Abstract:
The purpose of the experiment was to examine whether students better understand a science text when they are asked to self-generate summaries or to study predefined summaries. Furthermore, we tested the effects of verbal and pictorial summaries. The experiment followed a 2 x 2 design with representation mode (verbal vs. pictorial) and learning activity (self-generating vs. studying) as experimental factors. The main dependent variables were learning performance, measured by a comprehension and a transfer test, and strategy use, measured by self-report scales. Seventy-one students (Grade 10) participated in the study. The results showed that studying predefined summaries in a pictorial representation mode facilitated deep understanding. Furthermore, mediation analysis showed that the effect of representational mode was mediated by students' spatial representations of learning content. The effect of spatial representations was in turn facilitated by mental imagery activities. (Contains 3 figures and 3 tables.)

Abstract:
This study explores the influence of religion as a support factor for a group of Latina and African-American women majoring in science. The current project is a part of a larger study that investigated persistence factors of underrepresented woman who were enrolled as science majors at United States colleges and universities. This paper focuses on one theme that emerged among six participants who disclosed how religion was a significant influence on their persistence in science fields. The strength and support offered by religious values is certainly not specific to science content; however, the support received from their beliefs highlights a potential area for further exploration. Given the importance of increasing participation by students from diverse backgrounds into science fields, it is critical to recognize how some of these differences may be the key factors influencing the way these students look at the world. This study offers evidence that science educators need to consider what role religious beliefs have for students who may be considering science or science education as a future career, particularly for those students from underrepresented groups.

Abstract:
This study validated the Chinese version of the Questionnaire on Teacher Interaction (QTI) in the Hong Kong context as well as examined the relationship between students' perceptions of interpersonal teacher behaviour and their cognitive, affective and moral learning outcomes. Data were collected with the QTI and four other measures of student learning outcomes including a modified enjoyment scale of the Test of Science Related Attitudes, academic achievement, attitudes towards the teacher, and learning of values and attitudes. A total of 612 grade 9 students from 16 Mathematics, Chinese and English classes in six schools participated in the study. The Chinese version of the QTI was found to be a valid and reliable measure. Multiple regression analysis revealed that students' perceptions of their teachers' interpersonal behaviour were significantly related to their cognitive, affective, and moral learning outcomes.

Abstract:
Betty's Brain is an open-ended learning environment in which students learn about science topics by teaching a virtual agent named Betty through the construction of a visual causal map that represents the relevant science phenomena. The task is complex, and success requires the use of metacognitive strategies that support knowledge acquisition, causal map construction, and progress monitoring. Previous research has established that middle school students struggle at such tasks without proper scaffolding and feedback. In Betty's Brain, this feedback is provided by Betty and Mr. Davis, another virtual agent designed to provide guidance and suggestions as students work. This paper discusses our implementation of contextualized conversational (CC) feedback, and then presents the results of an experimental study exploring the effects of this feedback in two 8th-grade science classrooms. The results illustrate some advantages of the CC feedback in comparison with a baseline dialogue mechanism that presents similar strategies in a non-conversational, non-contextualized form. While both groups showed significant pre-to-post test learning gains, the difference in learning gains between the groups was not statistically significant. However, students who received CC feedback more often performed actions in accordance with the advised strategies, and they created higher quality causal maps.

Abstract:
The value of mangroves and mangrove ecosystems has not always been recognized. In fact, mangroves were historically regarded largely as wastelands with little or no value. Over time, humans began to recognize the multiple ways in which they could be used, particularly through development, making the mangrove ecosystem vulnerable to destruction and depletion, a globally alarming issue. Mangrove depletion is presented here as socioscientific issue cases with activities designed to promote and strengthen ocean literacy. Through these activities, students can explore scientific concepts relating to mangrove ecosystems while fostering moral and ethical reasoning to determine what is affected and valued, and who shares responsibility.

Abstract:
In the following article, Dr. Seuss's children's books are creatively integrated with science activities through the creation of take-home activity kits. The kits provide families an opportunity to read at home while connecting the enjoyable experience to science content and skill development through associated activities. The kits should be constructed using easy-reading books and aligned to developmentally appropriate academic science standards. Most importantly, they should be designed in a manner so that all family members are participants rather than expecting the adults to teach the expected outcomes. The activity kits can be completed as stand-alone experiences for interested students, used by students who are ready for an additional challenge, or adapted for an entire classroom of students as part of a teacher's normal curriculum.

Abstract:
Although literacy plays a large role in elementary science classrooms, one thing that offers a challenge for educators is meeting the linguistic needs of English language learners (ELLs) while also meeting their content needs. An additional challenge is ensuring that academic literacy extends beyond the classroom. This article presents ways of extending classroom literacy into the home. The suggestions and activities emphasize literacy strategies appropriate for ELLs as well as English-speaking students. (Contains 4 figures and 9 resources.)

Abstract:
Established in the early 1970s, the talent search model has garnered strong theoretical and programming support for addressing the academic needs of highly able students. The two main components of the talent search model are discovery (identification) and development (programming) of academic talent. Discovery of academically talented elementary and middle school students occurs via the process of above-level testing, usually offered through university-based centers. The essence of talent search program intervention is acceleration, which has robust research support as the most effective intervention for high-ability students. Whereas talent search identification and programming are university based, talent search participants receive nearly all of their instruction in K-12 settings, where academic acceleration is less likely to be implemented. In this investigation, a large sample of talent search participants (n = 5,844) were asked questions designed to measure the various ways in which the students study mathematics, science, and language arts (writing and reading) in the K-12 setting. More than two thirds of the study sample reported that they were taught in the regular classroom, learning the same material, at the same level and pace as nongifted peers. The type of curriculum differentiation or program delivery model (e.g., small-group instruction) reported by the students varied according to subject area, with the greatest percentage of reports of differentiated delivery in mathematics. Main effects were found for gender, grade, and ability. Implications for school-based accelerative interventions are presented. (Contains 5 tables and 1 figure.)

Abstract:
The underrepresentation of girls from nondominant backgrounds in the sciences and engineering continues despite recent gains in achievement. This longitudinal ethnographic study traces the identity work that girls from nondominant backgrounds do as they engage in science-related activities across school, club, and home during the middle school years. Building a conceptual argument for identity trajectories, the authors discuss the ongoing, cumulative, and contentious nature of identity work and the mechanisms that foster critical shifts in trajectories. The authors argue that the girls view possible future selves in science when their identity work is recognized, supported, and leveraged toward expanded opportunities for engagement in science. This process yields layered meanings of (possible) selves and of science and reconfigures meaningful participation in science. (Contains 2 tables, 1 figure, and 1 note.)

Abstract:
Exposing students to the application of math and science through a design-based activity can make them more technologically literate and teach integration between the STEM disciplines at an early age. This article discusses an activity that originated as a portion of a green residential house project conducted by the authors with their high school level students. The windmill portion was specifically targeted and broken down by the authors to work with elementary school students studying alternative energy at Kipps Elementary School in Blacksburg, VA. This activity can be completed at the upper elementary level as students enter Piaget's concrete operational stage and possess the fine motor skills to complement their logical thinking. This activity shows that teachers at any level, but specifically Grades 3-6, can be innovative in adapting lessons to promote technological literacy.
