Utility value is associated with positive learning outcomes in science and is often used to motivate engagement in the sciences, but less is known about what influences its development and maintenance, particularly during the critical middle school years. Using multinomial regression applied to longitudinal data from approximately 2600 middle-school students, we test the relationship of science classroom experiences (affective engagement, behavioral-cognitive engagement, & perceived success) and optional formal and optional informal experiences to changes in science utility value. Furthermore, we address whether the same factors that predict growth in utility value also predict absence of decline. Overall, we find all five factors are associated with changes in utility value, but some have different relationships with growth vs. decline outcomes. These findings provide a more nuanced view of factors associated with utility value towards science (both in and out of the science classroom), as well as practical implications for educational practice.

While motivational changes towards science are common during adolescence, our work asks which perceived classroom experiences are most strongly related to these changes. Additionally, we examine which experiences are most strongly associated with learning classroom content. In particular, using self-reports from a sample of approximately 3000 middle school students, this study investigates the influence of perceived science classroom experiences, namely student engagement and perceived success, on motivational change (fascination, values, competency belief) and content knowledge. Controlling for demographic information, school effects, and initial levels of motivation and content knowledge, we find that dimensions of engagement (affect, behavioural/cognitive) and perceived success are differentially associated with changes in particular motivational constructs and learning. Affective engagement is positively associated with motivational outcomes and negatively associated with learning outcomes, behavioural-cognitive engagement is associated only with learning, and perceived success is related only to motivational outcomes. Theoretical and practical implications are discussed.
Multiple reasons shape how young people and families choose to participate in informal learning programs at museums and other settings. Youth interest is likely a factor, but so might be geographic proximity, institutional affiliation, household income, and race/ethnicity. We examined the relative impact of these factors through a comparative study of two art programs; one a small, neighborhood-based organization focused on art and STEM, and the other a program in a well-established art museum. The smaller program tended to draw youth from closer geographic proximity. Interest in art drove attendance at both programs, but institutional membership was also important. Demographic factors also were a factor, and race/ethnicity was more strongly associated with program placement than household income. We discuss the importance of better understanding of such factors as museums and other programs continue to grow as important sites for learning.
Learners encounter science in a wide variety of contexts beyond the science classroom which collectively could be quite influential on student attitudes and abilities. But relatively little is known about the relative influence of different forms of informal science experiences, especially for the kinds of experiences that students typically access. We conduct factor and regression analyses on data collected from a large number of diverse public-school attending 6th and 8th graders drawn from two regions in the USA. Students completed a science reasoning measure and surveys of attitudes, previously completed informal science learning experiences, and demographic factors. Factor analyses identify four dimensions of informal science learning participation (in home, semiformal, nature, and museums). Regression analyses find a relative specificity of effects, with particular outcomes associated with a subset of the forms of informal science participation, highlighting the importance of controlling for correlated factors. There were also a few differences by grade level, with different experiences influencing the development of competency beliefs in science in early vs. late middle schoolers.
Overall interest in science has been argued to drive learner participation and engagement. However, there are other important aspects of interest such as breadth of interest within a science domain (e.g., biology, earth science). We demonstrate that intensity of science interest is separable from topic breadth using surveys from a sample of 600 middle school students. We also show that these two dimensions contribute differently to learning-relevant behavioral tendencies. Specially, regression analyses show: (1) that intensity of interest predicts both self-reported science classroom engagement and preferences to participate in optional science learning; and (2) that breadth of interest predicts science choice preference, but not science classroom engagement. These findings have implications for the conceptualization of interest, the measurement of interest, and practical applications for educators.
Scientific literacy has many meanings: it can be thought of as foundational knowledge, foundational critical thinking skills, or the application of these two foundations to everyday decision making. Here, we examine the far transfer scenario: do increases in science education lead to everyday decision-making becoming more consistent with consensus scientific knowledge? We report on a large sample of employees of a mixed urban/rural county representing a diverse range of careers, who completed an anonymous survey about their environmental conservation actions at home, as well as their general education level and their science coursework. Across broad and narrow measures of science education, we find little impact on action. Possible causes of this failure of transfer and the implications for changes in science instruction are discussed.
How is a child's successful participation in science learning shaped by their family's support? We focus on the critical time period of early adolescents, testing (i) whether the child's perception of family support is important for both choice preferences to participate in optional learning experiences and engagement during science learning, and (ii) whether the effects on choice preferences and engagement are mediated through effects on child interest and self-efficacy in science. Structural equation modeling is applied to data from two different contexts, one examining engagement during a science and technology center visit and the other examining engagement and learning during classroom instruction. Models from both datasets suggest that early adolescents' perceived family support for learning is associated with their choices for and engagement in science learning, and that these effects are mediated by effects on child interest and self-efficacy in science. Further, children's family physical resources (e.g., available learning spaces and materials) predicts their perceived family support, but is not separately connected to either interest or self-efficacy.

Cumulatively, participation in optional science learning experiences in school, after school, at home, and in the community may have a large impact on student interest in and knowledge of science. Therefore, interventions can have large long-term effects if they change student choice preferences for such optional science learning experiences. To be able to track K-12 students' intentions to participate in optional science learning experiences, we developed a new measure of science choice preferences in early adolescence. The present study with 284 5th and 894 6th graders from diverse school contexts (i.e., from the Bay Area and the Pittsburgh area) illustrates the value of applying Item Response Theory analyses to develop a measurement instrument. These analyses established the overall reliability of the instrument and each item in the scale, as well as the generalizability of the scale and individual items across subgroups by gender, by ethnicity, and by achievement levels in science. Further, preferences to participate in science were shown to be separate from preferences to participate in mathematics, engineering, or medicine. Finally, the science choice preferences measure is validated through replicated positive correlations with levels of science interest, self-efficacy, and learning achievement.
