Summary: 
The study aims to propose and pilot a design process for Technology-based STEM lessons at the lower secondary level, based on the 6E model. Despite the widespread implementation of STEM education, organizing STEM lessons within the Technology subject currently faces significant challenges due to the lack of a standardized pedagogical process, specifically, a shortage of research applying the 6E model integrated with an engineering design phase tailored to the subject’s specific characteristics. The study used a quasi-experimental design involving 60 eighth-grade students at Vinh Loc A secondary school, comprising an experimental group of 30 and a control group of 30. The experimental group studied the topic “Automatic control circuits” using the proposed procedure, while the control group studied the same content using the conventional teaching method. Data was collected through tests, product assessment rubrics, classroom observation records, and student feedback forms. The results showed that the experimental group achieved a mean score of 7.23 ± 1.50, which was higher than that of the control group (6.40 ± 1.67). The mean difference between the two groups was 0.83 points, with a Cohen’s d effect size of 0.52. Qualitative data indicate that the 6E process supports students in activities such as problem identification, design, assembly, testing, and product presentation.
