## TMYN Levels The Playing Field

Average pre- and post-test scores for students in 106 courses that used TMYN.

Colors represent different Zpre values: red: students >1SD below pre-test mean for their course; yellow: average for students 0-1SD below mean; green 0-1 SD above mean; blue: >1SD above mean. Note the wide disparity among pre-test scores that is more than halved (from 49-24 percentage points difference) from pre- to post-test, illustrating the leveling of the playing field for students using TMYN

More than 3000 students were assigned

*The Math You Need, When You Need It* modules as part of 106 geoscience courses at a variety of post-secondary schools. Changes in from pre- to post-test scores suggest that the support leveled the quantitative playing field for all geoscience students. On average, both high- and low-performing students who fully participated in the use of TMYN as a part of their course showed learning gains, however gains were greater for students performed most poorly on the pre-test. Our findings emphasize that students who interact with context-specific quantitative problems can improve their mathematical skills, regardless of initial level of mathematical preparation.

## Effective in a variety of geoscience contexts

TMYN has been successfully used in a variety of higher education settings such as large research universities, regional universities, small liberal arts colleges, multi-campus urban 2-year colleges and small rural and suburban community colleges. TMYN has been used successfully in upper level courses such as Geomorphology, Hydrology and Field Methods, a variety of introductory level geology courses including Physical Geology, Environmental Geology and Earth System Science and other introductory geoscience courses such as Physical Geography, Meteorology and Oceanography. In each case, students improved their quantitative skills as measured by pre- and post-test changes.

## TMYN effectively remediates mathematics

Pretest score vs. Pre- Posttest difference (in percentage points)

Pretest score vs. Pre- to Posttest difference (in percentage points). Warm colors (red = more than 1SD below mean; orange = 0-1 SD below mean) indicate students who scored below their class mean on the pre-test; cool colors (green = 0-1 SD above mean; blue = more than 1 SD above mean) indicate students who scored above the class mean on the pretest.

Up to 57% of students arrive at college underprepared to perform mathematics at the level necessary to succeed in introductory geoscience courses which rely on numbers, data, equations, graphical representations, and other quantitative skills. Although some institutions have turned to prerequisites as a way to ensure appropriate preparation, these extra courses can place undue financial, temporal, and academic burdens on interested students, keeping them from enrolling in science courses that may interest them. As an alternative to mathematics prerequisites, TMYN helps students use mathematics in their geoscience courses.
