The music ministry is an invaluable ministry of the church. A church music ministry exists to develop a comprehensive music programme that ministers to all areas of the church’s life. An effective music ministry, therefore, provides the church with good music that members may use for worship, education and evangelism. The study adopts literary and theological approaches and engages pertinent scholarly literature. It discusses the value of music ministry to the congregation, the choir, the instrumentalists who play musical instruments and individuals who lead in the ministry. Furthermore, the study examines the various activities of the music ministry and factors that must be considered when organising a church’s music ministry. Finally, the paper discusses the criteria for enlisting leaders and workers for the music ministry. The study concludes that an effective music ministry must be put in place if the church music will be functional within the church.

The study examined the incidence of child labour in Rivers State and the implications for students’ educational development. Three objectives with corresponding three research questions were formulated to guide the study. The population of the study consists of 318 public senior secondary schools and 7,000 teachers in Rivers State Senior Secondary Schools board. The study adopted simple random sampling technique and made use of 30 public senior secondary schools and 300 teachers drawn from the three senatorial zones in Rivers State. The instrument used for the data collection was captioned “Child Labour in Rivers State and Implications for Students’ Educational Development Questionnaire (CLRSISEDQ)”. The reliability of the instrument was validated by two measurement and evaluation lecturers in the department of educational foundations in Rivers State University, while mean score was used to analyze the research questions and tables were used to organise the data. The result of the findings revealed that to a high extent various forms of child labour exist among students in public senior secondary schools in Rivers State. Also, to a high extent many factors are responsible for child labour among the students and finally to a high extent child labour impact negatively on the students and consequently, the educational development of the state. Based on the findings, it was recommended among others, that government should mandate the law enforcement agencies to arrest and prosecute culprits of child labour and parents should give birth to the number of children they can properly cater for.

The study examined the impact of concept map and concept test on critical thinking ability of undergraduate students of University of Port Harcourt, Rivers State, Nigeria. A sample of 307 fourth year students from three departments in the university was chosen using simple random, purposive and accidental sampling techniques. These students were assigned to three different groups, two experimental treatment groups and one control group. One group was treated using concept mapping, the second group was treated with concept test while the control group received the conventional method of assessment. To guide the study, two research questions and two null hypotheses were developed. The study adopted a quasi-experimental research design by pretest, post-test non-equivalent control group design. The pre- and post-tests data were collected using an adopted 52 item instrument named Cornell Critical Thinking Test (CCTT) Level Z. It is a 3- option (A-C) multiple-choice test with 7 subscales measuring induction, deduction, value judgment, observation, credibility, assumption and meaning. Using Kuder-Richardson 20 formula (K-R20) their internal consistency estimates were 0.81, 0.76, 0.66, 0.71, 0.70, 072 and 0.68 respectively for the subscales, while internal consistency of 0.74 was obtained for the total scale. Data were analyzed using mean, standard deviation, paired t-test, and analysis of covariance. The results obtained indicated that concept map, concepts test and the conventional assessment method independently had positive impacts on critical thinking ability of the students. However, concept test was the most effective, followed by concept map and lastly the conventional method. On the basis of the findings, it was recommended amongst others that school administrators, curriculum developers and faculties should update their curricula by integrating concept test and concept map assessment methods in their instruction as this can improve critical thinking ability of their students.

The progression in science and technology has increased human survival on earth. Man has witnessed a great and extraordinary progress in technology, which our lives depend on it for its survival. These developments come in many dimensions as we have in medicine, bio-technology, security, education, information and communication, economy, artificial intelligence, etc. Charles Hartshone argued that “Science and technology fantastically increase the number of those whom that best is available. Secondly, since science and technology allows a great number of people at least a marginal existence [1].” In addition, as Charles quoted Ortega y Gasset, Science and technology makes kingly luxuries commonplaces for large numbers of people [2].” In all these developmental success, Ethics has critical intervention to act like Plato’s rational parts of the soul which Plato compared to as element of a Charioteer to the two horses controlled by the Charioteer. One part of science and technology is good which I have stated above while the other horse is bad (the appetitive element). While all can enjoy and see the development and success of science and technology – the good horse which is easily driven according to the directions of the Charioteer, the bad horse tends to obey the voice of sensual passion. So this paper among all, argues that science and technology usage must not be totally right. Its usage must be controlled by Ethics by not destroying those that make use of (science and technology) it, even as it has positive usage. I shall discuss the nature of science and technology using the arguments of Walter Rodney on science and technology and nature of ethics. The theoretical framework used shall be that of Platos’ on the need to control the bad part (horse) of science and technology.

Learning motivation is one of the important factors that affect students' mathematics learning. It is one of the challenges that junior high school mathematics unit teaching faces to effectively improve students' learning enthusiasm in mathematics unit classroom. ARCS motivation model is an important theoretical model that focuses on the relationship between instructional design and students' motivation, and can effectively stimulate and maintain students' learning motivation in subject teaching. Based on this, this study applies ARCS motivation model to junior high school mathematics big unit teaching classroom, and discusses the strategies of motivating junior high school mathematics big unit teaching motivation under ARCS motivation model, that is, effective introduction of teaching, selection of related content, phased task driving and multiple feedback evaluation; The teaching mode of junior high school mathematics big unit under ARCS motivation model is constructed, that is, analyzing the demand and setting the goal; Generate strategies and integrate teaching; Implement strategy and encourage design; Unit evaluation and evaluation results. This research is an in-depth exploration of cultivating students' autonomous learning ability in large-scale unit teaching, and is committed to improving the teaching effect of large-scale units and implementing the new requirements of compulsory education curriculum standards.
