Many learners expressed a wish for more courses

Teachers’ observations Learners had inadequate skills in maths – could not calculate percentages without assistance and did not understand proportions They were weak in terms English language reading and comprehension, and general knowledge They had a difficulty with abstract thinking and little analytical skill (at least partly due to language) These weaknesses required much teacher – learner interaction Nevertheless, they were generally highly motivated to increase their knowledge practical skills

Conclusions By their own admission, the learners acquired a lot of new knowledge, but they will need more practical experience under supervision to become proficient and confident in fish identification Considering their educational background, the novelty of the subject and the duration of the course the learners performed well There is a need to develop a more user-friendly fish identification tool
