“Content validity tests or measures the behaviour or performance that it needs, to measure, what is taught, what students know and need further assistance in” (Maden, 2016). This lesson plan demonstrates a medium level of content validity as it uses blooms taxonomy’s level of thinking through investigating, conducting, planning, reflecting and communicating (Frangenheim, 2012, p.9), through conducting investigations, reflections and presentations. The majority of the content descriptions align with the Australian Curriculum for year 4. (Australian Curriculum, Assessment and Reporting Authority, 2016). However, the content description states that living things have life cycles, this is not included in the task sheet or rubric. As well as, students will suggest ways to plan and conduct investigations, yet the task sheet informs students to find a video to watch and source their information from. This is in contrast with the marking rubric which states that information is taken from more than one website to obtain an acceptable mark. Which demonstrates a discrepancy between the task and the rubric. As a result, students are not obtaining a higher level of thinking (Frangenheim, 2012, p.9), that they would otherwise obtain through wider investigation. Considering students have two lessons a week to work on assessment tasks, this is more than …show more content…
Flexibility allows all students a degree of choice to allow them to choose the format of assessment, so they can express their knowledge and ideas the best way they can (Maden, 2016). This is demonstrated within the lesson plan as students get to choose from a list of animals to research. However, as the classroom includes students from different cultures, this activity could be opened up further allowing students to choose any animal of interest allowing for cultural diversity within the classroom. This would allow for a student centred learning environment where activities are adjusted to the specific needs of the student’s, therefore, bringing their own experiences into the learning situation (Cavanagh &Prescott, 2015, pp 109-110). Whilst the rubric demonstrates flexibility in how the information was taken from more than one website, this is lacking in the task sheet as only one video is used and one online quiz to obtain information. Flexibility is low for the students with an intellectual impairment and considering the large diversity of students in the class, not all students will have to same knowledge, skill or confidence to use the computer for all of the research. Therefore, a wide range of resources should be introduced. Alteration in the marking rubric should also cater for students who are unable to write their
