Strategies for the future
Towards the end of the Elf Camp we had an open discussion on future strategies of the Boot Camp, in the context of increased demand from potential participants. (We had done 5 Boot Camps in the previous 12 months.)
Some of the main points from the discussion were:
Trainers workshop, KL, 7-11 December 2015
We had 12 participants for the 5-day "Elf Camp" plus Ian Signer, Ngumbang and Mike as facilitators.
The first 2 days were devoted to learning principles, a framework for assessing lessons, and questioning techniques. Most of the time in the last 3 days was taken by practice lessons run by participants followed by feedback from the rest of the group. This brought up lots of suggestions for ways to improve the activities.
The 5-day format was much better than the 2-day sessions we have run for elf training in the past, and will be the format of choice for the future.
Learning Styles : VARK
Using learning styles to "tailor" teaching to students with different learning preferences does not result in better learning. A pitfall of the approach is that learners pigeon hole themselves and tend to disregard information presented in styles which do not correspond to what they think is their style. In view of this, we will drop the VARK approach.
The best ways to present material depends primarily on the type of material, not the "type" of learner.
Since there are many good ways to present material and individuals do learn in different ways, we will continue to use a wide range of methods to get concepts across.
We are now looking at ways to prepare Boot Camp participants for the activities they will do.
Why Bayes first?
In Bangkok in July 2015 we ran a revamped Boot Camp introducing Bayesian analysis before frequentist and information theoretic (AIC) methods.
We scrapped NHST in 2013 and confidence intervals were downgraded after Dec 2014.
Frequentist methods seem simple and intuitive, but the intuitions are wrong: a p-value is not the probability that null hypothesis is true, a confidence interval is not a credible interval. For details see Gigerenzer, Hoekstra, Morey...
The Bayesian approach is intuitive and the intuitions are correct. It can be taught at elementary level, eg Albert & Rossman. The impression that Bayesian methods are difficult comes when people turn to Bayesian analysis when they encounter problems that cannot be solved with frequentist methods: the Bayesian approach works, but it's not going to be simple.
We no longer have to worry about Bayesian methods being criticized as "unscientific". A bigger worry is that a tradition of using uninformative priors seems to have taken hold in ecology.
