To prepare crisp, combine the first 6 ingredients in a large bowl; toss to combine. Spoon mixture into an 11 x 7-inch baking dish coated with cooking spray.
To prepare topping, lightly spoon flour into a dry measuring cup; level with a knife. Combine flour, oats, sugar, 1/8 teaspoon cinnamon, and dash of salt in a small bowl; stir to combine. Cut in butter with a pastry blender or 2 knives until mixture resembles very coarse meal. Sprinkle oat mixture evenly over pear mixture. Bake at 375° for 50 minutes or until browned on top. Serve with whipped topping.
