Apprentices deal with different types of tables such as load charts for determining load weights. In technical training, tables often contain information unique to the trade and apprentices may have difficulty both understanding the information in the table and the way it is organized. It is important to teach how the table is organized as well as the information contained in the table.
Instructors can ask apprentices questions that require them to locate information using the table features.
Questions to teach table structure
- What is the purpose of this table? Locate the table heading and decide what the table is about.
- List the 5 kinds of wire rope slings in this table. Use subheadings and/or diagrams to locate the information required.
- Highlight the column that gives information about 2-leg bridle hitch with a 45° horizontal sling angle. Understand how the information is organized horizontally and vertically.
- A worker is using a single vertical hitch with a 1 ¼ inch rope. What is the working load limit? Use headings, rows and columns to locate the answer.
- How do you calculate working load limit for a double choker hitch? Use details such as additional information or notes.
- What happens to the working load limit for a single basket hitch with legs inclined as the angle decreases? Understand the relationship between columns and rows.
Asking questions based on table structure helps you to identify the concept an apprentice is struggling with, for example, understanding table features. Ultimately, apprentices will be able to apply their understanding of table structure to tables when they are introduced.
