Tablet PC andTeaching Mathematics by Dr. F Ma and F Saddigh 3PM–4PM Sept. 26 2012 NEA 229 LA Harbor College Introduction to Tablets PC There are three types of tablets iPads, Androids, and Window tablet PC’s. Of the three systems, the Window 7 tablet PC’s have by far the most robust pen driven system. http://en.wikipedia.org/wiki/Microsoft_Tablet_PC http://tablet-pc-review.toptenreviews.com/ Narrative Databases and a Tablet–Instructional Platform Narrative databases are databases where the content is designed to be revealed in discrete incremental steps that are appropriate to the level of the audience. Narrative databases digitally reproduce the traditional classroom instruction that the students are familiar with. A narrative tablet–instructional platform (NTIP) is a teaching system where the instructor utilizes a pen based* tablet in conjunction with narrative databases as the main teaching tool. The narrative example given below is constructed with Microsoft Power Point (PPT) though any similar authoring software may be used for its construction. Components of the NTIP The components needed for the NTIP are listed below.

A new line is introduced only when the instructor is certain that most of the class understands the current line. The instructor may comment, annotate or provide clarification about the presentation directly on the tablet, (see the attachment for example of the line–by–line databases), the instructor can access and incorporate any software or online information, all at the tip of a digital pen. The students have textbooks which contain a condensed form of the database. Because the textbook already contains the printed version of the databases, it reduces the task of note– taking and offers students a better chance to concentrate and comprehend the lectures in class. The students may access the line-by-line narrative databases on the internet. This combination of the databases, tablet presentations, the textbook, and internet access to the database constitute the NTIP. Advantages of the NTIP Some of the advantages of the NTIP are given here. * The NTIP helps learners in synthesizing the knowledge. Demo: 1. Volume of the Intersection of Two Pipes2. The Monty Hall Problem * Once the database is constructed, it is easy to edit and polish as instructors gain experience in the classroom. In other words, the database gets better as time goes on. * The instructor can instantly access all necessary software or internet resources with the tablet, allowing them to organize all curriculum material in one place via the tablet. Some of the advantages of the NTIP for students are given here. * The lessons are presented in discrete increments in accordance to their structure and the background of the students in the same manner the instructor presents the lectures in class. * The narrative format is easier than the traditional print format for one to pick up where one left off in the curricula.

The instructor will not be confined to the blackboard area and can act as a tutor and as a presenter simultaneously. * The tablet enhances communications in the classroom such as sharing student’s works * NTIP is particularly helpful for instructors who have difficulty writing on the boards or who is allergic to chalk dust and chemical. * The tablet offers an incentive to instructors to take technology into the classroom hence introduce the technology to the students *The Pen Input Keyboard, voice, touch, and the pen are common forms of input methods. The following are two examples of research in these areas involving pen–input systems. A touch + pen input MS grip–sensitive multipurpose pen. The digital–pen dexterity is an important skill modern age. It’sam indispensable tool for students in STEM, or any graphic interface in art or design. We need offer the opportunity for the students to learn these skills. This will only happen through the instructors.

- 4. Technology in Classes Ihave made up few Calculus III and Linear Algebra problems to demonstrate how Microsoft Mathematics can be used. With this program you can graph in 2-D ,3-D, and polar coordintes.Also you can differentiate, integrate and reduce matrices to row echelon form. These are just a few examples of many functions it can perform. 1) Graph the following (the extreme value(s) and saddle point). a) b) 2) Graph the polar equation: r = 1 - . 3) Graph and find points of intersection between r=1 and r =1- 4) Find the volume of the wedge –shaped solid that lies above the xy-plane, below the plane z = x, and within the cylinder + . Solution: The base is semicircle of radius 2, but the by symmetry we may integrate the 1st quadrant and double the result. V= = 5) Verify that the integral is equal to . 6) Find the volume of the region D enclosed by the surfaces and . Graph 7)) If A = a) reduce to row echelon b) Find inverse of A.
