Animal cell culture is a core laboratory technique in many molecular biology, developmental biology, and biotechnology laboratories. Cell culture is a relatively old technique that has been sparingly taught at the undergraduate level. The traditional methodology for acquiring cell culture training has been through trial and error, instruction when…

An extremely simple, inexpensive, and safe method is presented, which emulates nucleic acids isolation and electrophoretic analysis as performed in a research environment, in the context of a secondary school hands-on activity. The protocol is amenable to an interdisciplinary approach, taking into consideration the electrical and chemical…

"Match Game" is a simple game designed through which students could learn the names of all lab equipment and glassware that they would encounter during the school year. The game leads into a student-based discussion during which they carefully think about proper uses for each piece of labware.

This article describes a few novel acid-base experiments intended to introduce students to the basic concepts of acid-base chemistry and provide practical examples that apply directly to the study of biology and the human body. Important concepts such as the reaction between carbon dioxide and water, buffers and protein denaturation, are covered.…

The teaching faculty for this course sought to address their own concerns about the quality of student learning in an impersonal large lecture biology class for majors, the difficulties in getting to know each student by name, and difficulties in soliciting answers and reactions from the students during the lecture. Questions addressed by this…

Articles about the pendulum in four journals devoted to the teaching of physics and one general science teaching journal (along with other miscellaneous articles from other journals) are listed in three broad categories--types of pendulums, the contexts in which these pendulums are used in physics teaching at secondary or tertiary levels and a…

Background: This study examines emotion regulation strategies used by children of mothers with childhood-onset depression (COD) and children of never-depressed mothers (NCOD). Methods: Participants were 49 COD offspring (ages 4-7) and 37 NCOD offspring (ages 4-7) and their mothers. Emotion regulation strategies were assessed observationally during…

Although laboratory activities are widely acknowledged as being fundamental to the teaching of science, many secondary science school teachers have limited knowledge of how to design and run effective teaching laboratories. Utilising a situated cognition theoretical framework, we discuss our collaborative efforts to develop a laboratory based…

Many language education scholars and professionals consider that the ideal way to connect their classrooms to the Internet is to use Internet-connected computer labs in the school. Many publications cater to the needs of teachers who work in such ideal environments (Dudeney 2000; Eastment 1999; Teeler and Gray 2000; Warschauer, Shetzer, and Meloni…

Studies of gene expression following fear conditioning have demonstrated that the inducible transcription factor, "egr-1," is increased in the lateral nucleus of the amygdala shortly following fear conditioning. These studies suggest that "egr-1" and its protein product Egr-1 in the amygdala are important for learning and memory of fear. To…

Up until a short time ago the Y chromosome played the role of the juvenile delinquent within human chromosomes. It was considered to be rich in junk, short on genes, and rapidly degenerating. Now the Y chromosome is growing up by providing a means for investigating human migration. Through the use of genetic markers on the Y chromosomes, students…

Contemporary mathematics education is at a crossroads. It has become exposed to forces, both static and dynamic, that pose a challenge to its traditional place in academia. Mathematics has a long-established status as perhaps the most critical foundation for analytical knowledge. But the manner in which mathematics instructors choose to respond to…

A. N. Leontiev (1978) introduced the philosophical concept of practice, or "objective activity" into psychology to reconsider its foundations, and in this context he elaborated the concept of the object of activity. This article deals with the co-formation of an object of a collective activity and of the goals, motives and capabilities…

Although the use of computers in secondary school writing centers has been pioneering in some instances, it has at other times been problematic. It is important to be clear at the outset that using particular technologies for the sake of those particular technologies is a bad idea. While technologies are always present in our lives, they are…

Writing centers offer students the means to success. The Reading Writing Center (RWC) at University High School in Orlando, Florida, serves a diverse population of more than 3,700 students. The center serves dual purposes. A classroom side operates as a demonstration space where the author, who is the center's director, leads and sometimes…
