چکیده

هدف این مطالعه بررسی اثر بخشی راهبرد آموزی مبتنی بر الگوی ویت بر بهبود عملکرد حافظه‌ی فعال و عملکرد ریاضی دانش‌آموزان پایه‌ی سوم دبستان دارای حافظه‌ی فعال ضعیف بود. در این پژوهش شبه آزمایشی 36 دانش‌آموز دارای حافظه‌ی فعال ضعیف و عملکرد تحصیلی ریاضی پایین به شیوه‌ی خوشه‌ای انتخاب شده و در یک گروه آزمایشی و دو گروه کنترل جایگزین شدند. گروه آزمایشی به مدت 6 هفته بر اساس الگوی ویت تحت آموزش حافظه‌ی فعال قرار گرفتند. به گروه پلاسیبو 6 هفته درس علوم از طریق شیوه‌ی آموزش دو جانبه، آموزش داده شد و گروه کنترل واقعی هیچ نوع مداخله‌ای را دریافت نکردند. برای تجزیه و تحلیل داده‌ها از روش آمار توصیفی، تحلیل واریانس چند متغیره، تحلیل کواریانس یک طرفه و آزمون تعقیبی بن فرونی و نرم‌افزار SPSS-20 استفاده شد. نتایج پژوهش نشان داد که مداخله سبب بهبود عملکرد دانش‌آموزان در آزمون‌های یادآوری وارونه، شمارش و مکعب شده است، ولی افزایش در آزمون یادآوری مستقیم معنادار نبود. همچنین نتایج نشان دادند که عملکرد ریاضی دانش آموزان گروه آزمایش نسبت به دو گروه دیگر افزایش یافت. یافته‌ها حاکی است که عملکرد حافظه‌ی فعال و عملکرد ریاضی دانش‌آموزان با مداخلات مناسب در حافظه‌ی فعال قابل بهبود است.

چکیده [English]

The purpose of this research was to study the effectiveness of strategy training using Witt's model on the improvement of working memory and math performance among third grade primary school students with low working memory levels. In this quasi-experimental design, 36 students were selected with low working memory and low academic math performance. These students were randomly assigned in three groups (one experimental, one placebo and one true control groups). The experimental group was trained based on Witt's model for 6 weeks. The placebo group were taught science using the reciprocal method, while the true control group didn't receive any treatment. To analyze the data, MANOVA, ANCOVA and the Bonferroni test were used through SPSS 20. Results showed that the intervention improved the students' performance in backward digits, counting and block recall tests, but the enhancement in forward digit recall test was not significant. Also, results indicated that the students' math performance had improved. According to the findings, the students' working memory and math performance can be improved with appropriate interventions in the working memory.
