An Activity Aimed At Improving Student Explanations Of Biological Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez

PIBERG Instructional Innovation Materials

This document is intended for use by instructors and their students. The activity contains steps to introduce students to the MACH model involving analyzing and discussing explanations about biological mechanisms. Initially, students read modified articles about biological mechanisms during class, although instructors may prefer to assign readings outside of class before the activity. During the activity, students are required to analyze the readings for evidence of research methods, analogies, context, and mechanisms. In so doing, students learn how to integrate the information pertaining to each of the MACH model components into a coherent explanation about their biological mechanism. After performing …

A Tetrahedral Version Of The Mach Model For Explaining Biological Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez

PIBERG Instructional Innovation Materials

This document is intended for both instructors and students. Modified from the original MACH model this version, once cut and folded, creates a tetrahedral model that can conveniently be used as a teaching and learning tool to inform and guide students on how to write expert quality explanations of biological mechanisms. Each vertex of the tetrahedron represents a component of the model namely, Methods, Analogy, Context, and How. For a coherent and complete explanation about molecular mechanisms, it is important to integrate information pertaining to all four components of the model. The tetrahedral MACH model has been tested in both …

Misalignments: Challenges In Cultivating Science Faculty With Education Specialties In Your Department, Seth D. Bush, Nancy Pelaez, James A. Rudd Ii, Michael T. Stevens, Kimberly D. Tanner, Kathy S. Williams

PIBERG Publications

Science Faculty with Education Specialties (SFES) are increasingly being hired across the United States. However, little is known about the motivations for SFES hiring or the potential or actual impact of SFES. In the context of a recent national survey of US SFES, we investigated SFES perceptions about these issues. Strikingly, perceptions about reasons for hiring SFES were poorly aligned with perceptions about potential and actual contributions reported by SFES themselves, and the advice they extended to beginning SFES was varied. While preparation of future teachers and departmental teaching needs were common reasons offered for SFES hiring, the potential and …

In addition, this study sought to examine demographic factors and find their relation, if any, to these teaching beliefs, as well as explore topics that may be useful in the future to helping community colleges science instructors’ curricula and beliefs come together and work in unison. To do this, the study built on the foundation laid by Sampson et al., in their creation of the Beliefs about Reformed Science Teaching and …

Demographics, Persistence, And Academic Performance: A Logistic Regression Analysis Of Who Chooses To Enter The Mathematics And Science Teaching Pipeline, Esther Joseph

FIU Electronic Theses and Dissertations

As of 1999, high school teachers without majors in their subject areas number 37% of biology teachers, 59% of physical science teachers, and 60% of mathematics teachers. These discouraging statistics grow more extreme in middle schools and high poverty public high schools, especially regarding mathematics and physical sciences instruction. The statistics are especially worrisome given the strong correlation between thorough teacher subject matter preparation and higher student performance. Unfortunately, the literature is limited in terms of a direct comparison between mathematics and science majors and individuals who become mathematics and science teachers. This study was undertaken to add to the …

A Novel Approach To Using Personal Response Systems And Diagrams To Foster Student Engagement In Large Lecture: Case Study Of Instruction For Model-Based Reasoning In Biology, Johanna M. Fitzgerald

Doctoral Dissertations

At UMass Amherst a method of personal response system (clickers) use in large lecture biology called Guided Application of Model-based Reasoning (GAMBR) has been designed to give students experiences in reasoning like expert biologists: In large lecture biology many instructors appear to use clickers mainly as a quizzing and attendance tool. Less well documented and examined are uses of clickers to facilitate cognitive engagement in learning scientific models and skills. In GAMBR, clicker questions ask students to apply and perturb biological models; this is designed to engage them in model-based reasoning. In an attempt to understand such a course, an …

The Effects Of Emotive Reasoning On Secondary School Students' Decision-Making In The Context Of Socioscientific Issues, Wardell Anthony Powell

USF Tampa Graduate Theses and Dissertations

The discrepancy between what students are being taught within K-12 science classrooms and what they experience in the real world has been well documented. This study sought to explore the ways a high school biology curriculum, which integrates socioscientific issues, impacts students' emotive reasoning and their ability to evaluate evidence, make informed decisions on contemporary scientific dilemmas, and integrate scientific content knowledge in their reasoning on SSI. Both quantitative and qualitative methods were used to examine differences within and between an SSI treatment group and a comparison group as well as individual differences among students' responses over a semester of …

Improving The Efficacy Of Web-Based Educational Outreach In Ecology, Gregory R. Goldsmith, Andrew D. Fulton, Colin D. Witherill, Javier F. Espeleta

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Scientists are increasingly engaging the web to provide formal and informal science education opportunities. Despite the prolific growth of web-based resources, systematic evaluation and assessment of their efficacy remains limited. We used clickstream analytics, a widely available method for tracking website visitors and their behavior, to evaluate 60,000 visits over three years to an educational website focused on ecology. Visits originating from search engine queries were a small proportion of the traffic, suggesting the need to actively promote websites to drive visitation. However, the number of visits referred to the website per social media post varied depending on the social …

The Relationship Between Teaching Approaches And Student Science Achievement For Four Racial Groups In Us Eighth Grade Classes, Su Gao

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lower science achievement and substantial racial performance gaps persist among students in the US. In the current reform of science teaching, inquiry-based science teaching is assumed effective in improving all student science learning in both scientific content and process and reducing learning gaps across racial groups. Conversely, traditional didactic science teaching is believed to be the most popular and has contributed to lower science achievement and the racial gap. These two assumptions, although central to science teaching reforms, cannot be empirically sustained in the existing literature on science teaching. Framed through the theoretical perspectives of inquiry-based instruction and culturally relevant …

Describing Students' Talk About Physical Science Phenomena Outside And Inside The Classroom: A Case Of Secondary School Students From Maragoli, Western Region Of Kenya, Grace Nyandiwa Orado

Dissertations - ALL

Because of cultural and linguistic influences on science learning involving students from diverse cultural and linguistic backgrounds, calls have been made for teachers to enact teaching that is sensitive to these students' backgrounds. However, most of the research involving such students has tended to focus on students at elementary grade levels from predominantly two linguistic backgrounds, Hispanic and Haitian Creole, learning science concepts mainly in the life sciences. Also, most of the studies examined classroom interactions between teachers and the students and among students. Not much attention had been paid to how students talk about ideas inherent in scientific phenomena …

Ideology And Interdisciplinary Science Graduate Education Reform, Benjamin Harrison Allen

Masters Theses

Over the past few decades, a variety of science education reform publications have emerged from both public and private entities, alongside graduate programs established to provide training for integrating multiple disciplines in research activities. Several documents concerning federal education policy have explored the socioeconomic impacts of reforming graduate education in the sciences and have made recommendations for funding interdisciplinary traineeship programs at U.S. universities. On the other hand, much of the current academic literature concerning interdisciplinary graduate science education considers the subject from functionalist perspectives, aiming to contribute best practices for assessment and curricular programming. In contrast to both of …

Multilevel Analysis Of Fifth Grade Teacher Qualifications And Their Students' Science Achievement, Nigel Noll

ETD Archive

The No Child Left Behind Act mandated every student be taught by a highly qualified teacher (HQT). Criteria to determine if teachers meet the HQT mandate fail to account for differences in grade levels, subject areas, and student demographics. This study posited that the relationship between measures of teacher quality and student achievement vary according to contextual factors. Fifth grade is unique in that it marks students' transition from upper elementary to middle school grade levels thus, fifth grade may be classified as either an upper elementary grade or middle grade. This classification determines HQT requirements specifically, classification affects the …

Peer-instruction has been shown to have a very positive effect on students’ engagement and learning. PeerWise is a web-tool designed to allow peer-tutoring between students within a large class group. Students can write, answer and discuss Multiple Choice Questions (MCQs) based on their work in-class. It is low-cost and low-maintenance software which has become increasingly popular across many subject disciplines as a method to introduce a peer-tutoring aspect to course work. In this study we introduce PeerWise as a form of continuous assessment to a wide and varied cohort of science students (N=509) across disciplines, undergraduate years, levels (certificate to …

Meaningful Encounters: Creating A Multi-Method Site For Interacting With Nonhuman Life Through Bioarts Praxis, Donna Franklin

Theses: Doctorates and Masters

This research advocates a multi-method approach to bioarts praxis, reflexively and critically questioning the contemporary contexts that frame our engagement with nonhuman life. In doing so, the research aims to generate further community engagement with nonhuman life and the environment, and engender critical discourse on the implications of developing biotechnologies.

Hegemonic institutions influence the way culture is produced and how information is constructed and understood. Habermas (1987) suggests that these institutions will inevitably influence the individual’s lifeworld as they shape lived experience through the process of systemic colonisation. I assert that this process also shapes how individuals engage with or …
