Welcome to Ladderan's blog!


We are thrilled to share our story with you. 

Various reasons have been attributed to the lack of learning in hands-on labs. One factor is high cognitive load as students are given too much information all at once. Therefore, students tend to concentrate solely on acquiring procedural knowledge to get the results/product. Another factor is performing experiments without having learned the theory first. Understanding related theories and concepts is key if students are to construct knowledge from experiments. Hands-on labs are also expensive to operate in terms of facilities, resources, and staff time. 

There has been increased interest in developing online labs across a variety of domains and educational disciplines to address some of the gaps with hands-on labs. Besides being less expensive, other advantages of online/virtual labs include presenting unobservable phenomena, providing a safe environment for performing experiments, and conducting more experiments in a simpler and more timely manner. The recent pandemic has further demonstrated the need for effective online labs. 

Designed by experts in lab-based learning and online learning, Ladderane offers two main purposes. 

First, it is designed to help students understand the rationale for experimental procedures and reflect on what they are doing. Ladderane's user friendly interface, combined with opportunity to add reflective questions, and videos to explain theories or procedures, provides an opportunity for students to understand the why and why of experiments without being overloaded. Ladderane incorporates research such as multimedia design principles and cognitive load theory to help instructors develop effective online experiments. We will discuss these theories in our future blogs, so stay tuned! 

Second, Ladderane is designed to provide a platform for instructors to develop their own experiments to address the key learning outcomes of performing experiments such as making observations, analyzing data, and reflecting on related theories and procedures. Ladderane allows to customize a wide variety of different elements for each experiment, such as colour, chemicals, glassware, etc. For example, you can create multiple experiments for Fischer esterification using different carboxylic acids and alcohols, or use different acids and bases for titrations with different concentrations. This flexibility provides an opportunity to create a unique experiment for a group of students and thus is ideal for group work or class discussions. 

Make sure to check out our demo experiment.

Thanks for stopping by, and stay tuned for our future blogs and updates!

Ladderan's dashboard: What do you have access to?

 In this post, we provide an overview of how Ladderane allows you to create your virtual chemistry experiments or modify the existing ones.  Once your Gmail account has been activated, you can use it to log in. This takes you to the dashboard. Here, you will see a list of your virtual experiments, once you create them. You can create your own lab, by clicking on "create a new lab".  This page provides all the glassware and set-up needed for chemistry experiments. Make sure to name your experiment and save it. "Edit Items" lets you choose the glassware and chemicals needed for your reaction. "Edit setup" is for setups such as vacuum filtration, distillation, titration, etc. You can also choose various instruments such as IR, NMR,  etc. If you need a specific glassware or set-up, just let us know and we'll add it.  "Edit story" is where you can define what happens at each step.   You can then upload the lab manual and any spectra using "up

New Feature:Tracking Student Progress

  We are pleased to announce that our new feature allows you to track student progress. Tracking can be activated by enabling "Record Activities" as shown below.  Once this feature is activated, the following data will be tracked: 1. Student number or student name, depending on how students have been instructed to log in.  2. Data and time of completion. 3. Answers to the pop-up questions.  Once the experiment is completed by students, simply click on "activities" on your dashboard.  You will then have access to the information mentioned above for each student.  The answers for the questions could be used to assess learning. They could also be used as assessment for learning. This type of assessment helps to monitor student knowledge, identify misconceptions and guide instruction by providing timely feedback to students. This provides an ideal opportunity to gain an understanding of student thoughts while performing an experiment, which is an important advantage of
