Ratio of head circumference and chest circumference were 0.96 and 0.97 respectively, and indicated that no asymetric growth retardation among two groups. The head circumference among children of mother with maternal goiter was 46.35 cm compared with 46.05 cm for children of mother without maternal goiter. The growth rate of children of mother with maternal goiter was 278.33 gram and 264.16 gram for children of mother without maternal goiter. Mean of birth weight among children of mother with maternal goiter was 3.02 kg and 2.96 kg for children of mother without maternal goiter. Median of urinary iodine excretion amongchildren of mother with maternal goiter was 404 μg/L and 506 μg/L for children of mother without maternal goiter. The observed variables were iodine status of children, the growth parameters such as body weight gain, nutritional status, head circumference, chest circumference the development parameters such as motor miles stone, and score of pre screening questionnaire for development (KPSP).The result of the study indicated that prevalence of maternal goiter was 48.21%, prevalence of iodine deficiency among under two years children was 8.93%. The Study was conducted in Banyu Arang village, Ngoro Sub distric, Jombang Distric, because this village was categorized as severe endemic goiter area.

The research design was retrospective cohort. Based on these results, it is can be concluded that the development of learning module based on Science Process Skills were valid and practical.The objective of this research was to study the growth and development pattern of under two year age children of mother with maternal goiter. The practicality of this product was obtained by teachers responses with the value 90.35% (very practical) and students responses with value 94,29% (very practical). The result from expert validators showed that the module is suitable to use because the validity of this product is 4.74 (valid). Assesment of this module was evaluated with two expert validators. The components of science process skills that used in the module which are observing, communicating, measuring, predicting, and concluding.

The stages of ADDIE are analysis, design, development, implementation, and evaluation.

The development of this module used ADDIE models. The type of this research is Research and Development (R & D). Abstract: The aim of this research is to develop a learning module based on Science Process Skills in growth and development for XII grade of senior high school which is valid and practical.
