Defender Martin Cranie believes Barnsley's current unbeaten run shows his side have begun to improve after a difficult start to the season.
Barnsley have won one and drawn three of their last four league matches.
The Reds, who are still in the relegation zone have closed the gap on 21st-placed Doncaster to two points.
Crainie told BBC Radio Sheffield: "We were shipping a lot of goals but we've worked a lot on that and have been better defensively."
The former Portsmouth and Coventry centre-half said having a more settled defensive line-up was also a factor.
"Me and big Jean-Yves M'voto have had a few games together now and it's been good in helping us understand how each other plays."
Cranie and M'Voto have been partnered together in Barnsley's central defence for the last four matches.
"I think the last match, the 0-0 draw against Doncaster, was actually our first clean sheet [in the league], so hopefully we can get a few more of those and keep the run going," added Cranie.
"But what we do need to do is convert the draws into wins. After the Doncaster match everyone was a bit down, because as well as missing a penalty we had a few good chances so it was probably points dropped on the day.
"The other thing is that most of the goals we've conceded have been in the second half. I don't think it's down to fitness, it's more down to concentration, and it's something we must improve.
"I think everyone is still hoping it isn't going to be like it was last season, fighting against relegation until the last day and relying on other people.
"In terms of points it looks like it's going to be a more normal season, with the 50-point mark being key, but the aim is that won't be an issue for us."
