Learners identify various therapeutic interaction strategies to be used when working with children and adolescents to enhance self-esteem, self-concept, self-worth, body image, and coping and communication skills.

Learners complete a crossword puzzle with terms that relate to common diseases of the nervous system and mental disorders. Immediate feedback is provided. Learners have the option to send an e-mail to their instructors notifying them that the learning object has been completed.

In this learning activity, learners will reflect on the meaning and impact of stereotypes in both personal relationships and work environments. Identifying behaviors, attitudes, and feelings associated with stereotypes are addressed in this activity.

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

Learners examine the fundamentals of a pulse train. Concepts such as time on, time off, duty cycle, period, and frequency are covered.

Students read about the characteristics of the ideal operational amplifier and compare them with the industry standard LM741C.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

Students read an explanation of the summing amplifier and the formulas for closed-loop gain. An example is given.

Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.

The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.
