Mission Statement
“From the very beginning of his
education, the child should experience the joy of discovery.”
― Alfred North Whitehead
― Alfred North Whitehead
When learning physics the student is
engaging in the study of natural philosophy.
The goal of the teacher is to consistently engage the student in that
study and to create an environment that will facilitate the student’s quest for
understanding. We live in a rapidly
changing world and with that change comes new opportunities to understand the
very basic principles of everyday life.
Newton’s laws apply just as significantly today as they did when he
wrote The Principia. The fact that we
can discuss them with people half a world away and that we also know of other
principles and properties that seem to make exception to these laws does not
diminish the fact that these are the principles that guide our understanding of
everyday experiences.
Galileo was able to determine the
acceleration of gravity without even the use of a stopwatch. I would challenge anyone today to match his
feat of inquiry and investigation. As we
have progressed in the availability of technology to help us measure and analyze
the universe, we have not necessarily progressed in our ability to so. Students in the classroom sometimes seem to
get even worse results when using digital tools to measure the acceleration of
gravity. Even with the significant error
of reaction time, a student using a stopwatch to time the fall of a lump of
clay can get the same level of accuracy in the measurement of the acceleration
of gravity as a student using a digital timer and photogate. With advancing technology there is sometimes
an assumption that the technology will provide the answer. In reality, we must still seek the answer and
must question our methods and analysis in order to understand the answer we
find.
The big and overriding goal of
Educational Technology in my teaching-learning environment is to provide
students with a new set of tools and methods of scientific inquiry to enhance
each student’s ability to engage in the study of physics. The addition of Educational Technology does
not change the primary goal of my physics classroom. That goal is learning through inquiry. However, Educational Technology should be a seamless
piece and greatly add to achieving that overarching goal.
Educational Technology and Inquiry
At the start of the
inquiry process the student must first generate a question or problem that they
will investigate. This may require some
basic information that the student can gain by using internet resources or
e-texts. The student can also use these
resources to help develop an experimental design. In doing this, the student will need to
identify reasonable independent and dependent variables, determine how the
variables might be changed, and in what manner might the response be
measured. Making decisions on measuring
responses will require a familiarity with the digital tools and other resources
that might be available to collect the data.
In my classroom, we have iPod, digital probeware, digital cameras, and
other technology. To be able to choose
the best tool, the student will need a complete understanding of the resource
and the variable they are measuring. There
may be occasions where multiple tools are needed. Once the data is collected, a spreadsheet can
be used to organize the data and formulas in the spreadsheet can be used to analyze
the data and produce a graph that can be used to evaluate the relationship
between the variables. In addition,
statistical software can be used to determine the significance of the
relationship and to determine if the hypothesis is supported or not supported
by the data. Finally, the students can
use a digital notebook to compile their inquiry process and to communicate the
results to others.
Learning Theory Support of
Educational Technology in Inquiry
At the basic level in the physics
classroom, objectivist theories are influential. In a very general sense on a day to day basis
providing some level of directed instruction is beneficial to student
learning. Educational technology in this
context provides students with resources, practice, and feedback that would be
supported by information processing theories.
Although an objectivist approach would seem to be supported by
the traditional science classroom, constructivist theories are predominant in a
more engaging student-centered classroom.
In an introductory physics course, students are studying phenomena that
they experience in everyday life. One of
the challenges for the physics student is to question the understanding that
they have likely already developed.
Often our everyday experience creates misconceptions and misleads us
from the simplicity of the explanation. Piaget
referred to this as schema and the development of schema occurred through
observational and experiential processes of a child. Learning (Cognitive Development) occurs
through a process of assimilation and accommodation where the existing schema
is not adequate to accommodate understanding of a situation and a new schema
must be developed (McLeod, 2009 Piaget, http://www.simplypsychology.org/piaget.html). In addition the application of Educational
technology is reinforced by the theories of Bruner. That to add educational technology and
digital resources should enhance a student’s ability to engage in discovery
learning. “How the mind works is itself dependent on the tools at its
disposal. “How the hand works”, for
example cannot be fully appreciated unless also one takes into account whether
it is equipped with a screwdriver, a pair of scissors, or a laser beam gun”
(Bruner, The Process of Education, 1977).

Dan,
ReplyDeleteAgain, let me say how glad I am to have a fellow physics teacher in class (even if my final project focus is on earth and space science, I am always looking to improve my craft as a science teacher, and for ideas for Physics!)
First, I love your opening quote, “From the very beginning of his education, the child should experience the joy of discovery.” by Alfred North Whitehead. I think this sums up science education (and education in general) very nicely!
I also like the section of your vision, "The big and overriding goal of Educational Technology in my teaching-learning environment is to provide students with a new set of tools and methods of scientific inquiry to enhance each student’s ability to engage in the study of physics. The addition of Educational Technology does not change the primary goal of my physics classroom. That goal is learning through inquiry. However, Educational Technology should be a seamless piece and greatly add to achieving that overarching goal.".
I agree that the goal of science should be for students to do inquiry, and answer the questions that arise.
Lastly, I think you did an excellent job discussing the theory, and I agree that there is room in the physics classroom for both objectivist and constructivist activities. As a teacher, it is sometimes hard for me and my students to walk away from cookie cutter labs they have done in the past and figure out how to do labs. For students, they are afraid of making mistyakes, and have a hard time getting started. I think as teachers, we need to help them by modeling what is expected. As a teacher, sometimes it is difficult to let go of the control of the cookie cutter labs.
Again, I am really looking forward to learning with you this semester!
