Abstract:
The purpose of this research were to study the mathematical ability of Mathayomsuksa 3 students NongkungsriWitthayakhan School Nong Kung Si District Kalasin Classified by Bloom's Taxonomy. The target group used in research were students in a Mathayomsuksa 3 at Nongkungsri Witthayakhan School in the second semester of 2018 with 65 students. The research instruments were Math ability test and math ability test in accordance with Bloom's Taxonomy. The statistics used in the study were percentage and arithmetic mean. By using the test scores for mathematical ability of the IPST. And T-score is used to determine the level for Mathematical ability of Bloom's Taxonomy's of SomnuekPhatthathani.
The results showed that Students with high computational ability had a moderate level of Knowledge (80%), a moderate level of Comprehension (90%), a moderate level of Application (76.19%), a high level of Analysis (55%), a low level of Synthesis (40%) and a high level of Evaluation (55%). Students with high problem solving ability had a moderate level of Knowledge (77.27%), a moderate level of Comprehension (85.71%), a moderate level of Application (72%), a low level of Analysis (81.82%), a low level of Synthesis (68.18%) and a low level of Evaluation (72.73 %). And students with high reasoning ability had a moderate level of Knowledge (80%), a moderate level of Comprehension (80 %), a moderate level of Application (60 %), a low level of Analysis (100 %), a moderate level of Synthesis (80 %) and a high level of Evaluation (80%).
