California’s latest trend -- not teaching science

Silicon Valley is going to be in trouble in ten years -- or, at least, more trouble than it's currently in. While they may have enough people writing English and able to give correct change for cash, they may have a staggering lack of scientists. According to a recent study by WestED, only 10 percent of students regularly receive quality science education -- something that has principals concerned, and something that should have parents concerned as well.
The numbers are not pleasant to look at. WestEd found that 40 percent of elementary school teachers spend less than an hour each week teaching science, and those who did teach it often had trouble managing time for adequate lessons. Personal education was another problem. According to the interviews, only 1/3 of them felt they were actually prepared to teach science subjects. Eighty-five percent said they hadn't received any kind of science training or continuing education in science in the past three years. Many teachers said that they didn't have funds or supplies to teach science even when they had the time and training.
Middle Schools play catch up?
There are several issues that compound the problem. California has recommended rules governing how much time teachers should spend on language arts and math. Other subjects, including science, aren't given any guidelines like this. In addition, some districts don't really push to teach science until students reach middle school, since science isn't covered on standardized tests in the elementary grades. This is a grave mistake, because much of the foundation for a good science education and the development of a healthy curiosity can be built in the early grades.
While educators and others are working to address the issue, in the short term there's very little science in the California education system.

Videos for teachers: new chapters of "Chemistry Now"

The National Science Foundation (NSF)is teaming up with NBC Learn to launch a weekly series of online videos about the science of common objects and the changes they undergo every day and the chemists who study these things.

The videos, called "Chemistry Now" is a series of 32 lessons break down the chemistry behind things like as cheeseburgers, chocolate, plastics and soap-- and that's just for the first series.  Also featured on the NSF site this week is a video called 'Chemistry of Ocean Clean-Up,' which comes out on the one year anniversary of BP's capping well that created the Gulf of Mexico oil spill.  Focused lesson plans for this week are called "Top 10 Big Questions in Chemistry."

This weekly series will build on the 23 original "Chemistry Now" videos that were released during the spring school semester this year.  Best of all, it's available at no cost on the NBC Learn and nsf.gov websites and the NSTA blog.

Desperately Seeking Science Education

Are in-school "special programs" starting to replace science education in this age of teacher and education cutbacks? A rash of "just in time for schol to start" articles about science education suggests that teachers and schools are turning to special programs to help interest kids in science and teach them some basic concepts. And it's no wonder -- if a recent study in California is any indication, students are getting less than 40 hours of science education for the entire school year!

Quantum Camp (is one of a number of programs designed to supplement this lack by bringing science education by science teachers into the classroom. They bridge the gap between education and entertainment and spark curiosity with interesting experiments and even by incorporating music and storytelling.


But -- as an ex-teacher, I have to ask just how effective this is. While it's better than nothing (20 hours per year), 30 minutes of excitement does not replace five hours of drilling and practice. While kids will become engaged with experiments like mentos and cokes, will they remember and understand the reasons why this process happened -- and will they be able to apply these scientific principles in the future. Can someone educated by science entertainment go beyond the simple and start asking the complex questions and making the sophisticated connections needed for good science research?
I have already seen how kids use videos on message boards to "make" a point without really understanding the background of the question and the material. It's a troubling idea when you consider the reports that we're falling behind on science education.
