The pedagogical content knowledge of South African life sciences teachers teaching evolution for the first timeMolefe, Lehlohonolo Pauline Desiree 08 January 2014 (has links)
A research report submitted to the Faculty of Science in partial fulfilment of the requirements for the degree of Master of Science
Johannesburg, June 2013. / This study was motivated by the introduction of the topic of evolution in the Grade 12 Life Sciences curriculum in South African high schools in 2008. Many Life sciences teachers were concerned about their preparedness to teach evolution as this topic was new to them as well. They were worried about their ability to teach evolution as many felt that their content knowledge was inadequate to effectively teach evolution. The aim of this study was to investigate the nature and the extent of the pedagogical content knowledge of Life Sciences teachers who were going to teach evolution for the first time in South African high schools in 2008. This study used a five-category model of pedagogical content knowledge adapted from Shulman.
Data were collected from two different samples from teachers who were attending workshops which were aimed at alleviating the teachers’ concerns and fears about evolution and to help them prepare to teach the topic of evolution. The first workshop was held at the end of the second school term in 2008, just a few weeks before many teachers were meant to start teaching evolution. The second workshop was held during the period when all teachers were supposed to have started teaching evolution, and that was in August 2008. The first group of teachers comprised 39 teachers who attended the evolution workshop during the SAASTE conference and the second group comprised 40 teachers attending the evolution workshop organised for NAPTOSA.
The questionnaires were designed to address the five categories in the pedagogical content knowledge model used in this study. Seven activity-based questionnaires were used to gather data from two convenience samples consisting of two groups of teachers. The questionnaires investigated the nature and extent of the teachers’ knowledge of the evolution content they were supposed to teach; their knowledge of the teaching and learning difficulties regarding evolution; knowledge of the preconceptions and misconceptions associated with evolution; knowledge of appropriate methods and strategies to teach evolution and their curricular knowledge. Open-coding and frequency counting were used to analyse the data. The data revealed that the some teachers over-estimated their knowledge of the evolution subject matter, many harboured misconceptions about evolution. Further analysis of data revealed that many did not know of different approaches and strategies they could use when teaching evolution and that they did not know of the different additional resources they could use when teaching evolution. In general the teachers’ knowledge levels for teaching evolution, in all the five categories of pedagogical content knowledge was low, an indication that the teachers were ill-prepared for teaching evolution.

High school students achievement of college level work through the phase achievement system (PAS)Lassen, Dwight D. 01 August 1974 (has links)
Senior high school students in a Human Biology course were given college level work through the Phase Achievement System (PAS), a biology course at Brigham Young University (BYU). Statistical analysis showed significant growth in high school student learning through the PAS. When ability to work with PAS was measured, significant differences between the high school and college groups were not evident. A high percentage of college and high school students dropped out of the PAS, probably becasue students could fail at the PAS without experiencing academic failure.

A comparison of teams-games-tournaments (TGT) and traditional classroom methods in high school biologyDechow, Rebecca Ross January 1983 (has links)
Since 1970, researchers at Johns Hopkins University have studied the effects of a game technique called the tearns-games-tournament method on the achievement scores, attitudes, and classroom process of elementary and junior high students. Their findings raised many questions about the applicability of team-games to affect achievement at the high school level or in subject areas other than math and English. In 1980, the National Science Foundation allocated funds for the creation of TGT materials for seventh-grade science, even though research of its effectiveness for science courses had not been conducted.
This study was designed to provide answers to the following questions: Would high school students playing teams-games-tournaments have greater academic achievement in a high school biology course than students in classes using traditional classroom methods? Would high school students in TGT classes have greater retention of knowledge after a delayed period of time than those students in classes using traditional classroom methods? Would high school students in TGT classes have more positive attitudes toward the subject of biology than students in classes using traditional classroom methods? Would high school students like TGT better as a means for studying chapter material than traditional methods?
Eight biology classes were involved in the seven-week treatment period. Analysis of variance was used to compare control and experimental groups for (1) pre-test cognitive knowledge, (2) post-test cognitive knowledge, (3) delayed post-test cognitive knowledge, (4) pre-test attitudes towards biology, and (5) post-test attitudes towards biology. Analysis of covariance was computed using I.Q. and pre-test scores as covariates for post-test cognitive means and delayed post-test cognitive means. A dependent t-test was computed for attitudes of experimental classes towards team-games.
TGT had no significant effect on the biology achievement scores or attitudes towards biology of high school students in this study. Experimental classes did like team-games and sustained their attitudes towards them for the duration of the study. / Ed. D.

The Effect of the Use of Laser Video Disc on Achievement, Attitude, and Confidence of High School Biology StudentsGarza, Federico (Federico Angel) 08 1900 (has links)
The purpose of the study was to determine the effects of level III video disc instruction on high school biology students. There were three areas studied: students' achievement in biology, students' attitude toward biology, and confidence. The experimental group consisted of 70 biology students. The control group also consisted of 70 biology students. The teacher of the experimental group used level in video disc instruction to teach about invertebrates, vertebrates, human systems, and plants throughout the semester. The teachers of the control group taught the same topics during the same period using the traditional lecture method and without level III video disc instruction. Students took the Biology Achievement Test, the Purdue Master Attitude Scale, and the Confidence in Learning Inventory before and after the treatment period. A t-test on the pretest scores of the experimental group and the control group showed no significant difference between the two groups. The experimental group also took the Technology Preference Survey after the treatment period.
