I am a volunteer Online Advisor for the Learning Center. I'm happy to answer any questions you might have about the Learning Center!
I started my teaching career in Surry County, Virginia, teaching high school sciences. I have been at Embry-Riddle Aeronautical University for six years. These days, I split my time between teaching sciences (Chemistry and Environmental Science) and administrative responsibilities. I hope to start working more with undergraduate researchers.

There are companies that sell mail-order lab kits. However, some of them have experiments that I do not feel meet the safety standards for unsupervised at-home experimentation. (For example, MEL offers a magnesium-burning experiment. We also have to consider hazardous wastes generated. I'm not sure where the law sits on this, but I err on the side of caution and assume if it would be consider...

The answer to this is going to vary by grade level and STEM discipline. There are many safe "kitchen chemistry" activities children of many ages can participate in safely. If you provide more information on grade level and topic, I'm sure there will be some really interesting suggestions from the community.

Are you looking for platform suggestions for recording? I've used an iPad to record a short demonstration and posted it to the LMS in a discussion thread and then asked targetted questions throughout a week-long discussion of the demonstration.

Tue, Mar 24, 2020 10:24 AM Formative Assessment in STEM
The authors present a unique approach to collecting information about formative assessment by using a trained undergraduate student as a "learning researcher". This person makes observations and asks exploratory questions in order to provide the instructor with a daily report from the front lines of learning tasks. This study states benefits to both instructors and the learning researchers.
Overall, this is an interesting approach to evaluating one's teaching as well as student learning ahead of a deliverable or major assessment.
Tue, Mar 24, 2020 10:17 AM Explanatory Thinking with Mobile Devices
This article provides a great overview of explanatory thinking, including student work using this pedagogical approach (Figure 1). The reported student perspectives and the student model development are compelling. It would have been interesting to see if there was a correlation between some of the student perspectives, though. For example, I am curious if there was a correlation between Question 3 and Question 4 responses (see Figure 4). Overall, strong article on combining a constructivist approach with mobile learning to enhance student motivation and learning.
Point of View: Confusing Science Vocabulary: When Negative Is Positive!
Thu, Feb 20, 2020 11:58 AM Science Vocabulary
This is a great piece that explains how students can struggle with words that have one meaning in science but another in other disciplines or their personal life. One I see my students struggle with is the idea of a theory - which has a specific meaning in science but is more equivalent to a hypothesis in lay uses I tend to come across.
This piece has encouraged me to do some self-reflecting to see how I can improve the vocabulary in my chemistry and environmental science classes to avoid confusion.
