The purpose of this study was to develop a folk science lesson about Lanna (northern) local
rituals for health promotion in HIV/AIDS patients and assess its learning effectiveness. The study
sample consisted of 49 HIV/AIDS patients selected using the purposive sampling method. The
research instrument was a questionnaire on HIV/AIDS patient’s knowledge and encouragement
gained from the Lanna local ritual lesson. Data were analyzed to determine pre- and post-
learning effectiveness (E1/E2) ratio and paired t-test value.
The results showed that the E1/E2 ratio or score of HIV/AIDS patients’ knowledge before
and after taking the Lanna local ritual lesson was 80.01/86.78 The post-learning achievement
score was significantly higher than the pre-learning score at the statistical significance level of
0.05 (p-value = 0.002). The study suggested that local health agencies should adopt the Lanna
local ritual lesson on HIV/AIDS patient’s health promotion as a ritual healing approach to pro-
mote the use of Lanna local wisdom for health promotion of local residents.
Key words: evaluation of local science lesson, health promotion for HIV/AIDS patient, Lanna
