Exploring Retrieval Difficulties And Self-Confidence In An Assessment Of General Chemistry Students, Karen Julian, Morgan Balabanoff

The Cardinal Edge

Developing self-assessment skills is an important aspect of learning. Framed by assessment developed for the year-long sequence of general chemistry, students were asked to rate their ability to answer conceptual questions. Using cognitive interviews, this study revealed that people rely on a range of characteristics other than content knowledge to assess their confidence, including doubt, retrieval difficulty, and test-taking methods. These findings imply that more explicit instruction may be required to encourage correct self-assessment. Students can develop their metacognitive skills and calibrate their perceived ability by completing examinations meant to emphasize content knowledge gaps.

Organic chemistry is accepted as a crucial part of science higher education funneling students into many career opportunities such as pharmaceuticals, biotechnology, and medical industries. Students attempting organic chemistry courses in higher education are among a plethora of majors including biology, chemistry, health science, and engineering. However, organic chemistry as a course has stayed fairly stagnant for the past 50 years. Students in this course typically resort to rote-memorization and often regard the course itself as insurmountable. To answer the decreasing retention rates seen across the United States, the research revolving around organic chemistry knowledge and teaching methodologies has increased …

Specifications Grading Has Improved My Courses!, Bruce J. Heyen

Scholar Week 2016 - present

Specifications grading is a way of "restoring rigor, motivating students, and saving faculty time" as stated in the title of Linda Nilson's book promoting this method. While there are many variations across disciplines, I will present how I am using specifications grading in my Organic Chemistry courses. I label course objectives as essential or non-essential, and students must master these with a quiz score of 80% or greater to obtain the points. Students are allowed multiple attempts to master course objectives.

This thesis considers the use of PBL and describes the implementation of a PBL unit in a rural Maine 11th grade chemistry classroom. The thesis aims to better understand the impact PBL has on students’ content learning and additional skills acquired through the PBL learning process. Along with …

Identifying Sources Of Anxiety In An Introductory Online Undergraduate Chemistry Course, Emily Faulconer, John C. Griffith

Publications

Learning chemistry in an online environment may have multiple sources of anxiety for students, including chemistry anxiety, math anxiety, computer anxiety, and trait anxiety (personality attribute of proneness to experience anxiety). While previous research has explored relationships between math and chemistry anxiety in a traditional setting, no studies have explored these anxieties in the online modality. Survey data were collected using existing scales (some with minor modifications), with a response rate of 31%. The scales used in this study demonstrated strong reliability. Highest sources of anxiety for each scale were presented. The perceived ease of use scale score was used …

The Effect Of Interleaved Practice In A High School Chemistry Class, Alex Herrington

Master's Theses & Capstone Projects

Determining practices to produce optimal learning outcomes is a foundational objective for educators. Recent publications have identified the importance of practice sequencing structures (blocked vs interleaved) on learning. While this information has significant value for education, few studies have been conducted in authentic educational environments. This action research involved high school chemistry students (n=25) completing a practice assignment covering mole-mass conversions. One group practiced these problems in a blocked organization while the other was interleaved. Immediately following this assignment, students noted their completion time and rated their perceived difficulty. Three days later, students were given an unannounced interleaved assessment of …

The Relationship Between Spatial Ability And The Conservation Of Matter In Middle School, Merryn Cole, Jennifer Wilhelm, Briana Marie-Mcknight Vaught, Corinne Fish, Hailey Fish

Science, Technology, Engineering, and Mathematics (STEM) Education Faculty Publications

Research has shown that spatial ability plays a key role in understanding STEM (Science, Technology, Engineering, and Mathematics) content, including chemistry. Conservation of Matter (CoM) is an essential but challenging topic for chemistry students of all ages to grasp; it is often taught in a way where students memorize it but do not learn what it means conceptually. This research explored the relationship between understanding spatial ability and conceptual understanding of CoM in middle school students. CoM was examined in two ways using the Conservation of Matter Assessment (CoMA): through questions on conservation of atoms and the conservation of mass. …

Lessons Learned In Designing Active Learning Modules For The Stem Classroom, Anna M. Christianson

Pedagogicon Conference Proceedings

For students to become real partners in their education, they must shift from a model of passive absorption of knowledge to one of active participation in constructing knowledge. To encourage this shift, I have designed a variety of active learning modules for my introductory chemistry classes, from short participation polls to full-length case studies. When well-implemented, in-class activities can be a valuable experience for students to practice applying their knowledge with instructor guidance. In this report, I will share both successes and challenges encountered in designing student-friendly active learning modules in an introductory science course.

Florida Science: The Science That Makes Florida Different, Terence W. Cavanaugh

Secondary Level Resources

This book was created to assist students with their understanding of how science occurs in Florida. When teaching science or any subject it’s important to remember to begin with the concrete and then move to the abstract. I have found that it has helped my students when I begin by teaching science concepts in a concrete manner and expand from there. For example, when I taught about topographic maps, the students were much more successful in their learning when I started with local topographic maps that included the school and the surrounding area than with places that had mountains or …

The study involved two course pairs: one section of each course delivered in the traditional non-integrated manner and a second pair of sections that were integrated across the chemistry and biology disciplines in both the scope and sequence of the …

Spatial Reasoning And Understanding The Particulate Nature Of Matter: A Middle School Perspective, Merryn L. Cole

Theses and Dissertations--Education Sciences

This dissertation employed a mixed-methods approach to examine the relationship between spatial reasoning ability and understanding of chemistry content for both middle school students and their science teachers. Spatial reasoning has been linked to success in learning STEM subjects (Wai, Lubinski, & Benbow, 2009). Previous studies have shown a correlation between understanding of chemistry content and spatial reasoning ability (e.g., Pribyl & Bodner, 1987; Wu & Shah, 2003: Stieff, 2013), raising the importance of developing the spatial reasoning ability of both teachers and students.

Few studies examine middle school students’ or in-service middle school teachers’ understanding of chemistry concepts or …

Development Of Accessible Laboratory Experiments For Students With Visual Impairments, Kc Kroes, Daniel Lefler, Aaron Schmitt, Cary A. Supalo

Journal of Science Education for Students with Disabilities

The hands-on laboratory experiments are frequently what spark students’ interest in science. Students who are blind or have low vision (BLV) typically do not get the same experience while participating in hands-on experiences due to accessibility. Over the course of approximately 9 months, common chemistry laboratory experiments were adapted and field tested for use in a residential school for the blind. These adaptations most commonly used a SciVoice Talking LabQuest and associated sensors, as well as other tactile methods.
