Therewith, 165 teachers and 9 principals were involved. Analysis shows that 84(52.5%) of teachers agreed that their planned lessons contain learner-centered activities, and 41(25.6%) strongly agreed. Teachers' responses on My principal ensures that I use teaching aids in teaching, 101(63.1%) agreed, 32(20%) strongly agreed, 12(7.5%), and 9(5.6%) disagreed and strongly disagreed, respectively. Regarding teachers' use of modern methods of teaching, 7(77.8%) of the principals agreed, and 2(22.2%) strongly agreed. Principals' responses on Teachers in my school ensure that students gain mastery of the content of instruction reveals 6(66.7%) of them agreed, 2(22.2%) were undecided, and 1(11.1%) strongly agreed. On teachers keeping records of vital information of instruction, most principals are positive as 4(44.4%) and 4(44.4%) agreed and strongly agreed, respectively; 1(11.1%) undecided. Principals submitted Teachers keeping records of student’s assessment 5(55.6%) as agreed, 3(33.3%) strongly agreed, and 1(11.1%) undecided. Pearson Product Moment Correlation shows a very high positive correlation between instructional supervision and the appropriateness of teaching methods used in the study area; likewise, there is a moderate positive relationship between instructional supervision and teacher record keeping. Effective supervision of secondary schools is needed for teacher effectiveness in schools in Tambuwal local government area and Sokoto state, Nigeria

Abstract

Nitrate, cyanide, and flavonoids are among the chemicals that threatens hormones especially the thyroid gland and in turn affecting the body. Their presence in tobacco and cigarette shall be determine to inform the public. The objective of this work was to determine the extent of nitrate, cyanide, and flavonoids in soil and tobacco from Sokoto, Nigeria using standard methods. The results determined by this work indicated varied levels of goitrogens (cyanide, nitrate, and flavonoids) present in soils and tobacco leaves grown in three different points within Sokoto state, Nigeria (namely, Sokoto city, Gwadabawa, and Illela). 100.21±6.12 -705.10±4.60ppm, ppm 136± 6.10-170.30±3.36ppm, 7.10±0.3-17.0±0.11ppm are range values of cyanide, nitrate, and flavonoids respectively obtained in soils in Sokoto state. Likewise, 90.0±2.16-500.0±1.3ppm, 70.11±3.9-120.0±10.3ppm, 6.2±0.5-25.11±0.05ppm are the ranges of cyanide, nitrate, and flavonoids respectively determined in tobacco leaves in Sokoto state, Nigeria. There exist elevated levels of the goitrogens in soils and tobacco in Sokoto, therefore, risking the consumers and non-consumers to iodine deficiency.
