This site contains a large collection of interactive activities in both math and science. It contains interactive, adaptive practice activities that cover a wide variety of math and science content.
Type of Material:
Drill and Practice
The site can be used as an interactive activity both in class or at home individually or with groups.
The site does not work properly with Internet Explorer. I suggest to use the latest version of Mozilla Firefox or Chrome.
Identify Major Learning Goals:
The CK-12 PLIX Series covers concepts in Arithmetic, Algebra, Geometry, Calculus, Trigonometry, Probability, Statistics, Measurement and Analysis.The site is interactive providing interaction between learner to content, learner to learner and learner to instructor. The goal is to allow students to explore the relevant concepts and then assess their understanding
Target Student Population:
Learners from K-12 taking Arithmetic, Geometry, Trigonometry, Probability, Statistics, Algebra, Measurement, Analysis or Calculus.
Prerequisite Knowledge or Skills:
Some basic knowledge of the concepts that the specific activity is addressing.
The site provides well designed animations for the learners to grasp visually and kinetically the concepts. The student is first presented an exploration that will help lead the student to the main ideas that the item addresses. Then the student is given a few multiple choice quiz questions that test for understanding. Finally there is an open ended discussion question that is meant to be worked on by a group. The activities are creative and will lead students to a greater understanding of the topics.
There are several grammar errors in the quiz questions. Some make the question particularly difficult to understand. For example, "The function square root of x on the interval [0,10] satisfies all the for the mean value theorem." True or false?
I was not able to access the Analysis portion. Also, I had to close the browser completely to be able to open a different subject.
Potential Effectiveness as a Teaching Tool
The features are outstanding because the learner can grasp different mathematical concepts not only by reading but by interacting with the content. Additionally, at the end of every Challenge Me question, there is at least one discussion that can be integrated in a lesson so learners can reflect in the concepts learned. This collection of activities can serve as a helpful supplement to several courses in mathematics and science.
The site freezes after one subject is covered which may frustrate students and distract them from their learning. Also, there are no links provided to additional coverage of the materials that the activity addresses.
Ease of Use for Both Students and Faculty
The site is very easy to use and navigate. There are instructions provided for every step so that the student will not get confused about what is expected.
After the last question of each activity is completed the program goes back to the first step instead of either providing the student with an analysis of understanding or suggesting to move on to the next topic.
