We report on an international study about mathematics students' ideas of how they will use mathematics in their future study and careers. This builds on our previous research into students' conceptions of mathematics. In this paper, we use data from two groups of students studying mathematics: those who participated in an in-depth interview and those who completed an open-ended questionnaire. We found that their responses could be grouped into four categories: don't know; procedural skills; conceptual skills; and professional skills. Although some students held clear ideas about the role of mathematics, many were not able to articulate how it would be used in their future. This has implications for their approach to learning and our approach to teaching. © 2011 National Science Council, Taiwan.

The Mars Science Laboratory Rover Curiosity has observed calcium sulfate veins in all of the bedrock examined to date in Gale Crater, with the exception of the Bradbury Rise area. The veins are also ubiquitous in the Murray Formation, which is interpreted as fine-grain mudstone. But recently when the rover reached the Murray Buttes on the lower slopes of Mount Sharp, the presence of light-toned rocks with moderate CaO have been observed, suggesting the presence of a cementd porous sandstone. The substantial increase in ChemCam analyses consistent with cemented sandstone (instead of mudstone), along with changes in other sedimentary structures may signal a change in the depositional environment and/or provenance of the lake deposits.
