The study investigated the relative effects of downside resolution and construct mapping ways on student’s action of some environmental ideas in senior lyceum chemistry. The study additionally wanted to understand the moderating effects of student’s gender and verbal ability on student’s action in environmental ideas. The study adopted pretest, post-test quasi-experimental style. The population was created of all senior lyceum three students within the three legislator districts of Ekiti State. The sample consisted of scholars of that were males and were females. Two instruments were utilized in the study. These were Environmental Education action takes a look at and Verbal Ability takes a look at. Information was analyzed victimization ANCOVA and t-test. The results disclosed that there's a big distinction within the post take a look at many subjects exposed to problem-solving, construct mapping and traditional ways. The study additionally showed that there's a big distinction within the action many male and feminine subjects exposed to the treatments. It absolutely was additionally pictured that subjects of high verbal ability performed higher than those of low verbal ability once exposed to downside resolution and construct mapping ways. On the idea of those, it's so counseled that chemistry academics ought to adopt the problem-solving and construct mapping ways within the teaching of environmental aspects of chemistry to their students. To impart directions in science keeping visible the dynamic nature of learner, subject and atmosphere there's imperative got to total some artist approach that should specialize in purposeful learning also-Concept Mapping is such response during this regard that, being a two dimensional technique for hierarchal arrangement of ideas, sub ideas and their relationships, represents the psychological feature structure of learner with relation to the involved ideas in context.

Many countries of the world and individuals are expressing worries about the rapid deteriorating state of the environment as a result of neglect, ignorance and hazardous sociocultural practices. Serious concern with environmental issues in Nigeria is a relatively recent event while global concern about the environment has been growing for several decades in developed parts of the world as a result of the perceived impact of rapid sociological, technical and scientific advancement Beissner (1992). However, the awareness of environmental problems has also been gaining ground within developing countries as manifested in their attempt at reducing poverty and disease which are themselves forms of environmental degradation. Almost all human activities pose serious threats to the environment, the most important of which are the use of pesticides and herbicides, the disposal of solid wastes, air pollution, water pollution, radiation and radioactive substances and over population (Heller et al., 1992). The European Union (EU) countries agreed to reduce greenhouse gas emission levels by the year 2020 and to make renewable sources of energy, such as solar and wind power account overall EU energy consumption by 2020.
However, in Nigeria, the non-governmental organizations have been the moving spirit behind most of the environmental awareness programme and conservation projects. Despite the combined efforts of various non-governmental organizations, the environmental degradation still persists Johnstone (1993). The dangers associated with environmental problems in Nigeria have been identified as management, unethical practices and over population. Based on these reasons, the environmental problems have become a priority on the world’s political agenda starting form 1990. There have been concerned efforts in Nigeria to integrate environmental education into core curriculum of the education system (Reif et al., 1976). This came into fruition via the national conservation foundation and ministry of education that drew up a national conservation education strategy which adopted Environmental Education as a module for the new citizenship curriculum for secondary schools. In Nigeria formal school system, environmental education is taught as a part of other subjects such as Integrated Science, Chemistry, Physics, Biology, etc. The Nigerian Educational Research and Development Council (NERDC) have made spirited efforts to infuse environmental education concepts in many subjects in the junior and senior secondary school curricula.
Concept maps help students visualize various connections between words of phrased and a main idea. Various types of concept maps exist some are hierarchical while others connect information without categorizing ideas. Most concept maps comprise of words of phrases surrounded by a circle or square that connect to one another and ultimately back to the main idea through graphic lines. According to Hyerle, these lines help students to negotiate meaning as the read and make the meaningful connections between the main idea and other information. Lovitt and Horton asserted that concept maps have been shown to support struggling readers by building off of student’s prior knowledge and asking them to reflect on their understanding while reading. The maps can be applied to any subject matter at any level within the subject Stoyanov & Kommers (2006).
From the results obtained, it is revealed that there is a significant difference in the post test scores of subjects exposed to Problem-solving, concept-mapping and the Conventional strategies. It is also depicted that there is a significant difference in the achievement scores of male and female subjects exposed to the treatments. Here, male subjects in the concept mapping performed better than their female counterparts while the female subjects performed better than their male counterparts in both the problem-solving and conventional strategies. Furthermore, the study reveals that subjects of high verbal ability performed better than those of low verbal ability when exposed to problem-solving and concept-mapping strategies.
