reflection about blogging using blogs for education or learning



      The advancement of technologies creates new opportunities for learning and teaching. Here, web logs (blogs) were used to promote tutor-student and student-student communication on an undergraduate course on computer applications. Results from a questionnaire survey show that students consider the act of writing a journal helped them to consolidate class instruction. Blogs served well as a tool for communication with the tutor, and there were frequent peer-peer communications. However, analysis of patterns of interaction showed that blogs were not well used as a communication tool for interactions with student peers. Students were also uncomfortable expressing their feelings, or their opinions about the course, in such a public forum as a blog. Better strategies  are needed to encourage students to engage in a collaborative culture. 
       A blog is a publication mechanism, like a journal or bulletin. Blogs can promote open dialogue and encourage community building in which both the bloggers and commenter exchange opinions, ideas, and attitudes. Teachers can use a blog to publish instructional materials that the students can access to and where the students can make comments. Teachers can also let students set up their own blogs for a particular subject or for several subjects and then assign tasks to students. The tasks should be done using blogs . While the students develop their own blogs, teachers can observe and monitor the students' progress, and identify the learning needs that have not been considered. As the information on students' blogs are growing, teachers need to classify, summarize and evaluate different students' blogs and then publish the teachers' opinions, directions, and feedback on their own blogs or on class blogs. By doing this, teachers are actually putting students to the right tracks, because if you just let students publish what ever they like, the use of blog could be out of control, and the relevance between the blog and the content being taught and learning will be reduced.
         In education communication is a vital skill. Communication is key with the students but with the parents as well. Through creating a blog for yourself and your students you open a new way for your students to communicate with other students. It creates a social interaction between you and your students which helps the students to become comfortable in their learning environment, leading to student success. Studies show that students perform better when they are being student taught. When students use blogs for their writing assignments other students are their audience, this helps students create better writing skills and encourages students to collaborate about these topics. You as the teacher can post websites that are beneficial to their learning or even post games for them to practice certain skills. If a student or parent has a question about the homework they can post it. I you do not respond right away, another parent or another student may be able to answer it for them. It is a great way to communicate with parents and keep them involved in what is going on in the classroom with their child, even if they cannot physically be there.  Blogs are search engine friendly and they are easy to maintain.

content about shape

Shape
A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture, material composition.
Psychologists have theorized that humans mentally break down images into simple geometric shapes called geons. Examples of geons include cones and spheres.

Classification of simple shapes
Main article: Lists of shapes
A variety of polygonal shapes.
Some simple shapes can be put into broad categories. For instance, polygons are classified according to their number of edges as triangles, quadrilaterals, pentagons, etc. Each of these is divided into smaller categories; triangles can be equilateral, isosceles, obtuse, acute, scalene, etc. while quadrilaterals can be rectangles, rhombi, trapezoids, squares, etc.
Other common shapes are points, lines, planes, and conic sections such as ellipses, circles, and parabolas.
Among the most common 3-dimensional shapes are polyhedra, which are shapes with flat faces; ellipsoids, which are egg-shaped or sphere-shaped objects; cylinders; and cones.
If an object falls into one of these categories exactly or even approximately, we can use it to describe the shape of the object. Thus, we say that the shape of a manhole cover is a circle, because it is approximately the same geometric object as an actual geometric circle.

         At the end of the lesson, the pupils will be able to:
    1. Recognize and name each shape with 100 percent accuracy.
    2. Draw each shape to the best of their ability.
    3. Name at least one defining characteristic of each shape

II. Subject Matter: 
         Topic: 5 Basic Shapes
         Reference: http://teachers.net/lessons/posts/1361.html
        Materials:
               *Each child will receive these shapes made out of colored construction paper:
                    - 1 yellow circle
                    - 1 blue square
                    - 1 red triangle
                    - 1 green rectangle
                    - 1 purple star
               *1 box of round Ritz crackers
               *1 box of square Saltines
               *1 bag of Tostitos Nacho Chops
               *1 bag of Chocolate Wafer Cookies
               *1 bag of star shaped marshmallows
               *1 large yellow circle made out of colored construction paper
               *1 large blue square made out of colored construction paper
               *1 large red triangle made out of colored construction paper
               *1 large green rectangle made out of colored construction paper
               *1 large purple star made out of colored construction paper

III. Procedure:
A.    Preparatory Activities:
a.       Prayer
b.      Greetings
c.       Checking of Attendance
d.      Motivation
Sing a song entitled: 
                                                  “They are Shapes”
                                                Square and Circle2x
                                                       Triangle2x
                                             Rectangle and Oblong2x
                                                They are shapes2x


B.     Lesson Proper:
·         First, I will ask the students if they know any names of shapes. I will also inquire about where they see different shapes around their homes or outside. I will also give examples of my own. (Examples: lights on a traffic light, television sets, buildings, etc.) 5 minutes
·         I will then say to the class the following: "Today we will be learning about 5 basic shapes- circles, squares, triangles, rectangles, and stars. We see these different shapes everyday, and it is very important for us to recognize these shapes. We will be counting the sides and corners of each shape. By doing this, we will be able to identify the shape name." 3 minutes
·         "First, we will learn about circles. Circles are round. Circles do not have straight edges or corners. (I will then hang the large yellow circle on the chalkboard)
            -Can anyone give me an example of a circle object in your house?
 Next we will learn about squares. There are many squares in our everyday life. Squares have four straight sides that are all the same length, or size. (I will put up the blue square on the chalkboard. Pointing to the shape, I will explain:) Two sides meet to form corners. There are four corners in every square.
What about in our classroom?
- We are in a squared room right now. There are four corners in this room.
·         Next, we will learn about rectangles. Rectangles are almost like squares, but their sides are not all the same size. (I will put the green rectangle on the chalkboard)
      -Can anyone think of an object that has a square shape?
·         Next, we will learn about triangles.
How many corners does a triangle have?
     -Triangles have three sides. (I will hang the red triangle on the board, point to this shape, and say:)
 Can anyone think of some triangles we see in everyday life?
     -Two sides of a triangle come together to form corners also.
·         Finally we will learn about stars. (I will put the purple star on theboard) Stars are made up of small triangles. A star has five corners, and 10 sides. I will then pass out one of each kind of food shape to each child to show the differences between the 5 basic shapes. (20 minutes)
C.     Activities
                    A short and simple ditto will be handed out to the students. Each student will
                    individually finish and show the teacher the ditto when completed. 15 minutes
D.    Generalization
·          When I finish my short discussion on shapes, I will then ask the class if they have any questions. I will answer and explain any questions or confusion, and then do a short activity with the class. Each child should have been given three small, laminated shapes of a yellow circle, blue square, red triangle, green rectangle, and purple star made of colored construction paper. I will then say the following: "Class, I am going to ask you questions about the shapeswe learned about today. When you know what shape I am describing, please hold your shape up high in the air.
Ask the following questions:
                         - Which shape has three corners?
                         - Which shape is round?
                         - Which shape has four sides that are all the same?
                         - Which shape is made of small triangles?
                         - Which shape has no straight edges?
                         - Which shape has five corners?
                         - Which shape has four sides that look different?
                         - Which shape has three sides and three corners?
                The students may then eat their "shapes" that they were given previously. (7 minutes)
·         Finally, I will review the shapes one last time by holding up the larger shapes to the entire class and have them answer as a group what shape it is that I am holding up for them to see. (10 minutes)
IV. Evaluation:
·          Each learner will return a completed work sheet with the drawings of their shapes.

Worksheet
