ElNet has three interesting webinars coming up. ElNet is the E-learning Network of Australasia. It's an independent community of e-learning professionals working in the e-learning industry. One presenter is Cathy Moore - I love her approach to Instructional Design and sometimes use her eLearning Blueprints with clients.
I've been holding back on developing an authoring tool for STEM, mainly because I want to develop more experience in planning, writing and developing these interactions. The first couple I developed focus on using sticky notes on a whiteboard. This had some positives and negatives.
