Purpose: This article presented the results of studies that examined the appropriateness of the content, readability of printed learning materials and the effectiveness of external resources in ecology course offered at Universitas Terbuka. To integrate external resources, links to their websites were provided in the printed materials.…

Scientific reasoning, argumentation, and problem-solving are essential skills in 21st century. They help people solve problems in daily life. This study aimed to investigate the effect of local-based teaching materials on student's argumentation, scientific reasoning, and problemsolving skills using Science Project-based Learning (SPjBL).…

Overall, the major chemical information retrieval products Reaxys and SciFinder have several similarities such as numbers of document records, numbers of characterized substances (counting the PubChem Compounds integrated in Reaxys), and, possibly, numbers of different chemical reactions. Reaxys has well over 100 times the number of experimental…

Dropout and low academic performance at university level constitute a big current challenge. In this work, materials comprising different interactive tools were developed following instructional design, rooted in the cognitive load theory. They were applied in a first-year lecture chemistry course to tackle low academic performance and high…

A set of web-based stereochemistry tools which help students use virtual 3D models to translate Newman projections and chair conformations and assign "R/S" labels to stereocenters from 2D dashed-wedged structures is described. These tools are unique in the way they link 2D dashed-wedged structures to 3D models to help students develop…

Noncovalent interactions determine the three-dimensional structure of macromolecules and the binding interactions between molecules. Students struggle to understand noncovalent interactions and how they relate to structure-function relationships. Additionally, students' difficulties translating from two-dimensional representations to…

In Anatomy and Physiology courses, students often struggle with visualizing structures, or processes, that occur at the cellular level, such as capillary exchange. Whenever available, models can be vital to students' understanding of a topic, particularly when they can be constructed by students in real time. To demonstrate capillary exchange to…

At universities across the United States the epistemological beliefs of students have been observed to deteriorate after a semester of instruction in an introductory physics course. What this indicates is that after taking a course in physics most students, for example, may become less capable of delineating between evidence-based reasoning and…

Federal legislation requires equitable access to education for all students at all levels, including in the postsecondary setting. While there have been a few studies in the chemistry education research literature base focused on how to support students with specific disabilities, this work seems to exist as a separate stream of research without…

We have developed, implemented, and assessed a teaching-learning sequence that aims to enhance students' understanding of the divergence and curl of electromagnetic fields. We designed guided-inquiry worksheets based on student difficulties we identified during semiquantitative and qualitative studies and discussions in the literature. A multiple…

It is not uncommon for students to find themselves underprepared when entering a post secondary institution. In additional to lower levels of academic achievement, underprepared students may not be aware that they lack the skills needed to be successful and effectively acquire and process information. Because of this, students that enter…

In recent years, interactive computer simulations have been progressively integrated in the teaching of the sciences and have contributed significant improvements in the teaching-learning process. Practicing problem-solving is a key factor in science and engineering education. The aim of this study was to design simulation-based problem-solving…

This research was aimed at developing printed teaching materials of Atomic Physics PEFI4421 Course using Research and Development (R & D) model; which consisted of three major set of activities. The first set consisted of seven stages, the second set consisted of one stage, and the third set consisted of seven stages. This research study was…

When we administered the Test of Understanding of Vectors (TUV) to students who were completing a physics university remedial course (which covers subjects of a traditional high school physics course), we observed that they had considerable difficulties in interpreting the dot product as a projection. As a result of this, we decided to design a…

This study examined the effects of integrating instructional materials in Facebook on students' awareness and practice of laboratory safety. A quasi-experimental pretest-posttest two-group design was used in the study. The results indicate: 1.) The exposure to (Online Social Networking-Based Health Education) OSNBHE can improve students' awareness…
