High School Students’ Learning and Perceptions of Phylogenetics of Flowering Plants

Basic phylogenetics and associated “tree thinking” are often minimized or excluded in formal school curricula. Informal settings provide an opportunity to extend the K–12 school curriculum, introducing learners to new ideas, piquing interest in science, and fostering scientific literacy. Similarly, university researchers participating in science, technology, engineering, and mathematics (STEM) outreach activities increase awareness of college and career options and highlight interdisciplinary fields of science research and augment the science curriculum. To aid in this effort, we designed a 6-h module in which students utilized 12 flowering plant species to generate morphological and molecular phylogenies using biological techniques and bioinformatics tools. The phylogenetics module was implemented with 83 high school students during a weeklong university STEM immersion program and aimed to increase student understanding of phylogenetics and coevolution of plants and pollinators. Student response reflected positive engagement and learning gains as evidenced through content assessments, program evaluation surveys, and program artifacts. We present the results of the first year of implementation and discuss modifications for future use in our immersion programs as well as in multiple course settings at the high school and undergraduate levels.

Just as beginning students in geography need to be taught how to read maps, so beginning students in biology should be taught how to read trees and to understand what trees communicate. O’Hara (1997 , p. 327)

     

High School Students’ Perceptions of Evolution Instruction: Acceptance and Evolution Learning Experiences

Evolution is an important and sometimes controversial component of high school biology. In this study, we used a mixed methods approach to explore students’ evolution acceptance and views of evolution teaching and learning. Students explained their acceptance and rejection of evolution in terms of evidence and conflicts with religion and authority. Students largely supported the teaching of evolution and offered several reasons for its inclusion in high school biology. Students also offered several suggestions for improving evolution instruction. Evolution acceptors’ and rejecters’ views of evolution teaching and learning differed in a number of respects, and these differences may be explained using border crossing as a theoretical lens. Relevant implications for evolution instruction are discussed.     

Upper High School Students’ Understanding of Electromagnetism

Although electromagnetism is an important component of upper secondary school physics syllabuses in many countries, there has been relatively little research on students’ understanding of the topic. A written test consisting of 16 diagnostic questions was developed and used to survey the understanding of electromagnetism of upper secondary school students in Turkey (n = 120) and England (n = 152). A separate test consisting of 10 questions on the visualization of spatial rotation was used to investigate the hypothesis that students’ ability to visualize three‐dimensional situations from two‐dimensional representations might influence learning of electromagnetism. Many students’ responses showed misunderstandings and inconsistencies that suggested they did not have a coherent framework of ideas about electromagnetism. Common errors included confusing electric and magnetic field effects, seeing field lines as indicating a “flow”, using cause–effect reasoning in situations where it does not apply, and dealing with effects associated with the rate of change of a variable. Performance on the spatial rotation test was, however, only weakly correlated with performance on the electromagnetism questions. The findings suggest the need to develop teaching strategies that help students to visualize magnetic field patterns and effects, and assist them in integrating ideas into a more coherent framework.     

Students’ Perceptions of High School Science: What has Changed Over the Last Decade?

This paper presents comparative questionnaire data from three different samples of Australian high school students in an attempt to see if anything has changed in relation to how they perceive the science they experience in the compulsory years of secondary school (grades 7–10). Questionnaire data were obtained from 1,585 high school students in 2011 and 2,016 students in 2005 and findings are compared with those reported in a national report (Goodrum et al. 2001). Results show significant increases in the frequency with which students report that their science teacher takes notice of their ideas and in the use of computers and the Internet. There have also been changes regarding the rapid provision of feedback, the use of understandable language by teachers and the contextualisation of the new work in terms of work already covered. Little appears to have changed, however, in relation to the teacher-directed pedagogies employed to teach science where there appears to be a higher incidence of copying notes and fewer opportunities for students to investigate topics in which they are interested. The findings suggest that while there have been some positive changes, there are still many students who indicate that the science they experience in secondary school is irrelevant to their everyday life and to their future. It seems that the curiosity and wonder one would hope is associated with studying science is missing for a large proportion of students. It is clear that further actions need to be undertaken to transform this continuing situation.     

Connecting Soccer to Middle School Science: Latino Students’ Passion in Learning

Building on a pedagogical model designed to support the teaching and learning of the language of science investigation practices with middle school emergent bilingual learners, we developed a series of soccer and science investigations to promote interest and engagement in science learning. We used assemblage theory to study how students engaged in and acted within this bilingual curriculum situated in an afterschool soccer practice context. We found that soccer, a passion for several Latino students, can be used as a cultural tool for science teachers to support the emerging bilingual students’ learning process. Implications for educators and researchers considering ways of integrating diverse students’ cultural practices and passions with culturally sustaining pedagogies for science teaching and learning are discussed.     

High School Students’ Motivation to Learn Mathematics: The Role of Multiple Goals

Using a sample of 310 Year 10 Chinese students from Hong Kong, this survey study examined the effects of multiple goals in learning mathematics. Independent variables were mastery, performance-approach, performance-avoidance, and pro-social goals. Dependent variables included perceived classroom goal structures, teacher’s support, learning motives and strategies, attitudes, and grade aspiration. Based on regression and cluster analyses, this study found convergent evidence supporting the benefits of adopting additional adaptive goals alongside mastery goals. Regression analyses located significant interaction between pro-social goals and mastery goals in predicting higher levels of positive learning attitudes and lower levels of surface learning motives. Cluster analyses confirmed that students endorsing pro-social goals, performance-approach goals and mastery goals in their goal profiles had an adaptive pattern of perceptions, use of strategies, learning motives and grade aspiration in mathematics.     

High School Students’ Understanding of the Human Body System

In this study, 120 tenth-grade students from 8 schools were examined to determine the extent of their ability to perceive the human body as a system after completing the first stage in their biology curriculum - “The human body, emphasizing homeostasis”. The students’ systems thinking was analyzed according to the STH thinking model, which roughly divides it into three main levels that are arranged “pyramid” style, in an ascending order of difficulty: 1. Analysis of system components—the ability to identify the components and processes existing in the human body system; 2. Synthesis of system components—ability to identify dynamic relations within the system; 3. Implementation—ability to generalize and identify patterns in the system, and to identify its hidden dimensions. The students in this study proved largely incapable of achieving systems thinking beyond the primary STH level of identifying components. An overwhelming majority if their responses corresponded to this level of the STH model, further indicating a pronounced favoring of structure over process, and of larger, macro elements over microscopic ones.     

Communities of Caring: Developing Curriculum That Engages Latino/a Students’ Diverse Literacy Practices

This study investigates the learning and work of a community of practice that engaged in a specific inquiry around family/community literacy and the development of a culture of caring that would connect family/community/school literacies in ways that allowed their mostly Latino/a students to develop positive student identities, enhanced personal connections to their peers, and stronger experiential responses to literacy instruction.     

Iraqi Refugee High School Students’ Academic Adjustment

Many Iraqi refugee students in the United States suffer from posttraumatic stress disorder (PTSD) as well as acculturation stresses. These stresses often create challenges for their integration into U.S. schools. The project explored risk factors such as the length of educational gaps in transit, PTSD, and separation and marginalization acculturation, as well as protective factors such as resilience, self-esteem, and integration and assimilation. We conducted bivariate correlations and multiple regression to examine the relationship between factors and predicting school adjustment using variables among 100 Iraqi refugee high school students in the Detroit area. The results showed that the educational gaps (negatively), and assimilation and resilience (positively), are the strongest predictors for school adjustment. PTSD incurred by Iraqis as a result of events experienced before and during their migration from Iraq are related to their self-esteem and separation acculturation, while educational gaps are related to their marginalization as well as to their integration.     

Relationships between High School Chemistry Students’ Perceptions of a Constructivist Learning Environment and their STEM Career Expectations

Considerable attention has been devoted to factors affecting the persistence of women and historically underrepresented ethnic groups in their science education trajectories. The literature has focused more on structural factors that affect longitudinal outcomes rather than classroom experiences. This exploratory survey study described relationships among high school chemistry students’ perceptions of a constructivist learning environment (CLE) and STEM career expectations. The sample included 693 students from 7 public high schools within the San Francisco Bay Area. Students’ perceptions of a CLE predicted their expectations of entering a science career, but not engineering, computer, health, or mathematics-related careers. When all groups of students perceived the learning environment as more constructivist, they were more likely to expect science careers.     

Students’ English Learning Anxiety in Senior High School

Since 1970s,the research on second language acquisition has been developed with times.The research focus of lLanguage teach ing has shifted from the study of how to teach students to how to learn for students,with particular attention to explore the influence that students’psychological factors such as learning motivation,learning attitude and learning anxiety have on learning outcomes.Among those emotional variables,anxiety is considered to be one of the most critical psychological variables.English classroom anxiety is different from the ordinary classroom anxiety and receives much attention from scholars.Horwiz(1986) pointed out that foreign language anxiety is a unique phenomenon in language learning.In China,English learning in senior high school is a very important period.It is a common phenomenon to see students behaving anxiously in the English class.Therefore,the anxiety in the English class of senior high school de serves attention.This paper will analyze the main reasons of students’anxiety and points out several effectively methods to relieve their anxiety so as to enhance English classroom teaching and learning effect.     

Sociocultural Variables That Impact High School Students’ Perceptions of Native Fauna: a Study on the Species Component of the Biodiversity Concept

This study investigates the influence of school sector (private versus state schools) and student gender on knowledge of native fauna. Our main objectives were (a) to describe the knowledge of high school students from the province of Cordoba, Argentina with respect to native animal species, (b) to determine if any exotic species (introduced or domestic) are considered native, and (c) to analyze the effects of school sector and gender on the students’ knowledge of the native fauna. In total, 321 students aged 15–18 from 14 urban schools (8 state and 6 private schools) were asked to write down ten animals native to Córdoba, Argentina, in a free-list questionnaire. Relative frequencies and Generalized Linear Mixed Models (GLMM) were used to analyze the categorized (animal names) and continuous answers (quantity of responses, number of native animals, etc.), with the 25 most frequently mentioned species showing a predominance of native ones, of which “Puma” (Puma concolor) and “Andean condor” (Vultur gryphus) were the most prominent. An overrepresentation of mammalian species compared to other classes of chordates was also found, with high school students mentioning native and domestic species higher on the free-list. Using GLMM, we found that school sector had a significant effect on the number of native animals mentioned at both national and local levels, and on domestic and mixed species. Finally, male students mentioned more species and more native animals than their female counterparts. These findings were interpreted and discussed in light of sociocultural and traditional ecological knowledge theories, from which several implications arose related to research and practice.

Language Learning Beliefs:A Survey of Chinese High School Students

1. Introduction To our knowledge, students come to the class with their own mini-theories about language learning. Those mini-theories are called language learning be- liefs (LLBs) by Horwitz (1987) and viewed as a com- ponent of metacognitive knowledge in cognitive psy- chology (e.g., Flavell, 1979). Studies show that LLBs exert either positive or negative effects on learning process. Therefore, it is quite necessary to take a com- prehensive investigation into the beliefs held by lan- gu…     

Students’ Learning Experiences in an Early College High School

Early College High Schools (ECHS) are at the forefront of high school reform embodying the principles of rigor, relationship, and relevance. This study examines students’ learning experiences in the context of relationships and rigor at an ECHS. Specifically, I investigate factors that influence students to attend an ECHS, what they attribute to their academic success, and the challenges they experience. I draw upon data from individual and focus group interviews with students at one 3-year-old ECHS in southeastern North Carolina.
