[Purpose/significance] Online education review is an important factor that affects users' choice and use of online courses. Studying the usefulness of online education reviews can help users make decisions, enhance users' willingness to use, and promote the iterative update of online education products. [Method/process] This paper used questionnaire surveys and experimental research methods to analyze the emotional polarity of online reviews (positive evaluation, negative evaluation), product types (search online education products, experience online education products, trust online education products) on the impact of the perception of the usefulness of online educational reviews, and also studied the impact of the usefulness and credibility of online educational review information on the willingness to use online educational review information. [Result/conclusion] The results of the study indicate that the negative reviews of search-oriented education products and trust-based education products are more useful than positive reviews, while the sentiment polarity of search-oriented education products has no statistically significant difference in the usefulness of reviews. When the online education review information is fixed as positive review, the adjustment effect of online education product type on perceived usefulness is not very significant, however, when the online education review information is negative review, the online education product type has a significant regulatory effect on the usefulness of online education review.
