green engineering and environmentally-conscious manufacturing. Environmentalawareness discussions are included to make clear the perspective of why engineering studentsneed to learn about green design. The writing components in each course are more involved thanthose in other engineering courses.Whereas each course has undergone student and faculty assessments, an accounting of the resultsreveals similarities and differences in student reactions to environmentally considerate material.This paper includes numerical analysis of student assessments and faculty reviews for thepurpose of measuring progress towards common objectives. The paper also discusses qualitativedata for understanding the direction sustainable engineering education might take

end of this more in depth discussion, afew students were asked to rephrase what was discussed. If they could not make the links ormissed a concept, they were teamed up with another student and received peer help. The varioussteps of knowledge and links between concepts in this topic were as follows: Step 1: Lime (Ca(OH)2) is a base. Linkage 1: Addition of lime raises the pH. Step 2: Carbonates in water occur in various species (e.g., H2CO3, HCO3- and CO32-) Linkage 2: Raising the pH causes CO32- to be the dominant species. Step 3: Precipitation of CaCO3 is based on solubility where the product of concentrations of Ca and CO32- is always a constant. Linkage 3: When CO32- becomes
