Pearson, which sold the Financial Times and Economist last year, reported its revenue had fallen nine per cent year on year during the period.
The company said headline sales were down six per cent, or four per cent in underlying terms.
In January, Pearson announced plans to cut 4,000 jobs, representing 10 per cent of its workforce.
In its interim management statement today, it said half of the 4,000 have now been notified, with the others expect to be informed in the second half of the year.
Pearson expects to incur restructuring costs of £320m in 2016 to generate annualised savings of approximately £350m.
At its annual general meeting today, Pearson said it was proposing an unchanged final dividend of 34p, giving a total dividend of 52p, up two per cent.
