Introduction

Background – what’s the problem?

What do students want?

What did we provide? Quizzes and feedback

What next?

Background

10 years teaching physical geography at LJMU

Many geoscience students lack confidence in numeracy

What can we do to improve both numeracy and confidence?

Develop Blackboard quizzes

Supported by HEA subject centre for GEES

Royal Society’s Advisory Committee on Mathematics Education report:

bbc.co.uk (14th June 2011)

Glaciology exam question: “estimate the average velocity across the glacier”

Velocities are ca. 10, 12 & 8 m/yr (0 at sides)

One student’s answer…

Answer = 24.5 How on earth??10 + 12 + 7.6 = 24.5

3

What the students said (n=25):

Were you happy with your numeracy skills prior to university?

Yes = 35% No = 65%

Do you think you are expected to have greater numeracy skills than you currently have?

Yes = 70% Not sure = 10% No = 20%

Do you think that there are too many numeracy tasks in your modules?

Yes = 70% No = 30%*

Would you use online support on Blackboard?

Yes = 65% Maybe = 25% No = 10%

What the students said (n=25):

What kind of help would you would find useful?

“It would be good if students could attend an hour session a week or alternatively students should be able to go to their tutor”

“To know there is some kind of support if needed. Maybe a lecturer to be available to go through certain tasks if you find them difficult? Or information on blackboard about what numeracy you need to know and how to do it.”

What we have provided:

Suite of Blackboard quizzes Organised into 9 numeracy topics Three levels of difficulty (intro, inter, adv) Anytime, anywhere, self-paced learning Supportive feedback to enable learning Subject-based examples to demonstrate relevance Tagged with subject categories (glaciers, fluvial,

soil, climate…)

Blackboard settings:

Feedback is only given at the end of a quiz, not after each question, so max 5 questions per quiz

Show user their score, submitted answer, correct answer and feedback

Allow multiple attempts (to build confidence)

The importance of feedback:

Face-to-face tuition is time consuming Quiz feedback is a great way to help students learn

where they went wrong Detailed feedback for wrong answers showing the

right answer and working out Can be specific to each wrong answer for MCQs We give feedback for correct answers too in case it

was a lucky guess!

Right answer feedback:

How did the students respond?

150+ invited, 32 students have enrolled Of those, only 10 have completed quizzes One student did 11 of them 3 students completed the evaluation questionnaire Found quizzes useful? 1/3 SA, 2/3 A

Learnt something new? 2/3 A, 1/3 SD

Improved confidence? 1/3 A, 2/3 N ‘Useful as it jogged my memory. Could use more

guidance on trigonometry’

Advice & recommendations:

Setting up the quizzes is easy but there is quite a high faff factor in doing all the feedback, categories, settings, key words etc.

It is not easy to get the level right (intro, inter, adv)

It is easy for mistakes to slip in unnoticed... e.g. specifying which is the correct answer to a MCQ

Beware of potential traps e.g. numerical answers can’t include any text (e.g. the correct answer is 10 not 10m)

Where to next?

How to get more students to use them? How to get more staff to recommend them? Embed quizzes into skills or subject modules Offer drop-in workshop sessions for students to do

the quizzes with someone there to support them Exchange quizzes with other universities/depts

Any comments or feedback welcome!
