Play and Learn....

"Presented article talks about Game Based Teaching Model (GBTM) that applies inquiry as a strategy to teach and learn, connect classroom teaching with real life experiences and prove as a useful demonstration tool for instructions in physics classrooms. It advocates motivating children to learn through their surrounding games. This methodology may serve to teach physics principles to middle and high school students using play as the basic component of the approach. It also develops skills of pre-knowledge, logical reasoning, concentration and nurture inquisition based scientific temperament in learner. It further develops strategy making and problem solving (monitoring) among the students. This model displays how to overcome traditional teaching methods (pure lecturing and chalk-talk), how to draw student’s attention in the class and how to convert initial ‘thrust’ into ‘ample engagement’ strengthening active learning"

What is ET (Educational Technology) and what it can do for us?

We got the opportunity to brainstorm on what ET (Educational Technology) is and what exactly it can do for us. Educational Technology automates all structured learning Processes, making them productive and efficient. Hence, teachers can use available instructional resources for higher order learning, which creates value and meaning for learners (NU, ET definition). It allows to have transformation of content based teaching practices to processes based teaching practices.

It focuses mainly on pedagogy not only on technology tools. It cater to different types of learner in the same classroom and enable teacher to understand  how learners’ brains work to engage them for purposeful learning. Through this we learn to develop instructional designs using different learning themes. ET blends variety of learning strategies and develops an environment for collaborative learning by including the components of experiential learning. The foremost (and long-lasting) benefit of ET is it keeps you abreast with the changing world.

  

I am thankful to Harleen (YPS, Mohali), Vasumathi (Miyo Girls School, Ajmer and Apu, Miyo Boys School, Ajmer) for their inputs during discussion and enthusiastic involvement in all the activities we got to do throughout the stay.

I acknowledge, on behalf of all of us, the guidance and support of our mentors Prof. Mandke and Dr. Shradha Kanwar.

Talk of Prof. Karmeshu on 'Diffusion of ICT and Critical Mass'

Date: June 06’ 2014 (Friday)

Venue: ETIC, NU

Resource Person: Prof. Karmeshu (School of computer and system sciences, JNU, Delhi)

Following were present:

Prof. Vijay Mandke

Ms. Deepti

Ms. Vasu

Ms. Harleen

Ms. Juhi

Mr. Jatinder

Mr. Tarun

Mr. Apu

Suresh Joshi

Focus areas of the presentation were perspectives on learning, how to learn and what are the connections of physics (and other subjects too) with the current learning practices. Prof. Karmeshu talks about the probability, ICT diffusion, SCI and SSCI journals and why personalized learning is not taking a boom. He emphasized that it is due to lack of teacher training in our education system. ICT which is identified as convergence of information processing and communication system has been discussed and ICT diffusion phases have also been discussed which are as follows:

1.     Knowledge phase

2.     Persuation phase

3.     Decision phase

4.     Implementation

5.     confirmation

(Reference – ICT knowledge for ICT diffusion: Rogers)

Innovation diffusion processes have been discussed along with the adoption through communication channels, mass media and inter-personal communication (word of mouth) and finally we came to know that how to promote innovative thinking. Rigorous discussion took place when Prof Mandke talks about on how the principles of practices of learning engineering can be brought into the teaching practices to make them brain aligned. It is explored through the brainstorming discussion was the information processing rate and flow of information are the vital components of knowledge progression.

        In a nut shell, the talk was highly informative and all ET scholars were able to interact with the resource person individually. We thank to Prof. Karmeshu for delivering the fruitful lecture and Prof. Mandke and Dr. Shradha Kanwar for having organized such a great learning event for us.

    

Value stream presentation at NU....finally..

Date: June 04' 14

Venue: Education Technology Innovation Center, NU

Today we were very excited to present our value streams that we have been working on from last four months. Value stream documents were presented in the form of research and development project papers (I, II and III) by all the students of M. Tech. (ET) program in the university. Presentations have been evaluated by Prof. Vijay V Mandke, Mentor Professor of ET area and Dr. Shradha Kanwar, Associate Professor and area director of ET in the university. Three presentations are over (Vasumathi, Suresh and Jatinder), three are left (Tarun, Juhi and Harleen) and Appu Dey was presenting at the time of writing the post.

It has been actually a value creating, strategizing, developing and implementing what we have learnt as ET scholars at NU.

Here comes rest of the presentations of Appu, Juhi, Tarun and Harleen.

 

All of us are highly thankful to our mentors Prof. Mandke and Dr. Shradha for their guidance while developing these research documents and, more prominently, during the program.

 I gratefully acknowledge the guidance and support of my Principal Mr. Ashok K Pandey, mentorship of Prof. Mandke and Dr. Shradha and cooperation of my fellow ET scholars during the program. Financial support of Ahlcon International School and NIIT university in pursuing the course is greatly acknowledged.

     

NBL activity...Real time learning....

NBL Activity

May 29' 2014 (Thursday)

 

Just now we have been briefed on what we have to do and my two teammates are busy in selecting the questions from the chapters 9 to 17. Dr. Shradha (our mentor at NU) is elaborating on each and every point here as we were not able to hear Uday's (our instructor for NBL) voice clearly on phone.

Here is group group pic.

Glimpses of last visit to NIIT University (December' 13 - January' 14)......Looking forward to have this visit even better..

These are the glimpses of our last NIIT University stay which was held in the end December 2013 to the beginning of January 2014. We had a nice learning experience throughout the stay and look forward to have even better experience this time (28 May - 8 June 2014). 
Let us remember last NU stay ....... and make this stay more fruitful......Amen....

 

 

 

Workshop for High - School Teachers from Bal Bharti Public Schools Across the Country

This post contains pictures and the glimpses of the presentation during the workshop conducted by me for science teachers of Bal Bharati Public Schools from all across the Country at BBPS Training Centre, Pitampura on May 19' 2014. 

The workshop was the part of In-Service Training Programme of Bla Bharti high -  school science teachers on the topic 'Use of ICT in science teaching' and it was a great success as the teachers liked the content and the tech - tool (Popplet) they have learnt. 

The experience was highly enriching for me as a learner. I would like to thank my Principal Mr. Ashok K Pandey for providing me the opportunity and Prof. H. O. Gupta, (Retd. from NCERT) and S. K. Bhattacharya, Chairman for their facilitation and hosting.
