Question

there are new students at your school and you want to help them learn to open their combination locker. you created the visual models below. decide which two models would be ineffective for students.

Explanation:

1. The first model (mind - map - like with scattered text bubbles): It lacks a clear, sequential structure. Students need a step - by - step guide for opening a combination lock, and this model's disorganized text bubbles don't provide a straightforward sequence, making it hard for students to follow the steps in order.
2. The fourth model (text - heavy paragraph): It presents the instructions as a long paragraph. For students, especially those new to opening combination locks, a paragraph - form instruction is difficult to parse quickly. They need clear, separated steps, and a long paragraph doesn't visually separate the steps, leading to confusion about the order of actions (like when to turn left, right, and how many times). The second model (table - like with clear step - by - step and action boxes) and the third model (visual lock steps with numbered and action - labeled locks) are more effective as they clearly show the sequence of actions.

Answer:

The first model (with the blue "How to Open a Combination Lock" circle and scattered text bubbles) and the fourth model (the text - heavy paragraph about opening the combination lock) would be ineffective for students.
