Getting it right: on-line formative assessment of numeracy skills
Aims of the project
• To assess the underlying numerical abilities of students within our second year course
• To improve these skills• To support development of ability and confidence
in solving numerical problems
Numeracy question from examination paper
Relationship between A’ level grades and numeracy score
Pre-Practical Quizzes
• Completion required prior to attendance in lab
• Short series of questions on moodle - theoretical
and numerical
• Pass mark of at least 60%
• First trialled in second year Molecular Biology
Support for numerical questions
• Numeracy helplines
• Practice quizzes
• Answer files
• Videos
Numeracy Helplines
• Designed by students
• Simple explanations
• Equations to memorise
• Worked examples
Numeracy helplines
Help line usage
Practice quizzes
Practice quizzes
• 193 students on course
• 302 separate attempts
• Over 200 views of the answer files

Advantages of on-line support resources
• Used at anytime and repeatedly• Regular practice of numerical concepts • No fear of embarrassment• Immediate results/feedback• Helps us to identify areas of weakness which
require additional support
Comparison of equivalent questions on molarity and percentage solutions
Analysis of numerical results
Student feedback
Summary
• Continued practice at numerical problems has had a positive effect
• The support materials are appropriate and well utilised
• Thanks to UCL for funding the creation of our support materials
