Conjectures are a key component of mathematical inquiry, a process in which the students raise conjectures, refute or dismiss some of them, and formulate additional ones. Taking a design-based research approach, we formulated a design principle for personal feedback in supporting the iterative process of conjecturing. We empirically explored the…

The quality of life of students at school is an increasingly topical issue in relation both to public health issues, made more acute by the pandemic and successive confinements, and to the technical nature of future jobs which means training has become an economic issue. There are therefore two issues, one linked to health and the other to school…

The acquisition of research skills is an important goal of secondary education. Still, insights on what learner characteristics stimulate and hamper research skills are lacking. Therefore, this study investigates the relationship between students' research skills (assessed by means of the Leuven Research Skills Test (LRST) and students' gender,…

This longitudinal person-centered study aimed to identify profiles of subjective task values and ability self-concepts of adolescents in the domain of mathematics, English, biology, and physics in Grades 10 and 12. We were interested in gendered changes of profile membership, and in relations between profile membership and educational and…

Four topics were investigated in this longitudinal person-centered study: (a) profiles of subjective task values and ability self-concepts of adolescents in the domain of mathematics, (b) the stability of and changes to the profiles of motivational beliefs from Grade 7 to 12, (c) the relation of changes to student-perceived classroom…

One of the primary goals of teacher education is to aid preservice candidates in formulating a personal philosophy of teaching that is research-based. Teacher candidates should recognize that their philosophy of teaching and learning must be grounded in research-affirmed theory, certain dimensions of which (e.g., motivation) are critical to…

Increasing the number of students who study mathematics once it is no longer compulsory remains a priority for England. A longitudinal cohort from England (1085 students) was surveyed at Years 10 and 12. Students' self-beliefs of ability influenced their GCSE mathematics grades and their intended and actual mathematics subject-choices; the degree…

In this report, we describe the development of an extension of the "SuccessNavigator"® assessment for late high school settings. We discuss the assessment's conceptualization and support its application with psychometric studies detailing scale development in terms of structural analyses, reliability, and several other aspects of…

Do high school students who are predisposed to enroll in dual-credit courses already possess high levels of motivation or college and academic self-efficacy? Students in this study reported being academically motivated, but they did not report high levels of confidence in their ability to perform certain college-associated tasks. Of 52 items…

Research shows that carefully planned acceleration offers academic benefits with little social or emotional risk to high-ability learners. However, acceleration is underutilized and little is known about students' motivations to accelerate. In this study, 21 high-ability high school students in Grades 11 and 12 took part in a structured…

This study extends previous research on the long-term connections between motivation constructs in expectancy-value theory and achievement outcomes. Using growth mixture modelling, we examined trajectories of change for 421 students from 4th grade through college in their self-concept of ability (SCA) in math, interest in math, and perceived…

This mixed methods action study examines the relationship of students' three psychological needs of autonomy, relatedness and competence as presented in the Self-Determination Theory (Deci & Ryan, 1985) to the level of achievement of high school seniors at Litchfield High School. In the quantitative phase of the study, the quantitative…

The Advanced Virtual Academy (AVA) Twilight High School (THS) provides Houston Independent School District (HISD) high school students opportunities to earn credits toward graduation and pass state-mandated assessments. The program targets students who are at risk of not completing courses required to earn a high school diploma. This 2014-2015…

This paper discusses a K-12/university collaboration in which students participated in a four-day scenario-based summer STEM (science, technology, engineering, and mathematics) camp aimed at making difficult scientific concepts salient. This scenario, Jumpstart STEM-CSI: Chocolate Science Investigation (JSCSI), used open- and guided-inquiry…

The Advanced Virtual Academy Twilight High School (Twilight High School) provides Houston Independent School District (HISD) high school students with opportunities to earn credits toward graduation and targets students who are at risk of not completing courses required to earn a high school diploma.
