Numerous studies have proven the learning benefits of concept maps in science subjects, particularly for students with low prior knowledge. There is a scarcity of research dedicated to the examination of chemistry courses at the university level, and the findings pertaining to academic performance in that subject exhibit a lack of consistency.…

Teaching Experimental Sciences is a compulsory subject in the Bachelor's Degree in Primary Education (BDPE). It belongs to the discipline of Education and to the field of "Knowledge of the social and natural environment", and consists of a total of 24 ECTS, of which 6 ECTS correspond to "Teaching Natural Sciences" (TNS). This…

General chemistry is the first undergraduate course in which students further develop their understanding of fundamental chemical concepts. Many of these fundamental topics highlight the numerous conceptual interconnections present in chemistry. However, many students possess incoherent knowledge structures regarding these topics. Therefore,…

Knowledge is not simply a collection of facts, principles, and formulas; instead, meaningful knowledge is organized around core concepts that guide peoples' thinking about a subject. Therefore, knowledge organization is recognized as an important component of understanding learning and teaching. In this research, knowledge organization of two…

Chemistry courses remain a challenge for many undergraduate students. In particular, first-semester organic chemistry has been labeled as a gatekeeper with high attrition rates, especially among students of color. Our study examines a key factor related to conceptual understanding in science and predictive of course outcomes-knowledge structures.…

This study explored the effectiveness of an inquiry-based cellulase laboratory unit in promoting inquiry in undergraduate students in biotechnology. The following tools were used to assess the students' achievements and attitude: conceptual understanding test, concept mapping, students' documents, CLES questionnaire, students' self reflection, and…

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)…

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…

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…

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…
