Technical verb vocabulary of physics teachers is poor, suggests action research study
An action research study on 25 physics teachers from Rajasthan during their lesson presentations during an interview revealed that none of them used more than 30 per cent of the verbs from the standard physics textbook written in proper technical language. All physics teachers failed in their 'technical verb vocabulary' test. None could even score 33 per cent cut off mark.
The study has implication for proper training in the use of technical language specially the verbs. Some other studies have probed that vocabulary knowledge of physics teachers closely correlates with quality of teaching and problem-solving success of teachers themselves. The abstract of the study done by this investigator for contribution to a seminar goes as follows.

An observational action research study of physics postgraduates in Jaipur during their presentation part of selection for college job revealed that they had an extremely low command (80X20) on technical verb vocabulary. The criterion of effective command is 80X80, meaning thereby that 80 per cent students using 80 per cent correct technical verbs. For example, all the candidates invariably spoke 'move or travel' instead of 'traverse' ; 'go up' instead of 'rise'; 'tell' instead of 'describe', etc.

The study had the following objectives: (i) To find the current status of technical verb vocabulary command of physics topics and (ii) To suggest induction training for acquisition of a minimum technical verb vocabulary for professional verbalization of physics content.

The action research methodology of direct observation and jotting down the verbs spoken during presentations (N=20; age: 25-30 years; presentation duration: 10 minutes) and their technical appropriateness. It was found that 80 of the candidates could use 20 per cent physics related verbs appropriately.

The post-selection discussion (N1=3, duration=15 minutes) revealed that the present teaching of physics at higher education level was reflective of poor verbal skills of teachers and confining to telling-listening-selective cramming-writing for examination. It was suggested that a verb bank of 50-60 words from a standard textbook should be prepared as part of two-hour in-house induction training of selected five physics teachers. Consequently, a one page document is available for newly recruited teachers to be well-versed with technical verbs of physics.
