Section 2: Design Decisions

Nature of Decisions taken

The design decisions involved in the creation of this OER were of broadly three types:

1. Content Decisions

2. Pedagogic Decisions

3. Technology Decisions

Content Decisions

The content decisions related to:

a. Earmarking specific segment to be covered – Converters{DC step down techniques}

Pedagogic Decisions

Typically in a flipped classroom strategy, there are two segments – Out-of-class segment and

In-Class segment. The out-of-class segment requires student to refer to some given material

(Video, Text etc) and form an understanding about the concepts that are relevant. In terms

of concept marking the pedagogic decisions that were taken for the Out-of-class segment

related to:

a. Cognitive Levels of Questions to be asked along with the resources – Mostly Recall

to Apply level question for out of class and Create Level question for In-class

b. Assessment Strategies – Multiple choice questions for out of class, Team-Pair-

Share strategy for in-class

Technology Decisions

While developing the Out-of-Class and In-class activities, the major technology decisions

taken were:

a. Tool to be used for creating screen cast – Screencast-O-matic, Mircosoft

powerpoint presentation, Screencast-O-matic is used to record videos by the teacher

along with powerpoint for explanation of theory.

b. Tool for sharing the OER is Wordpress & Google Drive: Wordpress has been used to

compile all the theory works & questions

c. Tool to assess the OER: Google forms. Google forms has been used for taking a survey

of the OER and a questionnaire of the same.


Section 3: OER Description

Active OER

Visit the wordpress site: https://exemplificationsite.wordpress.com/ or https://laijumit.wordpress.com/. A page has been added named: OPEN EDUCATIONAL RESOURCES: BUCK CONVERTERS

Lesson Setting

Screenshot 2: There are options for choosing the type of recording; It can be either sharing the

screen or (screen+webcam) or webcam only.

1. Choosing screen only.

2. Choosing the webcam only


3. . Choosing the webcam & screen together

Screenshot 3: Screen recorded at the end.

How to use this OER

For using this OER, please ensure that you have proper internet connectivity along with your

writing material.

Step 1: Visit the wordpress site: https://exemplificationsite.wordpress.com/

or https://laijumit.wordpress.com/.

A page has been added named: OPEN EDUCATIONAL RESOURCES: BUCK CONVERTERS.

Step 2:While accessing the page, it is the user’s choice to view the video either on the google drive’s

link or to view it through Youtube.

Step 3: Once the videos have been watched, a small questionnaire has to be attended by the

respondents for which Google forms have been used.

Step 4:Go to the link provided https://goo.gl/forms/LA04SSnT1r1gbfC82t and take the quiz by

entering your mail id.

Each question in the questionnaire carries 1 point and the test is of 10 points. At the end of the test

marks would be reflected.

Additionally, if there are some common errors made by students, you may start the face-to-

face session with a Peer Instruction question to elicit the misconception and resolve it.

Best Practices with Lesson Activity

Here are some of the best practices from our experience on using this Lesson Activity in

classroom:

1. Students to be given maximum 3 working days for completion of the activity.

2. The video can be shown in the class room & THINK-PAIR-SHARE or THINK-PAIR-

SOLO can be used in the classroom itself.

3. Once the students complete their THNIK-PAIR-SHARE activity, then make sure that

they attempt the questionnaire so that they all get the required knowledge from all

perspectives.

Section 4: Evaluating Effectiveness of OER

The OER effectiveness can be assessed at two levels:

1. At the student level

2. At the consumer level

Effectiveness at the student level

Effectiveness at the student level involves metrics related to student access of the resource

and student learning.

Google forms does provide the teacher to grade the students at the earliest.


Effectiveness at consumer level

OER consumers are typically teachers who want their students to learn concept mapping.

Linking a survey on three main constructs – Ease of Use, Concept Coverage and Concept

Complexity, can help in identifying the effectiveness of this OER at consumer level. This

has to be done as a follow-up activity.

Implementing Survey

Thus every user who downloads this resource will be asked their email address and as a

follow up the survey will be send to their email address.

The survey has been uploaded in google forms and can be retrieved.

Section 6: Building a Community of

BUCK CONVERTERS

Possible Sources for Community Building

Some of the viable sources for building a community are:

• Teachers who are teaching the subject of Power electronics;

• Teachers who plan to use information technology for their classrooms.

• Content developers who are trying to build efficient documents in the field of education

technology

Plans for Community Building

The resource is already available in the webpage and its access requires the users to provide

their email id. Thus there will be a list of interested users whom we can follow up using

email. All the interested users can then be connected using a local Wordpress.
