Clarke, David W. – Science Teacher, 2004
The use of complex instruments for chemical analysis is becoming increasingly important. Unfortunately, because of school budgetary constraints, many students are not exposed to these methods until they reach the college level. When students do have access to sophisticated instruments, they often view them as black boxes, with little or no…
