The purpose of this study is to determine the effect of Content Journal as a monitoring tool to improve the achievement of students in Chemistry. An intact class of the Grade 10 level composed of 36 students from St. Mary Magdalene School, Kawit, Cavite during the fourth quarter of the school year 2019 – 2020 was involved in the study. Single group pretest - posttest design was used as the research design. The students included in the study were chosen through purposive sampling. The study utilized four instruments namely; Content Journal in Chemistry 10 booklet, Lesson plan, DICES rubrics for constructed response, and Chemistry Achievement Test (CAT). Descriptive statistics such as mean and standard deviation were used. The paired t-test was used to determine the difference between the pretest and posttest means in the CAT at 0.5 level of significance. The findings of the study revealed that the CAT posttest mean is higher than the pre-test mean. There is a significant difference in the pretest and post test scores of CAT. The p-value obtained was 0.00001 which is less than the level of significance set for the study (p < 0.05). There is a significant difference in the achievement of learners before and after using Content Journal, thus rejecting the null hypothesis. Content Journal showed to have a positive effect on the achievement of students. Journal entries were also analyzed using descriptive statistics and qualitative analysis to determine the performance of students in terms of their content knowledge and personal learning experiences conveyed through reflection.
