briefly describe their studies’ Independent Variable, Dependent Variable and mea

briefly describe their studies’ Independent Variable, Dependent Variable and measures. Students will describe in full their proposed research design and write step by step procedures for conducting their research. The writing of the procedures should be such that it could be easily replicated. Students will also discuss how they plan to ensure internal validity of their research. Describe fully why your study meets the criteria for research, and not just intervention with data collection.
Research Study below:
Research Question: Can scaffolding improve reading among grade 2 early childhood learners with low reading achievement? 
The above research question can be studied using a single case design research because it targets a specific population. Single case design takes an evaluative approach to determine the success of a treatment or an intervention on a selected group, individuals or community so as to give evidence about the effectiveness of an intervention in general  by using a sample size that is small and manageable (Kratochwill, 2015). In the above research question, the selected intervention is scaffolding which refers to the support provided to a child with reading and literacy problems and reduced as the child achieves the ability to independently execute the desired behavior. Scaffolding is rooted on the notion that regular interaction between a child and an adult or a teacher with emphasis on the achievement of desired behavior leads to improved performance in the behavior (Salem, 2017). 
From the proposed research question the independent variable is the grade of the children. In this proposal, the study will focus on grade 2 children because they are expected to achieve certain reading milestones by the time, they enter the grade level. Independent variable for this proposal can therefore be defined as follows: A child in grade 2 should have a high reading achievement that is equivalent to the reading milestones of learners in the same grade.  The dependent variable in this proposal is the reading achievement which can either be measured as high or low depending on the problem experienced by a learner thus calling for the need of an intervention which is scaffolding. Internal validity of the study will be improved by thoroughly  
identifying and selecting grade 2 learners with  genuine reading problems. Additionally, the sample size will be reduced to enhance accuracy in data collection and analysis.
