<div>This study was a pretest and posttest experimental research design which set out to investigate the impact of an Instructional Model Ekwale Ada's Instructional Model on the application of biotechnology knowledge by high school students in the Anglophone Subsection of Education in Cameroon. That is to investigate whether students taught with the Ekwale Ada's Instructional Model for Biotechnology Knowledge Application exhibit a higher level of problem solving in biotechnology than students who were taught without the model traditional methods of teaching . The Ekwale Ada's Instructional Model for Biotechnology Knowledge Application was an instructional package which integrated Inquiry based learning Hands on , collaborative learning cooperative learning , Demonstrations, increase in the length of time learners are engaged in activities, Scaffolding and Remediation. The target population was Upper Sixth Science students in the Anglophone Subsection of Education in the North West Region, South West Region, and some displaced Upper Sixth Science students from North West and South West Regions into the Littoral Region for the 2018 2019 academic year. The researcher constructed a Biotechnology Application Test BAT in the form of a pretest and a post test. These tests contained three sections An MCQ section, a short answer section and a section in which practical activities were carried out.The indicator of biotechnology knowledge application was problem solving in biotechnology. For problem solving, the researcher created an inventory for the respondents to attend to which involved identification of a problem in the society which can be solved by a biotechnology product Description of the problem clearly Statement of multiple solutions to the problem Selection of the best solution to the problem Statement of the consequences of the best solution and usage of the best solution to solve the problem. The researcher created a five point inventory scale which ranged from excellent 5 marks Good 4 marks average 3 marks below average 2 marks and poor 1mark used to grade the problem solving activities. The students who were taught with the Ekwale Ada's Instructional Model for biotechnology knowledge Application experimental group scored higher in problem solving than those who were taught with traditional methods control group with a calculated independent t test value of 58.28 for the experimental group and 1.40 for the control group with a critical t value of 1.96 at 0.05 level of significance with 70 degrees of freedom. The sample of the study was 72 science high school students who offer biology 36 students for the experimental group and 36 students for the control group . Out of the 36 students from both the experimental and control groups, 18 were males and 18 were females making a total of 36 males and 36 females for the whole experiment. The sample was obtained from one government school, one mission school and one lay private school in each region. In the North West Region, 24 students were sampled 12 males and 12 females 08 from GBHS Bayelle, 08 from St Paul High School Nkwen and 08 from St Michael's High School . 24 students were sampled in the South West Region 12 males and 12 females 08 from GHS Buea, 08 from Baptist High School and 08 from Frankfils Comprehensive College Buea . In the Littoral Region, 24 displaced students 12 from the North West Region and 12 from the South West Region were sampled 12 males and 12 females 08 from GBHS Bonaberi, 08 from PHS Douala and 08 from Mother Theresa College Bonaberi Douala . Therefore the sample was 72 individuals 36 for the experimental group and 36 for the control group .The study was an experimental study in which a teacher made pretest was administered to both the experimental and control groups the students of the experimental group were taught with the Ekwale Ada's Instructional Model for biotechnology knowledge application treatment while those of the control group were taught without the model traditional methods of teaching . After the treatment, a teacher made post test was administered both to the experimental and the control groups. The experimental group was located in GHS Mamfe while the control group was located in Progressive Comprehensive High School Bamenda. One non directional hypothesis was stated in both the null and alternate forms. The null hypothesis was 1. There is no significant difference in problem solving in biotechnology between students taught with the Ekwale Ada's model and those who were taught without the model. The data for the pre test and the post test for the experimental group and control group were collected in the form of scores. The data was analysed using the SPSS Programme. The independent t test was used to find out the difference in means of the scores of the pretest of the experimental group and the control group and the difference in mean of the scores of the posttest of the experimental group and the control group. The null hypothesis was rejected and the alternate hypothesis was retained. They indicated that there was a significant difference in the means of the post test of the experimental group and the control group.The result of the study was 1. There was a significant difference in problem solving in biotechnology between students taught with the Ekwale Ada's Model and those who were taught without the model. The experimental group on whom the treatment was administered performed significantly better 58.28 than the control group 1.40 on whom the treatment was not administered.
