First Pre-constructed MEL (pcMEL) project
Four teachers, two from Clark County School District in Nevada and two from school districts in New Jersey, teamed up with the PI and Co-I in the development of these MEL diagrams, with their supporting evidence texts and evaluation instruments. The project employed a design-based research methodology and occurred over three years.
We developed four pcMEL activities that focus on important topics in Earth and space science:
- Climate Change
- Earthquakes and Fracking
- Wetlands Use
- Formation of the Moon
The first MEL grant was supported by the National Science Foundation (NSF) under Grant No. DRL-1316057 and was part of NSF's Discovery Research K-12 (DRK-12) program.
Second Build-a-MEL (baMEL) project
- Do baMEL activities tested in multiple high school classroom settings promote critical evaluation, plausibility reappraisal, and scientifically accurate knowledge construction about controversial Earth and space science topics?
- How do these additional baMELs differ in promoting critical evaluation, plausibility reappraisal, and knowledge construction from pre-constructed MELs?
- To what extent does repeated use of both pre-constructed MELs and baMELs result in student engagement of scientific practices?
We developed four baMEL activities and four associated pcMELs that focus on important topics in Earth and space science:
- Extreme Weather
- Fossils and Earth's Past
- Freshwater Availability
- Origins of the Universe
The second MEL grant is supported by the National Science Foundation (NSF) under Grant No. DRL-1721041 and DRL-2027376 and is part of NSF's Discovery Research K-12 (DRK-12) program.
