Students’ explanations of their mathematical thinking and conclusions have become a greater part of the assessment landscape in recent years. With a sample of 71 fourth-grade students at risk for mathematics learning disabilities, we investigated the relation between student accuracy in comparing the magnitude of fractions and the quality of students’ explanations of those comparisons, as well as the relation between those measures and scores on a criterion test: released fraction items from the National Assessment of Educational Progress. We also considered the extent to which reasoning and language contribute to the prediction. Results indicated a significant moderate correlation between accuracy and explanation quality. Commonality analyses indicated that explanation quality accounts for little variance in National Assessment of Educational Progress scores beyond what is accounted for by traditional measures of magnitude understanding. Implications for instruction and assessment are discussed.

General Quality

The aim of this paper is to examine secondary education learners’ performance in L2 writing production using the complexity, accuracy, and fluency constructs. Results show that the measures of fluency, accuracy, grammatical and lexical complexity progress in a significant way: fourth grade students outperform first graders in the aforementioned measures. Secondly, fewer correlations between the writing measures used and the general quality of the compositions are found among the older students than among the younger ones, indicating that the correlations change depending on learners’ age. Thirdly, 1st year students exhibit a higher ratio of errors, both in general and also by error category, although only two types decrease significantly in 4th year students: syntactic and spelling errors. Lastly, we find that errors tend to develop in a non-linear way.

This type of research is a Classroom Action Research with two cycles. Both cycles consist of three meetings. The subjects of the study were the fourth grade students. The initial condition showed that the score was 62,25 with the total number of students who passed were only 10 students and the number of students who hasn’t passed were 10 students. At the first cycle of mathematics learning the outcomes increased to become 75,50. It means the percentage of completeness reached 75%. At the second cycle the average of student’s learning outcomes increased again to become 83,00. Showed that percentage of completeness reached 90%, thus it can be concluded that the Discovery Learning based on 2013 curriculum model can improve student learning outcomes.
