Doctoral dissertation
The method of lesson structure analysis was introduced in my PhD thesis entitled Video-based analysis of mathematics classroom practice: Examples from Finland and Iceland
Teachers College, Columbia University, 2008

Large studies using lesson structure analysis
Search for structure in diversity Trends in International Mathematics and
Science Study (TIMSS) (1995, 1999) In 1999, 638 classes in 7 countries
participated Study found that there are many paths to
success The Learner’s Perspective Study (LPS)
(2006) More qualitative in nature Focused on lesson events, not the whole
lessons

Benefits of video in classroom research1. Enables the study of complex social
processes 2. Helps eliminate the say/do discrepancy
3. Lessens recorder bias
4. Increases inter-coder reliability
5. Permits unlimited reanalysis

Benefits of video in classroom research6. Allows for multiple viewpoints 7. Facilitates integration of qualitative and
quantitative methods
8. Enables richer reporting of results
9. Exposes mechanisms and antecedents
10. Can be reduced to lesser forms of event portrayal

Video in professional development of educators1. Illustrate various levels of thinking
2. Highlight effective practices
3. Show examples of student misconceptions
4. Provoke conversations about a problematic teaching moment
5. Focus on specific aspects of teaching
6. Provide a “common ground” experience
![Page 7: Video-Based Analysis of Lesson Structures](https://reader035.vdocuments.mx/reader035/viewer/2022062521/5681690f550346895de02642/html5/thumbnails/7.jpg)
Video in professional development of educators7. Contrast cases
8. Provide visions of what is possible
9. Compress experience
10. Support role-playing
11. Predict/see what happens
12. Build categories of pedagogical phenomena
13. Enable leaps in time scales
(Pea & Hay, 2003)

Problems with video analysis
1. Verisimilitude and camera effects
2. Privacy and confidentiality
3. Educational colonialism
4. May be too persuasive, “seductive”
5. Missing contextual information
6. Evaluation of video research

Why Finland and Iceland?
Cultural and political similarities In PISA 2006, Finland ranked #1 in
mathematics and science, #2 in reading Despite spending lots of money per student,
Iceland’s scores were below average in reading and science and just above average in mathematics
Icelandic gender “problem”

Methodology
Twenty schools—ten in each country—participated
Two lessons per teacher were analyzed, although often three were taped
Two cameras in the back of the classroom
Lesson structure analysis using Videograph
![Page 12: Video-Based Analysis of Lesson Structures](https://reader035.vdocuments.mx/reader035/viewer/2022062521/5681690f550346895de02642/html5/thumbnails/12.jpg)
Lesson structure analysis
Two dimensions: Function and Form
The pedagogical functions of lesson elements are based on Herbart’s (1835) cyclical sequence of learning steps (review, lesson, practice)
The categories for the forms of classroom interaction are sample-sensitive and stem from asking: Who is doing what? How are the participants interacting?
![Page 13: Video-Based Analysis of Lesson Structures](https://reader035.vdocuments.mx/reader035/viewer/2022062521/5681690f550346895de02642/html5/thumbnails/13.jpg)
Lesson structure analysis
The first pass categories are fixed (review, introducing new material, practice, other), the second pass categories are sensitive to the sample
The method offers a way to investigate the different forms of classroom interaction by which teachers attempt to achieve their pedagogical goals
One of the strengths of this open-ended method is its ability to capture unique, yet often subtle classroom practices

Research questions
Does the video-based method of lesson structure analysis presented in this report extend the sensitivity of existing methods of lesson structure analysis such as those used in the TIMSS and LPS studies?
Does the video-based method of lesson structure analysis presented in this report permit structural comparison of Finnish and Icelandic mathematics lessons?
Is it feasible to conduct meaningful video-based pedagogical research on a small scale?
![Page 16: Video-Based Analysis of Lesson Structures](https://reader035.vdocuments.mx/reader035/viewer/2022062521/5681690f550346895de02642/html5/thumbnails/16.jpg)

Some findings
Despite the small sample size, some national patterns and cross-national differences were detected
The Finnish lessons essentially followed the conventional Review-Lesson-Practice-script, whereas more than half of the Icelandic lessons exhibit versions of Individualized learning, a learner-based instructional philosophy
Finnish lessons exhibited more classroom interaction, while many Icelandic lessons consisted only of one-on-one tutoring and no whole-class interaction

Individualized learning
Should not be minimally-guided (Cognitive load theory)
Could be a factor in the decline of Icelandic students’ academic achievement scores
Could be a factor in the Icelandic gender question
