This is a great question and one that is very important. If you are going to give a presentation on this topic, you will have to think about form and content. Let me make a few comments on each.
First, in terms of form, you might want to create a powerpoint presentation. Sometimes people respond better when there are visuals. You want to grab their attention and keep it. Also write out your presentation and go over it several times.
Second, in terms of content, you will seek to persuade parents that early intervention of parenting skill is important. For this to take place, you will need evidence. In light of this, let me suggest three points.
- Bring in some noted scholar's opinion in this area. If you can give a few quote or studies this will go a long way to convince people.
- Show some statistics and if they are more local, it would be great. In this way, things will hit home.
- People also like stories. So, give a few great stories that underline what you are talking about.
Finally, great presentations have a practical conclusion or application. Answer the the question, "What next?"
