"I am sorry, I don't understanding 'temporary repeated action', and why you have said 'Present consequence of a completed event in the past at an unspecified time or a state which commenced at a point of time in the past and continues until the present time and in all likelihood will continue into the future time?' I haven't understood. Please help me!"

The language used by teachers to explain time reference, particularly of verb forms, can be confusing for the students. Timelines are neat devices that can be used to clarify our teaching language. Timelines enable the communication of sophisticated concepts to the lowest level of learner, and can prompt sophisticated discussion amongst higher level learners.

This article is a basic introduction to timelines. Later articles will discuss when to use timelines in class, concept checking, activities and strategies that use timelines and their potential drawbacks. This introductory article covers the following areas.

What is a timeline?
One of the keys to learning a language is learning how that language refers to, and describes, time and events, or states, that occur in the realm of time. In English, this reference to time is most commonly described by the verb, in its various tenses and aspects. Unfortunately, when learning a language, it is at times difficult to understand the concepts that are given as explanation.

Timelines are diagrams that illustrate the reference to time made by a given piece of language. They are used to show how a particular language item (often a verb in a particular tense and aspect) places particular events or situations in time and in relation to other events.

Why use timelines?

The concepts which underline time reference in a language are often difficult to explain using controlled language and are often linguistically difficult to understand. Timelines are used to explain language in the more universal form of pictures, diagrams and symbols. Most people will follow the direction indicated by an arrow.

Timelines are used to:

       Simplify linguistic explanation

       Reinforce the understanding of a concept

       Illustrate the differences between verb forms and other language items

       Help students with a visual learning style

       Provide a reference point for students

       Encourage awareness of how language refers to time in different ways

What does a timeline look like?

There are no set rules for the appearance of timelines, rather, there is a common sense convention which will be described below. Teachers will have there own idiosyncrasies and develop their own micro styles (representing time through diagrams is never going to be a standard affair), however, the similarities between the timelines used in Room 12 in London and Room 14 in Shanghai are greater than the differences.

The basics

A horizontal line represents the basic line of time. The left end of the line is the first point in time, the right end is the final point in time. Thus, time is deemed to move forward as the line moves from left to right.

This line is usually marked with a point that represents now. Thus, the timeline is divided into the past and the future.

To emphasise the direction of time, the line may be capped with an arrowhead. I also like to represent Now with a triangle, as below.

This simple template can then be added to in order to show everything from the difference between the words before and after and the meaning of the future perfect continuous!

Symbols

The following is a summary of the common symbols used on timelines

Examples

Here are some timeline examples demonstrating the use of these symbols.

       Yesterday, I met Bob in the bank, quite by chance. 
 

       Last night, I was walking home when I slipped on the icy path
 

       I have been learning Japanese for three years.

       I have been to New Zealand, Iceland and Taiwan.

 
       I get up at seven o'clock every day.

 Conclusion

These examples should show how the symbols act to illustrate a sentence or phrase. In the second article you will see how to use these diagrams in class, in particular how to use them to check the understanding of key concepts.
