Elementary school children’s understanding of science: The implementation of an extracurricular science intervention

The promotion of students’ achievement and competence in the so-called STEM disciplines is one cornerstone of current educational research and practice. In particular, as early as elementary school, the fostering of an adequate understanding of science is a normative goal of science education. It facilitates students’ science learning and enables them to understand the nature and development of scientific knowledge. Based on the relevance of the promotion of young children’s understanding of science, a corresponding science intervention was recently developed and successfully evaluated in a first study under highly controlled conditions. The goal of the present study was to investigate the effectiveness of this intervention when implemented in practice. One hundred seventeen third- and fourth-grade students and 10 trained course instructors participated in this study. We applied a randomized block design with waitlist control groups and repeated measures. The results revealed that children assigned to the intervention compared with children assigned to the waitlist control group showed better inquiry-related methodological competencies (a better understanding of the scientific inquiry cycle and experimentation strategies) and a higher need for cognition. The findings point to the successful implementation of the intervention and are compared with the results of the first study.     

The influence of extracurricular activities on middle school students’ science learning in China

ABSTRACT

Informal science learning has been found to have effects on students’ science learning. Through the use of secondary data from a national assessment of 7410 middle school students in China, this study explores the relationship among five types of extracurricular science activities, learning interests, academic self-concept, and science achievement. Structural equation modelling was used to investigate the influence of students’ self-chosen and school-organised extracurricular activities on science achievement through mediating interests and the academic self-concept. Chi-square tests were used to determine whether there was an opportunity gap in the student’s engagement in extracurricular activities. The students’ volunteer and school-organised participation in extracurricular science activities had a positive and indirect influence on their science achievement through the mediating variables of their learning interests and academic self-concept. However, there were opportunity gaps between different groups of students in terms of school location, family background, and especially the mother’s education level. Students from urban areas with better-educated mothers or higher socioeconomic status are more likely to access diverse science-related extracurricular activities.     

The dimensions and impact of informal science learning experiences on middle schoolers’ attitudes and abilities in science

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.     

The nature of students’ informal science conceptions

Case studies have been constructed of primary school children's developing explanations of a range of air pressure phenomena. A range of conceptions relating to air pressure have been identified, and insights gained concerning the way these interrelate over time and over context. It was found that children are naturally generative in their construction of explanations, but that they use conceptions in quite complex and fluid ways. It is argued that naive conceptions maintain a valuable function as intuitive recognition elements that feed more sophisticated conceptions, and that generating a satisfying explanation for a phenomenon can involve having access to a range of interrelated conceptions. A range of contextual factors were identified, which influence the construction of explanations, and can act as barriers to the application of scientific conceptions.     

The effect of schools on school leavers’ university participation

ABSTRACT

This paper considers the role that schools have in determining whether school leavers participate in higher education or not. It examines the association between schools and university participation using a unique dataset of 3 cohorts of all young people leaving maintained schools in Wales. School “effects” are identified, even after controlling for individual-level factors, such as their prior attainment, socioeconomic circumstances, ethnicity, and special educational needs. Schools appear to have a particular “effect” on the likelihood that a young person enters an elite university. However, the findings suggest the concept of a school “effect” on higher education participation is not straightforward – schools appear to have different levels of effectiveness depending on the gender of the young people and the nature of their higher education participation. These findings are considered within the policy contexts of school effectiveness and widening access to higher education.     

Exploring an intervention’s impact on everyday school activities

The focus of this paper is on a group of pupils with reading and writing difficulties who have been participating in an intervention study using assistive technology. That intervention study contained supervised training sessions with reading and writing tasks using an iPad with special supportive applications. The current study is a qualitative investigation of whether there has been any transfer from the intervention, to the pupils’ everyday school activities. Interviews with pupils and their teachers and observations during classroom lectures have been used to collect data. The results show that the pupils were positive to the assistive technology (the applications on the iPads), they found the apps easy to learn how to use and they appreciated the benefits they could give. Even so, only a few of the pupils had found use for and continued to use the tools after the intervention period finished. Possible reasons are that when the novelty wore off, students reverted to their usual study habits and that older students with many teachers and different classrooms were less able to adapt to using the apps. To improve transfer, it is suggested to introduce assistive technology earlier to students, in the younger grades, before study habits have been formed and to inform teachers about the use of AT in the classroom, including what is available and how it can benefit students.     

Investigating the effect of an adaptive learning intervention on students’ learning

Educators agree on the benefits of adaptive learning, but evidence-based research remains limited as the field of adaptive learning is still evolving within higher education. In this study, we investigated the impact of an adaptive learning intervention to provide remedial instruction in biology, chemistry, math, and information literacy to first-year students (n = 128) entering a pharmacy professional degree program. Using a mixed methods design, we examined students’ learning in each of the four content areas, their experience using the adaptive system, and student characteristics as related to their choice of participating in the intervention. The findings showed the adaptive learning intervention helped address the knowledge gap for chemistry, but the same effect was not observed for the other three content areas. Math anxiety was the only student characteristic that showed a significant relationship with students’ participation. While the students reported an overall positive experience, the results also revealed time factor and several design flaws that could have contributed to the lack of more student success. The findings highlight the importance of design in adaptive learning.     

The nature and development of middle school mathematics teachers’ knowledge

In this article, we report on the use of a teacher profiling instrument with 62 middle school teachers at the start of a 3-year professional learning programme. The instrument was designed to assess the aspects of teachers’ knowledge identified by Shulman (1987) refined by Ball et al. (2008) and extended to include teachers’ confidence to use and teach various topics in the middle school mathematics curriculum and their beliefs about mathematics teaching and learning. Based on a hierarchical coding of items, the application of the partial credit Rasch model revealed that the profile items were measuring a single underlying construct and suggested that the various facets of teacher knowledge develop together. We describe the characteristics of four levels of the hierarchical construct measuring teacher knowledge and understanding for teaching mathematics in the middle years of schooling, and discuss the unique affordances of a holistic view of teacher knowledge in contrast to considerations of multiple knowledge categories.     

Students’ perceptions of vocabulary knowledge and learning in a middle school science classroom

This study investigated eighth-grade science students’ (13–14-year-olds) perceptions of their vocabulary knowledge, learning, and content achievement. Data sources included pre- and posttest of students’ perceptions of vocabulary knowledge, students’ perceptions of vocabulary and reading strategies surveys, and a content achievement test. Students’ perceptions of vocabulary knowledge were compared before and after instruction to see whether students believed they gained knowledge and the ability to explain categories of technical science terms. Students’ perceptions of vocabulary knowledge increased as a result of instruction. The participants had favorable views of the vocabulary and reading strategies implemented and believed the literacy approaches were important for their developing science knowledge. In addition, students’ content achievement was compared to a national data set. Students in this study outperformed a national data set on all content knowledge items assessed. Students’ perceptions of their knowledge and vocabulary and reading strategies were congruent with their content achievement. This study is one of the first to highlight the pivotal role students’ perception of vocabulary knowledge and vocabulary and reading strategies plays in science content learning.     

The effect of a middle grades STEM initiative on students’ cognitive and non-cognitive outcomes

This study is an evaluation of a STEM initiative in one school district with five participating middle schools. I used two quasi-experimental methods including instrumental variables and inverse propensity score weights to test the effect of the initiative on students’ cognitive and non-cognitive outcomes. Overall, students at STEM schools demonstrated lower science achievement (p < .05). Subgroup analyses showed that Limited English Proficient students at STEM schools demonstrated increased reading achievement and fewer unexcused absences (p < .001). Black students demonstrated increased grit (p < .01), and Hispanic students demonstrated increased control and relevance in learning (p < .001).     

The effects of emotional design on middle school students’ multimedia learning: the role of learners’ prior knowledge

Abstract

Extending studies on emotional design in multimedia learning beyond college samples and further considering individual differences, we examined the effects of emotional design on middle school students’ learning and whether this relationship is moderated by learners’ prior knowledge, using a computer-based lesson covering the topic “the formation of lightning.” Participants were middle school students (N?=?124; 58 females; age range 13 to 16) who volunteered to participate with permission. Learners with high prior knowledge (n?=?63) and learners with low prior knowledge (n?=?61) were randomly assigned to one of two instructional design conditions: positive emotional design (colourful and anthropomorphic features) and neutral emotional design (grey and non-anthropomorphic features). The results showed that the positive emotional design operationalised via visual elements did not induce more positive emotions than the neutral design group, although there was a trend towards facilitating more learning transfer (η²_p?=?.02, p?=?.098) and increasing the mental effort of learners with low prior knowledge (η²_p = .03, p?=?.06). There was a tendency for learners with high knowledge to perceive higher mental effort (η²_p?=?.03, p?=?.06), satisfaction (η²_p = .05, p?=?.01) and achieve better transfer scores (η²_p = .03, p?=?.087) compared with those learners with low knowledge. These findings suggest that positive emotional design should be cautiously applied in multimedia learning for middle school students. Individual differences must be considered in instructional design in a multimedia learning environment.     

Pre-service teachers’ perceptions of middle school students

This report shares a study that explored the perceptions pre-service teachers have of middle school students. Participants were asked to complete the Adjective Checklist (ACL) by endorsing the words they considered most characteristic of a typical middle school student. Items most frequently endorsed indicated a predominantly negative perception (e.g. “awkward”, “confused” and “emotional”). Implications for pre-service teacher training are discussed.     

A school-based intervention on elementary students’ school engagement

Prior research has reported signs of low engagement in the early stages of schooling. The present study assessed the effectiveness of a school-based intervention that promotes cognitive, emotional, and behavioral engagement in elementary school children through a story tool. The study followed a cluster-randomized design with 259 fourth graders nested in 12 classes; the classes, not the individuals, were randomly assigned to an intervention or control group. Both groups were assessed in four waves in two measures for each engagement dimension. Data were analyzed with a multilevel approach. Findings show that the intervention enhanced students’ cognitive, emotional, and behavioral engagement. Still, there is a delay before the intervention program exhibits a beneficial effect.Moreover, gender discrepancies were found. Before the intervention, girls showed higher cognitive and emotional engagement, but boys exhibited higher emotional engagement after the intervention. In addition, current results indicate that the program benefited the boys more than the girls. Finally, there was no evidence that the engagement outcomes differed depending on the parent’s educational level. Findings provide valuable information for future research and educational practice.     

Revisiting “The fertilization fairytale:” an analysis of gendered language used to describe fertilization in science textbooks from middle school to medical school

Emily Martin’s (Signs J Women Cult Soc 16(31):485–501, 1991) article, “The Egg and the Sperm: How Science Has Constructed a Romance Based on Stereotypical Male–Female Roles,” was published in Signs over 20 years ago. In this groundbreaking article, she discusses how gender roles are often projected onto reproductive biology, leading to the portrayal of eggs as passive and sperm as active. We were interested in seeing if many of her findings are still relevant today. We analyzed science textbooks from the middle school to the medical school level to determine if fertilization in human reproduction is described in gender-biased language regarding the sentence structure, amount of information provided for female and male processes/parts, and neutrality in describing female and male processes/parts. Although there has been much improvement, there is still a long way to go. Sexist language in scientific textbooks is troubling because it negatively affects both female and male students and undermines teachers’ ability to teach in an accurate and gender-neutral way.     

Influences on US middle school teachers’ use of environment‐based education

The term environment‐based education (EBE) describes a form of school‐based environmental education in which an instructor uses the environment as a context for integrating subjects and a source of real world learning experiences. Despite the growing body of evidence that supports the educational efficacy of this instructional approach and its grounding in high‐quality environmental education, relatively few US teachers seem to practice EBE (University of Maryland Survey Research Center 2000 University of Maryland Survey Research Center. 2000. Environmental studies in the K‐12 classroom: A teacher’s view, College Park, MD: Author.  [Google Scholar]). In the context of encouraging more widespread adoption of this formal instructional approach, the author used survey research with a random sample of fifth–eighth grade teachers in US public schools to investigate influences on their decisions to use EBE and barriers to EBE implementation. The study also investigated how perceived influences on and barriers to EBE teachers differed from perceptions of teachers using other forms of environmental education and teachers using neither approach. Results suggest the importance of the following in teachers’ decisions to use EBE: positive environmental attitudes; environmental sensitivity; receptiveness to EBE; teaching context; and environmental literacy knowledge and skills. The influence that best discriminated between EBE teachers and teachers using other forms of environmental education was evidence of positive outcomes. The barrier that best discriminated among EBE teachers, teachers using other forms of environmental education, and teachers not using any form of environmental education was lack of training.     

Teachers’ conceptions of representation in middle school mathematics

Current reform efforts call for an emphasis on the use of representation in the mathematics classroom across levels and topics. The aim of the study was to examine teachers’ conceptions of representation as a process in doing mathematics, and their perspectives on the role of representations in the teaching and learning of mathematics at the middle-school level. Interviews with middle school mathematics teachers suggest that teachers use representations in varied ways in their own mathematical work and have developed working definitions of the term primarily as a product in problem solving. However, teachers’ conception of representation as a process and a mathematical practice appears to be less developed, and, as a result, representations may have a peripheral role in their instruction as well. Further, the data suggested that representation is viewed as a topic of study rather than as a general process, and as a goal for the learning of only a minority of the students—the high-performing ones. Implications for mathematics teacher education, prospective and practicing, are discussed.     

The effect of an historical perspective on prospective teachers’ beliefs in learning mathematics

Many learners hold traditional beliefs about mathematics that can hamper their learning in the discipline. To address this issue, a “history-based” intervention program entailing problem-solving and writing activities that instigate cognitive conflict was implemented. Data sources were pretest and posttest scores of a 12-theme questionnaire designed for this study called “Prospective teachers’ beliefs questionnaire about mathematics learning” and written reflections of prospective teachers. The survey of the prospective teachers beliefs related to the nature of mathematics and the way it is learned, taught, and practiced showed a great majority of them failed to hold progressive beliefs. Fortunately, the intervention program has helped the prospective teachers revise and correct their beliefs, thoughts, and understandings. Study of the prospective teachers’ written reflections and observations of their oral presentations during whole-class discussions strengthen the results of the quantitative study.     

A comparative study of effect of new and old science curriculum on Chinese junior high school students’ abstract thinking

“Teenagers’ abstract thinking ability test” was designed in accordance with the structure and performance of teenagers’ ability to think abstractly. 138 Chinese junior high school students who learned New curriculum and old curriculum separately were measured. A comparison between the two kinds of students shows that abstract thinking ability of the former is notably higher than that of the latter. However, the performance of differences varies by school and gender.
