Animating Science Education
Dr Jocelyn Wishart, Graduate School of Education
Teacher Educator
This presentation is about how making stop motion animations as a way of
teaching science processes like waves, diffusion, life cycles, evaporation,
transfer of momentum, bonding, enzyme action etc. supports learning
Here are some examples https://www.youtube.com/watch?v=QI7o73mZObo

20 September 2013Introduction
It is now relatively quick and easy to create a short stop-motion animation in a science
teaching session using a digital or mobile phone camera, Plasticine or card, laptops and
freely downloadable software (iMotion, Windows Moviemaker).
Teachers and lecturers in different countries are seizing on the learning opportunities
offered by having students animate a science process yet there has been little research
into how and why this engaging activity supports learning.
Today I am reporting results from two
projects:
• observing the impact of teaching though
animation with school students of
different ages
• working with initial teacher trainees (both
primary and secondary) to explore exactly
how creating animations can be used to
teach about and reinforce understanding
of science processes.
3
20 September 2013What do we already know?
Using models is common in teaching science concepts, Harrison and Treagust (2000)
even wrote up a typology of the many kinds found. However, animation is much
more than a single model as it comprises a dynamic, visual and kinaesthetic multi-
stage modelling process.
Indeed Hoban and Nielsen (2013) consider all the different stages in creating an
animation to be important to learning. They speculate that each stage explores the
same concept but in different ways with meaning building from one representation
to the next to promote learning.
Also making animations is certainly engaging, as Hoban, Loughran and Neilsen
(2011) observed in both graduate student teachers and their primary school pupils.
However Ainsworth (2008) notes that animations themselves can detract from, as
well as, engender learning which reinforces Sutherland et al (2004)’s point that the
role played by the teacher in creating a culture for learning when employing
technology based activities is critical.

20 September 2013Research questions
About learning:
• Which activities within the process of creating stop motion animations and which
properties of the resulting animations promote effective learning?
And about teaching:
• How can learning activities involving stop-motion animations be effectively
deployed in teaching science at different levels?
• What issues in using digital and mobile phone cameras in schools and universities
do teachers need to engage with and what information do they need?
Study One 5
20 September 2013Participants
Participants were recruited through contacting teachers known to be interested
in research opportunities and eventually comprised students from four of their
classes
• grade 4 (25 students)
• grade 8 (26 students)
• grade 11 (25 students)
• grade 12 (9 students)
6
20 September 2013Methods Used
Each teacher chose to manage the lesson or sequence of lessons on animation
slightly differently however, in every case it was presented to the pupils as a way
of consolidating their learning on the current science topics.
Each lesson was followed by a questionnaire survey that asked students to rate
the different experiences during creating animations on a seven point scale
(where 1 represented not at all and 7 represented very, very much) once for
enjoyment and once for support with understanding the science.
The participating teachers were then interviewed using deliberately more open
questions that addressed the necessary preparation, the teachers’ perceptions
of learning that took place and any concerns they had about teaching in this
way.
Study One

20 September 2013What happened
Grade Four pupils spent the morning making animations to show how filters and
sieves work. They started by storyboarding their animations and then worked in
groups of 3 and 4 to create them using Powerpoint with one image per slide.
Finally, the teacher showed the class their work on the data projector.
The Grade Eight teacher took a much more open approach, the class had been
asked to prepare ideas for creating an animation on the respiratory and/or
circulatory systems. Students, working in pairs, then chose from Powerpoint,
Serif Draw Plus and Pivot. All animations were completed, this time in 60
minutes, and emailed to the teacher. They were not shown to the class.
There was much more time available to the Grade 11 teacher who devoted six
lessons to students creating animated stories with narrations showing their
understanding of a Physics topic of their choice. Student worked in groups using
Plasticine, digital cameras and Moviemaker. With more time models made by
this class were much more detailed and several incorporated human characters
and were well received at the playback session.

20 September 2013What happened
The Grade 12 teacher worked within a single 100 minute double lesson with a
smaller class using Flip video cameras (1 camera to 3 students) to make
animations to demonstrate the biological structures and physical processes that
enabled transport of proteins, sugars and fluids across animal cell membranes.
Again they were expected to research and write a short commentary to
accompany their video. Ten minutes before the end of the lesson the
animations were shown to the whole class via a data projector and used for
both discussion of biological functions and pointing out misconceptions.

20 September 2013What did the teachers say?
The teachers were concerned primarily with the students’ capability to use
the animation tools: cameras, laptops and software and the necessary
preparation.
Though all four teachers noted how making animations led to opportunities
for questioning whether for assessing students’ science knowledge and
understanding or for evaluating their progress.
Other strategies noted by the teachers included consolidation through
multiple opportunities for learning. One teacher noted the activities
matched VAK learning styles. When asked whether ALL the learning activities
were important to learning three of the four agreed however, the fourth
teacher prioritised the making of the models.
Study One
12
20 September 2013What happened
Making animations as a means of teaching and learning was introduced in three
universities in a 3 hour teaching session during which student teachers practiced
making animations themselves. In one university this was a voluntary session, in
the other two it was scheduled as part of their teacher education programme.
Students were then asked to report back on any opportunities they had in their
subsequent school placements to teach themselves by getting pupils to make
animations.
Data were collected at opportunity
throughout these activities using mixed
methods under a pragmatic approach.

20 September 2013Participants
Secondary science teacher trainees from two universities
• for video during making at university: Two groups of 3
• for interview following placement: 6
• in survey following placement:2
Primary teacher trainees from a third university
• for video during making: Two groups, a pair & a four
• in survey following placement: 11
Study Two
14
20 September 2013Methods Used
Qualitative data to give a rich picture of the student teachers’ learning was
captured through both video recording and post-placement interview.
It was also planned that quantitative data would captured through survey of the
student teachers’ pupils however, only one student achieved this.
Though a number of them completed a survey themselves.
Ethical considerations included
ensuring participation was fully
informed, voluntary and
remaining mindful of the need
to prioritise trainee’s work for
their ITE programme

20 September 2013Conclusions
Making animations in learning science is enjoyed by nearly all. It aids
understanding and memory in a number of ways:
• Visual and tangible representation of abstract science concepts
• Provision of opportunities to learn in different modes (or styles)
• Reinforcement through multiple stages in their production including
storyboarding, making, viewing and especially discussing
• Enabling teachers to 'see' what pupils know and understand
It was particularly useful for ITE students as it enabled them to focus on thinking
about how to explain or show concepts to others i.e. their future pupils.
As an ITE tutor I found it particularly useful in enabling me to explain science
concepts with the primary ITE students who had less specialist subject
knowledge than the secondary students.
22
20 September 2013Recommendations
Recommendations from participants focused mainly on preparation including
• trial making one yourself
• organisation of teaching groups
• checking means of image capture and transfer to the software
• fix the maximum number of images to be used in the light of time available
My advice from the teaching sessions
• don’t let plasticine get too cold
• avoid carpets
• don’t insist on storyboarding first
And finally, as several students said , “Just go for it”
23
20 September 2013Teaching resources
Guidance for ITE students and teachers in teaching science through creating
animations will be made available before Christmas at

Stemx13 Animating Science presentation J_Wishart

  • 1. Animating Science Education Dr Jocelyn Wishart, Graduate School of Education Teacher Educator This presentation is about how making stop motion animations as a way of teaching science processes like waves, diffusion, life cycles, evaporation, transfer of momentum, bonding, enzyme action etc. supports learning Here are some examples https://www.youtube.com/watch?v=QI7o73mZObo
  • 2. 2 20 September 2013Introduction It is now relatively quick and easy to create a short stop-motion animation in a science teaching session using a digital or mobile phone camera, Plasticine or card, laptops and freely downloadable software (iMotion, Windows Moviemaker). Teachers and lecturers in different countries are seizing on the learning opportunities offered by having students animate a science process yet there has been little research into how and why this engaging activity supports learning. Today I am reporting results from two projects: • observing the impact of teaching though animation with school students of different ages • working with initial teacher trainees (both primary and secondary) to explore exactly how creating animations can be used to teach about and reinforce understanding of science processes.
  • 3. 3 20 September 2013What do we already know? Using models is common in teaching science concepts, Harrison and Treagust (2000) even wrote up a typology of the many kinds found. However, animation is much more than a single model as it comprises a dynamic, visual and kinaesthetic multi- stage modelling process. Indeed Hoban and Nielsen (2013) consider all the different stages in creating an animation to be important to learning. They speculate that each stage explores the same concept but in different ways with meaning building from one representation to the next to promote learning. Also making animations is certainly engaging, as Hoban, Loughran and Neilsen (2011) observed in both graduate student teachers and their primary school pupils. However Ainsworth (2008) notes that animations themselves can detract from, as well as, engender learning which reinforces Sutherland et al (2004)’s point that the role played by the teacher in creating a culture for learning when employing technology based activities is critical.
  • 4. 4 20 September 2013Research questions About learning: • Which activities within the process of creating stop motion animations and which properties of the resulting animations promote effective learning? And about teaching: • How can learning activities involving stop-motion animations be effectively deployed in teaching science at different levels? • What issues in using digital and mobile phone cameras in schools and universities do teachers need to engage with and what information do they need?
  • 5. Study One 5 20 September 2013Participants Participants were recruited through contacting teachers known to be interested in research opportunities and eventually comprised students from four of their classes • grade 4 (25 students) • grade 8 (26 students) • grade 11 (25 students) • grade 12 (9 students)
  • 6. 6 20 September 2013Methods Used Each teacher chose to manage the lesson or sequence of lessons on animation slightly differently however, in every case it was presented to the pupils as a way of consolidating their learning on the current science topics. Each lesson was followed by a questionnaire survey that asked students to rate the different experiences during creating animations on a seven point scale (where 1 represented not at all and 7 represented very, very much) once for enjoyment and once for support with understanding the science. The participating teachers were then interviewed using deliberately more open questions that addressed the necessary preparation, the teachers’ perceptions of learning that took place and any concerns they had about teaching in this way. Study One
  • 7. 7 20 September 2013What happened Grade Four pupils spent the morning making animations to show how filters and sieves work. They started by storyboarding their animations and then worked in groups of 3 and 4 to create them using Powerpoint with one image per slide. Finally, the teacher showed the class their work on the data projector. The Grade Eight teacher took a much more open approach, the class had been asked to prepare ideas for creating an animation on the respiratory and/or circulatory systems. Students, working in pairs, then chose from Powerpoint, Serif Draw Plus and Pivot. All animations were completed, this time in 60 minutes, and emailed to the teacher. They were not shown to the class. There was much more time available to the Grade 11 teacher who devoted six lessons to students creating animated stories with narrations showing their understanding of a Physics topic of their choice. Student worked in groups using Plasticine, digital cameras and Moviemaker. With more time models made by this class were much more detailed and several incorporated human characters and were well received at the playback session. Study One
  • 8. 8 20 September 2013What happened The Grade 12 teacher worked within a single 100 minute double lesson with a smaller class using Flip video cameras (1 camera to 3 students) to make animations to demonstrate the biological structures and physical processes that enabled transport of proteins, sugars and fluids across animal cell membranes. Again they were expected to research and write a short commentary to accompany their video. Ten minutes before the end of the lesson the animations were shown to the whole class via a data projector and used for both discussion of biological functions and pointing out misconceptions. Study One

  • 11. 11 20 September 2013What did the teachers say? The teachers were concerned primarily with the students’ capability to use the animation tools: cameras, laptops and software and the necessary preparation. Though all four teachers noted how making animations led to opportunities for questioning whether for assessing students’ science knowledge and understanding or for evaluating their progress. Other strategies noted by the teachers included consolidation through multiple opportunities for learning. One teacher noted the activities matched VAK learning styles. When asked whether ALL the learning activities were important to learning three of the four agreed however, the fourth teacher prioritised the making of the models. Study One
  • 12. 12 20 September 2013What happened Making animations as a means of teaching and learning was introduced in three universities in a 3 hour teaching session during which student teachers practiced making animations themselves. In one university this was a voluntary session, in the other two it was scheduled as part of their teacher education programme. Students were then asked to report back on any opportunities they had in their subsequent school placements to teach themselves by getting pupils to make animations. Data were collected at opportunity throughout these activities using mixed methods under a pragmatic approach. Study Two
  • 13. 13 20 September 2013Participants Secondary science teacher trainees from two universities • for video during making at university: Two groups of 3 • for interview following placement: 6 • in survey following placement:2 Primary teacher trainees from a third university • for video during making: Two groups, a pair & a four • in survey following placement: 11 Study Two
  • 14. 14 20 September 2013Methods Used Qualitative data to give a rich picture of the student teachers’ learning was captured through both video recording and post-placement interview. It was also planned that quantitative data would captured through survey of the student teachers’ pupils however, only one student achieved this. Though a number of them completed a survey themselves. Ethical considerations included ensuring participation was fully informed, voluntary and remaining mindful of the need to prioritise trainee’s work for their ITE programme Study Two
  • 15. 15 20 September 2013Findings From the PGCE student survey (n=13) (they were asked to give up to 5 words to describe the activity) Study Two
  • 16. 16 20 September 2013Findings From thematic analysis of ITE student video recordings using nVivo 4 students, 25 minutes Discussion unclear, 8 minutes Study Two
  • 17. 17 20 September 2013Findings From thematic analysis of ITE student video recordings using nVivo 2 students, 20 minutes 3 students, 53 minutes Study Two
  • 18. 18 20 September 2013Findings Detail from thematic analysis of ITE student video recordings using nVivo Thinking as a teacher (n=11) Enhancing pupil understanding 6 Preparing to teach through animation 4 Assessing pupil understanding 3 Making animations seen to motivate pupils 2 Issues with time needed for making animations 2 Storyboarding would help pupils plan 1 Considering need for scaffolds according to class ability 1 Debating curriculum level of animation 1 Accessibility of learning through animation 1 Any process can be animated 1 Highlighting possible misconceptions 1 Study Two
  • 19. 19 20 September 2013Findings Benefits of making animations reported by ITE students in post-project interview (n=6) Freq Aids pupils' understanding 9 Enables teachers to 'see' what pupils know 6 Animation is fun, engaging, enjoyable 6 Aids learning to teach by helping us think about how to explain or show concepts to others 4 Relevant to all age groups 4 Enables pupil creativity 2 Enables science thinking 2 Enables teachers to challenge & interest pupils in science 2 Models how scientists work 1 Enables multiple learning styles 1 Aids active learning 1 Study Two
  • 20. 20 20 September 2013Findings Issues with making animations reported by more than one ITE student in post- project interview or survey (n=19) Freq Amount of necessary preparation 10 Resources (availability and knowing how to use them) 10 Available time 8 Finding a curriculum subject opportunity 4 Watch the number of photos being taken 3 Watch out for camera shake - tripods? 2 Clear timings 2 Managing other PGCE work 2 Lack of confidence 2 Children's ability (lack of) 2 N.B. 4 students reported no issues, recommending “Just go for it” Study Two
  • 21. 21 20 September 2013Conclusions Making animations in learning science is enjoyed by nearly all. It aids understanding and memory in a number of ways: • Visual and tangible representation of abstract science concepts • Provision of opportunities to learn in different modes (or styles) • Reinforcement through multiple stages in their production including storyboarding, making, viewing and especially discussing • Enabling teachers to 'see' what pupils know and understand It was particularly useful for ITE students as it enabled them to focus on thinking about how to explain or show concepts to others i.e. their future pupils. As an ITE tutor I found it particularly useful in enabling me to explain science concepts with the primary ITE students who had less specialist subject knowledge than the secondary students.
  • 22. 22 20 September 2013Recommendations Recommendations from participants focused mainly on preparation including • trial making one yourself • organisation of teaching groups • checking means of image capture and transfer to the software • fix the maximum number of images to be used in the light of time available My advice from the teaching sessions • don’t let plasticine get too cold • avoid carpets • don’t insist on storyboarding first And finally, as several students said , “Just go for it”
  • 23. 23 20 September 2013Teaching resources Guidance for ITE students and teachers in teaching science through creating animations will be made available before Christmas at http://www.bristol.ac.uk/education/research/sites/animating-science/.
