ACCESS Earth

Imagine being in a group of teachers venturing out onto a misty salt marsh one gray day in July, seabirds mysteriously swirling through fog above the salt hay and ocean waves crashing in the distance. We were learning research techniques used by Professors at the University of Southern Maine, which is located in Portland, Maine, to study the affects of sea level rise on the salt marsh environment. The science was incredible and transferable to activities that could be performed back at school. We were also brainstorming and envisioning ways to make these field activities accessible to students with mobility, visual, and hearing impediments. If you had returned the following summer you would have seen roughly twenty students and teachers excitedly working together to pull a five-meter core sample from the marsh using a vibracore. Only after a while would you realize that among the close-knit group, there is a young woman on crutches, there are two people in wheelchairs, and there is a sign language interpreter for a student with a hearing impairment. The vision of the previous summer had been fulfilled. Imagine returning a third year to work with students who have reading and written language disabilities, dyslexia, autism, and behavioral or attention difficulties.

As an earth science teacher challenged by an increasing number of students with disabilities in the regular classroom, I was looking for teaching strategies, to ensure the forward progress of all learners, and the latest earth science concepts, to incorporate into my curriculum. The Access Earth Summer Institute provided an experience that opened new pathways for teaching and relating to my students. The Institute was part of a project sponsored by the National Aeronautics and Space Administration (NASA) and the National Science Foundation (NSF), designed to effect long term changes in the number of people with disabilities pursuing studies in the geosciences (0.2% of graduates in 1995), and in the methods, materials, and curricula used in high school earth science classes. One goal of the project was to gain deeper understanding of earth science by participating in field and laboratory activities that incorporate earth system science concepts. This was achieved by participating in the ongoing research of professors at USM, studying the effects of sea level rise on the salt marsh and the land use changes in a beach-estuarine system at the Wells National Estuarine Research Reserve located in Wells, Maine. Students and teachers worked together in the field, and in the science and GIS (Geographic Information Systems, a computer mapping technique used for storing information in layers) computer labs at USM. Together we learned to develop adaptations appropriate for learners with special needs for field and laboratory activities, including computer based assistive technologies.

During the institute, teachers, staff, and students got to know each other and learned about the salt marsh as a model system for studying the effects of sea level rise on soils, plant ecology, water quality, and land use. We learned about GPS (Global Positioning Systems), remote sensing, and GIS for data presentation. We also learned how to accommodate the needs of students with disabilities through instruction from the Access Earth staff on assistive technologies, by searching for information on websites, and through personal conversations with the students. This article describes strategies learned from the Institute that I was able to apply in my classroom.

Developing an Awareness of People with Disabilities: Person First Language

Through instruction and personal conversations with students I learned to focus on the student before the disability. I became aware of the importance of using “person first” language for example, “students with disabilities” rather than “disabled students,” and to avoid statements that qualify the person with a disability.

Know Your Students

You must give students self-confidence, enabling them to trust you enough to communicate their needs and advocate for themselves. Before you can make a lesson accessible, you need to understand the nature of the student’s disability. We learned from the students at Access Earth that they want to be asked about their disabilities and in many cases, they can provide the teacher with the best suggestions for how the teacher can help. In order to give that self-confidence, a teacher must truly believe in these students and their abilities to participate, contribute, and have profound insight. Making sure students with disabilities are included in all aspects of the class provides an atmosphere that emanates respect and dignity, and acknowledges that students with disabilities have equal potential to learn and contribute to the class. I encourage all students to advocate for their needs and to give me feedback on how I am doing at meeting them. At the beginning of a new class I have all students fill out a “Getting to Know You” sheet and I ask specifically how I can help them learn. I follow up the questionnaire by having a one on one conversation with each student. Important feedback from the student can be given in writing or through conversation that follows, focusing on building strengths and expanding our relationships.

Consider How You Teach

Along with understanding my students and the nature of their disabilities, I had to take a closer look at the way I teach them and ask, “How are students perceiving me? What does my teaching look like or sound like to them? Am I reaching them or is it all going by in a blur?” I became aware of this during a skit put on by the students at the workshop, to show teachers what learning can be like for students with learning disabilities. The students presented the teachers with an article that had specific words blacked out. They asked us to read the article and put it into our own words. We were only given a fraction of the amount of time it would have taken to read the article. Immediately we experienced the frustration they encounter every day at school. Asking your students to enact similar skits about their learning experiences may provide you with more insight on how to empower them.

This experience made me realize how much I need to pay attention to how I present material. I have learned to monitor the class’ understanding more frequently and adjust the pace at which I teach accordingly. By doing this I stay more in touch with the students’ learning and we move forward on a solid foundation.

I teach in shorter segments and vary the classroom activities to involve more students in role-playing, skits, and poster presentations, so that the learning takes on more of a story format. This active participation gives students ownership in the class and encourages positive contributions.

Models are great hands on activities. By providing visual, auditory, and tactile activities, all students have a better chance for learning. Repetition in different formats and forms of media helps all learners. Before embarking on the plant and soil studies at the salt marsh, teachers made a poster of the cross section of the high and low marsh areas. Students were given samples of the different plants and had to physically place them where they belonged on the poster. The teachers then demonstrated sea level rise using a large piece of blue plastic wrap. The students could see how the sea level rise could affect the distribution of plant types on the different marsh areas. Students and teachers alike enjoyed the novelty of the blue rising and the tactile placement of actual plants. Such activities are great as students are experiencing the content through different senses, which enhances learning.

We learned to help students with organization of material by having them use computer programs such as Inspiration to create concept maps and models of systems. You can assist students with reading difficulties by providing books on tape and use of text to speech programs such as Kurzweil and Quick Light.

In addition to providing a multi sensory approach to instruction, I also offer multiple ways for students to demonstrate comprehension. Besides using a traditional test or report for assessment, students may demonstrate their knowledge in other formats such as a computer presentation or a 3D model. This is important because different learners have different needs. We should be adapting to the way students can most easily demonstrate their understanding of the lesson.

Accommodations for students with mobility impairments, visual impairments, and hearing impairments can be found on the Access Earth Web Site and an Earth Systems Idea Book with activities that are accessible to all will soon be on the Internet.

Finally, a great strategy is to stimulate students’ awareness of the local environment by involving them in a research project that incorporates real world problems and the local community. Find a local problem and use the Earth Systems approach. Not only does this offer an investigative context for learning, but it also provides an alternative social setting that can open up students’ minds to learning in new ways and unleashing their potentials. Involving students in research projects encourages them to develop investigative and problem solving skills. It gives them the opportunity to see how scientists view the world and some experience in the approaching of problems in a logical, systematic fashion, working as a team. It also gives them the opportunity to participate and contribute, which bolsters self-esteem and confidence. Introducing a research setting allows for varied forms of student interaction. Students are teammates as well as co-adventurers. In this type of setting, students reveal hidden parts of themselves, for some they are now in a setting where they can soar.
