Teacher Gender and Student Achievement - Evidence from gender mixed co-teacher pairs WORK IN PROGRESS Louise Beuchert Aarhus University Tryg. Fonden’s Child Research Centre
THIS PAPER • Exploits eksperimental data combined with register and survey data about students and their teachers • Question 1: The relationship between same-gender teacher and student achivement – Shows that boys taught by a male teacher have sign. higher achievements – Gender inequality in education (Bertrand & Pan 2013; Goldin et al 2006) (OECD 2015) • Question 2: Implications for policy? - 70% of school employees are female (DK) Flexible policy: male co-teachers/aides Shows that boys seem to benefit when introducing a male co-teacher, compared to a female co-teacher, in female-taught classrooms.
OUTLINE • • • Data Empirical strategy: Student FE model Results: Teacher gender Introduce policy eksperiment with co-teachers Results: Co-teacher pairs Conclusion and future research
LITTERATURE • Data development: linking students and teachers – Student FE + Teacher FE – Revise importance of teacher characteristics (Ladd et al 2008; 2016) – Hanushek 1997; Goldhaber 2008; Ladd et al 2016 • Having a same-gender teacher seem to benefit students – Student FE models – Dee 2007; Ladd 2008; Cho 2012; Winters, Haight, Swaim and Pickering 2013 – Primary/middle school
DATA • Data from the Danish Co-teacher Experiment – – – See Andersen, Beuchert, Kjærgaard and Nielsen (2014) Large-scaled RCT 221 schools Representative sample of Danish public schools All 6 th grade classes (10, 199 students) (age 12) • Register each teacher in Danish and Math – – Personal identifiers: teachers, students, co-teachers Link each teacher and student (New in DK!) Link with register data and survey information Register data yearly, from before school start
EMPIRICAL STRATEGY • Do students who are taught by a same-gender teacher have higher academic performance? – Exploit within-student across-subject variation – Subject 1: Boy taught by Female teacher – Subject 2: Boy taught by Male teacher (i. e. same-gender) • Estimation sample: Identifying variation <- - MIXED
EMPIRICAL STRATEGY •
EMPIRICAL STRATEGY •
(i) The effect of a SAMEGENDER teacher does not depend on the subject taught • Think of this as –. . role model effects etc. work in the same way –. . the teacher applying same teaching strategies etc. • In paper: – – Teacher surveys, 85% response rate Teaching strategies across subjects/teacher gender

FIGURE 2. TEACHING BELIEFS IN DANISH AND MATH BY TEACHER GENDER
ii) Students are assigned teachers based on the same mechanisms across all subjects (within schools) • Think of this as. . – – Students are assigned to classrooms on the basis of their average ability/motivation, not subject-specific • Classes formed when enter grade 0, stays throughout grades 0 -9 • <2% move class during Potential threats: DK: Not • Tracking: low performing GIRLS assigned FEMALE teachers allowed • High ability BOY moved to MATH class taught by MALE • Parental bias towards teacher gender/subject (Grönqvist and Vlachos 2014) – Registerdata: Parents’ edu/empl. mesured before school start – OLS: Teacher char. on parents’ baggrund, interact w/subject – F-tests: jointly insignificant, not different across subjects
RESULTS: OUTCOME • Outcomes: grade 6 national test in reading and math • Danish national tests – Mandatory testing program in grades 2 to 8 – End of the year-test – Online and adaptive test system • Questions adapt to the students proficiency during the testsession • Advantage: No teacher-assessment (reduce teacher bias) – Standardized (mean 0, std 1)
RESULTS: THE EFFECT OF A SAME-GENDER TEACHER
RESULTS: THE EFFECT OF A SAME-GENDER TEACHER • The estimated effects are robust when including. . – Teacher FE – Teacher controls measured before students start school (e. g. HS GPA, credentials, experience, income, children) • Results in line with newest evidence from Student FE models - e. g. Dee 2007; Ladd 2008; Cho 2012; Winters, Haight, Swaim and Pickering 2013; Grönqvist and Vlachos 2014;
RESULTS: THE EFFECT OF A SAME-GENDER TEACHER • The effect of a same-gender teacher is larger among. . – Children of parents living apart in the year of birth – Firstborn children – Girls of low educated mothers
MECHANISMS AND POLICY • Boys seem to benefit academically when taught by a male teacher compared to a female teacher • Mechanisms / Channels – Role model effects /Stereotype threats (Hinnerich 2013; Beilock et al 2010; Antecol 2013; Lavy and Sand 2015) – Teacher bias • in grading (Lavy 2008; Mechtenberg 2009; Falch and Naper 2013; Rangvid 2014) • In ”behavior” in class (Bertrand Pan 2013; Cornwell et al 2013; Kristoffersen et al 2015) – Males just better teachers? (In paper: registerdata track in/outflow)
MECHANISMS AND POLICY • Policy – Female-dominated professions: Child care (94%); Schools 70%; after school program 75%; youth club 52% – Student-teacher gender interactions in the classroom • e. g. awareness of own teacher bias, teaching strategies etc. (OECD 2015) – Regulation of the teacher pool • e. g. teacher college enrollment, recruitment programs etc. • Change margin of inference?
CO-TEACHER POLICY • More flexible: Male co-teacher/aide in the classroom • Introducing co-teachers – – – – – The Danish Co-teacher Experiment (Andersen et al. 2014) Randomly assigned to 35 schools Teacher educated The teacher and co-teacher prepare and teach the class in cooperation 10 lessons per week/class In Danish and math ~1 school year (Oct. -June) Co-teacher gender not randomly assigned Search and hire between Aug. 5 th –Oct 1 st
CO-TEACHER POLICY • Extension of the same empirical strategy: – Within-student across-subject variation in gender combinations of the co-teacher pairs • Illustration of variation (Danish classes) % of students 20 % 15 % 59 % 3 % Gender combination Female teacher w/ male co-teacher (mixed gender) Male teacher w/ female co-teacher (mixed gender) Female teacher w/ female co-teacher Male teacher w/ male co-teacher
CONCLUSION AND FUTURE RESEARCH • Achievement of boys are significantly higher when introducing a male in the classroom • Boys introduced to a co-teacher pair of mixed gender benefit significantly more compared to having a co-teacher pair of two females – Female teacher w/ Male co-teacher: 0. 27 SD – Male teacher w/ Female co-teacher: 0. 16 SD . . without harming the achievement of girls! • i. e. closes 6 th grade avg. reading gender gap: 0. 11 SD • Future research: Replicate experiment with randomisation of teacher char. (e. g. Papay et al 2016)
