Biology is a complex science that includes different subjects. As a result, misconceptions, confusion and misleading are common problems in biology education. In this study, it was aimed to determine the learning of pre-service science teachers about food web. The research, using the case study, was conducted in 2019-2020. The study group of the…

One of the key agendas for the emerging field of disciplinary-based education research is the evaluation of the trajectory of disciplinary knowledge development from novice to expert. However, with the ongoing promotion of student-centered and collaborative undergraduate science classrooms, it is unknown how peer discourse during these exercises…

This study investigated the effects of teachers' use of "focus questions" on students' knowledge structures and classroom teaching-learning process by re-analyzing selected data from a quasi-experimental pre-post video study (Wadouh, 2007). Focus questions are content-related anchoring questions highlighting the key content taught in…

This study follows two groups of students (67 in all) through the 3 years of their high school biology education and examines the development of their systems thinking--specifically their models of the human body as a system. Both groups were composed of biology majors, but the students in one group also participated in a PBLbased extension…

Historically, students have been viewed as empty vessels and passive participants in the learning process but students actually are active forming their own conceptions. One way student learning is impacted is through assessment. Alternative assessment, which contrasts traditional assessment methods, takes into account how students learn by…

Knowledge structure is an important aspect for defining students' competency in biology learning, but how knowledge structure is influenced by the teaching process in naturalistic biology classroom settings has scarcely been empirically investigated. In this study, 49 biology lessons in the teaching unit "blood and circulatory system" in…

Introductory tertiary level science classes (i.e., at the university or post-compulsory school level) including those for biology face increasing diversity in intake. Previous research has indicated university level teachers assume a certain level of prior knowledge which may or may not be possessed by such students. This report focuses on the use…

Undergraduates (n=25) participated in a study designed to describe and evaluate the use of concept mapping in teaching a college course on evolution; determine whether students' concept maps reveal "critical junctures" in learning as the course unfolds; and assess the impact of concept mapping on students' study practices and on…

A small set of relationships has been identified which appears to be sufficient for describing all molecular and cellular reactions and structures discussed in an introductory biology course. A precise definition has been developed for each relationship. These 20 relationships are of four types: (1) analytical; (2) spatial; (3) temporal; and (4)…

This paper analyzes the hardware and software features that would be desirable in a computer-based semantic network system for representing biology knowledge. It then describes in detail a prototype network of molecular biology knowledge that has been developed using Filevision software and a Macintosh computer. The prototype contains about 100…

Web-based learning has been proposed as a convenient way to provide professional development experiences. Despite quantitative evidence that online instruction is equivalent to traditional methods (Russell, 2001), the efficiency of this approach has not been extensively studied among teachers. This case report describes learning in an online…

Reports on the relationship between students' propositional knowledge, measured by concept mapping tasks, and their study strategies, measured by self-report questionnaires, as it relates to the concept of photosynthesis as presented in a first-year biology course. Results indicate that involved, purposeful study strategies, prompted by relevant…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
