19th ICCE, Seoul, Aug. 12-17 (2006)

In the last nine years, we have designed, implement, and evaluated the systemic

approach to teaching and learning chemistry (SATLC)[1-4]. In continuing this work,

we have designed a new kind of objective test based on systemics, which is presented

here.

The questions in objective tests require a very short answer. The questions are

related to facts (thus, objective) which have unequivocal answers. Objective questions

can be multiple choice, true/false, and fill in the blank. The scoring procedure for an

objective test is completely specified enabling agreement among different scorers.

Traditional objective tests are usually good instruments examining the recall of

information and the application of terms, but they cannot assess learning beyond

comprehension. However, systemic objective tests can challenge students and

potentially can test higher learning levels (e.g., analysis, synthesis, and evaluation in

Bloom’s taxonomy [5,6]).

We illustrate here examples of systemic multiple choice questions that can form

the basis of conventional objective tests and which require a choice from a list of

possible systemic-related answers. Each systemic choice represents three to five

physical, or chemical relations, between concepts, atoms, or molecules.

Various types of systemic multiple choice questions from the fields of general,

organic, heterocyclic, and physical, chemistry are presented here.

CONCLUSIONS

We have shown how the ubiquitous multiple choice format for questions can

be adapted to evaluate student learning using the systemic method of teaching. These

kinds of questions probe the student’s ability to make maximum connections between

classical concepts, elements, compounds, and their reactions. Additionally, students’

recognition of patterns of connection instead of the individual convictions is an

important outcome of teaching and learning. Using systemic methods are important

outcomes of that process and the evaluation technique described here probes that

characteristic.
