Narrative:

During descent into ZZZ; first officer was keeping power in and spoilers out to keep power up enough for wing anti ice. This caused him to not slow down earlier. We were descending through clouds and light rain and accrued moderate rime during the descent. We made a pirep for this. First officer was late therefore to reduce speed and had to do it while getting vectored onto the localizer. Also; vector given to us was through localizer which added further confusion. He reduced the power after I told him to slow and we got flaps and gear out as quickly as possible. First officer has only been here since summer and I am on my second trip off of operating experience as a ca. I should have determined why he was waiting to slow and told him to simply reduce the power and not worry as much about keeping it up for the anti-ice. We were late to get stable on the approach. Then; we got a low speed cue and a brief shaker which cued us to the fact that the spoilers had been accidentally left out. At this point; we should have executed a go around. Given that I am so new; I still feel behind the airplane at times; especially when the first officer is new and struggling and we are in a high workload environment. Next time I have an issue with an first officer on an unstable approach I will call the go around.

Title: CRJ-200 flight crew reported that they kept the power up for de-icing causing the aircraft to be fast and unstable on approach.

Narrative: During descent into ZZZ; FO was keeping power in and spoilers out to keep power up enough for wing anti ice. This caused him to not slow down earlier. We were descending through clouds and light rain and accrued moderate rime during the descent. We made a pirep for this. FO was late therefore to reduce speed and had to do it while getting vectored onto the localizer. Also; vector given to us was through localizer which added further confusion. He reduced the power after I told him to slow and we got flaps and gear out as quickly as possible. FO has only been here since summer and I am on my second trip off of operating experience as a CA. I should have determined why he was waiting to slow and told him to simply reduce the power and not worry as much about keeping it up for the anti-ice. We were late to get stable on the approach.

Given that I am so new; I still feel behind the airplane at times; especially when the FO is new and struggling and we are in a high workload environment. Next time I have an issue with an FO on an unstable approach I will call the go around.
