It’s that time of year…

As the end of the academic year approaches, stressed students work furiously on end-of-term projects and prepare for final exams. For faculty and teachers, another stress looms large – students’ course and teacher evaluations.

A new legislative proposal in Iowa has brought the use of student evaluations to the forefront again.  A recent NPR article discusses the bill and it’s potential impact: http://www.npr.org/blogs/ed/2015/04/26/401953167/what-if-students-could-fire-their-professors

In a nutshell, the article supports a widely held opinion that although course evaluations play a role in measuring some areas of teaching effectiveness, they really don’t accurately identify good teaching. Other methods should be employed – one of which has to do with reviewing the materials that professors use to create their classes. Materials, such as syllabi, handouts, exams, samples of students’ work, video recordings of class, and use of technology, are all familiar tools that teachers use to maintain student engagement, encourage learning, and reinforce retention.

Which brings us to WebAssign – a technology solution that many professors have relied on for years to support successful learning outcomes. In fact, in a recent student survey of WebAssign users, 85% of respondents stated that WebAssign positively impacted their exam grade*. We wonder…

  • Do your students include your use of WebAssign (or any technology, for that matter) in their evaluation of your course?
  • Would they award you positive points, or negative, for your practices of assigning online homework or scheduling online testing?
  • Does the student survey response sound like your students? And would they attribute their success to how you have employed WebAssign in your classroom?

It sure seems like technology plays a large role in the student classroom experience these days. Professors who successfully integrate that technology in their curriculum could have an advantage when it’s that time of year again.

Green Chemistry Primer – Reaction Efficiency, Percent Yield, and Atom Economy

Happy Earth Day!

Chemistry often gets a bad reputation when it comes to keeping our Earth green and healthy. “Chemicals” are added to food, they are in our water, they are referred to in association with being bad or harmful. While biology usually gets the nod as the “green” science, the “green chemistry” movement has given form to principles for improving chemical processes – such as using environmentally friendlier solvents, or reactions in which catalysts reduce energy expenditure. One key aspect introduced at the general chemistry level is reaction efficiency.

Whether chemical reactions are used in industry or the academic laboratory, a key factor is the efficiency of a reaction. In fact, millions of dollars of research funding has gone into improving the efficiency of reactions. In this article, we give a brief overview of two concepts in measuring reaction efficiency – percent yield and atom economy.

Students of general chemistry commonly encounter percent yield calculations – determining how much product was obtained in the lab relative to the amount expected in perfect reaction conditions.

For example, if you generated 15.33 g of product, but expected 17.41 g based on your starting amounts, you would have this percent yield:

wordpress chem paper 2

Here’s a baking analogy: You follow a recipe for 2 dozen cookies, but your kids eat enough cookie dough that you end up with just 22 cookies, or roughly a 92% percent yield.

In addition to percent yield, there is a second measure of reaction efficiency – atom economy.  Atom economy measures the percentage of the mass of products theoretically produced by a reaction versus the desired goal product. This metric of reaction efficiency differs from percent yield in that it is based on the theoretical reaction – not on lab data. In essence, atom economy is how much extra “stuff” you create that you don’t want – even under perfect reaction conditions. Thus, let’s say we were trying to create “G” in the following reaction:

E and J are byproducts of the reaction – we have created materials that we don’t need. To calculate atom economy, we need the molar masses of the products, as described below:

wordpress chem paper 4

In our example above, we have molar masses of E as 44 g/mol, G as 78 g/mol, and J as 18 g/mol, we would calculate atom economy as:

These are the basics of two metrics of reaction efficiency. If you are interested in giving these a try, search for assignment Reaction Efficiency (Assignment ID # 7097680) in WebAssign, which offers a few questions. Beyond this, you can learn more about the “12 Principles of Green Chemistry,” by Paul Anastas and John Warner.

How Collaboration is Just a Modern LMS Away

Check out this article that was recently published in eCampus News. It was written by WebAssign user Michael Lafreniere, an associate professor of environmental engineering technology and mathematics at Ohio University – Chillicothe. Michael will also be presenting at our WebAssign Users Group Meeting on June 25-26. Register today to hear him and other professors talk about teaching, learning, and using WebAssign.

Developing “collaboratories” in mathematics thanks to multi-tooled LMS’

Today’s colleges and universities are quickly turning to alternative pathways to traditional teaching and learning approaches, especially for core courses such as developmental mathematics and algebra—and collaboration enabled through modern Learning Management System (LMS) functionality may be one way to accomplish this rejuvenation.

Leveraging today’s key methods and technologies can create collaborative spaces that enhance student learning and outcomes. A teacher can recapture time spent on traditional lecture and create opportunities for exploration of concepts that lead to increased student engagement and mastery level learning—all while accommodating individual student learning pace variations and asynchronous learning.

LafreniereThe technology to help accomplish this form of pedagogy can be brought together in what is being called the “Collaboratory Approach” or simply “Collaboratory.” The term collaboratory is credited to William Wulf for interacting and sharing via software as early as 1989 (Wulf, 1993).

Today, the software is a web-based application commonly known as an LMS. With an appropriate LMS, video delivery, conferencing integration, and white board integration with digital inking capabilities, a teacher can collaborate with colleagues and students through the broadcast of synchronous instruction and learning activities online and in-class. The teacher can facilitate collaborative, shareable, personalized note-taking spaces, as well as track student engagement across multiple sections—class and student level insights that assist the teacher much like intentional formative assessment.

At the end of the course, the same data collection can be used in the creation of student portfolios of learning outcomes, which are ideal for course and program improvement, as well as, accreditation.

The goals of an LMS-enabled collaboratory, specifically for developmental mathematics and college algebra include the ability for online learning so that every student can “come to the board” without ever leaving their seat (or coming to campus).

Which means a STEM-proficient online assessment system

Online assessment is a primary driver in the design of this collaboratory approach, given the high effect size of improvement for effortful practice with testing (Brown, Roediger, & McDaniel, 2014; Hattie & Yates, 2014).

For STEM courses like mathematics that come with a significant reliance of symbolic characters, a system that can accept and assess such information provides valuable fidelity to the discipline, time savings, and a greater volume of student engagement.

WebAssign is a great online assessment system, because it affords the highest symbolic and mathematical fidelity needed for student engagement beyond the standard assessment (e.g., types like multiple choice and true/false). It also comes with high-fidelity symbolic capabilities from Maple, Mathematica, and MATLAB—along with embedding capabilities that enable integration of a variety of publisher’s e-content. This e-content can incorporate technical simulations, e-book materials, and student learning support tools like “Watch it” videos; all applications pertinent to learning mathematics, physics, chemistry, and engineering.

The WebAssign online assessment system also serves as the hub of activity through which students engage and collaborate on items like homework, in class activities, quizzes, exams, video lectures, simulations, and problem-solving.

CollaborationThe ability to write and share

Second to the assessment system in the collaboratory LMS approach is a need to write by students and teacher using digital ink, given the benefits known (Mueller & Oppenheimer, 2014). OneNote, DyKnow, or PencilPad can be used to connect teacher and students’ digital writings with others during engagement activities where symbolic mathematical representations are crucial for increasing the mathematical fidelity of their conceptual understanding.

Problem-solving can be shared in real-time, whether a student is present in-class or attending online, through the use of digital ink. Each student is “coming to the board” to contribute and share their approach in problem solving. This conveyance of digital notes from the teacher and students’ collaboration is shared and saved for all in real-time.

Being able to couple tools like PencilPad and DyKnow on an LMS, a teacher can also ascertain the cognitive fidelity of the student’s work via a recording of the digital inking activity. For example, whether sequences are correct from start to finish or filled with intermittent “false starts” or “tangential efforts,” the writing, erasing, and writing is all there for the teacher to evaluate.

In WebAssign, data collection on a student’s digital writings now includes assessment and insights at the question-, assignment-, and class-level with both quantitative and qualitative data types. Educators can see how much a student writes as a measure of engagement (Kamin, Capitanu, Twidale and Peiper, 2008), as well as taking what a student digitally writes and analyze it for correctness via computer algorithms (Hatfield, 2010). Two such promising tools are FluidMath, and MyScript.

A means to flip

Flipped delivery of lectures is often used in the collaboratory approach. To ensure student engagement, as well as provide the teacher with formative assessment data, the flipped delivery of lectures is embedded in WebAssign using such online tools as YouTube or EdPuzzle.

This monitoring and assessing of student lecture viewing provides key mid-level data to reduce misconceptions and develop greater conceptual understanding–leading to greater gains in disciplines like mathematics. Given the time savings from flipped delivery of lectures, a teacher can collect and analyze student writing with digital assessment capabilities or good ol’ fashion “by hand.”

Pooling capability for high stakes

Since class time is spent on concept development and building procedural fluency from these concepts, the LMS should help the teacher build questions (to occur in initial assignments, through exams, and culminating on a final exam) around material learned. From this, mastery of the content by a student (or whole class) can be tracked and displayed in the collaboratory.

As for high-stakes assessments such as module or chapter exams, these are offered in a campus testing center under proctored conditions. Exams can be taken multiple times in this format to further promote mastery learning. Given the randomization and pooling capabilities of a modern LMS, students get a greater range of questions tied to concepts, which can significantly reduce the possibility of academic misconduct.
