In the interviews before both her lessons, Ann expressed that the students should learn
how to connect the diode correctly. But the core idea of Ann’s intentions was much
more focused in lesson 2 than in lesson 1 and the two lessons offered her students
very different possibilities to understand how to connect the diode. Even if she told
her students how, and why, it was important to connect the diode the correct way
in the first lesson, the meaning of the ‘correct way’ was not as obvious as in lesson
2. In the second lesson, several alternatives of connections were tested, and ‘right
ways’ were pointed out by contrasting them to ‘wrong ways’. Ann’s intentions then
became more in line with how she enacted the lesson.
