Abstract:

This quasi experimental research aimed to determine the level of students' science skills and knowledge in guided and open inquiry-based learning on the lessons of photosynthesis and cellular respiration among second year high school students of a Catholic High School in Aklan during the school year 2011-2012. This study was conducted among two classes of second year high school students. One class underwent guided inquiry-based learning and the other, with open inquiry-based learning. Before the intervention, each class was given a pretest with two sets of questionnaires. A set of questionnaire was given to assess their science skills and the other one to assess their knowledge on the two lessons. The test questions had undergone validation and reliability testing before their actual use. Journal writing served as a supplementary investigation to uncover patterns of inquiry skills manifested among the students. Mean and standard deviation were used as descriptive statistics to describe the science skills and knowledge of the students prior to and after exposure to guided and open inquiry-based learning. The results revealed that prior to and after exposure to guided and open inquiry-based learning, the students possessed conceptual understanding and factual recall of photosynthesis and cellular respiration concepts. As for the science skills, students demonstrated applying concepts and analysis prior to exposure to guided inquiry-based. Prior to exposure to open inquiry-based learning, students demonstrated science skills of applying concepts, analysis, interpreting graphics, and inferring. After exposure to both guided and open inquiry-based learning, students demonstrated science skills of applying concepts, analysis, interpreting graphics, and synthesis/evaluation. As for the inferential statistics, Wilcoxon Signed-Rank Test was used to compare mean pretest scores and mean gain scores of science skills and knowledge of students exposed to guided and inquiry-based learning, Mann-Whitney Test for independent sample was used to compare the pretest and posttest mean scores in biology of the guided and open inquiry-based learning groups, and Spearman's Rank Correlation Coefficient was used to ascertain significant relationships between the science skills and knowledge of the students exposed to guided and open inquiry-based learning. Significance was set at .05 alpha level. Results showed that there was no significant difference in the mean pretest scores of biology of the two groups, implying that they were comparable at the start of the study. Moreover, there was no significant difference in the mean gain scores of science skills and knowledge of the two groups; however, there was a significance difference in the mean posttest and mean pretest scores of both science skills and knowledge of the two groups. Likewise, there was a significant relationship between the science skills and knowledge of the students exposed to open guided inquiry-based learning; however, there was no significant relationship between the science skills and knowledge of the students exposed to open inquiry-based learning. Patterns of inquiry skills were also manifested by the students as reflected in their science journals. Students who were exposed to both guided and open inquiry-based learning manifested conceptual understanding and factual recall as to their knowledge. Students in the guided inquiry-based learning group manifested science skills of analysis, predicting, interpreting graphics, and applying concepts while the students in the open inquiry-based learning group manifested science skills of applying concepts, analyzing, predicting, interpreting graphics, inferring, and synthesis/evaluation.
