Situating tool

Situating tool

Situating tool means using technology to help students to understand and work with information in the context of where we are and what we're doing. It involve simulations, games and virtual reality through which students can be placed in an environment where they can get " nearly direct experiences" through practice in an artificially created model of a real situation. Instead of just reading from a book, students can use virtual stuff and explore different places. Like in science class, they can pretend to cut open a virtual frog or look inside a cell. Doing things like this helps them understand hard stuff better.

For instance, one of the example of the situating tool is virtual realty. Through this system, computer can create 3-D images on display to give students the feelings that is situated in the virtual environment. But I think simulation is more suitable in our country since we don't have virtual reality system available every school.


Concept of triangle

A triangle is a simple polygon with 3 sides and 3 interior angles. It is one of the basic shapes in geometry in which the 3 vertices are joined with each other and it is denoted by the symbol △. The most commonly seen examples of triangles are the slide of pizza and cloth hangers.

Procedure
Step by step to construct rectangle in GeoGebra
  1.  First click on GeoGebra icon from desktop 

    2. Draw two points A and B using New Point Tool
    3. Draw line segment AB using the Segment Between Two Points Tool 

  4      4. Then click on the circle: centre and radius to draw two circle each on points. 











5. Click on polygon, then click on each points and intersection to create another point to create triangle(A-B-C-A).
6. Then go to edit and click on select-hide an object and delete two circle leaving only triangle.

Digital Citizenship

  Digital Citizenship Digital citizenship refers to an engaging in appropriate and responsible behaviour when using technology or internets. Digital media provide us with unique opportunities  to get involved, to speak out our opinion, thought and emotion, and to make change both online and offline. Although we live and interact in the digital world as to the offline world, we are not always as mindful of our actions when in online. We sometimes act without realizing how it will affect our reputation, safety and growth as digital citizen. For instance, with a small action like posting or gossiping about others can have big impact on others as well as ourselves in our day to day livelihood.  There is nine domain or elements of digital citizenship. First lets go through digital access. Although we live in a 21st century digital era, not everyone and everywhere has access to technology. Particularly in rural school, not all students can afford a smartphone, computers and int...

  Middle level of ICT integration Today we are oriented with PhET simulation and how to use it in teaching and learning process.  In the 21st century education and leaning, PhET simulation play powerful tools, offering hands-on learning and experiences across various subject. PhET simulation stand for physics education technology  and it is online interactive simulation that cover wide range of subject such as physics, chemistry, mathematics and lot others. these simulation allow user to manipulate variables and observe the effect in a virtual learning environment. For instance, figure 1.1 is one of the example of PhET simulation in mathematics and science.                                                                  PhET simulation serve as educational tools in classroom and self learning environment. Te...

TPACK model

  TPACK model TPACK stands for Technological Pedagogical Content Knowledge. It's a framework that helps teachers to integrate technology into their teaching in a meaningful way. There are three type of knowledge namely content knowledgeCK), pedagogical knowledge(PK) and technlogical knowledge(TK). it emphasizes that effective teaching with technology requires an understanding of the relationships between these three types of knowledge.  Class: II Duration: 45 minutes Topic: phonic sound Subject: English Teaching learning materials video link, images and textbook ICT models :  TPACK model Teaching method collaborative learning   Previous knowledge students already learned about alphabet sound, digraph and consonant and how to sound it out.  Lesson objectives By the end of the lesson, students should be able to ; Identify which is the consonant and vowel digraph after the teacher demonstration. Write at least 5 examples for the sound without the help of the teach...
