2. We will be discussing about grammar on the next lesson.
Hi Niwantha,
Sentence #1 is grammatically correct. We can use the preposition "in" to describe a period or duration of time.
Example: In the next lesson, we will be discussing on gerunds. / The flowers are in full bloom in summer.
Hope this helps.
Cheers, Lance
