Completion of your course textbook!!
KEY IDEA: Since there is no textbook for a class like this, students will effectively write their own ‘book.’ This will be the ultimate as far as science
literacy goes, and let students create and give their voice to their learning and skill development! They will have numerous
books and online resources, and collect their work and write their book/portfolio as
they go. Include elements of global citizenship and collaborative work with other schools, around the nation and around the world. Let them look at big issues that need STEM for the development of viable solutions. Provide options for developing actual research projects.
Science is
one of a few major realms of human thought. We might claim that there are three
basic realms – Science, Religion, and Philosophy. What is the difference between these ways of
thinking? It comes down, essentially, to
the foundational way beliefs and conclusions are reached. In Religion, the foundation is faith. If one believes in an ultimate Creator or
God, that belief is based on a deeper sense of what our purpose for existence
is and how we should behave morally, and we have reached a conclusion of what
eternity and heaven and hell might be without ever really seeing these
places.
Philosophers
may argue over the existence of these places, or the existence of a God, based
on some observations of reality, but primarily on whether or not the premise of
a certain entity is logically consistent with the human experience. Some philosophers will reach a conclusion
that God exists, some will reach a conclusion that a God is inconsistent with
the way the world works, but logic dominates the way conclusions are reached.
For the
scientist, a different process of thinking is used. In essence, all three cases realms are
looking to understand our world and how things ultimately work. Science is based on what we physically
observe in our surroundings. It’s foundational ideas come about from the way
things feel to the touch, or smell like, or look like. If we don’t ‘see it with our own eyes,’ a
scientist cannot draw much of a conclusion about that particular entity or
process. Instead, observations and
measurements of a phenomenon are used to develop ideas (ultimately called
theories), and these ideas can be used to make predictions of what we would
expect to happen under certain circumstances, and those predictions need to
then be testable by others to see if they are correct. This is then what separates science from
religion and philosophy – the physical testing and observation of ideas and
predictions to determine their validity, or, in a word, experimentation.
This course
will take the reader through a process of thinking, as well as active participation and creativity. Parts may seem more like a story, and others
will be talking about multiple traditional disciplines at the same time. This will be quite different from traditional
science courses, which focus primarily on a single discipline and certain
topics, chapter by chapter from a textbook.
We’ve attempted to make this course as ‘chapterless’ as possible,
because it is our experience many students will forget about the material in an
earlier chapter because, since it had its own chapter, it must not have much to
do with the current chapter. In fact,
there is no single textbook for this course. Students will compile their own 'book' for the course!
In science, everything is related
to something else at some level, and it is that inter-connectedness we are
after. This follows from how much of
modern science research is done. Go to a
university website, and look up some research professor’s webpage. Look at their research group page. There is a good chance that a professor of
chemical engineering will have a microbiologist, a computer scientist, a
biophysicist, a chemist, and an industrial engineering student in his or her
group. Or some other funky combination
that most people would never have predicted should be working together on the
same problems. This is typical, because
actual scientists understand that to solve the complicated problems being asked
about the world, one needs knowledge in a variety of other areas of specialization. There is far too much information for any one
person to know, and we need to collaborate and share information (scientists do
this by publishing their findings in peer-reviewed journals, on web sites, in
books, at conferences, through collaborations, via personal communications, and
so on) in order to develop models and theories about why things work the way we
observe them. This premise, that many
areas of specialization are related, is our approach in this book.
We hope this approach will also
grab most readers’ attention because there will be multiple ways of thinking
about the same ideas at multiple points of the book and course. Several major concepts will work their way
into the discussion numerous times, regardless if the material is more biological
or chemical. One such concept is energy,
for example. Another such concept is the
atom. Let students use technology and modern pedagogy to present their learning in the form of essays, stories, poems/songs, music, video presentations, web platforms, debates, collaborative work with each other and with students from other schools, research, virtual visits to labs and online conversations with scientists and professors, cultural exchanges with others around the globe (global citizenship, knowledge of UN SDGs, etc.).
How it all works and fits together:
This is meant to be a two-year
course, starting in 9th grade and completing at the end of 10th
grade. Students would be team-taught, by
the same set of teachers, both years.
Teachers would rotate students every couple weeks on average, as the
material is integrated. There would be
some sort of supplemental work that is done over the summer between grades 9
and 10. There would need to be at least
7 class periods each week, so that lab work can be done. The course should be built around demos,
labs, inquiry, the inclusion of technology (PowerPoint, Internet supplements,
computer simulation, electronic sensor technology for data collection, Excel
and possibly Matlab-type software for graphing, class web page with notes and
relevant links including enrichment and advanced study materials, class blogs
or something similar for additional student feedback and posts on topics that
cannot be covered in class, conference calling with professors who can make
‘class visits,’ and so on), and group collaborative work, which is what is done
in real life jobs.
This is based on the general
structure of Chem-Phys at ETHS. It is
through multiple presentations and varied exposures to the material that
learning is more likely to take place.
Keep the notion of multiple learning styles in mind, and that each
individual should have experience with a variety of learning styles,
strategies, and techniques in order to develop higher learning skills and
ability. I personally believe that
integrating material from all the major disciplines in a coherent manner, along
with working with different teachers, will help keep students more engaged and
‘on their toes,’ and that placing a focus on how the science is used to
understand everyday life will help in student learning. This is also supported with brain and
learning research.
The material in such a course
should cover the basic, essential science from the main disciplines of physics,
chemistry, and biology, along with basic algebraic and graphical math
applications, that everyone should know.
Emphasis to everyday life and relevancy is a must, as this is what
learning and brain research shows engages students and allows for the best transfer
to long-term memory. The course wraps up
with complex, science-related issues students will need to deal with in their
lifetimes. As many of these mini-units
should be covered as time permits, and students should help decide which ones
are ‘must dos’ based on their interests.
Each mini-unit should get into the science behind the issue, and then
branch into the politics and economics of the issue, and why citizens need to
have knowledge of these issues when selecting leaders during elections.
This course should be followed up
with at least one more year of
science. Hopefully high schools will require, in this day and age, at least
three years of science for graduation.
In the 11th grade students could take a full-year, focused
course in the discipline of their choice, be it biology, chemistry, physics,
astronomy, geoscience, anatomy/physiology, or whatever else a school
offers. These could be regular/honors or
stand-alone AP courses. It is in these
full-year courses that all the details of that discipline will be
examined. The 9th-10th
grade course is meant to get into the main concepts of each discipline, as they
pertain to everyday life, and certainly numerous details for each discipline
will need to be omitted because of time restraints. We need to be honest and realistic when we
say the average person will never have a real need to know many of the smaller
ideas of a particular discipline since they are likely to never come up in the
everyday life of an average person.
Ideally, many of the main concepts
that come up in this course will have been covered in grades 6-8. Typically, it is on the second or third
exposure to an idea or concept when learning takes place. This will require close communication and
collaboration, and a well-planned vertical alignment of topics, between high
schools and middle schools. It is
essential so students get the most out of their science experience. I would go even further and state that this
should require close contact and collaboration between science and math
departments. Whenever possible, students
should get the mathematical proofs, derivations and theory in math class and
then shortly thereafter apply that math in science. This has worked wonders for students in
Chem-Phys, for example, where they get something in calculus and then apply it
in physics, and I cannot begin to tell you how many ‘A-ha’ moments I’ve seen
students have over the years…this does work.
In the end, the questions that need
to be addressed are: How do students get the best science education that is
useful to them in life? In the present
system, how much retention and learning takes place? Would this proposed science course do better? How would we know (what data and evidence
would be needed?)? I would love to do a
trial-run of this type of course, even if with just one section, to see how it
would work.
