For the past 20 years, I have been using project based training methods to teach applied project and program management to mid-career path professionals in the oil, gas, mining, telecommunications and international development sectors in SE Asia, the Middle East and Africa with considerable success. The approach we use is blended learning- combined face to face and distance learning mode, spread over a 26 week period.
While these individuals are nearly all engineers/technical people, working full time, we have found that the real benefit is not only in enhancing their competencies in using the tools & techniques of project management, but helping develop the “soft” skills- leadership, problem solving, motivating, conflict resolution- teaching people working in a virtual team environment how to get people to do what they committed to do while having little or no formal authority over others on their team.
Not sure if this would help anyone in a high school or grammar school environment, but would be happy to share my lessons learned.
