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.
