“The word ponder means to consider, contemplate, reflect upon, or think about. Pondering the scriptures, then, is reverent reflecting on the truths, experiences, and lessons contained in the standard works. The process of pondering takes time and cannot be forced, hurried, or rushed.

…

Writing down what we learn, think, and feel as we study the scriptures is another form of pondering and a powerful invitation to the Holy Ghost for continuing instruction.”

-Elder David A. Bednar, “Because We Have Them Before Our Eyes,” April 2006 New Era

As gospel learners, we should be “doers of the word, and not hearers only” (James 1:22). Our hearts are opened to the influence of the Holy Ghost as we properly exercise agency and act in accordance with correct principles—and we thereby invite His teaching and testifying power. 
-Elder David A. Bednar, "Watching With All Perseverance," April 2010 General Conference

Most of the teaching in the world is based on one of the five senses—hear, see, touch, smell, or taste. In your classroom you can teach by the power of the Spirit.

Such communication begins by your encouraging each one you teach to participate rather than be a passive listener. In this way you can assess their understanding of what is taught, create a feeling of ownership, and also learn from them. More important, their decision to participate is an exercise in agency that permits the Holy Ghost to communicate a personalized message suited to their individual needs. Creating an atmosphere of participation enhances the probability that the Spirit will teach more important lessons than you can communicate.

That participation will bring into their lives the direction of the Spirit. When you encourage students to raise their hand to respond to a question, while they may not realize it, they signify to the Holy Ghost their willingness to learn. That use of moral agency will allow that Spirit to motivate them and give them more powerful guidance during your time together. Participation allows individuals to experience being led by the Spirit. They learn to recognize and feel what spiritual guidance is.

-Elder Richard G. Scott, "To Learn and to Teach More Effectively," Education Week Devotional address, August 2007

-also quoted in "The Spirit is the Real Teacher"

A learner exercising agency by acting in accordance with correct principles opens his or her heart to the Holy Ghost and invites His teaching, testifying power, and confirming witness. Learning by faith requires spiritual, mental, and physical exertion and not just passive reception.
-Elder David A. Bednar, Seek Learning by Faith, Sept 2007 Ensign
