 Aim of this study is to determine the effect of environmental education program integrated into preschool education aged between 48-66 months on children’s mental model development about “environment” concept. Triangular mixed design was used in this research. Quantitative dimension of the study was carried out with quasi-experimental design with control group and qualitative dimension of the study was carried out with using phenomenological method based on social constructivist philosophy. Study group of the research consisted of 52 children from experimental and control groups. Statistically significant difference was observed in the scores of children in the experimental and control groups from DAET-R (U= 44, z= -5.44, p= .000, r= .75). Mental model development about environment of the majority of the children from the experimental group reached to an expected level. However, no development was obtained in the mental model development of the children in the control group. Results also showed that 80.8% of the children from experimental group defined environment as a place which people, animals and plants live together and the amount of the children from control group who defined environment similar to this level is 26.9%. In addition, there was no significant difference in the total pre-test and post-test DAET-R scores of children from the control group (z= -1.401, p > .05) and significant difference was observed in the pre-test and post-test DAET-R scores of children in the experimental group in support of post-test results (z= -4.126, p < .05).

In Bangladesh some researchers have done several studies to find the correlation of simple diffuse goiter with arsenic level but no one conducted any study to find the differences of urinary iodine, urinary arsenic, radioiodine uptake, the thyroid stimulating hormone (TSH) and free thyroxin (FT4) levels between goitrous and non goitrous. That is why, in this research an attempt has been made to compare the urinary iodine, urinary arsenic, radioiodine uptake, TSH and FT4 levels between experimental group with simple diffuse goiter and healthy control group. In this study another purpose has also been made to find the associations between different pairs of variables for both experimental and control group. In this study we have tried to find the impacts of arsenic level on simple diffuse goiter. This is a case-control analytical study. The study is carried out in the Institute of Nuclear Medicine and Ultrasound, in collaboration with the thyroid out patient department of Bangabandhu Sheikh Mujib Medical University. A total of eighty five (85) subjects are included in the study. Among the 85 subjects, a sample of forty five is considered for experimental group with simple diffuse goiter and another sample of forty is considered for healthy control group without any thyroid disease. From the experimental results it has been found that, the arsenic levels, FT4 and radioiodine uptake levels at 2 hours between the experimental and control groups are significantly different but the urinary iodine levels, TSH levels and radioiodine uptake levels at 24 hours between the experimental and control groups are not statistically different. From the experimental results it has also been found that there is significant differentiation between experimental and controls groups in respect of association between different pairs of variables. In this study, another significant finding is that iodine deficiency is not only the factor of causing simple diffuse goiter, but arsenic level is also one of the most important factor of causing simple diffuse goiter.

This study aims to investigate the possible effects of peripheral learning on elementary EFL learners’ grammar improvement: the case of prepositions of time and place. Two elementary classes were selected as experimental and control groups. Before beginning the treatment, a grammar test was administered to both the groups as a pre-test. Then, as treatment, the experimental group was exposed to realia, pictures, posters and texts, while the control group was not. After term-long treatment of 10 weeks, the two groups received the same grammar test as post-test. The results of t-test showed that the experimental group improved their grammar ability, i.e., knowledge of prepositions of time and place more than their friends in the control group. The finding of the study may open an optional path for teachers to include some peripheral materials in their teaching environment to further invest on unconscious learning abilities of the students.   Keywords: Peripheral learning, reposition of time, prepositions of place, grammar.
