Probability is a difficult concept, which is not always taught accurately. This study aims to clarify how experimental and theoretical probabilities are taught in Japanese 7th and 8th grades through a textbook analysis. We analyzed seven, government approved Japanese 7th and 8th grade textbooks each. Focusing on the definition and explanation of…

In Norway 5.8% of students report being bullied as much as three or more times a month [UDIR. 2021a. Student Survey 2020 [Elevundersøkelsen 2020]. https://www.udir.no/tall-og-forskning/finn-forskning/rapporter/elevundersokelsen-2020-nasjonale-tall-formobbing-og-arbeidsro/]. The present study investigates the likelihood of students being bullied…

We estimate the relationship between exclusionary discipline given in eighth-grade and the probability of ninth-grade retention. We use a rich 7-year, student-level, panel data set from Arkansas. We use a novel approach by limiting our sample to students who switch schools between eighth and ninth grades. This movement gives each student a fresh…

This paper investigates two specific probabilistic biases which middle graders usually exhibit when reasoning about probability and randomness on assessment items. We discuss how students' reasoning about key probability concepts undergirds statistics literacy related to randomness, independence, and the likelihood of future events based on past…

This study examines the development of learning designs based on Realistic Mathematics Education (RME) on the probability topic at the eighth-grade junior high school level. Probability abounds in everyday life, and the RME approach is believed to develop students' mathematical communication skills. This learning design development used the Plomp…

This research is aimed to describe a learning trajectory for probability through game-based learning. The research employed design research consisting of three stages: preparing for the experiment, design experiment, and retrospective analysis. A hypothetical learning trajectory (HLT) using Sudoku and Snake-and-ladder games was developed by…

The academic effects of learning statistics and probability through peer tutoring were analysed in the research reported on here. Two hundred and eight students enrolled in Grades 7, 8 and 9 participated. Fixed- and same-age peer tutoring was implemented 3 times per week for 6 weeks. Each tutoring session lasted approximately 25 minutes. The main…

This paper examines the likelihood of violence in successive cohorts of students in a small city during the implementation of a youth-led sexual violence prevention initiative. We compared the likelihood of violence among students who were in 8th, 9th, and 10th grade before the programming to the likelihood of violence among students who were in…

Few studies have been conducted to investigate typologies of perpetration and victimization of traditional and cyber bullying together to develop a risk profile by considering factors from different contexts. National data from the 2009-2010 Health Behavior in School-Aged Children study in the United States was utilized for these purposes. Four…

High school calculus has become indispensable for students seeking a college degree in a STEM field. However, in the present study, we argue that the mathematics opportunities that students seize (when afforded) in middle grades are the key to earning calculus credit in high school. To take calculus in high school, students usually need to take…

This study examined participation in accelerated college credit programs dual enrollment, concurrent enrollment, and Advanced Placement courses in Rhode Island high schools to understand their effects on educational attainment in the 2013/14 grade 9 cohort. The state, which has funded and promoted these opportunities for students to earn college…

This Study Snapshot highlights key findings where the Rhode Island Department of Education, the Rhode Island Office of the Postsecondary Commissioner, and state legislators sought evidence of the effects of state-funded programs for students to earn college credit during high school. Using data on the 2013/14 statewide grade 9 cohort, this…

The "The Effects of Accelerated College Credit Programs on Educational Attainment in Rhode Island" study examined participation in accelerated college credit programs dual enrollment, concurrent enrollment, and Advanced Placement courses in Rhode Island high schools to understand their effects on educational attainment in the 2013/14…
