This study analysed the characteristics that children in the initial stages of schooling attribute to living beings. Interviews were conducted with 138 children aged 3-7 years in a school in the Spanish city of A Coruña, Galicia. Aspects found in pen-and-paper activities dealing with living beings, provided by the teachers (158 in total) at this…

The effect of psychological resilience as a buffer against anxiety was investigated in a sample of 39 boys with high-functioning autism spectrum disorder (ASD) via individual online questionnaire responses to standardised inventories for assessing anxiety and psychological resilience. Ability to handle problems, make good decisions, think before…

This exercise demonstrates the principle of parsimony in constructing cladograms. Although it is designed using mammalian cranial characters, the activity could be adapted for characters from any group of organisms. Students score categorical traits on skulls and record the data in a spreadsheet. Using the Mesquite software package, students…

Science teachers inspire in part by their constant adaptation to the learning needs of their students and to evolving content, curriculum, technology, and student populations. Innovation--bringing novel things to a situation to confer a benefit--is an integral part of teaching overall, and in especially inspired science teaching. While innovation…

Technological pedagogical content knowledge TPACK refers to the knowledge set that teachers currently use to further improve the quality of their teaching and assist their students in learning. Several TPACK models have been proposed, either for discussing TPACK's possible composition or its practical applications. Considering that…

Dissection of lab specimens is a common procedure in science classrooms, yet there are many unasked and unexamined questions relating to this practice. In addition to ethical considerations, there are personal and environmental health impacts of using conventional dissection, which has historically included animals and animal organs embalmed in…

The purpose of this study was to determine if significant relationships exist for any of the variables, age, gender, previous GPA, test scores (ACT, Compass), number of accumulated credits, and student success in Biology. This study strived to determine what academic/admissions data can be used to determine the likelihood of student success in…

After decades of development and use in a variety of application areas, Quantitative Structure Property Relationships (QSPRs) and related descriptor-based statistical learning methods have achieved a level of infamy due to their misuse. The field is rife with past examples of overtrained models, overoptimistic performance assessment, and outright…

By recognizing opportunities to engage in outdoor experiences, provide subsistence, and foster an environmental ethic, all in their own communities, students might become more inclined to advocate for environmentally sustainable activities in their own regions. This author believes that fishing can aid in fostering a certain ethical view of the…

Pheromones are chemicals used to communicate with members of the same species. First described in insects, pheromones are often used to attract mates but in social insects, such as ants and bees, pheromone use is much more sophisticated. For example, ants use pheromones to make foraging trails and the chemical and physical properties of the…

How effective is training frogs to jump? This is perhaps the most frequent question in biology that is subjected to statistical analysis: does a treatment make a difference? One can examine whether there is indeed a training effect, by first assuming the opposite. That is, the authors assume that training has no effect on the mean distance jumped.…

It's that time of year again, when avoiding the flu is on everyone's mind. As we brace ourselves for possible flu outbreaks, the need to understand biological issues related to this virus becomes clear. Through modeling, the lesson presented in this article helps students understand how the influenza virus (or flu) evolves and how flu vaccines are…

Terms to be familiar with before you start to solve the test: ion exchange chromatography, polynucleotides, oligonucleotides, radioactive labeling, template, primer, DNA polymerase, reverse transcriptase, helicase, nucleoside triphosphates, nucleoside diphosphates, nucleoside monophosphates, nucleosides, 5'-end and 3'-end, bacteriophage,…

General biology courses (for majors) are often transferred from one institution to another. These courses must prepare students for upper division courses in biology. In Colorado, a Biology Transfer Articulation Agreement that includes general biology has been created across the state. An evaluation was conducted of course grades in two upper…

Research Findings: Prior research indicates that shared book reading is an effective method for teaching biological concepts to young children. Adult questioning during reading enhances children's comprehension. We investigated whether adult prompting during the reading of an electronic book enhanced children's understanding of a biological…
