A formula in a spreadsheet is copied from cell B1 to cell C2. If the original formula is =$A2, which of the following best represents the resulting formula?

Back

=$A3

Answer explanation

Option C is correct because when a formula is copied to another row with a dollar sign in front of the column letter, the cell address updates only by the row number. The dollar sign acts as an anchor to the row number or column letter that it is in front of when you copy the formula or cell address to another cell. Option A is incorrect because a formula with an anchoring dollar sign always presents with a dollar sign in its placement when it is copied. Option B is incorrect because the address of the cell is not what is being copied. Option D is incorrect because the dollar sign in front of a column label protects that value in the formula from changing.

Back

A technology applications teacher is preparing a class to begin work on a group project. Which strategy is most effective in facilitating collaboration and teamwork among group members? Options: Separating girls and boys into different groups, Limiting each group to three members, Emphasizing group harmony as the most important goal, Modifying group norms as the situation requires

Back

Modifying group norms as the situation requires

Answer explanation

Option D is correct because flexible group norms should be established so that the groups do not become rigid and intolerant or develop sub-groups. Option A is incorrect because the best groups have an equal number of boys and girls. Option B is incorrect because groups should be midsized. Small groups of three or less lack enough diversity and may not allow divergent thinking to occur. A moderate size group of four to five is ideal. Option C is incorrect because group harmony can override the necessity for more critical perspectives.

The teacher primarily understands the importance of implementing which of the following objectives of information literacy?

Back

Students comprehend the legal and social implications of using information.

Answer explanation
