In the currently prevalent “rat race” phenomenon, which is particularly acute in the field of education. When it comes to discussing the factors underlying the changes in middle school students' English academic achievements, numerous researchers have put forward their viewpoints from different perspectives. This paper summarizes four crucial dimensions that impact middle school students' English achievements and conducts a six-week teaching experiment based on these dimensions. Through the analysis of questionnaire surveys, interviews, and experimental comparisons, it is discovered that the factors influencing students' English achievements, ranked in order of importance from high to low, are: family rearing style, communication and emotional support between parents and children, parents' expectations, and family culture and values. However, while parental expectations have a direct and positive impact on adolescent children, they rank third among the major factors and have a relatively low impact. On the other hand, in the context of family rearing methods that are not suitable for children's development at this stage and incorrect family communication and emotional support, parents' expectations have indirect negative effects.
