Criteria for a Quality STEMS^2 Unit

I have been thinking about my STEMS^2 unit since we first began our Learning Journeys in the summer, but I am still not sure which grade (7th or 9th) I want to develop it for.  I will probably modify one or more existing units for each grade to become STEMS^2 units but focus on one to teach and evaluate this year for my Plan B project because I think that it will be quite difficult to develop one high quality unit let alone two while we ourselves are still in the process of understanding how all of the parts of STEMS^2 can fit together and complement each other.  However, we will see how things go....

Qualities and Characteristics of a Strong STEMS^2 Unit

A strong STEMS^2 unit should include both elements from all of the STEM disciplines (Science, Technology, Engineering, and Mathematics) as well as the S^2 disciplines (Social Sciences and Sense of Place).  Each discipline does not need to be present in each lesson of the unit, but overall, each should have a prominent focus in multiple lessons so that students can see that their "subjects" are not as distinct as they often seem and can be used together towards learning objectives.  For example, if the students are learning about how plants use sunlight for energy, they will definitely be learning about the Science of the process of photosynthesis by growing plants and making observations, but will also need to use Mathematics to make comparisons and calculations and English Language Arts when reading articles about growing plants and to write their lab reports.  Including discussions about the history of agricultural practices and the current ideas about hybrids, GMOs (genetically modified organisms), and organic farming brings Social Studies into the unit.  Discussing these topics in reference to former and current practices in Hawaii and students' family practices (many students have small gardens at home or shop at farmer's markets) brings in a sense of place.  Students should be encouraged to share their own experiences and listen to others to broaden their understanding.

While there is debate about the role of National standards (Glatthorn, Carr, & Douglas, 2001), I believe that learning objectives should be aligned with the National and State Standards corresponding to the disciplines of study, such as the Next Generation Science Standards (Science and Engineering), Common Core State Standards (Mathematics and Language Arts), and NCSS National Standards for Social Studies in order make sure that the integrated unit is addressing both relevant content and practices from each discipline.  A disciplinary approach to teaching provides modeling for students of how professionals in those fields do their work and encourages students to see themselves as practitioners of that discipline rather than "students."  This along with a constructivist curriculum in which "learners construct meaning from what they experience (Glatthorn, Carr, & Douglas, 2001)," is a key component of the learning experience at ULS.

In designing the unit, assessment of students' learning must be used to gauge student understanding and progress throughout the unit, in formative assessments, as well as at the conclusion of the unit (summative assessment) to ensure that learning objectives were met.  The summative assessment does not necessarily need to be an exam or test, but should be a product that allows the student to demonstrate their understanding and mastery of the key ideas of the unit.  Offering options for key assessments throughout the unit will allow students to show what they have learned in ways that best fit their personal interests and strengths, such as making a model, composing a story, drawing a comic, or acting out a skit and encourage other students to consider different ways of explaining key concepts and ideas.

Engaging Student/Teacher Experiences

In order to provide engaging experiences for the students and teachers, the unit should be designed around just a few essential questions so as not to spread the focus too wide and allow students to integrate new knowledge and understanding into their existing framework (their sense of place) at a pace that is comfortable.  Providing a variety of learning experiences and delivery methods (demonstrations, guest speakers, lectures, inquiry investigations, peer-teaching, presentations, etc.) and assessments that address different learning styles will help to ensure that all learners needs are met.

The students and teachers involved should be wholly committed to being open to new ideas in order to fully immerse themselves in the connections between disciplines and within disciplines.  As emphasized in NGSS, cross-cutting concepts allow students to apply general information across different scientific disciplines which encourages students to recognize connections and think less in terms of separate subjects and ideas.

Unit Length

Glatthorn, Boschee, Whitehead, and Boschee (2005) define a unit as, "an organized set of related learning experiences offered as part of a course of study, usually lasting from one to three weeks" that is often "organized around a single, overarching concept (p. 18)."  I think that the STEMS^2 unit that I develop will need to be closer to three weeks or perhaps even longer to fully immerse my students in the material and include a field experience such as a Learning Journey and/or visits from professionals in the disciplines.  The length of the unit is not as important as the depth into which we explore and discuss the key ideas, so it will likely depend on the specific topic of the unit and the learning objectives that are chosen.  If growing plants or taking observations over a long period of time is involved, the unit may span a couple of months, but be integrated into a larger unit that has several subunits to accommodate the amount of time needed for a longitudinal study.

Head above water "snorkeling"

20151011

With a lot on my "plate" and mind lately, I was fortunate to have a chance to slow down and smell the fresh sea breezes and spend some time exploring the expansive Ahua Reef near "Dog Beach" at Hickham AFB.

Since my 9th graders are close to a week away from finishing our Physical Oceanography unit on mapping, here is a more accurate location (also known as an absolute location rather than a relative location).

Spherical Coordinates: 21.315231, -157.958262

In Decimal Degrees: 21.31531°N, 157.958262°W

In Degrees, Minutes, Seconds: 21°18'55" N, 157°57'30" W

*Here is a nifty site that converts from decimal degrees to degrees, minutes, seconds if you don't have a teacher like me that makes my students do the actual calculations themselves to understand how each degree is broken down into minutes and seconds ;)


This excursion was actually requested by a friend of mine whose boyfriend has recently become obsessed with collecting shells.  It also required my boyfriend to tag along so that we could get on base, so the four of us headed out around 10:00 a.m.

The water is very shallow and somewhat murky making visibility poor.  Even half a mile out from the shore, I could stand on the sandy/silty bottom and the water was only up to my chest.  First exciting sighting was black brittle stars, Class Ophiuroidea.



There were also many black collector urchins that I think are called hawa'e maoli.  Here is one of my favorite articles about them from 2009 in the Star Advertiser.  Susan Scott's column always has interesting ocean-related information. http://www.staradvertiser.com/columnists/20110214_Sea_urchins_the_perfect_janitors_to_keep_Kaneohe_coral_clean.html?id=116145179


Panoramic view from the water...  Diamond head is to the far right of the photo, a very faint outline, Nanakuli mountains on the far left.



There wasn't much besides low, dead coral beds in the middle, with the occasional footlong sea cucumber, so I headed west towards the higher reef where fishermen were standing knee deep in the water. http://www.waikikiaquarium.org/experience/animal-guide/invertebrates/echinoderms/sea-cucumbers/



Here in the more lively reef, there were beautiful but bleached coral heads which means they had recently either lost their zooxanthellae or expelled them for some reason, possibly in response to higher ocean temperatures and increased photosynthesis (see some informative readings below).



Lots more pink and pale green rock boring sea urchins and marine sponges were embedded in nooks and crannies in the reef.  http://www.waikikiaquarium.org/experience/animal-guide/invertebrates/echinoderms/rock-boring-urchin/


Having some time to myself (I was not snorkeling due to having scratched by eye the day before) I was able to practice my "kilo" while at the same time testing my memory of marine invertebrates. Teaching Marine Science has greatly increased my interest in the live versions of the organisms whose former homes and skeletons (shells and exoskeletons) I have collected on shorelines since I was little.  Matching the whole organisms to their spines, shells, and fragments is a kind of inquiry process that I really enjoy, it's like detective work.  Recalling common names, scientific names, classifications, and learning Hawaiian names is also fascinating to me.  I took pictures of everything I could recognize as well as what I could not to take back with me to help tell my stories.

Next I spotted something very unmistakably pink near a part of the reef that was exposed.  "Never turn your back to the ocean" is very wise advice, so it was difficult to get close enough without turning my back or facing the oncoming waves in the knee deep water.


The pink splotches turned out to be coral!  Cauliflower coral, also known as ko'a and Pocillopora meandrina http://www.waikikiaquarium.org/experience/animal-guide/invertebrates/coral/cauliflower-coral/















While taking the long trek back to shore, I wished that my students could come out to see this, or at least something similar.  56 students at one time would be impossible.  28 with several additional chaperones would be manageable if we were allowed to go this deep in the water.  Place-based learning is definitely more difficult to accomplish when safety is a concern.  The OPIHI project would definitely help facilitate a shoreline field study in the Spring, so I guess that's my next application!
