Math problem solving frequently involves choices among alternative strategies. Strategy choices, and effects of problem features on strategy choices, both vary among individuals. We propose that individual differences in strategy choices can be well characterized in terms of parametric variation in three types of influence: global bias, relevant…

The purpose of this study was to reveal middle school students' digital literacy levels and their opinions about digital literacy. Convergent parallel design, one of the mixed-method designs, was used in the study. Quantitative part involved survey while qualitative part included casestudy model. Digital literacy scale and semi-structured…

Motivated by a curriculum privileging number-based strategies but national tests highlighting students' reliance on standard algorithms, this study analyses 2,216 Danish Grade 3, 6 and 8 students' solutions to various multidigit arithmetic tasks, each designed to elicit shortcut strategies, against background variables including sex, ethnicity and…

Previous research provides evidence that developing a growth mindset--believing that one's capabilities can improve--promotes academic achievement. Although this phenomenon has undergone prior study in a representative sample of ninth graders in the United States, it has not been studied in representative samples of other grade levels or with…

The current study assessed whether adding worked examples with self-explanation prompts focused on making connections between mathematical principles, procedures, and concepts of rational numbers to a curriculum focused on invented strategies improves pre-algebra students' fraction number line acuity, rational number concepts and procedures.…

We examined the development of numerical magnitude representations of fractions and decimals from fourth to 12th grade. In Experiment 1, we assessed the rational number magnitude knowledge of 200 Chinese fourth, fifth, sixth, eighth, and 12th graders (92 girls and 108 boys) by presenting fraction and decimal magnitude comparison tasks as well as…

There is a lack of research on students' conceptions of giftedness and intelligence, despite recognition of their influence on real-life factors such as achievement and motivation. This paper presents a cross-sectional mixed methods study that investigated Finnish students' (age 6-16 years; N = 1282) implicit conceptions of giftedness and…

The article presents findings from a Czech environmental literacy survey conducted in 2020 on a sample of 6th (N = 3773), 8th (N = 21518), and 9th graders (N = 4368). Specifically, the effect of environmental and sustainability education (ESE) as well as the effect of gender and age on environmental knowledge, attitudes, beliefs, place attachment,…

We explored how gender and gender similarity affects friendship dissolution following the transition to middle school. We predicted that both gender and gender similarity (measured by perceived similarity to own-gender and other-gender peers) explain dissolution trends and that less own-gender similarity or more other-gender similarity predicts…

Second Language Pragmatics (L2 pragmatics) research focused on the study abroad (SA) context points out the benefits of this context for second language (L2) pragmatic development while also illustrating the non-linearity of this development, as it is shaped by different contextual factors and individual differences. Nevertheless, this research…

The main purpose of the current study is to investigate middle school students' math self-efficacy perceptions and math problem posing attitudes. The sample of the study is comprised of 990 fifth, sixth, seventh and eighth grade students attending middle school in the Fethiye district of the city of Mugla. As the data collection tool, the…

This study classifies the verbal feedback of science teachers into praise statements, effort-based feedback statements, negative feedback statements, and ability-based statements, which are also regarded as feedback strategies. The study aims to investigate the feedback strategies used by science teachers in the classroom setting using descriptive…

Algebra I is a crucial course for middle and high school students for successful STEM related coursework. A key issue is whether students should take Algebra I in 8th versus 9th grade. Large-scale policy studies show conflicting results, and there are few (particularly longitudinal) individual difference studies. Here, 53 students were assessed in…

While the importance of social-emotional learning for student success is well established, educators and researchers have less knowledge and agreement about which social-emotional skills are most important for students and how these skills distribute across student subgroups. Using a rich longitudinal dataset of 221,840 fourth through seventh…

One obstacle to understanding abstract concepts such as the "control of variables" strategy (CVS) is the tendency for learners to focus on surface rather than deep features in instructional materials. However, in tasks such as learning CVS, these same surface features may also support understanding, provided learners realize the…
