The present study aimed at investigating whether academic IELTS candidates perform differently in writing on either a chart topic or a table topic of the IELTS writing task 1 with regard to the four IELTS writing marking criteria i.e. task achievement, coherence and cohesion, lexical resource, and grammar range and accuracy. The study adopted a mixed methods approach. To this end, 45 candidates participated in the study. In the beginning, the participants were asked to write on a chart topic of the IELTS writing task 1. After 10 days, the same groups of participants were given a table topic of the IELTS writing task 1. All their papers were then marked and analyzed quantitatively in accordance with IELTS writing task 1 descriptor. Next, paired-samples statistical analyses were run to find out how they performed. The results revealed that the participants' writing performance on a chart topic was significantly higher than a table topic in terms of task achievement, lexical resource, and grammar range and accuracy scores. Concerning the qualitative side of this study, there was a significant difference between candidates’ performance in chart and table topics with respect to task achievement and lexical resource. However, the results did not manifest any significant differences between candidates’ performance getting chart and table prompts in terms of coherence, cohesion, and grammar range and accuracy.

本研究旨在调查雅思学术考生在雅思写作任务 1 的图表主题或表格主题的写作中是否在四个雅思写作评分标准方面表现不同，即任务成就、连贯性和衔接、词汇资源和语法范围和准确性。该研究采用混合方法。为此，45 名候选人参加了研究。一开始，参与者被要求在雅思写作任务1的图表主题上写作。10天后，同组的参与者被给予雅思写作任务1的表格主题。然后对他们的所有论文进行评分和分析根据雅思写作任务1描述符进行定量。接下来，进行配对样本统计分析以了解它们的表现。结果显示，参与者在任务完成、词汇资源、语法范围和准确度得分方面，图表主题的写作表现明显高于表格主题。关于这项研究的定性方面，考生在图表和表格主题中的表现在任务完成和词汇资源方面存在显着差异。然而，在连贯性、衔接性、语法范围和准确性方面，考生的表现并没有表现出任何显着差异。在任务完成和词汇资源方面，考生在图表和表格主题中的表现存在显着差异。然而，在连贯性、衔接性、语法范围和准确性方面，考生的表现并没有表现出任何显着差异。在任务完成和词汇资源方面，考生在图表和表格主题中的表现存在显着差异。然而，在连贯性、衔接性、语法范围和准确性方面，考生的表现并没有表现出任何显着差异。
