March 2004
What is “Studio Format”? : What is “Studio Format”? MBL tools:
Student-centered learning of physics concepts and investigative skills through guided activities enhanced by use of microcomputer-based laboratory (MBL) tools Electronic sensors (motion detectors, force probes)
Microcomputer interface (ULI)
Software for data collection and analysis (Logger Pro, Excel) Real-time collected data may be analyzed quantitatively Adapted from D. Sokoloff, R. Thornton, and P. Laws
What is “Studio Format”? (cont’d) : What is “Studio Format”? (cont’d) Goals:
Acquire understanding of related physics concepts
Give direct experience of physical world using MBL tools for real-time data collection, display, and analysis
Enhance traditional laboratory skills
Reinforce topics in class and readings using conceptual activities and quantitative expts. Use learning cycle of prediction, observation, comparison, analysis, and quantitative experimentation
What is “Studio Format”? (cont’d) : What is “Studio Format”? (cont’d) Arrange laboratory setting to maximize learning using this group method Experiments and activities work best when 2-4 students are arranged into collaborative groups

Student Comments Physics 110 : Student Comments Physics 110 What aspects of the laboratory are most helpful to you in learning physics? “Actually seeing this stuff work. Getting beyond the book and seeing not just how, but why this works. The ‘concepts’ don’t mean anything to me unless I see them at work.”
“The ‘hands-on’ experience that let me see the laws of physics discussed in class are actually true in real life; I could better grasp the concept by seeing it for myself.”
“Actually seeing how the equations are applied to physical motion. Using Excel to collect and analyze our data was helpful in other classes as well as this one.”
“Working with partners, and getting a hands-on application of the concepts.”
“Working in groups and using all the different equipment.”
“The lab actually did stuff we had to know for class. Every other lab I have ever had has not dealt with the class as much but this one has. This lab was the most related to the topics we were going over in class.”
Slide14 : What improvements could we make in the labs to help you learn more? “Better instructions, more than one lab instructor, and preferably shorter labs.”
“Directions that make clear and concise sense. Sometimes it seems like the instructions are harder than the lab itself.”
“Covering material in class before doing it in lab.”
“Since physics is a hard subject for many to grasp, a more thorough explanation before each lab would be helpful. We can’t learn and understand things from lab if we don’t understand the concepts to begin with. And considering half the labs we did were before our teacher covered the material in class. So rather than just an equipment demonstration, a quick lecture would help greatly.”
“Perhaps some less ‘structured’ laboratory experiments. Instead labs that require us to think more.” Student Comments Physics 110
