The study aims to investigate theses of life education of junior high schools by using content analysis so as to know its current state and trend. The study covers those theses from 2000 to 2017 with a total of 120 master’s theses focusing on junior high school students. The themes of the analysis cover basic data, research subjects, methodology, and outcomes from the selected theses. The research findings are as follows: 1. Amount: After 2008, there were at least 5 theses a year. It is conservatively estimated such an increasing trend will continue with the support of governmental policies. 2. Distribution: The majority of theses were conducted in some of northern and southern universities in Taiwan, especially directed by some specific professors. 3. Theme: Teaching-related theses were rank the top one, while those investigation-related theses on perception of life education the second. These two categories have steady percentage each year, while content-related theses are increasing dramatically in last two years. 4. Discipline: The theses integrated with humanity and social science areas have the highest percentage, while those with science and math areas have lower percentage. The reason why art and humanity theses outnumbered was because of paper-and-pencil assessment free and was excluded from entrance exam. 5. Methodology: The majority of experimental studies applied t-test in their either dependent-sample or independent-sample studies. Investigation-typed theses outnumbered others possibly due to high feasibility. 6. Duration of study: The perception of life education and the change of life attitude could not reach statistically significant difference within a short period of time. It is highly suggested that the duration of study can be extended to at least 8 weeks so as to have a better expectation.
