The LEMMA Project
A node of the ESRC-funded National Centre for Research Methods
LEMMA – Learning Environment for Multilevel Methodology and Applications
– www.cmm.bris.ac.uk
Research and training components

LEMMA Training
Capacity building in the analysis of data with complex structure
– Ultimate goal is to move learners to “take-off”, i.e. conducting and publishing multilevel analyses
Different modes of delivery– Face-to-face workshops (3-day + 5-day with time allocated to
analysis of participants’ data)– Face-to-face workshop followed by on-line mentoring– Training for established networks (e.g. university departments)– Web-based materials in a virtual learning environment

Lessons Learnt
Participants need to be motivated and have time to learn
– Best motivated are those with data and research questions that can be addressed through MLM
Experience of on-line follow-up and targeting established groups disappointing
Participants often do not possess pre-requisites for MLM (good understanding of multiple regression)
In practical sessions, tendency to focus on mechanics of using software rather than interpretation
5
Basic Principles
Accessible to anyone with basic statistics training (up to simple regression)
Modules to have 2 integrated components: concepts and practice
Facility for learner’s self-evaluation
– Pre-requisite quiz, and regular quizzes throughout materials
Collect data to evaluate materials and inform future training initiatives
– Basic user profile information collected on registration
– Quiz responses, webstats on patterns of use
Design materials so they can be easily modified by other trainers
6
Types of Material
5-minute video giving overview of content
Prerequisites with links to other online resources
2 linked documents: (i) Concepts and methods, and (ii) practice (MLwiN instructions with interpretation of output)
Quiz questions
Further reading (published research and other online resources)
Glossary
For each module:

Structure of Linked Documents
Concepts – 30-40 pages, split into lessons– Illustrative examples from mix of disciplines– Draw links between fitted model equations, graphs of
predictions and verbal interpretation – No reference to software– Expect other trainers to use with little change
Practice– Each Concepts lesson followed by exercises in MLwiN– Thorough analysis and interpretation of one dataset– Trainers can rewrite for other datasets and software
8
Core Materials
1. Types of variable2. Introduction to statistical modelling3. Multiple regression (single-level)4. Data structures5. Multilevel modelling of continuous data6. Logistic regression (single-level)7. Multilevel logistic regression
9
Future Materials
Substantive examples linked to core materials
Models for other types of outcome
– Nominal, ordinal, counts, duration
Models for non-hierarchical structures

The LEMMA VLE
Moodle Open source, widely used
– Open University is involved in it’s development
Has a good licensing model– Avoids annual fees– No restrictions on how many users– Sustainable
Does everything we need

Demonstrating the prototype
Encouraging engagement– Video overviews– Quizzes– Straw polls– ML Driver’s Licence
