Abstract This study focused on enhancing biology students' achievement and attitude through Self-Regulated Learning Strategy in secondary schools in Delta Central Senatorial District. The study adopted the quasi-experimental pre-test, post-test control group design. Four research questions and four research hypotheses were formulated and raised to guide the study. The population of the study was all the biology students in senior secondary school II (SS II) in all the government-owned public secondary schools in Delta Central Senatorial District with an estimation of six thousand, four hundred and twenty-one students (6,421). A sample of two hundred and forty-five (245) senior secondary schools II students randomly selected from four (4) public mixed secondary schools was used for the study. The Simple Random Sampling Technique was adopted to draw the sample. The instruments used for data collection were the Biology Achievement Test (BAT) and Biology Attitude Questionnaire (BAQ). BAT and BAQ were validated by I Measurement and Evaluation and Biology teachers that have taught biology for more than ten (10) years. The reliability of BAT and BAQ were established using Kuder-Richardson formula 21 and Cronbach Alpha which yielded a coefficient of internal consistencies of 0.75 for BAT and 0.80 for BAQ respectively. Data were collected by administering the biology achievement test (BAT) and biology attitude questionnaire (BAQ) as pre-test and post-test. The data obtained were analysed using mean, standard deviation Analysis of Variation (ANOVA) and Analysis of Covariance (ANCOVA). The result shows that self-regulated regulated learning strategy significantly enhanced students' achievement in biology compared to the lecture method; there was no significant difference between the mean achievement score of male and female students taught biology using self-regulated learning strategy; there was a significant difference between the mean attitude score of students taught using self-regulated learning strategy compared with those taught with lecture method in favour of students taught using the self-regulated learning strategy and there was no significant difference between the mean attitude score of male and female students taught biology using self-regulated learning strategy. Based on the findings it was concluded that self-regulated learning strategy significantly enhances students' achievements and attitudes in biology. It was therefore recommended that biology teachers should adopt the strategy in teaching biology at the secondary school level and that biology teachers should be trained on how to use the skills of self-regulated learning strategy effectively.

Self-regulated learning is an effort to manage an individual’s learning. This research aims to 1) determine the strategy of self-regulated learning (SRL) based on problem-solving toward the learners’ learning outcomes and 2) determine the learning outcome improvement of the learners in learning by using the SRL based-problem solving. This research is quantitative research with quasi-experimental type and pretest-posttest control group design. The sampling technique was purposive sampling. The research population covered all in Senior High School (SMA 5) Yogyakarta. The samples were from the tenth graders of Mathematics and Science Program 3 as the control group and Mathematics and Science Program 1 as the experimental group. The data collection methods consisted of test and non-test. The analysis result were, the hypothesis test showed that the applied strategy influenced the learners’ learning outcomes and the learners’ learning outcomes had improvements with the N-gain average score of 0.590, categorized moderate. Keywords: Problem-Solving, Self-Regulated Learning Strategy, Simple Harmonic Motion
