iPads in Science Class

So your school has purchased a class set of iPads and you want to be able to use them in a meaningful way. And, finally, the school administration has lifted the ban on personal devices and cell phones are allowed in the classroom under the supervision of teachers.  What do you do?

Panic? No.

First, begin considering how smart phones and ipads/tablets can complement what you do in the classroom.  Students are engaged by the technology and, if well managed, the devices will become an incredible learning tool.  You need to demystify the cell phone.  If you are planning to use cell phones in class, ask the students to place their cell phones on the corner of their desks in full view.  This is where the phone stays unless it is being used for educational purposes.

Second, consider your teaching style and what is it that you want to achieve. Does your teaching style primarily make use of lecture or do you focus on collaborative activities or are you somewhere in the middle?  Your teaching style will determine what types of apps you will choose to use. The three types of apps are generally "productivity apps",  "interactive apps", and "reference apps."

Productivity apps allow students to create.  Interactive apps require students to work with the app to receive feedback. Reference apps provide information but don't require the students to interact or input anything.

If your style is more lecture focused, then you will probably use reference apps periodically where as if you use collaborative activities you may find the productive and interactive apps more appealing.  It really depends on your style.

Third, limit yourself to two to three apps per course.  Don't underestimate the learning curve of the app; always allow the students to play with the app for homework before working with it in class.  Ensure the app is used for meaningful learning not just playing with technology.

Fourth, after you try the app out as a learning activity, be sure to assess its use.  Ask the students if the app provided a beneficial learning experience.

So, pick an app, test drive it and determine if it can provide a meaningful learning experience.  Here are some mostly free subject specific apps from iTunes:

UDL, Science and Flipping!

UDL again.  Flipping again. And, if you keep reading - a great Google Doc!!

Universal design's focus is that barriers to learning are removed and all students have equal access to the curriculum.

Reducing the number of students in the margins.  Sounds good.  Hard to argue.

The flipped classroom affords time to teachers so they can spend more time with students and have more of an opportunity to discover the barriers to learning.  When you teach high school science in a full year school (one that is an IB school for example) it is hard to get to know the 200 students you teach.  So time is gold.

Flipping gets you that time.

Flipping to me is way more than vodcasts.  It is strategically using "out of class" activities (vodcasts, interactive simulations, screen-casts, case studies, virtual labs, etc.) to motivate students to become engaged during the "in class activities." 

So some tools to assist the science teachers in the spirit of UDL and flipping can be found in this Google Doc I have started. Please comment if you can see how I can make this a better working document and share share share.......

UDL Applied and the Science Classroom:

UDL and Science and the LECTURE

There is interest in Universal Design for Learning in our district. Principals and district leaders are initiating conversations around Universal Design. This conversation is of particular interest to me as I consider that the most frequent method of delivery of information in the secondary science classroom is the lecture.

The term "universal design" was coined by the architect Ronald L. Mace to describe the concept of designing all products and the built environment to be aesthetic and usable to the greatest extent possible by everyone, regardless of their age, ability, or status in life.

According to the Centre for Applied Special Technology (CAST), “Universal Design for Learning (UDL) is a research-based framework for designing curricula—that is, educational goals, methods, materials, and assessments—that enable all individuals to gain knowledge, skills, and enthusiasm for learning. This is accomplished by simultaneously providing rich supports for learning and reducing barriers to the curriculum, while maintaining high achievement standards for all students.”

 So……back to the secondary science classroom.

Science teachers overwhelmingly agree that to successfully prepare students for the grade 12 Alberta diploma exam the only method that would seem to present itself as an option to finish the course is LECTURE. Finish the course….

 Let’s look at the course.

 In many Edmonton high schools, students are provided with the option to take the “regular” stream, or International Baccalaureate stream, or the Advanced Placement stream. Regardless of which stream they take, students have to be prepared for the Alberta Diploma exams based on the Alberta Program of Studies- So, if students are taking either of the additional programs, the amount of material required to learn is almost out of reach.

 I have worked with many creative, enthusiastic science teachers that have felt beaten down by the sheer volume of content. So how does UDL help with this?

To wrap my head around it, I began by thinking about the UDL phrase, “reducing the barriers.” What barriers are there in the secondary science class? Just off the top of my head, here are a few:

• Attendance
• Punctuality
• Completed homework
• Engagement
• Prior Knowledge
• Methods of acquiring understanding
• Demonstration of understanding
• Student readiness
• Teacher readiness
• Physical Layout of the Classroom
• Social structure

 UDL focuses on three main guidelines
1. Provide multiple means of representation
2. Provide multiple means of action and expression
3. Provide multiple means of engagement

The CAST website offers tutorials, supports and examples of these guidelines. It’s hard to argue with the philosophy.

I’ve had many discussions with secondary science teachers who also find it hard to argue with the philosophy but at the end of the day can’t see how make this work with the demands of our reality.

I’m going to offer a beginning solution. Start slow and remember that the guidelines are just guidelines meant to guide the teacher in planning for all students in an effort to reduce the number of students in the margins.

Now let’s consider the secondary science class. If the content in the lecture was included in a vodcast, rather than lecture during class, then the teacher would have time in class for multiple means of representation, action and expression, and engagement. The vodcast could be either watched at home or if students didn't have the time, then it could be watched first thing during the class. I know from experience that the amount of time it takes me to lecture is at least doubled when I lecture in class. There are distractions, announcements, punctuality issues, behavior issues etc. that reduces the amount of “usable” time for the lecture. So, to take the lecture out of the class, affords me time I thought I never had. I could use the class time for the engaging, creative ideas that have been storming in my head! I could get to know the students way faster so that during parent teacher conferences in November, I wouldn't have to struggle remembering what the name of the child was! (Consider that high school teachers in full year schools may have 200 students).

What is this magic?

It’s called the “Flipped Classroom”. Read my last post. I’m dying to try it.
