Name: Teacher Phawat Organization: Lertsuthon School of Health Science ,Sukhothai Thummathirath Open University Title of paper: Classroom research series of lectures industrial hygiene: evaluation about hot measurement. The main purposes of this research study were about ( 1 ) Develop approach of teaching for new teacher is manual for teach in first year of research ( 2 ) Action research about approach of teaching in second year of research and ( 3) Reduce number fault test lower on 30% of total student . The series of lectures industrial hygiene: evaluation has difficult subject, fault test more than 30% and effect to retention on student. Methodology of research is naturalistic research: first year and action research: second year. In first year new teacher ( researcher) will observation professional teacher, finding data, partial teacher discuss and teaching. Researcher teaching and observation about finding to build approach of teacher .Research finding to develop approach of teaching and fault of practice testing 15.52%( N=277 students) minimum score 4 maximum score 20 mean 13.07 standard deviation 1 เอกสารประกอบ๗.๒.๕(๑) Page 1 total score 20,fault of subjective test 32.50%( N=277 students) minimum score 0 maximum score 5 mean 3.32 standard deviation 1 total score 5 .In second year teacher use approach of teaching, use power point and no power point and use manual paper annex of law.

INTRODUCTION local University was Opening first open university in 1978 , distance learning by book and multimedia, specific target group, multi-technology, เอกสารประกอบ๗.๒.๕(๑) a comprehensive evaluation of Sukhothai Thummathirath resource, the process.STOU is not have special normal practice class but training class and distance learning to region support student. Material support is teaching Page 2 the course, visual media, person support. Sukhothai tutorial or media support, Thummathirath special training. University(STOU) were open Teaching the course have university in Thailand, have book , practice book, audio mission to graduates and record human capital by life-long ,another practice tap,tellevision book in regional STOU education center.STOU regional Opening learning, built knowledge social and conserve Thai culture for organization, education center is important community about tutorial, coordination institution.STOU and solve problems, public distance relation integration course production and examination arrangement.

This is irreducible minimum drop out who would have dropped out for reasons control. beyond our Responsibility for student retention management importance very in distance learning for prevent drop out. เอกสารประกอบ๗.๒.๕(๑) have difficult 30% and effect to retention on student.4 METHOLOGY This research is Classroom research series of lectures industrial hygiene: evaluation about hot Page 4 measurement by naturalistic teaching research: first year ( N=277 about students on first semester on approach 2011) and action research: series of lectures industrial second hygiene: evaluation. year ( N=138 students on first semester on 2012) . In first year new teacher ( researcher) observation will discuss teaching. teaching about and Researcher and finding observation to build approach of teacher.
