| Introduction|| |
| Training in Occupational & Environmental Medicine in India|| |
Most company doctors in India have not received any specialized training. They do a good job in delivering general medicine at the workplaces. Occupational Medicine though deals primarily with prevention. Hence special training, special knowledge and workplace skills are necessary. The need for training is well known and has often been discussed in this journal., , , .
Unfortunately the vast majority of company doctors cannot leave their work and join a residence program. The question which delivery mode is suitable to teach Occupational Medicine is therefore an urgent one. How can we reach the company doctors with our teaching?
This article discusses methods and good practices in distance education and online-teaching as one viable way to deliver high quality training in Occupational Medicine to employed company doctors in India.
| Adults as Students - a Challenge for Teachers|| |
The difference between adult learners and young students has been described in detail in numerous, easily accessible publications., , , ,  In summary, we can say that research has shown the following important aspects, which have direct bearing on our teaching in occupational medicine.
Adults - in contrast to young students - have many prior experiences and knowledge, they have tight personal schedules and are very practical and goal-oriented. They usually have a fulltime work and often cannot take off for months.
They want and deserve our utmost respect from us teachers. After all, would we be willing to put in another five to ten hours of learning every week for one year?
Adult learners need a guiding teacher more than a lecturer. They can learn and solve problems by themselves if we guide them, point out sources for solutions, show techniques to solve problems. For adult learners "learning how to do it yourself" is the goal and not "being told old solutions" which do not apply to their new and changing challenges. Then the problem-based learning will create significant learning experiences.
If the content is not connected to every day practice the chances of it being retained and remembered are very slim. To help the students learn and become better company doctors we have to measure our teaching by its value to solve the every day problems of company doctors in their companies. At the very end: we teach to improve every day practice, isn't it?
| How does Learning Work?|| |
Obviously we humans need different stimuli to learn things, especially when we make the transition from "just repeating knowledge" to high level tasks such as "analyzing" or "problem solving". Unfortunately these higher level skills are what is most needed for company doctors! These skills define our quality as adviser for management in questions of e.g. health problems, prevention of accidents and disease, absenteeism, choice of machinery, training program design, conflicts with workers on safety or health questions. Company doctors rarely need simple book knowledge.
To help adults learn we can look to what we know about the process of learning itself. Which teaching method helps most to remember and apply new knowledge? Research has shown that immediate use, practice by doing and discussion groups are the most powerful tools in teaching [Figure - 1]. Lecturing seems to be the weakest and most ineffective teaching method if we look at retention of content 24 hours after "being taught".
Problem-based learning is probably the most powerful tool in teaching Occupational Medicine that we have as teachers. Active learning techniques such as guided discussions, exercises, case studies, group work and presentations will use different learning capabilities of adult learners (such as seeing, analyzing, discussing, doing, applying and explaining) to engrain knowledge, develop problem-solving skills and develop professional attitudes. Help for teachers is easily at hand.,
| Consequences for Teaching Occupational Medicine|| |
- More interaction rather than lecturing will improve the retention rate and will develop skills on top of knowledge
- Different learning styles need different teaching and assessment methods to give each learner a chance to learn and to excel
- Practical training for hands-on skills will improve retention, reveal misunderstandings and will help company doctors to run Occupational Health Centers
- Applying the learnt content in new situations by working through problems and case studies will help develop practical skills in finding solutions and sharpen the analyzing and argumentation skills
- Regular presentations by students and team work are necessary to develop professional attitudes and communication skills e.g. for management meetings and report writing
- Development of professional attitudes towards standards and codes of conduct have to be in integral part of teaching company doctors
| Distance learning - A Practical and Effective Teaching Method|| |
Distance education is widely used in teaching all kinds of professional courses at undergraduate, graduate and even post-graduate level in other countries. In the US and UK some universities do not have a campus anymore, they deliver their training exclusively as distance learning courses. Masters courses in distance mode for occupational health & safety and occupational medicine (OSH) are available in other countries. Almost 100% of all postgraduate teaching in occupational medicine is done by distance education in the UK., In Australia a multitude of high quality masters programs in OSH can be done in distance education mode.
To balance the pro's and con's of either a purely residential or a purely distance education course a so-called blended course model seems appropriate for teaching Occupational Medicine. It has contact phases and self-learning phases. The knowledge transfer and studying can easily be done in the self-learning models at the learner's pace (e.g. in the evenings or weekends) with guided readings and assignments. The higher level skills like problem-solving, analyzing workplaces, ethical considerations, professional attitudes or team cooperation can be imparted in the contact programs.
Students' assessment and prevention of cheating is naturally a topic in distance education. Fortunately a lot of guidance is there from teachers' organizations and universities how to handle the problem., , , ,  Assessment techniques such as regular and frequent assignments, personal experience assignments (e.g. case discussions), essay type questions or students' portfolios can easily be used in distance and online teaching. To that range of assessments throw in the closed-book examinations at the contact programs, the assessment of practical skills during workplace visits and practical training, the case presentations and we have a good mix of multiple assessments which are hard to cheat without getting caught!
Online teaching as a sub-specialty of distance education is professionally developed and used in high quality teaching at graduate and post-graduate level around the world. Techniques and guidance is easily available for teachers in Occupational Medicine., 
| Evaluation and Feedback|| |
Teaching and learning thrives on feedback. Every course needs critique and feedback to grow, change and improve. Regular feedback from our customers, the students, on the quality of our teaching and the quality of the lecturers should be a normal part of our courses. Evaluating the impact of the course and the progress of the students helps to develop a "learning attitude" for both, the teachers and the students.
| Distance Learning in India|| |
Here in India distance education in OSH and Occupational Medicine is rarely used. Distance education in general is often perceived as being of low or no quality. Unfortunately that might be true in many cases. Some universities are trying to change that and are doing their best to introduce distance and online education seeing the enormous advantages such a course delivery mode has in a country like India.
Often students and teachers are falsely convinced that distance education means automatically part-time and low-quality education. If one looks at distance learning courses in other countries it is obvious that a full-time course means actually eight hours work per day for a student. The only difference is that the physical presence on campus is not required. The time required for a course is something the teacher decides, not the method. Therefore it is a perfect fit for our customers, the factory medical officers who work in companies all over the country.
The same applies to the quality. Low quality in distance education is a result of the teacher's quality and not of the inherent problems of the teaching delivery method. A multitude of courses for faculty are available to learn good online-teaching practices.
| Conclusion|| |
Distance learning, especially when used in blended courses, is an adequate delivery method for teaching knowledge, skills and attitude in Occupational Medicine. Here in India the need for training the huge number of doctors who already work in companies without any training is obvious. Part-time distance education coupled with contact programs for skills training and quality control can be a viable way to improve the quality of occupational health in the country. The quality of the teachers to deliver is crucial though.
The Indian Association of Occupational Health could play a leading role in expanding high quality teaching in Occupational Medicine. Important steps and analysis has already been done and published in this journal.,  We could contribute to the Government's goals to strengthen Occupational Health in India.
Develop a modern curriculum, organize teachers' training, standardize the course contents and the evaluations, develop nation-wide course objectives and define the professional levels which is required in each area of practice could all be topics to be taken up in an organized way.
| Example: a one year distance education course in occupational medicine|| |
The "PG Certificate Course in Occupational Health" conducted in Chennai, is a one year, web-based, blended course for company doctors.
Out of 500 total course hours about 170 (34%) are actually "distance-learning" i.e. self learning time for the students, 26 hours (5%) are workplace exercises in their companies and 224 (45%) are contact program hours. The project paper accounts for 80 hours (16%).
Every student has an experienced company doctor as tutor to support and facilitate the learning and help them through the course.
For the batch 2004-2005 four contact programs with 224 hours were conducted. They include e.g. workplace visits, patient examinations and clinical case discussions, hands-on training. The different teaching methods used in the contact programs are shown in [Table - 1].
The 34 weekly distance-learning modules (six hours each) include mandatory reading and assignments. In total the students had to send back 25 mandatory assignments for grading (including nine postings on the course web site) and could also finish nine voluntary assignments.
Internal assessment and quality control was accomplished with five internet-based tests, four closed-book examinations and three practical examinations (spirometry, audiometry, presentation) during the contact programs. The final examination is conducted as standard university examination. It includes two theory papers; practical and oral examination including spotters that had to be passed. External examiners are invited to insure quality. We had the honor to have Dr. Saiyed H. N. from National Institute of Occupational Health, Ahmedabad, and Dr. Ranga Rao from Central Labor Institute, Mumbai as examiners. During the practical training the students work usually in groups of three at audiometers, spirometers, industrial hygiene equipment (like sound level meter or pumps for dust measurement) and on computers (retrieve information from journals, databases on CD or internet). Every student individually or in small groups had to do approximately seven presentations to practice presentation and reporting skills. A project paper has to be written as a scholarly paper to be eligible for final examination.
In the middle and at the end of the year a course evaluation was requested from the students to get feedback on the course quality (content and conduct) and to measure the learning impact ("before" and "after" comparison). According to the feedback from the students this practice-oriented course had a enormous impact on their professional life and attitude.
