PP+ Series vs Math Geometry

The Series and Parallel Circuits lab uses resistors, a power supply, a voltmeter, and an ammeter to investigate the effective resistances of circuits with resistors in series, in parallel, and in combinations of series and parallel components. It is part of Polyhedron Physics Plus, a set of 24 iPad apps for use in the classroom. To see how they work, try the FREE PP+ Newton’s 2nd Law lab. For those who’d prefer to develop their own experiments, the PP Series-Parallel Circuits app features a similar apparatus without lab procedures and other supporting materials. In addition to a 3D simulation that produces realistic data, each lab includes introductory videos, background theory, experimental procedure, analysis and reporting tools, pre-lab quiz, post-lab questions, and teacher support materials. The experimental data produced by the simulations are realistic, including random and systematic errors. These features allow students to use standard data analysis and error analysis techniques to report on their own unique data, just as if the experiment had been performed using hands-on equipment. These labs can serve as replacements for hands-on labs, especially when equipment is not available, or as supplements to hands-on labs. They are also a suitable option for students in distance learning and home school situations. Formative and summative evaluations showed no significant difference in learning between students using the virtual labs and those using hands-on labs. Preliminary results suggest increased learning by students using the virtual labs as supplements to hands-on. Polyhedron Physics was developed by Polyhedron Learning Media, Inc. with partial funding provided under contract numbers ED-07-CO-0040 and ED-IES-11-C-0029 from the Institute of Education Sciences in the U.S. Department of Education through the Small Business Innovation Research (SBIR) program.

“Math Geometry: Learning 2D and 3D Shapes” is designed for school teachers and children aged 5-10 years to study 2D and 3D shapes, and the attributes of shapes. The app contains the hi-quality figures and provides a fun and interactive way to learn the shapes, so your kids will love this app. The app provides following functionality / topics / concepts: • Learning and testing 2D Shapes and their attributes – sides and corners • Learning and testing 3D Shapes and their attributes – vertices, faces and edges • Ability to rotate any 3D shape in any direction – it is a fun and effective way to memorize each shape • Different question types: identifying a shape by a given picture, by a given name and by its attributes • Manage the test content – you can exclude/include a specific shape from the test content • Choose the number of questions – from 10 to 40 • Progress report – ability to see the latest and best student results by test type (2D / 3D) and by question type (shape names / attributes of shape) • Ability to see the correct answer, and learn the related shapes when the student makes a mistake. This option is configurable, so it can be switched off if required • Ability to reset the statistics • Sound control Enjoy!
