This research focuses on the retention of students' algebraic understandings 1 year following a 3-year early algebra intervention. Participants included 1,455 Grade 6 students who had taken part in a cluster randomized trial in Grades 3-5. The results show that, as was the case at the end of Grades 3, 4, and 5, treatment students significantly…

Based on a cognitive diagnostic model, an online individualised tutor program was developed in this study. An experiment was conducted in practical educational settings exploring the effectiveness of the online individualised tutor remedial program based on the diagnostic reports of the cognitive diagnostic model. The methodology of this study was…

Being able to use the words that are learned and encountered in school is an important skill for communicating and displaying understanding. Students are increasingly expected to be able to appropriately and effectively use complex academic words in their writing, yet we know little about this productive aspect of word knowledge. This study…

Since 1973, the National Assessment of Educational Progress (NAEP) has gathered information about student achievement in mathematics. Results of these periodic assessments, produced in print and web-based formats, provide valuable information to a wide variety of audiences. They inform citizens about the nature of students' comprehension of the…

This study examined the psychometric properties and measurement invariance of the Arabic version of "My Class Activities" (MCA), an instrument designed to measure students' perceptions of interest, challenge, choice, and enjoyment in classrooms. Scores of 3,516 Sudanese students in Grades 2 to 8 were used. Confirmatory factor analysis…

This supplement describes national adaptations made to the international version of the TIMSS 2011 background questionnaires. This information provides users with a guide to evaluate the availability of internationally comparable data for use in secondary analyses involving the TIMSS 2011 background variables. Background questionnaire adaptations…

Multiple-choice (MC) reading comprehension test items comprise three components: text passage, questions about the text, and MC answers. The construct validity of this format has been repeatedly criticized. In three between-subjects experiments, fourth graders (N[subscript 1] = 230, N[subscript 2] = 340, N[subscript 3] = 194) worked on three…

Two curriculum-based measurement tools are commonly used to assess progress in reading in elementary school: R-CBM and CBM maze. R-CBM is used in practice more frequently than CBM maze is, although CBM maze is more time efficient to administer than R-CBM is. The technical adequacy of each of these measures has been reported in the literature;…

This study sheds light on the achievement gap between two culturally diverse populations in Israel by employing a diagnostic model for analysing responses of a representative sample of Jewish and Arab fourth graders on a national mathematics test. The results indicated large significant differences, in favour of the Jewish group, on most…

For more than 50 years, the International Association for the Evaluation of Educational Achievement (IEA) has been conducting comparative studies of educational achievement in a number of curriculum areas, including mathematics and science. TIMSS 2011 represents the fifth cycle of the Trends in International Mathematics and Science Study (TIMSS),…

The purpose of this study was two-fold: (a) to explore the nature of elementary school children's metacognitive knowledge of strategies appropriate for before, during, and after reading; and (b) to determine whether children who had participated in Reading Recovery instruction in the first grade had similar understandings as their current third-…
