Micro forging

In contrast,Chapter 11 looks at the very recent introduction of computer-based multimedia technologies into chemical education as a way of forging macro/sub-micro/symbolic links. Chiu and Wu discuss the value of such approaches as, respectively, a modelling tool, a learning tool, an assessment tool and an instructional tool. Their thesis is given added weight by the inclusion of results from classroom development and evaluation projects.

An additional problem is that in chemistry we are concerned with the forging of links between specific types of narratives, situations, and the chemical substances that contribute to their explanation. The latter can be progressively considered at the macro level (e.g. as the white solid commonly called salt and, in its chemical context, sodium chloride ), at the sub-micro level (e.g. as a lattice of sodium and chloride ions), and at the corresponding symbolic representational level (e.g. (Na " Cl )s)- The depth of the understanding acquired will be related to the level of the explanation reached. 

Additionally, given the lack of technologies available to early modem chemists, any possible link that could be forged between microstmcture and experimental findings were tenuous at best and did not warrant the assumption that either atoms or fundamental corpuscles were involved at the micro-level. Thus, seventeenth...
