Congratulations, you've finished Section 4!
This section covered skills for crossing when we are in a Situation of CONFIDENCE and we can determine when there is a crossable gap:
- considering whether to LOOK or LISTEN for the traffic.
Which procedure do you use when?
In Section 2 you learned about the Procedure to Develop Judgment of the Detection of Traffic which uses the TMAD to give students feedback to help them learn to recognize Situations of Uncertainty,
and now you've learned about Determining Gaps in Approaching Traffic.
Whew! Well, now you are ready to start the last section, which might be the most fun.
You've already covered all the essential information -- Section 5 has scenarios, frequently asked questions, and outside activities, all of which can help you process and apply what you've learned.
Some people are confused about which procedure should be used when, so this summary may be helpful.
- Timing Method for Assessing the Detection of Vehicles (TMAD):
The key word in the name TMAD is DETECTION.
The TMAD is used to assess the DETECTION of vehicles to find out if you have enough warning of their approach.
When would you want to assess someone's detection of vehicles?
You want to do that when you
- teach students to recognize when they can not DETECT vehicles with enough warning (that is, teach them to recognize Situations of Uncertainty);
- help students understand the effect of masking sounds on their ability to hear (DETECT!) approaching vehicles.
- Determining Gaps in Approaching Traffic helps train students for situations when they can see the vehicles in the distance.
So, you are not worried about whether they can detect the vehicles with enough warning, they can see them plenty far away.
You're worried about whether they realize
the vehicles are too close/fast to start their crossing.
Why would you have them practice Determining Gaps in Approaching Traffic? Because it helps your students learn to:
- recognize when they have enough time to cross even though they can hear or see vehicles approaching in the distance
(that is, recognize when the traffic is far/slow enough to allow them time to cross).
For example, we know that when Lorraine Evensen and her husband Dick were killed, she could see the vehicle that killed them approach from a distance.
If she had practiced Determining Gaps in Approaching Traffic, she probably would have realized that the vehicle was too close / fast to allow them time to cross (or she would have realized that at night, she is not able to make that determination).
