2013 Delivering Well Prepared Teachers Policy
The state should ensure that secondary science teachers know all the subject matter they are licensed to teach.
Arizona offers secondary certification in general science, and candidates are required to pass the NES General Science test. However, the state articulates that teachers with this certification are only allowed to teach general science, integrated science and thinking sciences.
Candidates applying for a secondary certificate are exempted from subject-matter testing if they have work experience in science, technology, engineering or math and a postsecondary degree or 24 credit hours of relevant coursework in the subject they intend to teach.
NES Test Requirements www.nestest.com Memo, April 12, 2007 http://www.azed.gov/wp-content/uploads/PDF/NewsBulletin_MiddleGradeApprovedAreas.pdf HB 2697 (2012)
Require secondary science teachers to pass a content test for each discipline they are licensed to teach.
Arizona should reconsider its testing exemption for candidates with STEM work experience, for content assessments are the only way to ensure that teachers possess adequate knowledge of the subject area. The state's intention to ease the path to licensure for those with STEM work experience is a good idea; however, passing a content test should be the bottom line, not coursework requirements.
Arizona recognized the factual accuracy of this analysis.
Specialized science teachers are not interchangeable.
Based on their high school science licensure requirements, many states seem to presume that it is all the same to teach anatomy, electrical currents and Newtonian physics. Most states allow teachers to obtain general science or combination licenses across multiple science disciplines, and, in most cases, these teachers need only pass a general knowledge science exam that does not ensure subject-specific content knowledge. This means that a teacher with a background in biology could be fully certified to teach advanced chemistry or physics having passed only a general science test—and perhaps answering most of the chemistry or physics questions incorrectly.
There is no doubt that districts appreciate the flexibility that these broad field licenses offer, especially given the very real shortage of teachers of many science disciplines. But the all-purpose science teacher not only masks but perpetuates the STEM crisis—and does so at the expense of students. States need either to make sure that general science teachers are indeed prepared to teach any of the subjects covered under that license or allow only single subject science certifications. In either case states need to consider strategies to improve the pipeline of science teachers, including the use of technology, distance learning and alternate routes into STEM fields.
Secondary Teacher Preparation in Science: Supporting Research
For an examination of how science teacher preparation positively impacts student achievement, see D. Goldhaber and D. Brewer, "Does Teacher Certification Matter? High School Teacher Certification Status and Student Achievement", Educational Evaluation and Policy Analysis, Volume 22, No. 2, June 20, 2000, pp. 129-145; D. Monk, "Subject area preparation of secondary mathematics and science teachers and student achievement", Economics of Education Review, Volume 13, No. 2, June 1994, pp.125-145; A. Rothman, "Teacher characteristics and student learning". Journal of Research in Science Teaching, Volume 6, No. 4, December 1969, pp. 340-348.
In addition, research studies have demonstrated the positive impact of teacher content knowledge on student achievement. For example, see D. Goldhaber, "Everyone's Doing It, But What Does Teacher Testing Tell Us About Teacher Effectiveness?" Journal of Human Resources,Volume 42, No. 4, Fall 2007, pp. 765-794. See also D. Harris and T. Sass, "Teacher Training, Teacher Quality, and Student Achievement". Calder Institute,March 2007, Working Paper 3. Evidence can also be found in B. White, J. Presely, and K.
