ABSTRACT
The purpose of the study was to develop content and language integrated learning Based instructional material in cell biology. Specifically, this paper aimed to determine the least learned competencies in cell biology, language difficulties used in science, instructional materials based in CLIL designed for teaching Cell Biology in Junior High School, and a significant difference between the scores of the students before and after the implementation of the instructional materials. One Hundred Eighty junior high school grade 7 students were randomly chosen as the participants from the 3 participating schools. Descriptive Statistics such as frequency, percentage, and weighted mean were employed in the data analysis. The result shows that among of the least learned competencies Cell Function has the lowest mean of 5.55 with a standard deviation of 1.53. Followed by Cell Organelles with a mean of 5.55 with standard deviation 1.70 and Cell Structure has the highest mean of 6.05 with standard deviation of 1.435 respectively. The respondents who were asked regarding their language difficulties in learning science, 96% of them considered vocabulary as a hindrance in learning science. On the other hand, 65 % believed that dialect differences made it difficult for them to learn science. While 52 % believe in no clear speech as a factor contributing to the difficulties in learning science. The mean of 8.04 of the students’ scores recorded after the implementation of the instructional materials contrary to the mean of 5.82 before its implementation. It could be observed that the mean score after the implementation of the instructional materials is higher by 2.22. This might imply an improvement in students’ scores after using instructional material. Hence, there is a significant difference between the scores of the students before and after the implementation of the instructional material. It could be implied that instructional materials potentially help the students understand the science cell biology topic.
