Asking and answering questions is at the heart of high-quality thinking. Questions naturally arise from the desire to know and learn about things and may be the starting point for a journey of understanding.
In this video segment from Garden Insects, learn about six varieties of spiders that live in one garden.
Your course might not include any maths or technical content but, at some point during your studies, it's likely that you'll come across information represented in charts, graphs and tables. You'll be expected to know how to interpret this information, and possibly encouraged to present your own findings in this way. This unit will help you to develop the skills you need to do this, and gain the confidence to use them. This unit can be used in conjunction with, and builds on the 'Working with charts, graphs and tables' unit.
In this activity, students explore the importance of charts to navigation on bodies of water. Using one worksheet, students learn to read the major map features found on a real nautical chart. Using another worksheet, students draw their own nautical chart using the symbols and identifying information learned.
Tables and charts are a great way to present numerical information in a clear and concise form. This unit explains how to use the Windows calculator to carry out basic operations and calculate percentages. You will then learn how to use charts and tables to represent and interpret information.
This activity provides a look at race and ethnicity inequality in the United States over time.
Place and Location are two of the five themes of geography and a natural starting point for a study of the Arctic and Antarctica. Location answers the question, "Where am I?" while the study of place asks, "What kind of a place is it?" and, "How does this place connect to my hometown?" This issue of Beyond Penguins and Polar Bears examines how you can introduce the Arctic and Antarctica and use science, geography, literacy, and technology to help your students compare and contrast these two dramatically different areas as well as their own home. Get ready for an adventure as you and your students develop your polar sense of place!
Beyond Penguins and Polar Bears is an online professional development magazine for elementary teachers which focuses on preparing teachers to teach polar science concepts in an already congested curriculum by integrating inquiry-based science with literacy teaching. Such an integrated approach can increase students' science knowledge, academic language, reading comprehension, and written and oral discourse abilities.
Your course might not include any maths or technical content but, at some point during your course, it’s likely that you’ll come across information represented in charts, graphs and tables. You’ll be expected to know how to interpret this information. This unit will help you to develop the skills you need to do this. This unit can be used in conjunction with the ‘More working with charts, graphs and tables’ unit, which looks into more ways to present statistical information and shows you how to use charts, graphs and tables to present your own information.
