Professional Development Practices for Vocational Education and Training

I have a six main article, about the Professional Development Practices for Vocational Education
and Training. Please I need to summarise each one of them as a dot point,
What is the article about and what the aim of the study of the research.
Later on I will be using this six article with my literature review research.
I will forward this six article one after one to you, and after the windup of the six you start the literature review research base of this article.
