I believe in the power of classroom teaching and learning to address the inequities we face in society. And I think that reading is at the core of all learning and should be at the center of every classroom.

Iserotope is where I tell some stories and share some of my thoughts. Don’t be shy: Join the conversation. You’ll be happy you did!

Here’s a little more about what this blog is about:

Making Reading More Visible
After spending 15 years in the classroom, this is my fifth as an instructional coach. Focusing on literacy at the high school level, I’m helping teachers put reading at the front of their practice.

By high school, many people think that it’s too late to teach reading. They’re wrong. It can and must happen, or else students who are behind will never catch up. I’m trying to make reading more like writing — to treat it as a craft, to make it more public and less secret, to push teachers and students to get their reading out into the world.

Making Reading More Fun
Reading shouldn’t be drudgery. It shouldn’t feel like medicine. It should be fun because it is. I’m excited to continue the work my colleagues and I have begun to build classroom libraries and to promote independent reading. It’s extremely rewarding.

Giving Teachers Voice
Too many people are talking about education without asking teachers what they think. We need to hear more from teachers. TEACHER VOICES aims to fill the gap.

The Kindle Classroom Project
I’m also building the Kindle Classroom Project (with the help of generous supporters!), in which students read books they like on Kindles they get to bring home. There are now more than 1,400 students participating in the project. You might get so excited that you’ll want to donate your used Kindle or contribute books to the e-library!

Iserotope Extras
I’m always reading and sharing high-quality articles about education, reading, race, and culture. Iserotope Extras is a compilation of some of my favorites. Please check them out and tell me what you think.

    I like your website. I share many of your interests and passions. I found your website searching for AoW examples, but I found myself reading a ton of your posts. Nice job.

    I wasn’t sure where to post this but I thought you would like it. For a class, I had to answer the question, “What is your vision of a lifelong learner?” This is what I wrote.

    My friend Mark Isero is a lifelong learner. His blog, iserotope.com, is a constant reflection and inquiry about “teaching, reading and technology.”

    One entry about the homework debate included quotes from several articles, parents, and education reformers. It is clear that he is constantly learning, reflecting and leading others by engaging them in critical thinking.

    My vision of a lifelong learner is someone does just that. True learning is a process that requires examining critical issues from multiple view points. Then coming to various possible conclusions, solutions and further questions for research. And finally engaging others in a productive discussion that stimulates and moves newly inspired and better informed people to action.

    I feel alive and energized when I participate in these activities and that’s why being a lifelong learner is fun.

      So kind, Mr. Mercer! You’re not so shabby yourself! I respect and appreciate very much the stance you take as a teacher, ally, friend, and learner.

Please share your brilliant insights!
