PERIODIC TRENDSPERIODIC TRENDS

My Lesson and Myself My name is Beverly McElroy, and I teach

Chemistry at Calexico High School. My e-mail is [email protected] if you wish to contact me.

In this lesson, students are guided toward discovery of the logical organization of the periodic table and the trends present in families and periods.

My Expectations Through this project, I expected to learn new skills for adding

challenging and interactive components to my Chemistry lessons. I expected to be overwhelmed with the complexities of this class because I have only very basic computer skills.

My experience with the block schedule has taught me that 86 minutes of Chemistry can quickly become tedious without extensive hands-on interaction. I was interested in developing technology and multimedia based activities for engaging students, but needed more training and better skills myself.

I feel this program has given me the skills and confidence to create better technology/multimedia lesson plans. Along with my students, I am experiencing mistakes and identifying areas for improvement.

My Realities I learned how to construct a lesson plan using

hyperlinks to files as well as the internet. I learned how to use Excel to construct performance

charts for students. I learned how to better construct a lesson so that

standards are explicit and focused for students. I learned how to construct a web-quest, however

simple it might have been.

Successes The largest success was the engagement of all students on the

assignment. Actual learning varied greatly from student to student, but every student was absorbed in the lesson.

Also successful was the degree to which students gained an understanding of the periodic table without teacher instruction. Ownership bred success.

Students really seemed to enjoy demonstrating their knowledge using power point. Many students had never used power point and enjoyed learning how to make a presentation with pertinent images.

Providing the rubric ahead of time kept students focused on minimum requirements for success.

Shortcomings The greatest shortcoming was a poor estimation

of time that students would need to complete the assignment.

Secondly, students needed more precise directions on how many elements they needed to explore.

Student involvement was high, but so was the confusion. With all the information available, limit the number of properties they are to consider.

Lesson Plan Revisions To improve the lesson, I decided to focus only on standard 1c.

The inclusion of 1a-c standards made the lesson too broad. Also, I will eliminate the essay comparing student’s findings

with teacher instruction. Only one essay analyzing their independent findings is necessary.

I will allow 2 days for the internet webquest. Power Point presentations will be created by individuals, not

by groups. This change was made after beginning the lesson. I will instruct students on the use of Power Point prior to the

webquest. Students who finish earlier can then start constructing their power point slides.

Synthesis Slide Through this experience, I feel I am better able to construct

quality lessons focused on standards, which incorporate a hands-on/interactive aspect for students other than the normal labs. I learned that students “buy into” the work more if it includes computers and technology. I also noticed how much more the students enjoyed the work as opposed to just using the textbook- lecture-lab format. Whenever appropriate, I intend to use technology to enhance student achievement of standards. The Post test demonstrated learning, while the Webquest and Power Point provided an engaging avenue for achievement of that goal.
