"While I agree all are important, I feel the most important factor in good PBL is a great driving question. If you find the right questions then most of the other factors identified are covered automatically. How do you generate a great question and who is the right person to generate that question?"

Great ideas for factors and multiples

The OECD's Programme for International Student Assessment (PISA) has just published Let's Read Them a Story! The Parent Factor in Education. The document is worth looking at in its own right both as educators and as parents. I have one quibble with it - which you may read about in my blog-post. Thanks!

"DRAFT: Promoting Grit, Tenacity, and Perseverance-Critical Factors for Success in the 21st Century We face a critical need to prepare children and adolescents to thrive in the 21st century-an era of rapidly evolving technology, demanding and collaborative STEM knowledge work, changing workforce needs, economic volatility, and unacceptable achievement gaps. This report takes a close look at a core set of noncognitive Factors-grit, tenacity, and perseverance-that are essential to an individual's capacity to strive for and succeed at important goals, and to persist in the face of an array of challenges encountered throughout schooling and life."

"Development of technology within the classroom can aide the identification of contextual factors that may or may not contribute to effective use of technology in enhancing quality learning experiences. factors such as organisational culture, teacher self-efficacy and their confidence and experience in utilising technology, resources and learner engagement all have to be considered to allow for an integrated approach."

David Jakes on the key factors to consider when developing strategic use of technology.

Between the fall of 2011 and the spring of 2012, people across the United States suddenly found themselves unable to get their hands on A.D.H.D. medication. Low-dose generics were particularly in short supply. There were several factors contributing to the shortage, but the main cause was that supply was suddenly being outpaced by demand.

Most schools that have integrated laptop computers and other digital devices into learning are not following the paths necessary to maximize the use of technology in ways that will raise student achievement and help save money, a report concludes."We all know that technology does things to improve our lives, but very few schools are implementing properly," said Leslie Wilson, a co-author of the study, "The Technology Factor: Nine Keys to Student Achievement and Cost-Effectiveness," released last month. She is the chief executive officer of the Mason, Mich.-based One-to-One Institute, which advocates putting mobile-computing devices into the hands of all students.

Results of a study published in Neurology that adds weight to the idea that dementia onset can be delayed by lifestyle factors such as reading writing, exercise and diet.

1. OWNERSHIP is key. For this project, the students were not listening to me on why Twain was or was not a racist, they were showing me and the rest of class what they thought. They were invested in winning their argument. They knew that their work was going to determine if he was guilty or not. Although I gave the assignment, the students were in charge the rest of the way. It was their project and they wanted to do it win. When students feel they own what they are doing, they will work harder. When the audience is larger, they want to impress everyone. These are not crazy ideas, they are the results of owning the work they are doing. OWNERSHIP is a major factor in the value of PBL. 2. CREATIVITY is the another major part of the PBL and is closely linked with OWNERSHIP. Students were allowed to be creative in their work as a lawyer or witness. Witnesses needed to stay within character, but could add their own elements on the witness stand. Allowing the students to create gives them a bigger sense of OWNERSHIP. 3. Another part of the PBL is the COLLABORATION. Students were working with each other trying to decide the best plan of attack. Witnesses would meet with their lawyers and discuss how the questions they were going to ask and how they should dress. The Jury worked on group projects researching the previous public opinions on Twain and his writing. Students were sharing ideas freely with one another. I had three sections of American Lit at the time, so I had three trails running. Lawyers would help others in the other classes and trash talk the opposing lawyers as well. It was all in good fun, but the collaboration had students working hard with one another to accomplish this goal. 4. Depending on how you set up your project, CRITICAL THINKING, is also an important part of PBL. With my Twain Trail, students needed to think about both sides of the argument. Students needed to prepare their witnesses for potential cross-examination questions. They needed to

Two Harvard researchers looked at the factors that actually improve student achievement and those that don't.

"Classroom management is a whole process. Being a teacher, you have to keep an eye on a number of factors to make your class organized, disciplined and managed. You have to deal with noisy students, disruptive students and late students."

A huge factor for schools in dealing with students and working online is CIPA/COPPA compliance. This is to ensure student safety as well as monitor and filter their online behavior.
