Abstract—A combined quantitative-qualitative techniques and analysis was used in this experimental study involving eighty seven (87) third year high school students in MSU- Balindong Community High School during 2007-2008 calendar years. They were then distributed into three (3) groups: experimental group, control group and the pilot testing group. The respondent’s performance on HOTS questions, learning style, motivation style, creativity and interest were measured at the beginning and at the end of the study. Experimental group exposure on modular instructions using HOTS techniques involving multimodal strategies shows significant effect as compared to the control group. Most of them favored the HOTS techniques and modular instructions and they found it difficult yet more interesting, challenging and enjoyable. Index Terms—Critical thinking, creativity, and motivation, modular instruction, science education. I. INTRODUCTION Quantitative – qualitative techniques have been used to explore the effects of Higher Order Thinking Skills (HOTS) through modular instructions in teaching high school chemistry. As teacher, teaching is a profession of paramount importance both qualitatively and quantitatively important in serving education. So, we educator is obligated to not simply to bring out but to bring out the best among our students. A major issue faced by the educational system worldwide like in the Philippines case in particular is the low performance of the students in Science and Mathematics. Filipino students ranked 3rd and 4th from the bottom in math and science respectively on the two consecutive study conducted by the Third International Math and Science Survey TIMSS and TIMSS-R [1]. This low and alarming performance evidently indicate that Filipino students are not sufficiently trained to answer HOTS questions. Valdez [2]” research findings revealed that students in MSU-Balindong Community School were poor in HOTS questions in general science because apparently they are used to deal with simple recall questions only. Result of the System Wide Admission and Scholarship Examination (SASE) given by the Mindanao State Manuscript received April 20, 2013; revised June 30, 2013. A. Valdez, S. Mangorsi, D. Magdara, and M. Manalundong are with the Mindanao State University, Marawi City Philippines (email: anabelievillavaldez@gmail.com, sdmangorsi@yahoo.com.ph, dayamunmagdara@yahoo.com, maryammanalu@yahoo.com). V. Hambre is with the Department of Education, Iligan City Philippines (email: vdhambre@yahoo.com). University (MSU) showed that some of the high schools department in the university could not make even 1% of their students pass the said examination. The trend of MSU- Balindong performance is a case in point. In the year 2005- 2006, only seven (7) out of 70 graduating students who took the SASE examination were able to pass the said examination. In 2006-2007, only seven (7) out of 60 students who took the same successfully hurdled the test. The results of other examinations taken by graduating students of MSU- Balindong Community High School – i.e. DOST-SEI Scholarship Test – do not provide any consolation. None of the examinees passed the scholarship examination. To eradicate or just improve the quality education HOTS development among students is a pivotal technique for teaching instructions. HOTS are a creative program designed to enhance students learning style, creativity, interest, motivation and achievement. Research findings internationally, showed that HOTS produce learning gains of low-achieving students in grades 4-7 who demonstrate a great intellectual potential that they want to be successful in school. The right educational approach in the hands of a good teacher, and with the support of a principal can unleash this ability [3]. The evaluation made of the MSU- Balindong student’s performance serves the purpose of a needs analysis. The result points up the need for some intervention strategy that will lift the abilities of students to levels competitive enough to put them on a par with products of other schools, and enable them to pass qualifying and scholarship examinations. Thus, this study is timely and relevance to explore ways to improve student’s skills not only for short term goals but, more importantly, for life long and self –directed publication. II. RESEARCH METHODOLOGY A. Participant of the Study A total of 87 third year high school students in MSU- Balindong school year 2007-2008 participated in the study. They were grouped into three based on the matched – pairing of their previous grades in chemistry. The matched pair is then randomly assigned to respective groups by drawing lots. A total of 38 students are assigned each group in the experimental and control, while 11 students were assigned in the pilot testing of instruments to established validity and reliability. B. Research Design and Methods This study was a quasi – experimental using quantitative and qualitative research design.
