Exploring Retrieval Difficulties And Self-Confidence In An Assessment Of General Chemistry Students, Karen Julian, Morgan Balabanoff Sep 2023

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.

Tools Enabling A Student Who Is Blind In A Liberal Arts Chemistry Laboratory Course, Jessica Michael, H. David Wohlers Aug 2019

Tools Enabling A Student Who Is Blind In A Liberal Arts Chemistry Laboratory Course, Jessica Michael, H. David Wohlers

Journal of Science Education for Students with Disabilities

Chemistry laboratories ordinarily involve a number of visual observations and require qualitative and quantitative explanations of these observations. A student with blindness at Truman State University successfully completed the laboratory portion of the nonmajors liberal arts chemistry course with the assistance of a senior undergraduate chemistry education major, the guidance of a chemistry professor with blindness, and a variety of alternative laboratory methods. Volumes were measured using a notched syringe or the graduated cylinder pipet technique. Changes in color were measured by a Color Analysis Laboratory Sensor (CALS) and a Submersible Audio Light Sensor (SALS). Balance and Vernier probe measurements …

The Sals App: Making Chemistry Accessible With Ios Devices, Rosanne Hoffmann

Journal of Science Education for Students with Disabilities

A new version of SALS (Submersible Audible Light Sensor) consists of a wireless light-detecting probe, Bluetooth ® connected to the iOS SALS App. As in previous versions of SALS, changes in detected light are converted to changes in sound, the latter now rendered with iPhone or iPad audio. The SALS probe assists the student with visual impairment in a variety of science activities, including those involving liquids. For example, when the SALS probe is placed in a reaction vessel, changes in light intensity caused by a chemical reaction or color indicator change are converted to changes in tone in real …


Enhancing Interdisciplinary Attitudes And Achievement Via Integrated Biology And Chemistry, Ying Guo, Pat Uelmen Huey Dr., David P. Pursell May 2017

Enhancing Interdisciplinary Attitudes And Achievement Via Integrated Biology And Chemistry, Ying Guo, Pat Uelmen Huey Dr., David P. Pursell

Proceedings of the Interdisciplinary STEM Teaching and Learning Conference (2017-2019)

Success in undergraduate biology courses relies upon a firm grounding in chemical principles. We sought to raise students’ awareness of the connection between these two disciplines and to improve their understanding of each by carrying out a pilot project that integrated the curricula of Principles of Chemistry II (CHEM1212K) and Principles of Biology I (BIOL1107K) during the Fall 2016 semester. 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 …


Development Of Accessible Laboratory Experiments For Students With Visual Impairments, Kc Kroes, Daniel Lefler, Aaron Schmitt, Cary A. Supalo Sep 2016

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.


Ambiguity In Speaking Chemistry And Other Stem Content: Educational Implications, Mick D. Isaacson, Michelle Michaels Sep 2015

Ambiguity In Speaking Chemistry And Other Stem Content: Educational Implications, Mick D. Isaacson, Michelle Michaels

Journal of Science Education for Students with Disabilities

Ambiguity in speech is a possible barrier to the acquisition of knowledge for students who have print disabilities (such as blindness, visual impairments, and some specific learning disabilities) and rely on auditory input for learning. Chemistry appears to have considerable potential for being spoken ambiguously and may be a barrier to accessing knowledge and to learning. Educators in chemistry may be unaware of, or have limited awareness of, potential ambiguity in speaking chemistry and may speak chemistry ambiguously to their students. One purpose of this paper is to increase awareness of potential ambiguity in speaking chemistry and other STEM fields …

An Activity Promoting The Practice Of Quantitative Literacy For Pre– And In–Service Teachers Of Mathematics And Science, Timothy L. Sorey, Teri Willard, Duane Sholz

Numeracy

The purpose of this article is to describe a hands-on, laboratory activity that provided pre-service teachers in mathematics and science methods courses, and also some in-service mathematics teachers, with the opportunity to exercise quantitative literacy (QL) skills. The focus of the activity is electrical resistance, more particularly the resistance (in ohms) that is painted on small resistors by the use of color-coded bands, one of which is a band for % error. The activity consists of four parts. In the first, student teams familiarize themselves with the code, measure the ohmage of resistors for which the codes are visible, and …

The Inert Gases, R. W. Getchell Feb 1932

The Inert Gases, R. W. Getchell

Science Bulletin

Nitrogen gas is lazy. A chemical revolution may enlist and lead away nearly every other element and compound in the air, but nitrogen will stay at home and refuse to become excited. Less than forty years ago, Lord Rayleigh in England made use of this characteristic by removing the other components of the air and collecting the remaining supposedly pure nitrogen in order to study it.


We, The Jury, R. W. Getchell Sep 1930

We, The Jury, R. W. Getchell

Science Bulletin

Iowa high schools may justly be proud of their chemistry courses and of their chemistry teachers. The state ranks low in the number of schools offering this science but high in the quality of its teaching staff. One sure criterion of instructional efficiency is growth - a growth based upon the frank recognition of mistakes and intelligent effort to correct them.


Chemical Lecture Experiments, R. W. Getchell May 1930

Chemical Lecture Experiments, R. W. Getchell

Science Bulletin

Lecture experiments demand more time, require higher technical skill, and afford greater pupil interest than any other phase of chemistry teaching. As a corollary, we may add that they are most neglected, but if you name the teachers who are noted for their interesting, instructive, and skillful classroom demonstrations, you are calling the roll of chemistry teachers of the first rank.


Science Minded, Harold E. Murphy Nov 1929

Science Minded, Harold E. Murphy

Science Bulletin

When we are trying to be "air minded " and "peace minded" why not go a little further and be 'science minded"? The aeronautic field has as its champion, Colonel Lindberg; the Peace Federation has as its champion, Ishbell McDonald; but where is the youthful champion of the field of chemical science? In this day of scientific advancement, a champion is surely needed to bring t h e achievement of chemical science to the people. Someone has said, "Science is the Creator's chest of tools. Human progress is man's learning to use these tools."


Professional Growth, R. W. Getchell Apr 1929

Professional Growth, R. W. Getchell

Science Bulletin

The first class provides bits of scientific information which can be interspersed in class discussions. Such items will add interest to the class work and may indicate new and modern uses for chemical substances and appliances. They are found in such publications as Popular Science Monthly. The second class of articles are indispensable to good teaching.


Professional Growth, R. W. Getchell Mar 1929

Professional Growth, R. W. Getchell

Science Bulletin

An official in a small school system was discussing the requirements for a good teacher. "We prefer teachers," he said, "who will outgrow their position in our school." What greater challenge to professional growth could be offered to a teacher in service?


Laboratory Upkeep, R. W. Getchell Jan 1929

Laboratory Upkeep, R. W. Getchell

Science Bulletin

The article last month dealt with reagent bottles. Another problem is met in the proper care of iron ware - the special target of the corrosive laboratory fumes. To supply the pupil with rusty, oxide encrusted metal equipment is to encourage careless, slovenly work. An annual "paint day" is essential.


Laboratory Upkeep, R. W. Getchell Dec 1928

Laboratory Upkeep, R. W. Getchell

Science Bulletin

Proper care of the laboratory is the phase of the high' school chemistry teacher's task most apt to be neglected. This and later articles will point out some of the " little things that make perfection."
