4434Effect of Coefficient of x on Parabola Vertex (b<0)
https://www.merlot.org/merlot/viewMaterial.htm?id=485513
This classroom activity presents College Algebra students with a ConcepTest, a Question of the Day, and a Write-pair-share activity concerning the effect of the coefficient of x on the vertex of a parabola where a>0, b<0 and a and c are arbitrarily fixed values in f(x)=ax^2+bx+c.Wed, 25 Aug 2010 11:38:16 -0700EXERCISING IN SPACE
https://www.merlot.org/merlot/viewMaterial.htm?id=906213
'Students will identify a direct variation, solve linear equations, and create tables based on the exercise equipment provided for astronauts on long duration missions on the International Space Station (ISS) in order to maintain their fitness to perform mission objectives and to return to Earth without serious health complications. Students willidentify direct variation from ordered pairs by calculating the constant of variation;calculate slope from two points using the slope formula;determine independent and dependent variables;solve linear equations; andcreate tables.'Links are provided here for both the teacher's information and the students' information.Tue, 4 Nov 2014 17:58:00 -0800Calculus of the Dinner Table: Mathematical Modeling
https://www.merlot.org/merlot/viewMaterial.htm?id=407971
Calculus students are presented with a write-pair-share activity that initially involves the construction of a model based on direct variation and later involves the use of calculus as a means by which to analyze the model. Suitable for either Calculus I or Calculus II students. Note: This project has a sequel entitled Fundamental Theorem of Calculus: An Investigation (listed under Interactive Lectures) in which the Fundamental Theorem of Calculus is investigated via the constructed model.Tue, 29 Sep 2009 10:54:50 -0700Exercises Using the 2014 General Social Survey and SPSS: Statistics
https://www.merlot.org/merlot/viewMaterial.htm?id=1066211
These exercises (16 in all) were written for instructors teaching an introductory class in statistics. They were written so each exercise is independent of the others and any one exercise can be used even if the other exercises are not used. The exercises also serve to introduce students to SPSS which is a commonly used statistical package used in many classes. A good reference on using SPSS is SPSS for Windows Version 22.0 A Basic Tutorial by Linda Fiddler, John Korey, Edward Nelson (Editor), and Elizabeth Nelson. The online version of the book is at http://ssric.org/node/459. Students are referred in the exercises to appropriate places in this book. The data set used in this exercise is gss14_subset_for_classes_STATISTICS.sav which is a subset of the 2014 General Social Survey. Each exercise consists of five files all of which can be downloaded: the exercise itself as a Word (docx) file, notes to instructor as a Word (docx) file, the data file in SPSS format, the SPSS syntax necessary to carry out the exercise as a SPSS syntax file, and the SPSS output for the exercise as a SPSS output file. You have permission to use these exercises and to revise them to fit your needs. Each exercise has a set of keywords to give you a quick view of what is covered.Tue, 22 Sep 2015 15:09:23 -0700Fundamental Theorem of Calculus: An Investigation
https://www.merlot.org/merlot/viewMaterial.htm?id=407974
Calculus students are presented with a write-pair-share activity that leads them to a practical understanding of the Fundamental Theorem of Calculus. The activity involves analyzing a function that describes eating speed in a hypothetical dinner table experience. Suitable for either Calculus I or Calculus II students.Note: This project has a prequel entitled Calculus of the Dinner Table: Mathematical Modeling (listed under Interactive Lectures) in which students construct the mathematical model for the king's eating speed. This prequel provides an excellent and engaging prelude to this activity.Tue, 29 Sep 2009 10:56:49 -0700Effect of Coefficient of x on Parabola Vertex (b>0)
