Knowledge of teaching STEM[T1]Knowledge of methods for effective STEM teachingTeacher/s
  • Mentioning or describing a pedagogical strategy or approach to each other (e.g. Think-Pair-Share)

  • Admitting to or showing evidence of becoming aware of a new pedagogical strategy/approach or describing a change in their own pedagogical knowledge

Confrontation: Problem is jointly recognised which forces individuals to reconsider their existing practice
Recognition of a shared problem space
[T2]Understanding of level of appropriateness of teaching methods and activitiesTeacher/s
  • Debating or grappling with how a pedagogical strategy or approach should be used (e.g. comparing different tools, adapting existing tools)

  • Describing their rationale or justification for selecting a particular pedagogical strategy or approach

Hybridisation: Melding of ideas and practices from different individuals in response to the identified problem in order to create a new practice
[T3]STEM content knowledge of individual STEM disciplinesTeacher/s
  • Talking about STEM content knowledge. E.g. mentioning topics (e.g. surface area) or mentioning science, mathematics, engineering or technology content in a general way

  • Explaining STEM content to one another other. E.g. one teacher explaining a STEM concept to the rest of the group, or the whole group explaining STEM concepts collaboratively

  • Engaging in a debate or argument about STEM content, grappling with a STEM idea, but not necessarily coming to any conclusion

  • Admitting to or showing evidence of becoming aware of either a gap in their STEM content knowledge and/or a change in their STEM understanding

  • Describing their rationale or justification for selecting a specific STEM content or topic to examine more deeply

  • Discussing using outside resources (reading articles, consulting national standards, contacting an expert, etc.) to deepen their STEM content knowledge

Crystallisation: New routines or procedures are enacted which embody what has been created or learnt
Hybridisation: Melding of ideas and practices from different individuals in response to the identified problem in order to create a new practice
