Computational thinking is a contemporary science and engineering practice that has been introduced to the US science classrooms due to its emphasis in the "Next Generation Science Standards" (NGSS). However, including computational thinking into science instruction may be challenging. Therefore, for biological evolution (an essential…

There are numerous influential factors contributing to students' successful learning in introductory chemistry courses. One popularized factor is mathematical preparedness as gauged by a prerequisite mathematics grade or a standardized exam score. Less well known factors are students' attitude toward the subject of chemistry or students'…

First-semester general chemistry is a known "gatekeeper" course due to its high failure rate. These higher education courses are taken by students who for the most part are regularly admitted freshmen, yet many struggle to succeed. In this investigation researchers from six higher-education institutions of varied sizes with student…

This paper seeks to investigate how students' performance in Chemistry can be enhanced by using kitchen resources in Calabar. The kitchen resources used included a piece of white paper, a swab, lemon juice and candle. These were used to show that paper cellulose was oxidized by flame due to the catalysis of lemon juice acid. Other materials used…

This study utilized the quantitative meta-analysis technique to integrate chemistry education research findings conducted in the Philippines covering the period 2005-2016. It aimed to describe and examine the effects of teaching methodologies on academic performance in the secondary chemistry teaching-learning process. A search procedure and broad…

This study examined the effectiveness of computer-assisted and excursion strategies on secondary school students' achievement in Biology towards sustainable development. The study adopted quazi experimental research design. The population consisted of all the biology students in public senior secondary schools in South West, Nigeria. The sample…

At an Extension youth agricultural science center, our team developed and pilot tested a five-lesson weather and climate science curriculum for middle school-aged youths. As part of the endeavor, we conducted an item analysis of the five worksheets used across the lessons and determined relationships between worksheet scores and pretest/posttest…

This applied dissertation was designed to determine if there is a difference between students' gender, ethnicity, and age and their performance in General Chemistry I at a Christian University in Florida. Many scientific studies reveal the existence of a gender performance gap in chemistry: women mostly underperform men. Certain factors reported…

The effect of PowerPoint Presentation-based (PPPb) quiz to the students' scores has been rarely studied. It is the intention of this research to understand the effect of PPPb quiz to students score in wave motion and the students' experiences under such a strategy. This research used a mixed approach: quasi-experimental to learn if scores gain was…

Scientific literacy is the ability which must be owned by the students to analyze and apply the concept of science in solving daily life problem. This research aims to know the correlation between scientific literacy and science learning achievement at State Junior High Schools. This research used a quantitative approach with correlational type.…

We discuss an investigation of the difficulties that students in a calculus-based university introductory physics course have with electric field and the superposition principle for the case of a continuous charge distribution and how that research was used as a guide in the development, validation, and evaluation of a tutorial on these topics to…

The structure and definition of professional knowledge is a continuing focus of science education research. In 2012, a pedagogical content knowledge (PCK) summit was held and it suggested a model of professional knowledge and skill including PCK, which was later often called the Consensus Model (Gess-Newsome, 2015. A model of teacher professional…

In this exploratory study, we attempted to measure potential changes in teacher knowledge and practice as a result of an intervention, as well as trace such changes through a theoretical path of influence that could inform a model of teacher professional knowledge. We created an instrument to measure pedagogical content knowledge (PCK), studied…

There is a significant concern about students' achievement in reading comprehension. The study examined the reliability, validity, and slope of curriculum based measures in a content specific area -- science. Participants included students in 6th grade science classes. The curriculum based measures (CBM) being used consisted of vocabulary-matching…

Following professional development (PD), implementation of contemporary topics into high school biology requires teachers to make critical decisions regarding integration of novel content into existing course scope and sequence. Often exciting topics, such as neuroscience, do not perfectly align with standards. Despite commitment to enacting what…
