I have learned about pi:

1. What is Pi?

I knew that, pi is the ratio of the circumference of a circle to its diameter. Pi is always the same number, no matter which circle you use to compute it.

2. How do we calculate the value of pi?

I knew that, how to calculate the value of Pi: Pi is the ratio of a circle's circumference to its diameter, such that Pi = c/d, where c is the circumference and d is the diameter. There are many methods for calculating Pi; some of them have been known since antiquity, while others have been discovered relatively recently.



Calculate Pi with the method used by Archimedes.



Use the method discovered by Madhava of Sangamagrama in the 15th century.



Examine the solution for Pi found by Leonhard Euler in 1735.



The formula Pi = 176 tan^--1(1/57) + 28 tan^--1(239) - 48tan^--1(682) + 96 tan^--1(12943) ... was used in 2002 to calculate Pi to 1,241,100,000,000 digits.
Pi = 22/7 or Pi=3.14

3. What is the history behind Pi?

I knew that, the history of Pi : Pi has been known for almost 4000 years, The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for pi, which is a closer approximation.
In the Egyptian Rhind Papyrus (ca.1650 BC), there is evidence that the Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for pi.

4. Why is Pi an important value in every day life?

I knew that, why is Pi an important value in our life: Pi is important especially in anything such as graphing or construction because it is needed to make a circle every day. Pi is perhaps the most important mathematical constant. It appears in various formulas throughout math and science in fields as diverse as physics, statistics, and sociology.

Day 1

Task 1


1.1 What are your expectations of RBO?

May be to learn about web based learning and mobile learning and to learn how to create blog.

1.2 What is Web based and Mobile Learning?
Web-Based: a web application is an application that is accessed via web browser over a network such as the Internet or an intranet.

http://en.wikipedia.org/wiki/Web_based

I think that web based is information made available via the World Wide Web.

Mobile learning (m-learning): refers to the use of mobile and handheld IT devices, such as Personal Digital Assistants (PDAs), mobile telephones, laptops and tablet PC technologies, in teaching and learning


http://www.excellencegateway.org.uk/page.aspx?o=ferl.aclearn.page.id958

I think that mobile learning: using mobile in learning and teaching. It enhances learning by communication, information sharing, interoperability, and collaboration via mobile.

1.3 How are you going to give the information to me?
May be by sending it to your email or via blog.

Theories of learning

Day 1

 

Task 2

2.1 What is learning?

Learning is often defined as a change in behavior (Birkenholz, 1999), which is demonstrated by people implementing knowledge, skills, or practices derived from education. As an end result, we know that learning occurs when people take newfound information and incorporate it into their life.

www.umsl.edu/technology/frc/DEID/destination2adultlearning/learning.pdf

 

I think that: Learning is a permanent change in behaviors brought about by experience.

 

2.2 Theories of learning:

* Behaviorism as a theory was most developed by B. F. Skinner. In essence, three basic assumptions are held to be true. First, learning is manifested by a change in behavior. Second, the environment shapes behavior. And third, the principles of contiguity and reinforcement.
This theory defines learning, which is the acquisition of new behavior through conditioning.

http://en.wikipedia.org/wiki/Learning_theory_(education)#Behaviorism

 

*Constructivism
is a theory of learning based on the idea that knowledge is constructed by the knower based on mental activity. Also Constructivism is a philosophy of learning founded on the premise that, by reflecting on our experiences. This theory defines learning, which is simply the process of adjusting our mental models to accommodate new experiences.

http://www.usask.ca/education/coursework/802papers/Skaalid/definition.html

http://www.funderstanding.com/content/constructivism

 

* "Cognitive theorists recognize that much learning involves associations established through contiguity and repetition.

http://port.inst.uhcl.edu/LarsenM/INST5131PhilosophyInstructdesign.doc.

 

* Brain-based learning this learning theory is based on the structure and function of the brain.

http://www.funderstanding.com/content/brain-based-learning

 

2.3 Bloom's Taxonomy

Benjamin Bloom developed, in the 1956 while working at the University of Chicago, developed his theory on Educational Objectives. He proposed 3 domains or areas:

• Cognitive - person's ability to process and utilize information (thinking), this is what Bloom's Taxonomy is based on
  
• Affective - This is the role of feeling and attitudes in the learning/education process
  
• Psychomotor - This is manipulative or physical skills
  

Bloom's Taxonomy is taxonomy of activities and behaviors' that exemplify higher order thinking skills (HOTS) and lower order thinking skills (LOTS). Bloom's allows use to rank and structure different classroom activities and plan the learning process. In the 2001, Lorin Anderson and other revised Bloom's original work to give use Bloom's Revised Taxonomy.

 

Bloom's Original taxonomy	Bloom's revised taxonomy
Evaluation	Creating
Synthesis	Evaluating
Analysis	Analyzing
Application	Applying
Comprehension	Understanding
Knowledge	Remembering

Lesson (second degree equations)

Day 1

Task 3

3.1 What materials you use?
I started the lesson (Solve the second degree equation in one variable) by using computer and software program and I used the projector to present information.

3.2 What are the learning activities?
If I used learning style is visual, I make the students, draw pictures in the margins, look at the graphics, and read the text that explains the graphics, envision the topic in their thoughts.

If I used learning style is auditory, I make the students, listen to the words when I read and I used audio narration to attract the student learning, try to develop an internal conversation between their and the text.

If I used learning style is tactile/kinesthetic, I used a pencil or highlighter pen to mark passages that are meaningful to them, I make the students to take notes, transferring the information to the margins of the book, or onto a computer. I hold the book in my hands instead of placing it on a table. I walk around when I am reading.

3.3 What are the teaching activities?
I putted the main objectives for my lesson before I start, the students must be able to:


The student will be introduced to various methods of solving quadratic equations.



Find square roots of variable expressions and use them to solve equations and problems.



Choose the best method for solving a quadratic equation

I asked the students about the previous knowledge, which related to this lesson and I asked them to draw concept map (about Methods, which using to solve the second degree equation) such as analyses by completing square, I gave them real examples to fix new information (solve the second degree equation by using new rule).



Also I gave them many examples about how to apply this rule and I followed them when they work to help them.

3.4 How do you assess?
I gave them a simple quiz about 15 minute to assess the students if they understand or not.

RBO examination

 

1. What are a Web Quest and Web2.0 tools?

 

Web Quest:

A Web Quest is an inquiry-oriented activity in which some or all of the information that learners interact with comes from resources on the internet, optionally supplemented with videoconferencing.

Bernie Dodge San Diego State University

http://webquest.sdsu.edu/about_webquests.html

 

I think that web quest is learning activity and it used by learners and teachers.

 

Web2.0:

 

Web 2.0 refers to a perceived second generation of web development and design that facilitates communication, secure information sharing, interoperability, and collaboration on the World Wide Web.

http://en.wikipedia.org/wiki/Web_2.0#Definition

I think that a web 2.0 means is a way to put information and pull information from a variety of sites to achieve new purposes.
