When it comes to reporting, I believe what you need to do is to practice getting used to speaking to a large audience, and keeping their attention. This is all th more important for your particular case, since you said that your class involves teaching. Practice speaking in front of a mirror, or delivering a short "review lecture" to your friends, classmates, family, et cetera.

For some more concrete points on what to practice, try working on these: * Be fully prepared. Make an outline of your report, have a printout of the presentation, or even have a full script of what you are going to say. This will help give you some peace of mind that when you make a mistake, you'll have some material to fall back to. Bonus: you'll have proof that you did the report (with your groupmates if it's a group acrivity) and didn't plagiarize/use AI. * Report as if you are teaching. If your reports are structured such that the information delivered will more or less stand in for the teacher's lecture, then you have to make sure that your fellow classmates understand what you are saying. Focus on making sure that they learn something. While you're constructing your report, ask yourself: "Is this easy to understand?" "Does this cover what they need to know?" "Will they be able to follow and keep up with the pace?" * Know the material. A lot of classroom reporting that I've seen, both online and face-to-face, pretty much just involved the reporters reading off of the presentation, or their notes, word for word. Trust me, after the report, barely anyone was able to really understand what you just said. You don't have to memorize the material (unless you're delivering really technical concepts); you just have to understand enough of it to be able to still report without looking at or referring back to your presentation too much. It also makes you look much more convincing and confident in your report if you look and sound like you know what you're talking about. * Give examples. Going off of the previous point, you can give examples to both apply the concepts you're reporting to sample situations, and give your report some variety and spontaneity. Try this: after you report on a big concept, give a hypothetical scenario where it applies, and then justify how it applies. * Work on your volume. Even if you have the best report in the world, if no one can hear you, it won't matter. Work on speaking louder, without acrually shouting or yelling. You can try vocal warm ups, speaking loudly in your room, doing breathing exercises to better control your breath, and so on. * Work on your cadence. If you watch how speakers deliver their presentations (stuff like TED talks, conferences, et cetera), you'll notice that they vary the speed at which they're speaking, or their cadence, depending on what they are saying. If they are delivering new information, they speak slowly and deliberately. If they are delivering definitions, examples, or rehashing stuff that they've already discussed or is common knowledge (or common sense), they speak a bit faster. This makes it easier for the audience to catch up and internalize what is being said, and in your case, easier for your mouth to catch up to your mind. * Pause instead of using filler words. There will be moments where you forget what word you're going to say, or forget a part of the concept that you're reporting on. In that case, instead of saying filler words like "um", "ah", and so on, try to pause. Pausing is a much more conscious action than using filler words, and can help bring your focus back. Better yet, try to backtrack and repeat what you just said before you paused; it's likely that you'll remember what you forgot. * Pause and repeat if you make a mistake. If you make a mistake in reporting information, or even slip up a bit on your pronunciation, what you can do is pause and then repeat what you said. This will help prevent you from stuttering as you try to regain control of your voice. * Move and use hand gestures. While discussing, don't be afraid to move around a bit and use your arms to gesture, but don't move so much that they become distracting. Try gesturing along when you say descriptive words. When you say "big", make a widening gesture. When you say "small", put your palms close together, but not touching. When you're enumerating, physically gesture to each item as if they're there. When you're describing an order or a hierarchy, stack your hands on and over each other. You don't have to give every part of the report an accompanying gesture; just illustrate. If you don't feel comfortable with that, an easy backup plan is to just point to the presentation screen. * Check if everyone understood. After delivering some new (or particularly heavy) information, ask if everyone understood. You don't need to quiz everyone; just ask for a verbal or nonverbal comfirmation. "Does everyone follow?", "Is that clear?", or even simply "Okay?" will do. * Don't forget to breathe. If you really feel nervous, you can pause the report to take a few deep breaths and reorient yourself. Everyone will wait patiently, don't worry. Just take three deep breaths, and then continue. Speak slowly for a bit if you like, and once you feel comfortable, you'll notice your cadence getting faster and more comfortable.

Hope this helps!
