Introduction

1.1 Background of the study

Physics as one of the branches of science is a “sine qua non” for economic and technological development of any nation. Its role to scientists, engineers, chemists and other practitioners of physical and biological sciences cannot be over-emphasized. The discoveries in communication industries, the automobile and transportation industries, the field of health and medicine and many more make use of the concepts of physics. Physics is, therefore, very much required for the aforementioned scientific and technological national development. But unfortunately, it has been noted by some researchers that physics achievement at secondary school level has been low (Kalijah, 2003). This low achievement has been attributed to many factors such as method of teaching. When inappropriate teaching method is employed in teaching, consequently the achievement by the students in that subject area is bound to be low. Also Okoronka (2004), Okoli (2006) and John (2009) in their different studies observed that factors contributing to low achievement in physics and in other science subjects may be linked to the use of instructional strategies which have not totally incorporated learners’ previous knowledge. Some physics educators such as Okoli, John &Adeyomo (2003) have recommended some instructional methods over the years to curb the problem of under-achievement. It is against this background, therefore, that the researcher sought for an appropriate teaching method that will engender students to achieve higher in physics. Thus, this study is undertaken to investigate the effect of constructivist teaching strategy in Dutsin-ma metropolis.

According to Mbajiorgu (2003), the constructivist view tends to encourage learners to interpret and incorporate new information into the already existing schemata. In constructivist classroom,new ideas are constructed based on comparison with current and previous knowledge.

Here, the students interpret things they see and experience by comparing similarities and differences to ideas they already have. In constructivist classroom environment, learners are the central focus. The interaction is among the learners and the teacher’s guide them. As the students share their experiences with the group, they learn from each other. This is in contrast with a traditional classroom where lecture method is used. In constructivist classroom, the students’ active participation is encouraged and this allows the instructor to see many aspects of students’ capabilities such as in the areas of communication and problem solving skills. Some examples of activities that encourage constructivist learning are experimentation, research projects, field trips, class discussions, among others. The constructivist method, which is student-centered, may change the trend of achievement in Physics. (Constructivist teaching method is a method which holds that knowledge is personally constructed and reconstructed by the learners based on their prior knowledge and experience. Akinbobola and Folasade (2009) explain that constructivist learning is based on the cognitive theory of learning, which holds that learning takes place as a result of intuition.This implies that individuals intuitively bring a number of events together to serve a purpose in knowledge construction. Gray (2011) notes that constructivist teaching is based on the belief that learning occurs as learners are actively involved in a process of learning and knowledge construction, rather than passively receiving information. Constructivism therefore is a set of beliefs about knowing and learning that emphasizes the active role of learners in constructing their own knowledge with new experiences.

D’costa (2010) opines that Constructivist teaching fosters critical thinking and creates motivated and independent learners.It can be inferred from the foregoing definitions that the constructivist method is a method of teaching that encourages the students to be active participants in the classroom. It also helps them to construct their own knowledge based on the previous learning. It means that learners are actively involved in the knowledge construction and not mere spectators. This reveals that there is no dull moment during the knowledge construction. In this method of teaching, the teacher serves as a guide and the learner takes the responsibilities of constructing his or her knowledge based on his or her previous experiences. The method is learner centered. In teaching physics, the constructivist teaching method will offer the students the opportunity to construct ideas, skills and knowledge based on their previous experiences. The theoretical framework of constructivism holds that learning always builds upon prior knowledge that a student already has.

This is because all learning is filtered by pre-existing schemata. Achor (2007) is of the view that the learning style of the constructivist student is cognitively independent of the teacher, since he/she is self-driven, self-motivating and self-inquisitive. The teacher acts as a facilitator and agent of learning, who evaluates by emphasizing understanding while the students are engaged in problem solving. Furthermore, guided discovery, anchored instruction and social constructivism are some aspects of constructivism.

Constructivist teaching method has been found to be efficacious in teaching science and other language area like English. Eze (2007) conducted a research on the effect of constructivist teaching method on student’s performance in physics  in Enugu education zone and the results shows that students in the experimental group that were taught with the constructivist instructional method achieved higher than those taught with lecture method in the control group,

AlsoUkozor (2011), conducted a research on effect of constructivist teaching strategy on senior secondary school students’ Achievement and self- efficacy in physics in Ibadan. He found that constructivist teaching strategy had significantly better effect on students’ achievement and self- efficacy in physics.Furthermore, Ursula (2014) conducted a research in Abiastate on the effect of constructivist teaching model on SSS physicsstudent’s academic achievement and interest. He found that student taught physics using constructivist teaching methods than their counterpart taught using conventional method and also have higher interest in physics. This study is carried out on constructivist teaching strategy on Physics secondary students’ achievement in waves and optics conceptsin Dutsinma metropolis

Gender isalso a variable this research is measuring and so many researches have been conducted on gender. Among which is a  research conducted by Afolabi and Akinyemi (2009) on Constructivist Problem Based Learning Technique and the AcademicAchievement of Physics Students with Low Ability Level in NigerianSecondary Schools in Taraba state and the findings indicated that there was no significant gender difference in the performance of students taught with constructivist strategy and their counterpart, also researches by Doris (2016),Obiekwe (2008) &Akinbobola (2010) on constructivist teaching strategy in Nigerian secondary schools found out that there were no significant gender difference in the performance of students taught with constructivist strategy and this is why the researcher intends to find out the effect of Constructivist teaching strategy in senior secondary school students’ achievement in waves and optics in Dutsinma metropolis.

1.2 Statement of the problem

Many teachers handling science subjects in most of our secondary schools specialize in science, not in science education Omosewo (2009). Therefore, these teachers lacked appropriate instructional strategies for teaching and often used lecture method. Science education in Nigerian schools is faced with many challenges; one of such challenges is the out-of-field teaching. This is when a teacher is assigned to teach subjects for which he or she has not got adequate training and qualification (Ingersoll, 2002). These categories of teachers need a change of teaching method as most of them teach by the lecture- based instruction. This lecture method has been criticized for lack of effective interactive approach The performance of students in science subjects in the resent time has not been very good (Erinosho, (2013); Crouch, Watkins, Fagen& Mazur, (2007). The concern for every Nigerian is what causes poor performance. Among the causes of poor performance is the teachers’ method of teaching (Wanbugu, Changeiywo&Ndritu, (2013); Oladejo, Olosunde, Ojebisi&Isola, (2011)). Based on this, it is important to review the different type of teaching methods in science education, their disadvantages and the need for a shift of paradigm.

The teaching of physics in Nigerian secondary schools has been with the use of traditional method of instruction. However, the achievement of student’s in the subject especially at SSCE level has consistently remained poor. This implies that student’s academic achievement from the use of this method of teaching is not supportive and encouraging. Meanwhile, the introduction of constructivist teaching method into secondary school classroom in other countries has proved to be effective in improving teaching and learning process. This study therefore determined the effect of introducing constructivist teaching method on students’ learning outcome on senior secondary school students’ achievement in waves and optics in Dutsinma metropolis.
