The Perfect Match

(Volume 86, Issue 8)

By Julie Reynolds

A lesson that focuses on the intricate co-evolution of flowers with their pollinators is one way to help students learn the delicate balance in nature and help ensure that our actions do not upset this balance. In this lesson students use the engineering design process to engineer a flower that is a perfect model for its chosen pollinator. Next, they construct an explanation of the coevolution process that occurs between flowers and their pollinators. The lesson addresses HS-LS4-4 Biological Evolution: Unity and Diversity from NGSS and covers Common Core Writing Standard CCSS.ELA-LITERACY.WHST.11-12.1.B. The various activities in this lesson allow for individual work, whole class discussion, and group work consisting of groups of 2-3 students. This lesson is a great way to use plants as the model for teaching evolutionary concepts in a biology class, can be done in conjunction with other lessons on floral reproductive anatomy, or as a stand-alone lesson as long as attention is given to new vocabulary. At the conclusion of this lesson, students will have a model of a flower that they will use as an aid in constructing an argument on the coevolution of flowers and their pollinators.

Investigating Urban Trees

(Volume 86, Issue 8)

By James Carrigan, Alec Bodzin, Thomas Hammond, Scott Rutzmoser, Kate Popejoy, and William Farina

Mobile geospatial technologies enable high school students to engage in authentic scientific data collection and analysis that promote spatial-thinking and reasoning skills, as well as problem-solving in a school’s local environment. We developed and implemented an Ecological Services investigation aligned to the Next Generation Science Standards in an urban high school with a large population of economically disadvantaged students. The investigation includes local field data collection with mobile devices and classroom data analysis using a freely available Web Geographic Information System or GIS. The field investigation focuses on observation skills and uses a dichotomous key to identify local tree genus and species. Student data analysis focuses on spatial patterns of tree species surrounding the school and exploration of the geospatial relationship between percent tree canopy cover and crime statistics in the city. Students were actively engaged with using geospatial technologies to investigate relevant socio-environmental issues in their community. Students thought critically about the costs and benefits associated with urban trees and proposed changes to their community that will have a positive impact on their local natural and built environment.

Ed News: Should Teachers Choose Their Own PD?

By Kate Falk

Posted on 2019-03-29

News Roundup banner

This week in education news, new study finds novice teachers are more likely to end up in schools with fewer veteran co-workers; Wyoming Ed Board disagrees on the direction of the state’s proposed computer science standards; students see more success in K-12 when they tackle STEM concepts in early grades; district leaders say choice in professional development is good, but high-quality, standards-based options are necessary; researchers say the teacher shortage problem is worse than originally thought; Maryland high school graduation requirement tied to a demanding new science test; Utah parents and residents criticize proposed science standards; science teachers need to make clear to student that despite all we’ve learned, our universe remains ever mysterious; and the 100Kin10 network announced it has put more than 68,000 STEM educators into K-12 classrooms.

Study: Novice Teachers Often Face Tougher Loads Than Veteran Colleagues

Despite being less experienced in the field, newer teachers — especially those with less than two years under their belts — are often placed in more instructionally demanding classrooms, which have more disadvantaged and low-achieving students, than their veteran colleagues, a recent study finds. Read the article featured in Education DIVE.

Wyoming Ed Board Disagrees on Computer Science Standards

Discord over the direction of the state’s proposed computer science standards left the State Board of Education in a stalemate. Two motions — one to move forward with the draft standards and one to send the standards back to the Wyoming Department of Education for retooling — failed last week, leaving action on the standards in limbo.

STEM Education Myths in Early Grades

Consider these ideas: Some kids are STEM kids and some aren’t. Students need to master science and math basics before moving on to STEM concepts. STEM focuses on future jobs, so educators should concentrate instruction in middle and high school. Wrong, wrong and wrong, say the experts. In fact, such myths contribute to many students’ STEM struggles. Read the article featured in District Administration.

Should Teachers Choose Their Own PD?

The Trump administration, as part of its fiscal year 2020 budget proposal for the U.S. Department of Education, wants to fund and evaluate a demonstration of “teacher-driven” professional development (PD). Read the article featured in Education DIVE.

Are Teacher Shortages Worse Than We Thought?

The teacher shortage is “worse than we thought,” researchers conclude in a new analysis of federal data. The study, published by the union-backed think tank Economic Policy Institute, argues that when indicators of teacher quality are considered—like experience, certification, and training—the teacher shortage is even more acute than previously estimated. This hits high-poverty schools the hardest, the study’s authors say. Read the article featured in Education Week.

Demanding New Science Test is Teed Up as a Maryland Graduation Requirement

The rollout of a high school graduation requirement tied to a demanding new science test could be delayed for at least two more years, following a preliminary vote of the Maryland State School Board on Tuesday. The board voted to change a regulation that would have made passing the Next Generation Science Assessment a requirement to obtain a diploma beginning in 2020.

Chrome-Plated Activities

By Gabe Kraljevic

Posted on 2019-03-29

Do you have any suggestions on how to use Chromebooks in middle school for more than just watching videos and reviewing material?
—A., Indiana

 

The real power of computer technology for a science classroom is in graphics, communication, calculations, creativity, and interactivity. Simulations like those at https://phet.colorado.edu/ allow you to augment lessons that would otherwise be impossible to perform in class. They differ from videos in that the students can actively participate by manipulating variables.

An excellent teaching tool is for students to script, record, and edit their own videos which can take the form of mini-documentaries, animations, public service announcements, science shows, music videos, and so on. There are many free video-editing options available.
Communicate electronically or via print by creating presentations, wikis, blogs, brochures, posters, and comics. A very powerful way to learn something is to teach, so buddy up with a lower grade and have students create picture books or graphic novels for them.

There are many citizen science initiatives in which your class can participate and a wealth of online data that your class can download for their studies. There are online telescopes and real-time webcams that you can access to bring astronomy, ecology, and biology right to your students’ devices. You can make science investigations real and exciting by collaborating with classrooms almost anywhere in the world.

Chromebooks can also be used as scientific devices and data-loggers by attaching probes, digital microscopes, and cameras.

Hope this helps!
