ABSTRACT
This study looked at how students' achievement in Physics in senior secondary school one was affected by explicit problem solving instruction. A quasi-experimental pre-test-post-test design was used. The study involved two student groups: the Experimental Group and the Control Group. While the control group did not receive formal teaching on problem-solving techniques, the experimental group did receive such training. Utilizing the Physics Achievement Test, data were gathered and analysed using descriptive statistics and ANCOVA. The findings show that providing clear guidance on how to solve problems improves students' achievement in physics. According to this study, providing clear instructions on problem solving was beneficial for both males and females. To improve students' achievement in Physics, physics teachers should provide clear guidance on problem solving to their students.

ABSTRACT
Maintaining customer loyalty is the main focus for fashion product sellers. Many factors influence customer loyalty. The aim of this paper is to determine the influence of customer income, price discounts, and fashion product shopping lifestyle on customer loyalty. The objects of this research are factors that influence customer loyalty, namely customer income, product discounts and customer lifestyle. The data scale in this research is an ordinal scale. The number of respondents in the research was 200 customers. We use multiple regression models to determine the influence of independent variables on the dependent variable. The results of this research show that income, price discount and lifestyle have a significant influence and are positively related to customer loyalty, both simultaneously and partially.

ABSTRACT
The article discusses the Family Planning (FP) program’s wide spread evaluation by the Program Evaluation Organization (PEO) of the planning commission from 1963 to 1969. The article brings out the Knowledge, Attitude & Practices (KAP) concept given by the PEO. The concept is still used by the large scale surveys like National Family Health Surveys since the 1992-93 period. The KAP approach was given by the FP but it is being used regularly to evaluate other programs as well. After the KAP, the concept of Rapid Anthropological Surveys (RAP) also came up to monitor & evaluate programs. Subsequently, the concept of Culture, Attitude & Practices (CAP) also came to be used to assess programs.

ABSTRACT
The study examined family types and school types as determinants of in-school adolescents’ risky sexual behaviour in Yenagoa educational zone of Bayelsa State, Nigeria. The study adopted a correlational survey research design to determine between family types and school types as determinants of in-school adolescents’ risky sexual behaviour in Yenagoa educational zone of Bayelsa State, Nigeria. The population of the study consisted of thirty five (35) public secondary schools in Yenagoa educational zone of Bayelsa State, Nigeria with a total of eight thousand, nine hundred and thirty nine (8,939) SS1 and SS2 students. Twenty nine (29) private schools with a total of three thousand four hundred and eighty four (3,484) students in private secondary schools in Yenagoa educational zone of Bayelsa State, Nigeria. The simple random sampling technique was adopted to select five (5) public secondary schools and five private secondary schools in Yenagoa educational zone of Bayelsa State, Nigeria. The sample for the study consisted of forty (40) SS1 and SS2 students from five (5) selected public schools and five (5) selected private schools in Yenagoa educational zone of Bayelsa State, Nigeria with a total sample size of four hundred (400) in-school adolescents. A self-designed instrument titled family types and school types on adolescents sexual behaviour questionnaire (FTSTASBQ) was used to collect data for the study. The instrument was validated and yielded a reliability coefficient of 0.86. The research questions were analyzed using mean and standard deviation, while Spearman rank was adopted in analying the stated hypotheses. From the analysis, the study found out that family types and school types have significant relationship with adolescents’ risky sexual behaviour in Yenagoa educational zone, Bayelsa State.
