From Ervin A. Gonzalez comes "Direct Examination," where you'll find these tips:
During the trial, develop the direct examination through the use of conversational language. Avoid reading questions to the witness. This will bore the jury and leave them with the feeling that the presentation was rehearsed. You may have your outline present, but use it only as a reference and not as a script. Remember to guide the witness through the testimony so that she does not ramble.
Consider mentally placing yourself in the shoes of a news reporter or investigator at the scene of a breaking story. Wipe out the knowledge that you have of the case and attempt to become educated on the issues through the witness on the stand. Ask the types of questions that a reporter or investigator would ask to become fully informed of what happened in the case. This technique will allow you to view the case from the jury's perspective. Remember you may know everything about the case, but the jury is hearing the testimony for the first time at trial.
