How to record experiments in lab and science notebooks

Posted by Rory on November 8th, 2010 @ 8:08 pm

In the beginning there was paper

Traditionally, science experiments have been recorded with paper lab notebooks.  There are hundreds of guides on the web, like this one, with advice on how to prepare and keep a paper lab notebook.  Most scientists in pharmaceutical and biotech companies, however, have switched to electronic lab notebooks, and scientists in universities are gradually beginning to adopt electronic lab notebooks as well.

Science Buddies

When we brought out the first version of the eCAT electronic lab notebook in 2009, we wanted students in schools to be able to have access to an electronic lab notebook so that they, too, would be able to benefit from the convenience and increased efficiency that electronic lab notebooks bring.   To do that we established a cooperative relationship with Science Buddies.  Science Buddies is a nonprofit organization that provides “free science fair ideas, answers and tools for serious students”.

eCAT for K1 – K12 students

We wrote a brief overview of how to use eCAT to document an experiment, which appears on the Science Buddies website.  We also set up a dedicated instance of eCAT for K1 – K12 students to use in documenting their experiments, and we made that available through Science Buddies.  You can sign up for an account here.  You get the same functionality as with the normal Personal version of eCAT, and like the normal Personal version, the Science Buddies version of eCAT is free.

eCAT for teaching

We have also received a lot of interest in eCAT from K1 – K12  science teachers.  So, we recently put together a video on using eCAT to teach science classes like biology and chemistry.

To give you an idea of what an experiment looks like in eCAT, here’s an example

How to teach biology, chemistry or physics with the electronic lab notebook eCAT

Posted by Rory on September 27th, 2010 @ 11:53 am

People often associate electronic lab notebooks with research.  That’s not surprising since that’s mostly what they’re used for!  But there is also  growing interest in using electronic lab notebooks as teaching tools, in both  universities and secondary schools.  For example, Dave Lunt at the University of Hull has an excellent presentation on using ELNs for student research monitoring.  In this post I’m going to go through setting up eCAT for teaching a class in science subjects like biology, chemistry and physics.  We’ve made a video that covers the same ground, so if you’d rather watch the video, here it is!

The scenario

To make it practical, let’s use a real  scenario.  Say you’re teaching Biology 101.  You’ve got 20 students enrolled in the autumn semester.  As part of the course the students will be doing some exercises and also carrying out some experiments.  Some of these will involve group work, and some will be individual work, for assessment.  You want to use the electronic lab notebook as an environment where students can document experiments and carry out exercises, and you can see their work and comment on it.  You want some of the students’ work to be private — only you and each student have access to it.  And you want some of the work to be accessible more widely so that groups of students can work together.

Setting up eCAT

You can use either of the group versions of eCAT — Team Hosted, which Axiope hosts on our servers, or Install, which is installed on your server.  To get started you login as admin.

Both versions of eCAT come preloaded with a Projects folder and a Users folder. You’ll be using both of these folders.  Here a a few screenshots of eCAT illustrating some of the actions described below:

  1. To get started, click on the admin tab and then Users, and set up user accounts for the students who will be taking the class this semester/term.  When you do this each user will automatically get a home folder with their name; these will appear under the Users section of the record tree.
  2. When each user logs in, they can create whatever they want in their home folder and only they (and you the admin) can see it.
  3. Staying in the admin section, click on Groups.
  4. Create an All Users group, and add every user to this group.
  5. Create four working groups (we’ll call them Group A, Group B, Group C and Group D) with five students each; these are the groups that will be working together on experiments.
  6. Now go back to the record tree and, under Projects, create a new folder for Group A. To do this, click on “Create New” and then select “Create as Owner” after selecting the Folder class type. Call this folder, “Group A Materials”.
  7. Click on advanced Sharing, and give Group A view, edit, append and download permissions.
  8. Then create a child record under the Group A Materials folder – an Experiment.  But this time click on “Create as Parent”. Then also create a Document record in the same way.
  9. Do the same to create Materials folders and Experiment and Document records for Groups B, C and D.
  10. Now go back to the Record Tree, click  the Projects folder, and create a child folder called ‘Course materials’.
  11. Use this folder to place materials you want  people to look at.  For example, you may want to create a set of instructions for using eCAT during the course.  You can do this by creating a new document in this Course Materials folder.  You also can import pre-existing documents, spreadsheets and images, for example you could import an ‘Initial Materials’ document. Give all groups view permission for this folder so that they can see all the course work.

Using eCAT

It’s that simple!   eCATis now  set up and ready to go.  How you use it is of course up to you.  But here are some simple examples of the kinds of things you can do with the set up you now have in place.

  1. Document experiments.  Each individual student and each group can use the Experiment record that has been set up for the group to document their first experiment.  As shown below, the Experiment record already is divided into fields for Method, Procedure, Objective, Results, Discussion, Conclusion and Comments.  For the Group records, you may want to set up some standard procedures (see below for more on this) to ensure that things are well organized and recorded.  For example, you could have a rule that each time a member of a group makes an entry in a Group record they should place their initials by the entry.
  2. Comment on experiments.  As admin, you have edit permission on all the records that have been created.  So, you can comment on the experiments  the groups and the individuals carry out.  Just do this in the Comments field, and it will be clear that the comment has been made by you.
  3. Create new records.  You, individual students and groups can create new records, as needed, as the semester proceeds. You/they can create new experiment and document records.  You/they can also create other kinds of records from the more than 20 preexisting templates that eCAT comes with.  And both you and they can also create records of your own design using eCAT’s class creator function.
  4. Communicate.  You and the students can use eCAT to communicate about Biology 101.  You can send messages about assignments, deadlines, etc., and you can also create tasks.  In both cases these can be addressed to individuals or to groups, and in both cases you can include links to eCAT records, so for example you could send a message to Group A about a particular experiment they are working on with a note that you have made a comment on it, and you can link to the experiment in the message.

Instructing the class on how to use eCAT

At the start of the course you’ll want to introduce eCAT to the class.  There are various ways to do that, and you’ll probably want to use some combination of:

  1. Having everyone view the Getting started with eCAT video, on their own and/or as a class so that there is an opportunity for questions and discussion.
  2. Preparing some specific instructions covering how you have set eCAT up, how you plan to use it and standard procedures to follow, and making these available, e.g. in a powerpoint presentation (which can be attached to an eCAT record) or a document placed in eCAT.
  3. A demo of eCAT.

Getting eCAT ready for reuse next semester

Your eCAT  licenses are reusable.  So if you have 25 licenses, and a class of 20 – 25 students, you can keep reusing the licenses each time you have a new group of students.  So, when the semester is finished, you simply delete from the User list the students who have just finished the course, freeing up the licenses for the students in next semester’s course or another course.

Try for yourself

Now you’ve seen how it works; why not try eCAT yourself?  You can sign up for a 30 day free trial here.
