Websites

Introduction:

I teach high school chemistry and often will turn to the Web for activities and things I can do with the students.  There is a load of sites out there that can be useful for teachers, but some of the most useful sites are those created BY teachers for their own classes.  Here are two that I have found for chemistry classes that I find useful.

 

Periodic table activity – This site is an activity module that students are to follow with goals and outcomes clearly marked.  The activity was created by Linda Burris for an 11 grade chemistry class at Lakeland High School (link provided).  The activity is for the students to organize and design a Periodic Table without the use of the modern table in an attempt to simulate historical creation of the table.

 

Recommendations:

·        The site is very well organized provides information on many aspects of the assignment; however the rubric could be organized in a better way.  It reads now that 25% of the assignment is one thing while 25% is another, but gives little on the specifics as most rubrics do.

 

·        Links for parents, or to the teachers homepage would be useful.  The activity is wonderfully done, but provides in the end only a link to the high school webpage.  If the teacher has a homepage or index for other activities then links for these would have been good to include.

 

·        Examples of either poor projects or exemplary projects would be useful for the students.  If links for projects submitted in the past were shown so that students had some idea of what they are expected to do would be helpful.  (Though as a teacher, I know that some students will try to copy or mimic the examples closely and so this is not always the best option.)

 

Commendations:

·        The organization of the site almost perfect.  There is an introduction, an assignment, a procedure, an explanation of the evaluation and a quick conclusion. 

 

·        In addition it provides interactive links for the Periodic Table and links to provide information that helps along the way. 

 

·        It also provides a link to the school and some general information on the class and the standards that are being met with the assignment.

 

NHS Online Chemistry – The index provided here is from an online class/school.  The particular site chosen here is an index with chemistry activities that students can do online. Overall, the activities here are accessible to anyone with Internet access.  This means that they are available for teachers and students to use.  However, most of the information that could be accessed from can be done only with the permission of the teacher that organized it.  This is not a bad thing, but it does limit its usefulness for other teachers unless they are creative enough to incorporate the activities in specific ways.

 

Recommendations:

·        Many of the activities have problems that the students can try and check, but there is not much in the way of information for the students as to how they can solve the problems.  It seems the teacher is dependent on class notes or other things.  By providing information the students could use some of these activities as an exploration type activity.

 

·        Breaking the activities up into the specific units might be helpful for high school students to know when they should try each of the practice problem sections.

 

·        Assessments.  If the teacher were to attach assessments to these activities they could be used for mini quiz or drill for a quick game at the start of class.

 

Commendations:

·        The activities provided give the students opportunity to practice certain problems with the opportunity to check their answers and receive some explanations as some of the activities have a “show answer” or “solution” option.

 

·        The “view data” option that is found on many of the activities is a great and quick reference table for many different chemical properties that students would explore through the duration of the course.

 

·        The teacher seems to have organized things very well.  There is a log in option (which I do not have access to) that seems to be set up for the students and parents to communicate with the teacher.

 

Summary:  There are many teacher created sites on the Web.  Here are just two quick examples that I have located for chemistry classes and chemistry activities since that is what I teach.  To find sites for the class or subject you teach you can use some of the big search engines but might have to be creative in the keywords you use.  These sites were found after several other searches have failed to produce sites that I could use.  For these I used the keywords “teacher created websites” and some other variations that included “teacher created chemistry websites” .
