Abstract-The researcher investigated the effect of simulation method on students' interest in programming language in secondary schools in Enugu education zone of Nigeria using quasi-experimental design. The instrument for data collection was pretest -posttest non equivalent control group. The population for the study comprised all senior secondary school class 2 (SS2) science students in a single sex school in Enugu Education Zone of Enugu State. Data were collected from a sample of 225 students selected from four secondary schools two boys' schools and two girls' schools. A reliability coefficient of 0.89 was obtained from the instrument through test retest. Mean and standard deviation scores were used to answer the research questions, while two-way analysis of Covariance (ANCOVA) was used to test the hypotheses at 0.05 level of significant. The findings show that students taught using simulation method achieved higher than those taught with traditional method. It was recommendations that ministry of education should revisit the instructional materials used in teaching.

Critical, time-bounded, and high-stress tasks, like incident response, have often been solved by teams that are cohesive, adaptable, and prepared. Although a fair share of the literature has explored the effect of personality on various other types of teams and tasks, little is known about how it contributes to teamwork when teams of strangers have to cooperate ad-hoc, fast, and efficiently. This study explores the dynamics between 120 crowd participants paired into 60 virtual dyads and their collaboration outcome during the execution of a high-pressure, time-bound task. Results show that the personality trait of Openness to experience may impact team performance with teams with higher minimum levels of Openness more likely to defuse the bomb on time. An analysis of communication patterns suggests that winners made more use of action and response statements. The team role was linked to the individual's preference of certain communication patterns and related to their perception of the collaboration quality. Highly agreeable individuals seemed to cope better with losing, and individuals in teams heterogeneous in Conscientiousness seemed to feel better about collaboration quality. Our results also suggest there may be some impact of gender on performance. As this study was exploratory in nature, follow-on studies are needed to confirm these results. We discuss how these findings can help the development of AI systems to aid the formation and support of crowdsourced remote emergency teams.

Abstract-Many households in Enugu depend on water sourced from municipal water system for domestic use, especially for drinking purposes. Unfortunately, this source is not safe enough for drinking primarily due to poor water distribution network. As water travels from the Point of Treatment (POT) to the Point of Use (POU), it comes in contact with numerous contaminants via broken and rusty pipes. This study proposes a system that reduces or totally eliminates pollutants from domestic water at the point where it is used. . By channelling water through a system of activated carbon filter, these pollutants are removed at POU. The system is made-up of a reservoir, filter and dispenser subsystems. Water enters the reservoir from the POT and from where the filter is fed. The output Water from the filter enters another reservoir from where it is dispensed. These processes of storage, treatment and dispensing are fully automated using a microcontroller chip to ensure efficiency and convenience. This study will be beneficial to the Ministry of water resources and the general public.
