In this animated activity, learners view how to clear and preset a flip-flop to store a logic 0 or a logic 1.

In this interactive object, learners solve additional problems involving total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

Students view a video that shows the correct methods for starting a GTAW weld pool and adding filler. It focuses on the two problems that many students have – adding filler too soon and angling the torch so that the filler melts prematurely on the filler rod. Note: This activity is 3.6 mb.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

The schematic symbols of logic gates used in digital circuits are shown.

In this learning activity you'll practice converting between hexadecimal and decimal and between hexadecimal and binary numbers.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.

Our students interact on the internet everyday, but do they know how to do so responsibly? Review key ideas related to implementing ISTE’s National Educational Technology Standards (NETS) in regard to ethical and social issues.

Use the arrow keys to direct the snake towards the type of logical fallacy in the example sentences.
