Students' adaptive motivation to study tends to decrease over time. However, the reasons for this decline are not fully understood. Drawing on self-determination theory (SDT), we investigated whether changes in teachers' motivating style and students' associated need-based experiences could explain the motivational decline documented in the…

This study examined relations of affinity for solitude with social-behavioral, academic, and psychological adjustment in Chinese children and adolescents. The participants included 3,417 students (1,714 boys) in fourth, sixth, and eighth grades (M[subscript ages] = 10, 12, and 14 years, respectively) in China. Data on affinity for solitude were…

The study aimed to test the psychometric properties of a Portuguese adaptation of the "Adolescent Students' Basic Psychological Needs at School Scale" (ASBPNSS). For this, we used data from a sample of eighth graders (N = 1648; M[[subscript age] = 14.1 years; 46.9% girls) from Portugal. Cronbach alpha and omega coefficients showed the…

The purpose of this quantitative non-experimental cross-sectional study was to examine the possible relationship between students' autonomy, students' competence, and student-teacher relatedness, and their performance on ELA and math high-stakes tests. The self-determination theory was employed to guide the study. This study collected…

For some students, the transition from primary to secondary school is a difficult and stressful event that can have potential negative effects on their psychological wellbeing, social adaptability, and academic achievement. Although several individual, environmental, and family protective factors have been investigated, direct and indirect…

This study examines the direct and indirect relationships between key motivational constructs and science achievement using TIMSS 2019 data sets for Japan, Norway, and the United States. The sample of the study includes 4,446 and 8,698 eighth graders in Japan and the United States, with 4,575 ninth graders in Norway. The structural equation model…

We investigated the transmission of utility value from teachers to students by testing a model based on modern expectancy-value theory and empirical evidence for value transmission. A sample of 219 Korean 8th graders responded to surveys regarding the subject of history and their history teacher. Structural equation modelling showed that students'…

This study aimed to determine whether academic amotivation predicts academic achievement in middle-school students. In addition, it was examined whether the students' academic amotivation levels differed by their gender. Study sample consisted of 342 eighth-grade students from middle-schools in Kahramanmaras city in Turkey. Data were collected…

The present study examined the relationships of Taiwanese eighth graders' perceived autonomy support from teachers, parental psychological control, implicit theories of intelligence, and achievement goal orientations to their agentic, behavioral, emotional, and cognitive engagement in schoolwork. Also, the current research explored the determining…

The study examined the extent that teacher-student relationships (TSR) influenced basic psychological needs, engagement, and student growth using the self-systems process model as a framework using structural equation modeling. Based on prior research, it was hypothesized that context (TSR) influenced self (basic psychological needs), which…

School is where adolescents spend the largest share of their waking time. The present study focused on the factors that contribute to students' adjustment to school from a self-determination perspective. We tested the predictive value of parental behaviors (autonomy support, structure, and involvement) on the different dimensions of school…

In this systematic literature review, we examined the theoretical frameworks, construct operationalisation, and quantitative results as they relate to student motivation and science achievement in TIMSS studies. Our synthesis of findings derived from an international dataset present notable value in that the patterns identified regarding the…

This study uses Self-Determination Theory as a theoretical framework to test the hypotheses that students self-reports of their motivational regulations would predict teachers' perception of students' motivational regulations, even after controlling for performance. An additional aim was to test a process model in which students' perceived…

Much research has been done into the relationship between students' motivation to learn and their basic psychological needs as defined by the self-determination theory (autonomy, competence, relatedness). However, few studies have explored how these psychological needs relate to different types of maladaptive behavior in the classroom. To prevent…

Student motivation research seeks to uncover greater understanding of when, how, and why students succeed or fail in school settings. Self-determination theory has been at the forefront of helping educational stakeholders answer questions on student motivation. This study investigates the motivation mediation model proposed by self-determination…
