Students with strong metacognitive skills are positioned to learn and achieve more than peers who are still developing their metacognition. Yet, many students come to college without well-developed metacognitive skills. As part of a longitudinal study on metacognitive development, we asked when, why, and how first-year life science majors use…

Learning effective science writing is an important component of becoming a scientist, but it can also be difficult to master. Even though the lab report has a long history in science education, there are still lingering issues that impact life science instructors and students. This dissertation is a coherent body of three interrelated research…

Take-home examinations were utilized during the COVID-19 pandemic for upper-level analytical chemistry lecture courses. The questions were often scenarios which required the students to determine the best type of instrument to use and how to go about the experiment. Answers submitted were well thought out and detailed, showing that the students…

In Massive Open Online Courses (MOOCs), learners can post both text comments and overall ratings regarding the courses. There is growing interest in assessing the consistency of online reviews and the determinants of learner satisfaction. This study analyses the disconfirmation effect between textual review topics and the determinants of learner…

In this study, it was aimed to examine the effects of inquiry-based activities supported by web 2.0 tools on the attitudes of students towards the chemistry lesson in the unit of 'Acids, Bases and Salts' in the 10th grade chemistry lesson. Considering the relevant achievements in the 2018 chemistry curriculum and using the web 2.0 tools Padlet and…

The development of equitable grading systems that provide students with effective feedback and provide instructors with an efficient means of assessment are of deep interest to chemical educators. A recent trend in chemical education, and STEM education more broadly, has been the use of specifications, or specs, grading that emphasizes mastery of…

Radiochemistry faces a well-documented training and recruitment crisis. Older radiochemists are retiring, and fewer young people are studying radiochemistry. In turn, this is leading to a shortage in newly qualified radiochemists, as well as a loss of historical knowledge (as know-how is often not passed-on). Here, we analyzed the relevance of the…

A novel undergraduate analytical chemistry experiment involving the identification and quantification of linalool in essential oils was developed. The experiment uses the internal standard method with headspace solid phase microextraction (SPME) and gas chromatography--mass spectrometry (GC-MS). This method is applicable to any linalool-containing…

The unforeseen COVID-19 pandemic forced educational institutions to shift to a remote or distance-learning mode. As a result, classes were offered online, and this shift in teaching modality presented great challenges, especially in teaching laboratory courses. While several options are available, we evaluated the use of (i) videos of lab…

Student enrollments in online college courses have grown steadily over the past decade, and college administrators expect this trend to continue or accelerate. Despite the growing popularity of online education, one major critique in the sciences is that students are not trained in the hands-on skills they may need for the workforce, graduate…

During the COVID-19 pandemic, many colleges switched to online or hybrid formats for both lecture and laboratory course delivery. While virtual experiments, that is, "dry lab" experiences, teach students chemical theory, it is essential for students in chemistry laboratories to participate in hands-on laboratory activities. These…

The two-semester General Chemistry laboratory sequence for nonchemistry majors at James Madison University has recently made the transition from expository, confirmation experiments to project-based (first semester) and research-based (second semester) curricula; this narrative will describe the development and current state of the Brewing Science…

My dissertation is a pre-mid-post-test, quantitative research design, including surveys and written assessments, to answer these research questions: 1. How do students' science mindset vary over time when engaged in science inquiry activities? Is there a difference between male and female students? 2. Is there a relationship between 7th grade…

Due to the COVID-19 pandemic, mandatory changes were required in the field of education, as in many other fields. One of these fields is a teacher training programme, which includes teaching practice. It has become of great importance that pre-service science teachers, who frequently include experiments in their teaching practices in face-to-face…

This study examines learners' issues in learning the preparation and qualitative analysis of salts topic from Malaysian chemistry teachers' perspectives. The researchers adopted a qualitative design and conducted semi-structured interviews with sixteen informants who have experience of teaching chemistry for more than five years. They were…
