Abstract: Ethiopia is one of the countries that are making efforts to formalize the ASM (artisanal gold mining) sector by licensing individual miners, providing technical support for capacity building, and setting up basic infrastructure and facilitating formalized marketing of gold. The study area was in hectare where most the active mining and ecological land use and land cover were revealed. Because of this mining indigenous plants are degraded. Along the mining adjacent (rescued near to mining site), there was many indicator plants as the area is rich in various plant species. The present study was investigate on the spot that ecological impacts such deforestation, siltation, formation of trench and pits, top soil removal, water pollution and veldt fires were more significant. The government should enforcers the laws and regulations and promoter of mining development side by side putting ecological impacts mitigation measurements with stakeholders. Governments should enhance paying attention in supporting to financial resources and more incentives for conservation damaged ecosystems and create awareness and enforcing rules to create a healthy, sustainable and productive environment.

Abstract: This study investigated the effect of computer-assisted instruction (CAI) package on the performance of Senior Secondary Students in Zaria, Kaduna state, Nigeria. The study also examined the significance difference of retention achievement scores of students taught using computer-assisted instruction and the conventional lecture method. The population for the study was made up of all the 1800 SSII senior secondary schools chemistry students in Zaria Educational zone, Nigeria The sample consisted of forty senior secondary school students and was drawn from two secondary schools. Stratified random sampling was used to select the 40 students (20 males and 20 females) four research questions and four hypotheses were formulated, and tested at 95% confidence level. Chemistry Achievement Test (CAT) and Chemical Retention Test (CRT) made of 50 items of multiple-choice questions each were developed and validated for data collection. The Chemistry achievement Test (CAT) was administered to students as pretest-posttest and the Chemistry Retention Test (CRT) as a post treatment-test. The results of students were analyzed using t-test statistics to test the hypotheses. The result indicated that there is a significant difference between the performances of students taught using (CAI) package, and those taught using the conventional lecture method of instruction(t cal=7.77>tcrit=2.093 at P< 0.05). and also between the retention performance of students taught using (CAI) package, and those taught using the conventional lecture method of instruction tcal=3.95 >t crit=2.093 at P< 0.05 The result also showed there was no significant difference in the post-test performance scores of male and female students taught using CAI of package. Based on the findings it was concluded that the use of computer assisted instructional packages significantly improved the performance of students in chemistry. It was recommended that Computer-Assistant instructional packages should be encouraged for teaching and learning of chemistry.
