Development and validation of modules in teaching Earth Science for Senior High School students [manuscript] / Rossel Gille B. Garcia.

Includes:Bibliography.

This research endeavored to develop a module on Earth Science to enhance students' least-learned topics. Through the use of ADDIE model, the researcher was able to develop a module. The processes undergone were the analysis phase and the design phase, both of which were part of the planning stage, while for the development phase, the processes were the creation and execution of the plans. Tha last phases were the implementation and evaluation phase. The module also went into validation of its content and language used. All of the six (6) Earth SCience teachers of Tomas del Rosario College strongly agreed that the modules' Learning Competencies, Instructional Design and Organization, Instructional Quality, Assessment, and Readability can hone students' differences and can be used as instructional materials for students' learning, which reflected an average mean of 4.80 or strongly agree. Moreover, in terms of language validation, all of the six (6) Earth Science teachers Tomas del Rosario College strongly agreed that the modules' Coherence and Clarity of Thought, Spelling and Punctuation, and Consistency in Style can hone students' differences and can be used as instructional material for students' learning, which was drawn from the average mean of 4.77 or strongly agree. However, in terms Grammar and Syntax, the respondents moderately agree that some of the contents has grammatical errors, which was clearly shown by the average mean of 3.11 or moderately agree. the developed module can also be tested with other group of respondents to know the effectiveness and usability of the modules. Future researchers can distribute the modules and test their level of acceptance and level of effectiveness on another group of respondents. Also, experimental design can be used in order to further test the validity of the modules.
