Data can be a huge motivator for both teachers and students. As educators, it's important that we help our students learn to analyze their own data and use it to set personal goals throughout the school year. In my classroom (9th grade Algebra), for example, my co-teacher and I would grade all Unit Exams, and provide students with a 'Mastery Tracker'. This tracker broke up the test into ~5 to 8 specific learning objectives, and students were asked to chart their percentage of mastery for each objective. This simple activity gave students clear visibility into their progress, strengths, and weaknesses, and helped them set measurable growth goals going forward. Instead of saying, "I got a B- on the Unit 5 exam," students were discussing which specific objectives they had down, and which they needed help with. This was also hugely valuable to us as teachers since we could use the data to group students into thoughtful re-teaching pods.
