One of the many transitions that occurred while moving the Journal editorial offices from Austin to Madison was the unification of the WWW sites of the Journal and JCE Software into JCE Online. Since that time JCE Online has provided several valuable resources to the chemistry education community. With the introduction of JCE Online+ (see below), we have expanded these resources and have plans to expand them even further. We thought that the Journal readership might like to know what is available to them at JCE Online. That's what this new column will do each month. JCE Online is divided into several areas. Each constituent part maintains an area at JCE Online: this Journal, JCE Software, JCE Internet, and JCE Books. There also is an area that lists Chemical Education Happenings and an area that contains information About JCE.

As I write this, JCE Online is in the middle of being redesigned to make it a more usable resource. By the time you read this, the typical online page for articles of this Journal will look like Figure 1. The page has five main features:

The Features area of JCE Online is now readily accessible through a single click from our home page. In the Features area each column is linked to its own home page. These column home pages also have links to them from the online Journal Table of Contents pages or from any article published as part of that feature column. Using these links you can easily find abstracts of additional articles that are related by topic. Of course, JCE Online+ subscribers are then just one click away from the entire article. Finding related articles is easy because each feature column "site" contains links to the online abstracts of all the articles that have appeared in the column. In addition, you can find the mission statement for the column and the email link to the column editor that I mentioned above. At the discretion of its editor, a feature column site may contain additional resources. As an example, the Chemical Information Instructor column edited by Arleen Somerville will have a periodically updated bibliography of resources for teaching and using chemical information. Due to the increase in the number of these resources available on the WWW, it only makes sense to publish this information online so that you can get to these resources with a simple click of the mouse. We expect that there will soon be additional information and resources at several other feature column sites. Following in the footsteps of the Chemical Information Instructor, up-to-date bibliographies and links to related online resources can be made available. We hope to extend the online component of our feature columns with moderated online discussion forums. If you have a suggestion for an online resource you would like to see included, let the feature editor or JCE Online (jceonline@chem.wisc.edu) know about it. JCE Internet Features JCE Internet also has several feature columns: Chemical Education Resource Shelf, Conceptual Questions and Challenge Problems, Equipment Buyers Guide, Hal's Picks, Mathcad
National Chemistry Week 2000: JCE Resources in Food Chemistry
NASA Astrophysics Data System (ADS)
Jacobsen, Erica K.
2000-10-01
November brings another National Chemistry Week, and this year's theme is food chemistry. I was asked to collect and evaluate JCE resources for use with this theme, a project that took me deep into past issues of JCE and yielded many treasures. Here we present the results of searches for food chemistry information and activities. While the selected articles are mainly at the high school and college levels, there are some excellent ones for the elementary school level and some that can be adapted for younger students. The focus of all articles is on the chemistry of food itself. Activities that only use food to demonstrate a principle other than food chemistry are not included. Articles that cover household products such as cleansers and pharmaceuticals are also not included. Each article has been characterized as a demonstration, experiment, calculation, activity, or informational item; several fit more than one classification. Also included are keywords and an evaluation as to which levels the article may serve.

The JCE High School ChemEd Learning Information Center (CLIC) and Buyers Guide continue to be updated with each issue of the print Journal. Every month, links to articles of interest to high school teachers are added to CLIC. Links to all new book and media reviews are added to the Buyers Guide. Additions to the Biographical Snapshots of Famous Women and Minority Chemists (March 2001) and the updated WWW Site Review feature (July 2001) have been previously noted in this column. The Conceptual Questions and Challenge Problems feature has a useful, new tool, Chemical Concepts Inventory, that can be used to assess the level of chemistry misconceptions held by students.

Beyond Lecture and Non-Lecture Classrooms: LA-student interactions in Active Learning Classrooms
NASA Astrophysics Data System (ADS)
Gonzalez, Dayana; Kornreich, Hagit; Rodriguez, Idaykis; Monslave, Camila; Pena-Flores, Norma
Our expanded multi-site study on active learning classrooms supported by Learning Assistants (LAs) aims to understand the connections between three classroom elements: the activity, student learning, and how LAs support the learning process in the classroom. At FIU, LAs are used in a variety of active learning settings, from large auditorium settings to studio classroom with movable tables. Our study uses the COPUS observation protocol as a way to characterize LAs behaviors in these classrooms. With a focus on LA-student interactions, our analysis of how LAs interact with students during a 'learning session' generated new observational codes for specific new categories of LA roles. Preliminary results show that LAs spend more time interacting with students in some classes, regardless of the classroom setting, while in other classrooms, LA-student interactions are mostly brief. We discuss how LA-student interactions contribute to the dynamics and mechanism of the socially shared learning activity.

Brief structured physical activity in the classroom is effective for increasing student physical activity. The present study investigated the association between implementation-related contextual factors and intervention implementation after adoption of a structured classroom physical activity intervention. Six elementary-school districts adopted structured classroom physical activity programs in 2013-2014. Implementation contextual factors and intervention implementation (structured physical activity provided in past week or month, yes/no) were assessed using surveys of 337 classroom teachers from 24 schools. Mixed-effects models accounted for the nested design. Availability of resources (yes/no, ORs = 1.91-2.93) and implementation climate z-scores (ORs = 1.36-1.47) were consistently associated with implementation. Teacher-perceived classroom behavior benefits (OR = 1.29) but not student enjoyment or health benefits, and time (OR = 2.32) and academic (OR = 1.63) barriers but not student cooperation barriers were associated with implementation (all z-scores). Four implementation contextual factor composites had an additive association with implementation (OR = 1.64 for each additional favorable composite). Training and technical assistance alone may not support a large proportion of teachers to implement structured classroom physical activity. In addition to lack of time and interference with academic lessons, school climate related to whether administrators and other teachers were supportive of the intervention were key factors explaining whether teachers implemented the intervention. Evidence-based implementation strategies are needed for effectively communicating the benefits of classroom physical activity on student behavior and improving teacher and administrator climate/attitudes around classroom physical activity.
