Is summer and winter are caused by the earth's swinging back and forth 23.5 degrees from the vertical?

Well, kind of. The earth doesn't actually swing at all- it has an axial tilt of 23.5 degrees, but it's always pointing in the same direction (precession notwithstanding- irrelevant for this question). Picture the earth orbiting around the sun with an arrow pointing out the top. The arrow is tilted 23.5 degrees to the side, of course. Now on one end of the orbit, the arrow will be pointing toward the sun, and on the other it will be pointing away.
When the arrow is pointing toward the sun, the northern hemisphere has more direct exposure to sunlight, and that's what makes it summer. This is also why it's winter in the southern hemisphere at the same time.
I included a link below to an animation that shows this quite clearly.

How are season caused?
Seasons are caused by the positon of the earth along its orbit around the sun AND the tilt of the earth. Summer is caused when the sunlight is more direct in a hemisphere (northern or southern) and causes warmer temperatures. Winter is just the opposite: when sunlight is less direct.
