You could connect an update query to the checkbox (or button). That is what I would do. Whether you want to do this by macro, or code, depends on your VBA skills.

If you need help with a VBA solution, you need to give some more information on your table structure, and your layout.

Let's assume that your Main Check Box is named chkPresent. The following code, in the AfterUpdate() Event of chkPresent, will Check/Uncheck all Check Boxes on your Form depending on whether or not chkPresent is Checked. Is this what you are looking for?
Expand|Select|Wrap|Line Numbers
  1. Private Sub chkPresent_AfterUpdate()
  2. Dim ctl As Control
  3.  
  4. For Each ctl In Me.Controls
  5.   If ctl.ControlType = acCheckBox Then
  6.     If ctl.Name <> "chkPresent" Then
  7.       ctl.Value = Me![chkPresent].Value
  8.     End If
  9.   End If
  10. Next
  11. End Sub

In the afterUpdate event of the checkbox:
Expand|Select|Wrap|Line Numbers
  1. Docmd.SetWarnings(False)
  2.   Docmd.Runsql("UPDATE tbl_Students SET TempAttendance = " & Me.ChckBox);
  3. Docmd.SetWarnings(True)
  4.  
Note that this will set the TempAttendence field for ALL records in teh table. If you need to only do it for some records, you will need to add a WHERE clause.
