ItemDynamics of Conceptual Change in the Biology Classroom: A Multidimensional Interpretive Framework( 2001)This study investigated high school students’ conceptions of genes during a two-week study on inheritance using a multidimensional framework of conceptual change from ontological, socially effective and epistemological perspectives. Specifically, the study attempted to establish students’ ontological perspective of the concept of the gene, investigated conceptual change about genes from the students’ cognitive framework, and then examined this ontological conception from both social/affective and epistemological perspectives. The sample for the study consisted of three high school biology classes in two different schools in Zamboanga City. These are two public urban nonscience high schools with special science classes and a private nonsectarian coeducational science high school. The three classes consisted of mixed-ability second-year high school students (ages 14-15) who do not study genetics previously and who were taught by experienced biology teachers. The research design is qualitative-quantitative. The data were gathered through student worksheets given before and at the end of the unit, observations of lessons, videotape and audiotape recordings of classroom discourse and detailed student interviews at the end of the unit.

ItemEnhancement of Problem-Solving Skills in Chemical Equilibrium Through a Modified Network Approach( 2002)This is a study on the effectiveness of the modified network approach on the enhancement of problem-solving skills of first-year college students in chemical equilibrium. Ashmore et al.’s network approach was modified using diagramming and scrambling exercises which were aimed at developing and training students in combinatorial and correlational thinking skills which students can use to enhance their problem-solving skills. A comparison of scores in three problem-solving tests was used to measure the effectiveness of the modified approach. Qualitative analysis of the solutions of students to the problem-solving tests was used to characterize the first-year chemistry problem solvers. A rubric scoring scheme was developed to identify the problem-solving skills demonstrated by problem-solver as it was equated to scores obtained in the problem-solving tests. The study also characterized the first-year problem solver before and after treatment through a qualitative analysis of the students’ solution papers, the protocol of small group discussions, interviews and think-aloud sessions. Students in both experimental and control groups were administered Lawson’s Classroom Test of Scientific Reasoning to determine their cognitive level before and after treatment.

ItemPractical’s for Enhancing Conceptual Understanding in Inquiry Skills( 2002)This study attempted to determine the effectiveness of practicals in enhancing conceptual understanding about cellular respiration in relation to the functioning of six body systems and enhancing inquiry skills. The study was quasi-experimental in research design and involved forty First Year 1-A and 1-D BEED students enrolled in Natural Science 102 during the Second Semester of AY, 2000-2001 at West Visayas State University in Iloilo City. A pre-and post-instruction conceptions test, inquiry skills test, concept maps and interviews served as sources of data for the study. Ten case students from the experimental and control groups, respectively, were also selected for qualitative aspect of the study. The intervention consisted of seven practicals that dealt with cellular respiration, the functioning of six body systems in relation to cellular respiration and the changes that occur during vigorous activity or emergency. Students also analyzed the practicals requiring the use of eight inquiry skills, namely, identifying the problem, formulating hypothesis, designing a procedure to test the hypothesis, interpreting data, recording data in a form that facilities correct interpretation, seeing patterns and relationships in a set of data, judging adequacy of data and inferring. They also answered questions in relation to the procedure in the practical to enhance their conceptual understanding.

ItemLearning Transfer and Durability in College Biology Students Via Computer-Assisted Instruction( 2002)This study primarily aimed to identify students’ misconceptions/alternative conceptions and their sources; the effect of computer-assisted instruction on the Human Circulatory System (HCS) on students’ conceptual change, learning transfer and durability of learning; and students’ motivational beliefs and response to anomalous data as factors influencing conceptual change. The hypotheses that there were no significant differences in students’ conceptual change, transfer of learning and durability of learning between the computer-assisted instruction (CAI) group and the traditional instruction (TI) group were tested. The respondents of the study were on the section of first-year BS Development Communication students. The class was randomly divided into the CAI group and the TU group. The CAI group underwent instruction in the HCS using CAI while the TI group was taught using the chalk and board method. The study was divided into two phases: (1) design and development of HCS-CAI); and (2) tryout of CAI.

ItemRelationship of Selected Factors to Science Teaching Efficacy and Classroom Performance of Biology-Student Teachers( 2002)This study investigated the science teaching efficacy of 101 biology student-teachers of selected institutions in Bicol and the Visayas that offer Bachelor of Secondary Education Major in Biology. It also identified the internal and external factors that affect such efficacy and established the patterns of relationships between science teaching efficacy and classroom performance. Instruments developed to gather data were the following: (1) survey questionnaire, (2) interest and attitude scale, (3) science teaching efficacy scale, (4) achievement test in biology, (5) process skills assessment test, and (6) standards of classroom performance. Student-teachers filled up the respondent’s datasheet, the interest and attitude scale, the survey questionnaire and the science teaching efficacy scale. Then they took the achievement test in biology and the process skills assessment. Then dean or the principal, the critic teacher and the researcher evaluated the student-teacher scheduled to teach during the day using the standards for classroom performance. The actual teaching was recorded on videotape. Multivariate Analysis of Variance (MANOVA) was used to analyze data and establish relationships. Qualitative analysis was used to find patterns in science teaching efficacy and classroom performance. For this, data was taken from eight cases. Three cases were presented/studied as samples.
