Which of the following activities can be effectively demonstrated on a whiteboard?

The correct choice indicates that all of the listed activities can effectively be demonstrated on a whiteboard. This is because whiteboards are versatile tools that can enhance teaching by allowing for visual representations that aid understanding.

For intonation, a teacher can write sentences and use arrows or different sizes of letters to show the rise and fall in pitch when speaking, making it clear to students how to modulate their voice in different contexts. With spelling, a whiteboard is ideal for writing words clearly for students to see, allowing for an interactive spelling practice where learners can come up to the board and write the words themselves. Furthermore, when illustrating jobs, pictures can be drawn or printed and displayed on the whiteboard to help students visualize different professions, supporting vocabulary retention and contextual learning.

This flexibility and ability to convey different types of information—be it phonetic nuances, written language, or imagery—makes the whiteboard an effective educational tool for a wide range of teaching activities.
