Dimension: Lesson Phases
DefinitionLesson phases are the different stages in the teaching and learning process (Beerenwinkel & Börlin, 2014). In the Lesson Phases Coding Manual, we defined 12 different categories. In these categories, in addition to the base codes, we developed codes for classroom intervention events (from codes a to e). Researchers can conduct a comparative analysis between regular classrooms and intervention classrooms through the use of video tutorials, virtual reality, games, or other activities to intervene in instruction. 
NotesCoding guidelines
Instructions of use
Observation and coding should start with a clearly recognizable action, e.g. when the teacher starts to introduce the topic or to create groups for students. For example, from timestamp 00:01:21 the teacher starts to introduce the topic of the lesson, until timestamp 00:03:35 when the teacher ends the phase. In this situation, we can code this phase as the introduction. The next phase should directly start at timestamp 00:03:36. There should be no gaps or intervals period between each phase, this is because intervals are students or teachers wrapping up the content or activity of the previous phase. Following this, the teacher will start a new phase through clear instructions and actions. Coding ends when all instructional activities are completed.
Notes on Saving Coding Files
We recommend a unique naming for each coding file, which should include the name of the recording, the observation number, and the name of the coding manual, e.g., VidXXX_01_lesson_phases.
