Knowledge Development Presentation 1 – IDC

padi-emblem-open-water-diver

The Knowledge Development Presentations that make up the IDC are to prepare you for when a student answers a question wrong in a knowledge review. There is a procedure to follow that will allow you to help the student understand why they got the question wrong and what the correct answer is.

My first KDP is taken from the Open Water Knowledge Review Chapter 4 Question 11:

Why can’t you or your buddy share a dive computer?

Introduction

(state who you are, your number and what you will tell them)

Hi, my name is JumpSailDive and I am your instructor. My number is #1234567890. (These should be written on the board). Can I just ask you a question?

Contact Statement: (this should be in the form of an analogy)

How many of you had to share something with a sibling, like a computer or an iPad? It’s frustrating isn’t it? You want to use it when they are using it and vice versa. You both can’t have it at the same time. Perhaps you want it set up in specific ways, your own backgrounds, using it for private messages with that girl you like in your French class. It just doesn’t work does it?

Value: (why this is important information relating to diving)

This is like sharing a computer when diving. If one of you has it, it will be recording and tracking everything that person is doing. No two people will ever dive the same profile and this is where the problem lies. Because a few feet/metres difference can cause you to go past your no-decompression limit and that is a safety risk.

Application: (how and when we will use this information)

Now as you are all diving with computers, when we do Open Water Dives 3 and 4 we will take a moment on the dive to compare each others’ computer. Then when we get back to the dive shop we will download the data to the laptop and have a look at the different dive profiles that we dived on the same dive.

Key Points: (topic)

Today we are talking about dive computers and why we can’t share them.

Conduct: (what you want the students to do during the presentation)

Now take out your copies of “How to Use and Choose a Dive Computer” and turn to page 8. Take a moment to read the paragraph there.

Body

Objectives:

Why can’t you or your buddy share a dive computer?

Show the prescriptive slide and then return to the question slide and show the answer. Discuss with the students and answer any questions that they have.

Example of actual diving circumstances/Application to local environment:

So when we go diving on the HMS Maori, we will do both Open Water Dives 3 and 4. During those dives we will check each others dive computers (I will tell you when to do this), looking at the NDL, the current depth, max depth and time.  Once we are back at the dive shop we will download the data from our dive computers to the laptop and and have a look at the different profiles.

Example from PADI Continuing Education:

So as you are becoming competent in using a dive computer you might consider doing an Enriched Air Nitrox course. This would give you the benefit of increasing your bottom time as it reduces your nitrogen exposure.

Related dive equipment to promote:

The dive computers that you are borrowing for this course are a fantastic piece of kit. If you notice that ever instructor here has one, it is highly recommend that you get one especially if you are planning on doing the EANx course.

Dive travel experience to promote:

Now don’t forget about our upcoming live-aboard to the Maldives. Free EANx refills are included so now might be the time to do that EANx course to take advantage of the deal.

Summary

Reinforce value with application:

So this is important information to know because we will be using this on Open Water Divers 3 and 4. Checking each others’ dive computers at depth to see if there are differences in max depth, current depth, NDL and time. When we return to the dive shop we will also check the dive profiles logged by your computers. It is a big safety concern to share a dive computer. No two people will dive the exact same profile and by following one computer you risk putting yourself over the no-decompression limits and your risk of DCI could increase.

Review key points: (the answer)

Show the answer to the question and go through it.

Restate the objectives:

So we’ve now answered the question and know that you shouldn’t share a dive computer.

Promote Con-Ed, equipment and travel:

Now don’t forget about the upcoming live-aboard trip in the Maldives, where they are giving free EANx refills. So take advantage of the EANx diver course before you go and you can try out your new computer while you are there.

Let’s see how this goes. I will update tomorrow once I get my score……

UPDATE 19/10/2013

So I did my presentation. I scored 4.7 out of 5 (or 28 out of 30). That is a definite pass. I lost a total of 2 points. The first was that I didn’t interact enough (I should have had more questions with the students – though the course director couldn’t give me any concrete examples of questions that I could have asked).  The second that my non-diving teaching aid wasn’t good enough.

I could complain and say that she was being pedantic about it all, but it was a near perfect score on my first attempt. Woohoo. Now I have 2 more practice ones to do before I do the IE.
