In criminal proceedings involving the prosecution of an offense committed against a child under the age of 16, or witnessed by a child under the age of 16, the court on its own motion or on the motion of the party presenting the witness or the guardian ad litem of the child, may order that the testimony of the child be taken by closed circuit television or through one-way mirrors if the court determines that the testimony by the child victim or witness under normal court procedures would result in the child's inability to effectively communicate. In making this determination, the court is to consider such factors as the child's age, level of development, general physical health; any physical, emotional or psychological injury experienced by the child; and the mental or emotional strain that will be caused by requiring the child to testify under normal courtroom procedures.
