【摘要】：本研究旨在研究小學(xué)生雙位數(shù)乘法運(yùn)算的策略對于乘法運(yùn)算結(jié)果的影響,以及工作記憶的各個成分對于多位數(shù)乘法運(yùn)算和策略選擇的影響。實(shí)驗(yàn)一使用被試間設(shè)計,三組被試分別在使用結(jié)合律策略、使用分配率策略、以及可自由選擇兩種策略之一三種條件下對雙位數(shù)乘法進(jìn)行運(yùn)算,記錄反應(yīng)時和正確率。結(jié)果顯示使使用用分配率策略組反應(yīng)時明顯低于使用結(jié)合律和自由選擇策略組,使用結(jié)合律組與自由選擇策略組之間的反應(yīng)時沒有顯著差異,三組被試的正確率沒有差異。在策略自由選擇上,被試選擇分配律的頻率高于結(jié)合律,并且會受到題目類型的影響。實(shí)驗(yàn)二使用被試內(nèi)和被試間的混合實(shí)驗(yàn)設(shè)計,三組被試分別在中央執(zhí)行受干擾、語音環(huán)路受干擾和視空受干擾三種條件下依次使用自由選擇策略、結(jié)合律策略和分配律策略進(jìn)行雙位數(shù)乘法計算。結(jié)果發(fā)現(xiàn),三種干擾下的策略選擇并無差異。中央執(zhí)行干擾組和視空干擾組之間反應(yīng)時差異顯著,在中央執(zhí)行干擾下,被試的反應(yīng)時更長。語音干擾組和視空干擾組之間正確率差異顯著,相對于視空干擾,在語音干擾下被試的反應(yīng)時會更高。中央執(zhí)行組和語音干擾組之間差異不顯著。結(jié)果表明,在使用不同運(yùn)算策略情況下,視空模板的干擾效應(yīng)要低于語音環(huán)路的干擾效應(yīng)和中央執(zhí)行系統(tǒng)的干擾效應(yīng)。
[Abstract]:The purpose of this study was to study the effect of the strategy of double-digit multiplication on the result of multiplication, and the effect of each component of working memory on multi-digit multiplication and strategy selection. Under the conditions of using combination law strategy, using allocation rate strategy, and freely choosing one of the two strategies, the three groups of subjects were able to perform operations on double digit multiplication, respectively. The results showed that the response time of the group using the allocation rate strategy was significantly lower than that of the group using the combination law and the group of free choice strategy, but there was no significant difference between the group using the combination law and the group of the free choice strategy. There was no difference in the correct rate among the three groups. In the free choice of strategy, the frequency of the allocation law was higher than that of the combination law, and it would be affected by the type of question. The three groups of subjects performed double-digit multiplication calculations under the conditions of central interference, speech loop interference and visual spatial interference, respectively, using the free selection strategy, combining the law strategy with the allocation law strategy. There was no difference in the choice of strategies between the three kinds of interference. There was significant difference in the response time between the central executive interference group and the visual space interference group, and the response time was longer in the central executive interference group, while the correct rate difference between the speech interference group and the visual space interference group was significant. There was no significant difference between the central executive group and the speech interference group. The results showed that in the case of using different operational strategies, the response time of the subjects was higher than that of the visual and spatial interference, and there was no significant difference between the central executive group and the speech interference group. The interference effect of visual space template is lower than that of speech loop and central executive system.
