This is not your father’s homework assignment.

Homework is evil. All homework. It’s a pile of worksheets; pointless, drill-and-kill busywork that overloads students brains, frustrates (or bores) them to tears, reinforces the practice of incorrect algorithms, destroys every creative cell in students’ bodies, and takes away from valuable playtime or family time. And it should never, ever be graded.

That’s the message sent by many who are trying to fix whatever’s wrong with education. I don’t buy it.

Sniff-O-Meter

Our school is on an AB block schedule.  I see students at most 3 days a week (when we have a full week of school), so more often twice a week; sometimes 4 times in 2 weeks, and sometimes 6-7 days pass without meeting as a class when we have long weekends.  (Yes, I use electronic communication as much as possible, considering 20-25% or my students have neither an Internet connection in their homes nor a smartphone). To that end, my teacher-gut tells me that students who have deeper conceptual understandings and own their skills are the students who have stayed connected to their learning. I’ve become a fan of a few types of assignments to help students stay connected.  Some are most specifically, homework. Other assignments are directly connected to an upcoming inquiry or project lab. Other work is investigative, calculation practice, synthesis, or preparation for discussion.  Outlined below are some general types of “homework” students may expect to best support them as they learn science.

Title IX in Engineering?

The misinterpretation of Title IX with respect to student gender quotas in university engineering departments on Joanne Jacobs’ blog yesterday received a bit of discussion Saturday on Twitter. Jason said, in reference to the post,

A little later, this tweet popped into the conversation.

Scavenging For Science

Many years ago, I needed something engaging for AP Chemistry students once their exam was over.  I found a scavenger hunt, hard copy as this was the olden days, handed out by the late Dr. Cliff Schrader at a conference.  I’m forever grateful to Cliff for so many things he gave out freely to anyone who asked.  Among so many other things, he taught me to share.

I reworked the list a little to reflect some things my students knew or in which they had shown interest.  The first few years, the kids worked in groups and competed to see which group could collect the most items the most quickly.

Will I “Flip” my Classroom? 2012 edition

Truth is, I already did. Years ago.

About 2 years into my career, I figured out that if students arrived in class already knowing something about the day’s learning, they took away a deeper, more satisfying, understanding. We were able to use class time differently, in ways that helped us learn more authentically.

I did not need standardized tests, value-added evaluations, or clever new names for the method to figure this out, by the way.

Adoption, 2012 style

I’ve worked in 5 districts in 23 years.  Our current adoption will be my 4th experience. The availability of electronic delivery and open source materials have added interesting options to our decision-making. First, I present lists and links to content, including sources for inquiry and engineering design resources. I’ve saved my thoughts on devices until the end.

Please comment including any other resources you’d consider if you were us.  Also, please comment on individual resources if you have experience or thoughts that might help us make a decision.  This list does not include all of the traditional hard-copy textbooks and support materials we’ve been sent.  I don’t want this post to take a year to read.

Writing and the Lab Report

Oregon requires students to complete an inquiry work sample (here’s the one we will use this year) at some time during high school.  Our classes function on an inquiry basis at some level almost daily.  I’ve played with many strategies to help students write about their work in a manner that facilitates their learning while documenting their work in a manner that survives the scrutiny of a scientific peer review.

Most recently, I’ve incorporated the work began with Linda Christensen (from Lewis and Clark) and the Oregon Writing Project. Freshmen begin keeping all lab and inquiry work in a bound theme book, AKA fondly as “my lab book.” My vision for the appearance of student lab books has morphed over the years.  Some things change very little, though, because good science is good science and good science writing is good science writing. At my current school, I’m blessed with like-minded colleagues who have helped me refine my vision as it is shared in this post. Here’s our current plan…..

First Day 2011

Beginning my 23rd year in the classroom, I still get a bit nervous that everything will go well. I walk through each class at least 20 times in my head and tweak things until the last minute.  Classes begin on September 6.  Every day except for 2 until them, I have meetings or some random duty, or prep work scheduled.

My goals for the school year are to bring more relevance to our learning, better help each student reach his/her potential, and to do so without working 23 hours a day and all weekend. This partly stems from the stress last year of finishing the dissertation while starting a new job.  I was either teaching, grading, planning, writing, crunching data, moving, or sleeping, in that order. (I ate while working on something. Couldn’t figure out how to work in my sleep.) I’d like my classes and my life to move at a pace that allows time for reflection and revising and laughing at least a little.  And I never, ever want my desk to look like this again:


Here’s my first day so far:

Learning Targets:
1. Science: Remember that? (A little science on the first day never hurt.)
2. Learn roles and protocols for group work (because 9th graders usually don’t know what to do in a group.)
3. Explain what we will learn this year, why and how we will learn it.

Attention Elementary Teachers:

I’m analyzing data from pre-service elementary science teachers who are working on an inquiry learning project.  I’m a bit surprised with the results.  Before I share, I’d like to hear from some elementary teachers about your current teaching of science and your teacher preparation program.  What do you feel you teach really well in science?  Where and how did you learn to do this well?  In what areas do you most want to grow?

I can’t wait for your comments.  In the meantime, I’m back to data analysis.

Charlotte molted again

Charlotte's molts 11-26-08 and 1-29-09

Charlotte's molts 11-26-08 and 1-29-09

Charlotte joined our classrom in August as a gift from a school board member.  She is a Red-Rumped Tarantula, Brachypelma  vagans.  Although the species is native to Mexico, we’ve seen them throughout Belize. We were told she was 3.5 years old when she came to us and had just molted. We were told, and read, that she should be fed several crickets about once a week and that she would molt twice a year. I was surprised to come in the day after Thanksgiving to find that she had molted sometime during the past 48 hours.  I retrieved the molt (top) and placed it in a specimen jar.

Six crickets began to disappear from her habitat within hours of delivery.  I started to worry that perhaps she needed more to eat and began feeding 8 crickets and a few mealworms, then 12 crickets……

I came in Thursday morning to find Charlotte lying flat on her back near her burrow.  Occasionally, she moved a leg but appeared to be dying – exactly as all I had read about molting described. I removed all the crickets I had just given her, no easy task,  and we checked on her from time to time.  By 1:00 she had completely emerged from her old exoskeleton (bottom) and was resting back in her burrow.

I think she’s growing.
