Hello and thank you sincerely in advance for your help. I'm an aspiring English teacher trying to learn the ins and outs :)

I am trying to arrange the most effective structure for a lesson plan exercise I have come up with a structure that makes sense for me (in blue) as well as an explanation.

If you would be so kind, could you please look at my lesson plan structure and explanation, and give me some feed-back on what could be improved?

PART FIVE - TEACHING AND LEARNING

A. Below are different stages in an English language lesson that aims to develop reading and speaking skills. The lesson centers around a written text that discusses The Greenhouse Effect on the planet. However, the order of activities is illogical.
Order each of the activities to make the lesson flow.
Write a brief rationale explaining why you have chosen your particular order.

For example: I have placed activity X after activity Z because students will need to understand that language before moving on to the next task.

Activities:
a) The teacher gives students a task that checks detailed understanding of the text.
b) Students talk about what they know about the greenhouse effect and how it affects the planet.
c) The teacher gives students a task that checks general, overall understanding of the text.
d) Students discuss their ideas of how the greenhouse effect could be reduced in their countries.
e) The teacher clarifies the meaning of important vocabulary items in the text.
f) The teacher gives the students the text.

Here is how I've structured these activities and why:

Activities:
f) The teacher gives the students the text.
e) The teacher clarifies the meaning of important vocabulary items in the text.
b) Students talk about what they know about the greenhouse effect and how it affects the planet.
d) Students discuss their ideas of how the greenhouse effect could be reduced in their countries.
c) The teacher gives students a task that checks general, overall understanding of the text.
a) The teacher gives students a task that checks detailed understanding of the text.

Explanation: Some educators might prefer to place activity b) first to test student knowledge, but a topic like the Greenhouse effect might be too complicated for some students. Therefore, I would place activities f) and e) first to familiarize all students not only with the topic but also with important vocabulary necessary to discuss the topic. I would place activities b) and d) afterwards to give students a chance to express their ideas on the topic using the learned important vocabulary. At the end, I would place activities c) and a) to check studentsí knowledge about the learned subject and vocabulary.

What are your thoughts on how I've structured my lesson plan? Thanks again.
