The tutor's job: find out what they think first

In simple words

A good tutor is like a guide on a hike. Before the walk, the guide asks, "Where are you starting from?" If you start the lesson from where the learner really is, they can follow you. If you start from where you wish they were, they get lost.

Before this course: Genetics & Evolution: evidence (course 15.5.3). You can already decode a gene, sort mutations, test a cross with chi-square, use Hardy-Weinberg and weigh the evidence for evolution. You also finished Biology Systems: body systems (course 15.5.2). Now you learn to teach all of this to someone else.

Key facts

Active learning works better than listening alone. A meta-analysis of 225 studies of undergraduate science, engineering and maths courses found that exam and concept-inventory scores rose by 0.47 standard deviations with active learning, which the authors say is about 6% on an average exam. Failure rates averaged 21.8% with active learning and 33.8% with traditional lecturing (Freeman and others, 2014, PNAS).
In that paper, active learning means learning that "engages students in the process of learning" through activities or discussion, instead of "passively listening to an expert". Traditional lecturing means "continuous exposition by the teacher" (Freeman and others, 2014).
Check the maths (Python): 33.8 / 21.8 = 1.55, so learners in lecture-only courses failed about 55% more often. That matches the paper.
A tutor's three jobs in every session:

Job	What it looks like	Bad habit it replaces
Diagnose	Ask the learner to explain or draw an idea before you teach it	Starting with a 20-minute explanation
Teach	Short explanation, then the learner does something with it	Talking until the time runs out
Check	The learner answers a new question without help	Asking "Does that make sense?"

Good diagnostic prompts ask for an explanation, not a yes or no: "Draw what happens to a sugar molecule after you eat it." "Why do you think bacteria become resistant?" "Explain to me how a gene becomes a protein."
The tutor's promise: the learner does the thinking. You ask, listen, explain briefly and give practice. You do not do their homework.

Step by step

Before the session, pick one topic from courses 15.5 to 15.5.3 (for example, protein synthesis).
Write three diagnostic prompts that ask the learner to explain, draw or predict.
Start the session with a prompt, then stay quiet for at least a slow count of five while they think.
Write down their exact words. Do not correct them yet.
Circle anything that is wrong or missing. That becomes your teaching plan.
Teach for no more than 5 minutes, then give them a task (decode a sequence, label a diagram, predict a result).
Finish with one new question they have not seen. Check: they can answer it without your help.

Try it now

Record yourself (audio only is fine) explaining one biology idea to a friend or family member for 10 minutes. Afterwards, count how many minutes you talked and how many they talked or worked. Rewrite your plan so they do at least half of the work.

I'm learning "Biology Tutor: teach" on The Future Market. Lesson 1: "The tutor's job: find out what they think first".

What the lesson teaches:
- Active learning works better than listening alone. A meta-analysis of 225 studies of undergraduate science, engineering and maths courses found that exam and concept-inventory scores rose by 0.47 standard deviations with active learning, which the authors say is about 6% on an average exam. Failure rates averaged 21.8% with active learning and 33.8% with traditional lecturing (Freeman and others, 2014, PNAS).
- In that paper, active learning means learning that "engages students in the process of learning" through activities or discussion, instead of "passively listening to an expert". Traditional lecturing means "continuous exposition by the teacher" (Freeman and others, 2014).
- Check the maths (Python): 33.8 / 21.8 = 1.55, so learners in lecture-only courses failed about 55% more often. That matches the paper.
- A tutor's three jobs in every session:
- Job - What it looks like - Bad habit it replaces
- Diagnose - Ask the learner to explain or draw an idea before you teach it - Starting with a 20-minute explanation
- Teach - Short explanation, then the learner does something with it - Talking until the time runs out

The exercise I'm working on:
Record yourself (audio only is fine) explaining one biology idea to a friend or family member for 10 minutes. Afterwards, count how many minutes you talked and how many they talked or worked. Rewrite your plan so they do at least half of the work.

I'm stuck. Please:
1. Explain the main idea in plain, simple words with one everyday example.
2. Walk me through the exercise one small step at a time. Ask me what I've done so far before giving the next step.
3. Don't just give me the final answer. Help me do it myself, and check my work when I share it.

I'm a parent helping my child (about 8 years old) with a lesson called "The tutor's job: find out what they think first" from the course "Biology Tutor: teach".

Here's what the lesson says:
A good tutor is like a guide on a hike. Before the walk, the guide asks, "Where are you starting from?" If you start the lesson from where the learner really is, they can follow you. If you start from where you wish they were, they get lost.

The activity:
Record yourself (audio only is fine) explaining one biology idea to a friend or family member for 10 minutes. Afterwards, count how many minutes you talked and how many they talked or worked. Rewrite your plan so they do at least half of the work.

Please explain this so an 8-year-old understands: short sentences, a fun everyday example, and no hard words.
Then give me 3 simple questions I can ask my child to check they understood, and a way to do the activity together, one tiny step at a time.
